Disc brake with giant magnetostrictive stress application function and method of disc brake

Abstract

The invention discloses a disc brake with a giant magnetostrictive stress application function and a method of the disc brake. The disc brake comprises a brake caliper body, a right brake cylinder, a right giant magnetostrictive stress application piston, a right brake block back plate, a right sealing ring, a right brake block, a brake liquid flow way, a guide column, a left brake block, a left brake block back plate, a left sealing ring, a left giant magnetostrictive stress application piston, a left brake cylinder, a brake disc, a piston body, a coil fixing cover, a gland, a mounting and dismounting clamping groove, an adjusting gasket, a coil channel, a wire outlet hole, an elastic gasket, an exciting coil, a coil framework and a giant magnetostrictive column. The characteristic that giant magnetostrictive materials can extend and has the good pressure resisting performance under the action of a magnetic field is utilized, force application is carried out on emergent brake through giant magnetostrictive column, the brake distance in emergent brake is further reduced, and driving safety is improved. In addition, the disc brake has the advantages of being simple and reliable in structure, good in compatibility to an existing brake system, free of affecting normal work of an ABS and the like.

Description

technical field [0001] The invention relates to a disc brake, in particular to a disc brake with giant magnetostrictive force-adding function and a method thereof. Background technique [0002] Automobiles are one of the most important means of transportation on land and play an irreplaceable role in national production and life. Among them, the brake system is one of the important assemblies of the car, which plays an important role in the safety and reliability of the car. Only a car with good braking performance and reliable braking system can give full play to its high-speed driving ability. power and ensure driving safety. At present, automobile brakes mainly include drum brakes and caliper disc brakes. Compared with drum brakes, caliper disc brakes have the advantages of good braking stability, good heat dissipation, small structural size, and easy maintenance. The application on various automobiles is more and more extensive. [0003] Existing disc brakes are mainl...

AI Technical Summary

Problems solved by technology

However, the maximum braking force of most servo brake systems is limited by the stroke of the master cylinder. When the stroke of the master cylinder reaches the maximum value, the braking force cannot continue to increase, and it is impossible to further increase the braking force in an emergency
