工程及矿山机械上使用液力变矩工器，具有起步平稳，操作方便，可在较大范围内实现无级变速等优点。因此，液力变矩器在工程机械中得到了广泛的应用。国内轮式装载机上应用的双导轮综合式液力变矩器，具有高效区宽广，变矩过渡至偶合工况平稳的特点。但这种变矩器在使用时间较?
Engineering and mining machinery using hydraulic torque converter, with a smooth start, easy to operate, can be achieved within a wide range of CVT advantages. Therefore, torque converter in construction machinery has been widely used. Dual-wheel integrated hydraulic torque converter applied on domestic wheel loaders has the characteristics of wide range of high efficient area and transition of torque to coupling condition. But this torque converter in use time?
