1. Chassis system: the main component of the mixer truck. The transportation function of the whole 8-square concrete mixer truck is realized by the chassis.

2、液压传动系统：将经取力器取出的发动机动力，转化为液压能（排量和压力），再经马达输出为机械能（转速和扭矩），为搅拌筒转动提供动力。

2. Hydraulic transmission system: the engine power taken out by the power take-off is converted into hydraulic energy (displacement and pressure), and then output into mechanical energy (speed and torque) through the motor to provide power for the rotation of the mixing drum.

3、搅拌罐体：搅拌筒是整个8方混凝土搅拌车的关键部件，是存储混凝土的容器，对防止混凝土固化、离析起着决定性的作用。罐体内部有叶片，主要起搅拌与导料的作用。

3. Mixing tank: the mixing drum is the key part of the whole 8-square concrete mixer truck, and is the container for storing concrete, which plays a decisive role in preventing concrete solidification and segregation. There are blades inside the tank body, which are mainly used for mixing and guiding materials.

4、出料系统：主要由主卸料槽、副卸料槽、锁紧杆等组成，副卸料槽起延长主卸料槽的长度的作用。

4. Discharge system: mainly composed of main discharge chute, auxiliary discharge chute, locking rod, etc. The auxiliary discharge chute plays the role of extending the length of main discharge chute.

5、清洗系统：清洗系统主要由压力水箱、水枪、水管、阀等组成。采用气压供水，主要作用是在装完料后冲洗料斗及出料完毕后冲洗拌筒、卸料槽，防止混凝土粘结。

5. Cleaning system: The cleaning system is mainly composed of pressure water tank, water gun, water pipe, valve, etc. The pneumatic water supply is mainly used to wash the hopper after loading and the mixing drum and discharge chute after discharging, so as to prevent concrete from binding.

6、副车架：搅拌车副车架是主要的承重部分，作业时的载荷几乎都是通过它来支撑再传递给底盘。副车架还起到缓解路面的颠簸、减速形成的冲击载荷的作用。整个副车架由主梁、前台支撑架、后台支撑架组成。

6. Sub-frame: The sub-frame of the mixer truck is the main load-bearing part, and the load during operation is almost supported by it and then transferred to the chassis. The subframe also plays a role in relieving the impact load caused by road bumps and deceleration. The whole sub-frame is composed of the main beam, front support frame and rear support frame.

7、操纵系统：操作系统由控制器、联动轴、软轴及连杆机构组成，主要控制搅拌筒的转速及旋转方向。

7. Operating system: The operating system is composed of a controller, a linkage shaft, a flexible shaft and a connecting rod mechanism, which mainly controls the speed and direction of rotation of the mixing drum.

8、托轮系统：搅拌罐后部与副车架连接的部位，主要起支撑滚筒体的作用。

8. Supporting roller system: the part connecting the rear of the mixing tank and the subframe, which mainly supports the roller body.

9、进料系统：主要由进料斗与支架组成，进料斗由于受冲击磨损较大，材料要求耐磨性好，支架主要起减轻冲击力的作用。

9. Feed system: mainly composed of feed hopper and support. The feed hopper is subject to heavy impact wear, and the material is required to have good wear resistance. The support is mainly used to reduce the impact force.

10、电路系统：主要指8方混凝土搅拌车的整个的电路，包括整车的尾灯，侧标志灯、示廊灯、冷却风扇电机等。

10. Circuit system: mainly refers to the entire circuit of the 8-square concrete mixer, including the tail light, side marker light, corridor light, cooling fan motor, etc. of the whole vehicle.
