The invention relates to an electric bicycle drive unit (DU) for being arranged coaxially with a bottom bracket in a bottom bracket region of a bicycle frame. Said drive unit (DU) comprises a torque sensor device (ST) for measuring the total torque (TR) of the rider, a bottom support shaft (SB), an electric motor device (ME) arranged coaxially to the bottom support shaft (SB), an output hollow shaft (SO) for transmitting the motor torque (TM) and the rider torque (TR) to the bicycle drive train, and a method for transmitting the rider torque (TR) from the bottom support shaft (SB) a rider torque coupling device (DCR) coupled to the output hollow shaft (SO) and a motor torque coupling device (DCM) for coupling a motor torque (TM) to the output hollow shaft (SO). The torque sensor device (ST) is arranged in an axial region (PA) of the drive unit defined by the output hollow shaft section (SOS), wherein the axial region (PA) is provided for transmitting a rider torque (TR) and a motor torque (TM).
本发明涉及一种用于与底部支架同轴地布置在自行车车架的底部支架区域中的电动自行车驱动单元(DU)。所述驱动单元(DU)包括用于测量骑行者总转矩(TR)的转矩传感器装置(ST)、底部支架轴(SB)、与底部支架轴(SB)同轴地布置的电动马达装置(ME)、用于将马达转矩(TM)和骑行者转矩(TR)传递到自行车传动系上的输出空心轴(SO)以及用于将骑行者转矩(TR)从底部支架轴(SB)耦合到输出空心轴(SO)上的骑行者力矩耦合装置(DCR)和用于将马达转矩(TM)耦合到输出空心轴(SO)上的马达力矩耦合装置(DCM)。转矩传感器装置(ST)布置在驱动单元的由输出空心轴区段(SOS)限定的轴向区域(PA)中,其中轴向区域(PA)设置用于传递骑行者转矩(TR)和马达转矩(TM)。
