/What are the four wheel alignment machine parameters?
The front wheel camber means that the front wheel of the car is not completely perpendicular to the ground, but the front wheel has a certain angle of outward tilt with respect to the ground. The main pin tilt refers to the center of rotation of the steering wheel of the car – the main pin and the ground there is a certain angle between the main pin, and the king pin has a certain inclination with respect to the ground facing the car, so as to ensure that the car has a certain automatic returning ability when the car is impacted by the road surface.
After a certain mileage, the car wheel will go to the 4S shop for maintenance. Four wheel alignment can be said to be essential. So what is four-wheel alignment? What are the positioning parameters of automobile tires?
Four-wheel alignment, as the name suggests, is to position the four wheels of the car and re-constrain the position of the wheel within the range required by the manufacturer. Four-wheel positioning can effectively eliminate the phenomenon of automatic deviation of the car, generally four wheel alignment The important positioning wheel is the front two steering wheels, because for the car, the position of the steering wheel is correct or not.
Therefore, the positioning parameters of the wheel refer to the positioning parameters of the front wheels, which are the front wheel camber, the kingpin inward tilt, the kingpin back tilt and the front wheel toe. Front wheel camber means that the front wheel of the car is not completely perpendicular to the ground up, but the front wheel has a certain angle of outward tilt relative to the ground. The kingpin tilt refers to the center of rotation of the steering wheel of the car – there is a certain angle between the kingpin and the ground, and the kingpin has a face facing the car with respect to the ground.A certain inclination, this can ensure that the car has a certain automatic returning ability when the car is impacted by the road. The main pin backwards means that the main pin also has a certain inclination angle with respect to the rear of the car, which also makes the car the handling stability during driving is guaranteed. The last front wheel toe refers to the front wheel of the car and is not parallel forward, but the two front wheels have a certain tendency to close to the center line of the car, which can restrain the car.The wheel does not go to the sides due to the impact of the ground during the driving process.
It is very serious when the wheel is running in the driving process of the car. If it is wrong, the direction will be wrong, and the accident will be destroyed. Therefore, we must pay special attention. There are many reasons for the car to go wrong: tire pressure is not the same the degree of wear of the tread pattern is different, the design of the suspension system is problematic, or the suspension is injured deformed, displaced, etc., which will lead to deviation. If you don’t know if your car’s wheels are off-track, then there is one most common one. The detection method is to loosen the steering wheel and let the car drive slowly on the flat road for a few minutes while ensuring that you and others are safe. If you can completely walk straight, it means there is no deviation, if not Yes, you need a warranty and do four wheel alignment. In addition, the easiest way is that the person who drives the vehicle most has the right to speak, because the driver can really feel the wheel in the end.
