专利汇可以提供Shock absorber means, especially for a vehicle steering column专利检索，专利查询，专利分析的服务。并且To permit axial thrust of the steering column of an automobile from the shock due to an accident, the inner end of the column is constituted by two omega-shaped parts, connected to the steering mechanism through a damping device comprising two semi-circular rubber masses. The masses are precompressed between a continuous outer ring and a central sleeve constituted by two omega-shaped parts clamping between themselves the first said omega-shaped parts. Bulges are provided on the latter to separate the parts of the sleeve and to rub against them after the shock.，下面是Shock absorber means, especially for a vehicle steering column专利的具体信息内容。

权利要求

1. Damping device in combination with and interposed between at least two parts, especially between a steering column of an automobile vehicle and a part connected to the steering mechanism, said device comprising an elastic coupling including elastic masses, first means clamping said elastic masses peripherally and connected rigidly to one said part, and second means disposed in internal contact with said elastic masses and connected rigidly to the other said part, so as to permit the damping of shocks by said elastic masses on relative axial displacement of said two parts, said displacement being effected first against an initial elastic deformation of said elastic masses working especially in shear, said other part and said second means being arranged for relative axial frictional displacement only after said initial deformation, between the surfaces subjected to the pressure of said masses.

2. The combination according to claim 1, wherein said means comprise two armatures inside one another, one armature being connected to the steering mechanism, the other armature to the steering column, with the elastic masses between said two armatures and arranged to provide friction between the inner armature and the steering column beyond said initial deformation.

3. The combination according to claim 2, wherein the inner armature is constituted by two cylindrical parts with lateral rims, and the steering column itself comprises two half-parts arranged in similar manner, the introduction of the column into the inner armature causing precompression of the elastic masses.

4. The combination according to claim 3, wherein the ouTer rims of the two half-cylinders of the steering column comprise bulges which position the said column with respect to the coupling, and which, in addition, during the relative axial displacement of the column with respect to the coupling, have the effect of further separating the two half-parts of the inner armature of the coupling and of increasing the compression of the masses, whilst causing thereby a damping friction.

5. The combination according to claim 3, wherein on the edges of the two half-parts of the steering column, are provided bulges enabling the two half-parts of the inner armature to be kept separated in the course of damping friction.

6. The combination according to claim 5, wherein certain of said bulges have an enlarged shape to enable the contact surfaces to be increased.

7. The combination according to claim 1, wherein to facilitate the precompression of the rubber, cavities are provided in the elastic masses.

8. The combination according to claim 7, wherein the inner armature is constituted by two cylindrical parts with lateral rims, and the steering column itself comprises two half-parts arranged in similar manner, the introduction of the column into the inner armature causing precompression of the elastic masses.

9. The combination according to claim 8, wherein on the edges of the two half-parts of the steering column, are provided bulges enabling the two half-parts of the inner armature to be kept separated in the course of damping friction.
