    • A drive system for propelling a power machine over a support surface is disclosed. The drive system includes a hydraulic pressure source and a drive assembly. The drive assembly has a hydraulic motor in fluid communication with the hydraulic pressure source that is switchable between first and second displacement arrangements. A shift valve receives pressurized fluid from the hydraulic pressure source and provides a shift signal to the hydraulic motor to selectively cause the displacement of the hydraulic motor to shift between the first and second displacement arrangements. A sensing device capable of generating a load signal indicative of a load condition provided by the drive assembly is also provided. An electronic controller provides a control signal to the shift valve to control the displacement of the hydraulic motor in response at least in part due to the load signal.
    • 公开了一种驱动系统,用于将动力机械推动在支撑表面上。 驱动系统包括液压源和驱动组件。 驱动组件具有与液压源流体连通的液压马达,其可在第一和第二排量装置之间切换。 换档阀从液压源接收加压流体,并向液压马达提供换档信号,以选择性地使液压马达的位移在第一和第二排量装置之间移动。 还提供能够产生指示由驱动组件提供的负载状况的负载信号的感测装置。 电子控制器向变速阀提供控制信号,至少部分地由于负载信号而响应于液压马达的位移。
