Abstract

A support arrangement for an actuator of a cam phaser, the support arrangement including an actuator module including an actuator; and a support element configured to support the actuator module on a camshaft, wherein the actuator module is connected to the support element by an electrical contact arrangement configured to actuate the actuator, and wherein the electrical contact arrangement includes an elastic clamping element.

First claim

What is claimed is:

1. A support arrangement for an actuator of a cam phaser, the support arrangement comprising:
an actuator module including an actuator; and
a support element configured to support the actuator module on a camshaft,
wherein the actuator module is connected to the support element by an electrical contact arrangement configured to actuate the actuator,
wherein the electrical contact arrangement includes an elastic clamping element,
wherein the elastic clamping element includes a first clamping arm configured to clamp and fix an actuator contact,
wherein the elastic clamping element includes a second clamping arm configured to clamp and fix the actuator contact,
wherein the second clamping arm is arranged opposite to the first clamping arm,
wherein the clamping element includes a third clamping arm configured to clamp and fix the actuator contact, and
wherein the first clamping arm, the second clamping arm and the third clamping arm together form an M-shaped receiver for the actuator contact.

2. The support arrangement according to claim 1 , wherein the Elastic clamping element is arranged at the support element.

3. The support arrangement according to claim 1 , wherein the elastic clamping element includes a first clamping device and a second clamping device.

4. The support arrangement according to claim 3 , wherein the first clamping device and the second clamping device are arranged parallel to each other.

5. The support arrangement according to claim 1 , wherein the first clamping arm, the second clamping arm and a third clamping arm is arranged at an angle between 0° and 80° or between 10° and 60° relative to a longitudinal axis of the elastic clamping element.

6. The support arrangement according to claim 1 , wherein the first clamping arm, the second clamping arm and a third clamping arm is bent in a direction facing away from the actuator module in a state in which the actuator module is supported at the support element.

7. The support arrangement according to claim 1 , wherein the clamping element is arranged in at least one sealed pocket of the support element.

8. The support arrangement according to claim 1 , wherein the support element includes a surrounding plastic molding.

9. The support arrangement according to claim 1 , wherein the support element is welded to the actuator module.

10. The support arrangement according to claim 1 ,
wherein the actuator module includes at least one outward protruding pin which is introducible into a corresponding depression of the support element.

11. The support arrangement according to claim 10 , wherein the pin is configured to be welded to the support element.
