The invention belongs to the technical field of transmissions, and particularly relates to a center shaft transmission and a middle motor. According to the center shaft transmission and the middle motor, the gear ring of the planetary gear mechanism is locked or loosened by controlling the fixing mechanism, so that the transmission ratio of the center shaft transmission is changed, and the gear shifting function is achieved. On the premise that the size and the total transmission ratio of the center shaft transmission are consistent, the meshing center distances of the multiple sets of planetary gear mechanisms are made to be the same, so that planetary gears of all the sets of planetary gear mechanisms are hinged to the same planet carrier and are coaxial, the machining procedures can be reduced when the planet carrier is machined, repeated or unnecessary operation is avoided, and the machining efficiency is improved. Meanwhile, a plurality of planetary gears can be mounted on the planetary carrier at the same time, so that the effect of reducing assembly procedures is achieved, the probability of errors is reduced, and the quality and reliability of products are improved.

    本发明属于变速器技术领域,特别涉及一种中轴变速器及中置电机。本发明的中轴变速器及中置电机,通过控制固定机构对行星齿轮机构的齿圈进行锁止或松开,使中轴变速器变更传动比,进而实现换挡的功能。在中轴变速器体积和总传动比一致的前提下,通过使多组行星齿轮机构的啮合中心距均相同,从而使每组行星齿轮机构的行星齿轮铰接在同一行星架上且同轴,那么在加工行星架时能够减少加工工序,避免重复或不必要的操作,提高生产效率,同时多个行星齿轮可以同时安装到行星架上,起到减少装配工序的作用,降低出错的机会,提高产品的质量和可靠性。
