Guide pin for disc brake assembly and disc brake assembly including such a guide pin

摘要

A disc brake assembly having a guide pin disposed in a bore of an anchor bracket such that a guide pin axis is offset relative to a bore axis whereby there is provided at least one defined point of contact between only a portion of the guide pin and a portion of an inner surface of the bore. The guide pin includes a groove formed therein, the groove defines a groove axis which is offset relative to the guide pin axis, and a resilient member is disposed in the groove which is operative to bias the guide pin in the bore such that the guide pin axis is offset relative to bore axis to provide the at least one defined point of contact between only a portion of the guide pin and a portion of the inner surface of the bore.

主权项

1. A disc brake assembly comprising:
an anchor bracket having at least one bore formed therein, the bore defining a first axis; and a guide pin adapted to be disposed in the at least one bore of the anchor bracket and configured to slidably support a brake caliper relative to the anchor bracket, the guide pin defining a second axis; wherein the guide pin includes at least one annular groove formed therein, the groove defining a third axis which is offset and substantially parallel relative to the second axis of the guide pin, the at least one groove having an annular resilient member disposed therein which member engages and is compressed against an inner surface of the at least one bore such that the member only is operative to continually bias the guide pin in the at least one bore whereby the second axis of the guide pin is continually offset and substantially parallel relative to the first axis of the at least one bore such that there is provided only by the member, due to the member engaging and being compressed against the inner diameter of the at least one bore, at least one defined point of contact between a portion of the guide pin and a portion of an inner surface of the at least one bore, wherein the first axis of the at least one bore is located between the second axis of the guide pin and the third axis of the groove.
