自上料水泥攪拌車的運動過程主要包括發(fā)動機、液壓元件（油系、液壓馬達、減速機）以及攪拌筒等五部分裝置的運動。由發(fā)動機提供動力源，動力再通過油菜傳遞給液壓馬達，再通過減速機減速增大扭矩終實現(xiàn)攬拌筒的轉(zhuǎn)動。因控制終端為攪拌筒的轉(zhuǎn)速，而攪拌筒的速度由前面四部分裝置的運動決定，因此在運動分析過程將主要包括發(fā)動機、液壓元件等部分。

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.

發(fā)動機

engine

自動上料攪拌車一般使用柴油機作為發(fā)動機，系列柴油機是紅直列、活塞式、水冷、增壓才有發(fā)動機。紅徑，行程、虹心距、凈重功率覆蓋范圍為。

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.

系列柴油機通過采用高壓共軌燃油噴射技術(shù)，油耗低、可靠性高，該發(fā)動機上帶有為自動上料攪拌車上裝提供動力的動力輸出口，大輸出扭矩為大輸出功率。

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.

液壓元件

Hydraulic components

減速機釆用行星傳動齒輪箱，結(jié)構(gòu)緊湊，傳動效率高，運轉(zhuǎn)可靠易于維護保養(yǎng)。

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

攪拌速度控制：根據(jù)“發(fā)動機轉(zhuǎn)速油菜排量馬達排量減速機減速比耀體轉(zhuǎn)速，其中馬達排量、減速機減速比是常數(shù)，罐體轉(zhuǎn)速如果恒定為常數(shù)，則只要發(fā)動機轉(zhuǎn)速油粟排量為常數(shù)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.

電子恒速傳動方案是把液壓粟的控制形式改為電比例控制，液壓錄輸出流量與輸入電流成正比，通過調(diào)節(jié)比例閥的輸入電流，改變液壓粟斜盤角度，從而達到調(diào)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.

在一定發(fā)動機速度下，電比例液壓粟開度達到大，此時如希望攪拌罐的速度再上升則需要提高自動上料攪拌車底盤發(fā)動機速度。

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.
