The invention relates to an electric drive (1; 11; 21; 31), comprising an arranged transmission (4). The transmission (4) comprises at least one planetary gear set comprising at least three rotational elements (12; r, SR, PT, HR). The electric drive (1; 11; 21; 31) further comprises an electric motor (5) which is offset relative to the transmission (4); the drive shaft (7; 7 ') mounted at least on a pedal crankshaft (6) of the bicycle; a drive wheel (8) arranged coaxially with respect to the drive shaft (7) for transmitting motor power of the electric motor (5) to the drive shaft (7; 7 '); a first flywheel element (F1); and a second flywheel element (F2). The first flywheel element (F1) and the second flywheel element (F2) are arranged together in a one-piece flywheel element carrier (9). The drive wheel (8) can be connected to the drive shaft (7; 7 ') by means of a first flywheel element (F1) via a one-piece flywheel element carrier (9). The force transmission device (7, 7 ', 9) of the transmission device (4) comprises a force transmission device (7, 7'), and one of the rotation elements (12, SR, PT, HR) of the planetary gear set of the transmission device (4) can be connected to the drive shaft (7, 7 ') by means of the second flywheel element (F2) via the one-piece flywheel element carrier (9). The other of the rotation elements (12, SR, PT, HR) of the planetary gear set of the transmission device (4) is integrally formed with the force transmission device (7, 7', 9) of the transmission device (4).

    本发明涉及一种用于自行车的电驱动装置(1;11;21;31),包括布置的传动装置(4)。传动装置(4)包括至少一个行星齿轮组,其包括能够相对于彼此旋转的至少三个旋转元件(12;SR、PT、HR)。所述电驱动装置(1;11;21;31)还包括电动马达(5),电动马达相对于传动装置(4)偏移;驱动轴(7;7’),驱动轴被至少安装在自行车的踏板曲柄轴(6)上;驱动轮(8),驱动轮相对于驱动轴(7)同轴布置,用于将电动马达(5)的马达动力传递至驱动轴(7;7’);第一飞轮元件(F1);以及第二飞轮元件(F2)。第一飞轮元件(F1)和第二飞轮元件(F2)一起布置在一体式飞轮元件托架(9)中。驱动轮(8)能够经由一体式飞轮元件托架(9)借助于第一飞轮元件(F1)连接到驱动轴(7;7’),并且传动装置(4)的行星齿轮组的旋转元件(12;SR、PT、HR)中的一个旋转元件能够经由一体式飞轮元件托架(9)借助于第二飞轮元件(F2)连接到驱动轴(7;7’)。传动装置(4)的行星齿轮组的旋转元件(12;SR、PT、HR)中的另一个旋转元件与传动装置(4)的力传递装置(7;7’;9)一体形成。
