- 它是变速箱输入轴（一轴）上的一档主动齿轮，负责将发动机动力传递到变速箱的一档传动比，实现重载起步、爬坡的大扭矩输出，是变速箱里承受载荷最大、最易磨损的核心部件之一。
法士特 8DS260 系列 8 档手动变速箱
- 防偏磨设计：宽胎面 + 优化花纹块接地压力，配合密集刀槽纹，有效缓解侧向力，减少不规则磨损，延长使用寿命
- 高耐磨配方：新配方与工艺，主打中长途高速工况，适合干线物流、快递运输等场景
- 低滚阻优化：胎冠轮廓优化，降低滚动阻力，兼顾燃油经济性
- 适用场景：导向轮 / 全轮位均可使用，适配标载快运、绿通、干线物流等中长途工况
- This is the 1st-speed driving gear on the transmission input shaft (primary shaft). It is responsible for transmitting engine power to the 1st gear ratio of the transmission, enabling high-torque output for heavy-load starting and climbing, making it one of the core components subject to the highest loads and most prone to wear in the gearbox.
