    • The gear consists of a four-shaft epicyclic gear, of which one shaft forms the input shaft which is in connection via an infinitely variable hydrostatic gear with the second shaft and of which the two remaining shafts represent connecting shafts which, in an extreme position of the hydrostatic gear, have the same speeds and behave during adjustment of the hydrostatic gear into the other extreme position in such a way that one becomes constantly slower and the other constantly faster, and which alternately act on the output shaft via gears of a gear group with following group shiftings. What is special is that the group shiftings make possible a multiple utilization of the gears of the gear group and that preparatory shifts for changing the group shifting provide the synchronization of idling gear parts, and that each gear change itself takes place at synchronous speeds, free from load and without tractive force interruption. Such gears require only small hydrostatic gears, have a particularly large transmission control range and favorable efficiencies. Its use in motor vehicles results in fuel savings and a superior acceleration behavior.
    • 齿轮由四轴行星齿轮组成,其中一个轴形成输入轴,该输入轴通过无级可变的静液压齿轮与第二轴连接,其中两个轴代表连接轴,其在极端位置 静液压齿轮在将静液压齿轮调节到另一个极限位置时具有相同的速度和行为,使得它们变得不断变慢,另一个变得更快,并且通过齿轮组的齿轮交替作用在输出轴上 随后进行小组转移。 特别的是,组移动可以实现齿轮组的齿轮的多次利用,并且用于改变组移位的准备移位提供空转齿轮部件的同步,并且每个齿轮变化本身以同步速度进行,自由 从负载和没有牵引力中断。 这种齿轮仅需要小型静液压齿轮,具有特别大的变速器控制范围和有效的效率。 其在汽车中的使用导致燃料节省和优异的加速行为。
