The invention discloses a two-gear automatic transmission and an automobile. The two-gear automatic transmission comprises an input shaft which is hollowly sleeved on a differential half shaft, a motor is fixedly arranged on the input shaft, the central axes of the motor, the input shaft and the differential half shaft are coaxial; and an intermediate shaft parallel to the input shaft and used forreceiving power transmitted by the input shaft is arranged on one side of the input shaft, a first-gear gear pair and a second-gear gear pair are arranged between the intermediate shaft and the differential, and a synchronizer which can be selectively coupled with the first-gear gear pair or the second-gear gear pair is arranged between the first-gear gear pair and the second-gear gear pair. Thebeneficial effects of the two-gear automatic transmission and the automobile is mainly characterized in that the output shaft and the input shaft of the differential are coaxially arranged, the longitudinal size of the transmission is reduced, the support of a bearing arranged in the inner part of a transmission shell is combined, the overall rigidity is ensured, and meanwhile, the structure is more compact, the size is small, and whole automobile carrying is facilitated.

    本发明揭示了一种两挡自动变速器及汽车,所述两挡自动变速器包括空套在差速器半轴上的输入轴,所述输入轴上固设有一电机,所述电机、输入轴以及差速器半轴的中轴线共轴;所述输入轴的一侧设有与其平行设置用以接收所述输入轴传输的动力的中间轴,所述中间轴与差速器之间设有一挡齿轮副和二挡齿轮副,所述一挡齿轮副和二挡齿轮副之间设有一可选择性地与所述一挡齿轮副或二挡齿轮副耦合的同步器。本发明的有益效果主要体现在:差速器的输出轴与输入轴共轴设置,减小变速器的纵向尺寸,并结合设置在变速器壳体内部的轴承的支持,确保整体的刚性,同时,使得本发明结构更紧凑,体积小,有利于整车搭载。
