Traction assembly for a vehicle

Abstract

This invention relates to a traction assembly for a vehicle which uses an endless traction band and a plurality of wheels for propulsion. The traction assembly pivots around a pivot point located under the traction axle of the vehicle. This pivot point is preferably longitudinally displaced in relation to such axle.

1 . A traction assembly for use on a vehicle having a frame, at least one traction axle and at least one suspension leg coupled to said at least one traction axle, said assembly comprising a sprocket wheel adapted to be coupled to said axle, a longitudinally extending support structure and a traction band tensioned around and cooperating with said sprocket wheel and said support structure, said traction assembly further comprising a member having a first end adapted to be fixedly mounted to said at least one suspension leg and a second end pivotally mounted to said support structure at a first pivot point wherein said first pivot point is located under a rotation axis of said sprocket wheel whereby said support structure can pivot around said first pivot point.
