A gear driven by wobble movement contains an ergonomic pendulum (D), a centric disk (C) and a flywheel (A) having a common axis (S) of rotation. In the axis (S) of rotation a shaft (H) is placed which is joined to the pendulum (D). The mutual concentric position of the centric disk (C) and the flywheel (A) is delimitated by planet disk (B) which contacts the periphery of the centric disk (C) and the internal periphery of the flywheel (A) and is joined rotatably to the supporting structure (T). The supporting structure (T) is fixed to the linked structure which fixes the supporting structure (T), together with the planet disk (B), against rotation with respect to the axis (S) of rotation. A first freewheel (V1) is situated between the shaft (H) and flywheel (A) and a second freewheel (V2) is situated between the shaft (H) and centric disc (C).

The present invention relates to a combustion engine which includes at least one crankshaft rotating about a first rotation shaft; at least one output shaft outputting an engine torque, said output shaft rotating about a second rotation shaft separate from said first rotation shaft; at least one transmission assembly rotating about said first rotation shaft and being rotated by said crankshaft in order to transmit said engine torque to said output shaft.
