A body mount comprises a first support member adapted to engage a body of a vehicle and a second support member adapted to engage a frame of the vehicle. The second support member includes a tubular portion disposed radially inward of a second support surface. A first elastomeric spring interconnects an inner tube and the second support member. The first elastomeric spring is positioned within the tubular portion. A hydraulic damping system is disposed on a side of the second support surface opposite the first support member and includes a housing coupled to the second support member. Second, third and fourth elastomeric springs are positioned within the housing. The second elastomeric spring and the third elastomeric spring are spaced apart by a first track. The third elastomeric spring and the fourth elastomeric spring are spaced apart by a second track.

Hydroelastic body mount

A hydraulic mount includes an inner tubular assembly, first and second elastomeric bodies and a fluid-track. The first and second elastomeric bodies are attached to the inner tubular assembly and cooperate to define a first fluid chamber. The second elastomeric body also defines a second fluid chamber that is in fluid communication with the first fluid chamber via the fluid-track. The fluid-track is attached to the inner tubular assembly partially disposed in the first fluid chamber. The fluid-track includes a central portion, a peripheral portion and a passage. The peripheral portion extends radially outwardly from a periphery of the central portion. The passage provides fluid communication between the first and second fluid chambers. Gaps are positioned between the peripheral portion and a wall of one of the first and second elastomeric bodies. The peripheral portion being configured to contact the wall during loading of the inner tubular assembly to restrict movement of the inner tubular assembly and the fluid-track.
