Yaw Dampers
Yaw dampers are a special feature of rail vehicles
Key Facts
Details
Optional features
However, the high damping forces generated by yaw dampers can impede the vehicle's ability to negotiate switches and tight curves. As a result, wheel-rail forces increase unnecessarily, leading to higher wear as well as increased maintenance and lifecycle costs.
Frequency selective yaw damper (FSC-R)
The FSC-R yaw damper is a passive hydraulic solution that does not require any electronic interface and eases the rotational movement of the bogies in tight curves, thereby reducing wheel-rail forces. Learn more
Electronically controlled yaw damper
Additionally, ZF has developed the electronically controlled yaw damper (with the option of integrated switching point control). It clearly reduces wheel-rail forces by switching a bypass valve on or off.
These options significantly reduce wear-related maintenance costs for both vehicles and track sections.
