ABSTRACT:
Planetary gearing for vehicles such as earth-moving loaders gives a plurality of forward ratios and a plurality of reverse ratios each approximately equal to one of the forward ratios. The gearing has four planetary gear sets with input clutches selectively driving sun gears of the first and second sets. The output is connected to the planet carrier of the first set and to sun or ring gears of the third and fourth sets. One other element of the third set is connected to one other element of the fourth set and to releasable holding means. The remaining element of the fourth set is connected to the annulus of the first set of the planet carrier of the second set.
