Abstract
1,166,556. Adjusting vehicle suspension height. FORD MOTOR CO. 25 Feb., 1967, No. 9121/67. Heading B7D. [Also in Division B8] When the sprung part of a vehicle is lowered relatively to the unsprung part to facilitate loading and unloading, the sprung-part rests on the tyres of the road wheels to inhibit movement of the vehicle. An axle 3 carrying road wheels 4 is connected to a chassis 2 carrying a load platform 1 by bell-crank levers 6, 7 splined to the ends of a torsion rod 8 which is rotatable in mountings 9 beneath the chassis 2 and acts as an anti-roll bar. Air springs 10, 11 acting on each lever 6, 7 are connected to a reservoir 14 through non-return valves (not shown), a control valve 15 and restrictors 17. The control valve 15 includes a spool which in a first position exhausts the reservoir and springs 10, 11 to facilitate servicing, in a second position pressurizes the springs 10, 11 from the reservoir 14 for normal running, in a third position exhausts the springs 10, 11 to lower the platform 1 on to the tyres 5 of the road wheels 4, and in a fourth position traps pressurized air in the springs and reservoir so that the system can be tested for leaks. Additional air springs acting on the levers 6, 7 in opposition to the springs 10, 11 may be pressurized during loading and unloading so that the platform 1 compresses the tyres 5 to further reduce the loading height. In other embodiments the chassis 2 is suspended by laminated or torsion bar springs and is lowered by an electric motor which may be protected by an overload clutch.
