Light disc type brake block

Abstract

The invention discloses a light disc type brake block. The light disc type brake block comprises a friction material block and a gasket which are fixed into a single unit through adhesive and heating-pressurizing bonding; the gasket at least comprises a long fiber structure layer, the long fiber can be metal long fiber or other long fiber, such as fiber reinforced polymer CFRP. The light disc type brake block is capable of simultaneously meeting the bonding area and high intensity requirements, for example, 2011-231875 of Japanese patent documents. The light disc type brake block has the same intensity as an existing disc type brake block, avoids the warping deformation problem due to heat shrinkage and meets the energy conservation and environmental protection requirements of a vehicle.

Description

technical field [0001] The invention discloses a light-weight disc brake pad, which belongs to the technical field of brake pad manufacturing according to the International Patent Classification (IPC), and relates to a disc (disc) brake pad (manufactured) composed of a lining and a friction material block. moving plate), especially used in brake pads of rail vehicles, automobiles, motorcycles, industrial machinery, and agricultural machinery. Background technique [0002] Disc brake pads used in rail vehicles, automobiles, and motorcycles are generally composed of linings (usually steel plates), adhesive layers, and friction materials. The aforementioned friction materials are composed of reinforcing fibers, organic materials, and friction adjustment materials. The agent is fixed on the lining. The solvent-based adhesive of heat-reactive resin is sprayed or coated on the lining and then dried, or an adhesive film is sandwiched between the lining and the friction material bl...

AI Technical Summary

Problems solved by technology

[0006] For the fixing method of CFRP and lining mentioned above, due to the different elastic modulus of CFRP and steel plate, when the lining is cooled to the range close to the ambient temperature, the steel plate will be warped and deformed due to the thermal contraction of CFRP, and its microscopic essence is the current fiber Reinforced resins generally use short fibers or particles, without stretching or relying on each other, and warping problems will occur when heat shrinks

If the aforementioned problems do not occur, the thickness of the steel plate needs to be increased, so the purpose of reducing the lining cannot be achieved
