Abstract

A bearing arrangement for connecting two components including a bearing bushing having an inner sleeve and an elastic element surrounding the inner sleeve. Two connection portions are arranged axially on both sides of the inner sleeve wherein a connector having a shaft portion extending through the inner sleeve applies a clamp force compressing the connection portions axially against the inner sleeve. The inner sleeve is deformed by the clamp force of the connector in such a manner that at least one contact portion of the inner sleeve presses radially to the inside and against the shaft portion.

First claim

What is claimed is:

1. A bearing arrangement comprising:
a bearing bushing having an inner sleeve and an elastic element surrounding said inner sleeve;
said inner sleeve having an inner recess and a collar formed on at least one end region of said inner sleeve; and
a connector having a shaft portion extending through the inner recess of said inner sleeve and spaced from the inner recess of said inner sleeve wherein a clamp force of the connector acts on said collar and presses a contact portion of said inner sleeve against said shaft portion; and
an axial projection extending from the end region of said inner sleeve, said axial projection closer to the inner recess in said inner sleeve than to an outer surface of said inner sleeve adjacent to an elastic element.

2. The bearing arrangement of claim 1 including a connection portion arranged in a force-transmitting manner between the connector and the inner sleeve.

3. The bearing arrangement of claim 1 including a radially outwardly directed collar formed on at least one end region of the inner sleeve.

4. The bearing arrangement of claim 1 including the contact portion formed in an end region of the inner sleeve.

5. The bearing arrangement of claim 1 including the inner sleeve having first and second end regions and a contact portion formed in both of the first and second end regions of the inner sleeve.

6. The bearing arrangement of claim 1 including a radially inwardly extending collar formed in an end region of said inner sleeve, said collar including said contact portion.

7. The bearing arrangement of claim 1 including an outer sleeve surrounding the elastic element wherein the inner sleeve has an axial length greater than an axial length of the outer sleeve.

8. A bearing arrangement comprising:
a bearing bushing having an inner sleeve and an elastic element surrounding said inner sleeve;
said inner sleeve having a radially outwardly directed collar formed on at least one end region of said inner sleeve;
a connector having a shaft portion extending through said inner sleeve wherein a clamp force of the connector acts on said collar and presses a contact portion of said inner sleeve against said shaft portion; and
an axially extending recess formed in said contact portion.

9. A bearing arrangement comprising:
a bearing bushing having an inner sleeve and an elastic element surrounding said inner sleeve;
said inner sleeve having a radially outwardly directed collar formed on at least one end region of said inner sleeve;
a connector having a shaft portion extending through said inner sleeve wherein a clamp force of the connector acts on said collar and presses a contact portion of said inner sleeve against said shaft portion; and
a radially inwardly extending collar formed in an end region of said inner sleeve, said collar including said contact portion.

10. A bearing arrangement comprising:
a bearing bushing having an inner sleeve and an elastic element surrounding said inner sleeve;
said inner sleeve having a first contact portion formed in a first end region of said inner sleeve and a second contact portion formed in a second end region of said inner sleeve;
a connector having a shaft portion extending through said inner sleeve wherein a clamp force of the connector presses said first and second contact portions of said inner sleeve against said shaft portion;
first and second radially inwardly directed collars, said first and second radially inwardly directed collars formed at respective first and second end regions of the inner sleeve; and
said first radially inwardly directed collar including said first contact portion and second radially inwardly directed collar including said second contact portion.

11. The bearing arrangement of claim 10 including an axial projection formed at an axial end of each of said first and second radially inwardly directed collars.

12. The bearing arrangement of claim 10 including an axially extending recess formed in each of said first and second contact portions.

13. A bearing arrangement comprising:
a bearing bushing having an inner sleeve and an elastic element surrounding said inner sleeve;
a connector having a shaft portion extending through said inner sleeve;
said inner sleeve having an end region and a contact portion formed in the end region of said inner sleeve;
said inner sleeve having a central region, said central region spaced from said shaft portion; and
wherein a clamp force of the connector presses said contact portion of said inner sleeve against said shaft portion while said central region remains spaced from said shaft portion.

14. The bearing arrangement of claim 13 including said inner sleeve having opposing end regions;
said contact portion includes each of the opposed end regions of the inner sleeve having a contact portion; and
said clamp force of the connector pressing both of the contact portion of each end region of the inner sleeve against the shaft portion.

15. The bearing arrangement of claim 13 including a radially inwardly extending collar formed in an end region of said inner sleeve, said collar including said contact portion.

16. The bearing arrangement of claim 13 including an axial projection extending from the end region of said inner sleeve, said axial projection spaced from an outer surface of the inner sleeve.
