GENERAL INFORMATION

Corners of disorder, convergence of forward wheels and corner of a longitudinal inclination shkvornya

1. Corner of disorder of wheels

2. Corner of a longitudinal inclination shkvornya

3. Forward part of the car

4. Convergence of wheels (Y–X)


Adjustment of wheels is an adjustment of corners of installation of wheels in relation to a suspension bracket and the road. If wheels are not adjusted, it not only affects driving, but also increases the speed of wear of tires. For forward wheels the convergence, disorder and a corner of a longitudinal inclination shkvornya is usually regulated.

Disorder and convergence of wheels are subject to adjustment on release models since 1996. On release models till 1995 the unique adjustment is adjustment of a convergence of wheels. On back wheels it is possible to regulate only a convergence of wheels. Other corners of installation of wheels should be measured to reveal the bent or worn out suspension bracket elements.

Adjustment of convergence / disorder of wheels is very exact operation. High-quality adjustment of wheels requires use of difficult and expensive equipment. So, it is recommended to address to experts for adjustment of convergence/disorder of wheels. The general description of corners of installation of wheels to adumbrate to you about them is given below, and you could understand this question when address to auto repair shop better.

The convergence of wheels is a corner on which wheels are turned inside. The purpose of adjustment of a convergence of wheels is that wheels went in parallel. On the car at which the corner of a convergence of wheels is equal to zero, the distance between forward edges of wheels will be same, as distance between back edges of wheels. Really the size of a convergence of wheels usually makes some millimeters. On forward wheels, the corner of a convergence of wheels is regulated the provision of a tip of steering drafts. On back wheels, it is controlled by length of back cross drafts (N2). The wrong adjustment of a convergence of wheels will cause the wrong wear of tires, forcing them to rub about a road surface.

Disorder of wheels is a deviation of wheels from a vertical if to look in front of or behind the car. If the wheel is rejected outside in the top part, disorder positive (+). If the wheel is rejected in the top part inside, disorder negative (–). The size of a deviation is measured in degrees from a vertical and this value is called a corner of disorder of wheels. Depends on the size of this corner, what quantity of paths of a protector will be in contact about expensive, also, this corner it is necessary for compensation of changes in suspension bracket geometry at turns and at the movement on the rough road. Its adjustment is carried out with use of the special tools intended for adjustment of disorder of wheels.

The corner of a longitudinal inclination shkvornya is a deviation of an axis rotary shkvornya from a vertical. The deviation is called as a positive inclination shkvornya, and a deviation forward – negative back.
