ABSTRACT:
A hydraulic mount provides active control through the use of a rotary track assembly connecting a primary pumping chamber of the mount to a secondary fluid chamber. With low amplitude vibrations the fluid path remains open, providing low dynamic stiffness. For high amplitude vibrations, the fluid flow path is closed, providing a high level of dynamic stiffness. The rotary track assembly control is continuously variable offering a wide range of active control of hydraulic mount stiffness.
