Abstract
A guided vehicle having a body with rubber-tired steerable running wheels mounted on axles. A suspension system for the axles includes transversely extending upper and lower link arms which are parallel with each other and have equal arm lengths. Each of the links or link arms has one end connected with the wheel axle through a joint mechanism for a steering movement and a rotative movement about a longitudinal axis and its other end connected at two longitudinally spaced portions with the vehicle body for rotative movement about a second longitudinal axis. Air springs are disposed between one of the links and the vehicle body for normally maintaining the links substantially horizontally to thereby maintain the associated wheel always vertical.
Claims8
An automatically guided vehicle comprising a body and rubbertired steerable running wheels, each having an axle, a suspension system including transversely extending upper and lower link arms which are parallel with each other and have equal arm lengths, each of said links having one end connected with the wheel axle through universal joint means at least for steering movement about a vertical axis and a rotative movement about a longitudinal axis and the other end connected at two longitudinally spaced portions with the vehicle body for rotative movement about a second longitudinal axis, at least one of the link arms being connected with the vehicle body at said longitudinally spaced portions for independent transverse adjustments, air spring means disposed between one of the links and the vehicle body for normally maintaining said links substantially horizontally to thereby maintain the associated wheel always vertical.
