自上料水泥搅拌车的运动过程主要包括发动机、液压元件（油系、液压马达、减速机）以及搅拌筒等五部分装置的运动。由发动机提供动力源，动力再通过油菜传递给液压马达，再通过减速机减速增大扭矩终实现揽拌筒的转动。因控制终端为搅拌筒的转速，而搅拌筒的速度由前面四部分装置的运动决定，因此在运动分析过程将主要包括发动机、液压元件等部分。

The movement process of self loading cement mixer mainly includes the movement of five parts of devices, such as engine, hydraulic components (oil system, hydraulic motor, reducer) and mixing drum. The engine provides the power source, and then the power is transmitted to the hydraulic motor through the rape, and then the reducer slows down to increase the torque, and finally realizes the rotation of the mixing drum. Since the control terminal is the rotating speed of the mixing drum, and the speed of the mixing drum is determined by the motion of the first four parts of the device, the motion analysis process will mainly include the engine, hydraulic components and other parts.

发动机

engine

自动上料搅拌车一般使用柴油机作为发动机，系列柴油机是红直列、活塞式、水冷、增压才有发动机。红径，行程、虹心距、净重功率覆盖范围为。

Automatic loading mixer generally uses diesel engine as the engine, and the series diesel engine is a red in-line, piston type, water-cooled, supercharged engine. The coverage range of red diameter, stroke, rainbow center distance and net weight power is.

系列柴油机通过采用高压共轨燃油喷射技术，油耗低、可靠性高，该发动机上带有为自动上料搅拌车上装提供动力的动力输出口，大输出扭矩为大输出功率。

Series diesel engine adopts high-pressure common rail fuel injection technology, which has low fuel consumption and high reliability. The engine is equipped with a power output port to provide power for the loading of automatic feeding mixer truck, and the large output torque is large output power.

液压元件

Hydraulic components

减速机釆用行星传动齿轮箱，结构紧凑，传动效率高，运转可靠易于维护保养。

The reducer adopts planetary transmission gearbox, which has compact structure, high transmission efficiency, safe and reliable operation and easy maintenance.

搅拌速度控制：根据“发动机转速油菜排量马达排量减速机减速比耀体转速，其中马达排量、减速机减速比是常数，罐体转速如果恒定为常数，则只要发动机转速油粟排量为常数即可。

Mixing speed control: according to the "engine speed, rape displacement, motor displacement, reducer reduction ratio, body speed", in which the motor displacement and reducer reduction ratio are constant. If the tank speed is constant, as long as the engine speed and oil millet displacement are constant.

电子恒速传动方案是把液压粟的控制形式改为电比例控制，液压录输出流量与输入电流成正比，通过调节比例阀的输入电流，改变液压粟斜盘角度，从而达到调速目的。

The electronic constant speed transmission scheme is to change the control form of the hydraulic servo into electrical proportional control. The output flow of the hydraulic recorder is proportional to the input current. By adjusting the input current of the proportional valve, the angle of the hydraulic servo is changed, so as to achieve the purpose of speed regulation.

在一定发动机速度下，电比例液压粟开度达到大，此时如希望搅拌罐的速度再上升则需要提高自动上料搅拌车底盘发动机速度。

At a certain engine speed, the opening degree of the electro proportional hydraulic pressure reaches a large degree. At this time, if you want the speed of the mixing tank to rise again, you need to increase the engine speed of the chassis of the automatic feeding mixer truck.
