Problems solved by technology

[0002] In the current vehicle braking system, the disc brake system is generally used. The main principle is to use hydraulic pressure to press the friction plate tightly to the brake disc of the wheel, thereby using friction to reduce the kinetic energy of the vehicle. When the wheel rotates at a high speed, the friction lining quickly hugs the brake disc, resulting in greater mechanical vibration and greater loss of the friction lining. Therefore, it is necessary to check and replace the friction lining regularly to prevent brake failure; In addition to disc brakes, there are also brake systems such as expansion brakes, but the basic principle is to rely on friction to decelerate, and there are also the same problems as disc brakes.

Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0014] exist figure 1 , figure 2 In the shown embodiment, the magnetic control brake includes a metal brake disc 1, and the center of the brake disc 1 has a shaft connecting body 2 consolidated with the wheel shaft. 11. Each through hole 11 is provided with a soft magnet 3 adapted to the shape of the through hole. The soft magnet 3 is made of silicon steel. A pair of coils 4 are arranged on both sides of the brake disc 1, and the pair of coils 4 are a pair of Helmholtz coils, which generate a parallel magnetic field orthogonal to the brake disc 1 when energized.

[0015] In the above-mentioned magnetic control brake, the distance between each of the through holes 11 and the outer edge of the brake disc 1 is not less than the height of a disc brake pad, so as to ensure that the disc brake pad can also be installed on the brake disc 1, so that the low-speed wheel...

Abstract

The invention provides a magnetic-control brake, which is applied to a vehicle. The magnetic-control brake comprises a metal brake disc, wherein through holes are uniformly and circumferentially distributed on the brake disc; soft magnets are arranged in the through holes; insulators are arranged outside the soft magnets and inside the through holes for insulation; and a pair of coils is respectively arranged on two sides of circumferences of the through holes and generates a magnetic field orthogonal to the brake disc during energization. The magnetic-control brake provided by the invention has the advantages of stableness, no vibration, brake noise and friction loss, and longer service life.

Description

Technical field [0001] The invention relates to a mechanical brake device, in particular, a brake applied to a wheel train of a vehicle, including a brake disc. Background technique [0002] In the current vehicle braking system, the disc brake system is generally used. The main principle is to use hydraulic pressure to press the friction plate tightly to the brake disc of the wheel, thereby using friction to reduce the kinetic energy of the vehicle. When the wheel rotates at a high speed, the friction lining quickly hugs the brake disc, resulting in greater mechanical vibration and greater loss of the friction lining. Therefore, it is necessary to check and replace the friction lining regularly to prevent brake failure; In addition to disc brakes, there are also brake systems such as expansion brakes, but their basic principle is to rely on friction to decelerate, and there are also the same problems as disc brakes.
