    汽车跑偏做四轮定位吗?
    2020-12-30 18:00:04

    每当车子发生跑偏的情况,相信很多人的反应就是应该去做四轮定位了,其实,汽车发生跑偏的情况有很多种,跑偏的原因有大有小,不一定是四轮定位可以解决的,下面,我们就来逐步了解这些问题。

    Whenever a car deviates, I believe that the first reaction of many people is to do four-wheel alignment. In fact, there are many kinds of car deviates. The reasons for the deviation vary from big to small. It is not necessarily that four-wheel alignment can solve these problems. Now, we will gradually solve these problems.

    下面进入正题,引起汽车跑偏的有哪儿些原因

    Now let's get to the point. What are the causes of car deviation

    车轮胎压

    Tire pressure

    当两侧轮胎的胎压相差较大时,车辆就极易发生跑偏现象。其实这个不难理解,在正常路面上行驶,当两侧轮胎的胎压相差较大时,它们接触地面的面积也是不同的,气压更低的轮胎摩擦力更大,所以在这种情况下,车辆会向出现低胎压轮胎的一侧跑偏。所以,当发现车辆有跑偏现象时,可以先检查一下两侧的胎压是否正常。

    When the tire pressure difference between the two sides is large, the vehicle is prone to run off. In fact, this is not difficult to understand. When driving on normal roads, when the tire pressures of the two sides are quite different, their contact area with the ground is also different. The tire with lower air pressure has greater friction. Therefore, in this case, the vehicle will deviate to the side with low tire pressure. Therefore, when it is found that the vehicle deviates, you can first check whether the tire pressure on both sides is normal.

    刹车系统

    Brake system

    当车轮两侧的刹车力度不一样时,刹车时车辆就会立刻发生跑偏现象。因为车辆在刹车时,两侧刹车力度不同,一侧的车轮刹车力度大于或小于另一侧的车轮刹车力度,就会产生“差速”(两侧的轮胎转动速度不同),就会发生车体偏向转动轮更慢的一侧。当汽车刹车时发现跑偏更严重时,应该立刻去检查刹车系统,一般都是由于刹车泵出现问题,刹车片不能正常回位导致跑偏。

    When the braking force on both sides of the wheel is different, the vehicle will immediately deviate when braking. Because when the vehicle is braking, the braking force on both sides is different, and the braking force of one side of the wheel is greater than or less than that of the other side, there will be "differential" (the rotation speed of the tires on both sides is different), and the car body will deviate to the side with slower rotation wheel. When the car brake found that the deviation is more serious, should immediately check the brake system, generally due to the brake pump problems, the brake pad can not return to normal, leading to deviation.

    四轮定位

    Four wheel positioning

    对于行驶一段时间的车辆来说,四轮定位数据的变化也会导致出现跑偏现象。特别是经常走坑洼路面的车辆,四轮定位的参数更容易发生变化,这个时候去正规的的维修店做四轮定位即可。注意,一定要去正规有保证的维修店做四轮定位,如果四轮定位做的不好,那么对车辆的影响还是很大的。

    For the vehicle driving for a period of time, the change of four-wheel alignment data will also lead to the phenomenon of deviation. Especially for vehicles that often walk on potholes, the parameters of four-wheel alignment are more likely to change. At this time, you can go to a regular maintenance shop to do four-wheel alignment. Note that you must go to a regular and guaranteed repair shop to do four-wheel alignment. If the four-wheel alignment is not done well, it will have a great impact on the vehicle.

            

    车身配重

    Body counterweight

    这个是更容易解决的。当车辆内放的物体较多,两侧的重量不平衡时,车辆也会出现跑偏现象。这里说的主要是经常拉重物的货车,特别要注意货物左右摆放均匀。如果重物经常靠一侧摆放,可能导致的问题 ,即使当时没有发生跑偏,经常左右摆放不均匀可能会导致轮胎左右磨损不平均,久而久之也会因为轮胎摩擦力不对称造成跑偏。

    This is the easiest one to solve. When there are many objects in the vehicle and the weight on both sides is unbalanced, the vehicle will also deviate. Here we are talking about trucks that often pull heavy loads. We should pay special attention to evenly placing the goods on the left and right. If the heavy objects are often placed on one side, it may cause problems. Even if there is no deviation at that time, the uneven placement on the left and right may lead to uneven wear on the left and right sides of the tires. Over time, it may also cause deviation due to the asymmetric friction of the tires.

    悬挂系统

    Suspension system

    悬挂的变形、松散,也会导致车辆发生跑偏现象。这可能是由于日常行驶造成的磨损和老化,如果是下摆臂等部件出现了变化或者是间隙过大,调整或者更换零件就可以解决了。

    The deformation and looseness of suspension will also lead to vehicle deviation. This may be due to wear and aging caused by daily driving. If the lower arm and other components change or the clearance is too large, it can be solved by adjusting or replacing parts.

    车体车架

    Car frame

    车架在受到严重的撞击后发生跑偏,这就麻烦了。因为发生事故造成的车体变形、车架受损等问题造成的跑偏,需要大面积更换零件甚至要进行车架校正才可能完全恢复。

    The frame deviates after being hit seriously, which is troublesome. Because of the car body deformation, frame damage and other problems caused by the accident, it is necessary to replace parts in a large area, or even to correct the frame before it can be completely recovered.

    简单的说,车辆跑偏时,我们可以从轮胎、刹车、配重、悬挂等方面入手检查,从而把跑偏问题给解决掉,而不是只想到四轮定位参数改变这一个问题,多了解汽车的状态,才能保养好自身的爱车。不忽略每一个部分,让爱车陪伴安全出行,也让自己安心省心。

    In short, when the vehicle deviates, we can start from the tire, brake, counterweight, suspension and other aspects to check, so as to solve the problem of deviation, instead of just thinking about the problem of changing the four-wheel alignment parameters. Only by knowing more about the state of the car can we maintain our car. Don't ignore every part, let your car accompany you to travel safely, and let you feel at ease.
