Embodiment Construction

[0032] In the following description and claims, expressions such as "longitudinal direction", "transverse direction", etc. will be used in a non-limiting manner with reference to the dihedron (L, T) represented in the drawings and the definitions given in the description.

[0033] In the following description, the same reference numerals denote the same or equivalent parts or parts having similar functions.

[0034] figure 1 and image 3 A caliper 10 and a cover 12 of an automotive disc brake (not shown) realized according to the prior art are shown.

[0035] In a known manner, the disc brake comprises a fixed cover 12 comprising two stepped holes 29 , 31 parallel to axes A, B, each stepped hole comprising at least one first recess 28 , 30 .

[0036] The brake also comprises a caliper 10 mounted axially relative to a fixed cover 12 in a slidable manner along a longitudinal direction parallel to the axes A and B.

[0037] The caliper 10 is slidably mounted relative to the co...

Abstract

The invention relates to a motor vehicle disc brake having a carrier (12) which has two bores, a sliding caliper, and two guide pins (16) for guiding the caliper, each of which has a guide section (24) which is mounted so as to slide in a section (28) of a bore, characterized in that each pin (16), in cooperation with the wall of the bore (29), delimits an axial channel (65), and each pin (16) receives a tubular sealing cap, an inner wall of which has at least one radial groove or radial slot which communicates with the axial channel (65) delimited by the associated pin.

Description

technical field [0001] The invention relates to an automobile disc brake. Background technique [0002] In particular, the present invention relates to an automobile disc brake, said automobile disc brake comprising: [0003] - a cover comprising two stepped holes of parallel axes, each of said two stepped holes comprising at least one first portion; [0004] - calipers mounted axially relative to the cover in a slidable manner; [0005] - two pins of parallel axes, each of said two pins comprising an axial attachment end and at least one guide for axially sliding said caliper relative to said cover, said axial attachment end attached to said caliper, said at least one guide extending from a free end of an associated pin and slidably mounted in said first portion of an associated stepped hole of said cover. [0006] In this design, for the purpose of tightness and protection of the sliding guide area, the guide of each pin is slidably mounted in a concealed or closed firs...
