The smooth driving of concrete mixer can make it to the destination more safely. In the whole driving process, the driver needs to watch the road carefully, and must do a comprehensive inspection before driving. So what should we do if we run away?

1、由于前轮定位中转向主销的后倾角过小，前轮居中位置和稳固性差。转向主销必须有肯定的后倾角，以使主销轴线与地面的交点位于轮胎与地面打仗点之前。

1. Because the caster angle of steering kingpin is too small in front wheel alignment, the front wheel is in the middle position and the stability is poor. The steering kingpin must have a certain caster angle so that the intersection of the kingpin axis and the ground is before the point of contact between the tire and the ground.

当中科水泥自动搅拌车转向轮在行驶中偶然偶尔受外力作用偏转时，由于车轮与地面打仗处前轮有一个作用力，此力对主销轴线构成一个力矩，其偏向恰好与前轮偏转偏向相反，故可使前轮自动回居中位置，以包管小型水泥自动搅拌车稳固地沿直线行驶，因而称这个力矩为稳固力矩。

When the steering wheel of Zhongke concrete mixer is deflected occasionally under the action of external force, because there is a force on the front wheel at the place where the wheel is fighting with the ground, this force forms a moment on the kingpin axis, and its deflection is just opposite to the deflection of the front wheel. Therefore, the front wheel can automatically return to the center position, so as to ensure that the small concrete mixer can run stably in a straight line, so it is called this steering wheel The moment is the stable moment.

2、主销后倾角愈力，主销轴线延伸与地面的交点前轮与地面打仗点之间的距离愈大，稳固力矩也愈大；反之，稳固力矩愈小。因此，当汽车出现行驶不稳和跑偏时，应查抄调解主销的后倾角，设法使其连结划定值。小型水泥自动搅拌车两侧的轮胎和轮毂轴承紧度不划一，一侧的制动间隙过小，转向盘的游隙过大，也会引起汽车行驶跑偏，因此，还应过细对上部位举行查抄、调解或修。

2. The greater the caster angle is, the greater the distance between the intersection of the kingpin axis and the ground to the point of contact between the front wheel and the ground is, the greater the stabilizing torque is; on the contrary, the smaller the stabilizing torque is. Therefore, when the car is unstable and deviated, we should check and adjust the caster angle of the kingpin, and try to make it link to the designated value. Small concrete mixer on both sides of the tire and hub bearing tightness is not uniform, one side of the brake clearance is too small, the steering wheel clearance is too large, will also cause the car running deviation, therefore, should also be too careful to check the upper part, mediation or repair.

在行驶小型水泥自动搅拌车之前一定要做好检查，观察一下相应的位置是否正确，有无存在松动现象。平时也应该勤检查，及时进行修复。以上这些内容可以及时跑偏问题。

Before driving the small concrete mixer, it is necessary to check whether the corresponding position is correct and whether there is looseness. At ordinary times, they should also check frequently and repair in time. The above contents can solve the problem of deviation in time.
