The corners of the front axle
The angles of the wheels greatly affect the stability of the car, tire wear and fuel consumption. There are the following wheel alignment: Camber - an inclination of the wheel in a vertical plane about the center line of the vehicle. It can be positive if the wheels are inclined outwardly or negative if the wheels are inclined inwardly. Camber substantially affect the uniformity of tire wear of the front wheels. If one wheel camber is positive and the other negative, then the car will withdraw aside at movement in a straight line. Convergence - lateral distance between the wheels. Positive convergence means that the front wheels are located closer together than the rear adjustment when measured at the middle point of the wheel. A negative convergence means that the front wheels are at a greater distance from each other than behind. Cross caster wheel - is the angle between the axis tilt steering knuckle and the vertical passing through the point of fastening of a wheel, looking in the longitudinal direction of the vehicle. Due to the collapse of the angles and transverse axis tilt rotation point of contact with the road wheels are located closer to the axis of the steering knuckle. This is supported by the so-called "shoulder running." The smaller "arm running", the easier driving. Also blows from roughness of the coating is less transmitted to the steering. The angle of inclination of the longitudinal axis of rotation. The axis about which the wheel rotates is placed in the space so that its lower part is inclined forward. Such corner of a longitudinal inclination is called positive. When positive self-resetting wheel angle to the center position after turning improves. Check and adjust the wheel alignment should be performed at station due to the complexity of the equipment used.
