Abstract
A hydraulic mounting system for mounting a first body relative to a second body, such as a vehicle cab to a chassis, including at least two hydraulic mounts, which are useful for controlling torque between the two bodies. The relative torque-induced displacements of the two bodies are controlled within specific limits in reaction to a pressure applied by a pressure source in response to the actuation of a valve. The valve acts in response to a sensor and the system can include a leveling valve arrangement, or a more sophisticated external electronic control, or respond to a programmed routine. The improved torque-control system behaves as though it is statically stiff for restraining torque and dynamically soft for both translational and rotational isolation purposes. In addition, the system can control torque and damping independent of the direction of application of the torque.
