The invention relates to the technical field of commercial vehicle electric drive axles, and discloses a coaxial three-gear sequence gear shifting commercial vehicle electric drive axle integrated with a planet row differential reducer, which comprises a motor, a gear shifting system assembly, a speed reduction planet row assembly, a differential reduction planet row assembly and a differential lock assembly, the differential reduction planet row assembly is connected with the speed reduction planet row assembly, the differential lock assembly is arranged on one side of the differential reduction planet row assembly, a left half shaft and a right half shaft are connected to the differential reduction planet row assembly, one end of the left half shaft is located on the outer side of the gear shifting system assembly, and one end of the right half shaft is located in the differential lock assembly. The gear shifting system assembly is connected with the motor and the speed reduction planet row assembly. The sequential gear shifting structure is used, only one gear shifting system is designed, the number and weight of parts are reduced, the assembly and after-sale fault risks are reduced, and through sequential gear shifting, the possibility that a mechanical structure is fool-proof and gear skipping does not occur is achieved.
本发明涉及商用车电驱桥技术领域,公开了集成行星排差减速器的同轴式三档序列换挡商用车电驱桥,包括电机、换档系统总成、减速行星排总成、差减行星排总成、差速锁总成,所述减速行星排总成与电机连接,所述差减行星排总成与减速行星排总成连接,所述差速锁总成设在差减行星排总成的一侧上,所述差减行星排总成上连接有左半轴和右半轴,所述左半轴一端位于换档系统总成外侧,所述右半轴一端位于差速锁总成中,换挡系统总成与电机以及减速行星排总成连接。本发明通过使用序列式换挡结构,仅通过设计一套换档系统,减少零件数量和重量,减少装配,售后故障风险,且通过序列式换挡,存在机械结构防呆,不会发生跳档的可能性。
