Abstract

See full text

A vehicle wheel suspension has a hydraulic adjustment system for the base of a support spring provided between a wheel-guide component and the vehicle structure. The suspension includes a piston pump which is driven via a relative movement of the vehicle structure in relation to a wheel-guiding component and intended for conveying hydraulic medium through a return valve into a hydraulic chamber provided at the spring base, as well as a pressurized compensation volume for providing hydraulic medium. Preferably, the piston pump has a pump cylinder and a pump piston guided such that it can move relative to the former and a return channel connected to the hydraulic chamber feeds into the pump cylinder in such a way that the feed opening is blocked or released by the pump piston in a position-dependent manner, wherein hydraulic medium can flow via the released feed opening, out of the hydraulic chamber, through the pump cylinder and into the compensation volume.
