Description
技术领域technical field
本发明大致涉及轨道车辆技术领域，并且特别涉及用于轨道车辆的空气制动系统。The present invention relates generally to the field of rail vehicle technology, and in particular to air braking systems for rail vehicles.
背景技术Background technique
传统的轨道交通车辆制动系统一般采用减压的方式来实现，国内传统的轨道交通车辆制动系统实现制动的制动设备一般为三通阀或分配阀，例如用于货运列车GK型的三通阀、用于客运列车GL3型的三通阀，或103型、104型分配阀。传统制动设备的特点是当与制动机连接的列车管气压降低时，制动系统制动；而当列车管气压升高时，制动系统缓解。列车管减压量的大小相应决定了制动气缸的输出压力，进而驱动转向架上的制动夹钳和闸片或踏面制动单元和闸瓦作用于车轮，通过车轮和轨道之间的相互作用实现列车制动系统功能。The traditional rail transit vehicle braking system is generally realized by decompression. The domestic traditional rail transit vehicle braking system generally uses three-way valves or distribution valves, such as GK type for freight trains. Three-way valve, three-way valve for passenger train GL3 type, or type 103, 104 distribution valve. The characteristic of traditional braking equipment is that when the air pressure of the train pipe connected to the brake machine decreases, the brake system brakes; and when the air pressure of the train pipe increases, the brake system releases. The decompression amount of the train pipe determines the output pressure of the brake cylinder accordingly, and then drives the brake caliper and brake pads on the bogie or the tread brake unit and brake shoes to act on the wheels, through the interaction between the wheels and the track The function realizes the function of the train braking system.
通过减压制动的方法实现列车制动系统制动的功能，往往会造成列车中前后车辆的制动状态不一致从而造成较大的纵向冲击，这主要是由于减压制动时列车管中压缩空气的压力变化传递造成的，纵向冲击给列车运行带来巨大的安全隐患，尤其是货车，制动时产生巨大的纵向冲击力会直接将车间缓冲装置损坏。另外，由于传递制动时列车管中的压缩空气压力变化的压力波传播速度有限，这样就会导致列车的空走时间加长，进而会导致制动距离的延长。制动距离的延长会给列车，尤其是高速列车的运行构成较大的安全隐患。Realizing the braking function of the train braking system through the method of decompression braking will often cause the braking state of the front and rear vehicles in the train to be inconsistent, resulting in a large longitudinal impact, which is mainly due to the compression of the train tube during decompression braking. Due to the transmission of air pressure changes, the longitudinal impact brings huge safety hazards to the operation of trains, especially for freight cars. The huge longitudinal impact force generated during braking will directly damage the buffer device in the workshop. In addition, due to the limited propagation speed of the pressure wave of the compressed air pressure change in the train pipe when the brake is transmitted, this will lead to a longer idling time of the train, which in turn will lead to an extension of the braking distance. The extension of the braking distance will pose a greater safety hazard to trains, especially the operation of high-speed trains.

The function of the air brake is to stop the train safely by implementing regular braking and emergency braking according to the operating conditions of the train. The air brake system is an air brake system that receives electric signals to control the brakes, instead of realizing train brakes through decompression braking. The feature of the air brake system is that on the basis of realizing the brake function, the function of the brake system is configured in a modular manner, and the functions of the brake system are divided into brake control function, parking control function, air supply and Air spring control function, bow raising control function and sand spreading control function, etc. These functions almost include the functional requirements of all models for the braking system, and realize the air brake configuration required by different models through different combinations.
