Problems solved by technology

[0003] Since the existing brakes use the principle of friction to brake, the friction lining will be worn out, and the tiny particles that are worn down will not only pollute the environment, but also cause a waste of resources
When the vehicle brakes continuously for a long time, especially when going down a long slope continuously, the high temperature due to frictional heat will cause the brake to fail and affect driving safety

Abstract

The invention relates to a brake with an auxiliary braking function. The brake comprises a brake disc, a left friction plate, a right friction plate, a caliper assembly, a brake piston, a fixing bracket, an electromagnetic coil set, an electromagnetic chuck assembly, a magnetorheological fluid brake, a brake pump shell, a first spring, an oil storage chamber, a first piston, a limiting check ring, a second spring, a second piston, a brake pedal, an angle sensor, a three-position three-way solenoid valve, an energy accumulator, a wheel speed sensor and a controller. The angle sensor, the wheel speed sensor, the electromagnetic coil set, the electromagnetic chuck assembly and the three-position three-way solenoid valve are all electrically connected with the controller. According to the brake, the magnetorheological fluid brake is adopted as auxiliary brake of a conventional hydraulic brake, not only can the brake response speed be increased, but also the loss of friction elements is reduced; hydraulic braking and magnetofluid adjusting braking are combined, and multi-stage braking can be simply and efficiently achieved; and the brake is of great significance in braking research of the disc brake.

Description

technical field [0001] The invention relates to the field of automobile brakes, in particular to a brake with an auxiliary braking function. Background technique [0002] The vehicle brake is one of the important safety components of the vehicle, and its performance directly affects the driving safety. At present, the vehicle mainly adopts hydraulic brake, and its working principle is that the brake hydraulic oil pushes the friction plate to press the brake disc to generate the braking force. In order to effectively ensure the braking efficiency of the vehicle, the ABS control system is installed on the vehicle to prevent the wheels from locking. [0003] Since the existing brakes use the principle of friction for braking, the friction plates will be worn out, and the ground fine particles will not only pollute the environment, but also lead to waste of resources. When the vehicle is continuously braked for a long time, especially when it continuously descends a long slope...
