The invention relates to a dual-drive electric tricycle which structurally comprises a tricycle body, a front wheel and two rear wheels, the front wheel and the rear wheels are mounted on the tricycle body, and the two rear wheels are in driving connection with two unilateral hub motors which are bilaterally symmetrically arranged respectively. The tricycle body comprises a main frame, and the unilateral hub motors on the two sides are connected with the main frame through rear bottom forks respectively. The main frame is respectively connected with the end part and the middle part of the top surface of the rear bottom fork; and the main frame is connected with the middle part of the top surface of the rear bottom fork through a rear hydraulic shock absorber. The electric bicycle has the advantages that the two rear wheels are provided with the hub motors respectively, double drive and single drive can be freely selected according to needs in drive and energy consumption, and power is more sufficient during double drive; the single drive can greatly reduce the energy consumption of the whole vehicle and increase the endurance mileage. In terms of mechanical performance, the relatively independent hub motors can move independently, when one wheel jolts, the other wheel cannot be affected, the two relatively independent rear bottom forks are matched, an independent suspension structure is achieved, the comfort level of the whole vehicle and the stability of the tricycle body are improved, the vehicle is not prone to turning over, and safety is enhanced.
本发明是双驱动电动三轮车,其结构包括车辆本体和安装在车辆本体上的一个前轮和两个后轮,所述的两个后轮分别由左右对称设置的两个单边轮毂电机驱动连接。车辆本体包括主车架,两侧单边轮毂电机各通过一后平叉连接主车架。主车架分别与后平叉的端部和顶面中部连接,主车架与后平叉顶面中部通过后液压减震器连接。本发明的优点:两个后轮分别配置轮毂电机,驱动和能耗上可根据需要自由选择使用双、单驱动,双驱动时动力更足;单驱动可大幅降低整车能耗,增加续航里程。机械性能上相对独立的轮毂电机可单独运动,一个轮子颠簸时另一个轮子可不受影响,配合两个相对独立后平叉,实现独立悬挂结构,增加了整车舒适度和车身稳定性,不易翻车,增强了安全性。
