乍一听觉得这四轮定位辣么高大上呢!很多人去做保养，可能技师会问你：四轮定位做吗?如果不懂的人可能会觉得这是保养中的一项，其实四轮定位是一种维修手段。那么四轮定位到底是怎么回事?需要多久做一次呢?今天商务车改装 http://www.sdamsa.org/ 小编和大家来探讨下!

 

At first listen to feel this four round of positioning hot it is a lot of people to do maintenance, may technicians will ask you: four wheel positioning do? If you do not understand the people may think that this is a maintenance, in fact, the four round positioning is a means of repair. So what is the four round of positioning in the end is how long it takes to do a business car modification and everyone to discuss the next!

 

NO.1 四轮定位是什么?

 

NO.1 four wheel positioning is what?

 

从字面上感觉，大家觉得也就是四个车轮的事儿。其实四轮定位指的是汽车车轮、减震、转向拉杆等底盘物件的安装之间一定的相对位置，这种相对位置的安装即称为四轮定位。

 

Literally, you think that's what's the four wheel. In fact, the four round of positioning refers to the car wheels, shock absorption, steering rod and other chassis objects of the installation of a certain relative position, this relative position of the installation is known as the four wheel positioning.

 

相对位置之间的距离、角度等即为四轮定位的参数，通过调整这些参数使汽车行驶达到最佳状态!经常调整的四轮定位参数有前轮前束、前轮外倾角、后轮前束、主销内倾角等，其中还有一些参数不可调。

 

The distance between relative position, angle and so on is four wheel positioning parameters, by adjusting these parameters to make the car to reach the optimal state. The four wheel alignment parameters are adjusted by the front wheel, the front wheel camber, the front beam, the main pin internal angle, and some of them are not adjustable.

 

NO.2 四轮定位操作需要啥?

四轮定位的操作需要借助四轮定位仪，包括一个四柱举升机加以配合。

NO.3 什么情况需要四轮定位

 

NO.3 what circumstances require the four round of positioning

 

最常见的情况就是车跑偏的时候。当你把方向摆正直线往前开的时候，车子自己会向左或向右跑偏，自己只能不停调整方向盘，稍不留神就会向左或向右跑出好几米，对安全驾驶有很大的影响。

 

The most common situation is the deviation of the car. When you to straighten straight ahead, my car will left or right deviation, yourself can not stop wheel to adjust the direction, a little inattentive will be to the left or right ran out of several meters, on safety driving has great influence.

 

另外就是轮胎偏磨，就是所谓“吃胎”，这种现象可能是长期车辆高速行驶或者年头长了致使轮胎偏磨很厉害。四轮定位不准还会导致汽车发飘、侧滑、转向不稳、悬挂系统零部件磨损异常等故障，严重影响行驶安全，所以对四轮定位有所重视是完全正确的。

 

In addition to the tire wear, is the so-called "eat tires", this phenomenon may be a long time of high speed of the vehicle or the cause of tire wear is very severe. Four wheel positioning will lead to car hair floating, sideslip, steering instability, suspension system parts and components of the abnormal wear failure, serious impact on traffic safety and so on four wheel positioning has attention is completely correct.

 

NO.4 四轮定位多久做一次

 

NO.4 four wheel positioning how long to do a

 

我们说，四轮定位仅仅是一种维修手段，通常情况下，如果车子没有什么问题是不需要做四轮定位的，所以四轮定位不需要像做保养一样定期做，而应该视情况而定。

 

We said that the four round of positioning is only a means of repair, usually, if the car is no problem is not necessary to do the four round, so the four wheel positioning without the need to do as regular maintenance, and should be considered as the case.

 

需要做四轮定位的情况如下：

 

Need to do the four wheel positioning as follows:

 

1、更换转向横拉杆等与调整四轮定位参数有关的底盘件时。

 

1, the replacement of the steering wheel, etc. with the adjustment of the four wheel alignment parameters related to chassis parts.

 

2、前后轮胎出现异常磨损时。

 

2, before and after the tire abnormal wear.

 

3、直线行驶时车辆向左或向右跑偏。

 

3, straight to the left or right deviation of vehicle.

 

4、驾驶过程中方向盘发飘、发抖或过重。

 

4, the process of driving up floating, shaking or overweight.

 

其实这都需要我们车主自己通过体验来决定是否该做四轮定位。如果您感觉不到明显的故障，但又总是怀疑车轮定位不准，也可以做个四轮定位检查一下，至于多久做一次的问题，四轮定位完全就不在“必须保养”这一项里面。

 

In fact, this is the need for our owners to decide whether to do the four round of positioning by the experience. If you do not feel the obvious failure, but always suspect that the wheel is not allowed to position, can also be a four round positioning check, as to how long to do a problem, the four round positioning is not in the need to maintain this one.
