Embodiment Construction

[0034] exist figure 1 A first embodiment of a planetary gear 1 according to the invention is shown in . The planetary gear 1 is designed as a differential, in particular as a spur differential 2 . The planetary gear has a planetary carrier 3 which can be referred to as a box, in particular as a differential box. The planetary carrier 3 can also be referred to as a planetary carrier.

[0035] A planetary gear set 4 , each having a first planetary gear 5 and a second planetary gear 6 , is mounted on the planetary carrier 3 via each pin 7 , which pins are located 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 wheels 6 are in active meshing contact with the second sun gear 11 . The pin 7 is designed as a hollow pin. The planet wheels 5 and 6 of the planetary gear set 4 can be brought into mesh with each other.

Abstract

The invention relates to a planetary gear (1), such as a differential, having a planet carrier (3) on which planet wheels (5, 6) are rotatably attached, The planet gears are in mesh with at least one sun gear (9, 10, 11), wherein the planet carrier (3) is connected to a drive wheel (15), for example to a spur gear (16); radially and / or axially A bearing (19), such as a rolling bearing (20), which determines the position of the planet carrier (3), has two bearing rings, such as an inner bearing ring (29) and an outer bearing ring (28), wherein the planet carrier ( 3) and / or the bearing ring has a flange (31) oriented axially in the direction of the sun gear (9).

Description

technical field [0001] The invention relates to a planetary gear, such as a differential, having a planet carrier to which planet wheels are attached in a rotatable manner, said planet wheels meshingly engaged with at least one sun gear , wherein the planetary carrier is connected to a drive wheel, such as a spur gear, and the planetary gear transmission also has a bearing, such as a rolling bearing, that radially and / or axially determines the position of the planetary carrier, the bearing having two bearing rings, For example a bearing inner ring and a bearing outer ring. Background technique [0002] The planetary carrier can also be referred to as a box, in particular it can be formed as a differential box. [0003] Various planetary gears are known from the prior art, for example from EP 0156067 . [0004] In principle, a differential gearbox for a motor vehicle is also known from DE 10156890 C1. There, a differential case for a motor vehicle is disclosed, which has a...
