<p>VEHICLE SUSPENSION 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 centre which acts at a point between the axle centre 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 centre acts at the axle box. The yaw stiffness of the suspension is thereby reduced enabling the axle to self-align radially as the vehicle traverses tight curves and avoid wheel slip. 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.</p> |
