Abstract

388,506. Road-vehicle suspension; hydraulic shock - absorbers. LANDEWEER, K., 74, Biltstraat, Utrecht, Holland. Nov. 25, 1931, No. 32735. Convention date, Jan. 21. [Classes 108 (ii) and 108 (iii).] With the object of preventing lateral tilting of the body and frame of a vehicle relatively to the axles, fluid shock absorbers of the oneway type are rendered double acting when the vehicle is tilted or is subjected to forces tending to tilt it. In the construction shown in Fig. 1, cylinders 1, 2, mounted on opposite sides of the vehicle are each provided with pistons 3, 4 connected to opposite ends of the axle and each having a small leakage orifice 7, 8. Opposite ends of the cylinders are connected by pipes 9, 10 with one-way valves 11, 12, which allow upward movements of the pistons but check downward or rebound movements. The connections 9, 10 are further provided with cocks 13, 14 which are normally open but may be closed by rods 17, 18 when a pendulum 28 swings to one side or the other under the action of centrifugal or other forces, so that one of the shock absorbers opposes downward movements of the frame. In a modification an inverted pendulum held centrally by a spring operates the cocks 13, 14 through electric relays In a further modification each cock is operated by linkwork connecting it to the piston-rod on the opposite side of the vehicle. In the modification shown in Figs. 4 and 5, two shock absorbers each constructed as shown in Fig. 5, are arranged on opposite sides of the vehicle and are cross connected by pipes 83, 84. In each case a rocking lever 69, 70, actuated by an arm 57, 58, connected to the axle, operates two pistons 63, 64, having large one-way valves 65, 66, which allow relatively free upward movement. Downward movement of the pistons is retarded by throttling devices consisting of grooved or hollow stems 72, 73. The interior of the hollow stem 73 communicates with its cylinder through throttling orifices 75 which may be more or less closed by a movable stem on a piston 79, the lower end of which is subjected to pressure transmitted from a cylinder on the opposite side of the vehicle. A spring 82 opposes the fluid pressure. As long as the frame and axle remain parallel to one another upward and downward movements on each side of a vehicle are restrained by forces which depend upon leakage through the groove 72 or the port 75 and also upon the spring-controlled relief valves 65, 66 ; but when the frame tends to tilt, the shock absorber on the side which rises increases the braking effect which counteracts the tendency of the opposite side of the vehicle to drop. In a modification, the resistance of the relief valves is also controlled by the pressure in the connecting pipes 83, 84.
