Abstract:

A new brake which included a structure reasonable pedal bilateral foundation braking mechanism and a energy recycling positive feedback braking was invented, based on the analysis of the unilateral foundation braking device and the motor reverse braking，to improve the braking performance of mine electric locomotive. This system solves the problems of the eccentric wear of brake-tile and the energy waste of resistance braking, shortens the braking response time effectively, increases the braking force and the braking distance, and improves the braking reliability visibly .In power system operation, in order to reduce energy loss and improve the utilization rate of power supply equipment, the regenerative braking is needed. In practical applications, satisfied results and remarkable economic effects were obtained.

Key words: Motor vehicle brake, Pedal bilateral foundation braking mechanism, Regenerative braking, Brake distance, Partial abrasion of brake shoe
