An integrated system of electromagnetic brake and friction brake for vehicle

Abstract

The invention discloses an electromagnetic brake and friction brake integrated system for a vehicle. The electromagnetic brake and friction brake integrated system is composed of one set of friction brake and one set of electromagnetic brake device. The friction brake is composed of a brake caliper body and a brake disc. The brake caliper body is clamped into the brake disc and fixedly connected to a brake caliper support. The friction brake and the electromagnetic brake device are arranged in an up-and-down mode relative to the brake disc. The electromagnetic brake device is composed of an electromagnetic brake supporting board, iron cores, magnet exciting coils and magnet yokes. The electromagnetic brake supporting board is in a U shape, the brake caliper support is fixedly connected to the upper portion of the U-shaped side wall of the electromagnetic brake supporting board, one ends of a plurality of iron cores are evenly fixed at the U-shaped bottom of the electromagnetic brake supporting board, and the iron cores are wound by the magnetic exciting coils. The other ends of the iron cores are connected with the magnet yokes. After the magnet exciting coils are electrified, the polarities formed by adjacent magnetic poles are opposite. The narrow installation space of a wheel edge brake is fully utilized, brake force exerted on the brake disc is vertically symmetric, and the brake disc is stressed evenly and stably. Slight chattering of the brake disc due to the fact that the brake disc is stressed with a single point is effectively relieved.

Description

technical field [0001] The invention relates to an integrated system of electromagnetic braking and friction braking used for braking or deceleration of automobiles, in particular to a device that uses eddy currents to generate braking torque to achieve braking effects. Background technique [0002] Friction brakes use the friction between the friction block and the brake disc to reduce the speed of the vehicle and finally stop the vehicle. During the braking process of the car, the friction block will continue to wear and the temperature will rise, which will directly affect the performance of the brake. At the same time, the wear of the friction block will also emit dust into the atmosphere and pollute the environment. While the car is braking, the friction between the friction block and the brake disc will also produce a lot of noise, especially in the case of continuous braking or frequent braking such as downhill or urban areas, the wear of the friction block is more se...
