ABSTRACT:
Drive gear system for motor vehicles. The invention is particularly applicable to driving means such as planetary gearing for connecting multiple electric motors respectively to individual wheels of such vehicle. Recognizing that differing demands are made upon various parts of such mechanism, such as the braking disk, the wheel rim supporting disk and other component parts of the drive system, it is expensive and inconvenient to make the entire unit of material capable of meeting the most severe conditions imposed upon any part thereof. Accordingly, there is here provided a construction by which the braking disk, the wheel rim supporting disk, ring gear, supporting housing and other component parts may all be made as units separate from each other and therefore made as desired of materials appropriate to their respective functions. Further, the braking disk and support structure therefor are excepting for a small centering land mounted in a manner to be spaced from adjacent components whereby to minimize heat transfer and resulting distortion.
