ABSTRACT:
A resilient mount is disclosed for supporting a cab structure on the chassis of a vehicle. The mount includes a cup-shaped housing which is attached to the chassis such that it can hold a quantity of fluid. A stem which is attached at one end to the cab structure projects through the top of the housing and engages with a fitting which is completely retained in the housing. A pair of flexible members are tightly fitted into the housing above and below the fitting and cooperate to form a fluid cavity therebetween. The top flexible member has an opening therein through which the stem passes while the bottom flexible member contains at least one fluid passage which permits fluid flow therethrough as the size of the passage varies due to the flexing of the bottom flexible member. The mount also includes a valve for regulating fluid flow between the cavity and the fluid passage as the stem moves in and out or laterally relative to the housing. This mount provides both hydraulic and resilient damping of the cab structure relative to the chassis.
