Uniform type braking force balancing device and method of magnetic track brakes on both sides of rail train

Abstract

The invention discloses a uniform type braking force balancing device and method of magnetic track brakes on both sides of a rail train. According to the uniform type braking force balancing device and method of the magnetic track brakes on both sides of the rail train, a front pressure sensor and a rear pressure sensor are arranged between force transmission boards of the magnetic track brakes and a force transmission column of a train steering rack; each magnetic brake is provided with six iron cores, and every iron core is wound with three coils; the rear end of the first coil of every iron core is directly connected with the negative electrode of storage batteries, the front end of the first coil of every iron core is connected with the positive electrode of the storage batteries through switches K4 and K1; the rear end of the second coil of every iron core is directly connected with the negative electrode of the storage batteries, and the front end of the second coil of every iron core is connected with the positive electrode of the storage batteries through switches K3 and K1; the front end of the third coil of every iron core is connected with the positive electrode of the storage batteries through switches K2 and K1, and the rear ends of the third coils of the six iron cores are connected with the negative electrode of the storage batteries through switches K5, K6, K7, K8, K9 and K10 respectively. The uniform type braking force balancing device and method of the magnetic track brakes on both sides of the rail train can effectively avoid brake deviation of the train due to the fact that the magnetic track brakes on both sides of the same steering rack generate overlarge brake force difference in different gear positions, and accordingly improves the braking safety of the rail train.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle braking and safety, and relates to a braking force balancing device for magnetic rail brakes on both sides of rail trains. Background technique [0002] For trains using magnetic rail braking, a horizontal bogie is arranged under the bottom of the train body. There is a frame between the front and rear wheels on the same side of the train bogie. The bogie and the frame are fixed together by welding. On the frame Fix the brake suspension device, and hang the magnetic track brake under the brake suspension device. The magnetic track brake is located on the upper part of the train track, parallel to the track and arranged longitudinally along the front and rear of the track. There is a gap between them. Described magnetic rail brake generally has a plurality of electromagnets, and a plurality of electromagnets are distributed at equal intervals directly above the track and along the longitudin...
