The invention provides a gear shifting mechanism, a transmission and a vehicle. The gear shifting mechanism comprises a driving motor and a transmission assembly. The driving motor comprises a motor shell, a stator assembly, a rotor assembly and a worm, and the rotor assembly is connected with the worm; the transmission assembly comprises a gear box, a gear arranged in the gear box and an output shaft arranged on the gear, the gear is provided with a plurality of buffering cavities and a connecting part, the buffering cavities are evenly arranged around the connecting part, buffering elastic pieces are arranged in the buffering cavities, and the output shaft is connected with the connecting part; and the worm extends into the gear box and is meshed with the gear. According to the gear shifting mechanism, the buffering effect can be achieved through the buffering elastic piece, so that the purposes of buffering, preventing shock and reducing the impact force borne by the gear from the output shaft are achieved, the service life of the gear and the service life of the driving motor are effectively prolonged, and through transmission cooperation of the worm and the gear, the overall structure is reliable and stable, and cost is low.
本发明提供一种换挡机构、变速器和车辆,换挡机构包括:驱动电机和传动组件;所述驱动电机包括电机外壳、定子组件、转子组件和蜗杆,所述转子组件与所述蜗杆连接;所述传动组件包括齿轮箱、设置在所述齿轮箱内的齿轮和设置在所述齿轮的输出轴,所述齿轮上设置有多个缓冲腔和连接部,所述缓冲腔环绕所述连接部均匀布置,所述缓冲腔内设置有缓冲弹性件,所述输出轴与所述连接部连接;所述蜗杆伸入所述齿轮箱并且与所述齿轮啮合。本发明的换挡机构能够可通过缓冲弹性件产生缓冲作用,从而达到缓冲、防震、降低齿轮所受的来自输出轴的冲击力的目的,有效增长齿轮和驱动电机的使用寿命,通过蜗杆和齿轮传动配合,使得整体结构可靠稳定,成本较低。
