Abstract
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.
Claims18
An automotive transmission mount, comprising:
- a top bracket configured to be attachable to a transmission housing;
- a bottom bracket configured to be attachable to a vehicle frame and being interlocked with the top bracket to prevent separation of the bottom bracket from the top bracket;
- a resilient material disposed between the top bracket and the bottom bracket;
- and
- a lateral relief hole extending through the resilient material and being oriented parallel to the top bracket, the lateral relief hole being adapted to deform during compression of the resilient material as a result of relative movement of the top bracket toward the bottom bracket such that shearing of the resilient material is prevented.
An automotive transmission mount, comprising:
- a top bracket configured to be attachable to a tail shaft of a transmission housing, the top bracket being T-shaped and comprising a top plate portion and a vertical plate portion extending laterally outwardly from the top plate portion, the vertical plate portion includes a circular opening formed therewithin;
- a bottom bracket configured to be attachable to a cross member of a vehicle frame, the bottom bracket being U-shaped and comprising a horizontal web and a pair of spaced vertical webs extending laterally outwardly from the horizontal web and having a cylindrical locking pin extending between the pair of vertical webs, the locking pin being disposed in spaced parallel relation to the horizontal web and passing through a center of the opening to interlock the top bracket to the bottom bracket;
- a polyurethane material overmolding the top and bottom brackets;
- and
- a lateral relief hole extending through the polyurethane material and being oriented parallel to the top bracket, the lateral relief hole being adapted to deform during compression of the polyurethane material as a result of relative movement of the top bracket toward the bottom bracket such that shearing of the polyurethane material is prevented.
