ⁿ Spur gear equalization gear, especially for motor vehicles

Oils invention looks eloh on a spur gear, Particularly for motor vehicles, in which a ring gear mounted in a common external gear housing housing is rotationally connected to a drive half-shaft and planet gears mounted on a planet carrier are in engagement with the ring gears stand·

In a known differential gear of the same type, the internal and external durometers are identical in each case Ring gears as a result of profl-tereohifting under soleedlioh · Zühne-Btihlen on t where the ring gears of the drive half-shafts and a «Ueätiliohee, Drehfeit alt de« Aueglelohgetriebegehäuae Ttrbundenee ring gear jewelle geaielneeji with a planet gear in Engagement stand.

The different internal gear as well as the here division of the old profile reworking presented here mean a considerable increase in the price of the differential gears. Due to the fact that three internal gears each have a planetary gear, this results in a disadvantageous structural and circular length of teeth "ahluntereohied the ring gears and daait dl" auegl · ichbare Differensdrehsanl is small as a result of moving around execution τοπ Auüen- and Innendurohneeeern, eo that a eehter Auegleich tone Drehsahldifferensen not aöglioh let *
