Abstract (en)

[origin: WO2011006683A1] The invention relates to a crank drive, having a frame, which may be formed in particular by a housing, having a rocker (1) positionally fixedly mounted on the frame, having a crank (3) which is positionally fixedly mounted on the frame and which forms the drive output, and having a coupler (5) which connects the rocker (1) and the crank (3), wherein the coupler (5) is articulatedly connected in each case to the crank (3) and to an end, which is situated opposite the positionally fixed mounting (2), of the rocker (1), wherein to drive the crank (3), a first cylinder (12) is provided which has a movably mounted piston (13), wherein the piston (13) and the rocker (1) are articulatedly connected to one another via a push rod (14) such that the axial movement of the piston (13) sets the rocker (1) in an oscillating swinging motion, and wherein the rocker (1) comprises a section (8) which is remote from the positionally fixed mounting of the rocker (1) and which is inclined by a fixed angle towards the coupler (5).
