Guide pin for disc brake assembly, disc brake assembly including such a guide pin and method for producing a 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 at least one slot having a member, which is formed separate from the guide pin, and disposed therein to bias the guide pin in the bore thereby offsetting the guide pin axis relative to the bore axis. The member includes a first member formed from an elastomeric material and a second member formed from a metal material, wherein the second member is configured to retain the member in the slot.

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 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 when the guide pin is disposed in the at least one bore of the anchor bracket, the second axis of the guide pin is configured to be continually offset relative to the first axis of the at least one bore such that 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 at least one bore; wherein the guide pin includes at least one slot of a closed configuration and defines a first upper slot width at an upper open end thereof which is less than a second lower slot width at a lower closed bottom end thereof, the at least one slot has a member, which is formed separate from the guide pin, disposed therein and which member only, when disposed in contact against an inner diameter of the at least one bore, is operative to continually bias the guide pin in the at least one bore thereby offsetting the second axis of the guide pin relative to the first axis of the at least one bore, wherein the member includes a first member formed from an elastomeric material and a second member formed from a metal material, and wherein the second member is configured to be fixedly retained in the at least one slot so that the second member by itself is configured to retain the first member in the at least one slot.
