The invention belongs to the technical field of vehicle engineering and provides a through drive axle and a multi-drive axle system.The through drive axle comprises a transmission shaft system and an inter-axle transfer unit, and the inter-axle transfer unit comprises a transfer case shell, a planet carrier, an inter-axle planet gear, a gear ring support, an inner gear ring and a driving cylindrical gear; one axial end of the transfer case shell is in transmission connection with the power input flange, a meshing inner cavity is formed in the other end of the transfer case shell, the planet carrier is arranged in the meshing inner cavity in a meshing mode, and the inter-shaft planet gear is rotationally arranged on the planet carrier and meshed with the inner gear ring and the driving cylindrical gear to form a planet gear train. According to the through drive axle disclosed by the invention, the structures and the arrangement forms of the transmission shaft system and the inter-shaft transfer unit are optimized, so that the length of the second output shaft can be shortened, and the internal structure of the through drive axle is more compact.
本发明属于车辆工程技术领域并提供一种贯通驱动桥及多联驱动车桥系统,贯通驱动桥包括传动轴系和轴间分动单元,轴间分动单元包括分动器壳体、行星架、轴间行星齿轮、齿圈支架、内齿圈和主动圆柱齿轮,分动器壳体的轴向一端与动力输入法兰传动连接,另一端设有啮合内腔,行星架啮合设置在啮合内腔内,轴间行星齿轮转动设置在行星架上并分别与内齿圈以及主动圆柱齿轮啮合构成行星轮系,主动圆柱齿轮滑动套接在第一输出轴上并且延伸端与第二输出轴的外啮合,本发明中的贯通驱动桥通过对传动轴系以及轴间分动单元的结构以及布置形式进行优化,从而能够缩短第二输出轴长度,并使贯通驱动桥的内部结构更加紧凑。
