The invention relates to a transmission and an automobile. The transmission comprises a shell, a first deep groove ball bearing, an input shaft, a first elastic piece and a first thrust bearing, whenthe transmission is in a high-rotating-speed and low-torque state, the elastic force applied to the first deep groove ball bearing by the first elastic piece can enable a first surface to be located at the separation position separated from the first thrust bearing so that the situation that the first thrust bearing is damaged due to bearing of the high rotating speed can be prevented, and then the maximum rotating speed of the transmission can be increased; and when the transmission is in a low-rotating-speed and high-torque state, the axial force pointing to the first deep groove ball bearing can overcome the elastic force of the first elastic piece, so that the first surface abuts against the first thrust bearing, then the first thrust bearing can unload the axial force borne by the first deep groove ball bearing, and then the maximum torque of the transmission can be increased. By means of the technical scheme, the transmission can improve both the maximum rotating speed and the maximum torque.

    本发明涉及变速器及汽车。变速器包括:壳体、第一深沟球轴承、输入轴、第一弹性件以及第一推力轴承。变速器处于高转速低扭矩的状态时,第一弹性件作用于第一深沟球轴承的弹性力能够使得第一表面处于与第一推力轴承分离的分离位置,从而可以防止第一推力轴承由于承受高转速而损坏,进而可以使变速器高提高最大转速;变速器处于低转速高扭矩的状态时,指向第一深沟球轴承的轴向力能够克服第一弹性件的弹性力,使得第一表面与第一推力轴承抵接,从而第一推力轴承可以卸载第一深沟球轴承承受的轴向力,进而可以使变速器高提高最大扭矩。通过上述技术方案,变速器既能够提高最大转速又能够提高最大扭矩。
