US3628639A — Disc brake caliper-mounting means

Claim 1

Independent Claim 263 words

A mounting arrangement for mounting an axially movable element on an axially fixed element variously subject to side loading, axial loading, and vibrations, said mounting arrangement comprising: a fixed support; a pair of pin assemblies secured to said fixed support, each of said pin assemblies having a threaded center section, an elastic extension section on one side of said threaded section terminating in a head, an element support section, and a compression sleeve extending concentrically about the elastic extension section and engaging said head and said fixed support, each pin assembly being threaded into said fixed support under torque to elastically extend said elastic extension section and compress said sleeve; said axially movable element having at least two extended support and guide portions for each pin assembly, said support and guide sections having axially aligned openings therein receiving each of said pin assemblies on opposite sides of the pin assembly threaded section, an internal double-chamfered groove formed in the sidewall of each opening with the sidewall of each opening being radially spaced from the portion of said pin assembly over which it extends, a resilient deformable ring received in each groove in radially compressed relation between the adjacent outer surface of the pin assembly and the bottom of the groove and maintaining a radially spaced relationship between the pin assembly and the side wall of the opening at all times, said rings sliding on said pin assemblies upon forced axial movement of said element relative to said pin assemblies in one direction to readjust the position of said element on said pin assemblies.

Claim 2

Dependent Claim 263 words

A mounting arrangement for mounting an axially movable element on an axially fixed element variously subject to side loading, axial loading, and vibrations, said mounting arrangement comprising: a fixed support; a pair of pin assemblies secured to said fixed support, each of said pin assemblies having a threaded center section, an elastic extension section on one side of said threaded section terminating in a head, an element support section, and a compression sleeve extending concentrically about the elastic extension section and engaging said head and said fixed support, each pin assembly being threaded into said fixed support under torque to elastically extend said elastic extension section and compress said sleeve; said axially movable element having at least two extended support and guide portions for each pin assembly, said support and guide sections having axially aligned openings therein receiving each of said pin assemblies on opposite sides of the pin assembly threaded section, an internal double-chamfered groove formed in the sidewall of each opening with the sidewall of each opening being radially spaced from the portion of said pin assembly over which it extends, a resilient deformable ring received in each groove in radially compressed relation between the adjacent outer surface of the pin assembly and the bottom of the groove and maintaining a radially spaced relationship between the pin assembly and the side wall of the opening at all times, said rings sliding on said pin assemblies upon forced axial movement of said element relative to said pin assemblies in one direction to readjust the position of said element on said pin assemblies.

Claim 3

Dependent Claim 254 words

A disc brake caliper mounting for a brake having a disc and a caliper housing extending axially and circumferentially over a part of the disc and provided with spaced mounting orifices and a fixed support for the caliper housing, said mounting comprising: mounting bolt means spaced circumferentially of the disc and extending axially parallel thereto and fixedly secured to said fixed support and extending through said housing mounting orifices with the radially adjacent walls of said orifices and said bolt means being in spaced relation, at least one of the radially adjacent walls of each orifice and bolt means arrangement having internal grooves with slanted sidewalls providing wider groove openings than groove bases, annular resilient rings received in said grooves and about said bolt means in friction engaging relation and being compressed between said groove bases and the radially adjacent walls which are spaced from the walls having the grooves therein, said rings having deformable cross section areas due to side loading which are sufficient to prevent said bolt means adjacent walls from directly engaging said housing orifice adjacent walls, each of said bolt means having a head, a center threaded mounting section spaced therefrom and threaded into one of the openings in said fixed support, and a cylindrical spacer surrounding the bolt portion intermediate the head and the threaded section, said spacer having one end engaging said head and the other end engaging said fixed support, said spacer being loaded in axial compression and said intermediate bolt portion being loaded in axial tension.

Claim 4

Dependent Claim 254 words

A disc brake caliper mounting for a brake having a disc and a caliper housing extending axially and circumferentially over a part of the disc and provided with spaced mounting orifices and a fixed support for the caliper housing, said mounting comprising: mounting bolt means spaced circumferentially of the disc and extending axially parallel thereto and fixedly secured to said fixed support and extending through said housing mounting orifices with the radially adjacent walls of said orifices and said bolt means being in spaced relation, at least one of the radially adjacent walls of each orifice and bolt means arrangement having internal grooves with slanted sidewalls providing wider groove openings than groove bases, annular resilient rings received in said grooves and about said bolt means in friction engaging relation and being compressed between said groove bases and the radially adjacent walls which are spaced from the walls having the grooves therein, said rings having deformable cross section areas due to side loading which are sufficient to prevent said bolt means adjacent walls from directly engaging said housing orifice adjacent walls, each of said bolt means having a head, a center threaded mounting section spaced therefrom and threaded into one of the openings in said fixed support, and a cylindrical spacer surrounding the bolt portion intermediate the head and the threaded section, said spacer having one end engaging said head and the other end engaging said fixed support, said spacer being loaded in axial compression and said intermediate bolt portion being loaded in axial tension.

Claim 5

Dependent Claim 20 words

The mounting of claim 2, said spacer providing a caliper-mounting area engaged by at least one of said resilient rings.

Claim 6

Dependent Claim 37 words

The mounting of claim 2, each of said bolt means having a bolt section extending beyond said threaded section opposite said head and providing a caliper-mounting area engaged by at least another one of said resilient rings.
