Planetary differential device and method for producing a planetary differential device

A planetary differential device comprising:

• a first and a second sun gear wherein the sun gears are coaxial to one another and define a main axis;
• first and second planet gears wherein the first planet gears mesh with the first sun gear and the second planet gears mesh with the second sun gear, and wherein the first and second planet gears mesh with one another in pairs;
• a planet carrier having two lateral disks, wherein the first and second planet gears are rotatably disposed in the planet carrier;
• and
• a coupling gear coaxial to the main axis and permanently connected to the planet carrier;
• wherein the lateral disks are each materially bonded to the coupling gear and form a receiving housing with a housing interior, wherein at least one of the lateral disks is a lateral installation disk having an installation hole having a diameter that exceeds an outer circumference of the first sun gear and an outer circumference of the second sun gear such that the planet gears and the sun gears are insertable into the housing interior through the installation hole.
