Abstract
A suspension system for a track chassis on a vehicle with a rotatable drive axle is disclosed herein. The suspension system includes a track frame, a rotatable drive wheel, a plural number of support bars, a plural number of bogie wheels, and a closed-loop track. The track frame is mounted to the vehicle, and the drive wheel is in rotary communication with the drive axle of the vehicle. The support bars are pivotally attached in independent fashion to the frame, and multiple bogie wheels are rotatably mounted to each of the support bars. The track is looped about the drive wheel and the bogie wheels so as to engage the outer peripheries of the drive wheel and the bogie wheels.

11. A suspension system for a track chassis on a vehicle with a rotatable drive axle, said suspension system comprising:
-
a track frame mounted to said vehicle;
a rotatable drive wheel in rotary communication with said drive axle of said vehicle;
a plural number of support bars pivotally attached in independent fashion to said frame;
a plural number of bogie wheels rotatably mounted to each of said support bars;
a track looped about said drive wheel and said bogie wheels so as to engage the outer peripheries of said drive wheel and said bogie wheels; and
a plural number of shock absorbers respectively connected between said support bars and said frame so that said bogie wheels are biased against the inner periphery of said track for thereby maintaining slack-minimizing tension in said track. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A suspension system for a track chassis on a ground vehicle with a rotatable drive axle, said suspension system comprising:
-
a track frame mounted to said vehicle;
a rotatable drive wheel in rotary communication with said drive axle of said vehicle;
a plural number of support bars pivotally attached in independent fashion to said frame;
a plural number of bogie wheels rotatably mounted to each of said support bars;
