Abstract

The invention relates to an apparatus for the compensation of tolerances between components to be screwed to one another, comprising a hollow-cylindrical base element and a hollow-cylindrical compensation element which is in threaded engagement with the base element and which can be moved from a starting position into a compensation position by rotation relative to the base element. The apparatus is characterized in that a fixing means is provided by which the compensation element can be fixed in the compensation position relative to the base element.

First claim

The invention claimed is:

1. An apparatus ( 10 ) for compensating tolerances between components to be screwed to one another, comprising
a hollow-cylindrical base element ( 18 ); and
a hollow-cylindrical compensation element ( 22 ), said hollow-cylindrical compensation element being in threaded engagement with the base element ( 18 ) and being able to be moved from a starting position into a compensation position by rotation relative to the base element ( 18 ),
the apparatus further comprising two fixing wedges ( 40 , 58 ) by means of which the compensation element ( 22 ) can be fixed relative to the base element ( 18 ) in the compensation position,
the two fixing wedges being arranged in parallel to one another such that they are in clamping engagement with the compensation element ( 22 ) in the fixing position on oppositely disposed sides of the compensation element ( 22 ), wherein the fixing wedges ( 40 ) each have a substantially rectangular cross-section and taper toward a front end, whereby a wedge-shaped section is formed,
a fixing housing attached to the base element ( 18 ), with the fixing wedges ( 40 ) being arranged displaceable in the fixing housing ( 34 ).

2. The apparatus ( 10 ) in accordance with claim 1 , wherein the fixing wedges ( 40 , 58 ) are configured to secure the compensation element ( 22 ) against a rotation relative to the base element ( 18 ).

3. The apparatus ( 10 ) in accordance with claim 1 , wherein the fixing wedges ( 40 , 58 ) fix the compensation element ( 22 ) relative to the base element ( 18 ) by means of at least one of a material continuity and friction locking.

4. The apparatus ( 10 ) in accordance with claim 1 , wherein the fixing wedges ( 40 , 58 ) can be moved out of a position of rest into a fixing position.

5. The apparatus ( 10 ) in accordance with claim 4 , further comprising securing means ( 52 ) for securing the fixing wedges ( 40 ) in the fixing position.

6. The apparatus ( 10 ) in accordance with claim 1 , wherein the fixing wedges ( 40 ) are connected to one another by a connection element ( 54 ).

7. The apparatus ( 10 ) in accordance with claim 6 , wherein the connection element is formed in one piece with the fixing wedges ( 40 ).

8. The apparatus ( 10 ) in accordance with claim 1 , wherein the fixing wedges ( 40 ) are connected to one another by a connection element ( 54 ), said connection element extending at a right angle to the fixing wedges ( 40 ).

9. The apparatus ( 10 ) in accordance with claim 8 , wherein the connection element is formed in one piece with the fixing wedges ( 40 ).

10. The apparatus ( 10 ) in accordance with claim 1 , wherein the fixing wedges ( 40 , 58 ) each have a toothed arrangement ( 52 ) and the fixing housing ( 34 ) has a latch projection which engages into the toothed arrangement for securing the fixing wedges ( 40 , 58 ) in the fixing position.
