1. A vehicle wheel suspension, comprising:

  • a hydraulic vibration damper connected in parallel to a suspension spring proportionally supporting the vehicle body, the vibration damper including;

    a dampening housing;

    a rebound spring that first becomes effective in an event of larger spring deflection distances,a spring support piston provided in the damper housing and being displaceable by fluid externally supplied with pressure by a pump,a support point of the rebound spring being displaceable in relation to the damper housing of the vibration damper by way of the spring support piston, wherein;

    the pump is connected to a pressure accumulator for said fluid and delivers fluid out of said pressure accumulator into the damper housing or out of the damper housing back into the pressure accumulator, andan absolute value of the spring constant of the pressure accumulator is at least on an order of magnitude of the spring constant of the associated suspension spring or, in the case of multiple suspension springs associated with one pressure accumulator, the spring constants of the multiple suspension springs, or is greater.
