    The present invention relates to a floor cleaning device, comprising a brush device, which with respect to a working position of the brush device, which occupies this when cleaning a horizontal surface, rotatable about vertical axes of rotation and brushes at least partially surrounding and downwardly open brush housing, in which opens at least one steam outlet for steam generated by a steam generator and / or at least one hot water outlet, wherein the brush device in the working position of at least one suspension unit of the floor cleaning device, via which the floor cleaning device is fastened to a vehicle, with a pushing force for movement the brush device can be acted upon in a direction of travel.
    Sweepers attached to floor coverings often use rotary brush sweepers. For cleaning substrate with sticky contaminants, such as Chewing gum, a mechanical cleaning alone is often not enough. A commonly used method of chewing gum removal in practice is to heat the chewing gum by means of a heat source prior to mechanical removal and then remove it by means of a brush. Frequently, steam is used for this purpose. To improve the cleaning performance also washing-active substances are often used.
    AT 412 189 B shows a floor cleaning appliance for cleaning heavily soiled subsurface, which has a steaming section with several steam outlets and a brush arrangement arranged behind it with three brushes arranged on a rotatable brush plate. The floor cleaning device is pushed by the user over the surface to be cleaned. The brushes are mechanically connected to each other via a belt drive, wherein a rotation of the motor-driven brush plate leads to a rotation of the brushes.
    DE 20 2013 005 169 U1 discloses a brush device whose brushes are fastened to brush carriers which are capable of oscillating movement relative to a brush housing. Steam is introduced into the brush housing. The brushes are rotatably mounted on the respective brush holder, but they are not rotationally driven. Each brush is individually displaceable relative to the respective brush holder in the vertical direction against a counterforce generated by a respective spring. On an uneven surface, the brushes, when viewed in the vertical direction, assume different positions so that the springs are compressed differently. Depending on the travel, the brushes are pressed against the ground due to the spring characteristic with different contact pressure, which is why the cleaning performance of the individual brushes is different for uneven floors.
    By prior use, a floor cleaning device of the type mentioned with a brush device according to DE 20 2013 005 169 U1 is known. The brush device is suspended here via a suspension unit on a vehicle, from which the brush device is pushed over the substrate to be cleaned. Uneven floors can only be accommodated to a limited extent by this floor cleaning device. When driving on hills or troughs and overcoming step-like obstacles, such. Curbs, it can lead to a high load of individual brushes, and subsequently to a heavy wear of the brushes.
    The object of the invention is to provide an advantageous floor cleaning device of the aforementioned type, by which the operation is improved in uneven floors, with a high cleaning performance is achieved even in the case of uneven floors.
    According to the invention, this is achieved by a floor cleaning device having the features of claim 1.
    In the floor cleaning device according to the invention, it is provided that at least one force member of the floor cleaning device cooperates with the brush device, wherein the brush device in a, relative to the direction of travel, rear portion of the brush device against a force applied by at least one force member counterforce in the vertical direction relative to the at least one suspension unit can be raised.
    When driving on bumps, e.g. Elevations or step-like obstacles, with the floor cleaning device, the brush device in the vertical direction relative to the suspension unit, i. relative to the vehicle to be moved. This protects the individual brushes, since a strong deformation of the brush bristles, by dodging the brush device up, can be prevented. Conveniently, the brush device can be raised in the vertical direction against a counterforce applied by the at least one force element, which changes by less than 10% over the possible attachment, and is particularly preferably constant over the possible attachment. In particular, such a force member can be realized in the form of a piston-cylinder unit. This also has the advantage that a simple variation of the counterforce can be made by pre-selection of the acting in the piston-cylinder unit backpressure. Other force members, e.g. electromotive operated power links are conceivable and possible.
    In another possible embodiment, the force member could comprise a mechanical spring, wherein the counterforce changes over the lifting due to the spring characteristic. When using a compression spring used as a force member, a larger deflection in the vertical direction leads to a greater compression of the spring, resulting in a rising with the deflection
    Drag force results.
    The brushes advantageously have a trimming with bristles. The bristles are preferably made of metal, in particular of steel. Also bristles of plastic or other well-known in the art materials are conceivable and possible.
    The brush device preferably has, in a rear region of the brush device with respect to the direction of travel, an axle unit which, together with the at least one suspension unit, forms a horizontal pivot axis in the working position of the brush device, which occupies the same when cleaning a horizontal surface, around which the brush device faces the suspension unit or the vehicle is pivotable, wherein the pivot axis is movable at least in the vertical direction. The axle unit is thus movable relative to the suspension unit in the vertical direction.
    In operation, the floor cleaning device is pushed by a vehicle over the surface to be cleaned, wherein the suspension unit of the transmission of the thrust or the transmission of the movement of the vehicle is used on the brush device in the direction of travel. Depending on the nature of the substrate, the friction conditions between the brushes and the surface to be cleaned are different. Especially when cleaning substrates with a high coefficient of friction there is a risk that, based on the direction of travel in a rear region of the brush device arranged brushes are lifted from the ground or at least the force with which they are pressed against the ground, is greatly reduced while Brushes arranged in a front area of the brushing device are pressed against the ground with an increased force. In a force acting in the direction of lifting the rear portion of the brush device caused by the friction of the brushes on the ground, the force member according to the invention exerts a counterforce on the brush device around the rear portion of the brush device and the brushes located in the rear portion of the brush device to keep the ground pressed.
    Particularly preferably, the floor cleaning device has at least one lifting element cooperating with the axle unit, from which a torque acting about the pivot axis can be exerted on the axle unit. By virtue of the torque which can be exerted by the lifting element, the brush device can be pivoted relative to the suspension unit of the floor cleaning device about the pivot axis. In this case, the brush device with the at least one lifting member can be conveniently pivoted into a passive position, in which the brush device and the brushes are lifted from the ground.
    In an advantageous embodiment of the invention, by means of the lifting member in the working position of the brush device, a torque on the axle unit exercisable. This makes it possible, when cleaning a substrate, to relieve the brush arranged in a relative to the direction of travel of the floor cleaning device front portion of the brush device by means of the at least one lifting member. Advantageously, the torque exerted by the at least one lifting member in the sense of relieving the brushes arranged in the front region of the brushing device can hereby be adapted to the friction coefficient of the substrate.
    Due to the interplay of the at least one force member and the at least one lifting member, a largely uniform distribution of the pressing forces relative to brushes located farther forward and farther back in the direction of travel can be achieved. As a result, the cleaning performance can be significantly increased and high wear of the arranged in the front region of the brush device brushes can be prevented.
    The force member and / or the lifting member is supported or rely favorably on the suspension unit for the application of the counterforce or the torque. Thus, a stationary part of the force member and / or the lifting member with the suspension unit in a rigid or articulated connection. The entire soil
    Cleaning device can thus be removable from the vehicle as a whole. It is also possible in other embodiments of the invention for the force member and / or the lifting member to be supported or supported at another point on the vehicle.
    In a particularly advantageous embodiment of the invention, the axle unit is displaceably guided by the suspension unit in the vertical direction, wherein the suspension unit in the working position of the brush device acts on the axle unit of the brush device with the thrust force for moving the brush device in the direction of travel. In this case, the axle unit is conveniently held immovably in the horizontal direction relative to the suspension unit.
    In an alternative embodiment of the invention, the axle unit is also movable in the horizontal direction relative to the suspension unit. A pushing member of the suspension unit acts on the brush device in the working position of the brush device in this case conveniently below the height of the pivot axis on a counter to the direction of travel surface of the brush device with the thrust to move the brush device in the direction of travel. Thus, the suspension unit does not interact with the axle unit of the brush device to transmit the thrust. It is particularly favorable in this context if the thrust member is adjustable in height relative to a part of the suspension unit carrying the thrust member. The height can be adjusted to the friction coefficient of the ground.
    Both in the embodiment of the invention, in which the axle unit is guided displaceably in the vertical direction and held horizontally immovable, as well as in the embodiment in which the axle unit is movable in the vertical and horizontal directions, advantageously, the brush device as a whole about a parallel to Moving direction lying, in particular central, longitudinal axis relative to the suspension unit are tilted. An adaptation to bumps across the direction of travel is made possible.
    A possible embodiment of the invention provides that with respect to the working position of the brush device, which occupies this when cleaning a horizontal surface, at least one of the brushes of the brush device is adjustable relative to a cover part of the brush housing in a vertical direction and the brush of a through a Pressing unit exerted pressing force is pressed against the ground. In an alternative embodiment, it is provided that at least one pressing brush holder of the brush device is provided, on which at least two of the brushes of the brush device are each rotatably mounted about a vertical axis of rotation and which is pivotable about a horizontal Andrück brush holder pivot axis in the vertical Direction opposite the cover part of the brush housing is displaceable. The pressing-brush-holder pivot axis is acted upon in this case by a pressing force exerted by a pressing unit in the vertical direction, wherein the at least two brushes are pressed against the ground. Due to the adjustability of the brushes or the pressure-brush holder pivot axis in the vertical direction vertical adjustment of the individual brushes of the brush device to an uneven surface is possible, with small-scale unevenness can be compensated transversely and longitudinally to the direction of travel. Conveniently, based on the working position of the brush device, which occupies this when cleaning a horizontal surface, provided that at least one of the brushes of the brush device is held immovably in the vertical direction relative to the cover part of the brush housing or the brush device has at least one support brush support on the at least two of the brushes of the brush device are rotatably mounted about vertical axes of rotation and which is pivotable about a horizontal support brush holder pivot axis, which is held immovably in the vertical direction relative to the cover part of the brush housing. By the arrangement in the vertical direction immovably held brushes or non-displaceably held in the vertical direction relative to the brush housing support brush holder pivot axes, it is possible, the weight of the brush device or the forces acting on the brush device forces on the support brush holder or individually arranged brushes, which are held immovably in the vertical direction relative to the brush housing, to lead to the ground. This can be dispensed with additional support wheels on the brush device, which adversely affect the width of the brush device. In combination with the vertically adjustable brushes or the vertically displaceable Andrück-brush holder pivot axes of the Andrück brush holder, a uniform distribution of the weight of the brush device and the forces acting on the brush device forces can be achieved on all brushes of the brush device. This is particularly advantageous on uneven surfaces, since even with large relative differences in height of the substrate a good cleaning performance of the floor cleaning device can be achieved at all points of the substrate.
    The pressing brush holder and the supporting brush holder could also be referred to as rockers. The pressing-brush holder pivot axis or the support brush holder pivot axis forms a kind of rocking axis. Conveniently, exactly two brushes are arranged on a respective pressing brush holder and / or on the supporting brush holder. Differences in height between two brushes arranged on a supporting brush holder or on a pressing brush holder can be compensated for by pivoting about the pressing brush holder pivot axis or the supporting brush holder pivot axis.
    The respective supporting brush holder pivot axis of the supporting brush holder and / or the respective pressing brush holder pivot axis of the pressing brush holder is conveniently arranged eccentrically between two rotatably mounted brushes respectively on the supporting brush holder and / or on the pressing brush holder about the vertical axis of rotation , In an exactly central arrangement of the pivot axes seen in the direction of travel front of the brushes, especially at higher friction coefficients of the substrate would be exposed to a higher contact pressure and thus the wear of the brushes be unequal.
    By off-center arrangement more uniform distribution of the contact pressure can be realized on the arranged on the respective support brush holder or pressure brush holder brushes.
    In the brush housing of the floor cleaning device is conveniently operated with steam for pretreatment of the dirt, in particular for softening of chewing gum. Instead or in addition, it is conceivable and possible to use hot water.

    Embodiment of a floor cleaning device according to the invention.
    For clarity, not all components and elements are provided with a reference numeral in the figures.
    A first embodiment of the invention is shown in Figures 1 to 10, partially simplified and schematized. In Figures 1, 2 and 4-10, the floor cleaning device 1 is shown in the working position of the brush device 20, which occupies this when cleaning a horizontal surface 2. If the substrate 2 is different from the horizontal plane or has unevenness, the brushing device 20 can assume a working position deviating therefrom. In any case, the brushes 5 of the brush device 20 are in contact with the substrate 2 in the respective working positions of the brush device 20. The explanations regarding the embodiments of the invention shown in the figures relate, apart from explicit references to other working positions, to that working position of the brush device 20, which occupies these when cleaning a horizontal substrate 2.
    The floor cleaning device 1 has a brush device 20, which is suspended by a suspension unit 10 on a vehicle 4. In one, with respect to the direction of travel 3 of the vehicle 4, the rear area, the brush device 20 has an axle unit 22, which forms a horizontal pivot axis 13 together with the suspension unit 10. The brush device 20 is pivotable about the pivot axis 13 and allows a relative angular displacement between the brush device 20 and the suspension unit 10 or the vehicle 4. By pivoting the brush device 20 relative to the suspension unit 10, the brush device 20 can be brought into a passive position, in which brushes 5 are lifted from the ground 2 and are pivoted upwards, so that the brushes 5 are, for example, in a substantially vertical plane.
    For swiveling the brush device 20 relative to the suspension unit 10, the floor cleaning device 1 has a lifting element 14 cooperating with the axle unit 22, from which a torque acting about the pivot axis 13 can be exerted on the axle unit 22. The lifting member 14 is pivotally connected via the bolt 16 to the lever 24 of the axle unit 22, cf. Fig. 1 and 3. The lifting member 14 is executed in the embodiment as a piston-cylinder unit and hydraulically connected to a hydraulic unit, not shown for controlling the movement of the piston-cylinder unit. The hydraulic unit can be arranged on the floor cleaning device 1 itself or on the vehicle 4.
    In the exemplary embodiment, the axle unit 22 has a pivoting tube 29 pivotable about the pivot axis 13 and, in each case, an end face on this connecting part 37 for torsionally rigid connection of the brush housing 30 with the pivot tube 29 of the axle unit 22. At opposite ends, the axle unit 22 with the pivot axis 13 coaxially aligned guide pin 23. Each of these guide pin 23 passes through a thrust member 11 of the suspension unit 10th
    The respective thrust member 11 is integrally formed in the first embodiment of the floor cleaning device 1 with the suspension unit 10 and has a slot 15 in which the guide pins 23 of the axle unit 22 are guided displaceably in the vertical direction. To reduce the wear rolling bearings are conveniently provided on the respective guide pin 23, which allow a rolling of the respective guide pin 23 on the elongated hole 15 delimiting straight side walls. For reasons of clarity, the rolling bearings of the guide pins 23 are not shown in the figures. The oblong hole 15 delimiting side walls of the pusher member 11 serve to transmit the thrust or the transmission of the movement of the vehicle 4 in the direction of travel 3 on the guide pin 23 of the axle unit 22 of the brush device 20th
    In the working position of the brush device 20, which occupies this when cleaning a horizontal surface 2, the respective guide pin 23 is in a central position with respect to the possible Anhebewegs in the slot 15. Conveniently, a further to be explained in more detail below power element 12 of the floor cleaning device. 1 completely extended, cf. Fig. 1. In the passive position of the brush device 20 are both guide pins 23 at the upper end of the respective elongated hole 15, see. Fig. 3. The force member 12 may in this case, in contrast to the working position, be controlled so that it moves into a retracted position and the axle unit 22 holds above.
    Due to the mobility of the brush device 20 in the elongated holes 15, the brush device 20 in a, relative to the direction of travel 3, rear portion of the brush device 20 against a force applied by the force member 12 counterforce in the vertical direction relative to the suspension unit 10 can be raised. The relative movement of the brush device 20 relative to the suspension unit allows adaptation of the floor cleaning device 1 to uneven surfaces 2, e.g. in step-shaped obstacles, in which a deflection of the brush device 20 upwards relative to the vehicle 4 is necessary to ensure a good cleaning performance.
    The force member 12 acts, favorably directly, with the axle unit 22 of the brush device 20 together and is connected in the exemplary embodiment with an arranged on the pivot tube 29 condyle 25 with the axle unit 22.
    The force member 12 acts, based on the longitudinal extension of the pivot tube 29, centrally on the axle unit 22, see. For example, two force members 12 cooperating laterally with the axle unit 22 could also be provided. In the working position of the brush device 20, the counterforce exerted by the force member 12 acts along a vertical line of action which intersects the pivot axis 13.
    In the embodiment, the counterforce over the entire possible attachment is constant by the execution of the force member 12 as a piston-cylinder unit. By preselecting the hydraulic counter-pressure acting in the piston-cylinder unit, the amount of counterforce can also be set as required. The piston-cylinder unit is hydraulically connected to a hydraulic unit, not shown, for controlling the movement, which can be arranged on the floor cleaning device 1 itself or on the vehicle 4.
    Depending on the nature of the substrate 2 to be cleaned, the friction conditions between the brushes 5 and the surface to be cleaned are different. When cleaning substrates 2 with a high coefficient of friction, it could come without the force member 12 to raise the rear relative to the direction of travel 3 area of the brush device 20 from the substrate 2. Against such lifting of the rear brush 5, the force exerted by the force member 12 counteracting force acts. The force with which the front brushes 5 are pressed against the ground 2 is thereby reduced, and the pressure forces of the brushes 5 are divided more evenly.
    By means of the lifting member 14, the brushes 5 of the brush device 20, which are front-mounted in relation to the direction of travel 3 of the floor cleaning device 1, can be relieved by a torque acting about the pivot axis 13 when cleaning the substrate 2. In this case, the torque exerted by the lifting member 14 in the sense of relieving the brushes 5 arranged in the front region of the brushing device 10 can be adapted to the friction coefficient of the substrate 2. The application of the counterforce by the power member 12 and the exertion of torque by the lifting member 14 allow a largely uniform distribution of Andrückkräfte relative to in the direction of travel 3 further forward and further back arranged brushes 5. Since too strong or too lightly loaded brushes 5 the Reduce cleaning performance, the cleaning performance can be significantly increased with the force member 12 and the lifting member 14 and a high wear of the arranged in the front region of the brush device 20 brush 5 can be prevented.
    Due to the mobility of the guide pins 23 in the oblong holes 15, the brush device 20 can be tilted about a longitudinal axis 7 lying parallel to the direction of travel 3 relative to the suspension unit 10. The force member 12 is in this case connected by means of the condyle 25 articulated to the axle unit 22. The condyle 25 has for this purpose, for example, a ball joint. Also, the force member 12 is favorably hingedly connected to the bolt 16 by means of a ball joint, as is also provided in the embodiment. The longitudinal axis 7 is shown in Fig. 2 as an imaginary or virtual axis. This tiltability allows adaptation of the floor cleaning device 1 to unevenness of the substrate 2 transversely to the direction of travel 3. The slots 15 limit the Verkippwinkel the axle unit 22 relative to the suspension unit 10 with respect to the longitudinal axis 7 by a queuing of the respective guide pin 23 at the top or bottom End of the respective slot 15.
    The force member 12 is supported as the lifting member 14 from the suspension unit 10. The entire floor cleaning device 1 can therefore be removed as a whole by removing the suspension unit 10 with the brush device 20 from the vehicle 4. The attachment of the suspension unit 10 on the vehicle 4 can be realized by well-known, reversibly releasable fastening devices.
    The brush device 20 has in the working position, which occupies this when cleaning a horizontal surface 2, about vertical axes of rotation 6 rotatable brushes 5, which are surrounded by a brush housing 21 open at the bottom. In the brush housing 21 opens a plurality of steam outlets 35, which are supplied via steam lines 34 with steam generated by a steam generator. The steam generator for generating steam is conveniently arranged on the vehicle 4 and connected via corresponding, preferably flexible, lines to the steam lines 34. The steam generator could also be part of the floor cleaning device 1. The extracted dirt residues are conveniently collected on the vehicle.
    On three sides, the brush housing 21 on Abdichtschürzen 30, the sealing strips 31 rest in the working position on the substrate 2 and prevent the escape of steam from the brush housing 21 into the environment. In, relative to the direction of travel 3, the rear portion of the brush housing 21, a suction device 33 of the brush housing 21 for receiving the cleaning liquid or the dissolved from the substrate 2 dirt is arranged. The space bounded by the brush housing 21 and the substrate 2 in the working position could also be referred to as the working space of the floor cleaning device 1. Conveniently, the respective Abdichtschürzen 30 and arranged in the suction 33 sealing strips 31 are segmented. This ensures an alignment of the sealing strips 31 to the substrate 2 and a reliable seal in uneven floors. The sealing strip 31 of the Abdichtschürze is guided in a guide profile 32 in the vertical direction, see. Fig. 4. The sealing strips 31 of the suction device 33 are shown only schematically, see. Fig. 5. These are relative to the profile 38 of the suction device 33 displaced in the vertical direction.
    The steam allows the softening of dirt, in particular of chewing gum before the actual mechanical removal by means of the brush 5. In addition to steam, especially water vapor, it is also possible to operate the floor cleaning device 1 additionally with washing-active substances, which with the water vapor in the Brush housing 21 are initiated. The water vapor can be in the form of wet steam or dry steam. It is also possible to operate the floor cleaning device according to the invention with water at a temperature of at least 80 ° C, preferably of more than 90 ° C and to dispense with the use of Wasserdampfzu. There are then arranged instead of steam outlets 35 hot water outlets, which open into the brush housing 21. It is also conceivable that the floor cleaning device 1 has an additional steam apron, which is arranged relative to the direction of travel 3 in front of the brush housing 21 shown in the figures.
    In the exemplary embodiment, the brush device 20 comprises pressing-brush holder 40, on each of which two of the brushes 5 of the brush device 20 are rotatably mounted about a vertical axis of rotation 6. In the working position of the brush device 20, which occupies this when cleaning a horizontal substrate 2, a respective pressing brush holder 40 is pivotable about a horizontal Andrück brush holder pivot axis 41. The Andrück-brush holder pivot axis 41 is displaceable in the vertical direction relative to the cover part 27 of the brush housing 20 (based on the working position shown in the figures) and acted upon by a pressing force exerted by a pressing unit 44 in the vertical direction, wherein the two brushes 5 to the Underground 2 are pressed. In the exemplary embodiment, the pressing unit 44 is formed by a piston-cylinder unit. The contact pressure of the brushes 5 can be conveniently preselected by pre-selection of the hydraulic pressure, wherein the brushes 5 are pressed over the entire stroke of the piston-cylinder unit with a constant contact force against the ground 2. It is conceivable and possible, instead of a piston-cylinder unit to use compression springs or other Anpresseinheiten 44. The respective pressing unit 44 is held or supported in an articulated manner on a respective holding part 45, which is attached to the cover part 27 of the brush housing 21. About the two tabs 43 of the Andrück brush holder 40 and the pivot pin 42, the pressing unit 44 is pivotally connected to the Andrück brush holder 40, see. Fig. 8 and 9. In the embodiment, three pressing-brush holder 40 are provided, and more or less pressing brush holder 40 may be provided.
    In addition, the brush device 20 in opposite lateral areas in each case a support brush holder 50, on which two of the brushes 5 of the brush device 20 are rotatably supported about vertical axes of rotation 6. Each support brush holder 50 is pivotable about a horizontal support brush holder pivot axis 51. In contrast to the pressing-brush holder pivot axes 41, the supporting brush holder pivot axes 51 are held immovably in the vertical direction relative to the cover part 27 of the brush housing 20. For this purpose, the cover part 27 has guide plates 54 with oblong holes 55 which prevent the movement of the pivot pin 52 forming the supporting brush holder pivot axis 51 in the vertical direction. The elongated holes 55 allow a relative movement of the supporting brush holder 50 relative to the cover part 27 of the brush housing 21 in the horizontal direction in or against the direction of travel 3. The slot 55 has in the figures a much greater longitudinal extent in the direction of travel 3, as to the functionality of the ground -Cleaning device 1 is necessary. The representation serves only for a better representation of the function.
    Both the pressing brush holder 40, and the supporting brush holder 50 pass through two guide bottle 28 of the lid part 27, which limit the movement of the pressing brush holder 40 and the supporting brush holder 50 in the horizontal direction, see. Fig. 6 and Fig. 8. Between the guide flange 28 and the pressing brush holder 40 and the supporting brush holder 50 is a game provided to pivot about the Andrück brush holder pivot axis 41 and the support brush holder pivot axis 51 to allow it without causing any constraints. This is not shown separately in the figures.
    The brushes 5 are held immovably in the vertical direction with respect to the pressing brush holder 40 and the supporting brush holder 50. In other embodiments, it is conceivable and possible for the brushes 5 in the working position of the brush device to be displaceable in the vertical direction relative to the pressing brush holder and / or the supporting brush holder against a spring force exerted by a compression spring.
    A deflection of one of the two brushes 5 respectively held on the pressing brush holder 40 and on the supporting brush holder 50 in a vertical upward direction leads to a deflection of the other brush 5 in the opposite direction, by pivoting the pressing brush holder 40 or the supporting brush holder 5. Brush holder 50 to the Andrück brush holder pivot axis 41 and the support brush holder pivot axis 51. The Andrück brush holder 40 and the support brush holder 50 thus act similar to a rocker, the pressure forces of the respective brushes 5 divided due to the geometric design become.
    During a movement of the brush device 20 in the direction of travel 3 seen in the direction of travel 3 before the other brushes 5 are more heavily loaded due to the resulting frictional forces. The supporting brush holder pivot axis 51 of the supporting brush holder 50 and the pressing brush holder pivot axis 41 of the pressing brush holder 40 are therefore eccentrically arranged between the two brushes 5 supported on the supporting brush holder 50 and the pressing brush holder 40 in the exemplary embodiment. Due to the off-center arrangement of the pivot axes, a uniform distribution of the contact pressure on the brushes 5 arranged on the respective supporting brush holder 50 or pressing brush holder 40 is achieved.
    In the exemplary embodiment, the pressing brush holders 40 are arranged in the region between the supporting brush holders 50. The combination of the displaceable in the vertical direction Andrück brush holder pivot axes 41 of the Andrück brush holder 40 with the non-displaceable in the vertical direction support brush holder pivot axes 51, a uniform distribution of the weight of the brush device 20 and the forces acting on the brush device 20 forces on all Brushes 5 of the brush device 20 can be achieved. This is particularly advantageous for small-scale uneven floors, since a uniform cleaning performance of the floor cleaning device 1 can be achieved at all points of the substrate 2 by all brushes 5 of the brush holder 20 fit snugly on the substrate 2. By preselecting the hydraulic pressure with which the pressing unit 44 is operated, the pressing force can be adjusted accordingly.
    The supporting brush holder pivot axes 51 of the support brush holder 50 and the pressing brush holder pivot axes 41 of the pressing brush holder 40 are aligned parallel to each other and orthogonal to the direction of travel 3.
    The pressing-brush holder pivot axes 41 and the support brush holder pivot axes 51 each juxtaposed pressing-brush holder 40 and / or support brush holder 50 are arranged offset in the embodiment with respect to the direction of travel 3 to each other. In addition, the juxtaposed pressing brush holder 40 and / or supporting brush holder 50 are arranged overlapping with respect to the direction of travel 3. This makes it possible to nest the brushes 5, which are juxtaposed with respect to one direction orthogonal to the direction of travel 3, and thus overlap the areas swept by the brushes 5 when the brush device 20 moves in the direction of travel 3.
    Due to the design of the brush device 20 with the support brush holders 50 can be dispensed with additional support rollers, which would increase the width of the brush device 20 relative to the direction of travel 3. In other embodiments, however, it would also be conceivable and possible to provide instead of the support brush holder or additional support rollers.
    Each of the brushes 5 is individually rotatable in the exemplary embodiment by means of a respective motor 36 about a vertical axis of rotation. This is an individual driving the brush 5, z. B. possible with different rotational speeds or in different directions. By the opposite direction of rotation, for example, based on the direction of travel 3 consecutively arranged brushes 5, the cleaning performance can be further increased. It is also conceivable and possible, for example, for the two brushes 5 mounted on a pressing brush holder 40 or on the supporting brush holder 50 to be driven by a common motor 36 and a corresponding distributor gear.
    The illustrated in Figs. 11 to 13 second embodiment of a floor cleaning device 1 according to the invention differs from the first embodiment in terms of the type of suspension of the brush device 20 on the suspension unit 10 and the initiation of the thrust forces to move the brush device. Apart from the still to be explained below
    Differences from the first embodiment corresponds to the embodiment of that of the first embodiment and reference is made to the description of the figures for the first embodiment.
    The axle unit 22 is movable in the second embodiment both in the vertical and in the horizontal direction relative to the suspension unit 10. The guide pins 23 pass through a window recess 17 of the suspension unit 10, cf. 11 to 13. The thrust members 11 of the suspension unit 10 are formed here as separate parts and act in the working position the brush device 20 for movement in the direction of travel 3 against opposite to the direction of travel 3 directed surfaces 26 of the brush device 20. The thrust members 11 are below the height the pivot axis 13 is arranged. In contrast to the first embodiment, the suspension unit 10 thus does not interact with the axle unit 22 to transmit the thrust.
    The thrust members 11 are conveniently adjustable in height relative to the thrust member 11 supporting part of the suspension unit 10. This is not shown separately in the figures. In particular, due to the different soil conditions or coefficients of friction of the substrate 2 and the frictional forces acting thereby can be equalized by a height adjustment, the torque acting through the friction about the pivot axis 13. By a corresponding arrangement of the thrust member 11 at a certain height, depending on the friction conditions occurring a corresponding counter-torque can be adjusted. In this case, the force member 14 can be conveniently unlocked, d. H. that in the working position no additional torque from the lifting unit 10 to the axle unit 22 about the pivot axis 13 must be exercised. However, it is also conceivable and possible, even in the second embodiment, to use the lifting unit 14 for exerting a torque about the pivot axis 13.
    In the passive position both guide pins 23 are on a window recess 17 upwardly bounding wall, see. Fig. 13. The
    Force member 12 may in this case, in contrast to the working position, be controlled so that it moves into a retracted position and the axle unit 22 holds above.
    Also in the second embodiment, it is provided that the guide pin 23 in the working position of the brush device 20, which occupies this when cleaning a horizontal surface 2, seen in the vertical direction is arranged centrally between the limiting walls of the recess 17 of the suspension unit 10. The thrust member 11 allows in the second embodiment, an adjustment of the position of the brush device 20 relative to the vehicle 4 seen in the direction of travel 3, by the variation of the length of the thrust member 11, which is shown in the embodiment as an adjusting screw.
    In the second embodiment, it is provided that the lifting member 14 is supported at a different location on the vehicle than on the suspension unit 10. The force member 12 is supported at a different point of the vehicle on the vehicle. It is of course conceivable and possible for the lifting member 14 and the force member 12 to be supported on the suspension unit 10 analogously to the first exemplary embodiment.
    The direction of travel 3 shown in the figures refers to a straight ahead travel of the vehicle 4. Other directions of travel, e.g. when driving on bends are possible. Also, a reverse drive against the marked direction of travel 3 is conveniently at least at a slow pace possible, possibly with reduced cleaning performance. In the first embodiment, in this case, the guide pins 23 at the front part of the respective elongated hole 15 at. In the second embodiment, the thrust force in a reverse drive in the region of the axle unit 22 must be initiated.
