The invention discloses a four-gear middle-mounted chain transmission electric drive self-adaptive speed change system which is characterized in that a power input mechanism transmits power to an out-wheel intermediate shaft through a high-gear transmission mechanism or a low-gear transmission mechanism, and the out-wheel intermediate shaft transmits the power to a driving wheel through a chain transmission assembly and a two-gear transmission mechanism in sequence. By adopting the technical scheme, the power input mechanism, the high-speed gear transmission mechanism and the low-speed gear transmission mechanism are arranged in the middle of the original two-wheeled vehicle, and the two-gear transmission mechanism is additionally arranged at the position of the driving wheel, so that four-gear speed change is formed, a speed reduction transmission path is prolonged, and the speed reduction ratio is increased, and a high-speed motor can be adopted for driving; meanwhile, a chain transmission mode is reserved, and 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.

    本发明公开了一种四挡中置式链条传动电驱动自适应变速系统,动力输入机构通过高速挡传动机构或低速挡传动机构将动力传递给轮外中间轴,轮外中间轴再依次通过链条传动组件和两挡传动机构将动力传递给驱动轮。采用以上技术方案,将动力输入机构、高速挡传动机构和低速挡传动机构设置在原始的两轮车中间位置,在驱动轮的位置增设两挡传动机构,不仅形成四挡变速,而且延长了减速传动路径,增大了减速比,从而能够采用高速电机作为驱动,同时保留链条传动的方式,并且,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。
