Embodiment Construction

[0061] exist figure 1 A first embodiment of the transfer case transmission 1 according to the invention is shown in . The splitter gear 1 has a first planetary gear 2 and an additional superposition gear 3 . The first planetary gear 2 is designed as a spur gear differential and has a first sun gear 4 and a second sun gear 5 . The sun gears engage in each case with at least one planet gear 6 , which is rotatably mounted on the planet carrier 7 via at least one bolt. In each case two planetary gears 6 mesh with each other, so that torque passes from the first sun gear via the planetary gears 6 to the other planetary gear 6 and then to the second sun gear 5 . The planetary carrier 7 can also be configured as a parking lock wheel 8 and have a parking toothing 9 on its outer side.

[0062] A bell 10 with an axially protruding pin 11 can be inserted into the first sun gear 4 . The at least partially hollow shaft 12 can be inserted into the second sun gear 5 .

[0063] At its su...

Abstract

The present invention relates to a transfer case transmission mechanism (1) possessing at least one first planetary transmission mechanism (2) and a superposition transmission mechanism (3) connected with the first planetary transmission mechanism in a torque transmission manner, wherein the first planetary transmission mechanism (2) possesses a planetary support (7), and the superposition transmission mechanism (3) possesses a gear (19) adjacent to the planetary support (7) in an axial direction. The gear (19) supports an axial end part (13) of the planetary support (7) at the side of the superposition transmission mechanism (3) via an adjusting sheet (33) of which the thickness can be adjusted and an axial rolling bearing unit (18). According to the present invention, the transfer case transmission mechanism is wear resistant, and especially causes less noise emission.

Description

technical field [0001] The invention relates to a splitter gear having at least one first planetary gear and a superposition gear connected in a torque-transmitting manner to the first planetary gear, wherein the first planetary gear has a planetary carrier, and The superposition gear has a toothed wheel axially adjacent to the planetary carrier. Background technique [0002] A planetary gear for transmitting drive torque in a vehicle and a drive unit with such a planetary gear are known from the prior art. For example, DE 10 2010 036 243 A1 discloses such a device and the task set forth is to provide a planetary gear and a drive unit having the planetary gear, which are characterized by very good integration capabilities. To this end, the printed document discloses a planetary transmission for transmitting drive torque in a vehicle, which has a first sun gear set and a second sun gear set, wherein each of these sun gear sets is The shafts are coupled in a rotationally fix...
