The embodiment of the invention discloses a parallel-axis electric drive axle with a planet row; the parallel-axis electric drive axle comprises a drive motor, a planet gear reducing mechanism, a first gear, a second gear, a differential mechanism and a shell, and the second gear is coaxial with the differential mechanism. A power output shaft of the drive motor is connected with the input end of the planetary gear reducing mechanism, the output end of the planetary gear reducing mechanism is connected with the first gear, the first gear is meshed with the second gear, the second gear is fixedly connected with the differential mechanism, and the differential mechanism is connected with the wheels. According to the parallel-axis electric drive axle with the planet row provided by the embodiment of the invention, transmission is carried out through the planet gear speed reducing mechanism, and the transmission efficiency and the transmission stability of the planet gear speed reducing mechanism are both higher than those of common three-axis parallel-axis transmission; and the noise generated by the planetary gear speed reducing mechanism is smaller than that generated by common three-shaft parallel shaft transmission, so that the transmission efficiency can be improved, the transmission stability can be improved, the noise is low, and the transmission effect is further improved.
本发明实施例公开一种带行星排的平行轴电驱动桥,包括驱动电机、行星齿轮减速机构、第一齿轮、第二齿轮、差速器和壳体,第二齿轮与差速器同轴。驱动电机的动力输出轴与行星齿轮减速机构的输入端连接,行星齿轮减速机构的输出端与第一齿轮连接,第一齿轮与第二齿轮啮合,第二齿轮与差速器固定连接,差速器与车轮连接,可见,本发明实施例提供的带行星排的平行轴电驱动桥是通过行星齿轮减速机构进行传动的,由于行星齿轮减速机构的传动效率和传动平稳性均高于普通三轴平行轴传动的传动效率和传动平稳性,且行星齿轮减速机构产生的噪音小于普通三轴平行轴传动产生的噪音,因此,可以提高传动效率、提高传动平稳性且噪音较小,进一步提高传动效果。
