Vehicle braking system and assembly method thereof and vehicle

The invention discloses a vehicle braking system and an assembly method thereof and a vehicle. The braking system comprises an air drying part, a regenerative gas storage part, an oil-water separationpart and a braking pipeline, wherein the oil-water separation part, the air drying part and the regenerative gas storage part are communicated through the braking pipeline in sequence, and the braking system further comprises an integrating part. The air drying part, the regenerative gas storage part and the oil-water separation part are installed on the integrating part. By arranging the integrating part, the air drying part, the regenerative gas storage part, the oil-water separation part and the braking pipeline are integrally assembled, the space occupation is low, the utilization rate ishigh, installation and later maintenance are more convenient, the production efficiency is improved, and the production cost is saved. 本发明公开了种车辆的制动系统及其装配方法、车辆，该制动系统包括空气干燥部、再生储气部、油水分离部和制动管路，所述油水分离部、所述空气干燥部和所述再生储气部由所述制动管路依次连通，所
