Toe-in คืออะไร？ มีบทบาทอย่างไร？ อะไรคืออันตรายของ Toe-in ที่ไม่ถูกต้อง?
Toe-in หมายถึงมุมรวมระหว่างทิศทางไปข้างหน้าของตัวรถกับระนาบของล้อหน้า นอกจากนี้ยังหมายถึงระยะห่างระหว่างส่วนหน้าของล้อหน้ากับส่วนท้ายในทิศทาง Y ของรถ
The function of the front wheel toe-in is to make the wheels turn inward, which can offset the adverse effects caused by the front wheel camber, make the wheels roll in a straight line without lateral slippage, reduce tire wear, and also ensure that the direction can automatically return to normal after steering; In addition, due to the deformation of the hinge joint of the suspension system, the front wheels also have the tendency to turn outward, which also needs to be compensated by the front wheel toe-in.
When the toe-in of the car is not correct, it means that the toe-in is too large or too small, and the toe-in value of the car is too small, which will lead to the symptom that the direction can not automatically return to the right direction, and it is easy to float when driving at high speed; Excessive toe-in will cause excessive eccentric wear on the outside of the tire, and the steering wheel will be heavy when turning.
The so-called front wheel toe-in is the difference between the distance between the front edge of the two wheels and the distance between the rear edge of the two wheels. Generally speaking, the toe-in value is normal if it is between 0 and 8mm. The specific toe-in value is subject to the toe-in value specified by the automobile manufacturer. When the toe-in of the front wheel of the automobile is incorrect, it can be adjusted by changing the length of the tie rod.
However, it is generally not recommended to adjust it by yourself. It is better to drive the vehicle to a 4S store or a regular maintenance shop for adjustment; When the toe-in of the car is found to be incorrect, it must be adjusted in time, otherwise it will cause the car to deviate, especially in the case of sudden braking, and even cause the tail to swing; In addition, it will lead to abnormal wear of vehicles, shorten the service life of tires, and affect driving safety.
