IMPROVED TIMING OF MULTIPLE GEAR TRAIN DIFFERENTIAL A differential gear assembly of the type used in automotive and truck axles having multiple gear trains for interconnecting axle ends is provided with gearing components having a particular relationship between tooth numbers for simplifying assembly requirements of the differential. For example, each gear train includes a pair of combination gears (40, 50) formed with center worm wheel portions (42, 52) and first (44, 54) and second (46, 56) spur portions at either end. The tooth numbers of the spur portions (44, 54 and 46, 56) are made an integer multiple of the tooth numbers of the worm wheel portions (42, 52) of each combination gear (40, 50). This enables the respective gear trains to be assembled in a properly timed relationship at an expanded number of easily recognizable rotational positions. |
