某ZL50装载机采用液压与液力机械传动,具有变速平稳、传动比大、作业效率高和无级变速等特点,应用十分广泛。其变速器采用行星齿轮式动力换挡变速器,换挡操作系统为液压式。在使用中有时出现换挡冲击故障,即换挡后装载机不能平缓起步,而是出现短暂的动力传递中断而后猛然结合使整机出现荷载冲击的现象。液力机械传动方式涉
A ZL50 loader with hydraulic and hydraulic mechanical transmission, with a stable speed, large transmission ratio, high efficiency and continuously variable speed and other characteristics, the application is very wide. The transmission planetary gear-type power shift transmission, shift operating system for the hydraulic. In use sometimes shift shock failure, that is, after the shift loader can not be a smooth start, but there is a brief interruption of power transmission and then suddenly combined with the whole machine load shock phenomenon. Hydraulic mechanical transmission involved
