Title: Improvements in or relating to vehicle suspensions
IPC: B60G15/06
Filed: 1966-04-18
Abstract: 1,100,098. Self-levelling suspension legs. ALFRED TEVES MASCHINEN-UND ARMATUREN FABRIK KOMM.-GES. 18 April, 1966 [2 Aug., 1965], No. 16846/66. Heading F2S. [Also in Division B7] A self-levelling suspension leg comprises a piston 34 which is connected through a rubber metal mounting 1 to a vehicle body and which, with a cylinder 33, encloses an hydraulic jacking chamber 31 which receives liquid pumped by a plunger 21 a helical coil spring 24 being constrained between spring cups 4, 27 carried respectively by the upper end of the cylinder 33 and the base of a reservoir tube 28 which is guided over an extension 29 of the cylinder 29. Downward motion of a stem 16, which extends downwardly from the piston 34 and which dips into the liquid 23 in the reservoir 28, causes liquid to flow past a valve 20 and into a bore 19, the pump plunger 21 urging the liquid on past a valve 32 and a bore 32 into the chamber 31 to expand the latter, the spring 24 being compressed to balance the load while the vehicle body is maintained at a constant height from the ground. Extension of the unit causes a sleeve 17, which keeps a spring 18 compressed, to withdraw a valve 12 from a valve port 7 so that liquid can pass from the chamber 31 through a port 10, the hollow space 8 within the piston 34, the bore 19, and a bore 22 in the plunger 21 to the reservoir 28, the plunger 21 being disengaged from a seal 26 so that it ceases to pump. A ring 23 on the stem 16 limits the extension of the suspension leg, e.g. when the vehicle is unloaded. The construction includes gaiters 2, 15, and a cap 3 which closes the upper end of the hollow piston 34, the lower spring cup 27 being connected to the reservoir by a resilient member 25. The seal 26 may be replaced by a conical peg, not shown. In a rear axle suspension system, Figs. 5, 6, not shown, 60-75% of the weight of the vehicle body is borne by two helical springs (36) which, with their associated dampers 37, are connected between the vehicle chassis and struts (35) which carry the axle (38) at their rear ends and have their forward ends pivoted to the vehicle chassis, the axle also being connected to the chassis by a triangular link (39). The rest of the resilient force is provided by a self-levelling system (24) which is according to the present invention and which is disposed in the centre of the axle (38). The rear instantaneous centre, Fig. 7, not shown, is lowered to (44) and the axis of instantaneous rotation is lowered to (42) due to the extra spring of the system (24).
