ABSTRACT:
The invention provides a suspension system for track-type vehicles. The system comprises a resilient assembly for mounting on the track roller frame of the vehicle which includes a tubular member having a stack of resilient pads therewithin and a plurality of spaced coaxial resilient members therearound. The mounted assembly effectively cushions relative vertical and horizontal movement between the track roller frame and main frame of the vehicle. An alternate embodiment includes a resilient assembly having a plurality of obliquely oriented resilient pads mounted upon the track roller frame to form a pocket for receiving a complimentary mating bracket secured to the main frame of the vehicle. The assembly effectively cushions horizontal and vertical relative movement between the main and track roller frames of the vehicle.
