    VEHICLE ROLLER HEAD CONNECTION ARRANGEMENT
    TECHNICAL FIELD The invention relates to a joint arrangement for the ends of a vehicle roll.
    BACKGROUND OF THE INVENTION In difficult road conditions, when the friction between the tires and the roadway is low, the traction tires of the vehicle may lose their grip on the road surface. The vehicle does not advance even if the vehicle's driving tires are rotating. For example, a log truck often has to drive on slippery icy forest roads or in similar difficult road conditions, which means that the friction between the driving wheels and the roadway is low.
    In heavy vehicles, a bogie axle structure is usually used on the rear axle. The bogie reduces the movement in the vehicle body caused by changes in the shape of the road surface compared to a bogie-free separate axle system. The bogie also distributes the weight of the vehicle more evenly to the bogie tires as the height of the road surface varies, thereby reducing the load exerted by the tires on the roadway.
    The transmission of the vehicle may be connected only to one axle of the bogie or to both axles of the bogie. In a vehicle where only one of the bogie axles is Driven, the force can be transferred from the driving axle to the non-drawn axle via the coupling friction rollers. The ability of the vehicle to travel is improved when the number of traction tires is increased by means of clutch friction rollers. The coupling friction rollers can be connected between the bogie rings and removed therefrom by means of a pneumatic or electric mechanism. Coupling friction rollers wear the tires> and increase the noise level, so they are only used momentarily when needed. D 25 The friction encountered by the towing tires can sometimes be so small that even 5 bogie traction tires are not sufficient to move the vehicle. In this case, a roller can be mounted around the bogie rings, by means of which the area of the driving surface acting on the carriageway can be increased. The vehicle tires E then together with the roller form the driving element of the vehicle. Act 30aa also reduces the surface pressure on the carriageway, so that the vehicle does not sink so much into the soft carriageway. 2 Elongate projections substantially perpendicular to the longitudinal direction N of the roll can be formed on the outer surface of the roll, which further increase the friction of the roll relative to the carriageway. The roll is typically
    ti of non-stretchable or nearly non-stretchable material such as metal or rubber. The roll is mounted around the tires by fastening and tightening the ends of the cut roll together with fasteners fitted to them. A chain-like roll formed of short metal sections, i.e., track shoes, is commonly referred to as a track chain, while a mat-like roller made of rubber is called a track mat.
    The contact surface between the roll and the outer circumference of the traction rings is generally relatively large, whereby the friction between the roll and the tire generally prevents the roll from sliding on the tire. The inner surface of the roll may, if necessary, comprise friction-increasing elements to prevent the roll from slipping on the tire. The sides of the roll generally have cantilevered guides which protrude from the inner surface of the roll and rest on the sidewalls of the tire as the tires rotate. In bogies with twin wheels, said protruding guides may be located in the middle of the track. The guides are then positioned between the twin wheels, preventing the roller from slipping on the tires.
    At each end of the roll there are usually connecting means by means of which the opposite ends of the roll can be connected to each other. The connecting means of the first end of the roll form a connection with the connecting means of the second end of the roll. At each end of the roll there may be connecting loop parts comprising at least one connecting loop. The connecting loops can interleave with respect to each other when the ends of the roll are placed opposite each other, whereby the connecting pins can be pushed through the holes in the line of the connecting loops. The connecting pins thus connect the ends of the roll together. The connecting pins can be locked in place by pushing the pin through the transverse pin holes on the outside of the connecting pins.
    > 25 SUMMARY> It is an object of the invention to provide a new type of arrangement for connecting the ends of a vehicle roll Ö.
    The arrangement for connecting the ends of the vehicle roll according to the invention is = defined in claim 1.
    E: The roll end connection arrangement according to the invention enables easy and reliable connection of the roll ends to each other.
    The connection of the LO roller ends can be done manually or with 5 connection tools designed for this purpose. Joining the N ends of the roll with a joining tool is quick and reliable.

    DESCRIPTION OF THE PREFERRED EMBODIMENTS Figure 1 shows a vehicle with a bogie. The figure shows the frame structure 110 and the cab 115 of the vehicle 100 as well as the wheels. Attached to the frame structure 110 of the vehicle 100 is a bogie 120 comprising two parallel bogie shafts 121, 122 spaced apart in the longitudinal direction L of the vehicle 100. The bogie shafts 121, 122 O extend in the transverse direction W of the vehicle 100. At opposite ends of the first bogie shaft 121 is traction rings 123, which may be formed by twin wheels supported by rims. The opposite ends of the second bogie axle 122, in turn, have non-traction rings 124, which can also 2 consist of twin wheels supporting each other via rims. The bogie 120 also provides a frame structure through which the bogie axles 121, 122 are connected to the vehicle frame structure 110. The frame structure of the bogie 120 reduces movement due to terrain unevenness in the body structure of the vehicle 100.
    110. The frame structure of the bogie 120 allows a certain amount of mutual height movement of the bogie axles 121, 122 so that the frame structure 110 of the vehicle 100 does not move in the height direction. For simplicity, the figure does not show the frame structure of the bogie 120 of the vehicle 100, the transmission system or the load compartment support structures.
    A breakable roll 200 is arranged around the twin wheels 123, 124 of the bogie 120, the loose ends of which can be fastened together by means of a fastening mechanism adapted for this purpose.
    Roller 200 can be mounted on bogie twin wheels 123, 124 as follows.
    First, the truncated roll 200 is applied straight to the carriageway in the longitudinal direction L of the vehicle 100, either in front of the tires 123, 124 of the bogie 120 or behind the rings 123, 124 of the bogie 120 with respect to the longitudinal direction L of the vehicle.
    Next, the bogie-side end of the roll 200 is attached to, for example, a traction rope or chain that is rotated about one or both rings 123, 124 of the bogie 120 from above so that the tow rope rises over the ring 123, 124 of the bogie 120 closest to the bogie 120 of the roll 200.
    Finally, a traction rope is placed between the ring 123, 124 and the carriageway on the opposite side of the bogie 120 of the bogie 120, for example by slightly rotating the ring 123, 124 while wedging the traction rope between the ring 123, 124 and the carriageway.
    When the vehicle 100 is then moved from the roll 200 longitudinally of the vehicle away, the roll 200 rises first on the rings 123, 124 of the bogie 120 when pulled by a traction rope. As the vehicle 100 is further moved in said direction, the roll 200 eventually ends up in a position where the roll 200 is otherwise around the rings 123, 124, but the ends of the roll 200 are loose relative to each other. At this point, your zipper can be removed from the ends of the roll 200 and the ends of the roll 200 are secured together by a fastening mechanism. The fastening mechanism can also be used to tighten the roll 200 around the rings <123, 124 of the bogie 120. > 30 The ends of the roll 200 can be tied together with temporary fasteners, e.g. E chains, before the loose ends of the roll 200 are finally fastened together. 2 The ends of the roll 200 thus remain loosely together, whereby the ends of the roll 200 are obtained by moving the vehicle 100 between the rings 123, 124 of the bogie 120 above the bogie 120. A roll tensioning tool can then be attached to the ends of the roll 200 to pull the ends of the roll 200 together or at least so close to each other that the ends of the roll 200 can be attached to each other by means of fasteners fitted thereto.
    The removal of the roll 200 around the rings 123, 124 of the bogie 120 takes place by first opening the fastening mechanism and then moving the vehicle 100 in either direction until the vehicle 100 has completely moved off the roll 200. The ground roll 200 can then be rolled up and stored in its intended place in the vehicle.
    100.
    Figure 2 shows a vehicle with a roll arrangement, in which the roll is in the storage position on the roll support track.
    The roll arrangement comprises a roll support track 300 located above the rings 123, 124 of the bogie 120 of the vehicle 100, a traction device 400 with a traction rope 410, a support roller 440, and a coupling friction roller 450. The roll support track 300 and the traction device 400 may be attached to the vehicle 100 frame structures.
    The roll 200 is pullable at its end 210, 220 into and out of the roll support track 300. The roll 200 slides on the roll support track 300. The roll support path 300 both supports the roll 200 and guides the roll 200 as the roll 200 is pulled into and out of the roll support path 300.
    The roll support track 300 may be formed by spaced apart vertical side support elements and horizontal bottom support elements. The bottom support elements form the support surface of the roll support track 300 and the side support elements form the lateral guide surfaces of the roll support track 300. The width of the roll support track 300 may be 0.5-2 cm wider than the roll 200.
    The roller support track 300 may be located in the space between the tires 123, 124 of the bogie 120 and the load compartment of the vehicle 100. The cut and straightened roll 200> can be slidably pulled at one end 210, 220 onto the roll support track 300 O. The roll 200 can be pulled onto the roll carrier 300 in the direction of travel of the vehicle 100 from the rear 320 of the roll carrier 300 directly from the bogie 120, 124. The roll 200 can be pulled from the roll carrier 300 E from the rear 320 of the roll carrier 300 directly from the rear of the roll 300 for tires 123, 124.
    LO The roller support track 300 may extend longitudinally L longitudinally L of the vehicle structure 110 at least at the rear ring 124 of the bogie 120 over the front ring 123 of the bogie 120 toward the cab 115 of the vehicle 100. In any case, the roller support track 300 terminates
    at a distance from the cab 120 of the vehicle 100. The longitudinal direction of the roller support track 300 may be parallel to the longitudinal direction L of the frame structure 110 of the vehicle 100. The roll support track 300 may be laterally centered on the rings 123, 124 of the bogie 120.
    The vehicle 100 may have two roll support tracks 300, i.e. one on each side of the vehicle 100. The roll support track 300 may be formed of straight and / or curved portions. The rear portion 320 of the roll support track 300 may be formed of a downwardly curved portion. The curvature of the rear portion 320 of the roll support track 300 facilitates pulling the roll 200 onto the roll support track 300 and removing the roll 200 from the roll support track 300.
    The roll 200 placed on the roll support track 300 can replace the fender mounted on the rings 123, 124 of the roll 120. The rear end 220 of the roll 200 placed on the roll support track 300 may then remain suspended from the roll support track 300 so that the rear end 220 of the roll 200 extends from the rear end 320 of the roll support track 300 to a distance from the road surface. The distance from the rear end of the roller 200 to the road surface 220 may be 5-25 cm.
    The roll support track 300 may comprise a central portion 310 located in front of the bogie 120. The central portion 310 of the roll support track 300 may include an opening from which the roll 200 may be lowered below the roll support track 300.
    The roll 200 can then act as a front fender for the bogie 120. After the central portion 310, the roll support track 300 may continue parallel to the frame structure 110 toward the front of the vehicle 100. At both ends of the central portion 310, the roll support path 300 may curve downward from the longitudinal direction L of the body 110 to make the roll 200 slide more easily on the roll support path 300. The roll support track 300 may be divided into a plurality of different portions that are separately attachable to the frame structures 110 of the vehicle 100. The roll> support track 300 may have one or more portions where the mounting height of the roll support track 300 relative to the vehicle frame structures 110+ changes. > 30 A traction device 400 may be fitted to the front of the vehicle 100, for example a winch attached to the frame structures 110 of the vehicle 100. The traction device 2 400 may be hydraulically or electrically operated. The traction device 400 may be adapted to both pull and release the traction rope 410 at different speeds. Traction> 400 can be located at the front of the vehicle 100, in the middle of the vehicle. With one traction device 400 and swivel wheels arranged on the sides of the vehicle 100,
    the rollers 200 on both sides of the vehicle 100 can then be pulled either simultaneously or alternately.
    The front or rear of the bogie 120 may have one or more additional axles.
    The support path 300 of the roll can then continue up to said additional axis.
    The roll 200 may be mounted from the roll support track 300 directly around the rings 123, 124 of the bogie 120 around the rings of one or more additional axles on the front or rear of the bogie 120 of the vehicle 100.
    Figure 3 shows a vehicle with a roller arrangement in which the roller is in the operating position on the bogie rings.
    The roll 200 can be tightened around the rings 123, 124 of the bogie 120 by means of a coupling friction roller 450.
    The coupling friction roller 450 can be pressed against the roll 200 by the tightening mechanism of the coupling friction roller 450.
    The tightening mechanism can be operated by the traction produced by the traction device 400 attached to the vehicle 100.
    Figure 4 shows the ends of the roll and the connecting means therein.
    Only the opposite ends 210, 220 of the roll 200 are shown. The first end 210 of the roll 200 comprises connecting means 500 and the second end 220 of the roll comprises counter-connecting means 600. The first end 210 of the roll 200 is inverted in the figure, i.e. the inner surface 201 of the roll is up.
    This representation is - chosen so that the structure of the connecting means 500 at the first end of the roll 200 becomes clearer.
    The connecting means 500 and the mating means 600 at opposite ends 210, 220 of the roll 200 form a connection between the roll 200.
    The first end 210 of the roll 200 has three connecting means 510, 520 and the second end of the roll 200 also has three mating means 610, 620. The connecting means 510 at the longitudinal outer edges of the first end 210 of the roll 200 are identical and the connecting means 520 in the middle of the roll 200 is O slightly smaller in physical size.
    The connecting means 610 at the longitudinal outer edges 220 of the second end 220 of the roll 200 are identical and the connecting means 620 in the center of the roll 200 is slightly smaller in physical size.
    E At the first end 210 of the roll 200, between the connecting means 510 at the longitudinal outer edges 2 and the connecting means 520 on the longitudinal invention line of the roll 200, there are first perforating means 550 for the joining tool.
    At the other end 220 of the roll 200, the longitudinal outer edge mating means 610 and the longitudinal biscuit line of the roll 200
    Between the mating means 620 there is a second hole means 650 for the joining tool. The first hole means 550 and the second hole means 650 may be identical.
    The connecting means 500, the mating means 600 and the perforating means 550, 650 may be made of metal pieces fastened by fastening means, e.g. bolts, to the track 200. The perforating means 550, 650 may consist of a body resting on the inner surface of the roll 200 and a body resting on the outer surface of the roll 200. Through these pieces as well as the roll 200 extends a hole.
    The outer surface 202 of the roll 200, which is thus visible at the other end 220 of the roll 200, has transverse projections 700. The purpose of these projections 700 is to increase the friction of the outer surface 202 of the roll 200 in the roadway.
    By the inner surface 201 of the roll 200 is meant the surface of the roll 200 which abuts the tires of the vehicle when the roll 200 is mounted on the tires of the vehicle and the ends 210, 220 of the roll 200 are attached to each other. The outer surface 202 of the roll 200, in turn, refers to the surface of the roll 200 that extends away from the tires of the vehicle when the roll 200 is mounted on the tires of the vehicle and the ends 210, 220 of the roll 200 are secured together.
    Figure 5 shows a magnification of one pair of connecting means.
    The connecting means 510 located at the first end 210 of the roll 200 is thus further shown inverted, i.e. the inner surface of the connecting means 510 is shown at the top. This representation has been chosen in order to better understand the structure of the connecting means 510.
    The connecting means 510 comprises a body 510A attached to the first end 210 of the roll 200. The body 510A comprises an opening 514 extending elongately in the transverse direction W of the roll 200, which opens into a housing 515 inside the body 510A. The body 510A further comprises a roll 200 in the longitudinal direction O L extending into a slot 516 which cuts the body 510A and the housing 515 therein and the opening 514 into two parts.
    The body 510A of the connecting means 510 may be substantially in the shape of a lying U-E letter, with the first end 210 of the roll 200 being spaced between the prongs of the letter U-2 at a distance from the bottom of the letter U.
    The body 510A of the connecting means 510 may consist of a first side body portion 511 abutting the inner surface of the roll 200, a second side body portion 512 abutting the outer surface of the roll 200, and a curved base body portion 513 connecting the side body portions 511, 512.
    the body portion 513 may be spaced from the first end 210 of the roll 200. The body opening 514 of the connecting means 510 is located in the first side body portion 511. The opening 514 opens to the first end of the base body portion 513, the side body portions 511, 512, and the roll 200. 210 to define a housing 515. A slot 516 in the body 510A of the connecting means 510 extends in the longitudinal direction of the roll | in the base body portion 513 and in the side body portions 511,
    512. The slot 516 cuts the body 510A and the housing 515 and the opening 514 into two parts. The slot 516 extends longitudinally L through the base body portion 513 of the track 200. Slit 516 is located in the center of the base body portion 513. The connecting means 510 thus consists of a U-shaped body. The first branch of the letter U forms a first side frame portion 511 and the second branch of the letter U forms a second side frame portion 512. The curved bottom portion of the letter U forms a curved bottom body portion 513. The base body portion 513 is thus outwardly curved. The first side frame portion 511 and the second side frame portion 512 of the connecting means 510 may be formed of substantially planar pieces. The base body portion 513 may be formed of a planar body bent to an arc. The connecting means 510 is attached to the track 200 so that the track is positioned between the side frame portions 511, 512. The connecting means 510 is then fixed to the track 200, the track 200 and the connecting means 510 by bolts and nuts 800 extending through the side frame portions 511, 512. The first end 210 of the track 200 is spaced from the base body portion 513, whereby the first end 210 of the track 200 513, and a space O 515 of the connecting means 510 is formed in the space between the side frame portions 511, 512. This housing 515 may form a channel 515 in the transverse direction W + through the track 200. The first side frame portion 511 of the connecting means 510 is located on the roll. 200 and the second side frame portion 512 of the connecting means 510 are located on the outer circuit of the closed loop LO formed by the roll 200. > The inner surface of the connecting means 510 may further have raised pieces 517 intended to prevent the connecting bolts 800 from pressing into the ring.
    The mating means 600 comprises a body 610A attached to one end 220 of the roll 200. Attached to the body 610A is a locking pin 615 extending in the transverse direction W of the roll 200. The body 610A of the mating means 610 may comprise a locking pin 613, 614 extending longitudinally to the roll 200 mortgaged. The protrusion portion 613, 614 may comprise two longitudinal L protrusions 613, 614 of the roll 200, whereby a locking pin 615 extending in the transverse direction W of the roll 200 may be secured between the protrusions 613, 614. The locking pin 615 is located in the longitudinal direction L of the roll 200 at a distance from the other end 220 of the roll 200.
    The locking pin 615 protrudes from the opening 514 of the connecting means 510 into the housing 515 of the connecting means 510, forming a lock between the ends 210, 220 of the roll 200 when the ends 210, 220 of the roll 200 are joined together.
    The body 610A of the mating means 610 may comprise a first side body portion 611 abutting the inner surface of the roll 200 and a second side body portion 612 abutting the outer surface of the roll 200. The locking pin 615 of the mating means 610 is located between the projections 613, 614 of the side body portions 611, 612 outside the other end 220. The locking pin 615 is attached to both side poem portions 611, 612. The locking pin 615 extends in the transverse direction W of the roll 200. The locking pin 615 protrudes from the opening 514 of the connecting means 510 into the housing 515 of the connecting means 510 when locking the ends 200, 220 of the roll 200 together.
    The mating means 610 can be attached to the track 200 by bolts and nuts 800 extending through the track 200 and the first side frame portion 611 and the second side frame portion 612. The first side frame portion 611 of the mating means 610 has a first protrusion 613 (not shown) and a second the side frame portion 612 has a second protrusion 614. The protrusions> 613, 614 extend from the center of the body 611, 612 in the longitudinal O direction of the track 200 | outwardly from one end 220 of the roll 200. The other <end 220 of the roll 200 may be flush with the leading edge of the body members 611, 612.
    Attached between the projections 613, 614 is a locking pin 615 which extends in the transverse direction W of the roll 200. The locking pin 615 is located in the longitudinal direction L of the roll 200 2 at a distance 220 from the other end 220 of the roll 200. The locking pin 615 is thus also located in the longitudinal direction L at a distance> from the leading edge of the bodies 611, 612.
    The mating means 610 may comprise a T-shaped body portion. The projections 613, 614 form the vertical spindle of the letter T and
    the tapping pin 615 forms the horizontal spindle of the letter T. The protrusions 613, 614 could also form a lying U-letter. The locking pin 615 would then be attached inside the letter U, to the bottom of the letter U. The ends 210, 220 of the roll 200 can be connected to each other by raising the connecting means 500 and the mating means 600 at an angle of about 30 to 60 degrees to the horizontal. At the same time, the ends 210, 220 of the roll 200 are partially stacked so that the locking pins 615 of the mating means 600 pass through diagonally downwardly directed openings 514 into the housing 515 of the connecting means 510. The projections 613, 614 of the mating means 600 then fit into the slots 516. to the housing 515 of the connectors 510, from which they cannot accidentally slip out. Between the wheels 123, 124 of the bogie 120, inwardly bending forces may be applied to the connection point of the roll 200, e.g. when the branch presses the connection point of the roll 200 inwards. However, the fold does not become so large that the connection of the ends of the roll 200 could open. Figure 5 shows one connecting means 510 and one mating connection means
    610. All connecting means 510, 520 have a similar locking structure based on the opening 514, the housing 515 and the slot 516. All mating means 610, 620 also have a similar locking structure based on the locking pin 615.
