Adjustment of corners of installation of wheels

For the best understanding of separate basic concepts at adjustment of wheels these illustrations are resulted.

For achievement of reliable controllability of the car forward wheels should stand under certain corners in a vertical and horizontal plane. That you could represent accurately to yourselves concept «a parity of angles of rotation of operated wheels», we result an explanation of some concepts:

Convergence: at Audi 80 forward wheels at rest in front stand is more close to each other a little, than behind. In these cases speak: a convergence "positive". The friction between a wheel and road wrings out the left wheel on the left, and right to the right. It is compensated by the forces arising in a forward drive, aspiring to compress forward wheels in front. At car occurrence in turn the positive convergence passes in a negative convergence (divergence) of wheels. It occurs thanks to a trapezoid arrangement of steering draughts: the internal wheel in turn bends more strongly the external. It is necessary, because on turn internal wheels describe narrower circle, than external.

Disorder: so name an easy inclination in forward wheels – at Audi 80 in a wheel niche above they are located is more close to each other, than below. In language of experts it is called as "negative disorder».

Cross-section inclination шкворня: it concerns disorder. The cross-section inclination шкворня is an insignificant inclination of a rotary axis round which at management of a wheel and all rack turns. Both rotary axes are above located is more close to each other, than below. Disorder and a cross-section inclination шкворня in addition prevent trembling of wheels and facilitate them проворачивание.

Longitudinal inclination шкворня back: it is necessary to understand inclined position of a rotary axis in a longitudinal direction of the car as it. It also helps to stabilise rectilinear movement by inertia and to prevent vibration of wheels. Besides, thanks to a longitudinal inclination there is a returning of a steering after turns.
