The invention discloses a main speed reducer and a vehicle. The main speed reducer comprises an input shaft, a cross shaft, a planetary gear, a first output gear, a second output gear, a first outputshaft, a transmission gear and a second output shaft, wherein the cross shaft is arranged on the input shaft, the planetary gear is rotatably arranged on the cross shaft, the first output gear is meshed with the planetary gear, the second output gear is meshed with the planetary gear, the second output gear and the first output gear are arranged at an interval, the second output gear is further selectively in transmission with the input shaft, the first output shaft is selectively in transmission with the first output gear, the first output shaft is not in transmission with the first output gear when the input shaft and the second output gear are in transmission, and the transmission gear is meshed with the second output gear and is fixed on the second output shaft. The second output gearis selectively in transmission with the input shaft, and the first output shaft is selectively in transmission with the first output gear, so that the main speed reducer can be switched between two driving paths and one driving path according to requirements.
本发明公开了一种主减速器和车辆,主减速器包括:输入轴、十字轴、行星齿轮、第一输出齿轮、第二输出齿轮、第一输出轴、传动齿轮和第二输出轴,十字轴设置于输入轴上,行星齿轮可转动地设置于十字轴,第一输出齿轮与行星齿轮啮合,第二输出齿轮与行星齿轮啮合且与第一输出齿轮间隔设置,第二输出齿轮还选择性与输入轴传动,第一输出轴选择地与第一输出齿轮传动,第一输出轴在输入轴和第二输出齿轮传动时与第一输出齿轮断开传动,传动齿轮与第二输出齿轮啮合,传动齿轮固定于第二输出轴上。通过第二输出齿轮选择性地与输入轴传动,第一输出轴选择性地与第一输出齿轮传动,使得主减速器可以根据需求在两个驱动路径和一个驱动路径之间进行转换。
