Abstract

The invention relates to an independent control braking system for tram pre-warning avoidance, comprising a tram pre-warning avoidance module and a permanent magnet eddy current brake used for tram deceleration and braking controlled by the tram pre-warning avoidance module, the permanent magnet eddy current brake includes The rotor assembly, the stator assembly and the drive assembly, the stator assembly includes two pole piece stator disks and a permanent magnet stator disk, a plurality of pole pieces are evenly distributed along the circumference of the pole piece stator disk, and a plurality of pole pieces are evenly distributed along the circumference of the permanent magnet stator disk A pair of permanent magnets with NS poles arranged in the axial direction, each permanent magnet pair consists of two permanent magnet monomers with NS poles facing the same direction, the NS poles of adjacent permanent magnet pairs are facing opposite, and the drive assembly is connected to the permanent magnet stator plate . Compared with the prior art, the present invention assists the early warning and avoidance of the tram by setting the permanent magnet eddy current brake, which can realize a more frequent deceleration mechanism, is simple to control and responsive, greatly reduces the friction loss of the tram, and greatly improves the The operating efficiency of the tram.

Description

technical field

[0001] The invention relates to the field of tram operation control, in particular to an independently controlled braking system for tram pre-warning and avoidance. Background technique

[0002] The existing vehicle braking system can meet the requirements as the driver's normal speed regulation or parking, as well as braking in emergency situations. However, according to the operation requirements of trams, they share the right of way with social vehicles and pedestrians. Judging from the operation of trams in areas that have been opened, collisions with other vehicles at crossings or crowded areas have become a prominent problem, which affects the tramway. An important factor in the running quality of trams, which was one of the main problems of historically troubled trams.

[0003] Under normal conditions, trams generally use manual driving. At this time, the safety of train operation mainly depends on the driver’s manual observation and responsibility fo...
