Abstract

An improved mounting system is provided for the chain friction system that can be installed in a vehicle. Designed for use in vehicles with beams or axles, the device is coupled to the threaded ends of the U bolts that secure the axles to a pair of leaf springs or airbag assemblies. For installation on the side of the vehicle, the new mounting system has four coupling nuts that are coupled to the threaded ends of the U bolts. A cruciform metal plate with a pair of outer holes and one center hole secures each side of the coupling nut. Thus, each side of the vehicle uses two cross-shaped metal plates. One hole in each metal plate is lengthened so that the cross-shaped metal plate can adjust the range of the gap between the U bolt shackles. Bolts are used to attach a cruciform metal plate to the coupling nut. In general, the square tube's mounting tube has four holes aligned in length, with the first two holes round and close to one end of the mounting tube, and the other two holes are the center holes of the two cruciform metal plates, with bolts and nuts It is long because it is attached to be adjustable. One mounting plate has two sets of two holes. The first set of holes is round and used to attach to the chain friction component and the second set of holes is long and used to securely mount the mounting plate to the mounting tube. The mounting bracket of the friction system has been adapted to be installed on the mounting plate. It is appreciated that the elongated holes in the mounting plate and mounting tube allow large adjustment of the mounting bracket in the X-Y coordinate plane. The tunability allows movement to the sides or back and forth as well as the movement of a fixed amount of axis for proper arrangement of the components. Spacers of varying thickness will fit between the coupling nut and the cruciform plate to adjust the up and down movement in the van direction. In order to provide a freely movable installation with proper adjustment of the components, the parts will be fixed using short welding beads where there are various adjustable parts.

US Pat. No. Des. 286,524 for ANTISKID CHAIN UNIT FOR VEHICLE TIRES FIG. 1 shows a rear view of a state-of-the-art rapid deployment chain towing system 100 as a conventional system. The chain tow system 100 is attached to the axle 101 which is coupled to the differential device 102 for removal. The inner and outer road wheels 103A and 103B are provided on the visible half of the axle 101. Rubber tires 104A and 104B are mounted on the road wheels 103 and 103B, respectively. The chain towing system 100 includes a friction drive disk 105 to which a plurality of chains 106A, 106B and 106C are attached. Chain 106A is shown to be under road surface 114, usually covered with snow or ice when chain tow system 100 remains deployed. The friction drive disk 105 is attached to the spindle 107 so that it can rotate. The spindle 107 is fixed to the support member 108 pivotally mounted to the mounting bracket 109. The mounting bracket 109 is bolted to the U bolt 113 which fixes the suspension leaf spring 112 to the drive axle 101. The chain towing system 100 also includes an air cylinder 110 bolted to the mounting bracket 109. The air cylinder 110 has a sliding piston 111, which is usually retracted into the cylinder by a spring when the pressure in the cylinder 110 is equal to the ambient pressure. The outer end of the piston 111 is connected to the support member 108. In the deployed state, the outer rim of the friction drive disk 105 is pressed against the tire 104A sidewall by a biasing force applied to the support member 108 via the piston 111. This deflection force is generated by the internal air pressure of the air cylinder 110 which extends the piston 111 by overcoming the force of the spring. As the tire 104A rotates, the friction drive disk 105 also rotates with the chain 106 extending radially from the disk. Therefore, each chain 106 enters under the threaded portion of the tire 104A. To retract the system and separate the contact between the friction drive disk 105 and the sidewall of the tire 104A, the air pressure of the air cylinder 110 is cut off, the piston 111 is retracted into the cylinder 110 and the support member 108 is removed. , The friction drive disk 105 and the chain 106 are raised. In the retracted state, the chain 106 does not touch the road surface 114. Mounting brackets used to attach the fast-developing chain towing system components to the spring clasps typically vary in size, wheel configuration, suspension form, etc. per vehicle. Different cars have to be customized differently. U.S. Patent 4,800,992, issued to Olle Anderson and Lennart Carlsson on January 31, 1989, describes a unique mounting system for a fast-developing chain tow system. In a pair of clamps attached to the spring latch bolt, the cylindrical tube is mounted to be slidable as it rotates. The other end of the support member for supporting the spindle-mounted drive disk at one end is pivotally mounted to the mounting plate, and the mounting plate is welded to one end of the cylindrical tube. This arrangement allows for a large adjustment. When installed, the clamps remain loose to some extent until the towing parts are aligned by the cylindrical tube. Once properly aligned, tighten the clamp to secure the cylindrical tube in a fixed position. The system has greatly improved the ease of installation by minimizing custom parts, but there are some inconveniences. First, the cylindrical tube can rotate in use no matter how tight it is. Second, the range of adjustment is not ideal. In addition, even if the position is maintained along the sliding axis without changing the direction, it is difficult to adjust the effective height. If the mounting plate was welded away from the central axis of the cylindrical tube, the height of the system could be adjusted by the rotation of the cylindrical tube. However, the installation of the long pack off center increases the torque about the axis of the tube, increasing the likelihood that the tube will rotate during use. In addition, system height adjustment by the rotation of the tube changes the direction of the angle of the components.

Therefore, there is a need for a new type of mounting system for a fast-developing chain tow system that is easy to adjust and that allows traction components to be adjusted about three axes without changing the angle, but which does not change relative alignment during operation.

This invention is an improved mounting device for a chain tow system that can be attached to a vehicle. Designed for automobiles with beams or drive axles (implementing a differential), they are usually mounted on U bolts that secure the axles to a leaf spring or airbag assembly. If the U bolt is not on the axle, a new set of U bolts can be installed and used to secure the system. Either way, the new mounting system is designed to mount directly on the exposed threaded end of the U bolt. For installation on each side of the vehicle, the new mounting system has four coupling nuts that screw into one of the threaded ends of the U bolts. The coupling nuts are fixed side by side by means of a cross plate having a pair of outer and one center holes. Therefore, two cross plates are used on each side of the vehicle. One of the holes in each cross plate is elongated to accommodate the gap between the U bolts. Bolts are used to join the cross plate to the coupling nut. In general, a square cross-section mounting tube has four holes aligned along its length, with the first two holes rounded and near one end of the tube, and the outer two holes bolted to the center hole of the two cross plates. Long to fit properly with nuts. Two pairs of holes are formed in one mounting plate. The first pair of holes is circular and is used to join the chain towing elements. The second pair of holes is elongated and is used to properly secure the mounting plate to the mounting tube. The mounting bracket of the traction system corresponding to the mounting bracket 109 of Figure 1 is suitable for mounting on the mounting plate. Elongated holes in the mounting plate and mounting tube allow for large adjustment of the mounting bracket in the XY plane. This ability to move back, forth, left and right as well as to some degree of pivoting movement allows the parts to be properly aligned. In order to adjust the height in the z-direction, spacers such as flat washers or rectangular spacers having various thicknesses having a hole in the center may be inserted between the coupling nut and the cross plate. If spacers are used, longer bolts should be used to secure the cross plate to the coupling nut. Once the parts are properly adjusted so that there is no movement after mating, they can be held in place using short weld beads on the various joints. For AS, these beads should be able to be disassembled.

The present invention is an improved mounting apparatus of a snow chain traction system that can be attached to a vehicle. 1 and 2 a special mounting system is designed for use in a vehicle with an axle 101 (implementing a differential device). On the side of the vehicle, the device is typically attached to a U bolt that secures the axle to a leaf spring 112 or an airbag assembly (not shown). If the U bolt is not on the axle, a new set of U bolts can be installed and fixed. Either way, the mounting system is designed to be mounted directly to the exposed threaded end of the U bolts connected to the two pairs of leaf springs 112. Each leaf spring is connected to the axle or axle housing by a pair of U bolts 113, and the U bolts are coupled to the axle or axle housing together with a coupling plate 114 fixed by four standard nuts 115 (two on each U bolt). It is fixed like below. The new mounting system is designed to attach directly to the exposed threaded end of the U bolt. 2, 3, 4, and 5, on the side of the vehicle body, the mounting system 200 has four threaded coupling nuts 201, each coupling nut having a length sufficient to be coupled to the bolt. Have Each coupling nut 201 is screwed with the U bolt 113. The mounting system 200 further includes two cross plates 301 for each side of the vehicle body. Each cross plate 301 has bilateral two holes 302A and 302B for fixing to the coupling nut 201 and one central hole 303. One hole 302B is long enough that the cross plate 301 can accommodate the gap between the U bolts 113. Four coupling bolts 304 are used to fix the cross plate 301 to the free end of the coupling nut 201 coupled to the U bolt 113. Four holes are aligned along the length of the mounting tube 305 having a square cross section. The first two holes 306A, 306B are circular and located near one end of the mounting tube 305. The other two elongated holes 307A and 307B are elongated so that the mounting tube 305 is properly engaged with the round intermediate hole of the cross plate 301. A coupling bolt 308 and a coupling nut 309 are used to connect the mounting tube 305 to the cross plate 301. The mounting plate 310 has two pairs of holes 311A and 311B. The hole 311A used to mount the friction system is round, and mounting bolts 312 and mounting nuts 313 are used here. The hole 311B used to properly secure the mounting plate 310 to the mounting tube 305 is elongated. A fixing bolt 314 and a fixing nut 315 are used to fix the mounting plate 310 to the mounting tube 305. 2 and 6, it can be seen that the mounting bracket 109 of the traction system corresponding to the mounting bracket 109 of FIG. 1 is suitable for mounting on the mounting plate 310. Elongated holes in the mounting plate 310 and mounting tube 305 allow the mounting bracket 109 to be significantly positioned in the x-y plane. This positioning allows the mounting bracket to move side to side, front to back, left and right, as well as to some extent pivoting so that the parts can be properly aligned. In order to adjust the height in the z direction, spacers 316 such as flat washers having various thicknesses may be inserted between the coupling nut 201 and the cross plate 301. If spacers 316 are used, longer coupling bolts 304 are needed. 7 and 8 show the actual shape of the mounting plate 310, mounting tube 305, cross plate 301 in more detail. To ensure that the equipment does not move, after making certain component adjustments, hold these parts in place using short weld beads on the various component connections. The weld bead simply locks in because the bolts and nuts are tight. For AS, it is good practice to separate the weld beads so that the parts can be disassembled. As mentioned above, although an example of the rapid-action chain traction system mounted on a vehicle has been described, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention as set forth in the appended claims.
