Problems solved by technology

[0004] Although the improvements offered by the Schaeffler differential allow for a reduced differential size relative to the original spur gear differential, however due to the use of a very negative addendum correction, one of the two gear meshes intensity is severely reduced

Abstract

A Parallel axis epicyclic gear differential comprises first and second sun gears connected with first and second output driving shafts, at least one planetary gear set and a differential mechanism housing. The first and second sun gear s and the planetary gear set are arranged in the differential mechanism housing. Each planetary gear set comprises a first planetary gear connected with the first gear set and the second gear set connected with the second planetary gear and a third gear. The first planetary gear is engaged with the first sun gear and is not engaged with the second sun gear, the second planetary gear is engaged with the second sun gear and is not engaged with the first sun gear, and the third planetary gear is ridily fixed to the second planetary gear, wherein the third planetary gear is engaged with the first planetary gear and is not engaged with the first and second sun gears.

Description

technical field [0001] The present invention relates generally to vehicles, and more particularly, to compact, lightweight, easily manufactured, parallel axis planetary differentials. Background technique [0002] Modern cars use any of several different types of differentials, one of which is a spur differential. The original spur gear differential that was the subject of US Patent No. 691,591 was designed to provide an alternative to the bevel gear differential. In the spur gear differential disclosed in the '591 patent, a pair of sun gears, preferably spur gears, are connected to left and right output shafts. The disclosed differential also includes pairs of planet gears arranged around the circumference of the sun gear, wherein one planet gear of each pair is connected to one of the sun gears and the second planet gear of each pair is connected to the first sun gear. Two central gears. The individual planet gears in each pair are designed to mesh together. Input powe...
