Abstract

804,775. Motor vehicle driving gear. GLEASMAN, V. E. March 21, 1956, No. 8801/56. Class 79(2) [Also in Group XXIV] In a differential gear the casing 30 rotated by a gear 32 has pairs of worm wheels 60 mounted therein. The worm wheels of each pair carry imtermeshing spur gears 61 and gear with worms 70 fixed to the wheel axles 75. The diameter of the worms 70 is greater than that of the worm wheels. This arrangement ensures equal driving power to be transmitted to the wheel axles and prevents wheel spinning. Unequal power may be transmitted to the wheel axles by making the spur gears 61 of differing sizes or by giving the worms 70 different lead angles. As applied to a vehicle, forward and rear axle shafts 90,. 113, Fig. 10, are driven through differentials 91, 112. Differential 91 is driven from one output member of a differential 101 through gearing 92...95 and the other differential 112 is driven from the other output member 103 of the differential 101 through a universal joint 104 and gearing 107 ...110. Thus the power may be distributed between the axles either equally or unequally according to the type of differential fitted.
