汽車內襯板爛了一小塊需要換嗎？濟南奔馳汽車保養人員認為，如果輕微一點，建議修復一下，嚴重的話建議更換掉。葉子板是遮蓋車輪的車身外板，符合流體力學，減小風阻系數讓車行駛更加平穩。

A small piece of the car liner is worn out. Do you need to replace it? Jinan Benz car maintenance personnel think that if it is slight, it is recommended to repair it. If it is serious, it is recommended to replace it. The leaf plate is the body outer plate covering the wheels, which conforms to the fluid mechanics, and reduces the wind resistance coefficient to make the car run more smoothly.

1、前翼子板安裝在前輪處，須要保證前輪轉動及跳動時的大極限空間，因此設計者會根據選定的輪胎型號尺寸用“車輪跳動圖”來驗證翼子板的設計尺寸是否合適；

1. The front fender is installed at the front wheel, so it is necessary to ensure the large limit space when the front wheel rotates and jumps. Therefore, the designer will use the "wheel runout diagram" to verify whether the design size of the fender is appropriate according to the selected tire model size;

2、后翼子板沒有車輪轉動碰擦的問題，但是出于空氣動力學的考慮，后翼子板略顯拱形弧線并且向外凸出；

2. The rear fender does not have the problem of wheel rotation collision, but due to aerodynamic considerations, the rear fender is slightly arched and protrudes outward;

3、現在有些轎車的翼子板已與車身本體成為一個整體，生產時一氣呵成。但也有轎車的翼子板是獨立的，尤其是前翼子板，因為前翼子板的碰撞機會比較多，獨立裝配易于整件更換；

3. Now, the fender of some cars has been integrated with the body body, and the production is completed at one go. However, the fenders of some cars are independent, especially the front fenders. Because the front fenders have more collision opportunities, independent assembly is easy to replace the whole part;

4、其次，前葉子板可以使汽車行駛過程中，防止被車輪卷起的砂石、泥漿濺到車廂的底部，減輕對底盤的損傷及腐蝕；

4. Secondly, the front leaf plate can prevent the sand and mud rolled up by the wheels from splashing to the bottom of the car during driving, and reduce the damage and corrosion to the chassis;

5、因此，要求所使用材料具有耐氣候老化和良好的成型加工性。目前不少汽車車的前翼子板使用具有一定彈性的塑料材料制成，使其具有一定的緩沖性，更加安全。

5. Therefore, the materials used are required to be weather resistant and have good molding processability. At present, the front fender of many cars is made of plastic materials with certain elasticity, which makes it have a certain buffer and more safe.
