传统的装载机变速器换挡系统，一般采用机械式换挡，靠多个杠杆机构通过软轴推拉变速阀杆，达到换挡目的。这种结构虽然能实现远距离换挡，但杠杆机构往往很复杂，间隙调整也较麻烦。而且由于磨损，必须经常调整间隙，否则会出现乱挡或无挡现象。 山东临沂工程机械股份有限公司
Traditional loader gearbox shift system, the general use of mechanical shift, by a number of lever mechanism through the flexible shaft to push and pull the shift valve stem, to shift the purpose. Although this structure can achieve long-range gear shift, but the lever mechanism is often complicated, clearance adjustment is also more troublesome. And because of wear and tear, you must always adjust the gap, otherwise there will be disorderly block or no block phenomenon. Shandong Linyi Construction Machinery Co., Ltd.
