Abstract

The invention relates to the technical field of rail traffic, in particular to a micro-rail vehicle and an electromagnetic brake thereof. The electromagnetic brake comprises a magnetic yoke, an armature, an excitation coil, a fixing sleeve, a fixing disc, an elastic piece, two or more braking discs and movable discs; the two or more braking discs can all slide in the axial direction of the fixingsleeve, and sleeve the peripheral face of the fixing sleeve in a relatively fixed mode in the circumferential direction of the fixing sleeve; and each movable disc is sandwiched between every two adjacent corresponding braking discs. According to the electromagnetic brake, the friction area of the braking discs can be increased through the arranged two or more braking discs and the movable discs arranged between the braking discs, then braking friction force and braking torque are increased, and thus the electromagnetic brake has the characteristic of large braking force so as to solve the problem that an existing electromagnetic brake cannot meet the braking performance requirement of the micro-rail vehicle due to the small braking force.
