Abstract

The invention relates to a differential spring damping for use in the spring suspension of a motor sledge. Bearing points of rocker brackets 1,2 in a slide rail 7,8, a frame 9 and a hydraulic actuating member 3 form, in relation to one another, such points that, when spring load is supplied to the slide rail 7,8, it is transmitted as torque to the driving bracket 1 or 2. The torque is transmitted as thrust, through the agency of the actuating member 3, to the opposite rocker bracket 1 or 2, which is driven and the motion of which is greater, so that it receives the differential spring damping. The hydraulic pressure is produced most expediently with the motor in a pressure-former unit 4 and is set to an appropriate value by way of a regulator 5 and transmitted most expediently to the actuating member 3 via a line 6. By adjusting the length of the piston rod of the hydraulic actuating member 3, the angle of the rocker brackets 1,2 is able to be changed, whereby the belt 10 is pressurized in the desired manner through the agency of the slide rails 7,8. If the spring load is too high, the regulator 5 reduces the liquid pressure, whereupon the piston rod of the actuating member 3 slides in the cylinder and returns to a chosen length once the spring load force drops to normal. <IMAGE>
