Corners of installation of wheels of the car Corners of installation of wheels of the car - the general information Corners of installation of wheels appreciably influence stability of the car, deterioration of tyres and the fuel expense. Values of corners are resulted in Specifications. Disorder is a corner between a plane of a wheel and a vertical. It can be positive if wheels are inclined outside or negative if wheels are inclined inside. The disorder corner, basically, influences uniformity of deterioration of tyres of forward wheels. If disorder of one wheel positive, and another negative the car will withdraw aside at movement on a straight line. The convergence is a projection of a corner between a plane of a wheel and a horizontal axis of the car on a horizontal plane. The positive convergence means that wheels are in front located is more close 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 on большем 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 turn of a rotary fist and a vertical, in a projection to a vertical a plane across the car. For the account of corners of disorder and a cross-section inclination of an axis of turn of a point of a contact of wheels with road settle down more close to an axis of a rotary fist. It supports so-called a shoulder обкатки, the driving is easier. 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 places in space so that its bottom 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 position after turn improves.
