Abstract

An exemplary brake booster device includes, among other things, a brake booster mounted on a vehicle component, and an actuator that, in response to a force applied to the actuator by a gearbox housing, pivots to move the brake booster upward. The actuator includes at least two pivot elements spaced from each other, and a displacement mounted in a jointed manner between the at least two pivot elements.

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
a deformable actuator which is formed by at least two pivot elements and a displacement element, the two pivot elements are mounted at a spacing from one another on a vehicle component such that they are pivotable about respective rotary axes extending in a Y direction, the displacement element is mounted in a jointed manner between the two pivot elements,
wherein the actuator is configured to pivot about the rotary axes of the two pivot elements under a force effect in an X direction resulting from a gearbox housing, whereby the actuator applies a force to the brake booster in a Z direction, as a result of which the position of the brake booster is alterable, wherein the actuator is mounted below the brake booster and applies an upward force to the brake booster in the Z direction during the pivoting.

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

3. The brake booster device of claim 2 , wherein the tilting 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.

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 a pivot element of the actuator has an angled design providing a contact surface to make contact with the brake booster.

7. The brake booster device of claim 1 , wherein a plurality of rotary joints between the displacement element and the pivot elements, a plurality of rotary axes between the pivot elements and the vehicle component, or both, that are formed by material portions having a rigidity which is lower than the rigidity of the pivot elements, the displacement element, or both.

8. 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.

9. A method, comprising:
pivoting a deformable actuator which is formed by at least two pivot elements and a displacement element, wherein the two pivot elements are mounted at a spacing from one another on a vehicle component such that they are pivotable about rotary axes, and the displacement element is mounted in a jointed manner between the two pivot elements, the pivoting about the rotary axes of the two pivot elements in response to a force applied by a gearbox housing in an X direction; and
during the pivoting, using the actuator 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.

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

11. The method of claim 9 , wherein the application of the force in the Z direction by the actuator to the module displaces the module in the Z direction.

12. The method of claim 9 , wherein the module is a brake booster.

13. The method of claim 9 , 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.

14. A brake booster device, comprising:
a brake booster mounted on a vehicle component; and
an actuator that, in response to a force applied to the actuator by a gearbox housing, pivots to move the brake booster upward, the actuator including at least two pivot elements spaced from each other and a displacement mounted in a jointed manner between the at least two pivot elements.

15. The brake booster device of claim 14 , wherein at least two pivot elements are pivotably connected to a vehicle component such that the at least two pivot elements are pivotable relative to the vehicle component about respective rotatory axes extending in a Y direction.

16. The brake booster device of claim 14 , wherein the force applied to the actuator is in a horizontal force in an X direction.

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

18. The brake booster device of claim 14 , wherein the brake booster is rotated about a rotary axis in the Y direction in response to the upward movement of the actuator.

19. The brake booster device of claim 18 , wherein the brake booster slides upwards relative to the vehicle component in response to the upward movement of the actuator.

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