1. A gearing assembly for a drivetrain of a vehicle, comprising:
a first shaft rotating about a first shaft axis;
a second shaft operatively connected to the first shaft, the second shaft rotating about a second shaft axis extending parallel to the first shaft axis;
a first gear mounted to the first shaft, the first gear being a freewheel clutch gear;
a second gear fixedly mounted to the first shaft for rotation therewith;
a third gear mounted to the second shaft, the third gear being a freewheel clutch gear, the third gear being drivingly engaged with the second gear; and
a fourth gear fixedly mounted to the second shaft for rotation therewith, the fourth gear being drivingly engaged with the first gear,
wherein:
when a rotational speed of the first shaft is greater than a rotational speed of the second shaft, the first shaft drives the second shaft via driving engagement between the second gear and the third gear, the first gear being overrun; and
when the rotational speed of the second shaft is greater than the rotational speed of the first shaft, the second shaft drives the first shaft via driving engagement between the fourth gear and the first gear, the third gear being overrun.
