A two speed transmission system (104) for an electric vehicle is disclosed. The system (104) comprises: a housing (208); a one-way clutch assembly (210) adapted to be mounted on the input shaft (212) and coupled with the first gear drive assembly (302); a multi-plate friction clutch assembly (306) adapted to be mounted on the input shaft (212) and having a clutch hub (304) disposed in the housing and mounted on the input shaft (212); a second gear drive assembly (306) is freely mounted on the input shaft (212) and has an external spline on an outer diameter adapted to engage a clutch hub (304) of the multi-plate friction clutch assembly (306). The one-way clutch assembly (210) is adapted to rotate to cause the vehicle to actuate in the first gear drive when the input shaft (212) is rotated in the drive direction, and the multi-plate friction clutch assembly (214) is in a disengaged state when the vehicle is operating in the first gear drive.
公开了一种用于电动车辆的双速传动系统(104)。该系统(104)包括:壳体(208);单向离合器组件(210),其适于安装在输入轴(212)上并与第一齿轮驱动组件(302)联接;多片式摩擦离合器组件(306),其适于安装在输入轴(212)上并且具有布置在壳体中并安装在输入轴(212)上的离合器毂(304);第二齿轮驱动组件(306),其自由地安装在输入轴(212)上并且在外径上具有适于与多片式摩擦离合器组件(306)的离合器毂(304)接合的外部花键。当输入轴(212)沿驱动方向旋转时,单向离合器组件(210)适于旋转以使车辆在第一齿轮驱动部中造作,并且当车辆在第一齿轮驱动部中操作时,多片式摩擦离合器组件(214)处于断开接合状态。
