The invention discloses a double-section crawler air-cut brake system, and relates to the field of engineering vehicles. The system is composed of an air source storage mechanism assembly, an air pressure control mechanism assembly and a brake execution assembly. The air source storage mechanism assembly comprises an air storage bottle; a brake pedal of the air pressure control mechanism assemblyand an air inlet of a parking valve are connected with an air outlet of the air storage bottle through pipeline connectors, and a parking switch is connected with a parking valve through a wiring harness; the air inlet of a brake master cylinder of the brake execution assembly is connected with the brake pedal and the air outlet of the parking valve through pipeline connectors, and the air outletof the brake master cylinder is connected with the air inlet of a front-section vehicle relay valve and the air inlet of a rear-section vehicle relay valve through the pipeline connectors; and the airoutlets of the front-section vehicle relay valve and the rear-section vehicle relay valve are connected with a service brake air chamber of a front-section vehicle energy storage spring air chamber and a service brake air chamber of a rear-section vehicle energy storage spring air chamber through the pipeline connectors. Problems that an existing double-section crawler brake system is large in occupied space, difficult to arrange and adjust and poor in braking reliability and safety are solved.
一种双节履带车断气刹制动系统,涉及工程车辆领域。由气源储存机构总成、气压操控机构总成和制动执行总成组成;气源储存机构组成包括储气瓶;气压操控机构总成的刹车踏板和驻车阀进气口与储气瓶出气口通过管路接头连接,驻车开关和驻车阀通过线束连接;制动执行总成的刹车总泵进气口与刹车踏板和驻车阀出气口通过管路接头连接,刹车总泵出气口分别与前节车继动阀和后节车继动阀进气口通过管路接头连接,前节车继动阀和后节车继动阀出气口通过管路接头分别与前节车储能弹簧气室的行车制动气室和后节车储能弹簧气室的行车制动气室连接。解决了现有的双节履带车制动系统占用空间大,布置和调节困难,制动可靠性、安全性差的问题。
