The invention discloses a commercial vehicle gearbox matching method. The method comprises the following steps: safety coefficient matching: the safety coefficient=the allowable maximum torque of a gearbox/the maximum torque of an engine, wherein the safety coefficient of a standard vehicle model needs to reach 1-1.2, and the safety coefficient of a heavy vehicle model needs to reach 1.2-1.4; thetorque range, capable of being matched with the engine to be matched, of the gearbox is preliminarily confirmed through safety coefficient matching; matching the interface type of the gearbox; matching of a dimension chain to determine the dimension chain required for realizing stable power output; and manipulation matching: specifically, the comfort of a gear selecting and shifting control mechanism of the matched gearbox and the clutch control comfort are determined. By means of the method, when the gearbox is matched with engines of various different types, the engine and the gearbox can achieve the optimal matching performance.

    本发明公开了一种商用车变速箱匹配方法,包括以下步骤:安全系数匹配:安全系数=变速箱允许最大扭矩/发动机最大扭矩,标载版车型的安全系数需要达到:1‑1.2,重载版车型的安全系数需要达到:1.2‑1.4,通过安全系数匹配,初步确认所要匹配的发动机所能匹配的变速箱的扭矩范围;变速箱接口类型的匹配;配合尺寸链的匹配,以确定实现动力稳定输出所要求的尺寸链;操纵匹配:以确定匹配的变速箱的选换档操纵机构的舒适性和离合操纵舒适性,通过本发明的方法能够使变速箱在匹配各种不同型号的发动机时,发动机和变速箱能达到最优的匹配性能。
