At least one electronic unit has a printed circuit board which is connected at least indirectly to an actuator housing through a rivet connection.
Claims12
An electromechanical actuator for a motor vehicle, having a torque measuring arrangement which is based on the inverse magnetostrictive principle and has at least one electronic unit, wherein the electronic unit has a printed circuit board which is connected at least indirectly to an actuator housing through a rivet connection, and the rivet connection comprises a number of rivets by means of which the printed circuit board is fixed to a flat carrier element connected to the actuator housing, and a gap is formed between the printed circuit board and the carrier element is a region spaced away from the rivets.
An electromechanical actuator comprising:
- a housing;
- and
- an inverse magnetostrictive torque measuring arrangement having a printed circuit board which is connected to the housing via a rivet connection;
- and
- the rivet connection comprises a number of rivets by means of which the printed circuit board is fixed to a flat carrier element connected to the housing;
- and
- a gap is formed between the printed circuit board and the carrier element.
A roll stabilizer comprising:
- an actuator housing;
- a carrier connected to the actuator housing;
- and
- an inverse magnetostrictive torque measuring arrangement having a printed circuit board which is connected to the carrier via a rivet connection;
- and
- the actuator housing includes a central housing region and a tapered housing region;
- and
- the printed circuit board is arranged in the tapered housing region.
