A modular eddy-current brake device

Abstract

The invention relates to a modular eddy-current braking device. The device comprises a movable magnetic component and a static eddy-current reaction component, wherein the magnetic component and the eddy-current reaction component are oppositely arranged; the eddy-current reaction component comprises a magnetic conduction reaction layer and a non-magnetic-conduction / weak-magnetic-conduction reaction layer; and the magnetic conduction reaction layer and the non-magnetic-conduction / weak-magnetic-conduction are fixed through a fixing assembly. Compared with the prior art, the magnetic conductivereaction layer can counteract repulsive force generated during eddy-current braking, so the influence of the repulsive force on mobile equipment is adjusted, and the safety of the mobile equipment isimproved.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a modularized eddy current braking device. Background technique [0002] In the field of transportation, in order to ensure the safety of mobile transportation equipment, eddy current braking is often used in emergency situations to quickly reduce the speed of mobile equipment to zero to avoid safety accidents. Commonly used eddy current braking magnetic components are electromagnetic and permanent magnet. Electromagnetic magnetic components can be generated by energizing the coil. Its advantage is that the magnitude of the generated magnetic force can be adjusted by adjusting the current in the coil to achieve dynamic adjustment of the braking force. The disadvantage is that it needs to provide electric energy to the moving coil, and a special device must be provided. An electrical device with adjustable current levels powers the coil. Another type of magnetic component...

Problems solved by technology

Although this structure can generate a large braking force, there are two main problems at the same time. One problem is that when the braking force required by the condition changes, a new reaction plate needs to be replaced, resulting in a large replacement time and economic cost

Another problem is that during eddy current braking, in addition to generating braking force, it will also generate normal force. Since the eddy current braking reaction plate generally uses metal parts with good conductivity and non-magnetic conductivity, the normal force generated by it is repulsive force , which is opposite to the direction of gravity of the mobile device, the repulsive force generated will increase with the increase of the speed of the mobile device, and even exceed the weight of the mobile device in severe cases, causing the mobile device to fall off the running track, resulting in a greater safety hazard
