Abstract
A disk brake (1) usually comprises a caliper (2), a carrier (3) and friction means (8, 9). The caliper is slideably mounted on the carrier. To improve the braking performance of such a disk brake while reducing the manufacturing cost, the invention provides that a first friction means is retained rotationally by the carrier while a second friction means is retained rotationally by the caliper. The disk brake according to the present invention is also characterized in that the carrier has at least two guide pins (17, 18), the caliper being slideably mounted on the carrier via these two pins, the caliper having at least two bores (19, 20) able to receive one pin each.
Claims20
Disk brake (1) for a motor vehicle, comprising:
- a disk brake caliper (2), which caliper is provided with a hydraulic cylinder (4) having a piston (5) which is slideably mounted in this cylinder and with a nose (7), the caliper straddling a disk (6);
- a carrier (3) secured to the vehicle, the caliper being movably mounted on the carrier, the disk positioned and rotating between the nose and the piston;
- first and second friction means (8, 9) arranged on either side of the disk and configured to be applied against opposed faces (10, 11) of the disk by means of the piston and the nose, respectively;
- characterized in that the carrier (3) extends on only one side of a plane of the disk (6), and in that at least two pins (17, 18) extending from the carrier pass above the disk perpendicularly to the plane of the disk (6);
- and
- characterized in that the caliper is slideably mounted on the carrier via the pins, the caliper having a first bore and a second bore, each bore being configured to slideably receive one of the pins, the caliper supporting each pin on both sides of the plane of the disk (6), each bore being open to the carrier only in an area between the carrier and the plane of the disk, and the caliper receiving the pins only in the area between the carrier and the plane of the disk.
