9.24. Corners of installation of wheels
Corners of installation of wheels Corners of installation of wheels appreciably influence stability of the car, deterioration of tyres and the fuel expense. Distinguish following corners of installation of wheels: Disorder is an inclination of a wheel in a vertical plane concerning an average line of the car. 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. Convergence – lateral distance between wheels. 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 an inclination of a rotary fist and a vertical spent through a point of fastening of a wheel, looking in a 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 road settle down more close to an axis of a rotary fist. It supports so-called "a shoulder обкатки". The it is less "a shoulder обкатки", the driving is easier. Also blows from roughness of a covering are less transferred to a steering. Corner of a longitudinal inclination of an axis of turn. The axis concerning which there is a wheel turn takes places in space so that its bottom part is inclined 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. THAT is necessary to make check and adjustment of corners of installation of wheels at station in connection with complexity of the used equipment. |
