ABSTRACT:
Universally mounted wheelset where an axle housing suspension utilizes a rocking hinge principle to absorb shocks with limited up and down movement. A pair of swivel blocks are connected by trunnions to fore and aft ends of the axle assembly enabling rocking movement of the axle assembly about a longitudinal axis extending generally longitudinally of the direction of movement of the vehicle. One of the swivel blocks is hinged to the vehicle frame. This enables the axle housing to tilt up and down about the hinged swivel block in addition to rocking about the longitudinal axis. Cushioning springs are provided between the vehicle frame and the opposite, tiltable end of the axle assembly. The swivel block at the tiltable end has a pair of transverse horizontal rollers at opposite sides engaged within vertical guide slots formed in mounting blocks fixed to the frame; and it is telescopically supported on the axle housing for limited fore and aft movement to compensate for arcuate movement of the axle assembly as the rollers are guided up and down within the guide slots.
