Sleeve for disk brake caliper and disk brake fitted with such a sleeve

摘要

The present invention relates to a sleeve (9) for a disk brake fitted with a caliper slidably mounted in a carrier by means of pins fixed rigidly to the caliper, said sleeve (9) being designed to receive one of said pins in a bore of the carrier.;According to the invention, such a sleeve is characterized in that it has ribs (10, 11) on a surface designed to come into contact with the carrier so that said ribs (10, 11) may be deformed in order to increase said contact surface when the sleeve (9) is compressed by an activation of the brake.

1. A sleeve (9) for a disk brake fitted with a caliper (1) slidably mounted in a carrier (2) by means of pins (6, 8) fixed rigidly to the caliper (1), said sleeve (9) being configured to receive one of said pins (6, 8) in a bore of the carrier (2), the sleeve (9) comprising first and second ribs (10, 11) on a surface configured to come into contact with the carrier so that said ribs (10, 11) may be deformed in order to increase said contact surface when the sleeve (9) is compressed by an activation of the brake, characterized in that the sleeve has a substantially cylindrical shape along a longitudinal axis (15), characterized in that the first ribs (10) are of trapezoidal shape extending along the longitudinal axis (15) of the sleeve (9) and may be deformed in order to increase said contact surface between the first ribs (10) and the surface, characterized in that the first and second ribs (10, 11) have different heights (H) measured from an outer surface of the sleeve (9) in a direction perpendicular to the longitudinal axis (15) of the sleeve (9).
