With the help of the auxiliary actuators back the gear surface from between moves, the transfer bar is obtained locking the transfer rollers, which last stretch. The displacement roller pairs are advantageously articulated with vertical axes and the displacement rollers included in each other. width. at a distance from the displacement rod's displacement roller pair is The distance determined by The displacement roller pair can be stored in rolling bearings.
    According to one application, the transfer roller pairs are made of polyurethane rubber. In this way, the transfer roller pairs become easily compressible and gripping, but still durable.
    Advantageously, the joint between the transfer bar and the gear unit comprises a horizontal recess and between the transfer bar and the gear unit an actuator is further included for moving the transfer bar in relation to the gear unit. The actuator assists the transfer bar between the transfer rollers.
    According is articulated in an application bottom. The shift bar of the swap body Thanks to the joint, the truck and the trailer can stand at a certain angle to each other, since the articulated transfer bar corrects the position of the swap body when the swap body goes over on the truck.
    According to another application, the displacement mechanism on the trailer chassis with vertical joints comprises articulated displacement roller rods for enabling the horizontal movement of the displacement roller pair and transverse to the longitudinal direction of the gear unit, each displacement roller bar having a first end and relative to the joint are articulated. With the aid of the transfer roller bars, a permanently mounted transfer bar can be used in the bottom of the gear unit, since the transfer roller bars enable the movement of the transfer rollers laterally according to the location of the transfer bar. According to one application form, the device comprises an inductive sensor located at the end of the trailer against the truck for detecting the truck. With the help of the sensor, the rotation of the transfer rollers can be started when the gear flat is sufficiently close to the transfer mechanism, and the transfer rollers do not have to be rotated unnecessarily.
    According to one embodiment, the device comprises displacement roller motors for rotating the displacement roller pairs, which roller motors are parallel-connected gerotor motors. A gerotor motor can be remarkably small in relation to the torque obtained from it.

The movement of the gear unit 16 is performed by means of a 3a - 4 15.
    The displacement mechanism 15 comprises a displacement rod 28 shown in the figures, a displacement mechanism arranged to be attached to the bottom of the gear unit 16 and at least two displacement roller pairs 20 and 22 fixed in connection with the chassis 30 of the trailer 12 at a distance from each other for pulling the displacement rod 28 by friction. With others, slide the transfer bar by means of friction between the transfer roller pairs. Furthermore, the pairs 21 of each displacement roller 20 and 22 are spaced 21 apart. The distance between the rollers 21 and 22 of the first and second displacement roller pairs 20 and 22 relative to each other is a few millimeters smaller than the thickness of the displacement rod 28.
    The mutual distance or spacing of the displacement roller pairs 20 and 22 is shorter than the length of the displacement rod 28, so that the displacement rod 28 is always pulled by at least one of the displacement roller pairs 20 and 22. The displacement rod can also be a displacement rail or a corresponding rod-like body.
    A device 10 according to the invention is described in more detail in connection with Figures 1 - 5b. When moving the gear surface 16 from the truck 14, the truck 14 is backed close to 12 89. The front end of the trailer chassis 30 and shown in Figure 5b is the truck end of the trailer. By means of the guide pins 36 and the guide bushings 38, a power transmission means 31 included in the power transmission arrangement of the truck 14 is attached to the trailer 12, the power from the hydraulic motor 34 of the truck 14 being led to the power receiving means 33, the hydraulic pump 32 of the trailer 12.
    The hydraulic pump 32 produces pressure for the hydraulic system 48 shown in the trailer 12 shown in Figure 6, by means of which the hydraulic system 48 By means of the auxiliary actuators 48, which push the workers included in the gear surface 16 of the pressure, the hydraulic system drives the locking pins over its abutment and thereby releases them in figures 3a 3b 26. the auxiliary actuators 24 continue to push until they are in the gear flat 16 and shown the hook hooks Hereinafter the rail wheels (not in the figures) are lifted from the rails 30 of the trailer 12 chassis The auxiliary actuators may be initial sliding cylinders known from the prior art, which project on the gear surface from its rear end.
    At the same time, the hydraulic system 48 drives the displacement roller motors 54, which in turn drive the displacement roller pairs 20 and 22.
    When the gear flat 16 rises on the rails 40, the end rod 28 of the transfer bar 28 guided in the bottom of the gear bed 16 goes between the rollers 21 of the first moving roller pairs 20, which begin to pull the moving rod 28 and thus the gear flat 16 towards the second moving roller pair 22. In one phase of the movement end to the rollers of the second moving roller pair 22, which begin to pull the moving rod 28 together with the first moving roller pair 20. The gear surface 16 moves closer to the truck 14, the moving rod 28 departing from between the first moving roller pair 20 and the second moving roller pair 14 on the moving roller pair 22.
    When moving cassette gear unit 16 back to the trailer 12, a hydraulic or pneumatic actuator, in this case a brake bell 94, gear unit 16, which is to be cassetteed from the truck 18 platform 18 back to 12 range, is advantageously attached to the end 18 of the truck 14. This means that the brake bell 94 pushes the gear flat 16 should until the function of the brake bell 94 is to push on the moving mechanism of the trailer being cassette, its moving rod of the moving mechanism comes iJ1 between the moving rollers which pull the gear flat 16 on the trailer 12 UP.
    Figure 3a shows a chassis 30 of the trailer 12 seen from above in an arrangement according to an embodiment of the invention.
    The arrangement is very simple in relation to the state of the art. Only the displacement roller pairs 20 and 22, the displacement roller motor 54, the hydraulic system 48 (shown in Figure 6), the auxiliary actuators 24 and the locking hooks 26 are attached to the chassis 30. The auxiliary actuators 24 are attached to the chassis by means of the brackets 27. an arrangement according to the invention be as much as 500 - 1000 kg lighter than an equipment according to the prior art. In addition, an arrangement according to the invention can be mounted on a standard trailer.
    Figure 3b shows an arrangement according to another embodiment, where the transfer rollers 21 are articulated via the transfer roller rods 90 to a fitting 88 which is included in the chassis 30 of the trailer 12. In this case the transfer rod in the bottom of the gear unit can be fixedly mounted, since the joint 92 rotates 90. enables it to move the moving roller pairs 20 and 22 relative to the transverse movement of the gear unit in the horizontal plane of direction of movement. In this way, the transfer roller pairs 20 and 22 adapt to the transfer bar, if the transfer bar is slightly on the side of the center line. In the images of the arrangement seen from the side, an arrangement according to the application form is shown in Figure 3a.
    Figures 5a and 5b show an end of the chassis arranged in the movement mechanism on the load bed 18 of the truck and its equivalent on the trailer 30. The included power transmission arrangement of the truck includes a power transmission arrangement of the arrangement and a primary motor 34 d. a hydraulic motor 34, a power transmission means 31 located in the rear end of the truck 14 and a mechanical contact with each other placed on the trailer 12. 31 33 by reversing 14 rear end 12 The arrangement 10 further comprises a force receiving means with the front receiving means 33 on the trailer 33. . 12 of the displacement mechanism 15 of the truck placed against the trailer of the trailer.
    When using a movement mechanism 3a advantageously articulated. to the gearbox to according to 28 The joint can have the application form in figure, the transfer rod 16 is the bottom. made the same point of the gear unit in wheels. longitudinal direction as the last of the gear unit Due to the joint, the truck and the trailer do not have to be completely in line with each other, since the articulated moving rod corrects the gear unit This position, when the gear unit is moved to the truck. considerably facilitates the movement of the gear unit.
    The end of the transfer bar 28 against the truck 14 has been advantageously made wedge-shaped, which makes it easier for the transfer bar 28 to enter between the transfer roller pairs 20 and 22.
    The transfer bar is preferably steel-blown, so that its surface is rough to obtain the necessary friction.
    The transfer bar is advantageous in its length 50 - 90%, advantageously 60 - 80% of the length of the gear unit.
    According to one embodiment, the transfer rollers 21 and 22 of the transfer roller pairs 20 and 22 may be made of polyurethane rubber or equivalent material suitable for the purpose of use. In the transfer mechanism, the transfer roller pairs may be two or more. Polyurethane is a suitable material because it can be compressed slightly, whereby sufficient friction is obtained between the transfer rod and the transfer rollers. In addition, the polyurethane 10 is sufficiently hard to withstand the load to which it is subjected.
    An application form of the arrangement according to figure 4 comprises the locking devices 16 of the gear unit 16 placed on the trailer 12, which 26 locking resistors. is advantageous recess in locking devices further comprises locking hooks and locking brackets 42. the rails. With the aid of the locking brackets, the gear unit can be locked on the trailer during transport, so that the transfer rod, which is not located between the transfer rollers, the material of the transfer rollers can return to the resting state.
    The arrangement 10 includes advantageous auxiliary actuators 24 attached to the chassis 30 of the trailer 12 for sliding the gear surface 16 from the locking abutment 42 to the rails 40. The auxiliary cylinders are advantageously hydraulic cylinders. The displacement roller pairs 20 and 22 are advantageously mounted with roller bearings, so that the gear surface 16 is extremely easy to move on the rails 40. In prior art equipment, plain bearings are generally used, so the forces used in an arrangement according to the invention are less than for prior art equipment.
    Figure 6 shows a favorable alternative to a hydraulic system 48 according to the invention. In 48 32, the hydraulic system force pumps a hydraulic pump which gets its from it in the truck pressure to the hydraulic system 48 actuator. 32 the pressure filter 60 the auxiliary actuators 24, from which the oil goes to the contrast valve 64, back to 66. the hydraulic system 48 further comprises a sequence valve 58 and a 59 provided the auxiliary actuators 24 advantageously used cylinders go to the bottom Favorable with its choke leak line. When a pressure peak arises, which opens the sequence valve 58. In this case the supply is controlled via the two-sided relief valve 50 for the load to the flow distribution valve 52, where the flow is divided equally between the parallel-connected transfer roller motors 54. In the open position resistance.
    The sequence valve 58 closes when the pressure line goes to depressurization.
    Via the choke 59, a small volume flow always goes to the transfer roller motors 54, so that the transfer roller motors 54 creep forward when the end of the transfer rod reaches the transfer rollers.
    The distribution valve 52 may be e.g. a gear distributor or a pressure compensated cartridge valve.
    The displacement roller motors 54 can advantageously be 1/6-speed gerotor motors or other motors suitable for the purpose, with which a large torque can be achieved with small motor speeds. The transfer roller motors can also be connected in series, but when connecting in parallel, the motors' housing pressure is kept lower. 54 double-sided discharge valve 50 for the load and further back to the oil container 66.
    From the transfer roller motors, the oil returns to it On the pressure side of the hydraulic pump 32 there is advantageously a pressure-controlled locking valve 56, to the oil container 66. back to the trailer, through which the oil can be released. Since the amount of oil on the pressure side is so much larger that it corresponds to the volume of the piston rod of the cylinder, than the volume on the return side, the locking valve 56 is needed, which releases the excess oil past the pump 32.
    The transfer roller motors are connected in parallel when the gear unit is moved to the trailer. With the aid of the parallel coupling, the rotation of the displacement roller pair can be stopped when the displacement rod is not between the displacement roller pairs. When the truck is reversing towards the trailer, an inductive sensor detects the truck as it is close enough to the trailer. In this case, the hydraulic valve 62 is closed and the pressure of the hydraulic system is controlled to the displacement roller motors, which begin to rotate the displacement roller pairs. When again a gear unit is moved away from this truck and the truck is driven, the trailer detects the inductive sensor and opens the hydraulic valve 62, whereby the function of the transfer roller motors stops.
    When moving gearboxes back to the trailer, the transfer roller motors can be depressurized, whereby they rotate freely. Alternatively, the transfer rollers can be rotated so that the movement of the gear unit back to the trailer chassis is assisted as in Figure 2.
    Figure 7 shows an actuator 45 which is attached to the bottom of the gear unit 16 and at its other end to the transfer rod 28, i.e.
    The nut 44 of the rod cylinder 45 is attached to 46. The displacement rod 28 may in turn be the rod cylinder 45. The displacement rod 28 is articulated to the bottom 51 of the gear barrel 16 by means of the hinge shaft 49 and in which the bottom barrel and piston rod of the coupling is an elongate recess 47. the displacement rod 28 moves relative to the swap body 16. The displacement rod 28 can thus rotate slightly relative to the longitudinal direction of the platform and move in the longitudinal direction as much as the recess 47 allows. The clearance can be 10 - 300 mm, preferably 50 - 100 mm.
    When the gear unit is locked by means of the locking brackets 42, the transfer rod 28 is not present between the transfer roller pairs. In this way, the transfer rollers material cannot be compressed against the transfer bar 28, if the same gear unit is locked for a long time on the trailer. The function of the rod cylinder 45 is to push the end of the displacement tongs 28 against the first displacement roller pair 20 when the gear surface 16 lies on the locking abutments 42. In this case, the displacement rod will immediately end up between the pulling displacement roller pairs 10 when the auxiliary actuators start firing. In addition, the bar cylinder acts as a means of damping movements, which dampens abrupt stops during the movement of the gear unit. The rod cylinder 45 can e.g. be a hydraulic cylinder. During the movement of the gearbox, the bar cylinder collects pressure to a pressure accumulator connected by means of dampers or control valves, with the power of which the bar cylinder operates.
    According to an application form, the arrangement can also be placed on a semi-trailer, which has two platforms inside each other. In this case, the tiltable platform is wider and the gear unit the platform. inside the tippable According to one application form, there are teeth on the side of the transfer bar which are included in the transfer mechanism and the transfer rollers are gears.
    According to the I a a favorable application of the arrangement, the trailer drawbar used is a telescopic drawbar. arrangement according to the prior art, the trailer is detached from the cassette flat combination when it arrives at the tipping point, the truck tips its load and picks up the cassette from the trailer. When the trailer is detached from the truck, the drawbar is released from the coupling and lowered to the ground. When the trailer's cassette is retrieved, the truck tilts close to the trailer's chassis, with the drawbar partly ending up under the rear wheel axle of the truck. A drawbar on the ground is exposed to dirt and requires a separate work effort after unloading the load, when the trailer is to be reconnected to the truck.
    With an arrangement according to this advantageous form of application, a better usability is obtained than in the state of the art, when the truck does not have to drive away from the trailer during the time of lifting the drawbar. A lifting device for the trailer's drawbar also becomes superfluous, which simplifies the arrangement.
    With this arrangement, it is easier to cassette cassette changers, since the telescopic drawbar together with the towing coupling locks the trailer's front trailer in the same direction as the truck. The truck and trailer can also be put in a so-called locking. An empty cassette tray combination can be run shorter, making it easier to handle. In an arrangement according to the application form. For example, the telescopic drawbar can always be kept in the air, keeping it cleaner, which makes it possible to grease the drawbar eye and drawbar coupling. nowadays often in trucks In addition, there are steerable rear bogies, which have air suspension. The air suspension bellows are often placed in solutions according to the state of the art just at the traction coupling, whereby they limit the position of the traction coupling and the traction coupling must be placed under the air bellows. Further down, however, the traction coupling is more exposed to dirt and contaminants.
    In an arrangement according to a favorable form of application, the towing coupling of the truck has been placed adjacent to the chassis beams of the truck. It is possible to place a towing beam of a truck and thus the towing coupling between the chassis beams of the truck protected against tipping situations, whereby the overhang of the tipping hinge and the location of the towing beam can be chosen more freely. In addition, the traction coupling is obtained higher than with solutions according to the prior art, in protection from soiling.
    Advantageously, the arrangement uses a standardized underrun protection at the rear of full width for trucks, since the cassette trailer's drawbar does not go under the truck in any situation. A construction according to the application form enables it to be possible to select the overhang of the truck's tipping hinge and the position of the drawbar independently of the suspension.
    Figures 8 - 11 show in more detail the construction and phases of use of this advantageous application form. According to Figure 1, the trailer 12 of the arrangement 10 is attached to the truck 14 with a telescopic drawbar 70. The telescopic drawbar 70 may be attached to an attachment point 75 below the chassis 30 of the trailer 12.
    Advantageously, a telescopic drawbar 70 includes the arm 74, a mounting structure (not in the figure), a towing eye 78 and pneumatic and power lines 72. The pneumatic and power lines 72 coming from the trailer 12 can be pulled according to the figure under the telescopic drawbar 70 and attached at fixed intervals. on a rod 76 under the arm 74 so that they can be compressed when the telescopic drawbar is pushed in. In this case, the lines can be made without line movers (line throwers) according to the state of the art, which operate quite uncontrolled and often soil the towing eye of the towing eye. 78 in down pipes and contacts in dirt The telescopic drawbar 70 is fastened by means of the tow coupling 68. of the truck 148. The locking of the telescopic drawbar is advantageously air-driven, since compressed air is available in the trailer.
    Figure 8 shows the operation of a cassette barge combination telescopic drawbar 70 according to the application form, when the bed 16 of the trailer 12 begins to be moved to the truck 14. When the truck 14 is backed against the trailer 30 of the trailer 12, the telescopic drawbar 70 is pushed under the trailer 12 chassis 30. the telescopic drawbar 70 extends from the end of the chassis 30 of the trailer 12 towards the truck to the rear of the front wheel axle 80 of the trailer 12. Above the front wheel axle 80 there is advantageously a collar, through which the telescopic drawbar 70 runs. When the truck is reversing, the telescopic drawbar is constantly attached to the truck's drawbar coupling. The pneumatic and electric lines 72 are compressed in this position. The trailer shown in the figure is in position for road driving, whereby it is slightly lower than in the cassette position. In this context, a telescopic drawbar means a drawbar which moves in relation to the trailer's main wheel axle in the longitudinal direction of the trailer when pulling out or pushing in. A telescopic drawbar can in itself be a fixed rod, but its movement at the front wheel axle of the trailer causes the distance between the trailer and the towing vehicle to decrease when the telescopic drawbar is constantly attached to the towing coupling of the towing vehicle. The movement of the telescopic drawbar in relation to the main wheel axle of the trailer can be effected by means of a towing vehicle, when the telescopic drawbar is attached to the towing coupling of the truck.
    Figure 9a shows the telescopic drawbar 70 of the arrangement in the extended position, when the trailer 12 is without a truck. Figure 9b shows the same situation when the telescopic drawbar 70 is in the retracted position.
    In this application form. of the arrangement, the space required in the longitudinal direction of the trailer is less than in solutions according to the prior art. When parking a cassette flat combination, its necessary longitudinal space is shorter, as the carcass of the truck and trailer can be driven against each other during parking. In addition, an empty vehicle combination can be driven with a shorter length of the telescopic drawbar, making it easier to handle the vehicle crew.
    An arrangement according to the application form can be carried out without the telescopic drawbar 70 lying on the ground or taking up space in front of the chassis 30 of the trailer 12. In this case, the towing eye 78 of the telescopic drawbar 70 also remains in the air at all times.
    The telescopic drawbar can always be above the ground, whereby the pneumatic and power lines remain clean and also the drawbar of the telescopic drawbar is kept clean. This also enables the drawbar eye and the drawbar coupling to be greased, whereby an annual replacement of wear parts can be avoided. often performed The relocation of the towbar end of the drawbar according to the prior art also becomes unnecessary with a solution according to this form of application. Lifting equipment for the trailer's drawbar also becomes unnecessary and the truck does not have to be driven free from the trailer during the lifting of the drawbar, nor can the drawbar to be lifted scrape the bottom of the truck as in prior art solutions. In addition, with a solution according to the arrangement, it can be avoided to collide with a drawbar resting on the ground when reversing the truck towards the trailer.
    According to Figure 8, the front pairs of wheels of the trailer 12 may be smaller than the rear ones. On top of the pair of wheels' wheel axle 80, there will be an empty space for the position of the brake bells, The arm 74 of the telescopic drawbar 70 can be slid over the wheel axle 80 under the chassis 30 of the trailer 12. In the application form with the truck cassette surface combination 14 in Figure 1 shows a tipping position. In prior art solutions, the tilt shaft must be placed further back on the chassis of the truck, as the air bellows of the air suspension have limited the position of the drawbeam. According to this application form, the telescopic drawbar ends up so high in the trailer that it enables mounting of the truck 14's drawbeam and towing coupling 68 above the truck's thanks to which the Flake's air suspension bags, between the chassis beams, the towing coupling 68 are protected in the tipping situation. The tilting axle can be in the optimal position later on when the truck's chassis is placed, the bellows of the air springs do not interfere with the position of the drawbar. The location of the drawbar 68 is shown in more detail in Figure 11.
    Thanks to the favorable location of the traction coupling, according to Figure 11 it ends up higher than in solutions according to the state of the art, protected from load from the bed and other dirt. In addition, thanks to the higher-lying drawbar coupling, the telescopic drawbar is horizontally almost horizontal, the forces directed at the drawbar coupling during drawing not significantly tearing the drawbar coupling. According to the figure, the overhang 86 of the truck's tilt hinge 84 and the location of the drawbeam can be selected independently of the suspension. The figure also shows a rear underrun protection 82. 10 l5 20 25 30 35 »as l9 The mounting structure of the telescopic drawbar An arrangement according to the application form can e.g. be an A-buck. Between the A-bar and the bar of the telescopic drawbar there is an equipment with which the bar of the drawbar is locked to the A-bar. The A-buck can also be made a mirror image and the construction can be placed under the trailer's front trailer. In this case, the attachment points in the trailer's chassis end up further away. Here, the front trailer refers to the part of the trailer to which the wheel axles of the trailer closest to the truck are attached. The attachment structure can also be a structure that replaces the A-bracket, which is suitable for use in the construction of a trailer. From the state of the art, a TRAKO drawbar from the Finnish manufacturer TMT-Malinen Oy is known, which is an example of a solution for the fastening construction.
    In this context, a solution is presented, in which there is a combination of automatic drawbar coupling and telescopic drawbar in the truck as follows, which can also be used independently of the gearbox movement mechanism in any gearbox configuration. In this solution, the trailer comprises a telescopic drawbar, the for example of which constructions 2 and 8 - 11, used in the truck can be an automatic draw coupling. One of these is shown in Figures 1, and the traction coupling as an automatic traction coupling is the automatic traction coupling manufactured by the Swedish manufacturer VBG GROUP Ab with the product name MFC (Multi-function coupling), where the attachment of the drawbar and the coupling of hydraulic, pneumatic and power lines are driven automatically via the traction coupling. . Then e.g. the automatic traction coupling from the truck to the trailer is conveyed via the required hydraulic power via the required hydraulic force, whereby mechanical power transmission devices between trucks and power transmission devices have been described, for example in publication FI 88008 B, trailer unnecessary. Such mechanical displacement devices operating with hydraulic cylinders in this solution can be applied using the energy conveyed via the automatic traction coupling. Advantageous moving devices have been described in the publications FI 88008 B and EP 1487666 B1.
    An automatic drawbar coupling is particularly advantageous to use together with a telescopic drawbar, as the automatic drawbar coupling can here be placed high between the chassis beams of the truck, where the drawbar fits in the * shifting situation of the gearbox between the truck and the trailer. This is especially important when using automatic traction couplings, as these are not very resistant to dirt. Therefore, an automatic drawbar coupling cannot be placed close to the ground, and an ordinary drawbar that is laid on the ground easily soils the drawbar coupling and the connecting components of the drawbar. An automatic traction coupling construction soul is described in SE 1777084 and SE 1914094. may be equivalent to the 1710145, in the publications EP
