Abstract
The invention discloses a magnetic rail braking device of a rail transit vehicle. The device comprises a power supply device and a magnetic rail brake. At least a first winding and a second winding are arranged in the magnetic rail brake, and the first winding and the second winding exert pressure on a wearing plate together. Energization of the first winding is controlled by a first controller, and energization of the second winding is controlled by a second controller. The electric current of the second winding is adjusted by the second controller through an electric current adjusting device. When braking is required, the first controller is started to energize the first winding to generate electromagnetic force used for resisting the elastic force of a supporting spring on a train. When the second controller is started, the second winding is controlled to generate superimposed electromagnetic force, the electric current is controlled to enable the second winding to generate magnitude-controllable electromagnetic force, and thus the purpose that the friction force is accurately controlled is achieved. Therefore, the braking force is changed according to the driving speed of the train so that the phenomenon of instability can be avoided. According to the control method of the magnetic rail braking device of the rail transit vehicle, the same technical effect can be achieved.
