Abstract
Abstract A system for supporting roller wheels from the undercarriage of a tracked vehicle having a rubber track. A beam, extending transverse to the axles of the roller wheels mounted thereon, is supported at each end by a resilient suspension element which provides resilient support in the vertical direction and limited resilience to "fore" and "aft" and rolling motion of the beam, and the roller wheels mounted thereon, with respect to the undercarriage
