Abstract
Antivibration isolation device with integrated hydraulic damping, comprising an elastic support consisting of a thick conical elastomer membrane bonded to rigid internal and external framework, and crimped in a rigid casing enclosing a damping liquid acting by the inertia of a very long column, characterized by the fact that an assembly constituted by progressive stops to limit deflections which are rigidly connected to a support washer is enclosed in the chamber thus constituted, and that the space intended for the expansion of the damping liquid is moved to the exterior of the rigid casing, which is the boundary of the elastic support. Application to the suspension of power units of vehicles or truck cabins.
