13.26. Adjustment of corners of installation of wheels - the general description
Adjustment of wheels is an adjustment of corners of installation of wheels in relation to a suspension bracket and road. If wheels are not adjusted, it not only affects a driving, but also increases speed of deterioration of tyres. For forward wheels the convergence, disorder and a corner of a longitudinal inclination шкворня [is usually regulated the Fig.) See. Adjustment of a convergence/disorder of wheels is very exact operation. For qualitative adjustment of wheels use of the difficult and expensive equipment is necessary. So, it is recommended to address to experts for adjustment of a convergence/disorder of wheels. The general description of corners of installation of wheels is more low resulted to give you the general representation about them, and you could understand this question when address in a repair truck is 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 size of a convergence of wheels usually makes some millimetres. On forward wheels, the corner of a convergence of wheels is regulated position of a tip of steering draughts. On back wheels, it is supervised by length of back cross-section draughts (N2). Wrong adjustment of a convergence of wheels will cause the wrong
Deterioration of tyres, forcing them to rub about a road surface.
Disorder of wheels is a deviation of wheels from a vertical if to look in front 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 deviation size is measured in degrees from a vertical and this value is called a corner of disorder of wheels. On size of this corner depends, what quantity of paths of a protector will be in contact to road, also, this corner it is necessary for indemnification of changes in suspension bracket geometry at turns and at movement on rough road. Its adjustment is spent with use of the special tools intended for adjustment of disorder of wheels.
The corner of a longitudinal inclination шкворня is a deviation of an axis rotary шкворня from a vertical. The deviation is called as a positive inclination шкворня, and a deviation forward - negative back.
