【摘要】：随着液压传动技术的发展,液压机械无级变速器在工程机械、农业机械得到广泛应用。对液压机械无级变速器结构、工作原理及关键性能参数进行了研究,通过分析其功率输送方式,推导速比、液压功率分流比及系统效率计算公式,并建立速比曲线、功率分流比曲线及效率曲线,发现系统效率优于纯液压调速方式并得到负载调速方法,最后给出了其在工程机械与农业机械领域的应用案例。
[Abstract]:With the development of hydraulic transmission technology, hydraulic machinery stepless transmission has been widely used in construction machinery and agricultural machinery. The structure, working principle and key performance parameters of hydraulic machinery stepless transmission have been studied. Through the analysis of its power transmission mode, the formula for calculating the speed ratio, hydraulic power split ratio and system efficiency is derived, and the speed ratio curve, power distribution ratio curve and efficiency curve are established. It is found that the system efficiency is superior to the pure hydraulic speed regulation method and the load speed regulation method is obtained. Finally, the application cases in the field of construction machinery and agricultural machinery are given.
