Hydraulic damper for railway applications
CVD Series
ITT Enidine Inc.
The electrically controlled yaw damper can be switched off and on, resulting in a smooth ride at low speeds on curvy tracks (valve open) and safe and steady ride at high speeds (valve closed).
It relieves the engineers from accepting a compromise between comfort and safety. Moreover, the system provides inherent safe operation, even if the external power supply is down.
Continuous variable
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, KONI has developed a revolutionary system, which exactly does that!
