CarDetection linesFour-wheel positioning is performed to maintain the reliability of the vehicle and to reduceCarWear and tear of tires and steering parts during the march.

Front wheel positioning includes the rear inclination of the main pin and the inner inclination of the main pin.

Looking at the wheel from the side, turning to the main pin (the center of rotation when the wheel turns) is dumped backwards, called the rear inclination of the main pin. After setting the rear inclination of the main pin, the distance between the connection address of the main pin centerline and the ground projection point in the center of the wheel (called the main pin longitudinal tilt distance, the same principle as the back of the bicycle's front-wheel fork beam), so that the grounding site of the wheel is located to the back end of the main pin extension line, the Make the direction of the wheel naturally oriented towards the direction of travel. Set a large main pin after the inclination can improve the linear travel function, together the main pin tilt shift distance also increases. The tilt shift distance of the main pin is too large, which will make the steering disk heavy, and increase the front and rear fluctuation of the wheel due to road interference.

When looking at the tyre from the front and rear direction of the car, the main pin is tilted to the inside of the body, which is called the inner inclination of the main pin. When the wheel reverses at the center of the main pin, the lowest point of the wheel will fall below the pavement, but in fact the lower edge of the wheel is unlikely to fall below the pavement, but will turn to the wheel along with the entireCarLift up a corresponding height on the front, soCarIts own gravity has the effect of returning the steering wheel to its original middle azimuth, so the steering wheel reset is easy.
