Embodiment Construction

[0016] Such as figure 1 As shown, the present invention has two brake discs, which are respectively the first brake disc 1 and the second brake disc 6, and these two brake discs are used to replace the single disc brake disc of the traditional disc friction brake. , retain the original friction brake assembly (including brake blocks, brake calipers, etc.). The brake caliper 9 is arranged on the first brake disc 1 and is fixedly installed with the vehicle body. Under the control of the hydraulic brake circuit, the brake block presses against the first brake disc 1, and the first brake disc 1 generates frictional braking force.

[0017] An electromagnetic braking device is arranged on the second brake disc 6. The electromagnetic braking device includes several groups of excitation coils, each group of excitation coils is composed of two coil windings 4 and two iron cores 8, and the coil windings 4 are wound on the iron cores. 8, two coil windings 4 and two iron cores 8 are sym...

Abstract

The invention discloses a friction and electromagnetism integrated brake witha double disk structure for carrying out brake and deceleration on car. The brake comprises a first brake disk and a second brake disk. A brake clip is arranged on the first brake disk, and an electromagnetism brake device is arranged on the second brake disk. The electromagnetism brake device comprises several sets of excitation coils. Each set of the excitation coils comprises two coil windings and two iron cores. The coil winding is wound on the iron core. The two coil windings and the two iron cores are symmetrically distributed on both sides of the second brake disk. An aluminum support is arranged in the middle of the two coil windings. The friction and electromagnetism integrated brake with the double disks distributes brake torque of an electromagnetism brake anda friction brake through precise control, realizes brake heat shunt, avoids brake heat failure, and improves safety performance of vehicle brake.

Description

technical field [0001] The invention relates to a brake installed on a car to brake and decelerate the car. Background technique [0002] Traditional friction brakes on cars are divided into two types: disc brakes and drum brakes, which use the friction between the brake pads and the brake disc or brake drum to reduce the speed of the vehicle and eventually stop it. At present, the commonly used friction brakes are mainly disc brakes. The hydraulic oil is used to push the piston in the brake caliper to move, and the piston presses the brake block to the brake disc, and the two generate friction to achieve braking. [0003] When the vehicle is running at high speed, braking not only wears the brake shoes of the friction brake very severely, but also produces a lot of harmful dust. At the same time, the friction between the brake pad and the brake disc will generate a lot of noise. When the car is in emergency braking, the action time of the brake and the braking force have ...
