摘要： 为了获得一种小型化、轻量化、紧凑化、多挡位、低成本化的适用于拖拉机重型载荷 的变速箱结构，参考后桥中行星齿轮系改变传动比的思想，将其引入变速箱结构，设计了一 种基于行星齿轮系的新型多挡位变速箱。经计算主变速器共产生 8 种工况，副变速器共 2 种 前进挡位和 1 种倒挡挡位，即理论上存在 24 种挡位变化形式。后采取 MATLAB 编程方法进 行齿数匹配，发现当 Z4=54、Z5=30、Z6=74、Z7=27 时主变速八种传动比为 0.27、0.50、0.73、 0.90、1.36、1.37、1.99、2.47，基本符合变速要求。介绍了多挡位新型变速箱结构和动力传 递方式，可以为后续新型变速箱的开发提供理论参考。

Abstract: To obtain a miniaturised, lightweight, compact, multi-gear, low-cost gearbox structure suitable for heavy tractor loads, a new multi-gear transmission based on a planetary gear system was designed by referring to the idea of changing the transmission ratio in a rear axle and introducing it into the transmission structure. A total of 8 operating conditions were calculated for the main transmission and 2 forward gears and 1 reverse gear for the secondary transmission, i.e. 24 theoretical forms of gear changes exist. After taking MATLAB programming method to match the number of teeth, it was found that when Z4=54, Z5=30, Z6=74 and Z7=27 the eight ratios of the main transmission are 0.27, 0.50, 0.73, 0.90, 1.36, 1.37, 1.99 and 2.47, which basically meet the gearing requirements. The structure and power transmission of the new multi-gear gearbox introduced in this paper can provide theoretical reference for the development of subsequent new gearboxes.
