1 wheel alignment parameters
includes a rear caster
wheel alignment, the caster, camber and wheel toe four elements:
(1) Main after dumping the pin. Kingpin kingpin tilting means mounted on the front axle, an upper end slightly inclined rearward, so between the kingpin axis and the ground through the wheel center line to form a vertical angle in the vehicle longitudinal plane, called the main caster angle pin. Its main role is to maintain its stability when the vehicle is traveling straight, the steering wheel and allows the self-aligning.
tilt (2 kingpin. Kingpin tilting means mounted on the front axle, which is slightly inwardly inclined upper kingpin, then between the kingpin axis and the ground is formed in the vertical vehicle transverse plane of a clip angle, referred to the main caster angle. this angle is generally within not more than 80, the main role is to make the self-aligning steering wheel, the steering lightweight outer
(3) the front wheel camber. camber is after the wheel mounting means, its upper end is inclined outwardly, so the plane of rotation between the front wheels and the longitudinal vertical plane forming an angle, called the outer camber, its main role is to make light steering the wheels against the wheel Yi bearing, the outer bearing and to reduce the load of the wheel nut Yi, conducive to safe driving.
(4) front toe. front toe wheel mounting means, the distance from the front end of the two front wheels a rear end B is less than the distance a, which is the difference AB wheel toe-in. its role is to eliminate the adverse effect due to the traveling camber caused by the steering wheel linear rolling without dragging phenomenon of lateral sliding.
