ABSTRACT:
A tracklaying undercarriage for bulldozers, crawler loaders or other tracklaying vehicles including a central main frame and two tracklaying frames disposed on opposite sides of the main frame. The tracklaying frames are mounted at one end on mutually aligned supporting axles, which are fixed to the main frame, and at the other end on a rocker bridge, which is pivoted at its center to the main frame. The undercarriage also includes track chains, which are trained around driving and reversing chain sprockets mounted at mutually opposite ends of the tracklaying frames, and rotary hydraulic motors for driving the driving chain sprockets. The motors are supplied with fluid by hydraulic pumps, which are driven by an internal combustion engine mounted on the main frame. The tracklaying frames are mounted on the supporting axles by means of elastic bearings, which have outer and inner races that are interconnected by elastic material.
