23:35. Angles of installation of wheels
The angles of installation of wheels considerably influence stability of the car, wear of tires and fuel consumption. Distinguish the following angles of installation of wheels.
Disorder is an inclination of a wheel in the vertical plane of rather average line of the car. It can be positive if wheels are inclined outside and 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, then takes away the car aside at the movement on a straight line.
The corner of disorder of forward wheels is regulated after weakening of a forward hinged bolt of fastening of the lower lever of a forward suspension bracket due to change of provision of eccentric washers. Disorder of back wheels is not regulated.
The convergence is a side 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 convergence of forward wheels is regulated by a vvinchivaniye or a vyvinchivaniye of cross steering draft in spherical hinges therefore length of cross steering draft changes.
The convergence of back wheels is also regulated. Adjustment can be made, weakening and turning an internal hinged bolt of the directing lever of a back suspension bracket.
Check and adjustment of angles of installation of wheels need to be made at service station in connection with complexity of the used equipment.
The cross inclination of an axis of turn of a wheel is the corner between an axis of an inclination of a rotary fist and a vertical which is 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 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. Also blows from roughness of a covering are less transferred to steering.
Corner of a longitudinal inclination of an axis of turn. The axis concerning which there is a turn of a wheel 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 self-return of wheels to average situation after turn improves.
The corner of a longitudinal inclination of a forward wheel is regulated after easing and turn of a hinged bolt of back fastening of the lower lever of a forward suspension bracket. The longitudinal tilt angle of a back wheel is not regulated.
