Abstract

The invention discloses an air brake system and a railway vehicle with the same. The air brake system comprises a service brake air cylinder, two foot brake valves; a first two-way one-way valve, thefirst two-way one-way valve comprises a first two-way one-way outlet and two first two-way one-way inlets, and the two first two-way one-way inlets are connected with air outlets of the two foot brakevalves respectively, the first two-way one-way valve is constructed to only allow one of the two first two-way one-way inlets to be communicated with the first two-way one-way outlet in a one-way mode; a first relay valve, a control port of the first relay valve is connected with the first two-way one-way outlet; and a brake air chamber, the brake air chamber is connected with an outlet of the first relay valve. According to the air braking system, the braking requirement of the rail vehicle with the double driving operation tables can be met, interlocking of the two foot braking valves is achieved, and safety of the rail vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air brakes, in particular to an air brake system and a rail vehicle with the same. Background technique [0002] In the related art, rail engineering construction vehicles are often equipped with front and rear driving consoles to facilitate the forward and backward movement of the vehicle. However, the existing braking system is not suitable for rail engineering construction vehicles with double driving consoles. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to propose an air brake system suitable for a rail engineering construction vehicle with a double driver's console. [0004] Another object of the invention is to propose a rail vehicle having the above-mentioned air brake system. [0005] The air brake system according to the embodiment of the first aspect...
