The angles of installation of wheels (see tab. 13.2 ) considerably influence stability of the car, wear of tires and fuel consumption. Distinguish the following angles of installation of wheels:
Disorder is a corner between the plane of rotation and a vertical of a wheel. 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 the corner of disorder of one wheel positive, and another — negative, then can take away the car aside at the movement on a straight line.
Convergence — a difference of distances between onboard zakraina of the rims measured behind and ahead of wheels at the level of their centers. The positive convergence means that wheels are ahead located more closely to each other, than behind, at the level of their centers. The negative convergence means that wheels ahead are at bigger distance from each other, than behind.
The cross inclination of an axis of turn of a wheel is a corner between the axis of an inclination of a rotary fist and a vertical which is carried out through a point of fastening of a wheel in the longitudinal plane of the car.
At the expense of corners of disorder and a cross 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 a so-called "shoulder of a running in". The "running in shoulder" is less, the driving is easier. Besides, blows from roughnesses of a covering are less transferred to steering.
The corner of a longitudinal inclination of an axis of turn is a corner between the axis of an inclination of a rotary fist and a vertical which is carried out through a point of fastening of a wheel in the plane, a perpendicular longitudinal axis of the car. The axis concerning which the wheel turns is placed in space so that its lower part is inclined forward. Such corner of a longitudinal inclination is called positive. At positive value of a corner the best stability and stabilization of the operated wheels at the rectilinear movement is provided.
Check and adjustment of angles of installation of wheels need to be carried out at car repair shop in connection with complexity of the used equipment.
