Driving device for a the electric bicycle, the electric bicycle with drive device and method for braking a vehicle wheel

摘要

A the electric bicycle (2) has a 1 (4) and an electrical drive device (1) with an electric motor (3), via a drive train (15) with a wheel (7) of the electric motor vehicle wheel (2) is connected for the transmission of torques. The electric motor (3), with the aid of an operating element (14) of a motor operation are switched over into a generator mode, in order on the one hand the electric bicycle (2) and, on the other hand, to brake the vehicle during the braking of the electronic wheel (2) of the electric motor (3) produced braking current to charge an accumulator (30) of the electric motor vehicle wheel (2) to use. The operating element (14) is in this case as a of a steering rod (16) of the electric motor vehicle wheel (2), in the operating position, the assembled links - or bicycle bar grip (17) is formed, which a rotatably mounted switching element (18) with a signal generator (22) comprises. For the brakes of the electric motor vehicle wheel (2) with the aid of the electric motor (3), the switching element (18) on the handlebar grip (17) about the longitudinal axis (m1) of the guide handle (17) from its initial position in the direction of arrow pf1 rotated, as a result of which also the signal transmitter (22) in the operating element (14) is displaced and a control signal which control signal a control - and regulating device (13) of the drive device (1) for switching over of the electric motor (3) is fed into the generator mode. The of the electric motor (3) produced during braking braking current can then the storage battery (30) are supplied to the charging and the range of the electric motor vehicle wheel (2) to increase.
