Zhongke self loading mixer is a kind of equipment combining the functions of concrete truck and concrete mixing station. It integrates concrete loading, metering, mixing, transportation and discharging. It can realize concrete transportation and on-site concrete mixer. The truck greatly improves production efficiency, reduces production time and cost, and has the characteristics of simple, fast and convenient operation. So do you know what causes the damage of the self feeding mixer clutch?

搅拌车的使用，提升了作业效率。每一种配件使用时间长了，都会出现一些问题。离合器位于发动机和变速箱之间的飞轮壳内，用螺钉将离合器总成固定在飞轮的后平面上，离合器的输出轴就是变速箱的输入轴。自上料搅拌车离合器损坏的原因介绍如下：

The use of mixer improves the operation efficiency. Every kind of accessory has been used for a long time, there will be some problems. The clutch is located in the flywheel housing between the engine and the transmission. The clutch assembly is fixed on the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the transmission. The reasons for the damage of the self feeding mixer clutch are as follows:

动力换挡变速器离合器接合时，液压油的压力克服弹簧力压紧摩擦片。随着液压油压力的升高，摩擦片与金属盘接触并逐渐压紧，使离合器将飞轮动力平稳地传递到变速器输人轴。每次换挡时，摩擦片都要与钢片发生摩擦，产生的热量由冷却液散发出去。

When the power shift transmission clutch is engaged, the pressure of the hydraulic oil overcomes the spring force to press the friction plate. With the increase of hydraulic oil pressure, the friction plate contacts with the metal plate and gradually compresses, so that the clutch smoothly transmits the flywheel power to the transmission input shaft. Every shift, friction plate and steel plate friction, heat generated by the coolant out.

当摩擦片及钢片变薄时，为了使它们充分接合就需要更多的液压油，自上料搅拌车发动机须进一步加速，摩擦片在钢片上的打滑时间也随之延长，由此产生的摩擦热量也会更多，促使液压油的温度增加，当达到足以改变变速器中密封件性能的温度时，变速器就会产生内泄。

When the friction plate and steel plate become thinner, in order to make them fully joint, more hydraulic oil is needed. The self feeding mixer engine must be further accelerated, and the sliding time of friction plate on the steel plate will also be extended. The resulting friction heat will also be more, which will increase the temperature of hydraulic oil. When the temperature reaches enough to change the performance of the seal in the transmission, the transmission will produce friction Internal discharge.

而内泄又从两个方面继续引起热量的增加：高压油经损坏的密封处泄漏，使油温继续升高；由于漏油，液压泵势必要输送更多的油液来保障接合离合器时所需的压力，使离合器充分地接合，这也要求发动机继续加速，使液压泵产生更大的流量。如此恶性循环，必将导致中科自上料搅拌车离合器过热或烧损，直完全失效。

The internal leakage continues to cause the increase of heat from two aspects: the leakage of high-pressure oil through the damaged seal causes the oil temperature to continue to rise; due to the leakage, the hydraulic pump needs to deliver more oil to ensure the pressure required to engage the clutch, so that the clutch can be fully engaged, which also requires the engine to continue to accelerate, so that the hydraulic pump can produce greater flow. Such a vicious circle will lead to overheating or burning of the clutch of Zhongke self feeding mixer until it is completely invalid.
