Abstract
A top hydro-pneumatic suspension mount is embodied in a single path preloaded shear compression arrangement achieved by positioning a rate plate between the upper jounce plate and the molding assembly thereby providing a digressive rate performance concurrently providing stiff performance for supporting the vehicle and resilient performance for isolating vertical road input loads.
Claims5
A mount for attaching a suspension damper to a body comprising:
- an upper jounce plate;
- a molding assembly including an inner cup and an outer cup radially outside the inner cup, said cups connected together by a resilient cushion;
- and
- a rate plate interposed between the upper jounce plate and the molding assembly such that a load is established in the resilient cushion due to a displacement of the outer cup caused by the interpositioning of the rate plate.
