In a track type vehicle having a body with forward and rearward ends, steering means mounted at the forward end, an endless flexible reinforced elastomeric track having an inside surface and ground engaging outside surface positioned on the longitudinal axis of the vehicle for propelling the vehicle, motor and drive means mounted on said body for engagement with and to drive the track, a suspension system associated with the track and the vehicle body comprising: a framework having forward and rearward ends positioned on the longitudinal axis and within the inside pathway of the track; mounting means connected on either side of the framework at the forward and rearward ends for attaching the framework to the vehicle body; a first axle and pulley means mounted at the forward end of the framework; a second axle and pulley means mounted at the rearward end of the framework; means at the rearward end of the framework for mounting track engaging pulleys and positioned outside and rearwardly of the second axle pulleys; and at least one endless belt mounted between the first and second axle pulleys and engaging the track on its bottom inside surface so as to be driven at substantially the same speed as the track; said vehicle track having drive lugs on its inside surface and said belt mounted between first and second axial pulleys comprising high modulus tensile cords embedded therein nearer the inside surface, and a layer of substantially incompressible material forming the outside surface, said belt having a plurality of notches formed therein in an alignment and sequence to receive and interlock with the drive lugs on the inside surface of the track, said interlocked suspension belt notches and track drive lugs and the separation of the tensile cords of both the belt and track combining to effect a resistance to back-bending such that the track conforms to the terrain over which it passes.
