In said method, regulate and control brake shoe or brake lining pressure by the changing compressed air pressure piston thrust in regulation and control cylinder, when the piston thrust in cylinder is greater than spring force, brake shoe leaves wheel or brake lining and brake disc and disengages; When the piston thrust in cylinder is less than spring force, make brake shoe produce pressure to wheel, brake lining produces pressure to brake disc.When cylinder compressed air pressure is zero, piston thrust is zero, and the pressure that brake shoe produces wheel is maximum, the maximum pressure that brake lining produces brake disc.
According to said method build a kind of regulate and control the device of train brake shoe pressure, comprise cylinder body (2), epitrochoidal chamber (3), piston (4), piston rod (5), shock ring (6), pressure sensor (7), pressure sensor mount pad (8) retarding spring (9), normally closed braking electropneumatic valve (10) is often opened and is alleviated electropneumatic valve (11), in cylinder body (2), piston (4) is installed, be epitrochoidal chamber (3) in the driving surface side, outside of piston (4), the inward facing surface of piston (4) is provided with head, piston rod (5) is connected with at the head of piston (4), the front end of piston rod (5) and foundation brake rigging transmission levers are connected to brake shoe (13), brake shoe (13) is pressed on wheel (14), pressure sensor mount pad (8) is provided with pressure sensor (7), shock ring (6) is provided with between pressure sensor (7) and the inwall of cylinder body (1), retarding spring (9) is installed between pressure sensor mount pad (8) and the inward facing surface of piston (2).
The disk spring group that described retarding spring (9) forms for multi-disc disk spring.
The outside of the cylinder body (2) near epitrochoidal chamber (3) side is also provided with normally closed brake electric control valve (10) and often opens and alleviate electrically-controlled valve (11), often open alleviation electrically-controlled valve (11) and be connected with train pipe (12); Normally closed braking electropneumatic valve (10) is connected with air.
Owing to have employed above technical scheme, the present invention regulates and controls the method for brake shoe pressure or brake lining pressure by the pressure change piston thrust changing cylinder working chamber compressed air, not only simplify the brake system of existing rail vehicles, but also substantially increase existing vehicle driving safety performance.Even rail vehicles in the process of moving, its compressed air brake system all there occurs fault, and the present invention is stopped with also ensureing train safe.In addition, due to the present invention's employing is the brake power being used as brake shoe or brake lining by the elastic force of spring, and train conductor parks the time does not need parking brake equipment yet.The results showed, the present invention has following characteristics in use: compressed air consumption is few, and in braking procedure, idling braking time is short, can alleviate by implementation phase, glut can not occur, and accurately can control the brake-pressure of brake shoe in car brakeing process.So adopt the present invention effectively can improve the safety and reliability of train.Therefore, the present invention compared with prior art, the present invention not only have method reliable, easily implement and greatly can improve the advantage of train safe reliability, but also have structure simple, safeguard easily, cost of manufacture is low and completely can the advantage such as compatible existing rail vehicles.
