URBAN TRAM BRAKING SYSTEM

WIPO Patent Application WO/2013/134918

A1

An urban tram braking system, comprising a brake instruction generation system, a brake control system and an anti-skid system; the brake control system comprises a brake electronic control unit (BECU) and a brake control unit (BCU); the brake instruction generation system transmits a brake instruction to the BECU; according to the brake instruction and the loading force detected by a loading pressure sensor, the BECU calculates and provides a required brake force to a traction control unit; the traction control unit feeds the dynamic brake force signal back to the BECU; the BECU calculates the air brake force to be replenished, and controls the BCU to generate brake cylinder pressure so as to achieve brake control; the brake instruction generation system is provided with a driver controller, an emergency brake switch and a logic control unit connected to the emergency brake switch; the anti-skid system comprises a speed sensor disposed on a wheel axle and an anti-skid exhaust valve located on a brake cylinder tube; the speed sensor detects and transmits a speed signal to the BECU; and the BECU controls the action of the anti-skid exhaust valve according to the speed signal.
