A track-laying gear for bulldozers, loading tractors or the like has a central support frame, running-gear frames which enclose the latter laterally and are mounted on the one hand on support axles which are flush with one another and securely connected to the support frame and on the other hand on a self-aligning bearing bridge which is mounted centrally in the support frame, tracks which run over the end-side track drive and deflection wheels of the travel-gear frames and hydraulic motors which drive the drive track wheels via gears and are fed with pressure medium from hydraulic pumps which are driven by an internal combustion engine arranged in the support frame. In order to connect a track-laying gear unit of this kind to the running-gear frame by means of maintenance-free and impact-absorbing and noise-absorbing bearings, the running-gear frames (2, 3) are mounted (Fig. 1) on support axles (10, 11) by means of elastic bearings (13) whose outer rings and inner rings are connected to one another by means of elastic material. <IMAGE>
