BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a drive device for a rotating part, in particular a vehicle axle.
Modern bicycles and other similar devices which are driven by human force are customarily moved by rotating drive elements.
SUMMARY OF THE INVENTION
The required drive energy must always be made available by man, corresponding to what is required at the time.
The present invention represents pulse drives of digital character which permit a direct drive with physical force in the form of mechanical pulses, store energy surpluses fed in, and, as a force amplifier, makes them available as needed.
Such a drive device is characterized by the features disclosed and claimed herewith.

DETAILED DESCRIPTION
One embodiment of a drive pedal of a bicycle with complex functions is shown in FIG. 1. The lever 4, which is pivotally suspended on pivot point 2 on the frame 1 and held by a spring 3 as well as a stop, has the following functions: By foul pressure applied in the direction of arrow 5 to pedal 16 supported by pump cell 6, the lever 4 is moved in direction 7, whereupon the active wedge 9 guided by rollers 8 within the lever 4 moves, in opposition to return compression spring 10, in the direction 12 and, at the same time, the friction wheel 13 and the wheel 14 which is rigidly coupled to it move in the direction of arrow 15.
Upon the release of the lever 4 from load, it is brought to the initial position by spring 3 and the wedge 9 is moved back into its initial position by spring 10.
The manner of operation described above corresponds to the direct tangential-force pulse-drive with the active H-STEP wedge.
The pump cell 6 which is present below the pedal 16 serves to divert a part of the drive energy, to pressure accumulator 17 which can be connected as required, via control valve 19 and pressure regulator 20, to force cell 18 which acts as a force amplifier.
In this way, it is possible to impart to a bicycle, particularly in city traffic, an ability to accelerate as a result of which when a traffic control si
