Double-brake disc type brake and automobile braking method

Abstract

The invention relates to the field of motor vehicle braking, in particular to a double-brake disc type brake. The brake comprises a first brake disc (5), a second brake disc (7), a first friction plate (4), a second friction plate (8), a friction plate with friction materials on the two sides (6), and a driving assembly for driving the friction plate to rub with the corresponding brake disc; and the driving assembly comprises a first brake clamp body (1), a second brake clamp body (10), a first piston (2) and a second piston (9). According to the double-brake disc type brake, the double brake discs can move in two directions at the same time, so that the abrasion of the friction plate is reduced, and the service life is prolonged; and meanwhile, on the premise that conventional problems are avoided, the braking torque is improved, and the braking torque is increased by 1.8 times under the condition that parameters are unchanged.

Description

technical field [0001] The invention relates to the field of motor vehicle braking, in particular to a dual-brake disc brake and an automobile braking method. Background technique [0002] Braking performance is one of the important performances to ensure the safety and reliability of vehicles, and the brake is the main actuator to achieve braking performance in the braking process, and it is an important way to ensure the realization of vehicle braking performance. Since the revision and implementation of GB7258-2017 "Technical Conditions for Motor Vehicle Operation Safety" in 2017, its relevant technical requirements have attracted widespread attention in the industry. Many parts configuration requirements have been upgraded, and the mandatory installation and use of disc brakes is one of the major changes. Traditional friction brakes are divided into two types: disc brakes and drum brakes. The disc brake uses hydraulic oil to push the piston in the brake caliper, and the...

Problems solved by technology

[0003] At present, with the development of automobile technology, the speed of the vehicle is getting faster and faster. When the car is running at high speed, braking will not only cause the friction lining of the friction brake to wear too fast, which will seriously affect the service life of the friction lining, but also cause the There is a lot of "squealing" noise caused by the friction between the block and the brake disc

At the same time, the greater the curb weight of the vehicle, the greater the braking torque required. Most of the existing braking methods use one-way drive, which causes the friction plates to be under the action of a considerable axial braking force for a long time, resulting in long braking time. , poor braking performance
