Abstract

A drive element ( 1 ) of a camshaft adjuster, the drive element ( 1 ) being pot-shaped and having a center receiving portion ( 3 ) for an output element that can be connected to a camshaft for conjoint rotation therewith, the drive element ( 1 ) including a locking gate ( 4 ) and the locking gate ( 4 ) protruding beyond the base ( 6 ) of the pot-shaped drive element ( 1 ) in the axial direction ( 5 ) is provided.

First claim

1 - 10 . (canceled)

11 . A driving element of a camshaft adjuster, the driving element being pot-shaped and comprising:
a central accommodation for an output element rotatably fixedly connectable to a camshaft; a base; and a locking link protruding in an axial direction beyond the base.

12 . The driving element as recited in claim 11 wherein the locking link is pot-shaped and formed as a single part by the driving element.

13 . The driving element as recited in claim 12 wherein the locking link has been subjected to a heat treatment different from that of a remainder of the driving element.

14 . The driving element as recited in claim 11 wherein the locking link includes an insert capable of being brought into contact with a locking piston.

15 . The driving element as recited in claim 11 wherein the locking link includes a ring capable of being brought into contact with a locking piston.

16 . The driving element as recited in claim 15 wherein the ring has a protruding collar fixing the ring in the axial direction.

17 . The driving element as recited in claim 16 wherein the collar is situated on an inner side of the pot-shaped driving element.

18 . The driving element as recited in claim 15 wherein the ring has an anchoring structure at an outer circumference.

19 . The driving element as recited in claim 11 wherein the locking link includes a pot-shaped insert accommodatable in an opening of the driving element and capable of being brought into contact with a locking piston.

20 . The driving element as recited in claim 19 wherein the pot-shaped insert has a protruding collar fixing the pot-shaped insert in the axial direction.

21 . The driving element as recited in claim 20 wherein the collar is situated on an inner side of the pot-shaped driving element.

22 . The driving element as recited in claim 19 wherein the pot-shaped insert has an anchoring structure at an outer circumference.

23 . A camshaft adjuster comprising the driving element as recited in claim 11 .
