Definitions
- This invention relates to vehicle ice and chain traction traction systems which may be both rapidly deployed and rapidly retracted. More particularly, it relates to apparatuses for mounting such systems on vehicles.
- Rapidly-deployable chain traction systems which may be characterized generally as systems which fling short chain or cable segments beneath a road tire, have been known for some 90 years.
- Such a system is disclosed in U.S. Pat. No. 1 ,045,609 and in German Pat. No. No. 266,487 to W. H. Putnam for an ANTISKIDDING DEVICE.
- U.S. Pat. No. 1 ,045,609 and in German Pat. No. No. 266,487 to W. H. Putnam for an ANTISKIDDING DEVICE.
- various modifications and improvements have been made by numerous inventors. The following list is a representative list of a dozen other U.S. patents issued in this field:
- the chain traction system 100 is removably affixed to a drive axle 101 which incorporates a differential unit 102.
- Inner and outer road wheels (103A and 103B, respectively) are mounted on the visible half of the drive axle 101.
- On each road wheel (103A and 103B) is mounted a rubber tire (104A and 104B, respectively).
- the chain system 100 includes a friction drive disc 105 to which a plurality of chain segments 106A, 106B and 106C are attached.
- Chain segment 106A is depicted as being below the road surface 114, which is normally covered with a layer of snow or ice when the chain system 100 is in the deployed configuration.
- the friction drive disc 105 is rotatably mounted on a spindle 107 which is affixed to a support member 108 which is pivotally mounted to a mounting bracket 109.
- the mounting bracket is, in turn, bolted to the U-bolt shackles 113 which secure the suspension leaf springs 112 to the drive axle 101.
- the chain system 100 also includes a pneumatic cylinder 110 that is bolted to the mounting bracket 109.
- the pneumatic cylinder 110 has a slidable piston 111 that is held in a normally retracted position within cylinder 110 by spring biasing when pressure within cylinder 108 equals ambient pressure.
- the outer end of piston 111 is connected to support member 108.
- the outer rim of friction drive disc 105 is pressed against the sidewall of tire 104A by a biasing force applied to support member 108 by piston 111.
- the biasing force is provided by pneumatic pressure inside pneumatic cylinder 110 which overcomes the spring biasing and causes piston 111 to extend.
- the friction drive disc 105 also rotates with the chain segments 106 extended more or less radially therefrom.
- each chain segment 106 is flung, sequentially, beneath the tread portion of tire 104A.
- pneumatic pressure to pneumatic cylinder 110 is cut off, causing piston 111 to retract within cylinder 110 and raising the support member 108, the rotatably attached friction drive disc 105 and the attached chain segments 106.
- the chain segments 106 do not touch the road surface 114.
- the mounting brackets used to attach the rapidly-deployable chain traction system components to the spring shackles must be custom fabricated for each vehicle, as wheel sizes and shackle configurations and suspension geometry dimensions vary from vehicle to vehicle.
- U.S. patent 4,800,992 granted to Olle Andersson and Lennart Carlsson on January 31 , 1989, a unique mounting system is disclosed for rapidly-deployable chain traction systems.
- a cylindrical tube is slidably and rotatably mounted within a pair of clamps attached to the spring shackle bolts.
- the support member which carries the spindle-mounted drive disc at one end, is pivotally mounted at the other end to a mounting plate which is welded to an end of the cylindrical tube.
- the invention is an improved mounting apparatus for chain traction systems installable on wheeled vehicles. Designed for use on vehicles which have a beam or live axle (i.e., one which incorporates a differential), the apparatus mounts to U-bolt shackles which commonly secure the axle to either a set of leaf springs or an air bag assembly. If no U-bolts are present on the axle, a new set of U-bolts may be installed thereon and used to secure the system. In either case, the new mounting system is designed to be mounted directly to the exposed, threaded ends of the U- bolt shackles.
- the new mounting system includes four threaded coupling nuts, each of which is threadably secured to a threaded end of one of the U-bolt shackles.
- a cross plate having a pair of outer apertures and a central aperture ties each lateral pair of coupling nuts together.
- each side of the vehicle employs two cross plates.
- One of the apertures of each cross plate is elongated so that the cross plate may accommodate a range of spacing between U- bolt shackles.
- Bolts are used to attach the cross plates to the coupling nuts.
- a mounting tube of generally square cross section has four apertures aligned along its length. The first two apertures are round and near one end of the tube.
- a mounting plate includes two sets of two holes.
- the holes of the first set which are round, are used to attach the chain traction components.
- the holes of the second set which are elongated, are used for adjustably securing the mounting plate to the mounting tube.
- the mounting bracket of the traction system which corresponds to the mounting bracket 109 of Figure 1 , has been adapted to mount to the mounting plate. It will be appreciated that the elongated apertures in the mounting plate and in the mounting tube permit a great deal of adjustability of the mounting bracket within an x-y plane. The adjustability permits side-to-side movement, back-and-forth movement, as well as a certain amount of pivotal movement for proper alignment of the components. For adjustability up and down movement in a "z" direction, spacers, such as plain flat washers or rectangular spacers having a central aperture, of varying thickness may be inserted between the coupling nuts and the cross plates. The use of spacers may require the use of longer bolts for securing the cross plates to the coupling nuts.
- the parts may be locked in place using a short weld bead where the various adjustable parts join.
- the bead may be ground off to free the parts.
- Figure 1 is a rear elevational view of a typical modern rapidly-deployable chain traction system
- Figure 2 is a side elevational view of a rapidly-deployable chain traction assembly coupled to a vehicle axle via the new mounting assembly.
- Figure 3 is an isometric exploded view of the new mounting assembly for a chain traction system
- Figure 4 is a top plan view of the new mounting assembly of Figure 2.
- Figure 5 is a side elevational exploded view of the new mounting assembly of Figure 2;
- Figure 6 is a top plan view of a rapidly-deployable chain traction system coupled to a vehicle axle via the new mounting assembly;
- Figure 7 is an isometric assembled view of the new mounting assembly.
- the invention is an improved mounting apparatus for chain traction systems installable on wheeled vehicles.
- the particular mounting system disclosed herein is designed for use on vehicles which have a beam or live axle (i.e., one which incorporates a differential) 101.
- the apparatus mounts to U-bolt shackles which commonly secure the axle to a set of leaf springs 112 or an air bag assembly (not shown). If no U- bolts are present on the axle, a new set of U-bolts may be installed thereon and used to secure the system.
- the new mounting system is designed to be mounted directly to the exposed, threaded ends of the U-bolt shackles, coupled to two sets of leaf springs (see 112 of Fig. 1).
- Each leaf spring set is coupled to the beam axle or axle housing (in the case of a live axle) with a pair of U-bolt shacklesl 13, which are tied together beneath the axle or axle housing with a flat tie plate 114 that is secured with four standard nuts 115 (two on each U-boit).
- the new mounting system is designed to be mounted directly to the exposed, threaded ends of the U-bolt shackles 113.
- the new mounting system 200 includes four threaded coupling nuts 201 , each of which is of sufficient length to engage a threaded shaft or bolt shank at each end thereof.
- Each of the coupling nuts 201 is threadably secured to a threaded end of one of the U-bolt shackles 113.
- the mounting system 200 further includes, for each side of the vehicle, a pair of cross plates 301.
- Each cross plate 301 has a pair of outer apertures 302A and 302B for securing the plate to a pair of coupling nuts 201 , and a round central aperture 303.
- One of the outer apertures 302B is elongated so that the cross plate 301 may accommodate a range of spacing between U-bolt shackles 113.
- Four coupler bolts 304 are used to anchor the cross plates 301 to the free ends of the coupling nuts 201 , which are attached to the U-bolt shackles 113.
- a tube 305 of generally square cross section has four apertures aligned along its length.
- the first two apertures 306A and 306B are round and are near one end of the tube 305.
- the other two apertures 307A and 307B are elongated for adjustably attaching the tube 305 to the round central apertures 303 of cross plates 301.
- a mounting plate 310 includes two sets of holes 311 A and 311B.
- the holes 311A which are used for mounting the traction system, are round.
- Mounting bolts 312 and mounting nuts 313 are used for this purpose.
- the holes 311 B which are used for adjustably securing the mounting plate 310 to the mounting tube 305, are elongated.
- Securing bolts 314 and securing nuts 315 are used for securing the mounting plate 310 to the mounting tube 305.
- the mounting bracket 601 of the traction system 600 which corresponds to the mounting bracket 109 of Figure 1 , has been adapted to mount to the mounting plate 310.
- the elongated apertures in the mounting plate 310 and the mounting tube 305 permit a great deal of adjustability of the mounting bracket 601 with an x-y plane.
- the adjustability permits side-to-side movement, back-and-forth movement, as well as a certain amount of pivotal movement for proper alignment of the components.
- spacers such as plain flat washers, of varying thickness may be inserted between the coupling nuts 201 and the cross plates 301. If spacers are used, longer coupler bolts 304 may be required.
- Figures 7 and 8 provide a more clear view of the actual shape of the mounting plate 310, the mounting tube 305 and the cross plates 301.
- the parts may be locked in place using a short weld bead where the various adjustable parts join.
- the weld beads serve only a locking function, as the bolts and nuts remain securely tightened.
- the bead may be ground off to free the parts.
