The angles of installation of forward wheels - the general information

Installation of forward wheels is understood as adjustment of their angular situation in relation to components of a suspension bracket and to a paving. Violation of angles of installation of forward wheels makes impact not only on effective management of the car, but also and on the speed of wear of tires. Only of parameters of angles of installation of forward wheels, subject to adjustment on cars of this brand are a corner of a longitudinal inclination of an axis of turn (выбег) and convergence of forward wheels.

Adjustment of angles of installation of forward wheels demands high precision therefore for its carrying out it will be reasonable to invite the qualified specialist having the necessary equipment. Authors of this manual made attempt to state in this Section the main idea of adjustment of angles of installation of forward wheels, for simplification of understanding by owners of cars of process for the purpose of simplification of negotiations with representatives of auto repair shop.

Convergence are called insignificant data of forward wheels to a car axis on its course forward. The purpose of adjustment of convergence is ensuring parallelism of forward wheels during turn. On cars with zero convergence the distance between forward edges of wheels equals to that between their rear edges. Usually the size of convergence makes about 2.5 mm. Adjustment of convergence is carried out by means of change of a tip of connecting steering draft. Violation of convergence is the reason of premature wear of tires owing to wheel slip on turns.

Convergence of forward wheels is always established by positive.

Vybeg name an inclination of an axis of turn of wheels concerning a vertical in the longitudinal plane of the car. At an axis inclination back выбег it is considered positive, at an inclination forward - negative. Adjustment of a vybeg is carried out by installation or removal of adjusting washers on a back part of the lower levers of a suspension bracket.

Выбег (an inclination of the top end of an axis of turn of a wheel forward from a vertical) influences characteristics of self-return of steering to a starting position; adjustment of a vybeg is not among procedures of routine maintenance of the car, however its correctness has to be checked every time change of a case of the forward bridge or levers of a forward suspension bracket is made.

Disorder (an inclination of the plane of forward wheels in relation to a vertical at a view of the car in front) is established at assembly of the car with a zero corner and is not subject to adjustment. If the corner of disorder of wheels deviates the established value, the faulty components which are a cause of infringement are subject to replacement.

Do not do at all attempts to make adjustment of a corner of disorder of forward wheels by heating or a bend of the bridge or other components of a suspension bracket.
