Problems solved by technology

One is a mechanical brake, the disadvantage is that it is laborious and often needs to be adjusted
The second type of hydraulic brake, the disadvantage is that the brake response speed is slow, and it is easy to leak hydraulic oil and cause the risk of brake failure
The third is the magnetic braking of the motor. The disadvantage is that the braking force cannot be adjusted according to actual needs, resulting in a strong sense of jamming and unsafe

Abstract

The invention provides a drum type electromagnetic brake device. The drum type electromagnetic brake device comprises an electromagnet, magnetic attraction pieces, lever mechanisms and friction pieces, one end of each lever mechanism is in transmission connection with the corresponding friction piece, the other ends of the lever mechanisms are in transmission connection with the magnetic attraction pieces, and the electromagnet is used for attracting the magnetic attraction pieces to move in the direction close to the electromagnet; and the magnetic attraction pieces are located between the friction pieces and the electromagnet, the faces, away from the magnetic attraction pieces, of the friction pieces are each an arc-shaped face, and the electromagnet is located in the centers of the arc-shaped faces of the friction pieces.

Description

technical field [0001] The present application relates to the technical field of brake devices, in particular to a drum type electromagnetic brake device. Background technique [0002] Electromagnetic braking devices are usually used on electric vehicles, which use electromagnetic damping to achieve braking. However, the damping braking effect generated by reverse electromagnetic reverse magnetic poles is poor, and it is difficult to achieve rapid braking and deceleration. Another braking method in the prior art usually uses a mechanical principle to achieve braking, and uses the friction of the brake pads to generate damping to achieve braking. However, this braking method requires the use of brake lines and a large grip to hold the brake handle , the brake structure is highly complex. [0003] There are three types of current braking methods. One is a mechanical brake, the disadvantage is that it is laborious and often needs to be adjusted. The disadvantage of the secon...
