We all know that the appearance of small concrete mixer can be divided into different sizes, but how many people will notice the distance between the load-bearing tires under the concrete mixer? It can be said that the place where the wheelbase can't go, then it's decided that this place must not go, and the road which is narrower than the car frame doesn't have to go. After comparison, we find that if we choose a car according to the road conditions, it is important to look at the track width of the car rather than choose the external frame of the car. Next I'll tell you why.

　　首先，我們都知道車的框架是在輪胎之上的，而正因此與地面接觸的就是輪胎。那么也就是說判斷一個道路是否能過，主要就是看自己的輪距是否在這個道路寬度之內。從而我們也知道，一個自上料混凝土攪拌罐車的環境適應能力，不僅僅受到發動機的影響，還受到輪距的影響，那么我們自然而然知道小型自上料混凝土攪拌罐車輪距的選擇有就非常重要了。

　　First of all, we all know that the frame of the car is on the tire, and therefore the tire is in contact with the ground. That is to say, to judge whether a road can pass is mainly to see whether the track width is within the road width. Therefore, we also know that the adaptability of a concrete mixer to the environment is not only affected by the engine, but also by the wheelbase, so we naturally know that the selection of the wheelbase of a small concrete mixer is very important.

　　其次，輪距和車框架的搭配也是非常重要的。因為上面我們就說車框架是在輪胎之上的。那么合理的輪距承載多大的車框架，必須在合理承受范圍之內。正所謂量體裁衣，對車的衣服就是車框架。如果衣服裁的不合理，對于車不僅僅就是不好看那么簡單了，它的安全性也就大大下降。這也是為什么有的車型容易側翻的原因——車框架太大 ，輪距太小，過高車的穩定性便不言而喻。

　　Secondly, the matching of track width and frame is also very important. Because we said above that the car frame is on the tire. So the reasonable wheelbase bearing frame must be within the reasonable bearing range. The so-called tailor-made clothes are the frame of the car. If the clothes are not cut reasonably, it is not only not so simple for the car to be ugly, but also greatly reduces its safety. This is also the reason why some models are easy to roll over - it is self-evident that the frame of the car is too large, the track width is too small, and the center of gravity is too high.

　　后一點，汽車之間的輪距，也在一定程度上決定了這個車的性能。有人會覺得我這是在吹牛，不急下面我就給大家講解為什么會有這樣一層關系。汽車的各種功能都是由各個零部件來實現的，而這些汽車零部件的安裝都需要攪拌車提供空間。這些空間從哪來？大部分都是需要在汽車框架下面實現，而框架的高度要盡可能的低（提高穩定性），那么寬度就顯得尤為重要。這也就是小編所說輪距決定車的性能，更多的空間，裝更多的零部件從而實現更多的功能。

　　Later, the track width between cars also determines the performance of the car to a certain extent. Some people think that I'm bragging. I'll explain why there is such a relationship. All kinds of functions of the automobile are realized by various parts, and the installation of these parts needs the space provided by the mixer. Where do these spaces come from? Most of them need to be realized under the car frame, and the height of the frame should be as low as possible (to improve the stability), so the width is particularly important. That is to say, the track width determines the performance of the car, more space, more parts and components to achieve more functions.
