Abstract
An axle housing has a longitudinal pivotal connection to the frame enabling it to rock about an axis extending generally longitudinally of the direction of movement of the vehicle. One of the fore and aft sides of the axle housing has a transverse pivotal connection to the frame enabling the axle housing to tilt up and down, in addition to rocking about the longitudinal pivotal connection. Spring means support the frame at the opposite side of the axle housing. The combination of rocking about the longitudinal pivotal connection, and up and down tilting about the transverse pivotal connection, absorbs shocks due to irregularities in the track or ground. The invention is applicable to non-railway vehicles, as well as the railway-type vehicles shown.
