What is the purpose and content of detecting and diagnosing the technical condition of wheel alignment parameters?

The stability of driving in a straight line and the portability of handling can reduce the wear of tires and other components. The steering wheel, steering knuckle and front axle shall be installed in a certain relative position with the frame. This installation position relationship is called steering wheel positioning, also known as front wheel positioning. Steering wheel positioning includes four parameters: camber of front wheel, caster angle of kingpin, caster angle of kingpin and toe-in. 1, a set of two, made of natural rubber by vulcanization and high pressure synthesis, solid and practical, unique trapezoidal design, which can effectively reduce the impact force when parking, and the contact surface with the tire is about 55 degrees, with good anti-collision performance, wheel impact and hard object impact without damage. Strong buffering ability to protect buildings and vehicles from injury;

2. It has the advantages of sun protection, heat resistance, cold resistance, no cracking and no discoloration. Strong compression resistance, strong practicability and reasonable slope design. Suitable for large and small vehicles;

3, the yellow and black colors are eye-catching, which makes the wheel locator particularly eye-catching and plays a warning role; At night, it can reflect dazzling light, so that drivers can see at a glance and locate accurately;

4. Equipped with double mounting holes for fixing. Install wheel locators in the parking lot to avoid collisions between vehicles and between vehicles and other objects when parking. The installation is stable, and the vehicle will not move and deform when it collides, which effectively regulates the parking order. When installed, it is fixed on each parking space with explosion-proof screws. The specification of jacking screw is 14*70, with 24-diameter washers (hexagon socket head screws), one of which must be fixed with elastic thread, spike or bolt to ensure that the wheel locators of all parking spaces are in the same straight line. If the parking space is grass, the foundation must be laid before the car seat can be fixed.
