Abstract
A hydraulic body mount includes a first support member that defines a first support surface that is adapted to engage the body of a vehicle and a second support member that defines a second support surface that is adapted to engage the frame of the vehicle. The hydraulic body mount includes a hydraulic damping system disposed between the first support surface and the second support surface and a travel-limiting cup disposed outside of the region between the first support surface and the second support surface. The travel-limiting cup includes an elastomeric limiting member adapted to limit the travel of the first support surface relative to the second support surface.
Claims20
A hydraulic body mount for connection between a body and a frame of a vehicle, comprising:
- a first support member defining a first support surface adapted to engage the body of the vehicle;
- an inner tube including a proximal end and a terminal end, the inner tube connected to the first support member at the proximal end and extending axially away from the first support surface along a central axis;
- a second support member defining a second support surface adapted to engage the frame of the vehicle, the second support member including a cup portion disposed radially inward of the second support surface and extending axially away from both the first support surface and the second support surface toward the terminal end of the inner tube;
- a hydraulic damping system disposed between the first support surface and the second support surface;
- and
- a travel-limiting cup directly joined to the cup portion of the second support member, the travel-limiting cup including an elastomeric limiting member connected to the terminal end of the inner tube.

- a first support member defining a first support surface adapted to engage the body of the vehicle;
- a cover member including a rigid canopy, an inner tube and a first elastomeric spring, the inner tube connected to the first support member and extending axially away from the first support surface along a central axis and the first elastomeric spring connecting the inner tube to the rigid canopy;
- a connector member including a connector plate, a second elastomeric spring and a channel support, the channel support joined to the connector plate by the second elastomeric spring and the connector plate including a central aperture receiving the inner tube;
- a second support member including a sleeve, a third elastomeric spring and a rigid base, the rigid base connected to the sleeve by the third elastomeric spring and defining a second support surface adapted to engage the frame of the vehicle;
- and
- a travel-limiting cup directly joined to the second support member at an axial distance away from the second support surface, the travel-limiting cup disposed on a side of the second support member away from the first support surface and including an elastomeric limiting member and a washer, the elastomeric limiting member connected to the washer,
- wherein the channel support is connected to the second support member to define a channel, the first elastomeric spring and the second elastomeric spring define a first chamber, and the second elastomeric spring and the third elastomeric spring define a second chamber, the first chamber and the second chamber being fluidly connected via an aperture in the channel support to permit fluid to travel in the channel between the first chamber and the second chamber.
