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, supp lemental brake, other auxiliary air and ect.. Next, the operating principles of these braking methods will be desc ribed in detail. 5

当需要车辆减速或遇红绿灯等其余路况需要临时停车时，驾驶员踩下制动踏板，顶杆下移，推动制动总阀8的顶杆座下移 ，消除排气间隙，制动总阀排气阀门关闭，进气阀门被打开，这时由后桥储气筒4过来的控制气流经制动总阀上腔流向后 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，到后 桥行车气室14，从而实现中后桥的行车制动；
a.行车制动：Service Brake: 联合卡车行车制动采用双回路气压制动系统。即前行车制动回路和后行车制动回路，二者彼此独立。见下图线条加粗 部分，其中红色代表前行车制动回路，绿色代表后行车制动回路。 The C&C truck service brake uses the double-circuit pneumatic brake system. It includes the front service b rake circuit and the rear service brake circuit, which are independent. As shown by the bold lines in the dra wing, the red represents the front service brake circuit, the green represents the rear service brake circuit.

一、概述 Chapter 1 Overview
1、制动系的功用：Functions of Brake System: ①使行驶的汽车减速或停车； ① Decelerate or stop the running vehicle; ②使下坡行驶的汽车车速保持稳定； ② Keep the speed stable when the vehicle is driven on the downhill; ③使已停驶的汽车在原地（包括在斜坡上）驻留不动。 ③ Leave the stopped vehicle in original location (including on the slope). 2、制动系的类型： Types of Brake System: ①行车制动：通过操纵制动踏板实现 ① Service brake: it is achieved by operating the brake pedal ②驻车制动：通过操纵驻车制动手柄实现 ② Parking brake: it is achieved by operating the parking brake handle ③应急制动：与驻车制动相结合，通过操纵驻车制动手柄实现 ③ Emergency brake: Combining with the parking brake, it is achieved by operating the parking brake handle ④辅助制动：通过操纵驾驶室内辅助制动按钮实现 ④ Supplemental brake: it is achieved by operating the supplemental brake button in the cab 3、制动系的组成： Components of Brake System: ①供能装置：如空压机、储气筒等 ① Supply device: such as air compressor, air reservoir ②控制装置：如制动踏板、手阀等 ② Control device: such as brake pedal, parking brake ③传能装置：如各控制阀及管路元件等 ③ Transmission device: such as various control valves and pipe components ④执行装置：如制动器等 ④ Execution device: such as brake

When it is necessary to decelerate the vehicle or stop it temporarily as encountering the traffic light or other ro ad conditions, the driver depresses the brake pedal, the push 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 cl osed and the intake valve is opened. At this time, the controlled air flow from the rear axle air reservoir 4 passe s through the upper chamber on the brake valve, flowing into the control port of the rear relay valve 10, the inta ke valve of the relay valve is opened by the air flow pressure, then the supply air flow from the rear axle air rese rvoir 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 inl et 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 trail er valve 17 to control the trailer brake.
