  • Hydraulic torque restraint system
    Patent number: 5918833
    Abstract: A suspension system attaches an engine to a vehicle frame and includes resilient mounts that are relatively soft with respect to vibrational movement of the engine along horizontal and vertical axes. This soft connection reduces transmission of vibration from the engine to the vehicle frame. The suspension system also provides a pair of hydraulic restrainers mounted on opposite sides of the engine which react equally, but in opposite directions to loads. The hydraulic restrainers are relatively stiff with respect to torsion that results from engine rotation, yet is soft with respect to translational movement of the engine.
