Embodiment Construction

[0034] The drawings are of a schematic nature and serve only for the understanding of the invention. Identical elements are provided with the same reference numerals.

[0035] exist figure 1 A first exemplary embodiment of a planetary gear 1 according to the invention is shown. The planetary gear 1 is designed as a differential, in particular as a spur differential 2 . It has a planetary carrier 3 which can be referred to as a case, in particular a differential case. The planetary carrier 3 can also be referred to as a planetary carrier.

[0036] A planetary gear set 4 with a first planetary gear 5 and a second planetary gear 6 each is mounted on the planetary carrier 3 via a pin 7 in each case in a bearing sleeve 8 . Planetary gears 5 and 6 are in effective contact with sun gear 9 . In this case, the first planet gears 5 are in active meshing engagement with the first sun gear 10 and the second planet gears 6 are in active meshing contact with the second sun gear 11 . T...

Abstract

The invention relates to a planetary gearbox (1, 43, 47) such as a differential, comprising a planet carrier (3), to which planet wheels (5, 6) that are in functional contact with at least one sun gear (9, 10, 11) are rotatably attached, said planet carrier (3) being connected to a drive wheel (15).

Description

technical field [0001] The present invention relates to a planetary gear transmission, such as a differential, having a planet carrier to which planet wheels are rotatably attached, said planet wheels being in torque-transmitting operative contact with at least one sun gear, Wherein the planet carrier is connected with the drive wheel, such as a spur gear. Background technique [0002] The planetary carrier can also be designed as a differential case. [0003] From the prior art, different planetary gears are already known, eg from EP 0156067 . [0004] In principle, a differential gear for motor vehicles is also known from DE 10156890 C1. There, a differential case for a motor vehicle is disclosed, which has a differential case housing with a drive ring mounted in the housing wall, in which a differential case with The differential pin of at least one rotatably mounted differential bevel gear engages the drive shaft gear of the drive shaft mounted in the differential cas...
