A vehicle that is operable by motor power and/or by muscular power, in particular an electric bicycle, including a crankshaft drive having a bottom bracket bearing shaft, a front sprocket that transmits a drive torque for the vehicle to a chain, an electric drive and a friction gear for continuously varying a transmission ratio, the friction gear and the electric drive being configured on the crankshaft drive, and the friction gear being coupled to the crankshaft drive and adapted for transmitting a rider-produced torque to the front sprocket.

Vehicle operable by motor power and by muscular power

A vehicle is provided which is operable to motor power and/or pedal power, in particular an electric bicycle, which includes a crankshaft drive having a bottom bracket spindle, a chain ring, which outputs a drive torque for the vehicle to a chain, an electric drive, and a cone ring transmission for the continuous variation of a gear step ratio, the cone ring transmission and the electric drive being situated at the crankshaft drive, and the cone ring transmission being connected to the crankshaft drive and set up in such a way that a torque generated by the rider is transmitted to the chain ring.

Vehicle operable by motor and by muscular energy

The invention relates to a load torque lock () comprising a sling element () that frictionally interacts with a brake component () for blocking a torque, and a drive wheel () that is coupled in a torque transferring manner to a carrier () having at least one contact area () to the sling element () and engaging axially in the drive wheel (), by means of which a torque to be blocked can be initiated in the sling element (). According to the invention, the carrier () has means for reducing the bending tension in the at least one contact region ().

Load torque lock and apparatus having load torque lock

A permanent magnet-excited electric motor with a rotating rotor having permanent magnets disposed with alternating polarities in a ring around its circumference, which magnets cooperate with coils of a stator encompassing the rotor. The permanent magnets, as individual magnets next to one another that are distributed uniformly over the circumference of the rotor, rest on an annular support and are clamped in place at their axial ends by a respective annular frame made of magnetically inactive material.
