• The idle gear is engaged with the front differential sun gear. The idle gear is spline engaged with the ring gear shaft and the ring gear is spline engaged with the ring gear shaft, so that when the front differential rotates, the idle and ring gears rotate as a single unit.
• Since the ring gear is engaged to the drive pinion, when the ring gear rotates, the force direction is changed to 90 ° to transmit it to the drive pinion, and then to the rear tires via the propeller shaft and rear differential.
