ABSTRACT:
An impact reducing idler wheel comprises a retaining ring and a tread ring having a pair of mutually-spaced tread surfaces separated by a radially outwardly open annular groove. The retaining ring is positioned within the radially outwardly open annular groove. A first resilient member is disposed between the retaining ring and the tread ring. A central hub is concentric with the tread ring, and a second resilient member is disposed between the hub and the tread ring. The tread ring may comprises a plurality of arcuate segments which are independently movable relative to the hub and the retaining ring.
