Abstract

A guard plate for a disk brake of a vehicle includes a base element having at least one fastening section for arranging the base element in relation to a brake disk of the disk brake and at least one extension element. The at least one extension element may be movable relative to the base element and is configured to be moved and fixed between an initial position and at least one extension position.

First claim

That which is claimed:

1. A guard plate for a disk brake of a vehicle, the guard plate comprising:
a base element comprising a fastening section that affixes the base element on an inner, wheel axle side of the brake disk, the base element further comprising an aperture for receiving a wheel axle of the vehicle;
a plurality of extension elements; and
a plurality of adjusting mechanisms, each adjusting mechanism of the plurality of adjusting mechanisms comprising a plurality of linear sliding guides that movably couple each extension element of the plurality of extension elements to the base element;
wherein each extension element of the plurality of extension elements is linearly and radially movable in a direction away from an axis of rotation of the brake disk via the plurality of linear sliding guides and each extension element of the plurality of extension elements is fixable at an extension position;
wherein, with the plurality of the extension elements in the extension position, the plurality of extension elements form a gap between two of the extension elements within the plurality of extension elements that is aligned with a recess in the base element for receiving a portion of a hydraulic system for a brake caliper.

2. The guard plate of claim 1 , wherein each extension element of the plurality of extension elements are is arranged in relation to or on the base element by one of the adjusting mechanisms of the plurality of adjustment mechanisms, and
wherein each adjusting mechanism of the plurality of adjusting mechanisms is configured to enable a step-less or stepwise adjusting movement of one of the extension elements relative to the base element.

3. The guard plate of claim 1 , wherein each adjusting mechanism of the plurality of adjusting mechanisms has a plurality of latching positions via which a respective extension elements of the plurality of extension elements latches in a releasable but positionally stable manner in an initial position and in the extension position.

4. The guard plate of claim 1 , wherein the base element has a substantially circular or circular-segment-shaped main body, and the plurality of extension elements forms an outer contour that is arc-shaped, at least in one or more sections.

5. The guard plate of claim 4 , wherein the arc-shaped one or more sections of the outer contour have substantially a same arc-shape as an outer circumference of the brake disk or an inner circumference of a vehicle wheel.

6. The guard plate of claim 1
wherein a dirt collecting surface extending in a substantially flat manner relative to the brake disk is formed by the base element and the plurality of extension elements being in the extension position.

7. The guard plate of claim 6 , wherein the plurality of extension elements is provided along an outer circumference of the base element, wherein the plurality of extension elements comprise a first extension element;
wherein the plurality of linear sliding guides comprise a first sliding guide and a second sliding guide;
wherein the first extension element comprises the first sliding guide, and the first sliding guide couples the first extension element to the base element;
wherein the first extension element comprises the second sliding guide, and the second sliding guide couples the first extension element to the base element;
wherein the first sliding guide and the second sliding guide linearly translate to cause the movement of the plurality of extension elements relative to the base element.

8. The guard plate of claim 1 , wherein each of the extension elements within the plurality of extension elements is circular segment-shaped.

9. The guard plate of claim 1 , wherein the base element and/or the plurality of extension elements include a plurality of apertures for ventilating the brake disk of the disk brake.

10. The guard plate of claim 1 , wherein the base element comprises a central aperture for receiving a wheel axle through the central aperture.

11. The guard plate of claim 1 , wherein the guard plate is disposed within an inner, wheel-axle side cavity of a wheel and the plurality of extension elements extend toward an inner wall of the inner, wheel-axle side cavity of the wheel.

12. The guard plate of claim 1 , wherein, with the plurality of the extension elements in the extended position, the guard plate has a substantially continuous arc-shaped outer contour over greater than three quarters of a circular shape.

13. A disk brake for a vehicle, the disk brake comprising:
a brake disk;
an axle fastening for reception and fastening of the brake disk on a wheel axle of the vehicle;
a brake caliper arranged in relation to the brake disk for reception of brake pads, the brake caliper being configured to be operably coupled to a hydraulic system to operate the brake caliper; and
a guard plate provided adjacent to the brake disk, the guard plate comprising:
a base element comprising a fastening section that affixes the base element on an inner, wheel axle side of the brake disk, the base element further comprising an aperture for receiving a wheel axle of the vehicle;
a plurality of extension elements; and
a plurality of adjusting mechanisms, each adjusting mechanism of the plurality of adjusting mechanisms comprising a plurality of linear sliding guides that movably couple each extension element of the plurality of extension elements to the base element;
wherein each extension element of the plurality of extension elements is linearly and radially movable in a direction away from an axis of rotation of the brake disk via the plurality of linear sliding guides and each extension element of the plurality of extension elements is fixable at an extension position;
wherein, with the plurality of the extension elements in the extension position, the plurality of extension elements form a gap between two of the extension elements within the plurality of extension elements that is aligned with a recess in the base element for receiving a portion of the hydraulic system for the brake caliper.

14. The disk brake of claim 13 , wherein each extension element of the plurality of extension elements is arranged in relation to or on the base element by one of the adjusting mechanisms of the plurality of adjusting mechanisms, and
wherein each adjusting mechanism of the plurality of adjusting mechanisms is configured to enable a step-less or stepwise adjusting movement of one of the extension elements relative to the base element.

15. The disk brake of claim 13 , wherein each adjusting mechanism of the plurality of adjusting mechanisms has a plurality of latching positions via which a respective extension elements of the plurality of extension elements latches in a releasable but positionally stable manner in an initial position and in the extension position.

16. The disk brake of claim 15 , wherein one of the latching positions is an intermediate position between the initial position and the extension position.

17. The disk brake of claim 13 , wherein the base element has a substantially circular or circular-segment-shaped main body, and the plurality of extension elements form an outer contour that is arc-shaped, at least in one or more sections.

18. The disk brake of claim 17 , wherein the arc-shaped one or more sections of the outer contour have substantially a same arc-shape as an outer circumference of the brake disk or an inner circumference of a vehicle wheel.

19. The disk brake of claim 13 ,
wherein a dirt collecting surface extending in a substantia
