Abstract

The invention discloses a permanent magnet braking and frictional braking combined brake for automobile braking or deceleration and a braking method. The brake comprises a permanent magnet braking device and a frictional braking device, wherein the permanent magnet braking device comprises a magnetic conductive plate, a magnetic conductive ring, a magnetic conductive sleeve and a permanent magnet and is symmetrically distributed at both sides of a brake disk; the magnetic conductive sleeve is internally provided with the permanent magnet which reciprocates along the axial direction of the magnetic conductive sleeve; one end of the permanent magnet close to the braking disk is sheathed with the magnetic conductive ring in a clearance way, and the magnetic conductive ring is fixedly connected with the magnetic conductive sleeve; the outer side of the magnetic conductive ring is provided with the magnetic conductive plate which is fixedly connected with the permanent magnet; during emergency braking, the permanent magnet braking device and the frictional braking device jointly take effect; during non-emergency braking or long slope braking, if a vehicle speed is higher than 30km / h, only the permanent magnet braking device brakes; if the vehicle speed is lower than 30km / h, only the frictional braking device brakes; and the permanent magnet braking and frictional braking combined brake has good heat-fading resistance, reduces the frictional braking abrasion, prolongs the service life of the brake and reduces the noise of the whole brake.

Description

technical field [0001] The invention relates to a brake used for braking or decelerating an automobile, in particular to a brake combined with a permanent magnet brake and a friction brake and a braking method thereof. Background technique [0002] Traditional automobile brakes are divided into two categories: disc brakes and drum brakes. Both disc brakes and drum brakes are friction brakes. The friction between the friction block and the brake disc or brake drum reduces the speed of the vehicle and finally stops it. During the braking process of the car, the friction block will continue to wear and the temperature will increase. The continuous rise will directly affect the performance of the brake. At the same time, a large amount of wear of the friction block will also emit dust into the atmosphere and pollute the environment. While braking, the friction between the friction block and the brake disc or brake drum also produces a lot of noise. Especially in the case of co...
