FAQS on 300m input shaft

Q:什么是300M输入轴的核心应用场景?

A:300M输入轴主要用于高性能变速箱系统,例如赛车或重型机械。其高强度合金材质可承受极端扭矩和转速,常见于TH400等强化变速箱改装。

Q:TH400变速箱升级300M输入轴有哪些优势?

A:300M输入轴比原厂轴强度提升50%以上,能应对1000+马力的动力输出。其热处理工艺显著降低断裂风险,适合高负荷竞速场景。

Q:输入轴与输出轴在传动系统中的功能差异?

A:输入轴负责将发动机动力传递至变速箱,输出轴则将变速后的动力输送至传动系统。300M材质通常优先用于输入轴以应对更大的初始扭矩冲击。

Q:如何判断300M输入轴是否需要更换?

A:若出现变速箱异响、换挡迟滞或金属碎屑油液,可能提示输入轴磨损。建议每5万公里进行磁力探伤检测,竞技用途需缩短检测周期。

Q:300M输入轴与其他材质轴体有何性能差异?

A:相比4340钢材,300M的耐疲劳强度提升30%,抗拉强度达280ksi。其钼钒合金成分在高温下仍能保持结构稳定性,适合持续高负荷工况。

Q:安装TH400的300M输入轴需要哪些配套改造?

A:需同步升级强化离合器组和轴承支架。安装时必须使用专用夹具保证0.003英寸内同心度,并采用高温合成齿轮油进行润滑。

Q:赛车用300M输入轴有哪些特殊设计?

A:赛道版通常采用渐开线花键设计提升扭矩容量,表面氮化处理增强耐磨性。部分型号集成温度传感器接口,支持实时监测轴体工作状态。
