US Patent 7784763 Transmission mount

An automotive transmission mount comprises a top bracket, a bottom bracket and a polyurethane material overmolding to top and bottom brackets. The top bracket is attachable to a tail shaft of a transmission housing. The bottom bracket is attachable to a cross member of a vehicle frame. The polyurethane material includes a lateral relief hole extending therethrough and being oriented parallel to the top bracket. The lateral relief hole is adapted to deform during compression of the resilient material as a result of relative movement of the top bracket toward the bottom bracket to prevent shearing of the polyurethane. The top bracket and bottom brackets are also interlocked to one another to prevent their separation.
