轿车的转向车轮、转向节和前轴三者之间的安装具有一定的相对位置,这种具有一定相对位置的安装叫做转向车轮定位,也称前轮定位。前轮定位包括主销后倾(角)、主销内倾(角)、前轮外倾(角)和前轮前束4个方面。这是对两个转向前轮而言,对两个后轮来说也同样存在与后轴之间安装的相对位置,称后轮定位。后轮定位包括车轮外倾(角)和逐个后轮前束。前轮定位和后轮定位总称四轮定位。通俗地说,四轮定位就是调整好固定轮胎的相关链接机构角度的一种操作,通过一系列的调整后,可以保证行车时车辆没有明显的跑偏情况。下面,我们来了解一下四轮定位的相关知识。
Car steering wheel, steering knuckle and the installation of the front axle between the three have a relative position, this has a relative position of the installation is called steering wheel positioning, also known as the front wheel positioning. Front wheel positioning including caster (caster), kingpin (angle), the front wheel camber (angle) and the front wheel beam four aspects. This is the two steering front wheel, the two rear wheels also exist with the relative position between the rear axle installed, said the rear wheel positioning. Rear wheel positioning includes wheel camber (corner) and rear by rear wheel bundle. Front wheel positioning and rear wheel positioning collectively four wheel positioning. Generally speaking, the four-wheel positioning is an operation that adjusts the perspective of the related link organization of the fixed tire. After a series of adjustments, it can ensure that the vehicle does not have obvious deviation when driving. Below, let’s look at the four wheel positioning related knowledge.
