The invention relates to a torque transmission unit (15) and a drive train (10), the torque transmission unit (15) comprising a first input side (35), a second input side (40), an output side (45), a hydrodynamic converter (65) and a lock-up clutch (70), the first input side (35) can be connected in a torque-transmitting manner to an internal combustion engine (20) and a first torque (M1) can be introduced to the first input side (35), the torque-transmitting unit (15) having a freewheel (75), in a torque flow of the first torque (M1) from the first input side (35) to the output side (45), the first input side (35) is connected to the internal combustion engine (20) in a torque-transmitting manner and the first torque (M1) can be introduced to the free wheel (75). The freewheel (75) is arranged downstream of the hydrodynamic converter (65) and the second input side (40) is arranged downstream of the freewheel (75), the freewheel (75) being designed in such a way that the hydrodynamic converter (65) is connected in a torque-transmitting manner to the output side (45) in a first freewheel operating state, and the freewheel (75) being designed in such a way that the hydrodynamic converter (65) is connected in a torque-transmitting manner to the output side (45) in a second freewheel operating state. The freewheel (75) is designed in such a way that, in a second freewheel operating state, the hydrodynamic converter is decoupled from the output side (45), and wherein the freewheel (75) is designed in such a way that the hydrodynamic converter is decoupled from the output side (45) when the lock-up clutch (70) is open, and wherein the first torque (M1) is transmitted from the first input side (35) to the output side (45) when the lock-up clutch (70) is closed. In order to at least partially prevent the transmission of a second torque (M2) from the second input side (40) to the hydrodynamic converter (65).

    本发明涉及一种扭矩传递单元(15)和传动系(10),其中,所述扭矩传递单元(15)包括第一输入侧(35)、第二输入侧(40)、输出侧(45)、液力转换器(65)以及锁止离合器(70),其中,所述第一输入侧(35)能够以扭矩传递的方式连接至内燃发动机(20)并且第一扭矩(M1)能够被引入到所述第一输入侧(35),其中,所述扭矩传递单元(15)具有自由轮(75),其中,在所述第一扭矩(M1)的从所述第一输入侧(35)到所述输出侧(45)的扭矩流中,所述自由轮(75)布置在所述液力转换器(65)的下游并且所述第二输入侧(40)布置在所述自由轮(75)的下游,其中,所述自由轮(75)被设计成使得在第一自由轮操作状态下将所述液力转换器(65)以扭矩传递的方式连接至所述输出侧(45),以用于在所述锁止离合器(70)打开时将所述第一扭矩(M1)从所述第一输入侧(35)传递至所述输出侧(45),并且其中,所述自由轮(75)被设计成使得在第二自由轮操作状态下将所述液力转换器与所述输出侧(45)断开联接,以至少部分地阻止第二扭矩(M2)的从所述第二输入侧(40)到所述液力转换器(65)的传递。
