Front wheels alignment. The tendency of the vehicle to keep straight ahead and the tendency to exit corners, i.e.. to return to the straight ahead direction, provides:. in. by giving the front wheels and steering knuckle pins a special setting. Looking at the steered wheels from the front of the car you can tell, that they are tilted in advance outwards from the vertical by angles a, called tilt angles. It is also noticeable at the same time, that the steering knuckle pins are inclined from the vertical at the angles P; corner 1 is called the steering spindle angle. When looking at the steering wheels from above, you can see their convergence towards the front. Means, that distance B should be smaller than distance A. When looking at the steering knuckle from the side, it is possible to see the advance of the gamut. The camber of the wheels by angle a is due to a downward deflection from the stub axle level. Such camber of the wheels is designed to eliminate play, which are present in the wheel hub bearings. In the absence of camber, the wheel tends to vibrate when rolling on uneven surfaces, i.e. the so-called. flutter, which is very harmful, due to the stability of the vehicle movement and the formation of additional stresses in the steering system. In addition, the inclination of the front wheels makes it easier to turn them when changing direction.
