Abstract:
1. A hydraulic mount comprising: a resilient hollow body defining a primary fluid chamber and a secondary fluid chamber; a rotary track assembly separating the primary and secondary fluid chambers; a rotary actuator operably connected to the rotary track assembly; a controller operably connected to the rotary actuator; and at least one sensor operably connected to the controller for sensing vibrational amplitude, wherein the rotary track assembly comprises: an orifice plate including a plurality of openings; a containment plate securely attached to the orifice plate, the containment plate including a wall portion, the wall portion including a plurality of tab portions defining a plurality of fluid chambers; and a rotary track disposed between and rotatably coupled to the orifice plate and the containment plate, the rotary track including a wall portion and a base portion, the rotary track wall portion including a first plurality of rotary track openings and the rotary track base portion including a second plurality of rotary track openings; and wherein the controller receives a sensed vibrational amplitude from the at least one sensor and sends a signal to the rotary actuator to rotate The rotary track assembly based on the sensed vibrational amplitude.
