The function of the driving device is to drive the rotation of the concrete storage tank. It consists of power take-off, cardan shaft, hydraulic pump, hydraulic motor, control valve, hydraulic oil tank and cooling device. For concrete mixers, the drive is still very important, so let's take a closer look.

1.万向旋转部分是经常发生故障的部分。应及时添加油脂，应经常检查磨损情况，并及时进行修理和更换。团队应该有一个备用的万向轴组件，以确保万一发生故障，它可以在数十分钟内恢复工作。

1. The universal rotating part is the part that often breaks down. Grease shall be added in time, wear condition shall be checked frequently, and repair and replacement shall be carried out in time. The team should have a spare cardan shaft assembly to ensure that in the event of a failure, it can return to work in dozens of minutes.

2.确保液压油清洁。混凝土搅拌车的工作环境恶劣，必须防止脏的水泥砂进入液压系统。应根据手册要求定期更换液压油。在检查期间发现液压油与水或沙子混合后，有必要立即停止机器以清洁液压系统并更换液压油。

2. Make sure the hydraulic oil is clean. The working environment of concrete mixer is bad, so it is necessary to prevent the dirty cement sand from entering the hydraulic system. The hydraulic oil should be changed regularly according to the manual. When it is found that the hydraulic oil is mixed with water or sand during the inspection, it is necessary to stop the machine immediately to clean the hydraulic system and replace the hydraulic oil.

3.确保液压油冷却装置有效。必须定期清洁液压油散热器，以防止散热器被水泥堵塞，检查散热器的电风扇是否正常运行，并防止液压油温度超过标准。只要清洁液压油，液压零件的故障就不会很多，但是不同制造商的使用寿命会有所不同。

3. Ensure that the hydraulic oil cooling device is effective. It is necessary to clean the hydraulic oil radiator regularly to prevent the radiator from being blocked by cement, check whether the electric fan of the radiator operates normally, and prevent the temperature of the hydraulic oil from exceeding the standard. As long as the hydraulic oil is cleaned, there will not be many failures of hydraulic parts, but the service life of different manufacturers will be different.

一般而言，如果驱动装置由于故障而停止工作，则混凝土储罐将无法正常旋转，这也将导致车辆中的混凝土报废，甚整个混凝土罐都将凝结在罐中，从而导致要报废的混凝土搅拌车。因此，驱动装置是否可靠是使用中必须注意的问题。

Generally speaking, if the driving device stops working due to failure, the concrete tank will not rotate normally, which will also lead to the scrapping of concrete in the vehicle, and even the whole concrete tank will condense in the tank, resulting in the scrapped concrete mixer. Therefore, whether the driving device is reliable or not is a problem that must be paid attention to in use.
