1. A transmission (1) for an integral differential (10), comprising:
a fixed housing part (9);
a first planetary gear set (6) defining an axis of rotation, the first planetary gear set (6) comprising:
a planet carrier (2) fixed to the fixed housing part (9) to seal a lubricant chamber (8) spatially delimited by the planet carrier (2) and the fixed housing part (9), at least a portion of the lubricant chamber (8) extending around the axis of rotation;
planetary bearings (7), the planetary bearings (7) being supplied with lubricant from the lubricant chamber (8);
planet gears (3), each of the planet gears (3) being rotatably mounted on the planet carrier (2) via at least one respective bearing of the planetary bearings (7);
a sun gear (4) meshing with the planet gears (3); and
a ring gear (5) meshing with the planet gears (3); and
a sealing element (24) between the planet carrier (2) and the fixed housing part (9), the sealing element (24) further sealing the lubricant chamber (8).
