我厂生产的ZL50装载机的变速器是定轴式、四进四退、液力机械操纵的(离合器是液力操纵,输出轴上的高低档是机械操纵),70年代它被用在TL160推土机上。经过多次攻关、试验和改进,达到了制造容易、使用可靠、维修方便,已用于TL180、TL210推土机,ZL50、ZL60装载机和TL12通井机上,装机功率118～190kW。但由于高低档是机械操纵,换档时要停车进行,因此仍然限制着其使用范围,不宜用到以运输为主的车辆(如铲运机、牵引车等)上,因为由低档换上高档后,重新起步很困难,甚至不能起步。 近年来,我对这个变速器进行了分析研究,现提出几个改进方案,希望进一步扩大其
ZL50 loader I produced the transmission is fixed axis, four into four retreat, hydraulic mechanical manipulation (clutch hydraulic control, high and low output shaft is the mechanical control), it was used in the 70’s TL160 bulldozer on. After many tackling, testing and improvement, it has been easy to manufacture, reliable to use and easy to maintain. It has been used in TL180, TL210 bulldozer, ZL50, ZL60 loader and TL12 well drilling machine with installed power of 118 ~ 190kW. However, due to the high and low gear is mechanical control, shift to stop, it still limits the scope of its use, should not be used to transport vehicles (such as scrapers, tractors, etc.), because the low into the high After the start is very difficult, can not even start. In recent years, I have carried on the analysis and research to this transmission, have put forward some improvement schemes now, hope to further expand its
