Abstract
A vehicle suspension comprises an axle supported at each end by a respective axle box and respective spring means acting between each axle box and an associated rigid vehicle mounting. The spring means has an effective spring center which acts at a point between the axle center and the associated axle box so as to reduce the radius of operation of the suspension in a yaw condition as compared with conventional suspensions in which the effective spring center acts at the axle box. The spring means comprises a pair of spring units arranged one on each side of the axle and each spring unit comprises layers of elastomeric material sandwiched between reinforcement elements.
