你們在停車的時候會把方向盤回正嗎？這個問題可能很多朋友壓根就沒注意過，今天自動上料攪拌機司機就來給我們講講攪拌機停車方向盤不回正的壞處吧。

Do you turn the steering wheel right when you park? This problem may not have been noticed by many friends. Today, the driver of the automatic feeding mixer will tell us about the disadvantages of the steering wheel of the mixer not returning.

攪拌機在打方向的時候會受到三種力的作用：

The mixer will be subjected to three kinds of forces when it hits the direction:

1.輪胎受力，車輛在直行時輪調是胎面受力，如果攪拌機在打方向時就會變成胎肩和一部分胎面受力；2.轉向拉桿的回正力，車輛轉向一般都會有一定的回正力，就是轉向拉桿會有一個與轉彎方向反向的拉力；3.懸掛系統支柱的受力偏移，如果我們在平整路面上原地打方向，這時車輛懸掛的左邊支柱受力比右邊大。

1. The tire is stressed. When the vehicle is running straight, the wheel adjustment is the stress on the tread. If the mixer is running in the direction, it will become the stress on the shoulder and part of the tread; 2. The return force of the steering link. Generally, the vehicle steering will have a certain return force, that is, the steering link will have a pull force opposite to the turning direction; 3. The force on the suspension system strut is offset. If we turn the direction on the flat road, the force on the left strut of the vehicle suspension is greater than that on the right.

方向盤不回正具體危害如下：

The specific hazards of steering wheel not returning are as follows:

對輪胎有損害：方向不回正對輪胎側壁會帶來一定的損傷，當方向盤沒有回正時，由于主銷傾角的存在和乘用車輪胎外傾的設計，輪胎并不完全是胎面著地，而是胎肩和一部分胎面受力，這種情況對輪胎的側壁壓力是比較大的，由于輪胎側壁相對較薄，長期下去就會加快輪胎側壁的老化變形，輪胎側壁老化變形后，很可能引起漏氣或爆胎的情況發生。

Damage to the tire: the steering wheel does not return to the right direction, which will cause certain damage to the sidewall. When the steering wheel does not return to the right direction, due to the kingpin inclination and the camber design of passenger car tires, the tire is not completely on the ground, but the shoulder and part of the tread are stressed. This situation has a relatively large pressure on the sidewall of the tire. Because the sidewall of the tire is relatively thin, the aging and deformation of the sidewall will be accelerated in the long run, After the tire sidewall is aged and deformed, it is likely to cause air leakage or tire burst.

對轉向機構有損害：停車時方向盤不回正，車輪會拽著轉向拉桿無法拉回，同時方向盤的齒輪和轉向拉桿的齒條也處于受力狀態，這種情況就好像拖拽著一個人的胳膊讓他睡覺，雖然當時不會有什么傷害，但久而久之就會造成這些零件加速老化或者變形，進而可能會導致車輛跑偏，還會對輪胎造成偏磨。

Damage to the steering mechanism: when the steering wheel does not return to the right position when parking, the wheels will drag the steering rod and cannot pull it back. At the same time, the gear of the steering wheel and the rack of the steering rod are also under stress. This situation is like dragging a person's arm to sleep. Although there is no harm at that time, it will cause accelerated aging or deformation of these parts over time, which may lead to vehicle deviation, It will also cause eccentric wear to tires.

對懸掛有損害：攪拌機的方向盤沒回正，車輪就會出現一個傾角，懸架系統就會向一個方向傾斜，懸架中的彈性支柱部分、橡膠封套還有懸架系統內的一些橡膠減震墊有一個應力，讓它們無法正常回位，造成懸架系統內的減震橡膠老化，懸架的擺臂和連桿的連接處會出現框量，框量越大磨損的就越厲害。

Damage to suspension: if the steering wheel of the mixer is not aligned, the wheels will have an inclination, and the suspension system will tilt in one direction. The elastic strut, rubber envelope and some rubber damping pads in the suspension system will have a stress, making them unable to return normally, causing aging of the damping rubber in the suspension system, and the connection between the swing arm and the connecting rod of the suspension will have a frame amount, The greater the amount of frame, the worse the wear.
