Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Suspension brackets>> Forward suspension bracket>> Corners of installation of wheels
Corners of installation of wheels considerably influence stability of the car, wear of tires and fuel consumption. Distinguish the following corners of installation of wheels.
Disorder — is an inclination of wheels in the vertical plane relatively the average line of the car (fig. 10.14) . 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 the difference of corners of disorder of wheels of the forward bridge more than 30’, withdraws the car aside at movement on a straight line. Adjustment of disorder can be made only in a junction of a rotary fist with the lower part of an amortization rack.
Convergence — a difference of distances between the wheels, their axes measured at height between edges ободьев (fig. 10.15) . 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 ahead of a wheel are at bigger distance from each other, than behind. On VW Passat the neutral convergence is established. At cars with the amplifier of a steering the convergence is regulated by only the right steering draft.
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 the vertical which has been carried out through a point of fastening of a wheel in the longitudinal direction of the car. At positive value of a corner self-return of a wheel to average situation after turn improves.
Corner of a longitudinal inclination of an axis of turn (fig. 10.16) . The axis concerning which there is a wheel turn, takes place in space so that its lower part is inclined forward. Such corner of a longitudinal inclination is called as positive.
Existence of a longitudinal inclination leads to creation of the stabilizing moments, aspiring to return operated wheels in the provision of rectilinear movement.
Conditions of check of corners of installation of wheels
Pressure in tires should correspond to norm.
The car should be established on an equal horizontal platform.
The car should not be loaded and should have the fuel tank filled half.
Before check of corners of installation of wheels shake a car body.
The steering should be serviceable and correctly adjusted.
In drafts of a steering should be absent люфт.
Should be absent люфт in a suspension bracket of wheels.
