目前,在工程和矿用机械中,液力传动的发展是令人欣喜的。据了解,产品更新的主要特征体现在两个方面:一是液力变矩器本身结构和性能的改进,如各种变能容液力变矩器的出现就是这一特征的主要标志;二是传动系各部件连接形式的变更,如变矩器和变速器的分装与合装是两种不同的连接形式的反映。本文所讨论的液力变速器正是这两方面特征的综合。就变矩器本身来说,它将一般变矩器的导轮固定叶片改进为可控转动叶片,这就将变矩器性能上的自控发展为人控了;就连接形式而言,它打破了传统的变矩器直接与发动机曲轴相连的方式,而是象图1那样,将几个不同作用的变矩器连接到变速器中完成特定功能的传动轴上。这种新型液力变速器是八十年代出现的先进产品,已经在国外大型装载机上应用,据称是迄今最优良的传动系部件。现就这一
At present, in engineering and mining machinery, the development of hydraulic transmission is gratifying. It is understood that the main features of product updates reflected in two aspects: First, the structure and performance improvement of the torque converter itself, such as the emergence of a variety of energy-tolerant torque converter is the main symbol of this feature; It is the change of the connection form of each part of the transmission system. For example, the sub-assembly and assembly of the torque converter and the transmission are the reflection of two different connection forms. The hydraulic transmission discussed in this article is the combination of these two aspects. As far as the torque converter itself is concerned, it improves the stator blade of a conventional torque converter to a controlled rotor blade, which develops the automatic control of the performance of the torque converter into a human controlled one; it breaks down in the connection form Instead of connecting the conventional torque converter directly to the crankshaft of the engine, several differently acting torque converters, like the one shown in FIG. 1, are connected to the transmission shaft to perform a specific function. This new hydraulic transmission is an advanced product that appeared in the eighties and has been applied on large foreign loaders and is said to be the best driveline component to date. Now this one
