摘　　要：液力传动因具有自动变速、操作方便等优点而受到人们的青睐。但是,由于液力变矩器的特性比较复杂,使得设计者在设计液力传动系统时比较困难。其实,当叉车爬最大坡度时液力变矩器处于最大力矩比状态附近,能够获得3左右的转矩比;而当叉车以最高速度行驶时液力变矩器处于耦合器状态,速比接近于1,通过对这两种状态的分析可以简化液力传动的设计过程。通过与机械传动系统设计的对比给出了液力传动系统的设计计算过程,概念清楚,计算简单。Hydraulic transmission gets the favor of people because of its advantages of automatic transmission and simple manipulation, and so on. However, clue to the characteristics of the more complex of torque converter, it is difficult for the designer to design the hydraulic transmission system. In fact, the hydraulic torque converter is near maximum torque ratio when forklift truck climbs the maximum slope, and the torque ratio is about 3, while the hydraulic torque converter is close to 1. In this paper, th in the coupl e design and with the mechanical transmission system, er state when forklift truck is at the highest speed, and the speed ratio calculation of the hydraulic transmission system is given by comparison the concept is clear and the calculation is simple.
