目前,各种轮式、履带式车辆普遍使用的行走系除机械传动系外,还普遍使用液力机械传动系。如TY320履带推土机、D155履带推土机、卡特皮勒履带拖拉机等。液力机械传动应用的普遍传动形式是使用液力变矩器,并利用液力变矩器涡轮具有自动适应外载荷的特点,同时配以较少挡位的行星动 At present, all kinds of wheeled, tracked vehicles commonly used in the walking system in addition to mechanical transmission, but also the widespread use of hydraulic mechanical transmission. Such as TY320 track dozers, D155 track dozers, Caterpillar tracked tractors and more. The common form of transmission used in hydromechanical applications is the use of hydrodynamic torque converters and the use of hydrodynamic torque converters. Turbines have the feature of automatically adapting to external loads and planetary motions with fewer gears
