Abstract:
A transmission includes at least one planetary gear stage with a planet carrier having a first toothing. The transmission further includes at least one lubricant line having a first outlet opening and a second outlet opening. The first toothing, together with a second toothing, forms a spline. The first outlet opening is configured to lubricate the spline, and the second outlet opening is configured to lubricate a sun gear of the planetary gear stage.
