6、rt,供能元件部分 Supply Component Part,控制元件部分 Control Component Part,联合卡车制动系统工作原理详见下图（以42牵引车为例） 1. See the following drawing for the operating principle of C&C trucks brake system (take 64 tractor for example),从图中可以看出，整个制动气路大致可分为：行车制动、驻车制动、辅助制动及其余辅助用气等。下面将分别对这几种制动方式的工作原理作以详细介绍。 As seen from the drawing, the whole brake air circuit is roughly divided into: service brake, parking brake, supplemental brake, other auxiliary air and ect Next, the operating principles of these braking methods will be describ

It includes the front service brake circuit and the rear service brake circuit, which are independent. As shown by the bold lines in the drawing, the red represents the front service brake circuit, the green represents the rear service brake circ

9、rod is moved downward, the push rod seat of the brake valve 8 is pushed downward to eliminate the exhaust clearance, the exhaust valve of the brake valve is closed and the intake valve is opened. At this time, the controlled air flow from the rear axle air reservoir 4 passes through the upper chamber on the brake valve, flowing into the control port of the rear relay valve 10, the intake valve of the relay valve is opened by the air flow pressure, then the supply air flow from the rear axle air

10、reservoir passes through the inlet and the outlet of the relay valve, flowing into the rear axle service brake chamber 14, it achieves the service braking of the center rear axle. 与此同时，由前桥储气筒5过来的控制气流经制动总阀下腔流向前继动阀10的控制口，通过气流压力打开继动阀进气阀门，这时由后桥储气筒过来的供能气流便经继动阀进出气口，到前桥制动气室13，实现前桥行车制动。 At the same time ,the controlled air flow from the front axle air reservoir 5 passes through the lower chamber on the brake valve, flowing into the control port of the front relay valve 10, the intake valve of the relay valve is opened by the air flow pressure, then the supply air flow from the front axle air reservoir passes through the inlet and the outlet of the relay valve , flowing into the front axle brake chamber 13, achieving the service braking of the front axle. 对于牵引车，由制动总阀过来的行车制动控制气流同时流向挂车阀17控制口，控制挂车制动。 For the tractors, the service brake controlled air flow from the brake valve flows into the control port of the trailer valve 17 to control the trailer brake.,
