Abstract
A drive arrangement for a pedelec comprises a manual drive shaft (1), an output shaft (2) for driving a wheel of the pedelec, a first electric drive (EM1) that drives a first rotor shaft, and a second electric drive (EM2) that drives a second rotor shaft, as well as a transmission with a superposition function comprising at least one planetary gear set (PS1, PS2, PS3), the transmission ratio of which is continuously adjustable by means of the first and second electric drives (EM1, EM2) and through which the manual drive shaft (1) and the output shaft (2) are coupled to each other. A torque generated by the second electric drive (EM2) can be transmitted at least partially to the output shaft (2) by transmitting a rotation of the second rotor shaft via at least one gear stage (ST) to a ring gear (HR1) of a first planetary gear set (PS1) of the transmission.The first rotor shaft of the first electric drive (EM1) runs coaxially to a rotational axis of a sun gear (SR1) of the first planetary gear set (PS1). A pedelec is also proposed.
