    • An integrated power transmitting system includes a hydrostatic transmission and a mechanical transmission both being driven by an engine. The output of the hydrostatic transmission and the mechanical transmission are both selectively coupled to a work system through a final output shaft. A sensing arrangement senses the transmission input speed, the output of the hydrostatic transmission and the speed of the final output shaft and delivers the signals to the microprocessor. The microprocessor processes the received signals on a continuous basis and delivers a first set of command signals to control operation of the hydrostatic transmission and a second set of control signals to selectively control forward and reverse direction and high and low clutches within the mechanical transmission. A planetary arrangement within the mechanical transmission sums the speed of the hydrostatic transmission with a full range forward and reverse gear mechanism. This arrangement provides a smooth and continuous change in the speed of a machine in both the forward and reverse directions throughout its entire speed range.
    • 集成的动力传递系统包括由发动机驱动的液压传动和机械变速器。 静液压传动装置和机械传动装置的输出通过最终输出轴选择性地耦合到工作系统。 感测装置感测变速器输入速度,静液压传动的输出和最终输出轴的速度,并将信号传送到微处理器。 微处理器连续地处理接收到的信号,并传送第一组命令信号以控制静液压变速器的操作和第二组控制信号,以选择性地控制机械变速器内的前进和后退方向以及高和低离合器。 机械传动装置内的行星装置将全液压前进和后退齿轮机构的静液压变速器的速度相加。 这种布置使机器在整个速度范围内的正向和反向方向上的速度平滑且连续地变化。
