行走机械的液压复合传动技术

根据行走机械对传动装置的要求，来分析比较机械、液力、液压和电力等四种传动方式的优缺点，并指出发展复合传动技术是现代传动技术发展的主要趋势之一。在复合传动技术中，兼有调节和布局灵活性和高功率密度的液压传动装置担当着重要角色．并应对液压机械功率流技术予以特别关注。

Hydraulic combination transmissions technology in mobile machinery

Following the requirements of transmission for mobile machinery, this paper analyzes and compares to the merits and shortcuts of their four types of transmission, i.e. mechanically, hydro-dynamically, hydro-statically and electronically. This paper al-so indicates the developing the combination transmissions in one of the main trends for modern transmission technology in which the hydraulic transmission with the features of adjustable, flexible of assignment and high power density is the key role. The technol-ogy of power shunt in the hydraulic transmissions should be especially paid more attention so far.
