Automatic transmission meanly use hydraulic torque converter and planetary gear-box, which is called hydraulic automatic transmission ( AT ). 现代自动变速器主要采用液力变矩器与行星齿轮变速箱相结合的液力机械自动变速器(AT)。
According to the characteristics of off-road vehicle automated mechanical transmission ( AMT ) and the control principle of the torque converter slip and lock-up clutch, the hydraulic control system of the shift, slip and lock-up is designed, the slip and lock-up control district is determined. 根据越野汽车机械自动变速系统的特点和液力变矩器滑差与闭锁离合器的控制原理,设计了换挡、滑差和闭锁液压控制系统,并确定了滑差和闭锁控制区域。
Hydraulic transmission shunting locomotives have many characteristics, such as high working efficiency, good economy performance, simple operation and maintenance. Hydraulic torque converter is the key of determining performance of hydraulic transmission locomotives. 液力传动调车机车具有作业效率高,经济性好,操作及维护简单等特点,液力变矩器是决定液力传动机车性能的关键。
