Planetary transmission, in particular for a motor vehicle

A planetary transmission comprising:

• a housing;
• a first collecting groove configured to collect a lubricant;
• a planetary gear set comprising
• a planetary support rotatable around a planetary gear set axis of rotation relative to the housing;
• planetary gears rotatably mounted on the planetary support;
• a ring gear meshing with the planetary gears, wherein the ring gear has a first lubricant channel running radially with respect to the planetary gear set axis of rotation or a cylinder portion connected to the ring gear in a rotationally fixed manner has the first lubricant channel;
• and
• a planetary gear pin connected to the planetary support in a rotationally fixed manner, wherein at least one of the planetary gears is rotatably mounted on the planetary gear pin around a planetary gear axis of rotation, wherein the planetary gear pin has a second lubricant channel running perpendicularly to the planetary gear axis of rotation;
• a second collecting groove connected to the planetary gear pin in a rotationally fixed manner;
• and
• a disc coupling comprising
• an inner disc support connected to the first collecting groove in a rotationally fixed manner and connected to the ring gear in a rotationally fixed manner;
• an outer disc support connected to the housing in a rotationally fixed manner;
• and
• a set of friction discs,
• wherein the planetary gear pin has a blind hole,
• wherein the second collecting groove is arranged adjacently to the blind hole, and
• wherein the second collecting groove is arranged radially inside the first collecting groove and axially at least partially overlapping with the first collecting groove.
