Hybrid type vibration isolation apparatus

Abstract

A hybrid type vibration isolation mounting apparatus for supporting a first member at a second member, and including a passive vibration absorbing device, such as a typical rubberized engine mount, located between the first and second members, and an active vibration actuator for applying counter vibration isolation forces in parallel in response to the detected relative vibration of the first and second members, wherein the actuator is located on a support mount frame attached to the second member. The support mount frame provides a structure for the actuator force application, with continuous transfer of static loads between the first and second member being provided by the passive device. In its preferred embodiment, the apparatus is utilized in conjunction with vehicle engine mounts wherein the first member comprises the engine and the second member comprises the vehicle frame.
