Abstract

An exemplary brake booster device includes a brake booster mounted on a vehicle component, and an actuator lever that, in response to a force applied to the actuator by a gearbox housing, pivots to move the brake booster upward. An exemplary method includes pivoting an actuator lever about a pivot axis under a force effect in an X direction resulting from a gearbox housing, and, during the pivoting, using the actuator lever apply a force in a Z direction to a module mounted on a bulkhead to alter a position of the module mounted on the bulkhead.

First claim

What is claimed is:

1. A brake booster device, comprising:
a brake booster mounted on a vehicle component via at least one fastening point; and
an actuator lever which is designed to pivot about a pivot axis extending in the Y direction under a force effect in the X direction resulting from a gearbox housing, whereby the actuator lever applies a force to the brake booster in the Z direction, as a result of which the position of the brake booster is alterable, wherein the actuator lever has an angular arm which is supported below the brake booster on the vehicle component via at least one pivot bearing, wherein a convex side of the actuator lever faces away from the brake booster such that the actuator lever is configured to apply an upward force to the brake booster in the Z direction during a pivotal movement.

2. The brake booster device of claim 1 , wherein the brake booster is rotated about a rotary axis in the Y direction as a result of the force of the actuator lever.

3. The brake booster device of claim 2 , wherein the rotary axis is located at a fastening point of the brake booster on the vehicle component.

4. The brake booster device of claim 1 , wherein the brake booster is displaced in the Z direction as a result of the force of the actuator lever.

5. The brake booster device of claim 1 , wherein the brake booster is displaced along a surface of the vehicle component on which the at least one fastening point is located.

6. The brake booster device of claim 1 , wherein the angular arm is supported on a vehicle component via a fork having two fork bearings.

7. The brake booster device of claim 1 , wherein the at least one fastening point is formed by an elongated hole having two lateral narrowed portions through which the elongated hole is divided into two mutually adjacent hole regions, wherein the longitudinal extent of the elongated hole extends in the Z direction and, upon the application of a force to the brake booster in the Z direction, a screw connection moves from a first hole region into a second hole region with a widening of the narrowed portions.

8. A method, comprising:
pivoting an actuator lever about a pivot axis under a force effect in an X direction resulting from a gearbox housing; and
during the pivoting, using the actuator lever to apply a force in a Z direction to a module mounted on a bulkhead to alter a position of the module mounted on the bulkhead, wherein a convex side of the actuator lever faces away from the brake booster such that the actuator lever is configured to apply an upward force to the brake booster in the Z direction during a pivotal movement.

9. The method of claim 8 , wherein the X direction is horizontal and the Z direction is vertical.

10. The method of claim 8 , wherein the application of the force in the Z direction by the actuator lever to the module displaces the module in the Z direction.

11. The method of claim 8 , wherein the module is a brake booster.

12. The method of claim 8 , wherein the module remains attached to the bulkhead when the position of the module is altered by the actuator applying the force in the Z direction to the module.

13. A brake booster device, comprising:
a brake booster mounted on a vehicle component; and
an actuator lever that, in response to a force applied to the actuator by a gearbox housing, pivots to move the brake booster upward,
wherein the actuator lever comprises an actuator arm that is pivotably coupled to a portion of the vehicle component,
wherein at least one pivot bearing pivotably couples the actuator arm to the vehicle component.

14. The brake booster device of claim 13 , wherein the vehicle component is a bulkhead.

15. The brake booster device of claim 13 , wherein a convex side of the actuator lever faces away from the brake booster such that the actuator lever is configured to apply an upward force to the brake booster in the Z direction during a pivotal movement.

16. The brake booster device of claim 13 , wherein the brake booster is rotated about a rotary axis in the Y direction as a result of the force of the actuator lever.

17. The brake booster device of claim 16 , wherein the rotary axis is located at a fastening point of the brake booster on the vehicle component.

18. The brake booster device of claim 16 , wherein the brake booster is displaced in the Z direction as a result of the force of the actuator lever.
