Abstract

The present invention provides a drive assembly (80) for a vehicle (1) which can be driven with engine power and in particular additionally with muscle power, an electric bicycle, eBike or pedelec, the drive assembly has an electric drive (3) for generating an engine torque, a crankshaft (15) rotatable around an axis of rotation (Y) for receiving at least the engine torque, a transmission device (20) designed to transmit a torque from the crankshaft (15) to a driven element (4) that can be coupled to a drive wheel (9-2) of the vehicle (1), the transmission device being designed to create a shiftable variable transmission ratio, and an adjusting device (60) which is coupled to the transmission device (20) and via the actuation of which the transmission ratio of the transmission device (20)can be adjusted, wherein the electric drive (3) is designed to actuate the adjusting device (60) and can be coupled to the adjusting device (60), in particular to transmit at least some of the enginetorque.

Description

technical field [0001] The invention relates to a drive assembly and a vehicle. In particular, the present invention relates to a drive assembly for a vehicle, an electric bicycle, an electric self-propelled bicycle, an electric power-assisted bicycle, and a drive assembly capable of being driven by a motor force and, if necessary, additionally by muscle power. Such vehicles that can be driven by muscle power, especially electric bicycles, electric self-propelled bicycles, and electric power-assisted bicycles. Background technique [0002] Typically, bicycles, electric bicycles, etc. are constructed with chain-type shifters or hub-type shifters at the driven rear wheels. As an alternative thereto, a pedal bearing drive with an integrated gearshift can also be provided. [0003] A problem with the known drive unit with the shifting gear arranged on the pedal bearing is that the drive unit is increased in size, and in the case of a motor-driven shifting mechanism it is furth...
