    SUMMARY The invention relates to a device (299) in vehicles for distributing Lubricant from a lubricant bath (205) arranged in a gear housing (210) to a rotatable cover (240) and again, where a shaft driven via a crown wheel (215) (260) runs between the housing (210) and the housing (240) and where lubricant is arranged to be transferred from said bath (205) to distribution means (220, 280) by means of the crown wheel (215). The distribution means (220, 280) comprise a sleeve (280) arranged around the shaft (260) and running in a shaft pin (230) for a drive wheel (261; 262). The sleeve defines spaces (P2, P3) between the drive shaft (260) and the surrounding shaft journal (230), which spaces (P2, P3) participate in the distribution of the lubricant from said bath (205) to the housing (240) and back. The invention also relates to a motor vehicle (100; 110) equipped with the timing device (299). Figure 3a for publication

    15 20 25 30 wiper is mounted to the shaft pin and presently arranged in the housing.
    The wiper includes a paddle that wipes oil from the inside of the rotating cover. The scraper also comprises a passage which is arranged to lead the stripped oil to the shaft pin. The shaft journal is configured to guide the oil supplied from the wiper back to the oil bath in the gearbox housing.
    The device described above for distributing oil in a motor vehicle today works satisfactorily. However, it is associated with certain shortcomings, as will be described below.
    Due to the fact that the oil pipe that is configured between the gear housing and the housing runs in a space in the shaft journal, it is difficult to be able to modify the dimensions of the drive shaft. In some cases it is desirable to have a drive shaft which has a larger diameter than the dimensions currently in force. By having a drive shaft that has a larger diameter, properties such as e.g. reduced driveline oscillation of the vehicle during operation is obtained. Today's vehicles that have drive shafts with a smaller diameter can be perceived by a driver to have a slightly lesser comfort than a vehicle that has drive shafts with a larger diameter.
    In addition, vehicles having larger diameter drive shafts can obtain improved torque transmission performance in the vehicle's powertrain.
    A possible solution to dealing with the disadvantages described above may involve arranging a flattened oil pipe running between the gear housing and the housing. In this way, a larger space is obtained in the shaft journal which makes it possible to implement a drive shaft of larger dimension. However, tests have shown that the oil flow in the oil pipe is negatively affected to an excessive extent for this solution to be attractive.
    Another way to provide an opportunity to implement a drive shaft of coarser dimension could be to modify the shaft journal. If the axle pin itself were to be modified, a number of surrounding components of the vehicle would also need to be relocated or modified. However, this entails large development costs.
    Thus, there is a need to provide a device for distributing oil to the driving axles of motor vehicles, which makes it possible to increase the dimensions of the drive axles without appreciably affecting the oil flow and requiring modifications to the axle pin.
    US 5,535,850 discloses a device for a drive shaft of a vehicle having a circulation system for a lubricant. The circulation flow of the lubricant is driven by a costly oil pump, which is arranged between a gear housing and a planetary gear.
    SUMMARY OF THE INVENTION An object of the present invention is to provide a new and advantageous device for distributing lubricant at a driving wheel axle of a motor vehicle.
    Another object of the present invention is to provide a device for distributing lubricant which enables efficient transfer of lubricant between a central gear lubricant bath and a planetary gear located at the motor wheel of the motor vehicle without requiring a modification of an axle pin present therebetween.
    A further object of the present invention is to provide a robust device for distributing lubricant to the driving axle of a motor vehicle.
    These objects are achieved with a device for distributing lubricant in a motor vehicle according to claim 1. According to one aspect of the invention, a device is provided at the wheel axle for driving a vehicle for distributing Lubricant from a lubricant bath arranged in a wheel axle existing gear housing to a rotatable housing arranged at the drive wheel of the vehicle and again, in which gear housing a crown wheel via a differential drives a drive shaft which runs from the gear housing through a shaft pin arranged to the gear housing to a gear present in the housing and where lubricant is arranged to be transferred from said bath to distribution means by means of the crown wheel, said distribution means comprising said sleeve arranged around the shaft and running in the shaft journal, which sleeve delimits spaces between the drive shaft and the surrounding shaft journal, which spaces participate in the lubricant distribution from said bath to the housing and back.
    This advantageously enables lubricant to be conducted in a space between the drive shaft and the sleeve, which means that a part of the oil line pipe which according to known technology ran between the gear housing and the housing can be removed.
    In an embodiment of the invention, the lubricant is of course transferred by gravity from the lubricant bath to the housing. This means that a pump, such as e.g. that described in the prior art (see US 5,535,850), is not required. The device according to an invention thus constitutes a cost-effective solution to the above problems.
    The device is easy to implement in existing motor vehicles. In cases where a new drive shaft with a larger diameter is installed in a motor vehicle, the innovative device can also be installed. The installation of the device according to the invention is simple and thus cost-effective.
    The device for distributing lubricant according to the invention can be installed in the vehicle during manufacture thereof. A buyer of the vehicle can thus have the opportunity to choose a vehicle with coarser drive shafts and associated device for distributing lubricant as an option. The distribution means makes it possible to guide the lubricant in a space between the sleeve and the shaft to the cover. In this way, an efficient transfer of the lubricant from the lubricant bath to the housing and back can be achieved.
    The sleeve can be arranged to externally guide the lubricant from the cover. The sleeve thus has several functions. The sleeve can thus function as a carrier of the lubricant. By the sleeve together with the surrounding shaft pin back to the closed circulation system for the lubricant, which makes unnecessary additional components can be used to guide the lubricant from the cover the lubricant bath provides a device with one and results in a cost effective solution to the above problems.
    The lubricant is preferably an oil, such as lubricating oil or alternatively a lubricating emulsion. The invention is not limited to any particular type of lubricant but various suitable lubricants may be used.
    A tube can be arranged to catch lubricant vomited by the crown wheel and to lead the lubricant into the sleeve through an opening of the sleeve. The tube may be provided with an inlet, such as a slot, for receiving oil vomited from the crown wheel. The pipe can advantageously be made of plastic and thus constitutes a relatively cheap component, which means that a cost-effective solution to the above-mentioned problems is achieved. The pipe can have an arbitrary configuration and can thus be fitted in a manner that is suitable considering the geometry of adjacent components. By introducing lubricant into the sleeve through an opening of the sleeve, a simple configuration is achieved. An opening, such as e.g. a circular through hole, of the housing for receiving the tube leading the lubricant can be formed in the manufacture of the sleeve. This results in easy installation of the device for distributing lubricant as a reduced number of mounting steps are required for an installer. 10 15 20 25 30 The sleeve is provided with an end element, which prevents an incorrect flow of the lubricant. The end element is arranged to counteract or completely prevent Lubricant from flowing out of the space between the sleeve and the drive shaft in an incorrect manner, such as e.g. at one end of the sleeve facing the gear housing. In this way, a device is provided for distributing lubricant which has an efficient and desirable flow from the gear housing to the housing. The end element can have an arbitrary configuration so that it completely or partially covers at least the lower part of the end of the sleeve towards the gear housing.
    In an alternative embodiment, the pipe which is arranged to catch lubricant vomited by the crown wheel can lead the lubricant into the sleeve through the end element which is facing the gear housing. This provides an alternative configuration of the device for guiding lubricant from the central gear housing to the planetary gear, which is housed in the housing of the vehicle's drive wheel. An opening, such as e.g. a circular through hole, can be easily made in the manufacture of the end element to receive the tube leading the lubricant. This enables a simple installation of the device for distributing lubricant during the wheel axle assembly.
    The device for distributing lubricant may further comprise a scraper which is arranged to catch lubricant of the rotating cover and guide the lubricant to an outside of the sleeve. The scraper comprises a vane fixed to the shaft journal, the position of which can be set in advance. The position of the blade determines the maximum thickness of the lubricant film formed on the inside of the housing as it rotates during operation of the vehicle.
    The wiper thus provides the effect of regulating a flow of lubricant in the device for distributing lubricant in a predetermined manner.
    The scraper also includes a passageway which is arranged to guide the lubricated lubricant from the paddle to the outside of the sleeve. The device may further comprise a second end element to prevent an incorrect flow of the lubricant. The second end element is arranged to counteract or completely prevent lubricant from being incorrectly transferred at the end of the sleeve facing the housing. Due to the presence of the second end element, the flow of the lubricant is controlled in a direction towards the lubricant bath in the gear housing so that lubricant from the wiper is prevented from being returned directly to the housing. In this way, a device is provided for distributing lubricant which has an efficient and desirable flow.
    The sleeve can be fixedly mounted in the axle pin and advantageously be arranged eccentrically relative to a drive shaft of the vehicle, which in addition to providing a robust construction facilitates the flow of lubricant through the spaces delimited by the sleeve relative to the axle pin and the drive shaft.
    The device may comprise a pump element placed in a space between the sleeve and the drive shaft. The pump element can increase the fatal speed of improving The pump element can be a spiral wound around the drive shaft. Then the lubricant and thus the efficiency of the device. the drive shaft rotates, the coil will increase the flow of the lubricant. The spiral can consist of plastic and thus be a cheap component.
    The above objects are also achieved with a motor vehicle which includes the features of the device as set out in claims 1-12.
    The motor vehicle can be a truck, a bus, a wheel loader or a construction vehicle.
    An advantage of the innovative device for distributing lubricant in the drive shaft of a motor vehicle is that a self-regulating effect is obtained. When the vehicle is driving slowly, there is a large amount of lubricant in the bottom of the cover. When the vehicle is driven faster, lubricant flows to some extent back to the lubricant bath, which is desirable because the friction of the planetary gear would otherwise be too great. Additional objects, advantages and novel features of the present invention will become apparent to those skilled in the art from the following details, as well as through the practice of the invention. From the description of the invention below, it should be apparent that the invention is not limited to the specific details described.
    Those skilled in the art having access to the teachings herein will recognize additional applications, modifications, and incorporations within other fields which are within the scope of the invention. SUMMARY DESCRIPTION OF THE DRAWINGS For a more complete understanding of the present invention and further objects and advantages thereof, reference is now made to the following detailed description which is to be read in conjunction with the accompanying drawings in which like reference numerals refer to like parts in the various figures, and in which: 1a schematically illustrates a vehicle, according to an embodiment of the invention; Figure 1b schematically illustrates a subsystem of the vehicle shown in Figure 1a, according to an embodiment of the invention; Figure 2 schematically illustrates an apparatus for distributing lubricant to the vehicle shown in Figure 1a, according to an embodiment of the invention; Figure 3a schematically illustrates in further detail a part of a device for distributing lubricant of the vehicle shown in Figure 1a, according to an embodiment of the invention; and Figure 3b schematically illustrates in further detail a part of a device for distributing lubricant of the vehicle shown in Figure 1a, according to an alternative embodiment of the invention.
    DETAILED DESCRIPTION OF FIGURES 10 Referring to Figure 1a, a side view of a vehicle 100 is shown. The exemplary vehicle 100 consists of a tractor 110 and a trailer 112.
    The vehicle can be a heavy vehicle, such as a truck or a bus. The vehicle may alternatively be a wheel loader or a construction vehicle, such as e.g. and shaft shaft.
    Referring to Figure 1b, a subsystem 199 of the vehicle 100 is shown.
    The vehicle 100 is motor driven and includes an internal combustion engine 150 and a driveline for transmitting a torque from the engine 150 to the drive wheels 261, 262 of the vehicle 100. The torque is arranged to be transmitted via a gearbox 160 and a PTO shaft 170 to a central gear 212. The central gear 212 comprises a crown wheel and a differential to which two drive shafts 260 are connected. The drive shafts 260 each drive drive wheels 261 and 262, respectively.
    The vehicle 100 can be equipped with any number of driving wheel axles.
    According to one embodiment, the motor vehicle can be a so-called 6x4 vehicles, i.e. a vehicle that has six driving wheels of which four are driving, ie a total of three wheel axles, two of which are driving. The vehicle shown in Figure 1b is of the 4x2 type. Two non-driving front wheels of the vehicle 100 have thus been omitted from Figure 1b.
    Referring to Figure 2, there is shown an apparatus 299 for distributing lubricant at the wheel axle shown of the motor vehicle 100 shown in Figure 1a. The device 299 is arranged in the tractor 110. Figure 2 shows only a device 299 for distributing lubricant at a drive shaft 260. It is obvious to a person skilled in the art that two drive shafts start from the central gear 212 to a respective gear at opposite drive wheels. The lubricant bath 205 is common to both drive shafts, such as e.g. the drive shafts 260 shown in Figure 1b.
    The device 299 comprises a central gear 212 arranged in a gear housing 210 having a lubricant bath 205 at the bottom thereof. A shaft journal 230 is fixedly arranged at the gear housing 210 and carries via roller bearings a rotatable cover 240 which in turn is attached to a drive wheel (not shown). The housing 240 forms part of a piano gear which is only schematically represented in Figure 2, which in a known manner transmits driving force from a driving shaft 260 to the driving wheel. The drive shaft 260 is arranged in the gear housing 210 and the shaft journal 230 and transmits torque between the central gear 212 and the drive wheel via the pianist gear present in the housing 240. A lubricant tube 220 is provided in the gear housing 210 and has an opening 225 for catching lubricant which is thrown up by a rotating crown wheel 215 which is in contact with the lubricant in the lubricant ice bath 205 in the gear housing 210.
    The lubricant tube 220 is configured between the gear housing 210 and a substantially cylindrical sleeve 280, which is fixedly mounted to the shaft journal 230 and arranged to surround the drive shaft 260. The outer dimension of the cylinder portion of the sleeve 280 allows it to be positioned so as to surround the drive shaft 260. upper part has a clear radial distance to the surrounding shaft journal 230. The axial extent of the sleeve 280 may extend from the axial outer portion of the shaft journal 230 and to the transition between the shaft journal 230 and the gear housing 210. Advantageously, the sleeve extends axially towards the gear housing 210 only to a position sufficiently large space is provided in the radial direction between the shaft journal 230 and the drive shaft 260 so that the lubricant tube 220 can have a sufficient dimension to be able to direct the desired lubricant flow to the sleeve 280. The sleeve 280 may be formed of metallic material or plastic and have lugs (not shown) arranged on the outer surface of the sleeve and which support the sleeve 280 r alternatively the inner surface of the surrounding shaft journal 230.
    The sleeve 280 is fixedly mounted on an element 255 located in the area at the outer end of the sleeve facing the planetary gear. The element 255 is advantageously designed as an annular end wall, which extends radially from the sleeve 280. The element 255 can be fastened by press-fitting to a shoulder formed on the end of the shaft pin 230 facing the planetary gear. Alternatively, the element 255 can be designed substantially as a crescent moon, the largest width of which is located in the vertical direction above the drive shaft 260. The attachment of the element 255 to the shaft pin can of course just as easily take place with one or more separate fastening elements. Likewise, the element 255 can be made in one piece with the sleeve or as a separate annular unit, which is attached to the sleeve 280, for example by welding.
    The element 255 is advantageously arranged eccentrically at the sleeve 280 and mounted in the shaft pin so that an oil flow receiving space P2 (see Figures 3a and 3b) is formed in the vertically upper part between the sleeve 280 and the inner wall of the shaft pin 230 in radial direction. On the other hand, the eccentricity means that substantially no space is formed at the vertically lower part between the sleeve 280 and the radially inner wall of the shaft journal 230. Similarly, due to the dimensioning of the sleeve relative to the enclosed drive shaft, a space P3 is formed between the sleeve and the drive shaft 260. Due to the eccentric location of the sleeve 280, the space has a greater distance between the sleeve 280 and the drive shaft 260 in the lower vertical part than in the upper part. The sleeve 280 thus advantageously forms at least two spaces P2 and P3 relative to the shaft journal 230 and the drive shaft 260. The sleeve 280 can be fixedly attached to the shaft journal 230 in any manner. Likewise, one or more support members may be provided on the outside of the sleeve 280 to supportively support the sleeve relative to the inner surface of the shaft journal 230.
    In the area at the end of the sleeve 280 facing the central gear, an end element 281 is correspondingly arranged, which is advantageously formed as an annular end wall, which extends radially from the sleeve 280 towards the outer surface of the drive shaft 260. The end member 281 abuts closely against the outer surface of the drive shaft 260 rotating during vehicle operation without touching it. Similar to the element 255, the element 281 may be made with a substantially greater radial height in the lower part in the vertical direction than in the upper part. Due to the eccentric location of the sleeve, the greater height of the element 281 can cover a larger part of the entire radial distance between the sleeve 280 and the outer surface of the drive shaft 260. Said larger part can amount to substantially the entire said distance at the coarsest drive axle dimension for which the wheel axle is intended. 10 15 20 25 30 12 The end element 281 functions as a radial wall which prevents Lubricant from flowing out of the space P3 in the sleeve 280 in the "wrong direction". Instead, the end member 281 directs the lubricant so that the flow thereof is directed toward the housing 240. The member 281 may be integral with the sleeve 280 or as a separate annular unit attached to the sleeve 280, for example by welding.
    According to an embodiment shown in Figure 3a, the lubricant tube 220 is attached to the sleeve 280 and connects via an opening 385 to the sleeve 280 and to the space P3 between the sleeve 280 and the drive shaft 260 at the end of the sleeve facing the central gear 212. The lubricant is arranged to be guided in the lubricant tube 220 from the gear housing 210 to the space P3 by means of gravity, of course. This is made possible by the fact that a height level of the lubricant tube 220 where the lubricant thrown up by the crown wheel 215 is caught is higher is a height level where the lubricant flows out of the sleeve 280 to the housing 240. The space P3 is a passage for guiding the lubricant towards the housing 240. The lubricant tube 220 may be attached to the sleeve 280 or to the surrounding gear housing 210 or the shaft journal 230 arbitrarily so that its outlet connects to the opening 385 in the sleeve 280. According to one embodiment, sealing elements are provided at the opening 385 of the sleeve 280 to minimize the risk of leakage. lubricant.
    According to an alternative embodiment, shown with reference to Figure 3b, the end member 281 is provided with an opening 386 to which the lubricant tube 220 connects. The opening 386 in the element 281 is then arranged to function as an inlet for lubricant to the space P3 between the drive shaft 260 and the sleeve 280. Also in this embodiment the lubricant will have a net flow from the central gear 212 to the housing 240.
    When the vehicle 100 is driven, the cover 240 rotates, a part of the lubricant contained therein being pressed against the inside of the cover 240 and thereby forming a thickness due to the lubricant film. The amount of Lubricant added to the cover 240 from the lubricant bath 205 in 210. The more the lubricant bath 205, the thicker the lubricant film. The gear housing lubricant supplied to the housing 240 from a per se known scraper 270 is arranged in the housing 240 and is fixed in the shaft pin 230. The scraper 270 has a vane 271 which irradiates the lubricant from the inside of the rotating housing 240. The scraper 270 also comprises a passage 272 which is arranged to direct the stripped lubricant to the shaft journal 230 and the space P2. Through the space P2 on the outside of the sleeve 280, the lubricant supplied from the wiper 270 is led back to the lubricant bath 205 in the gear housing 210. When operating the vehicle, the lubricant film has a maximum thickness determined by the position of the wiper.
    According to one embodiment (see figure 3b), a helical element 290 is fixedly arranged around the drive shaft 260 to improve the flow of the lubricant in the space P3 between the sleeve 280 and the drive shaft 260. The spiral 290 is arranged around the drive shaft 260 in a space between the sleeve 280 and the drive shaft 260 The spiral 290 can be made of plastic material or metallic material. The backflow of lubricant in the device 299 from the housing 240 to the gear housing 210 is also effected, of course, by gravity. It should be noted that a height level of the wiper 270, where the lubricant is wiped, is higher than a height level where the lubricant is led back from the housing 240 to the gear housing 210, namely at the end 280 of the sleeve 280 towards the central gear 212 and at a lower part of the shaft pin 230. 2805 facing the planetary gear element 255 prevents "incorrect" flow of the lubricant to a lower part of the housing 240. The element 255 thus has a sealing function and helps to direct the flow of lubricant from the wiper 270 to the space P2 between the outside of the sleeve 280 and inside the shaft pin 230 and further from the space P2 back to the gear housing 210. Figure 3a schematically illustrates how Lubricant is distributed according to an embodiment of the invention. The lubricant tube 220 directs lubricant from the gear housing 210 to the space P3 between the sleeve 280 and the drive shaft 260 via the opening 385 in the sleeve 280. The end member 281 prevents flow of the lubricant back to the gear housing 210 and instead directs the lubricant to the space P1 in the housing 240 and the plane therein.
    During operation of the vehicle, the housing 240 rotates and the lubricant is pressed by the formed lubricant film is continuously wiped off by the scraper 270, which directs the rotational force towards the inner surface of the housing 240. The lubricant is then passed through the channel 272 in the wiper to the space P2 between the shaft journal 230 and the sleeve 280. The element 255 prevents the lubricant from the wiper 270 from being led from the space P2 into the space P1 in the housing 240 (see Figure 2). Instead, the lubricant flows from the space P2 back to the lubricant bath 205 (see the left-hand arrows in Figure 2) via the outside of the sleeve 280 and the inside of the shaft journal 230.
    Figure 3b schematically illustrates how lubricants are distributed according to an alternative embodiment of the invention. In this case, the lubricant tube 220 directs lubricant from the gear housing 210 to the space P3 between the sleeve 280 and the drive shaft 260 via an opening 386 in the end member 281. This is also shown in Figure 2. As with the solution of Figure 3a, the end member 281 prevents flow of the lubricant back to the gear housing. 210. Instead, the lubricant, possibly by means of the helical element 290 in its rotation together with the drive shaft 260, is fed from the space P3 to the space P1 in the housing 240 and the planetary gear contained therein. In the same manner as described in connection with Figure 3a, the lubricant is then led via the planetary gear in the housing 240, the inner wall of the housing 240, the wiper 270, the space P2 and finally via the outside of the sleeve back to the gear housing 210.
    The foregoing description of the preferred embodiments of the present invention has been provided for the purpose of illustrating and describing the invention. It is not intended to be exhaustive or to limit the invention to the variations described. Obviously, many modifications and variations will occur to those skilled in the art. For example, the space P2 can be arranged to lead lubricating oil to the space P1 in the housing, while in this case the space P3 is used to lead lubricating oil back to the gear housing.
