The invention belongs to the technical field of automobile power transmission systems, and particularly relates to a multi-gear speed control system, an electric drive assembly and a vehicle chassis. The speed control system inputs power through a plurality of input shafts arranged side by side, is provided with a plurality of power sources, can be provided with a high-speed and small-torque motor, and is smaller in size; power is decelerated through cooperation of the input gear installed on the input shaft and the first driven gear, transmitted to the intermediate shaft, decelerated through the action of the first gear shifting mechanism or the second gear shifting mechanism, transmitted to the driving shaft and output through third-time deceleration through the action of the output gear and the output end, and multi-gear three-level deceleration of the power is achieved. According to the electric drive assembly, the high speed and small torque of the power motor are achieved through the multi-gear speed change system, the use amount of rare earth permanent magnet materials of motor products is reduced, the weight, the size and the cost of the power motor are effectively reduced, meanwhile, the high-speed small-torque multi-gear speed change system is adopted, and the overall weight and the overall size of the electric drive assembly are effectively reduced.

    本发明属于汽车动力传动系统技术领域,具体是涉及到一种多挡位变速系统、电驱动总成及车辆底盘,变速系统多个并排设置的输入轴输入动力,具有多个动力源,可以配备高速小扭矩的电机,体积也更小,动力经输入轴上安装的输入齿轮与从动齿轮一配合进行减速,动力传递至中间轴,再通过换挡机构一或换挡机构二的作用,再进行减速,将动力传递至驱动轴后,经过输出齿轮与输出端的作用第三次减速输出,实现动力的多挡位三级减速,电驱动总成通过多挡位变速系统实现了动力电机的高速小扭矩化,降低电机产品稀土永磁材料用量,有效降低动力电机的重量、体积及成本,同时采用高速小扭矩多挡位变速系统,有效降低电驱动总成的整体重量体积。
