The utility model relates to the technical field of railway vehicle control, in particular to a railway vehicle sanding air supply control system which solves the problem that an existing constant sanding air supply control system is not ideal in wheel rail adhesion improvement effect at a high vehicle speed and comprises a sanding air source and a sanding electromagnetic valve. The system further comprises an air supply control unit. The sanding air source is integrally provided with a proportional electromagnetic valve; the proportional electromagnetic valve is electrically connected with the air supply control unit; the proportional electromagnetic valve is connected with the sanding electromagnetic valve through a gas circuit; and the sanding electromagnetic valves are electrically connected with the train control and management system; according to the variable sanding amount method, the purpose that the sanding amount changes along with the vehicle speed is effectively achieved, especially under the emergency conditions of emergency braking, safety braking and the like, the appropriate sanding amount on the unit length rail surface can be guaranteed through the scheme, the wheel-rail relation can be better improved, the vehicle can fully play the braking performance, and the driving safety of a passenger in an emergent condition is ensured. Compared with a constant-speed sand spraying scheme, the constant-speed sand spraying method has the obvious advantages. The system is more suitable for being configured and applied to the tramcar.

    一种轨道车辆撒砂供风控制系统,涉及轨道车辆控制技术领域,解决现有恒定撒砂供风控制系统,在较高车速时对改善轮轨粘着效果不理想的问题,包括撒砂风源和撒砂电磁阀;还包括空气供给控制单元;撒砂风源集成安装有比例电磁阀;比例电磁阀与空气供给控制单元电连接;比例电磁阀与撒砂电磁阀通过气路连接;撒砂电磁阀均与列车控制和管理系统电连接;本发明可变撒砂量方法有效实现撒砂量随车速而变化,尤其是在紧急制动和安全制动等紧急情况下,该方案能保证在单位长度轨面上适当的撒砂量,因此能更好的改善轮轨关系,使车辆充分发挥制动性能,保障乘客在紧急情况下的行车安全,本发明较恒定速度撒砂方案有明显的优点。本发明更适合在有轨电车上配置应用。
