Abstract
A disk brake includes a brake disk with a preferred rotational direction, with a first brake pad with a first center of gravity on a first side of the brake disk, a second brake pad with a second center of gravity on a second side of the brake disk, and a caliper for transmitting the braking forces produced by the second brake pad to the first side of the brake disk. The second center of gravity is offset from the first center of gravity by a predetermined distance in the direction toward the side of the brake disk that trails when the disk is rotating in its preferred direction.
Claims13
A disk brake comprising
- a brake disk having a preferred rotational direction;
- a first brake pad (2) having a first center of gravity (S1) on a first side of the brake disk (4), and being the only brake pad on said first side of the brake disk
- a second brake pad (3) having a second center of gravity (S2) on a second side of the brake disk (4), and being the only brake pad on said second side of the brake disk
- a caliper (1) for transmitting braking forces produced by the second brake pad (3) to the first side of the brake disk (4);
- and
- a clamping device (5) which has a center axis and is configured to push the first brake pad (2) against the brake disk (4), wherein the center axis is perpendicular to the main plane of the brake disk (4) and extends through the first center of gravity (S1), wherein
- the second center of gravity (S2) is offset, both when the brake is at rest and when actuated, from the first center of gravity (S1) by a predetermined distance (V) in the circumferential direction toward the side of the brake disk (4) which trails when the disk is rotating in the preferred rotational direction (D), wherein the two centers of gravity (S1, S2) are the same radial distance away from the center axis of the brake disk (4) so that the centers of gravity are circumferentially unsymmetrical and radially symmetrical.
A disk brake comprising

- a sliding caliper (1) for transmitting braking forces produced by the second brake pad (3) to the first side of the brake disk (4);
- and
- a clamping device (5) which has a center axis and is configured to push the first brake pad (2) against the brake disk (4), wherein the center axis is perpendicular to the main plane of the brake disk (4) and extends through the first center of gravity (S1), wherein
- the second center of gravity (S2) is offset, both when the brake is at rest and when actuated, from the first center of gravity (S1) by a predetermined distance (V) in the circumferential direction toward the side of the brake disk (4) which trails when the disk is rotating in the preferred rotational direction (D), wherein the two centers of gravity (S1, S2) are the same radial distance away from the center axis of the brake disk (4) 50 that the centers of gravity are circumferentially unsymmetrical and radially symmetrical.
