郑工产ＺＬ５０轮式装载机的变速器采用常啮合圆柱齿轮传动，液压离合器与机械传动综合换挡。变速器将液力变矩器传来的动力，通过油液压力接合不同挡位的离合器，得到不同的速度，再传给前、后桥。 其常见故障主要有：挂不上挡；只有前进挡无后退挡；只有Ⅰ挡无Ⅱ挡；只有高速
Zheng production ZL50 wheel loader transmission with constant meshing cylindrical gear transmission, hydraulic clutch and mechanical transmission integrated shift. Transmission torque converter will come from the power, hydraulic clutch pressure through the engagement of different gears, get a different speed, and then passed to the front and rear axle. The common faults are: hanging up the block; only the forward block without reverse gear; only Ⅰ block without Ⅱ block; only high-speed
