The cleat includes (i) a body with downwardly extending, inwardly facing and laterally spaced end hooks, wherein at least one of the end hooks is laterally repositionable relative to the other end hook as between an open position and a closed position, (b) at least one projection extending upward from the body effective for biting engagement with a supporting surface, and (c) a manually operable repositioning assembly for reversibly driving the at least one laterally repositionable end hook towards the other end hook, whereby the body may be clamped onto a rubber track on a mobile construction unit.

Abstract: An individual replacement drive or guide lug for missing or worn lugs located on an inner circumference of various endless rubber tracks used on multi-surface vehicles. The lug comprises a body and a fastening including a bolt and washer. To install the drive lug properly, an inner surface of the track where the original vulcanized rubber drive lug was located must be prepared. When the original drive lug fails, it leaves an irregular surface and must be ground flat with the inner track belt substrate. The bolts are then secured through the track and the lug so as to removably secure the lug to the inner surface of the track.

Abstract: A track shoe fastened on a chain of the caterpillar vehicle includes a body and a buffer block. The body includes an first surface adjacent to the chain, a second surface opposite to the first surface, a third surface, a fourth surface opposite to the third surface, a groove defined on the second surface and through the third surface and the fourth surface, and the holes defined through the first surface and the second surface to communicate with the groove. The buffer block includes an embedded portion capable of being embedded within the groove of the body, and multiple lock holes defined through the buffer block to respectively communicate with the holes of the body. The buffer block is secured on the body through the embedment between the embedded portion and the groove, and secured on the chain by the fastening members within the holes and the lock holes.

Abstract: An endless track for use with a vehicle, including a primary track section and at least one paddle is provided. The primary track section includes an upper surface, a lower surface, a first outer side and a second outer side. The paddle includes a first end and a second end, where the first end is operatively connected to the primary track section adjacent one of the sides. The paddle is non-perpendicular with respect to the primary track section such that the second end of the paddle is positioned outwardly away from the primary track section.

Abstract: A method and apparatus for producing bent snowmobile studs for use in an assembly are disclosed. The assembly comprises a bent stud having a head and proximal and distal shank portions and a fastener which is adapted to connect with respect to the distal shank portion of the stud. The head and shank of the stud are engaged by members which are mechanically pivoted with respect to one another such that the shank is bent. The assembly prevents rotational movement between the stud and the track.

Abstract: A grouser structure for use on an outer surface of a continuous track belt to provide traction and shock absorption, the grouser structure including a grouser body that defines a grouser chamber and a spline element positioned within the grouser chamber. In one preferred embodiment a shock absorption gap is formed between the inner chamber peripheral surface and the outer spline peripheral surface. In another preferred embodiment the base of the grouser body is solid or contains other structure to prevent the first body side leg and the second body side leg from spreading. In yet another preferred embodiment the spline element is a solid reinforcement spline element. In still another preferred embodiment the spline element is associated with an extension section to which an ice cleat may be functionally attached.

Abstract: A traction device for mounting on an endless track includes these components: an axial threaded shank with a head at one end, a T-nut with a base and a neck extending from the base, so that the neck is mountable on the shank, with the base at the shank head, a washer plate threadably fastenable on the T-nut on the shank, and a stud threadably mountable on the washer plate on the shank, to fasten the stud to the shank. The endless track is positioned between the T-nut and the back plate, with the shank extending through an opening in the track. A stud for a traction may be metal or nonmetal, such as composite with a metal insert. A paddle is mountable on a plurality of traction device pediments across a width of the track.

Abstract: A molded plastic retainer for supporting a spiked vehicle stud. In a construction useable with snowmobile studs, a ground engaging surface includes a self threading center bore and concentrically disposed to which are a raised, hexagon tool surface and a number of pointed secondary, traction enhancing studs. A track engaging surface of the retainer includes a tapered recess concentric to the stud receiving bore and a number of projections which enhance the grip between the retainer and track without squeeze out or tearing. Alternative configurations and mounting arrangements of the secondary studs and gripping projections are disclosed and some of which provide multi-faceted surfaces.

Abstract: A roller belt arrangement for a track-type vehicle has pull-resistant belts with a first surface and a second surface opposite the first surface. Drive members are connected to the first surface of the pull-resistant belt so as to extend transverse to a longitudinal extension of the at least one pull-resistant belt. U-shaped members, having a stay and two legs defining a cavity therebetween, are positioned on a second surface opposite the drive members such that the stay rests on the second surface. Cushion members are positioned in the cavity of the U-shaped members. Screw bolts for connecting the drive members to the pull-resistant belt are provided. The screw bolts extend sequentially through the cushion member, the stay of the U-shaped member, the pull-resistant belt, and the drive member. The screw bolts are directly threaded into the drive members.

Abstract: A traction point for a snowmobile track includes a fastener that extends through the track with a head on one side of the track, and a pointed nut that has a pointed end and which is threaded onto the fastener on the opposite side of the track from the fastener head. The traction point includes a base for support on the track, and pyramidal shaped reinforcement gussets that merge at a point to provide for increased traction for the snowmobile. Small ribs can be provided on the traction point for engaging the track to reduce the likelihood of the traction point unthreading and coming off during use. The pyramid shaped flanges give a paddle effect as they engage ice or snow to provide increased surface area for reaction of the driving forces from a snowmobile transmitted through the track, and also increased corner traction and braking effect.
