Embodiment Construction

[0018] according to figure 1 , the planetary stage with integrated spur gear differential comprises two planetary gearsets 1 and 2 arranged axially side by side, said planetary gearsets are each mounted rotationally via a planetary pin, that is to say to one side via each The associated bores 3 a , 3 b are (for example) rotatably mounted on a common central carrier plate 4 of the planetary carrier 5 , which encloses the first planetary gear set 1 in a cage-like manner.

[0019] Overall, the first planetary gearset 1 has (for example) five planetary gears 6 arranged equidistantly from one another on the same circumference of the planetary gear carrier 5 , which form planetary stages.

[0020] In contrast, the second planetary gearset 2 is formed from a total of three planetary gear pairs 7 of different diameters (for example) in tooth meshing with one another for forming a differential stage.

[0021] One planet gear 8 of each planet gear pair 7 interacts with a first sun gear...

Abstract

The invention relates to a planetary gear transmission with at least two planetary gear sets (1, 2) arranged axially next to each other, which are rotatably mounted via separate planet pin shafts assigned to each other, the planetary gear sets (1, 2) The pins are mounted on one side via the respective associated holes (3a, 3b; 3a', 3b'; 3a", 3b"; 13a-13e) on the common central carrier plate (4) of the planet carrier (5). , wherein in the hole pattern of the central carrier plate (4), the holes (13a-13e) of the first planetary gear set (1) provided for the installation of the planetary pin shafts and the second planetary gears arranged axially beside it The bores (3a, 3b; 3a', 3b'; 3a", 3b") of the planetary pins of the gear set (2) partially overlap.

Description

technical field [0001] The invention relates to a planetary gear with at least two planetary gear sets arranged axially next to each other, which are mounted in rotation via respective associated individual planetary pins, said planetary pins being on one side. They are mounted on a common carrier plate of the planetary carrier via the respective associated holes. [0002] The field of application of the invention extends mainly to motor vehicle technology. In particular, in motor vehicles with all-wheel drive the spur gear differential is integrated into the planetary stage in order to structurally combine the axle differential with the center axle differential in order to form a transfer case, so The transfer case described above requires a small amount of installation space in the axial direction with a low weight. Background technique [0003] Such a transfer case is known from DE 10 2008 027 992 A1, in which the planet wheels of one planetary gear set and the planet w...
