摘要
针对目前液力机械综合传动系统传动效率较低,同时进一步提升传动效率难度大等问题,提出了一种高效双模逻辑机械综合传动总体方案,分析了该方案的系统结构组成,其中双模逻辑行星变速机构是该系统的关键部件.利用行星传动理论,建立了该类行星变速机构的模块化设计方法,并分析了双模逻辑行星变速机构的工作原理.对直驶和转向总体性能进行分析,计算结果表明:双模逻辑机械综合传动能有效提高传动效率、发动机功率利用率和转向行驶稳定性.
The problem of current hydro-mechanical transmission for tracked vehicles is that its efficiency is relatively low and very difficult to be improved. A scheme of binary logic mechanical integrated transmission with higher efficiency is presented and its system structure components are analyzed including the key component--the binary logic planetary gearbox in the paper. The module design method is built according to the planetary gear transmission theory and explains the principle of binary logic planetary gearbox. The performance of steering and driving is analyzed and the results prove that binary logic mechanical integrated transmission is able to improve the transmission efficiency, make full use of engine power and provide much more stable steering.
