Abstract
The present invention discloses brake lining and process of manufacture thereof using a recycled friction material to form a multilayered brake lining with varying densities.
Claims22
A method for generating friction material to form a brake lining of a drum brake system, comprising:
- a recycled friction material;
- a recycled fresh friction material;
- and
- a friction lining materials;
- wherein:
- a recycled friction material composition is generated using the recycled friction material, the recycled fresh friction material, and the friction lining materials.
3 more elements
A method for recycling brake linings of a drum brake system, comprising:
- providing used, uncontaminated friction material, constituting recycled friction material;
- crushing the recycled friction material to generate crushed recycled friction material;
- granulating the crushed recycled friction material to generate recycled friction material particles of a size below a first threshold size;
- separating recycled frictional material particles of size below the first threshold size from particles sizes below a second threshold size;
- wherein:
- recycled frictional material particles of size below the second threshold size constitute a finally granulated recycled frictional material particles for use in making brake linings.
3 more elements
A brake lining for a drum brake system, comprising:
- a first layer that includes recycled frictional material, and is pre-formed to have varying quantities of material throughout the first layer and includes at least one uneven surface;
- a second layer that includes fresh frictional material that is pre-formed on top of and in combination with the pre-formed first layer to form a dual layer brake lining that has varying quantities of material throughout, with areas having greater quantities of material generating higher density regions of the dual layer brake lining slowing abrasion of lower density regions generated by areas of lesser quantities of materials, with lower density regions of the brake lining improving brake quality;
- the at least one uneven surface mechanically mates with an inner surface of the second layer of the dual layer brake lining to facilitate mechanical resistance against shearing stresses experienced by the dual layer brake lining during braking process.
