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. 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.
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. 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.
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.
