Corners of installation of wheels of the car
Corners of installation of wheels of the car - the general informationCorners of installation of wheels considerably influence stability of the car, wear of tires and fuel consumption. Values of corners are given in Specifications.
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.
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.
