Abstract
A dual-chamber support bed or motor vehicle engine mount with hydraulic cushioning includes a resilient housing part and a support base for use in defining a working chamber and compensating chamber filled with liquid, the housing walls are annular rubber diaphragms with a buckling characteristic that is adjustable to adapt to the operating load. The chambers are connected to one another through a nozzle channel. Means for controlling the buckling characteristics (buckling rigidity) are provided in a wall of the working chamber and in a preferred embodiment include an additional buckling spring that is clamped into the fixed base housing and is adjustable in its buckling behavior from the exterior by a spindle.
Claims10
A dual chamber support bed having a fluid cushioning, especially a motor mount support for motor vehicles, comprising a base housing having a side wall with an opening at one end, a resilient material housing overset opening and secured to said base housing and having spaced apart resilient inner and outer annular walls be positioned over and connected to the open end of said base housing and defining a working chamber between said base housing and said resilient material housing and a compensating chamber between said inner and outer wall, the chambers being filled with a fluid, said inner and outer walls having a buckling characteristic controllable to adapt to variations of supporting load, means defining a nozzle chamber between said base housing and said resilient material housing and inter-connecting said compensating chamber and said working chamber, and a means in said working chamber for controlling the buckling characteristic of said resilient material housing.
