Abstract

A planetary differential device includes first and second sun gears coaxially arranged in relation to each other and defining a main axis. First and second planetary gears mesh with the first and second sun gears and mesh with each other in pairs. A planet carrier has two side disks, and the planetary gears are rotatably arranged in the planet carrier. A coupling gear is arranged coaxially to the main axis and is rigidly connected to the planet carrier. The side disks are respectively connected to the coupling gear in a material fit and form a receiving housing with a housing inner space, at least one of the side disks includes an assembly opening through which the planetary gears and the sun gears can be inserted into the inner space of the housing.
