ABSTRACT:
To reduce vibrations and noise, a final drive assembly of a vehicle is supported at four separate support points. The first and fourth support points are on the front side of the axis of a ring gear of a final reduction gear pair, and a second and third support points are on the opposite rear side. The third and fourth support points are on the same side of the axis of a drive pinion of the final reduction gear pair, as the ring gear. The first and second support points are on the opposite side of the axis to the ring gear. The support stiffness is greatest at one of the first and third support points. The support positions and support stiffness are preferably determined according to theoretically obtained mathematical relationships.
