Technical Field

The invention relates to the technical field of brake components, in particular to stable brake equipment based on a magnetic attraction principle.

Background

In the field of mechanical design, a brake is a very important component, and can effectively play a role in stopping or slowing a machine as required in time. With the continuous development of the technology, the brake is also more and more emphasized by people as a non-contact brake at present, taking the automobile field as an example, a more typical non-contact brake mechanism is mainly used for a retarder mechanism at present, and the successful use of the retarders such as an eddy current retarder, a hydraulic retarder and a permanent magnet type retarder improves the service performance of the automobile and plays a positive role. However, these retarder mechanisms also have certain problems, for example, the eddy current retarder has a relatively complex structure, needs to consume a certain amount of electric energy during operation, and has a relatively high requirement on the power supply of the automobile. The hydraulic retarder also has the problems of complex mechanism and large volume and mass, and meanwhile, the hydraulic retarder has slow braking response and large influence of the braking force on the speed of the vehicle; therefore, we propose a stable braking device based on the principle of magnetic attraction.
