Problems solved by technology

Therefore, if we can make full use of the positive influence of the magnetic field on the braking friction behavior and apply it to the active control of the braking friction process of the automobile, the braking efficiency and reliability of the automobile brake can be significantly improved, and the braking performance of the driver can be enhanced. Comfortable operation, but because the existing automobile brake pads are all non-metallic and non-ferromagnetic materials, the magnetic field control of the automobile brake friction process does not yet have the most basic material conditions and technical basis

Abstract

The invention discloses a formula and manufacturing method for a car soft magnetic brake pad. The formula comprises, by weight, 6-18 parts of organic binding agents, 15-45 parts of reinforced fibers, 10-50 parts of friction performance conditioners, 3-10 parts of packing and 5-30 parts of soft magnetic materials. The manufacturing method comprises porphyrization, material mixture, thermo-compression formation, thermal treatment, surface processing and other processes. The formula and manufacturing method for the car soft magnetic brake pad have the advantages that the soft magnetic materials are added into an original car brake pad, so that the friction coefficient is increased, the abrasion rate is lowered, friction stability is improved, and the car soft magnetic brake pad well adapts to various complex braking conditions of a car; as the added soft magnetic materials are ferromagnetic substances, the car soft magnetic brake pad has high magnetic conductivity and saturation magnetic induction intensity, and the most basic material conditions are provided for magnetic field control in the brake friction process. The manufacturing method for the car soft magnetic brake pad is simpler, magnetism does not need to be charged in advance, and the friction action can be regulated and controlled in the braking process by regulating the magnitude of the magnetism through an external magnetic field.

Description

technical field [0001] The invention relates to a formula of a brake pad, in particular to a formula of an automobile soft magnetic brake pad and a preparation method thereof. Background technique [0002] The domestic research and development trend of friction materials for vehicles is not only limited to the simple requirements of reliable braking, but is developing towards the direction of braking safety, riding comfort, reducing pollution and protecting health. With the high-speed and heavy-duty of automobile transportation, traditional automobile brake pads can no longer meet the requirements of safety, reliability, comfort and environmental protection, mainly due to their large wear and serious damage to the counterpart, and continuous braking is easy to cause Brake failure etc. [0003] Traditional automobile brake pads generally use asbestos friction materials, semi-metal friction materials and asbestos-free organic friction materials. Asbestos brake pads have the ...
