Abstract

A camshaft adjuster ( 1 ) is provided that has a drive element ( 2 ), a driven element ( 3 ), and at least one side cover ( 5 ). The side cover ( 5 ) has, for supporting a spring ( 4 ), several screw bosses ( 6 ) that are penetrated by screws ( 7 ) that are provided for a rotationally locked connection between the side cover ( 5 ) and the drive element ( 2 ) or the driven element ( 3 ).

Claims (17)

1. A camshaft adjuster comprising:

a drive element, a driven element, a spring, and a side cover,

the drive element, the driven element, the spring, and the side cover are arranged coaxial to a rotational axis of the camshaft adjuster,

the drive element and the driven element are arranged to rotate relative to each other,

the spring tensions the drive element and the driven element in a peripheral direction,

the side cover is locked in rotation with the drive element or the driven element by a screw that includes a radially enlarged screw head,

the side cover has a screw boss that is penetrated by the screw,

the screw boss is formed as a support that supports the spring, and the screw head provides an axial stop for the spring.

2. The camshaft adjuster according to claim 1 , wherein the screw boss is arranged parallel to and at a radial spacing to the rotational axis of the camshaft adjuster.

3. The camshaft adjuster according to claim 1 , wherein the screw boss is formed integrally with the side cover.

4. The camshaft adjuster according to claim 1 , wherein the screw boss is penetrated by a screw shaft of the screw.

5. The camshaft adjuster according to claim 1 , wherein the screw boss is formed as a socket and is connected to the side cover with a positive fit, non-positive fit, or material fit connection.

6. The camshaft adjuster according to claim 5 , wherein the socket penetrates the side cover.

7. The camshaft adjuster according to claim 5 , wherein the socket penetrates both the side cover and also the drive element or the driven element with which the side cover is locked in rotation.

8. The camshaft adjuster according to claim 7 , wherein the rotationally locked connection between the side cover and the drive element or the driven element is formed by the socket.

9. The camshaft adjuster according to claim 1 , wherein a rotationally locked connection between the side cover and the drive element or the driven element is formed by the screw boss, which penetrates the drive element or the driven element.

10. The camshaft adjuster according to claim 1 , wherein the screw boss is formed as a contact for the screw head, and a diameter of the screw boss is smaller than a diameter of an enveloping cylinder surface of the screw head.
