The invention discloses a two-gear transmission for an electric automobile and an automobile. The two-gear transmission comprises an input shaft freely sleeving a half shaft of a differential mechanism, wherein an intermediate shaft I and an intermediate shaft II are arranged on the two sides of the input shaft; the intermediate shaft I and the intermediate shaft II are arranged in a symmetrical structure, parallel to the input shaft, and used for receiving power transmitted by the input shaft; a first-gear gear freely sleeves the intermediate shaft I and is connected with a clutch I which isarranged on the intermediate shaft I; the intermediate shaft I is further provided with a transmission mechanism I which is in transmission connection with the differential mechanism; a second-gear gear freely sleeves the intermediate shaft II and is connected with a clutch II which is arranged on the intermediate shaft II; and the intermediate shaft II is further provided with a transmission mechanism II which is in transmission connection with the differential mechanism. The two-gear transmission for the electric automobile and the automobile have the beneficial effects that the clutches areadopted for gear shifting, and the situation that synchronizers are adopted by an original two-gear transmission for gear shifting is replaced, so that the gear shifting time of the electric automobile is shortened, and the driving and riding comfort of the automobile is improved while the power performance and the driving range of the automobile are effectively improved.
本发明揭示了一种电动汽车用两挡变速器及汽车,包括空套在差速器半轴上的输入轴,所述输入轴的两侧设有呈对称结构设置且与其相平行用以接收其传输的动力的中间轴I和中间轴II,所述中间轴I上空套有一挡齿轮,所述一挡齿轮与设置在中间轴I上的离合器I连接,所述中间轴I上还设有与差速器传动连接的传动机构I;中间轴II上空套有二挡齿轮,所述二挡齿轮与设置在中间轴II上的离合器II连接,所述中间轴II上还设有与差速器传动连接的传动机构II。本发明的有益效果主要体现在:采用离合器进行换挡,代替了原有的两挡变速器通过同步器进行换挡,使得电动车换挡时间变短,可以有效地提高车辆动力性和续驶里程的同时提高车辆驾驶及乘坐的舒适性。
