    • A multiple speed ratio hydrokinetic transmission for a wheeled vehicle comprising a planetary gear set (20) having two input torque flow paths and a hydrokinetic torque converter (18) having an impeller element (38) connected to one flow path and a turbine element (40) connected to the other flow path; a friction lockup clutch (164) which, under relatively high speed driving conditions, establishes a mechanical torque bypass path for engine torque in parallel with a torque path established by the hydrokinetic unit (18); and an overrunning coupling (152) located between the friction clutch and the turbine element (40) to adapt the transmission for a direct mechanical torque transfer from the vehicle engine to a driven member or a split torque path that is partly mechanical and partly hydrokinetic; provision being made during high speed ratio operation for a regenerative torque distribution between the input elements through the friction clutch (164) and the overrunning coupling (152) thereby providing improved driveline efficiency and improved driveability for the driveline with reduced harshness in ratio changes.
    • 一种用于轮式车辆的多速比水动力传动装置,其包括具有两个输入扭矩流动路径的行星齿轮组(20)和具有连接到一个流动路径的叶轮元件(38)和涡轮机元件(40)的动力学变矩器(18) )连接到另一个流路; 摩擦锁止离合器(164),其在相对高速的驾驶条件下,与由所述动力学单元(18)建立的转矩路径平行地建立用于发动机扭矩的机械转矩旁路路径; 以及位于所述摩擦离合器和所述涡轮机元件(40)之间的超越联接器(152),以使所述变速器适于从所述车辆发动机到被驱动构件或部分机械和部分水动力的分离转矩路径的直接机械扭矩传递; 通过摩擦离合器(164)和超越联接器(152)在输入元件之间的再生扭矩分配的高速比操作期间进行设置,由此提供更好的传动系效率,并且改善传动系的驾驶性能,同时减小比例变化的粗糙度。
