The proposed solution relates to a drive unit (A) for an electric bicycle, comprising: at least one driven shaft (2); a drive shaft (1) rotatable about a drive rotational axis (D1) for generating a first drive torque by means of muscle force manipulation by a rider of the electric bicycle; an electric motor (E) for generating a second drive torque on a rotor shaft (3) coupled to the electric motor (E) by external force actuation; and a transmission device (4, 5) having at least one planetary transmission (5) for transmitting the first and second drive torques to the output shaft (2). In the proposed drive unit (A), the rotor shaft (3) and the output shaft (2) are arranged coaxially to one another, and the drive rotational axis (D1) runs parallel to the rotor shaft (3) and the output shaft (2).

    所提出的解决方案涉及用于电动自行车的驱动单元(A),该驱动单元具有:至少一个从动轴(2);能绕驱动转动轴线(D1)转动的驱动轴(1),其用于由电动自行车的骑行者通过肌肉力操纵来产生第一驱动转矩;电动马达(E),其用于在与电动马达(E)耦联的转子轴(3)上通过外动力操纵来产生第二驱动转矩;以及具有至少一个行星传动机构(5)的传动装置(4、5),其用于将第一和第二驱动转矩传递给从动轴(2)。在所提出的驱动单元(A)中,转子轴(3)和从动轴(2)彼此同轴布置,并且驱动转动轴线(D1)平行于转子轴(3)和从动轴(2)地延伸。
