Abstract

The invention belongs to the field of rail train braking and particularly relates to a rail eddy current brake. The rail eddy current brake comprises connecting beams and a pair of excitation units and is characterized in that the pair of excitation units are parallelly arranged on two sides of the connecting beams, the excitation units are mounted on a turning rack, and each excitation unit comprises a magnet yoke beam and a plurality of excitation windings; a lifting system and an air gap adjusting system are respectively arranged at the front end and the rear end of each excitation unit, the lifting is located on the inner side of the air gap adjusting system, and the air gap adjusting system is used for adjusting the distance between the excitation unit and a rail. The rail eddy current brake has the advantages that by the rail eddy current brake, the braking effect and operation stability of a rail train can be increased; the distance measuring sensors of the air gap adjusting systems measure air gaps air, and air cylinder air feeding or discharging is performed through air pumps to automatically adjust the air gaps so as to satisfy braking requirements.

Description

Technical field [0001] The invention belongs to the field of rail train braking, and particularly relates to a rail eddy current brake. Background technique [0002] As train speeds increase, train braking systems are facing increasingly severe challenges. For traditional tread or disc brakes, the brake device absorbs a lot of energy when the train is braking, causing the tread and brake shoes or the brake disc and brake pads to deform and crack due to wear and frictional heat, causing the tread Or the brake disc has abrasion and deformation, which aggravates wheel / rail noise or brake disc noise, and at the same time shortens the maintenance cycle of the brake device, and intense friction can also cause a lot of harmful dust pollution. Therefore, it is very important to study non-friction braking technology. Non-friction braking mainly includes resistance braking, regenerative braking and eddy current braking. Restricted by the principle of braking, resistance braking and rege...
