Abstract:
A vehicle powertrain mount includes a housing and first and second compliant members coupled to and cooperating with the housing. An inertia track assembly cooperates with the first compliant member to form a first fluid chamber and second fluid chamber with the second compliant member. The inertia track assembly includes at least first and second channels for conducting fluid between the first fluid chamber and the second fluid chamber. An air chamber in the inertia track assembly cooperates with a decoupler disposed therein. A switching apparatus is operatively connected to the housing and selectively positionable relative to the inertia track assembly. The switching apparatus includes an actuator with a plunger having a first portion positionable relative to the second channel and a second portion synchronously positionable relative to the air chamber.
