  • Method and apparatus for identifying and eliminating vibration symptoms in hydraulic clutch actuators
    Patent number: 6637271
    Abstract: The present invention provides a method and apparatus for identifying and eliminating vibration in a hydraulic clutch actuator. The vibration is identified by using transducers to characterize the vibrational characteristics of a power train of a vehicle. That characterization is used to program a shaker on a test bed to replicate the vibrations on the vehicle in a hydraulic clutch actuator. Different hydraulic dampers may be employed to eliminate the vibration. The preferred apparatus of the present invention includes a two piece hydraulic damper which may be opened as to insert different diaphragms for testing.
