ABSTRACT:
In order to provide a vehicle with a driven wheel (30), which possesses an external wheel hub (23) and is driven with the aid of a thrust crank drive which, while easily and safely operable, is at the same time able to achieve a high terminal velocity and which is simple in the construction of the drive arrangement, the thrust crank drive comprises a crankwheel (38) and a thrust rod (37) rotatably hinged with one end to the crankwheel (38) outside the wheel axis for the transmission of the force. The driven wheel (30) is driven by means of a drive wheel (7) which, via a free-wheel mechanism (11,12, 13,14,19), is in operative connection with the external wheel hub (23) of the driven wheel (30). A first mechanism (36) is provided which transmits the force between the crankwheel (38) and the drive wheel (7) and, for overcoming the dead center, a second mechanism is provided in the thrust crank drive which at least partially neutralizes the effect of the free-wheel mechanism (11,12,13,14,19).
