Abstract:
A vehicle wheel suspension is provided having a hydraulic vibration damper, which is connected in parallel to a suspension spring which proportionally supports the vehicle body. A rebound spring is provided, which preferably and typically becomes effective in the event of larger spring deflection distances. The support point of the rebound spring is displaceable in relation to the damper housing by way of a spring support piston, which is provided therein and is displaceable by fluid externally supplied with pressure via pump. In this case, the pump is connected to a pressure accumulator for the fluid and delivers fluid out of the pressure accumulator into the damper housing or out of the damper housing back into the pressure accumulator. The absolute value of the spring constant of the pressure accumulator is at least in the order of magnitude of the spring constant of the associated suspension spring or springs, or is greater.
