With a conventional damper, the damping characteristic of a secondary horizontal railway shock absorber is always a compromise between the ability of this damper to isolate long wave vibrations, while at the same time filtering the high frequency shocks working on the passenger compartment.
In other words; a compromise between stability and comfort. To damp this complete spectrum of vibrations, ideally the damper forces should be continuously adjusted to the exact level of damping required.
With our patented Continuously Variable Damping (CVD) system, we have developed a revolutionary system, which does exactly that.
