（1）卡车刹车分泵是制动系统不可缺少的零件，它主要的作用是顶动刹车片，刹车片摩擦刹车鼓，使车速降低和静止。

（2）踩下刹车后总泵产生推力将液压油压到分泵，分泵内部的活塞受到液压力开始移动将刹车片推动。油刹车是由刹车总泵和刹车油储罐组成的。他们一头连着刹车踏板，一头连着刹车油管。刹车总泵内储有刹车油，并有出油口和进油口。当踩刹车时，出油口打开，进油口关闭。在泵体活塞的压力下，刹车油管被挤出油管向各刹车分泵流去作制动功能。当松开刹车板时。刹车总泵里的出油口会关闭，进油口打开，使刹车油从各刹车分泵回流到刹车总泵内，回到原始状态。

（3）卡车刹车分泵的分类
汽车刹车分气刹车和液油刹车。

●气刹车

气刹是由空气紧缩机(俗称 气泵),最少两个储气筒,刹车总泵一个,前轮的快放阀一个,后轮的继动阀一个.刹车分泵四个,调剂背四个,凸轮四个,刹车蹄八个和刹车古四个组成。

液油刹车

油刹车是由刹车总泵(液压制动泵)和刹车油储罐组成。

重型卡车用的是气刹车，一般的小车都是油刹车，所以汽车刹车总泵和刹车分泵都是液压制动泵。刹车分泵(液压制动泵)是制动系统不可缺少的零件

刹车时当你踩下刹车板时，刹车总泵就把刹车油通过管道送压到各刹车分泵。而刹车分泵有个连杆控制着刹车鞋或刹车皮。当刹车时，刹车油管内的刹车油就推动刹车分泵上的连杆，使刹车鞋加紧车轮上的法兰盘式把车轮停下来。汽车的刹车分泵的技术要求很高的,因为他直接影响人的生命.

4.卡车刹车分泵的原理
由气泵通过发动机带动,把空气紧缩到高压气体贮存在储气筒内.其中一个储气筒能过管路于刹车总泵相联.刹车总泵分上下两个气室,上气室控制后轮,下气室控制前轮.当驾驶员踩下刹车踏板时,上气首先打开,储气筒的高压气体传到继动阀.把继动阀的控制活塞推出,这时候另外一个储气筒的气体能过继动阀和两个后刹车分泵接通.刹车分泵的推杆向前推出,通过调剂背把凸轮转动一个角度,凸轮是偏心的,转动的同时把刹车蹄撑开与刹车古产生摩擦到达刹车的效果。
刹车总泵上室打开的同时下室也打开,高压气体进入快放阀,然后分给两个前轮的刹车分泵后一样。
当驾驶员松开刹车踏板时,上下气室关闭.前轮的快入阀和后轮的继动阀的活塞在弹簧的作用下回位.前后刹车分泵与的气室与大气相联,推杆回位,刹车结束。
一般都是后轮先刹车,前轮稍后,这样有益于驾驶员控制方向。

(1) The truck brake boosteris an indispensable part of the brake system, its main role is to push the brake pad, the brake pad friction brake drum, so that the speed is reduced and stationary.

(2) After stepping on the brake, the main pump produces a thrust to press the hydraulic oil to the sub-pump, and the piston inside the sub-pump begins to move under the liquid pressure to push the brake pad. The oil brake is composed of a brake master pump and a brake oil storage tank. They’re connected to the brake pedal at one end and the brake tubing at the other. Brake oil is stored in the brake master pump, and an oil outlet and an oil inlet are provided. When the brake is pressed, the oil outlet opens and the oil inlet closes. Under the pressure of the piston of the pump body, the brake oil pipe is extruded from the oil pipe to each brake pump to act as the brake function. When the brake plate is released. The oil outlet in the brake master pump will be closed, and the oil inlet will be opened, so that the brake oil from each brake branch pump back to the brake master pump, back to the original state.

(3) Classification of truck brake pump

Automobile brake is divided into air brake and hydraulic brake.

● Air brake

The air brake is composed of an air compressor (commonly known as an air pump), at least two air storage cylinders, a brake master pump, a quick release valve of the front wheel, and a relay valve of the rear wheel. The brake consists of four pump, four adjusting back, four CAM, eight brake shoes and four brake ancient.

Hydraulic brake

The oil brake is composed of a brake master pump (hydraulic brake pump) and a brake oil storage tank.

Heavy trucks use air brakes, and general cars are oil brakes, so the total brake pump and brake pump are hydraulic brake pumps. Brake pump (hydraulic brake pump) is an indispensable part of the brake system

When you step on the brake plate, the brake master pump sends the brake oil through the pipeline to the brake pump. The brake subpump has a connecting rod that controls the brake shoe or brake skin. When braking, the brake oil in the brake tubing pushes the connecting rod on the brake pump, so that the brake shoe tights the flange disc on the wheel to stop the wheel. The technical requirements of a car’s brake pump are very high, because he directly affects people’s lives.

4. Principle of truck brake chamber

Driven by the air pump through the engine, the air is compressed to high pressure gas stored in the reservoir. One of the reservoirs can be connected to the brake master pump through the pipeline. The main brake pump is divided into two chambers, the upper chamber controls the rear wheel, and the lower chamber controls the front wheel. When the driver presses the brake pedal, the upper air is first opened, and the high pressure gas from the reservoir is transmitted to the relay valve. Push out the control piston of the relay valve, and the gas from the other reservoir can be connected to the relay valve and the two rear brake subpumps. The push rod of the brake branch pump is pushed forward, and the CAM is rotated at an Angle by adjusting the back. The CAM is eccentric, and the brake shoe is stretched apart while rotating.

The upper chamber of the brake master pump is opened at the same time as the lower chamber is opened, and the high pressure gas enters the quick release valve, and then is distributed to the brake sub-pump of the two front wheels.

When the driver releases the brake pedal, the upper and lower air chambers close. The piston of the quick entry valve of the front wheel and the relay valve of the rear wheel return under the action of the spring. The front and rear brake pump and the air chamber are connected with the atmosphere, and the push rod returns to the position and the brake ends.

Generally, the rear wheel brakes first, and the front wheel brakes later, which is beneficial to the driver’s control of the direction.
