Embodiment Construction

[0028] The following detailed description illustrates the invention by way of illustration and not limitation. This description clearly enables one skilled in the art to make and use the invention, describing various embodiments, matching modifications, variations, substitutions, and uses of the invention, including what is presently believed to be the best mode of carrying out the invention.

[0029] Referring to FIG. 1 , a brake shoe part of the present invention is marked with 10 . The brake shoe member 10 comprises a cylindrically curved brake shoe plate forming part of the surface of the cylinder. The brake shoe member 10 is provided with one or more connection points 14 on a lower surface 16 adapted to allow easy connection of the brake shoe member 10 to a support structure (not shown) of a motor vehicle wheel. The specific characteristics of the connection point 14 vary depending on the specific application for which the brake shoe assembly 10 is intended.

Abstract

A vehicle brake shoe component (10) having a rigid back plate (12) incorporating a plurality of extensions (100) protruding through the brake friction material matrix (22) to the brake shoe component (10 ) of the external friction surface (24). Each extension (100) is configured to cooperate with the brake friction material matrix (22) to simultaneously engage an opposing friction element (28) with the friction material (22), enhancing the durability of the component (10) during initial use. Static and dynamic friction properties that exceed those obtained using one of the brake friction material (22) or the protruding portion (100).

Description

[0001] This application claims priority from US Patent Application No. 11 / 037,721 filed on January 18, 2005 as the prior application. Background technique [0002] The present application mainly relates to vehicle braking components, and in particular to a high friction braking component incorporating a plurality of backplate extensions passing through a matrix of friction material, which can be used in vehicle parking brake and vehicle emergency braking systems on vehicles, These vehicles are equipped with an independent typical, full servo braking system (disc or drum) on each of its four wheels. [0003] Vehicle drum-type friction-rotating devices typically include a vehicle brake shoe assembly with a friction matrix that contacts the inner cylindrical surface of a rotating brake drum to generate friction and correspondingly slow, stop, or hold the vehicle at a standstill or parking location. A disc brake system includes a caliper assembly having opposing friction pads in ...
