Abstract

The invention concerns a guide pin for a brake caliper assembly and a brake caliper assembly for a vehicle disc brake, the vehicle disc brake comprising a brake disc that rotates about a rotation axis, the brake caliper assembly comprising: a brake caliper housing having a receiving section for a brake piston; a brake pad carrier configured to slidingly receive a pair of brake pads; and at least one guide pin configured to guide a relative movement between the brake caliper housing and the brake pad carrier. At least a first section of the guide pin has a cross-section comprising a main axis and a minor axis. A dimension of the cross-section along the main axis is longer than along the minor axis. An angle enclosed by the main axis and a radial direction is smaller compared to an angle enclosed by the minor axis and the radial direction.

Claims (23)

1 . A brake caliper assembly for a vehicle disc brake, the vehicle disc brake comprising a brake disc that rotates about a rotation axis, the brake caliper assembly comprising:

a brake caliper housing having a receiving section for a brake piston;

a brake pad carrier that is configured to slidingly receive a pair of brake pads; and

at least one guide pin that is configured to guide a relative movement between the brake caliper housing and the brake pad carrier;

wherein at least a first section of the guide pin has a cross-section comprising a main axis and a minor axis, wherein a dimension of the cross-section along the main axis is larger than along the minor axis,

wherein an angle enclosed by the main axis and a radial direction is smaller compared to an angle enclosed by the minor axis and the radial direction, and

wherein the first section of the guide pin has a protrusion.

2 . The brake caliper assembly of claim 1 ,

wherein the guide pin is mounted to one of the brake caliper housing or the brake pad carrier, and

wherein the first section of the guide pin is received in a guiding recess of another of the brake caliper housing or the brake pad carrier.

3 . The brake caliper assembly of claim 2 ,

wherein a cross-sectional shape of the guiding recess matches the cross-sectional shape of the first section of the guide pin.

4 . The brake caliper assembly of claim 2 ,

wherein the guiding recess comprises a recess for receiving the protrusion.

5 . The brake caliper assembly of claim 1 ,

wherein the angle between the main axis of the radial direction is 0° or between 0° and 45°.

6 . The brake caliper assembly of claim 1 ,

wherein the cross-section is elliptic.

7 . The brake caliper assembly of claim 1 ,

wherein the cross-section of the first section is hollow.

8 . The brake caliper assembly of claim 1 ,

wherein the cross-section of the first section is filled.

9 . A guide pin for a brake caliper assembly according to claim 1 .
