Abstract: A replaceable composite tread ring for a track roller assembly of a track-type vehicle includes a non-metallic outer tread portion and a metallic inner base portion. The metallic base portion is C-shaped and encloses portions of the non-metallic tread. Conventional track roller assemblies have non-replaceable metal tread portions which produce considerable wear on the mating link rails. The subject composite tread ring prolongs the useful life of the link rails by reducing the wear of the rails, since the rails contact the non-metallic portion of the tread ring.

Abstract: A track roller assembly supports and guides the link rails of the endless track of a track-type vehicle as the endless track travels along the ground. Contact between the link rails and the roller assembly is at the tread portion of the roller. A replaceable tread ring on the roller tread portion has a non-metallic outer tread portion which contacts the link rails. The tread ring is held in place by a replaceable flange plate. A separate seal plate holds the various seals in place when the flange plate is removed for replacement of the tread ring or the flange plate. Conventional track roller assemblies have non-replaceable flange plates and metal tread portions which produce considerable wear on the mating link rails. The subject roller assembly prolongs the useful life of the link rails and provides an easily replaceable flange plate and tread ring.

Abstract: A steering control system is provided in which one pair of wheels of an articulated steer vehicle are steered in synchronization with the articulation steering. This is accomplished by providing a first two-position valve for directing the fluid exhausted from the rod end of one articulation steer jack to the head end chamber of one of the rear wheel steering jacks and to the rod end chamber of the other rear wheel steering jack for steering the rear wheels in a first direction and another two-position valve for directing the fluid exhausted from the rod end chamber of the other articulation steering jack to the rod end chamber of the one rear wheel steering jack and the head end chamber of the other rear wheel steering jack for steering the rear wheels in the opposite direction. The rod end and head end chambers of the rear wheel steering jacks are sized in relation to the rod end chambers of the articulation steering jacks so that the steering angle of the rear wheels is synchronized with the articulation steer angle even though the articulation steering jacks are much larger than the steering jacks for the rear wheels.

Abstract: During the operation of a track-type machine in abrasive terrain, it is common to have foreign material deposited between the engagement surfaces of a track chain assembly. The presence of this foreign material between these surfaces has been known to greatly accelerate the wear between these components. The present invention provides a pair of deflecting plates that are positioned adjacent and in overlying relation to certain engagement surfaces of various components of the track chain assembly 14. The deflecting plates direct foreign material away from contact with the engagement surfaces and thereby reduce the wear of the track chain components.

Abstract: An endless track assembly for a track-type vehicle comprises a plurality of track shoes secured to an articulated chain. The links of the chain are pivotally interconnected together by pin and bushing assemblies adapted to engage a drive sprocket of the vehicle. A cushioning lug is secured to each track shoe, intermediate each pair of adjacent pin and bushing assemblies, for attenuating the noise level of the track assembly upon its engagement with the drive sprocket and for aiding in cleaning the sprocket. Each cushioning lug assembly comprises a resilient cushioning block composed of an elastomeric material, a cap mounted on the cushioning block and offset arcuate bearing flanges and a cleaning flange formed integrally on the cap.

Abstract: A hydrostatic mechanical transmission is disclosed having an infinitely variable split torque, planetary drive unit driving a set of range gears, in part mechanically and the remainder through a hydrostatic path comprising variable displacement hydrostatic devices acting alternately as a pump or motor and controlled through a system of hydraulic valves utilizing the same fluid as the hydrostatic devices. Five forward and two reverse ranges are provided in a relatively small package. Control is effected through a manually operated shift lever providing control signals to both the variable displacement hydrostatic devices and range selector unit, with appropriate control and safety features being provided to assure positive and smooth range changes, to prevent reverse rotation in the hydraulic unit, to sense a zero speed condition in the hydraulic units, and to insure positively synchronizing and matching speed conditions for gear engagement.
