Abstract
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.
