Abstract

An actuator assembly for a vehicle brake is described, with a brake calliper in which a space is formed for a brake disc, and an actuating slide for a brake pad. The actuating slide can be moved optionally between a retracted position and an extended position. In the brake calliper, adjoining the space, a sleeve-like portion is formed with a running face for the actuating slide. The actuating slide is received in the sleeve-like portion and is guided linearly on the running face.

First claim

1 . An actuator assembly for a vehicle brake, comprising:
a brake calliper in which a space is formed for a brake disc, an actuating slide for a brake pad, wherein the actuating slide can be moved optionally between a retracted position and an extended position, and wherein in the brake calliper, adjoining the space, a sleeve-like portion is formed with a running face for the actuating slide, wherein the actuating slide is received in the sleeve-like portion and is guided linearly on the running face.

2 . The actuator assembly according to claim 1 , wherein the actuator assembly comprises an electric motor which is coupled for drive purposes to the actuating slide via a gear unit and a spindle drive, in order to move the actuating slide between the retracted position and the extended position.

3 . The actuator assembly according to claim 1 , wherein the sleeve-like portion is open towards the space.

4 . The actuator assembly according to claim 1 , wherein an opening is present in the brake calliper in a region of the sleeve-like portion, and a rotational locking element protrudes through the opening and engages in an axially running groove on the actuating slide.

5 . The actuator assembly according to claim 1 , wherein on an end facing away from the space, the sleeve-like portion has a wall which runs transversely to a movement direction of the actuating slide, wherein a spindle drive rests axially on the wall.

6 . The actuator assembly according to claim 5 wherein an opening is present in the wall, wherein a shaft of the spindle drive extends through the opening and the shaft is coupled to the gear unit outside the sleeve-like portion.

7 . The actuator assembly according to claim 1 , wherein a rotational locking geometry is formed on an outer wall of the brake calliper in a region of the sleeve-like portion for a form-fit connection of the brake calliper to a frame part of a carrier assembly.

8 . The actuator assembly according to claim 7 , wherein the rotational locking geometry is a splined shaft geometry.

9 . The actuator assembly according to claim 1 , wherein a recess for a seal is provided on an inside of the brake calliper at a transition from the space to the sleeve-like portion.

10 . The actuator assembly according to claim 2 wherein an opening is present in the wall, wherein a shaft of the spindle drive extends through the opening and the shaft is coupled to the gear unit outside the sleeve-like portion.

11 . The actuator assembly according to claim 3 , wherein an opening is present in the brake calliper in a region of the sleeve-like portion, and a rotational locking element protrudes through the opening and engages in an axially running groove on the actuating slide.

12 . The actuator assembly according to claim 4 , on an end facing away from the space, the sleeve-like portion has a wall which runs transversely to a movement direction of the actuating slide, wherein a spindle drive rests axially on the wall.

13 . The actuator assembly according to claim 6 , wherein a rotational locking geometry is formed on an outer wall of the brake calliper in a region of the sleeve-like portion for a form-fit connection of the brake calliper to a frame part of a carrier assembly.

14 . The actuator assembly according to claim 12 , wherein a recess for a seal is provided on an inside of the brake calliper at a transition from the space to the sleeve-like portion.
