摘要： A drive unit (10) for a manually driven vehicle, in particular a bicycle or an EPAC, includes a housing (12), an electric motor (18) with a stator (44) and a rotor (46), a stator support (48), and an electronic unit (50). The stator support (48), the stator (44), the rotor (46), and the electronic unit (50) are designed in the form of one unit (56), which can be preassembled so that the preassembled unit (56) is installable into the housing (12).

摘要： A drive unit (10) for a manually driven vehicle, in particular a bicycle or an EPAC, includes a housing (12), an electric motor (18) with a rotor (44), a bottom bracket shaft (14), a harmonic drive (20) coupled to the rotor (44), and an output shaft (22). The harmonic drive (20) includes an outer bushing with an inner toothing. The outer bushing (38) of the harmonic drive (20) is coupled to the housing (12) via a buffer (64).

摘要： A drive unit (10) for a manually driven vehicle, in particular a bicycle or an EPAC, includes a housing (12), a bottom bracket shaft (14), an electric auxiliary drive (16), and an output shaft (22) designed as a hollow shaft. The bottom bracket shaft (14) and the output shaft (22) are coaxial. The output shaft (22) surrounds the bottom bracket shaft (14) at least partially along an axial direction. A first freewheel clutch (24) and a second freewheel clutch (26) are arranged radially between the bottom bracket shaft (14) and the output shaft (22). The freewheel clutches are axially adjacent and act on the output shaft (22).
