Patent ID: 7036805

Claim:
A pneumatic front suspension assembly for an industrial vehicle, comprising: a front axle linked to a pair of side members; a pair of air bags for adjusting height of the axle relative to the side members; and, on each side: a rigid arm, of which one extremity is articulated relative to a side member and of which an other extremity receives the axle and a bottom part of one of the air bags; a pair of links mutually articulated about a pin substantially parallel, to the axle, an upper link of the pair of links, being articulated relative to the side member, a lower link of the pair of links being articulated relative to the rigid arm, the pair of links absorbing transverse loads so as to substantially eliminate transverse movements of the axle during vertical motions of the axle without resort to or inclusion of a transverse link between a side member and the axle; and a basically U-shaped additional element forming an anti-roll bar, comprising: a transverse rod mounted between a bottom extremity of each lower link at an articulation point of the lower link with the rigid arm; and branches located on either side of the transverse rod, and linked to a respective lower link.
