The front steel plate of automatic concrete mixer consists of 9 parts. Many people report that one part and two parts of automatic concrete mixer are easy to break during use. What is the reason?

（1）过度使用紧急制动器。在上坡驾驶时，在下坡道路上使用紧急制动会导致前钢板断裂。由于制动力的作用，混凝土自动搅拌机的大部分负载质量都会被前板簧推动并承受，这很容易造成板簧的疲劳损坏。建议使用排气制动器以减少紧急制动。

(1) Excessive use of emergency brakes. When driving uphill, the use of emergency brake on downhill road will lead to the fracture of front steel plate. Because of the braking force, most of the load mass of the automatic concrete mixer will be pushed and borne by the front leaf spring, which is easy to cause the fatigue damage of the leaf spring. Exhaust brake is recommended to reduce emergency braking.

（2）前轮制动器调节太紧。如果后轮制动性能不佳或发生突然问题，请施加紧急制动以过度冲击破坏前片簧。

(2) Front wheel brake adjustment too tight. If the rear wheel braking performance is poor or there is a sudden problem, please apply emergency braking to damage the front leaf spring by excessive impact.

（3）路面不好，超载，超 速，前板簧受力过大，容易造成损坏。

(3) Bad road, overload, overspeed, front leaf spring stress is too large, easy to cause damage.

（4）前板簧经常长时间过载，弹性和刚度降低，疲劳受损。

(4) The front leaf spring is often overloaded for a long time, the elasticity and stiffness are reduced, and the fatigue is damaged.

（5）如果更换质量较差的板簧，则叶片的曲率不符合标准。钢材不好或热处理不好会导致应力不均和断裂。

(5) If the leaf spring with poor quality is replaced, the curvature of the blade does not meet the standard. Poor steel or heat treatment will lead to uneven stress and fracture.

为了防止混凝土自动搅拌车的前板簧的一块和二块自动加载，建议采用以下方法：

In order to prevent automatic loading of one and two front leaf springs of automatic concrete mixer, the following methods are recommended:

（1）检查并保持准时，以确保片簧润滑良好，并正确调节了车辆的制动器。

(1) Check and be punctual to ensure that the leaf springs are well lubricated and the brakes of the vehicle are properly adjusted.

（2）少用紧急制动，多用发动机排气制动，载荷均匀，无偏差，但不超载。

(2) Less use of emergency brake, more use of engine exhaust brake, uniform load, no deviation, but not overload.

（3）更换前钢板刀片时，一定使用优良钢板以确保弯曲度符合要求。使用山东弹簧厂和重庆弹簧厂生产的钢板弹簧。

(3) When replacing the blade of front steel plate, be sure to use excellent steel plate to ensure that the bending meets the requirements. The leaf springs produced by Shandong spring factory and Chongqing Spring Factory are used.
