The invention discloses a wheel-side self-adaptive automatic speed change electric drive hub which comprises a hub body with an installation cavity and a self-adaptive automatic speed change system arranged in the installation cavity. The self-adaptive automatic speed change system comprises a power mechanism, a high-speed gear transmission mechanism, a low-speed gear transmission mechanism, a main shaft and a power output sleeve, wherein the main shaft is sleeved with the power output sleeve in a synchronous rotating mode. By the adoption of the technical scheme, a brand-new wheel-side electric drive system is formed, the structure is compact, the overall arrangement of the two-wheeled vehicle is not affected, the reduction ratio is large, and the output torque can be effectively increased; meanwhile, the actual driving working condition and the motor working condition of the electric vehicle can be matched in a self-adaptive mode according to the resistance condition, so that the motor is located on an efficient platform all the time while the electric vehicle has strong climbing and heavy-load capacity, the efficiency of the motor under the climbing and heavy-load conditions isgreatly improved, and the energy consumption of the motor is reduced.
本发明公开了一种轮边自适应自动变速电驱动轮毂,包括具有安装腔室的轮毂本体以及设置在安装腔室中的自适应自动变速系统,所述自适应自动变速系统包括动力机构、高速挡传动机构、低速挡传动机构、主轴以及同步转动地套装在主轴上的动力输出套。采用以上技术方案,构成了全新的轮边电驱动系统,不但结构紧凑,不影响两轮车的整车布置,而且具有较大减速比,能够有效提升输出扭矩;同时能够根据阻力情况,自适应匹配电动交通工具的实际行驶工况与电机工况,使电动汽车具有强大的爬坡和重载能力的同时,使电机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。
