1. A lubricant device configured for supplying lubricant to a planetary carrier of a planetary gearset having a planetary carrier defining an opening the lubricant device comprising:
at least one planetary bolt which passes through and extends beyond the openingin the planetary carrier so that at a front end of the at least one planetary bolt has an axially projecting end area;
a collecting tray configured for guiding lubricant which, in an operating condition, flows along the collecting tray to the at least one planetary bolt; and
an annular intermediate element which, in an assembled condition, is fixed axially onto the collecting tray facing in a direction of the planetary carrier, wherein the annular intermediate element has a first radial projection and a separate second radial projection a distance away in the axial direction,
and wherein the planetary bolt has at its axially projecting end area a corresponding first fixing contour and a second fixing contour a distance away in the axial direction, in order to latch the first radial projection of the annular intermediate element into the first fixing contour to produce an arrangement secure against rotation and in order to latch the second radial projection into the second fixing contour to produce an axially secure arrangement of the collecting tray and the planetary bolt.
