Abstract:
A braking system of a rail vehicle with a single-axle bogie, comprising a brake valve assembly (1). The brake valve assembly (1) comprises a brake valve (1-1). By means of a plurality of pipelines in a braking pipe system (2), the brake valve (1-1) is connected to a weighing valve (3), an air storage cylinder (4), and a basic braking device (5). The brake valve (1-1) is further connected to a main air pipeline (2-6) in the braking pipe system (2). The weighing valve (3) is mounted on a side face of a bogie (7) of a rail vehicle with a single-axle bogie. The basic braking device (5) comprises a brake cylinder (5-1). The brake cylinder (5-1) is connected to the brake valve (1-1). The brake cylinder (5-1) is connected to a brake shoe (5-8) such that a braking force directly acts on wheels by means of the brake shoe (5-8), thereby achieving the braking of the rail vehicle with a single-axle bogie. Further disclosed are a vehicle and a method. The braking system solves the problem in the prior art of a braking system of a rail vehicle with a single-axle bogie having braking defects, and has the beneficial effects of improving the braking effect of the rail vehicle with a single-axle bogie and ensuring the transportation capacity of the vehicle.
