摘要

The suspension support for strengthening a connection and filtering between body shell and the suspension of a vehicle, comprises a main framework (1) and a secondary framework (2) forming lid that surrounds an interior space of the frameworks. The suspension of the vehicle consists of a helicoid spring (4) and a shock absorber. The main framework has a plate shaped bottom pierced by an opening and a parallel peripheral edge. The helicoid spring is useful as a support against a first elastic body (7), which is positioned against an inner side of the peripheral edge. The suspension support for strengthening a connection and filtering between body shell and the suspension of a vehicle, comprises a main framework (1) and a secondary framework (2) forming lid that surrounds an interior space of the frameworks. The suspension of the vehicle consists of a helicoid spring (4) and a shock absorber. The main framework has a plate shaped bottom pierced by an opening and a parallel peripheral edge. The helicoid spring is useful as a support against a first elastic body (7), which is positioned against an inner side of the peripheral edge. A free end of a rod of the shock absorber is placed in an internal space through the opening in a base of the internal space. An axial and radial clearance of the rod is limited by a disc (6) against which the rod is based. The disc is sandwiched between a second and a third elastic ring shaped body, which are inserted into a fourth elastic ring shaped body. The second, third and fourth elastic bodies are made of cellular thermoplastic polyurethane of density (0.4-0.9). An additional elastic body is made of thermoplastic polyurethane of density higher than 1, and is interposed between the disc and the elastic bodies, which forms a U-shaped profile. The two wings of the profile extend respectively on both sides of upper and lower side of the disc. The second, third and fourth elastic ring shaped bodies have closed cells of an average diameter of 100 mu m, density of 107/cm3 and hardness of 75-85 shore A. A peripheral edge of the disc is notched, and comprises a series of openings constituting anchoring channels of polyurethane constitutive of the additional elastic body with respect to the disc. The additional elastic body constitutes an overcasted element on the disc, and the elastic bodies constitute an overcasted element on the additional elastic body.
