Abstract:
1. A damping strut for a bicycle, having a hydraulic shock absorber comprising: a damping cylinder comprising a damper volume filled with an incompressible damping fluid; a damping piston displaceably arranged in the damping cylinder; a pressure application device configured to detect a displacement of the damping piston with the damping cylinder; at least one disk valve configured such that when the damping piston is displaced, the damper volume changes such that the incompressible damping fluid flows through the at least one disk valve creating a damping force which counteracts the displacement; and a control piston coupled to the disk valve and configured to vary an opening degree of the disk valve, wherein the pressure application device comprises a slider having a slider aperture, wherein the slider is configured to be displaced in correspondence with the detected displacement of the damping piston such that the slider aperture permits selective application, with a compressible control fluid, of a pressure to the control piston depending on the displacement state detected by the pressure application device, such that on detection of a pre-determined displacement state of the damping strut by the pressure application device, the disk valve is pre-tensioned in a closing direction thereof, such that the damping force is increased, and wherein the pressure application device is configured to detect the displacement of the damping piston relative to the damping cylinder via a mechanical coupling between the slider and the damping piston, a hydraulic coupling between the slider and the incompressible damping fluid, or a hydraulic coupling between an electronic displacement sensor and the incompressible damping fluid.
