What is the four-wheeled positioning?

Everyone often said, how is the four rounds of positioning? What can the four wheels can be adjusted? This article will make you have some basic understanding of the training of the car chassis.

First, the car wheel is divided into 4 angles. After the sales pin, the sales pin, the wheel outside the wheel, the front wheel angle

1. After the main pin

The main pin is an angle formed by the shock absorber and the vertical line of the overwheel center, (middle angle γ). This angle is very important. If your steering wheel can be returned to the end of the turn, it depends on this angle size. The higher the angle, the higher the stability of the vehicle (the steering wheel is not shake, very stable), the stronger the direction of the direction (turn over the steering wheel quickly), the disadvantage is that the steering wheel will become very sinking. The classic exaggeration of Harley Moto is a large sales tilt, but the car tends to reduce the perspective of the main pin to achieve more flexible steering.

The inner inclination angle is formed by the angle of suspension and ground vertical line. This angle is pre-preset in most original models, generally not adjusting themselves. The effect of this angle is basically consistent with the above-mentioned leading inclination, and the difference is that the rear inclination is more active at high speeds, and when the low speed is a steering wheel returns to the inner tilt angle.

This is our most familiar car inclination, there are many “low” style modified cars to change the wheel outside the wheel. Implementation. The outer angle of the wheel is formed by the angle of the wheel center line and the ground vertical line, which is also very important for car control.

The angle is called positive angle, which is used for large trucks that are in terms of off-road vehicles or large carriers. When carrying weight, wheels will be under gravity when carrying weight Pressure, form a larger contact area with the ground.

The angle is less than zero, called a negative tilt angle, the settings of the original vehicle factory are generally a negative tilt angle or the inclination is 0. but meThe common verses, such as F1, Super GT, etc., will see very exaggerated negative angles, because the wheel will expand outward due to the centrifugal force, and the larger negative angle can make the tire and the ground more Perfect fit, add friction to prevent slipping, thereby increasing the length of the bend.

The larger the angle of negative tilt angle, and also has a decrease in linear acceleration and brake performance, and is a tire partition that ordinary household cars. BMW has always been very concerned by the brand. On some models of the BMW, the angle of negative incidents is large to get better handling, but this price-free car tires are definitely can’t stand it. Therefore, when BMW is ordered to the tire manufacturer, it will specifically require a formulation of the inside and outside of the tires, (such as multiplier, Mi and Lin). So the BMW car owners must pay attention when replacing the tire, otherwise it will be partial.

The beam angle refers to the top of the vehicle, the wheel will present an eight (normal bundle angle), eight eight (Head angle) shape. It can be adjusted by the steering tensile rod, which is the most convenient adjustment in all angles. This angle is also the guinea that many riders appear in the steering wheel. Generally, the original vehicle will be preset as a positive angle or an angle of 0. This reduces the resistance of the wheel advancement, the degree of tire wear, and the increase of vehicle stability. The healing angle is common in the preset angle of the rear wheel, as well as there are applicable in some events.

In the F1 2020 event, the new technological DAS of Mercedes is through the continuous adjustment vehicle wheel angle, thereby achieving efficient management of tire temperatures, reducing the purpose of tire wear.

Do you know what you have learned? It is very difficult for the tuning of the wheel angle, even some metaphysics, everyone’s driving habits, the angle of need is different, so the car that meets yourself is the ultimate goal of many riders, now it seems Tuohai him used three months of tuning AE86 chassis hanging seemingly a very powerful thing!
