13.11. Corners of installation of wheels of the car
THE GENERAL DATA

The main requirement to a design of a steering and a forward suspension bracket – car safety.

Corners of installation of wheels should provide the minimum resistance качению and to deterioration of tyres.

Convergence of wheels

The convergence of wheels (a turn of planes of rotation of wheels to the car centre) provides rotation of wheels in planes at action of longitudinal forces on car wheels. The convergence is necessary for indemnification of small backlashes and elasticity of details of a suspension bracket and a steering. Value of a convergence of wheels recommended by manufacturer corresponds to an exact parallel arrangement of planes of rotation of wheels at car movement. The deviation of a convergence of wheels from rating value leads to fast deterioration of tyres and increase in the expense of fuel. In process of deterioration of details of a suspension bracket and a steering correction towards increase in size of a convergence of wheels is required. The convergence of wheels is supervised and regulated in last turn.

Longitudinal inclination of an axis шкворня
The longitudinal inclination of an axis шкворня is understood as an inclination of an axis of turn of an operated ear which spends through the bottom spherical hinge and the top support of a spring rack of a forward suspension bracket. The corner of longitudinal bow of an axis is measured in a longitudinal plane of the car. For a positive inclination of an axis шкворня the corner corresponding to an arrangement of the top hinge of a rack of a suspension bracket behind the bottom spherical hinge is accepted. The axis angle of slope шкворня influences controllability of the car, but does not affect in any way deterioration of tyres. A procorf of springs of a forward suspension bracket or a car overload change a corner of a longitudinal inclination шкворня. At unequal corners of a longitudinal inclination of an axis шкворня the left and right wheels there is a tendency to lateral withdrawal of the car towards a wheel with a smaller positive angle of slope of an axis and шкворня. The longitudinal inclination of an axis шкворня is measured in degrees and is not subject to adjustment while in service the car.

Disorder of wheels


Disorder of wheels is understood as a deviation from a vertical of a plane of rotation of wheels. The disorder corner is measured in degrees and counted from a vertical. The size of a corner of disorder influences both controllability of the car, and on deterioration of tyres.

At too big positive disorder of wheels fast deterioration of an external part of a protector of the tyre is observed. Similarly, unduly больший the negative corner of disorder leads to fast deterioration of an internal part of a protector of the tyre. The disorder corner, as well as a longitudinal inclination of an axis шкворня, is not subject to adjustment while in service the car.

Cross-section inclination of an axis of turn of a wheel
The cross-section inclination of an axis of turn of a wheel characterises a deviation from a vertical of the axis passing through the bottom spherical hinge and the top support of a spring rack of a forward suspension bracket. The corner of a cross-section inclination of an axis of turn of a wheel is counted from a vertical.

The cross-section inclination of an axis of turn of a wheel promotes steady rectilinear movement of the car and provides stabilisation of operated wheels. The corner of a cross-section inclination of an axis of turn of a wheel is executed by the negative.

Corner between a plane of rotation and an axis of turn of a wheel

The corner between a plane of rotation and an axis of turn of a wheel is measured in degrees in a cross-section plane of the car, fig. the Cross-section inclination of an axis of turn of a wheel see. Value of this corner directly is not supervised, and defined by summation (taking into account algebraic signs) corners of disorder and a cross-section inclination of an axis of turn of a wheel.

Shoulder обката

The shoulder обката is equal to distance between trace of an axis of a rhinoceros of a wheel (passing through the bottom spherical hinge and the top support of a spring rack of a suspension bracket) on a basic plane and the centre of a contact print of the tyre. The size and a shoulder sign oбката are defined by a design of a suspension bracket and are not subject to the control and adjustment while in service the car.
