    Te la arrangement to be fitted to the bogie vehicle
    Background of the invention
    The invention relates to a bogie arrangement for a bogie of a vehicle driven in difficult road or off-road conditions, and in particular to the bogie-mounted bogie of a heavy-duty vehicle adapted for transport use while driving and to the bogie-mounted bogie from its storage location.
    When driving in difficult road conditions, such as on icy roads or off-road, the friction of the vehicle's driving tires relative to the road surface may be reduced to the extent that the vehicle cannot advance on the road, and 10 the vehicle's tires run flat, ie the vehicle body does not move much in relation to the road. the driving tires of the vehicle rotate. A typical example of this is a knob on a log truck, which has to be driven, for example, on a slippery icy forest road or in similar difficult road conditions.
    In such vehicles, it is common to use a bogie axle (bogie) on the rear axle, whereby changes in the shape of the road surface do not move the vehicle body as much as in a bogie-free single axle system. In addition, the use of a bogie reduces the load on the road by the tires because the weight of the vehicle is more evenly distributed on the bogie tires as the height of the road surface varies.
    In said bogie axles, the drive rings may be arranged by means of the transmission of the vehicle either on both axles of the bogie or only on one of the axles. In some cases, where only one of the bogie axles is Drive, the transmission from the drive axle to the tires mounted on the non-drive axle can be transmitted via known coupling friction rollers (so-called Robson Drive25 system, for example TelikarhuJ manufactured by Nurmi Hydro Oy).
    With the above-mentioned use of the coupling friction rollers, the number of driving tires of the vehicle can be increased momentarily, and thus the friction of the vehicle in relation to the roadway can be increased, whereby the vehicle can better advance on its roadway. Friction coupling rollers are connected between the bogie rings, usually by a pneumatic or 30 electrical mechanism. Once the difficult road conditions have been overcome, the coupling friction rollers can be detached between the bogie tires by means of said mechanism. Coupling friction rollers are not kept on during road driving under normal driving conditions, as the coupling rollers would quickly wear out the tire surfaces, and at the same time the noise level of the tires would increase significantly.
    20185234 prh 13 -03- 2018
    In some cases, the friction between the roadway and the driving tires is so small that even when all the bogie tires are towed, the friction is not enough to move the vehicle. In this case, according to a prior art, a roller can be mounted around the bogie rings, by means of which the surface area 5 of the surface attached to the carriageway can be increased, and thus the tires together with the roller form the driving element of the vehicle. The use of a roller also has the advantage that the surface pressure on the carriageway is reduced, so that the vehicle, especially when driving on a soft carriageway, does not sink as much into the carriageway, whereby the vehicle travels more easily.
    The outer surface of the roll is typically formed with elongate protrusions perpendicular to the longitudinal direction of the roll, which further increase the friction of the roll relative to the roadway, thus increasing the grip of the driving element of the vehicle. The roll is typically formed of an inextensible or nearly inextensible material, such as metal or rubber, and the roll is mounted around the rings by securing and tightening the ends of the truncated roll by means of fasteners fitted thereto. A chain-like roll made of short metal sections made of metal is commonly referred to as a roll chain, while a mat-like roll made of rubber is called a roll mat.
    Since the roll mounted on a bogie catches a relatively large portion of the outer circumference of the tires, the friction between the roll and the tire is generally sufficient without protrusions formed on the inner surface of the roll, in some cases friction-increasing elements may be formed on the inner surface of the roll, for example elongate projections or grooves perpendicular to the roll. Typically, the roll is held on top of the ring by either external guides formed on the sides of the roll, projecting from the inner surface of the roll and resting on the sidewalls of the ring as the rings rotate. If the bogie has twin wheels, said cantilevered guides may be located in the middle of the track, so that the guides are positioned between the twin wheels as the tires rotate, thus holding the roller in place on the bogie.
    The problem with the arrangement described above is that the bogie-mounted roller 30 is cumbersome to mount on and off the bogie, and in addition, the roller, which is typically quite large and heavy, must be stored somewhere in the vehicle during road travel under normal road conditions. Because said roll is heavy, the installation of the roll by an individual is very challenging or even impossible. Since the vehicle 35 for the above-mentioned use typically has only one person, the use of the prior art is challenging. In addition
    20185234 prh 13 -03- 2018 when driving on terrain, the roller may loosen around the bogie tires so that the rotational movement of the drive tires is not transmitted to the roller, and the vehicle will stop moving.
    Brief description of the invention
    The object of the invention is thus to develop an arrangement by means of which the above-mentioned problems can be solved or their effect can at least be mitigated. The object of the invention is achieved by an arrangement which is characterized by what is stated in the independent claims. Preferred embodiments of the invention are the subject of dependent claims.
    The invention is based on the fact that roll bearing tracks are arranged on the lower surface of the support structures 10 of the vehicle pallet above the tires, on which the cut and straightened roll can be stored when the roll is not needed to be used. The roll can be lowered from the roll carrier tracks to the bogie tires by means of a traction device, for example a winch. Once the truncated roll is mounted around the rings, the ends of the roll are fastened together with fasteners adapted for this purpose, after which the roll is tightened tightly against the tires using a coupling friction roller designed for this purpose. The removal and storage of the roll takes place in the reverse order of the above-mentioned method.
    The advantage of the arrangement according to the invention is that the installation of the rollers both from the vehicle roll storage location to the bogie and from the bogie to the vehicle roll storage location 20 is easily possible using a traction device, even by an individual.

    Detailed description of the invention
    Figure 1 shows a vehicle with a bogie. The bogie 101 attached to the frame 130 of the vehicle 100 comprises two parallel bogie shafts 102, 103 spaced apart in the longitudinal direction L of the vehicle 100. The bogie shafts 102, 103 extend in the transverse direction W of the vehicle 100. The opposite ends of the first bogie shaft 102 have drive rings 103, each preferably consisting of two , supported by rims, form a twin wheel. At opposite ends of the second bogie axle 104 are in turn non-traction rings 105, each of which preferably consists of two rings supported on each other via rims, i.e. forming a twin wheel. The bogie 101 further comprises a frame structure through which the bogie axles 102, 104 are connected to the vehicle body 130. The body structure of the bogie 101 reduces terrain unevenness in the body 130 of the vehicle 100. The frame structure of the bogie 101 allows the bogie axle 102, 104 to move relative to each other so that does not move in height. For the sake of simplification, the figure does not show the frame structure of the bogie of the vehicle 100, the transmission system or the load-bearing structures.
    A breakable roll 25 110 is arranged around the twin wheels 103, 105 of the bogie 101, the loose ends of which can be fastened together by means of a fastening mechanism adapted for this purpose.
    The installation of the roller 110 on the bogie twin wheels 103, 105 takes place in the prior art as follows:
    The cut roll 110 is first applied straight to the carriageway longitudinally of the vehicle 100 either to the front of the tires 103, 105 of the bogie 101 or to the rear of the rings 103, 105 of the bogie 101 with respect to the longitudinal direction L of the vehicle.
    The bogie-side end of the roll 110 is then attached to, for example, a traction rope or chain which is rotated about one or both rings 103, 105 of the bogie 101 from above so that the traction rope rises on the bogie 101 ring 103,105 closest to the bogie 101 of the roll 110.
    20185234 prh 13 -03- 2018
    Finally, the traction rope is placed between the ring 103, 105 and the carriageway on the opposite side of the roller 110 of the bogie 101, for example by slightly rotating the ring 103, 105 and at the same time wedging the traction rope between the ring 103, 105 and the carriageway.
    When the vehicle 100 is then moved away from the roller 110 in the longitudinal direction L of the vehicle, the traction of the roller 110, first pulled by a rope, first rises over the rings 103, 105 of the bogie 101. As the vehicle 100 is further moved in said direction, the roller 110 eventually ends up in a position where the roller 110 is otherwise around the rings 103, 105, but the ends of the roller 110 are loose relative to each other. In this step 10, the traction rope can be detached from the end of the roll 110 and the ends of the roll 110 are fastened to each other by a fastening mechanism which can also be used to tighten the roll 110 around the bogie rings 103,105.
    It is conventional that before the loose ends of the roll 110 are finally fastened together, the ends of the roll 110 are tied together by temporary fasteners, for example chains, so that the ends of the roll 110 remain loosely together so that the ends of the roll 110 are obtained by moving the bogie 101 between the rings 103, 105. above. In this case, a roll tensioning tool is attached to the ends of the roll 110, by means of which the ends of the roll 110 can be pulled together or at least so close to each other that the ends of the roll 110 can be fastened to each other with fasteners fitted thereto.
    The roll 110 is removed around the rings 103, 105 of the bogie 101 by opening the fastening mechanism, after which the vehicle 100 is moved in either direction until the vehicle 100 is completely off the roll 110, whereby the ground roll 110 can be rolled up and stored in the vehicle 100. for example, to the loader.
    Figure 2 shows a roll arrangement 200 according to the invention.
    The roll arrangement 200 comprises a roll carrier track 201 mounted on the frame of the vehicle 100, a traction device 205 attached to the vehicle with a traction rope 206, a support 250 and a coupling friction roller 500 mounted on the frame 100 of the vehicle 100.
    The roll 110 is pullable from its end 112, 113 to and from the roll carrier track 201. The roller 110 slides on the roller support track 201. The roll carrier track 201 both supports the roll 110 and guides the roll 110 as the roll 110 is pulled into and out of the roll support track 201. The roll carrier track 201 may be formed of spaced L-shaped rails 212, with the horizontal branches of the L-shaped rails 212 forming support surfaces for the roll support track 201 and the vertical branches forming lateral guide surfaces for the roll support track.
    20185234 prh 13 -03- 2018
    201. The L-shaped rails 212 thus extend in the longitudinal direction L of the vehicle. The track support track 201 is slightly wider in width than the roller 110, whereby the track support track 201 guides the roller 110 sliding on the track support track 201 parallel to the track support track 201. The width delimited by the surfaces of the roll support track 201 in the lateral direction of the roll 110 may preferably be 0.5-2 cm wider than the roll 110.
    The track support track 201 is located in the space between the rings 103, 105 of the bogie 101 and the load of the vehicle, preferably below the frame supporting the load space. The roll carrier track 201 is adapted to slidably receive a roll 110 which is movable, cut and straightened on the roll carrier track 201. Preferably, the roll 110 can be pulled onto the roll carrier track 201 from 201 from the rear part 210 directly to the tires 103,105 of the bogie 101.
    The track carrier track 201 extends longitudinally longitudinally L of the body 130 of the vehicle 100 from the bogie 101 rear ring 105 toward the front of the vehicle 100, preferably extending at least vertically to the axle centerline of the bogie 101 front ring 103, but preferably ending before the cab 120. with respect to the longitudinal direction (L) of the body 130. The track carrier track 201 is arranged in the vehicle 100 laterally on the bogie rings 103, 105 of the vehicle 100 so that the lateral center portion of the vehicle 110 on the track 110 tracked on the track carrier track 201 is vertically aligned with the lateral center portion of the bogie 101 rings 103, 105 on the vehicle 100. The roll carrier track 201 may be located laterally in the vehicle 100 above the rings 103, 105 of the bogie 101 so that the longitudinal centerline of the roll 110 placed on the roll carrier track 201 and the longitudinal centerline of the rings 103,105 of the bogie 101 are in the same vertical plane.
    The track carrier track 201 is one or more guides 100 on both sides of the driving guide 100. At the rear of the track support track 201 there is a first section 210 in which the track support track 201 curves downwards from the longitudinal direction of the body 130 of the vehicle 100. The curvature of the first portion 210 of the roll carrier track 201 is preferably 25-90 ° with respect to the longitudinal direction L of the body 130 of the vehicle 100. The curvature of the first portion 210 of the roll carrier track 201 may consist of a continuous circular arc or individual straight pieces joined together at an angle to each other they make up
    20185234 prh 13 -03- 2018 angular arc. The curvature of the rear 210 of the roll carrier track 201 facilitates pulling the roll 110 onto the roll carrier track 201 and removing the roll 110 from the roll carrier track 201.
    Preferably, the rolled end 112, 113 of the roll 110, which is in the space between the portion of the roll 110 below the rings 103, 105 of the bogie 101 and the inlet end of the roll carrier track 201, is preferably drawn on the roll carrier track 201, the roll 110 being provided on the roll carrier track 201 at a gentler angle. 201. The take-up end of the roll carrier track 201 means the open end of the roll carrier track 201 from which the roll 110 is to be provided to the roll carrier track 201. This take-up head may be located in the direction of travel of the vehicle 100 behind the bogie 101 or according to an embodiment of the invention in front of the bogie 101.
    According to an embodiment of the invention, the roll carrier track 201 15 may curve about its longitudinal axis of the body 130 of the vehicle 100, preferably 45-90 degrees. In this embodiment, the sides of the roll 110 extend toward the roll 110 arranged on both sides of the roll support track 201, supported by the inner surfaces of the open rails.
    A roll 110 placed on the roll carrier track 201 may replace a mudguard mounted on the rollers 103, 105 of the bogie 101. The rear end 112 of the roll 110 placed on the track carrier track 201 may then remain suspended from the track support track 201 so that the rear end 112 of the roller 110 extends from the rear end of the track support track 201 to a distance from the road surface. The distance from the rear end 112 of the roll 110 to the road surface may preferably be 5-25 cm. The rear end 112 of the roll 110 is lower than the lower surface of the yarn support track 201, but it does not touch the roadway. The carriageway is longitudinal L of the body 130.
    According to an embodiment of the invention, a second portion 220 may be formed on the roll carrier track 201, along the length of which the roll 110 placed on the roll carrier track 201 can be lowered below the roll carrier track 30 201 in front of the roll. The portion of the roll 110 lowered in the forward direction of the bogie 101 from the vehicle 100 may act as a front fender for the bogie 101. After the second portion 220, the roll carrier track 201 may extend parallel to the body 130 L1 toward the front of the vehicle 100. At the ends of the roll carrier track 201 delimited by the second portion 220, the roll carrier track 201 curves downward from the longitudinal direction of the body 130 to make the roll 110 35 slide more easily on the roll carrier track 201. The second section 220 in the middle of the roll
    20185234 prh 13 -03- 2018 the support track 201 may lack the horizontal surfaces of the support rails 212 supporting the roll 110, preferably 20-50 cm in length.
    The track support track 201 may be divided into several different parts, which can be separately fastened to the frame 130 of the vehicle 100, for example at the bogie axles of the vehicle 100. The track carrier track 201 may have one or more portions where the mounting height of the track carrier track 201 relative to the frame 130 of the vehicle 100 changes. The roll support track 201 may be open at the bottom in the middle, so that the roll support track 201 supports the roll 110 only from below the side portions of the roll 110. The openness of the lower portion of the roll carrier track 201 reduces the weight of the roll support track 10 201, while leaving free space for the guides 260 of the center portion of the inner surface of the roll 110.
    A traction device 205, for example a winch, may be fitted to the front of the vehicle 100, which may be located immediately behind the person 100 of the vehicle 100. The traction device 205 is preferably located between the person (cab) 120 of the vehicle 100 and the support track 201 of the roller 15 at approximately the height of the track support track 201. The traction device 205 may be attached to the body 130 of the vehicle 100. The traction device 205 may produce a preset constant torque regardless of the traction speed of the traction device 205, for example the rotational speed of the winch. The traction device 205 may be hydraulically or electrically operated and may be controlled immediately by the mechanical or electrical controls 20 in the traction device 205 and / or by an electrical remote control. The torque (traction) produced by the traction device 205 may be adjustable, and the traction device 205 may be able to both pull and release the traction rope 206, preferably at different speeds. The traction device 205 includes a traction rope 206 for pulling the roll 110, which traction rope 206 may be, for example, a rope, a chain or a wire. A bracket, such as a hook or the like, may be provided at the end of the traction rope 25 206 to facilitate attachment of the traction rope to the roll 110.
    According to one embodiment of the invention, the traction device 205 comprising the traction rope 206 may be located at the front of the vehicle 100, approximately behind the steering space, laterally in the middle of the vehicle 100, with one traction device 205 30 being able to pull, for example using the swivel wheels (not shown) attached to the bogies 101. 100 of both-side rollers 110 of the vehicle either simultaneously or alternately.
    According to an embodiment of the invention, in the direction of travel of the vehicle 100, the front or rear side of the bogie 101 has one or more axes, and the tin web 201 of the roll carrier 35 may extend to said axle or said axles. The roll arrangement 200 may be arranged so that the roll 110 can be mounted on a roll carrier 9
    20185234 prh 13 -03- 2018 in addition to the tires 103, 105 of the bogie 101 directly from the tin track 201 around the tires of one or more additional axles on the front or rear of the bogie 101 of the vehicle 100. There may be two traction devices 205, 206 in the vehicle, one on each side of the vehicle 100 for mounting the rollers 110 on the tires 103,105 of the bogies 101 on both sides of the vehicle 100.
    Figure 3 shows a roll arrangement 200 according to the invention, in which the roll 110 is mounted on the rings 103,105 of the bogie 101.
    According to an embodiment of the invention, the roll 110 is tightened around the rings 103, 105 of the bogie 101 by means of a coupling friction roller 500. The coupling 10 friction roller 500 is pressed against the roll 110 by the tightening mechanism 510 of the coupling friction roller 500. The tightening mechanism 510 can be operated by the traction produced by the traction device 205 attached to the vehicle 100. The operation of the tightening mechanism 510 is explained in more detail in connection with the description of Fig. 5.
    Figure 4 shows a fastening mechanism 400 for a roll 110 according to an embodiment of the invention.
    The fastening mechanism 400 comprises fastening loop sections 405 fixedly fixed at both ends 112, 113 of the roll 110, comprising one or more fastening loops 401. The fastening loops 401 are arranged so that the ends 112,113 of the roll 110 are opposed to each other by interlocking the fastening loops 40 are aligned in the width direction of the roll 110. The mounting pins 402 can be inserted into the holes of the interleaved mounting loops 401, locking the roll ends 112, 113 together. The ends of the mounting pins 402 may have transverse holes for the shock 403. The mounting pins 402 have a longitudinal hole extending in the center of the length of the mounting pin so that the wire 404 can be threaded through the holes. The wire 404 is threaded through all the mounting pins 402. The wire 404 threaded through the mounting pins 402 engages the pin 403 at the side edges of the roll 110. The mounting mechanism 400 comprises a plurality of separate mounting loop sections 405 at each end 112, 113 so that the roller does not damage the mounting 30 3.
    According to one embodiment of the invention, the holes in the fastening loops 401 may be in the shape of a pear cross-section, with the hole narrowing away from the end of the roll in the longitudinal direction of the roll, thereby facilitating the insertion of the fastening pins 402 into the holes. The ends of the fastening pins 402 may then have a flange slightly smaller than the larger end of the holes of the fastening loops 401, which, however, is
    20185234 prh 13 -03- 2018 larger than the smaller end of the hole of the fastening loop 401, whereby the pins cannot move in the lateral direction of the roll 110 when the roll 110 is taut. Said embodiment requires the use of a tightening mechanism of the outer roll 110, for example a coupling friction roller 500.
    Figure 5 shows the structure of the tightening mechanism 510 used to tighten the roll 110 according to an embodiment of the invention.
    The tensioning mechanism 510 comprises a fixed portion 515 fixedly attached to the frame 130 or the track carrier track 201 of the vehicle 100, a movable portion 520 supported parallel to the frame, an articulated support arrangement 530, and a coupling friction roller 500.
    The coupling friction roller 500 engages the clamping mechanism 510 between the fixed portion 515 and the movable portion 520 via an articulated support arrangement 530. The coupling friction roller 500 is rotatably supported at its ends on the roll support track 201 by means of a roll clamping mechanism 510. The roll tensioning mechanism 510 comprises a first support arm 516 at each end of the clutch 15 friction roller 500, which connects the clutch friction roller 500 to the first support member 515 fixedly attached to the vehicle 100 frame or track support track 201. The roller clamp to the movable support member 520. An angle α is formed between the first support arm 516 and the second support arm 517. The attachment points of both ends of the first support arm 516 and the second support arm 517 are formed by articulation points. When the movable part 520 is moved longitudinally to the left in the longitudinal direction of the roll support track 201, the nip support point fixed to the movable part 520 of the second support arm 517 moves with the movable part 520 to the left in the figure. The second support arm 517 thus moves closer to the first support arm 516, whereby the support arms 516, 517 press down on the coupling friction roller 500 in the figure. When the moving part 520 is moved to the right in the figure, the support arms 516, 517 raise the coupling friction roller 500 in the figure upwards. Thus, by means of the support arms 516, 517, the coupling friction roller 30 500 can be moved against the roller 110 or away from the roller 110.
    The coupling friction roller 500 is shaped so that the coupling friction roller 500 tapers at the center of the roll 110 as it moves toward both side edges of the roll 110. This bombarded design allows the roll 110 to rotate longitudinally as the bogie 101 moves without adding too much pressure to the side edges 35 of the roll 110. The coupling friction roller 500 may have a portion of the shape of a flat cylinder in the central part, from which, when going towards the side edges of the roll 110, a bombardment, i.e. a diameter
    20185234 prh 13 -03- 2018 continuous decrease, i.e. taper begins. The coupling friction roller 500 may be in two parts, the coupling friction roller 500 comprising two separate rollers, a first roller 501 and a second roller 502, leaving free space between the first 501 and second roll 502 of the coupling friction roller 500 for the roller 110 center guide 560 when the roller 110 is in storage on the roll carrier 201.
    According to one embodiment of the invention, the unitary coupling friction roller 500 has a groove in the center for the guide 260 of the center portion of the roll 110. This feature is advantageous when the roll 110 is in its storage position on the roll support track 201 and the coupling friction roller 500 is raised to the up position.
    The movable part 520 of the tensioning mechanism is slidably supported by supports 512 fitted to the lower part of the track carrier track 201, the movable part 520 of the clamping mechanism 510 is thus able to slide over the upper surfaces of the supports 512 longitudinally The supports 512 guide the movable portion 520 of the tensioning mechanism 510 in the lateral direction of the roll carrier track 201.
    The movable portion 520 of the tensioning mechanism 510 has attachment points 525, 526 at both ends longitudinally at the body 130 of the vehicle 100 for attaching the traction rope 206. The transverse supports 527 of the lower ends of the movable part 520 mo20 of the tightening mechanism 510 have a notched support in the middle for the guide 260 of the central part of the roll 110. When the movable portion 520 of the tensioning mechanism 510 is pulled by the traction device 205 toward the front of the vehicle 100, the tensioning mechanism 510 tightens the clutch friction roller 500 against the roller 110, and thus tightens the roller 110 around the rings 101, 105 of the roller 110 to a tension proportional to the tensioning member Tensioning of the roller 110 can be performed by engaging the traction rope 206 of the traction device 205 directly in the direction of travel of the movable portion 520 of the tensioning mechanism 510 to the front engagement point 525, and directing the traction device 205 to pull the traction rope 206 with a preset controlled traction force. When the roller 110 is sufficiently tight, it cannot fall off the bogie 101, and at the same time the rotational movement of the traction rings 103, 105 is transmitted to the roller 110 by friction.
    Loosening of the roll may otherwise be performed in a similar manner, but the traction rope 206 must be rotated through a support roller 250 at the rear of the roll carrier track 201 to change the traction direction of the rope 206 to the rearward direction of the vehicle, and the coupling of the traction rope 206
    20185234 prh 13 -03- 2018 is fastened to the attachment point 526 of the rear of the tensioning mechanism 510. As the movable portion 520 of the tensioning mechanism is pulled toward the rear of the vehicle, the clutch friction 500 rises from the roller 110 through the articulated support arrangement 530.
    According to an embodiment of the invention, the roller 110 placed around the bogie can be tightened by means of a uniform coupling friction roller 500. The shape of the clutch friction roller 500 made for this purpose differs from the typical clutch friction roller used to form the transmission in that the length of the clutch friction roller 500 of the invention almost corresponds to the width of the bogie twin wheels. The coupling friction roller 500 is further shaped to be at its thickest in the longitudinal direction of the vehicle at the bogie centerline of the bogie 110, thinning from the bogie centerline to the transverse direction of the vehicle, allowing the bogie 110 to move more freely as the bogie 101 moves off-road. When the coupling friction roller 500 is cylindrical, an excessive force of 15 could be applied to the edges of the roller 110 as the bogie 101 follows the terrain due to rotational movement with respect to the longitudinal axis of the roller 110.
    According to an embodiment of the invention, the tightening of the coupling friction roller 500 may be effected by a separate hydraulically, pneumatically or electrically operated mechanical force generating device, and the coupling of said force 20 by a mechanism applying the friction roller 500 to the roll 110.
    Figure 6 shows the structure of a support roller 250 attached to a roll carrier track 201 according to an embodiment of the invention. The support roller 250 may comprise two separate rollers, a first roller 252 and a second roller 253, which are supported at both ends on the shaft 251 of the support roller 250 by means of bearings 255. The shaft 251 has a groove 254 arranged between the rollers 252, 253, on the outer circumference of which a groove is formed for the traction rope 206. The rollers 252, 253 the roller 254-side ends are tapered in the middle of the inside of the roll 110 of guides 260 for. At both ends of the shaft 251 are mounting bolts 256 for securing the support roller 250 to the body 130 or the track support track 201 of the vehicle 100. The diameter of the pulley 254 30 is smaller than the diameter of the rollers 252, 253.
    According to an embodiment of the invention, the unitary support roller 250 used as a swivel wheel has a central groove for the traction rope 206, the traction rope 206 preferably remaining in the longitudinal direction of the roll carrier track 201 in the center, which facilitates retraction of the roll 110 to the roll support track 201. .
