The invention relates to the field of transmission devices, in particular to a multi-gear five-wheel transmission mechanism of a tractor. A fifth wheel and a five-wheel transmission are arranged in the tractor. The five-wheel transmission comprises an input shaft, a reverse gear driving gear, a high gear driving gear and a lower gear driving gear. A reverse gear intermediate gear is mounted on a reverse gear middle shaft. A gear shifting driving gear, a reverse gear driven gear, a high gear driven gear and a low gear driven gear are mounted on a back output shaft. A gear shifting driven gear is mounted on a front output shaft, a gear shifting intermediate gear I and a gear shifting intermediate gear II are mounted on an output intermediate shaft, the front end of the back output shaft andthe back end of the front output shaft are connected or disconnected through a third engagement sleeve, and a fourth engagement sleeve linked to the third engagement sleeve is arranged on one side ofthe gear shifting driven gear. The multi-gear five-wheel transmission mechanism is convenient to operate, high in work efficiency and safe and reliable.
本发明涉及传动装置领域,具体的说是一种拖拉机多档位五轮传动机构,拖拉机内设有第五轮和五轮变速箱。五轮变速箱包括输入轴、倒档中间轴、输出中间轴、后输出轴和前输出轴。输入轴上安装有倒档主动齿轮、高档主动齿轮和低档主动齿轮。倒档中间轴上安装有倒档中间齿轮。后输出轴上安装有变档主动齿轮、倒档从动齿轮、高档从动齿轮和低档从动齿轮。前输出轴上安装有变档从动齿轮,输出中间轴上安装有变档中间齿轮一和变档中间齿轮二,后输出轴前端与所述前输出轴的后端通过第三啮合套连接或断开,变档从动齿轮一侧设有与第三啮合套联动的第四啮合套。本发明操作方便,工作效率高,安全可靠。
