The invention provides a planetary gear set, an electric drive system, a vehicle and an electric drive system control method.The planetary gear set comprises a gear tooth part and an output end, the gear tooth part is arranged on the periphery of the planetary gear set, and the output end is arranged on a gear shaft of the planetary gear set; the gear tooth part is suitable for being connected with a driving shaft which is coaxially arranged with the driving assembly, and the output end is suitable for being arranged on an output shaft in a sleeving mode. Transmission is directly conducted through the gear tooth part, transmission links are reduced, therefore, the power transmission efficiency is improved, and energy loss is reduced. Meanwhile, compared with a traditional parallel shaft and planet row structure, an intermediate shaft is omitted, the transverse size needed by the first planet carrier can be reduced while the same transmission ratio is achieved, and the whole electric drive system is more compact in structure. The compact structural design not only facilitates the flexibility of the arrangement of the whole vehicle, but also provides more space for the expansion of other important parts or passenger compartments, and improves the practicability and comfort of the vehicle.
本申请提供一种行星轮组、电驱系统、车辆及电驱系统控制方法,其中,所述行星轮组包括轮齿部和输出端,所述轮齿部设置于所述行星轮组的外周,所述输出端设置于所述行星轮组的轮轴上,所述轮齿部适于与驱动组件同轴配置的驱动轴连接,所述输出端适于套设于输出轴。本申请直接由轮齿部进行传动,减少了传动环节,从而提高了动力传输效率,减少了能量损失。同时,相较于传统的平行轴加行星排结构取消了中间轴,可以在实现相同传动比的同时,减小第一行星架所需的横向尺寸,使得整个电驱系统结构更加紧凑。这种紧凑的结构设计不仅有利于整车布置的灵活性,也为其他重要部件或乘客舱的扩展提供了更多空间,提升了车辆的实用性和舒适性。
