Control grooves in the cylinder tube, which create a hydraulic bypass, are used to implement stroke-dependent damping. The hydraulic bypass works on the piston valve. It is mechanically formed in the cylinder tube of the shock absorber.
The piston travels over the control groove depending on the shock absorber position and stroke. When oil flows over the groove, hydraulic resistance is reduced and therefore the damping force as well. The damping forces are significantly higher outside the grooves – for even more driving safety.
Careful design of the transition profile between the groove and the smooth part of the cylinder prevents abrupt changes in vehicle damping.
- Enhanced comfort
- Integration into standard shock absorbers possible
- Can replace existing shock absorbers
- No control elements needed
