ABSTRACT:
An axle assembly has a longitudinal pivotal connection to a vehicle frame enabling it to rock about a longitudinal axis extending generally longitudinally of the direction of movement of the vehicle. One of the fore-and-aft ends of the axle assembly is hinged to the frame by a universal joint connection consisting of a ball and socket enabling completely unrestricted tilting, swinging and rocking movement of the axle assembly in all directions relative to the frame. At the opposite end, the axle assembly is freely tiltable up and down about a connection to the frame enabling free vertical movement of the tiltable end of the axle assembly while restraining horizontal movement. Springs support the vehicle frame at opposite sides of the axle assembly. Shocks applied through wheels on the axle assembly are absorbed by unrestricted rocking movement of the axle assembly about the longitudinal axis accompanied by up and down tilting movement, both of these movements being about the universal joint connection within a range permitted by the springs. The invention is applicable to non-railway vehicles, as well as to the railway type vehicles shown.
