ABSTRACT:
A wheeled undercarriage unit (10) adapted to replace a tracked unit comprises elongate hollow side frames (12, 14) rigidly interconnected by cross frames (16, 18). Six wheels (20, 22, 24, 26, 28, 30) are rotatably supported in pairs on the side frames (12, 14). The wheels on each side of the unit (10) are drivingly interconnected by chain and sprocket transmissions located within the side frames (12, 14). The drive means for the wheels (20, 22, 24, 26, 28, 30) are located between the side frames (12, 14) and cross frames (16, 18). The middle wheels (22, 28) extend below a plane lying tangent to the end wheels (20, 24, 26, 30) to facilitate skid steering. Mounting pads (96) are provided for attaching a mechanism to the undercarriage unit (10). In addition to the capability of operating over adverse terrain, a vehicle incorporating the unit (10) can be operated over a paved surface without the damage thereto that would be caused otherwise by a tracked unit.
