小型混凝土搅拌机轮胎的异常磨损往往存在，今天小编总结了几种常见的磨损情况及方法，希望能对广大搅拌机用户有所帮助。

Abnormal wear of small concrete mixer tires often exists. Today, Xiaobian summarized several common wear conditions and solutions, hoping to help the majority of mixer users.

对轮胎进行定点打磨

每次转动轮胎看是否停在同一位置，则车辆的动平衡出现错误，可能是由于制动鼓壁厚相差较大。然后拆下防尘盘，检查制动鼓内圈是否失圆（此时失圆不应大于0.5mm）。如果发现不圆，则拆下轮胎，固定制动鼓并检查内圈跳动。

Each time you turn the tire to see if it stops at the same position, the dynamic balance of the vehicle is wrong, which may be due to the large difference in the wall thickness of the brake drum. Then remove the dust disc and check whether the inner ring of the brake drum is out of round (at this time, the out of round shall not be greater than 0.5mm). If it is not round, remove the tire, fix the brake drum and check the inner ring runout.

如果两次相差较大，则属于钢圈问题，应更换钢圈。如果两次相差不大，应更换制动鼓或镗鼓。如果上述检查没有发现问题，检查悬架系统是否有问题。车辆正常装载时，悬架平衡臂应基本水平。

If there is a large difference between the two times, it is a steel ring problem, and the steel ring should be replaced. If the difference is not great, replace the brake drum or boring drum. If no problem is found in the above inspection, check the suspension system for any problem. When the vehicle is normally loaded, the suspension balance arm shall be basically horizontal.

由于搅拌机高度不同，悬挂系统与主车不匹配，轴重不均，制动时力小的车轴容易抱死。由于制动鼓在使用过程中有点失圆，在某一点抱死的概率比较高，造成定点磨损。在这种情况下，您应该与车辆工厂进行检查和调整。

Due to different mixer heights, the suspension system does not match the main vehicle, the axle load is uneven, and the axle with small braking force is easy to lock. Because the brake drum is a little out of round during use, the probability of locking at a certain point is relatively high, resulting in fixed-point wear. In this case, you should check and adjust with the vehicle factory.

锯齿状磨损

heel-and-toe wear 

指胎肩花纹的波浪状磨损。原因是车辆行驶时，轮胎的前进方向和行驶方向与车辆行驶方向有一定的夹角。如果轮胎想保持与车辆行驶方向相同的方向，就需要不断地修正方向。

It refers to wavy wear of shoulder pattern. The reason is that when the vehicle is driving, the forward direction and driving direction of the tire have a certain included angle with the driving direction of the vehicle. If the tire wants to maintain the same direction as the vehicle driving direction, it needs to constantly correct the direction.

如果这个问题发生在搅拌机的前轴上，说明车轴的两端和牵引销的中点不形成等腰三角形，即搅拌机的轴线与车轴轴线不垂直；如果前轴正常，后轴不正常，就是说后桥和前桥的轴距不相等，需要重新调整到2mm以内。

If this problem occurs on the front axle of the mixer, it means that the two ends of the axle and the midpoint of the traction pin do not form an isosceles triangle, that is, the axis of the mixer is not perpendicular to the axis of the axle; If the front axle is normal and the rear axle is abnormal, that is to say, the wheelbase of the rear axle and the front axle is not equal, and it needs to be readjusted to within 2mm.

注意检查时，小型混凝土搅拌机应停在相对平坦的场地上，同时保持车辆稳定，检查U型螺栓是否松动，拉杆橡胶套是否损坏。如果车辆在行驶中出现甩尾现象，牵引销的安装位置可能不在搅拌机的轴线上，需要到车辆厂进行检查和调整。

During inspection, the small concrete mixer shall be stopped on a relatively flat site, and the vehicle shall be kept stable. Check whether the U-bolts are loose and whether the rubber sleeve of the pull rod is damaged. If the vehicle flicks its tail during driving, the installation position of the traction pin may not be on the axis of the mixer, so it is necessary to go to the vehicle factory for inspection and adjustment.

另外，如果轮胎两侧损坏严重，说明车轴固定不好，即拉杆橡胶套磨损或U型螺栓松动。当车辆左转或右转时，轮胎两侧将分别接地。另外，轴承间隙过大，也会出现这种磨损。

In addition, if both sides of the tire are seriously damaged, it means that the axle is not fixed well, that is, the rubber sleeve of the pull rod is worn or the U-bolt is loose. When the vehicle turns left or right, both sides of the tire will be grounded respectively. In addition, the bearing clearance is too large, this kind of wear will also occur.

您可能会对搅拌机轮胎的磨损有一个大致的了解。其实，在车辆正常使用中经常检查，发现问题及时，很多耽误运营时间的情况是可以避免的。更多相关内容就来关注我们网站www.zishangliaojiaobanji.cn吧！
