Electromagnetic braking system

Abstract

The invention relates to an electromagnetic braking system which comprises a reduction gear, a planetary gear train, a generator, a motor, a controller and a storage battery pack. The reduction gear is connected with vehicle wheels through a vehicle shaft. The reduction gear can move in the axial direction of the vehicle shaft under the driving of a brake coupling to control the mesh or separation of the reduction gear and the planetary gear train. One end of the planetary gear train is connected with the generator, and the other end of the planetary gear train is connected with the motor. The controller is respectively and electrically connected with the generator, the motor and the storage battery pack, the controller controls the generator to recycle energy consumed in a braking process and store the energy in the storage battery pack, and controls the motor to provide extra braking torque for the vehicle wheels. According to the electromagnetic braking system, an electromagnetic torque mode is used for providing the braking torque needed in the braking process, the problem of part abrasion caused by friction is avoided, braking performance is improved, and meanwhile the energy consumed in vehicle braking process can be recycled, and the energy utilization rate is improved.

Description

technical field [0001] The invention belongs to the application field of vehicle braking, and in particular relates to an electromagnetic braking system. Background technique [0002] Most of the existing vehicle braking systems use hydraulic braking systems, and the hydraulic braking systems use brake pads and brake discs to squeeze and generate sliding friction to achieve vehicle braking, that is, braking. The sliding friction between the brake pad and the brake disc will cause the contact surface of the brake pad and the brake disc to wear, resulting in shortened working life of the parts, and the parts need to be replaced when a certain degree of wear is reached. Moreover, the braking performance of the vehicle braking system will also decrease due to the wear and tear of components. [0003] During the friction between the brake pad and the brake disc, a large amount of heat energy will be generated. If the heat cannot be dissipated in time, the braking performance wil...

AI Technical Summary

Problems solved by technology

The sliding friction between the brake pad and the brake disc will cause the contact surface of the brake pad and the brake disc to wear, which will shorten the working life of the parts. When a certain degree of wear is reached, the parts need to be replaced

Moreover, the braking performance of the vehicle braking system will also decrease due to the loss of components

[0003] In the process of friction between the brake pad and the brake disc, a large amount of heat energy will be generated. If the heat cannot be dissipated in time, the braking performance will also be reduced.

This part of heat energy is converted from the kinetic energy of the vehicle generated by consuming gasoline and other resources. The dissipation of heat energy due to friction itself is a waste of energy, and this part of heat energy cannot be collected by a suitable method. be used, resulting in a waste of energy

[0004] The existing hydraulic braking system adjusts the braking force of the vehicle by controlling the load on the brake disc, but it is difficult to maintain the linearity of the braking force of the vehicle

Especially when the vehicle brakes for a long time, the brake pads and brake discs will overheat, and the linearity of the vehicle's braking force will be worse, which will make the driver feel uncomfortable braking.
