Indicator control in the instrument cluster is lit if the system is a failure, and does not distinguish the category of failure.
4.2. Wheels and tires General Alignment wheels The design of cars is the most important development of safe systems, steering and suspension. Each component must be strong enough to withstand and absorb the load limiting steering control, and front and rear suspension should operate geometrically with the body of the car. Steering system and suspension requires that the front wheels were self-returning, and to grip the rotating wheel and the road surface guarantees low driving force with the least effort and the greatest comfort. Full check of installation angles of the wheels should include measurement of convergence and collapse of the rear wheels. Adjustable mounting angles of the four wheels ensures that all wheels will roll strictly in one direction. When adjusted adjusting the angles of the wheels, saving fuel consumption and resource path reaches its maximum value, improves handling. Convergence Fig. 4.14. Scheme of convergence (wheels are installed inside forward)
Convergence is turning the wheels inside, opposite toe-wheels - wheels that turn outward from the center line. Convergence of the wheels provides parallel planes of rotation of the wheels.
Convergence is used to neutralize the small deviations of the wheel, taking place when the vehicle is moving forward. Installed the angle of convergence - the ability to install that angle at which the 0 ° between the planes of rotation of the front wheels and the center line of a moving car (no convergence). Incorrect toe or toe back wheel leads to premature tire wear and increase fuel consumption. Individual components of steering and suspension wear, depending on the mileage, an additional toe necessary to equalize wear. Always adjust the angle of convergence in the least. The angle of inclination of the axis of kingpin Angle of inclination of the axis of the hinge pivot is the highest point of the axis of the kingpin forward or backward from the vertical at the sight of the car on the side. Tilt back and forth is a positive - negative. The angle of inclination of the axis of kingpin affect the control of the direction of steering control, but does not affect tire wear. Weak (with a draft of) a spring or an overloaded vehicle affect the angle of inclination of the axis of kingpin. One wheel with a large positive slope of the axis of kingpin pulled to the center of the car. This causes a movement or tilt the vehicle towards the wheel with a smaller positive angle of inclination of the axis of kingpin. Angle is measured in degrees, but not regulated. Collapse The collapse of the wheels is the angle between the longitudinal axis of the wheels and the vertical to the plane of the road.
