A crank drive has a frame, which may be formed in particular by a housing, a rocker fixed on the frame, a crank that is fixed on the frame and which forms the drive output, and a coupler which connects the rocker and the crank. The coupler is articulately connected in each case to the crank and to an end, which is situated opposite the positionally fixed mounting, of the rocker. In order to drive the crank, a first cylinder is provided which has a movably mounted piston. The piston and the rocker are articulately connected to one another via a push rod such that the axial movement of the piston sets the rocker in an oscillating swinging motion. The rocker has a section that is remote from the fixed mounting of the rocker and which is inclined by a fixed angle towards the coupler. |
