Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of braking equipment, in particular to a magnetically controlled brake. Background Art
[0002] Under the existing technology, hydraulic disc brakes are used as key components in the braking systems of modern electric vehicles. Their efficiency and stability are directly related to driving safety. The core principle of this braking method lies in using a hydraulic system to precisely control the braking force, ensuring that the vehicle can quickly decelerate or stop in case of an emergency. Specifically, when the brake pedal is actuated, this action is converted into an increase in the pressure of the brake fluid in the master cylinder through a series of mechanical and hydraulic connection devices. Subsequently, this high-pressure hydraulic fluid is quickly distributed to the inner and outer wheel cylinders of each wheel. Inside the wheel cylinder, the hydraulic pressure pushes the piston to move outwards, and these pistons tightly press the brake pads (or brake shoes) fixed on both sides of the brake disc. As the contact area between the brake pads and the rotating brake disc increases, the frictional force between them also increases, thereby generating a powerful braking torque, causing the wheels to decelerate and finally stop rotating.
[0003] However, under long-term high-intensity use or extreme working conditions, the hydraulic disc brake may face the problem of system overheating. When the internal temperature of the braking system is too high, part of the brake fluid may vaporize, forming tiny bubbles and mixing into the hydraulic fluid. These bubbles move around in the hydraulic system, not only occupying the space that should originally be occupied by the hydraulic fluid, but also seriously interfering with the stable transmission of the hydraulic pressure, resulting in a slower braking response, uneven braking force, or even complete loss of braking force, posing a great threat to driving safety.
[0004] In order to more effectively prevent the braking system from failing due to overheating, it is urgent to develop a magnetically controlled brake. Content of the Utility Model
[0005] The applicant of the present invention aims at the above-mentioned shortcomings in the existing production technology, and provides a magnetically controlled brake, which generates a repulsive magnetic force of the same polarity as the driving force through an electromagnetic field, different from the hydraulic pressure mode of the existing hydraulic brake, avoiding the possible vaporization phenomenon of part of the brake fluid after the system is overheated, and ensuring driving safety.
[0006] The technical solution adopted by the utility model is as follows: a magnetically controlled brake, including a caliper body with a brake disc as the central vertical plane and symmetrically arranged on both sides of the brake disc; a brake assembly for braking the brake disc is arranged in each caliper body; the structure of the brake assembly is as follows: including a brake shoe assembly arranged opposite to the brake disc, and the other end of the brake shoe assembly is against a brake power source; a coil is wound on the brake power source; the brake power source generates an electromagnetic field that repels the brake shoe assembly on the same side through the coil, and pushes the brake shoe assembly on the same side to move toward the brake disc under the action of the repelling electromagnetic field; an elastic member is arranged between the brake shoe assembly and the brake disc.
[0007] As a further improvement of the above technical solution:
[0008] In one embodiment, when the brake assembly brakes the brake disc, it at least includes a relaxed state in which the brake shoe assembly is not in contact with the brake disc and a braking state in which the brake shoe assembly is in contact with the brake disc, wherein:

[0010] In the braking state, the coil on the braking power source is energized, and an electromagnetic field that repels the brake shoe assembly is generated on the braking power source.

[0014] In one of the embodiments, the braking power source is fixed inside the corresponding caliper body by bolts.
