Abstract
A tunable hydraulic bushing mounts a steering gear to a vehicle frame member. The bushing is filled with a fluid and includes an inertia track and a pressure valve separating first and second fluid chambers or cavities. The inertia track provides uninterrupted fluid communication between the first cavity and the second cavity. The pressure valve is movable between an open position, which allows fluid communication though the pressure valve between the first cavity and the second cavity, and a closed position, which blocks fluid communication though the pressure valve between the first cavity and the second cavity. The pressure valve may be configured to be closed during loads induced by smooth road shake and open during loads greater than smooth road shake.
