Abstract
The present invention relates to a pad for brake caliper and to a brake caliper for disc brake provided with one or more of such pads. The pads are provided with one or more eyelets suitable to receive corresponding pins of the caliper. The pins define pin outlines, and the eyelets define eyelet outlines. The pin outlines have one or more curved pin contact portions with pin curvature radii, and the eyelet outlines have one or more curved eyelet contact portions with eyelet curvature radii. The contact between pads and pins at least partially occurs at the pin and eyelet contact portions. The eyelet curvature radii are higher than the pin curvature radii.
Claims20
A pad for a brake caliper of a disc brake suitable to be clamped against a braking band of a brake disc of said disc brake, said pad having eyelets for receiving corresponding pins of the caliper, in which said pins define pin outlines, and said eyelets define eyelet outlines, said pin outlines having one or more curved pin contact portions with pin curvature radii, and said eyelet outlines having one or more curved eyelet contact portions with eyelet curvature radii, so that the contact between the pad and the pins can occur at least partially at said pin and eyelet contact portions, wherein
- the eyelet curvature radii are greater than the pin curvature radii, and
- the eyelets and the pins are shaped and arranged so that contact between the contact portions of the pins and eyelets takes place solely at one point at a time and does not involve other points,
- the eyelets being arranged so that, following said braking band clamping, the pad is drawn on one or the other of the two pins as a function of the rotation direction of said brake disc,
- wherein the eyelet outlines of said two eyelets are mutually symmetric relative to a median axis of the pad, and
- wherein said eyelet outlines are closed and have an essentially rectangular or squared shape, with an outer upper corner, an outer lower corner, an inner lower corner, and an inner upper corner which are rounded, one or more of said rounded corners forming said eyelet contact portions.
A brake caliper for disc brake, comprising one or more pads suitable to be clamped against a braking band of a brake disc of the disc brake and provided with one or more eyelets receiving corresponding pins of the caliper, in which said pins define pin outlines, and said eyelets define eyelet outlines, said pin outlines having one or more curved pin contact portions with pin curvature radii, and said eyelet outlines having one or more curved eyelet contact portions with eyelet curvature radii, the contact between the pads and the pins occurring at least partially at said pin and eyelet contact portions, wherein the eyelet curvature radii are greater than the pin curvature radii, and
- wherein each eyelet and its corresponding pin are shaped and arranged so that contact between the contact portions of the pins and eyelets takes place solely at one point at a time and does not involve other points,
- each of said one or more pads comprises two of said eyelets, and wherein said brake caliper comprises two of said pins, the two pins and the two eyelets being arranged so that, following said clamping of the braking band, said one or more pads are drawn on one or the other of the two pins as a function of the rotation direction of said brake disc,
- wherein the eyelet outlines of said two eyelets are mutually symmetric relative to a median axis of the pad, and
- wherein said eyelet outlines are closed and have an essentially rectangular or squared shape, with an outer upper corner, an outer lower corner, an inner lower corner, and an inner upper corner which are rounded, one or more of said rounded corners forming said eyelet contact portions.
