Whether it is a large concrete mixer or a conventional car, it is composed of many accessories. The configurations of some models of different brands seem similar, but the prices differ greatly. Because most people only look at the configurations of some large parts when buying a car, many people want to know about the differential and differential lock. A large concrete mixer will give you a brief introduction. There is only one word difference between the names of these two accessories, but the function is opposite.

差速器：差速器是一种可以让左右驱动轮实现不同转速转动的机构，主要由左右半轴齿轮、两个行星齿轮及齿轮架组成的，当车辆转弯的时候，车轮内外两侧的转速是不一样的，如果没有差速器，车辆转弯就不稳定，轮胎就会滑动，轮胎磨损就会加剧，有了差速器就不一样，它能让轮胎转速产生差异，转弯的时候就可以使左右车轮进行合理的扭矩分配，从而达到合理的转弯效果。大型混凝土搅拌机

Differential: the differential is a mechanism that enables the left and right drive wheels to rotate at different speeds. It is mainly composed of left and right half axle gears, two planetary gears and gear carrier. When the vehicle turns, the speeds on the inner and outer sides of the wheel are different. If there is no differential, the vehicle will be unstable when turning, the tires will slide and the tire wear will increase, The differential is different. It can make the tire speed different. When turning, it can make the left and right wheels carry out reasonable torque distribution, so as to achieve reasonable turning effect. Large concrete mixer

差速锁：差速锁是安装在差速器上的一种锁止机构，当车辆陷入泥泞的道路时，其中一个驱动轮打滑，此时差速器与半轴锁紧成一体，使差速器失去差速的作用，这样就能将全部扭矩转移到另一侧的驱动轮上，车辆就很容易摆脱困境，一般大的车型上使用较多，比如搅拌车、随车吊等等。大型混凝土搅拌机，一般情况下很多车辆都有差速器，但不是每款车都有差速锁，对于一些工程类的车型来说，这种配置还是很有必要的。

Differential lock: differential lock is a locking mechanism installed on the differential. When the vehicle falls into a muddy road, one of the driving wheels slips. At this time, the differential is locked with the half axle, so that the differential loses the function of differential speed. In this way, all torque can be transferred to the driving wheel on the other side, and the vehicle can easily get out of trouble. It is often used on large models, Such as mixer truck, truck mounted crane, etc. For large concrete mixers, generally, many vehicles have differential, but not every vehicle has differential lock. This configuration is still necessary for some engineering models.

生产完成后需要人员定期进入清理，此是比较危险的作业，常出现工伤事故，进入主机内一定要先拉闸，确定停电后再作业，其次关重要的一点，主机门上的限位开关不得短接，另外在主机内清理时容易磕碰、滑倒，注意内部通风。

After the completion of production, personnel are required to enter and clean regularly. This is a dangerous operation. Industrial accidents often occur. When entering the host, you must first turn off the switch and confirm the power failure before operation. Secondly, it is very important that the limit switch on the host door shall not be short circuited. In addition, it is easy to bump and slip during cleaning in the host. Pay attention to internal ventilation.
