Abstract
A mounting system incorporating a hydraulic torque strut provides torsional damping and noise suppression of vehicle engine vibrations. The strut includes a first mount connected to the engine and a second mount connected to the frame of the vehicle. A rod rigidly connects the two mounts together. One or both of the mounts is a hydraulic mount. The hydraulic mount includes an elastomeric body that is connected to a mounting member and forms a cavity filled with damping liquid. An integral partition divides the cavity into two chambers. An orifice track in the partition provides fluid communication between the two chambers. Passage of damping liquid through the orifice track provides damping action. Further, in order to provide decoupling for vibration isolation and noise suppression, a spool-type decoupler is mounted for reciprocal movement in the opening in the partition.
