Embodiment Construction

[0060]In the process of realizing the present application, the inventor found that although the existing electromagnetic brake can meet the space requirements of the micro-rail vehicle in terms of size, it is limited by the size of the running mechanism of the micro-rail vehicle, causing the electromagnetic brake to fail due to the small braking force. It cannot meet the braking performance requirements of micro-rail vehicles.

[0061] In view of the above problems, the embodiment of the present application provides a micro-rail vehicle and its electromagnetic brake. The electromagnetic brake has the characteristics of large braking force, so as to solve the problem that the existing electromagnetic brake cannot satisfy the braking performance of the micro-rail vehicle due to the small braking force. asked questions.

[0062] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present a...

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.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to a micro-rail vehicle and its electromagnetic brake. Background technique [0002] The braking system of traditional rail vehicles generally adopts air braking or hydraulic braking, but due to the characteristics of large volume and complex structure, the air braking system and hydraulic braking system are not suitable for micro-rail vehicles. The inventor found that although the traditional electromagnetic brake can meet the space requirements of the micro-rail vehicle in terms of size, the electromagnetic brake cannot meet the braking performance of the micro-rail vehicle due to the small braking force due to the size limitation of the running mechanism of the micro-rail vehicle. Require. Contents of the invention [0003] The embodiment of the present application provides a micro-rail vehicle and its electromagnetic brake. The electromagnetic brake has the cha...
