Abstract
A suspension strut for a wheel suspension of a vehicle may have a vibration damper, a supporting spring that partially surrounds an outer tube of the vibration damper and is supported by a spring collar, and a lifting device for height adjustment of the vehicle. The lifting device may comprise a hollow piston and a cylinder that are arranged concentrically around the outer tube. The hollow piston may be guided axially between the outer tube and the cylinder and is connected to the spring collar to adjust a base point of the supporting spring. The hollow piston may comprise a stripping and sealing element that lies against the vibration damper.
