目前，自动上料搅拌车轮侧减速器是一套附加的齿轮传动装置，通过减速和增加扭矩来满足整个传动系统的匹配需求。它安装在搅拌车的动力输出端，以减少齿轮箱的负荷。车轮减速器用于提高自动加料搅拌车的驱动力，以满足或校正整个传动系统驱动力的匹配。

At present, the automatic feeding mixing wheel side reducer is an additional gear transmission device, which can meet the matching requirements of the whole transmission system by reducing speed and increasing torque. It is installed at the power output end of the mixer to reduce the load of the gearbox. The wheel reducer is used to improve the driving force of the automatic feeding mixer to meet or correct the matching of the driving force of the whole transmission system.

发动机点火通过离合器、变速器和分动器将动力传递给前后轴的主减速器，然后从主减速器的输出端传递给轮侧减速器和车轮，驱动混凝土搅拌车。在这个过程中，轮侧减速器的工作原理是将主减速器传递的转速和扭矩在减速和扭矩增大后传递给车轮。

The engine ignition transmits the power to the main reducers of the front and rear axles through the clutch, transmission and transfer gears, and then transmits the power from the output end of the main reducers to the wheel side reducers and wheels to drive the concrete mixer. In this process, the working principle of the wheel side reducer is to transfer the speed and torque transmitted by the main reducer to the wheel after the deceleration and torque increase.

使车轮在地面附着力的反作用下能够产生更大的驱动力。

So that the wheel can produce greater driving force under the reaction of the ground adhesion.

如何自动上料搅拌车混凝土搅拌车液压表气压不足的问题，如果生产的混凝土搅拌车液压系统出现问题怎么办，当搅拌车液压系统气压不足或根本没有气压时，我们可以依次从以下几个方面进行调查。

How to solve the problem of insufficient air pressure in the hydraulic meter of the automatic feeding mixer, what to do if there is a problem in the hydraulic system of the produced concrete mixer, when the air pressure in the hydraulic system of the mixer is insufficient or there is no air pressure at all, we can investigate from the following aspects in turn.

1、检查混凝土搅拌车液压泵是否能输出液压油。如果是新液压泵，没有液压油输出，可能是泵体有铸造缺陷(缩孔、砂眼等)。)，使吸油室和油压室相互连通，从而失去油压能力，泵体应由制造商及时更换。如果不是新液压泵，也没有液压油输出，则可能是泵的转向错误，零件严重磨损或损坏，应及时更换。

1. Check whether the hydraulic pump of concrete mixer can output hydraulic oil. If it is a new hydraulic pump and there is no hydraulic oil output, the pump body may have casting defects (shrinkage cavity, sand hole, etc.). ）The pump body should be replaced by the manufacturer in time. If it is not a new hydraulic pump, and there is no hydraulic oil output, it may be the wrong steering of the pump, and the parts are seriously worn or damaged, which should be replaced in time.

2.如果混凝土搅拌车液压泵有油输出，检查溢流阀是否正常工作。如果不正常，可能是压力油路中的某个阀门被污垢或其他原因卡住，处于回油位置，导致压力油路与溢流管路短路，或者管接头松动，或者压力油路中的某些阀门泄漏严重，或者液压缸和液压马达的密封损坏，导致严重泄漏。方法是拆卸相关阀门进行清洗，检查密封间隙和各种密封装置的尺寸，如有损坏，更换密封装置。

2. If the hydraulic pump of concrete mixer has oil output, check whether the relief valve works normally. If it is abnormal, it may be that a valve in the pressure oil circuit is stuck by dirt or other reasons and is in the oil return position, resulting in a short circuit between the pressure oil circuit and the overflow pipeline, or the pipe joint is loose, or some valves in the pressure oil circuit leak seriously, or the seal of the hydraulic cylinder and the hydraulic Mada is damaged, resulting in serious leakage. The elimination method is to dismantle the relevant valves for cleaning, check the sealing clearance and the size of various sealing devices, and replace the sealing device in case of damage.

3.如果水泥混凝土搅拌车液压泵的输出流量随着压力的增加而显著下降，且压力达不到规定值，则是由于液压泵磨损后间隙增大。方法是测量液压泵的容积效率，以确定该泵是否可以继续使用。磨损严重的零件应该修理或更换。

3. If the output flow of hydraulic pump of cement concrete mixer truck decreases significantly with the increase of pressure, and the pressure does not reach the specified value, it is due to the increase of clearance after the hydraulic pump is worn. The elimination method is to measure the volumetric efficiency of the hydraulic pump to determine whether the pump can continue to be used. Worn parts should be repaired or replaced.

4.混凝土搅拌车的液压系统可以建立正常压力，而一些管道或液压缸(或液压马达)没有压力，这可能是由于管道、小孔或节流阀、换向阀等部件堵塞造成的。此时，应逐步检查压力和有无油，找出原因并排除。

4. The hydraulic system of concrete mixer can establish normal pressure, while some pipes or hydraulic cylinders (or hydraulic motors) have no pressure, which may be caused by blockage of pipes, small holes or throttle valves, directional valves and other parts. At this time, the pressure and oil should be checked step by step to find out the cause and eliminate it.
