輪胎指導

輪胎的正確使用和維護

1、保持正常的內壓。

2、定期更換輪胎的安裝位置。

3、按規定載重量裝載。輪胎超載，同樣會發生與空氣壓力不足時相同的損傷。載重時，還應保持每個輪胎的承載量基本相同。

4、不使用生鏽、變形或焊接過的鋼圈;受傷或鼓包胎必須更換。

5、避免急加速、緊急制動和急轉向。

6、不要在同軸上混裝規格不同和不同質量的輪胎。

7、使用與輪胎和輪圈配套的氣門嘴，並保證氣門嘴帽經常蓋着，以免泥沙進入。

8、通過有尖銳碎物之路面，須減速通過。

9、避免將車輛停放在有粗大、尖銳或鋒利石子的路面上。車輛不要停放在靠近或接觸有石油產品、酸類物質及其它影響橡膠變質的物料的地方。

10、避免貼近障礙物停車，以防胎側受到刮傷。
輪胎的作用

1、承受載荷；

2、產生驅動力與制動力；

3、緩衝和吸震；

4、改變汽車行駛方向。

正因為輪胎具有上述四大作用。因此，汽車才能在凹凸不平的路面上安全、自由、迅速、舒適的行駛，所以，輪胎在整個汽車零部件中才顯得特別的重要。
輪胎規格的表示方法

1、ISO國際質量認證表示方法

250 / 60 R 15 89 H

250-輪胎寬度(mm)、60-扁平比、R-子午線結構、15-輪胎內徑(in)、89-最大負荷、H-最高時速

2、DOT 美國表示方法

P 195 / 75 R 14 92 S

P-車型縮寫(客車PC)、195-輪胎寬度(mm)、75-扁平比、R-子午線結構、14-輪胎內徑(in)、92-最大負荷、S-最高時速

註：扁平比率：輪胎的高度和寬度之比，輪胎越扁性能越好，造價越高
輪胎結構分類

1、斜交輪胎：由多層帘布斜交而成。在中國被廣泛地應用到貨車和麵包車上。分別由胎面，胎體和胎緣組成。

2、子午線輪胎：1946年由法國米其林輪胎廠發明。其構造是帘布層內的線以輪胎中心成輻射狀排列，然後加上鋼帶層。它由胎面，帶束，胎體和胎緣組成。與斜交胎相比，其耐磨性能提高50%-100%，滾動阻力低30%，節省燃料8% -10%，提高牽引力10%-20%，提高側向力量50%-70%，抗刺破性能是斜交胎的5倍。但胎側耐抗擊性能不如斜交胎。輪胎中橡膠原材料所佔比例為49%。其餘橡膠添加物37%等。子午線輪胎已被廣泛使用，美國達90%，日本達70%以上。該種輪胎多用於轎車。
