Corners of installation of forward wheels

GENERAL INFORMATION

Corners of installation of wheels


Corners of installation of wheels considerably influence stability of the car, wear of tires and fuel consumption. Distinguish the following corners of installation of wheels:

Disorder is an inclination of a wheel in the vertical plane relatively the average line of the car. It can be positive if wheels are inclined outside or negative if wheels are inclined inside. The disorder corner, generally influences uniformity of wear of tires of forward wheels. If disorder of one wheel positive, and another negative, withdraws the car aside at movement on a straight line.

Convergence – lateral distance between wheels. The positive convergence means that wheels are in front located more closely to each other, than behind at measurement at height of an average point of a wheel. The negative convergence means that wheels in front are at bigger distance from each other, than behind.

The cross-section inclination of an axis of turn of a wheel is a corner between an axis of an inclination of a rotary fist and the vertical which has been carried out through a point of fastening of a wheel, looking in the longitudinal direction of the car.

At the expense of corners of disorder and a cross-section inclination of an axis of turn of a point of a contact of wheels with the road settle down closer to an axis of a rotary fist. It supports so-called „a running in shoulder“, driving is easier than subjects. Also blows from roughness of a covering are less transferred to a steering.

Corner of a longitudinal inclination of an axis of turn of a wheel. The axis concerning which there is a wheel turn, takes place in space so that its lower part is directed forward. Such corner of a longitudinal inclination is called as positive. At positive value of a corner self-return of a wheel to average situation after turn improves.

Conditions of check of corners of installation of wheels

Check of corners of installation of the car demands existence of a viewing ditch or the special measuring lift. At carrying out measurement it is necessary to satisfy the following conditions:

– Pressure of air in tires corresponds to the set.
– Forward wheels are put directly.
– The car is not loaded, the fuel tank is completely filled.
– Suspension brackets of the car strongly прожаты.
– The steering is adjusted.
– Gaps in interface of steering drafts lie within the admissible
– Gaps in interface of a suspension bracket lie within the admissible
– Depth of drawing of a protector of tires of one axis is identical.

Values of corners of installation of wheels are given in Specifications.
