Damping valve arrangement with a frequency-dependent damping force characteristic

摘要

A frequency-selective damping valve arrangement 2 of a motor vehicle vibration damper 1 is specified, comprising: a valve body 3 with at least one fluid channel 4 which projects axially through the valve body 3 and through which a damping fluid flows due to an excitation caused by a telescopic compression or a telescopic expansion of the motor vehicle vibration damper 1 - wherein the fluid channel 4 is axially covered by at least one resilient valve disc 5, and - a support arrangement 6 arranged coaxially to the valve disc 5 with a support section 7 which comes to rest axially on the valve disc 5 and a supporting force F1 directed towards the valve body 3 exerts on the valve disc 5, the radial extent D1 of the support section 7 being smaller than the radial extent D2 of the valve disc 5. The damping valve arrangement 2 according to the invention is characterized in that the support arrangement 6 is designed such that the radial first line eckung D1 whose support section 7 can be changed as a function of the excitation frequency of the motor vehicle vibration damper 1.
