The car turns to why the two wheels have no corner turn
Adjust the front of the direction of the machine around the two bars are not the same
Instantly turning the center, that is, the intersection of the front axle axis and the intersection of the two front wheels, is simply a circle with two different radii in the circle, that is, when the car is in motion. The wheel's trajectory is only when the inner wheel is deflected Angle is greater than the deflection angle of the outer wheel when the three axes can be submitted to a little car steering transmission mechanism generally use trapezoidal can guarantee the corner when the wheel deflection angle is greater than the outside wheel deflection angle
Because when the steering wheel outside the big round, the side of the wheel to take a small round. In order to avoid the additional resistance and excess wear of the car on the road when the car is turned, the steering system is required to ensure that all wheels are purely rolling when the car is turned. Obviously, this is only possible if the axes of all the wheels intersect at one point. In the figure, O is the steering center, we can see that the internal steering wheel deflection angle β should be greater than the outside steering wheel deflection angle α.
Because the car when the inside and outside the wheel through the distance is not the same (like running the same time running a circle of people running more than the distance) so in order to avoid uneven tire wear, the wheel angle is different
