<p>An air suspension system for the front, steer axle (12) of a vehicle comprising: a pair of rearwardly extending leaf springs (18) associated at their rear ends with the axle (22), a forward end of each spring being mounted to chassis frame members of the vehicle, a pair of clamp blocks (28, 29) engaged about each spring rearwardly of the forward end, one of the clamp blocks of each pair having a transversely extending channel (30) forming a seat for an axles thereby locating the axle relative to each spring, the leaf springs extending rearwardly of the axle to form mountings for airbags (24, 25) which extend between the spring and a respective vehicle chassis frame member, at least one air bag operatively associated with each spring to control relative movement between the axle and the respective vehicle chassis frame member, a high flow-rate air tube (26) connected to the at least one air bag, air flow controlling means between the high flow-rate air tube and the air bag, the high flow-rate air tube forming a manifold (50) to which air is passed in a manner that is substantially un-regulated by the air-flow controlling means when air pressure in the air bag increases above that in the manifold, and air pressurising/exhausting means connected to the manifold through a low flow-rate air tube (38) to maintain a required pressure therein to thereby maintain a selected, predetermined vehicle ride height.</p> |
