The invention discloses a middle-mounted transmission sensing variable-speed electric driving system which comprises a power mechanism, a variable-speed transmission mechanism, a transmission sensingmechanism, a main shaft and a power output sleeve which is synchronously and rotationally arranged on the main shaft in a sleeving manner, and the transmission sensing mechanism is located on one sideof the power output sleeve. The power mechanism and the variable-speed transmission mechanism are positioned on the other side of the power output sleeve; the variable-speed transmission mechanism comprises a gear shifting speed reduction assembly, a gear shifting synchronizer, an overrunning clutch and a power input element, wherein the gear shifting synchronizer, the overrunning clutch and thepower input element sleeve the main shaft. By the adoption of the technical scheme, the automatic gear shifting function can be achieved according to the real-time power condition, an electric two-wheeled vehicle can be matched with the actual driving working condition and the motor working condition in a self-adaptive mode according to the resistance condition, the electric two-wheeled vehicle has high climbing and heavy load capacity, the motor can be located on an efficient platform all the time, the efficiency of the motor under climbing and heavy load conditions is greatly improved, and the energy consumption of the motor is reduced.

    本发明公开了一种中置式传动传感变速电驱动系统,包括动力机构、变速传动机构、传动传感机构、主轴以及同步转动地套装在主轴上的动力输出套,所述传动传感机构位于动力输出套的一侧,所述动力机构和变速传动机构位于动力输出套的另一侧;其中,所述变速传动机构包括换挡减速组件以及均套装在主轴上的换挡同步器、超越离合器和动力输入元件。采用以上技术方案,能够根据实时功率情况进行自动换挡的功能,使电动两轮车能够根据阻力情况,自适应匹配实际行驶工况与电机工况,不仅使电动两轮车具有强大的爬坡和重载能力,而且使电机能够始终处于高效平台上,大大提高了电机在爬坡和重载情况下的效率,降低了电机能耗。
