Abstract
A track assembly for a vehicle includes: a frame; a plurality of track-contacting wheels; an endless track disposed around the track-contacting wheels; a rotation limiting device for limiting rotation of the track assembly relative to a vehicle frame; a connection bracket for connecting the rotation limiting device to the frame; and a bushing assembly slidably connecting a device connecting end of the connection bracket to an elongate support of the rotation limiting device. The bushing assembly includes an inner bushing slidably mounted to the elongate support, an outer bushing affixed to the device connecting end, and a resilient element connected between the bushings. The resilient element is resiliently deformable such that: the inner bushing is rotatable relative to the outer bushing such that an inner bushing axis can be angled relative to an outer bushing axis; and the inner bushing is axially movable relative to the outer bushing.
