The invention relates to a gearbox, a driving system and a vehicle, and belongs to the technical field of hybrid power systems, and the gearbox and the driving system can be applied to pure electric or hybrid power road vehicles. According to the gearbox, in a speed change mechanism from an intermediate shaft to an output shaft, a gear shifting driving end for inputting power to a corresponding gear is arranged on the intermediate shaft, driving wheels of different gears are arranged on one side of the gear shifting driving end and are arranged on the intermediate shaft in a freely rotating and sleeving mode, and a gear shifting action mechanism for correspondingly achieving gear switching is achieved; for example, a gear shifting gear sleeve or a gear shifting clutch is also arranged on one side of the intermediate shaft, and when two or more intermediate shafts exist, gear shifting action mechanisms of different intermediate shafts can be overlapped to a certain extent in the axial direction of the gearbox. Compared with the scheme that gear shifting action mechanisms of speed change mechanisms between different intermediate shafts and output shafts are all arranged on one side of the output shaft, the length of the output shaft can be reduced, the length of the gearbox and the length of the whole power system can be reduced, the vehicle space is saved, and arrangement on the vehicle is facilitated.

    本发明涉及一种变速箱、驱动系统及车辆,属于混合动力系统技术领域,变速箱、驱动系统可以应用于纯电或混合动力的公路车辆。本发明的变速箱中,中间轴到输出轴的变速机构中,向对应挡位输入动力的换挡主动端设置在中间轴上,不同挡位的主动轮设置在换挡主动端的一侧,且自由转动的套设在中间轴上,相应实现挡位切换的换挡动作机构,例如换挡齿套或换挡离合器也设置在中间轴一侧,在有两个及两个以上的中间轴时,不同中间轴的换挡动作机构可以在变速箱轴向上有一定重叠。相比不同中间轴与输出轴之间的变速机构的换挡动作机构均设置在输出轴一侧的方案,能够缩小输出轴长度,减少变速箱及整个动力系统的长度,节省车辆空间,有利于在车辆上的布置。
