Abstract
An automobile has a final reduction gear unit including an orthogonal converter gear train, a speed reducer gear train, and a differential gear train which are mounted on one side of the engine of the automobile. The orthogonal converter gear unit includes a drive bevel gear coupled to a first rotatable shaft for rotation about the axis thereof, and a driven bevel gear mounted on a second rotatable shaft normal to the first rotatable shaft and rotatable about the axis of the second rotatable shaft. The speed reducer gear train includes a drive cylindrical gear mounted on the second rotatable shaft, and a driven cylindrical gear held in mesh with the drive cylindrical gear and mounted on a third shaft for rotation thereabout, the third rotatable shaft lying parallel to the second rotatable shaft. The differential gear train has four bevel gears combined with the driven cylindrical gear for distributing power from the engine of the automobile transmitted to the driven cylindrical gear, to road wheels of the automobile.
