From the structure of the car, the installation between the steering wheel (front wheel), the steering knuckle and the front axle of the car has a certain relative position. This installation with a certain relative position is called steering wheel positioning, also called front wheel positioning. . The front wheel positioning includes the main pin backward tilt (angle), the kingpin tilt (angle), the front wheel camber (angle) and the front wheel toe. For the two rear wheels, there is also a relative position to be installed between the rear axle and the rear wheel. Rear wheel alignment includes wheel camber (angle) and front wheel toe. In this way, the front wheel positioning and the rear wheel positioning are collectively referred to as four wheel positioning.
When the vehicle is shipped from the factory, the positioning angle is preset according to the design requirements. These positioning angles are used together to ensure the comfort and safety of the driving of the vehicle. However, since the vehicle is sold and driven for a period of time, these positioning angles may be caused by traffic accidents, road bumps and violent bumps (especially when bumping the road surface at high speed), chassis parts wear, and replacement of chassis parts. Changes due to reasons such as tire replacement. Once the positioning angle changes for any reason, it may cause symptoms such as abnormal tire wear, vehicle deviation, decreased safety, increased fuel consumption, accelerated wear of parts, sinking of the steering wheel, and drifting of the vehicle. Some symptoms make the car very dangerous when driving at high speeds.
Four wheel alignerThe purpose of the four-wheel alignment maintenance service is to diagnose and treat the above-mentioned discomfort of the vehicle by the positioning angle measurement. Generally, the new car should be positioned in four wheels after driving for 3 months. After every 10,000 kilometers, replace the tires or shock absorbers, and make four-wheel positioning in time after the collision. The correct positioning of the wheel can ensure flexible steering, comfortable ride, maintain straight-line driving, extend tire life and reduce vibration caused by road surface.
Most of the instruments currently used for wheel alignment detection are “four wheel alignersâ€. When detecting, the four wheel aligners first measure the current four wheel alignment parameters of the car, and then the computer automatically compares with the stored values ​​of the corresponding models. Positioning calculates the deviation value, and the maintenance personnel can correct the original condition according to the correction of the locator.
