The invention relates to the technical field of electric drive axles, and discloses a multi-gear integrated electric drive axle assembly and an engineering vehicle, the multi-gear integrated electric drive axle assembly comprises a first-stage transmission shaft, a second-stage transmission shaft, a third-stage transmission shaft, a fourth-stage transmission shaft and an output shaft which are arranged in parallel, and the first-stage transmission shaft is driven by a motor and is directly connected with the output shaft of the motor; the output shaft is connected with the differential; a first gear shifting mechanism and a second gear shifting mechanism are arranged on the third-stage transmission shaft, and a third gear shifting mechanism is arranged on the first-stage transmission shaft; a first-gear gear pair and a second-gear gear pair are arranged between the second-stage transmission shaft and the third-stage transmission shaft in parallel, and a third-gear gear pair is arranged between the first-stage transmission shaft and the fourth-stage transmission shaft. The three gears are direct gears, power of the motor is directly input into the first-stage transmission shaft and then transmitted to the differential mechanism of the output shaft through frequent meshing with the gear pair, the transmission path is short, the transmission efficiency is high, energy consumption is small, the structure is compact, and space is saved.
本发明涉及电驱桥技术领域,公开了多挡集成电驱桥总成及工程车辆,多挡集成电驱桥总成包括平行布置的一级传动轴、二级传动轴、三级传动轴、四级传动轴和输出轴,一级传动轴由电机驱动,且和电机的输出轴直连;输出轴连接差速器;三级传动轴上设有第一换挡机构和第二换挡机构,一级传动轴上设有第三换挡机构;二级传动轴和三级传动轴之间并列设有一挡齿轮副和二挡齿轮副,一级传动轴和四级传动轴之间通过三挡齿轮副。本发明三挡为直接挡,电机的动力直接输入一级传动轴,再经常啮合齿轮副传递至输出轴的差速器中,传递路径短,传动效率高,能耗小,结构紧凑,节省空间。
