Abstract

A transmission housing includes a first housing half forming a first sealing surface and a first lubricant line, and a second housing half forming a second sealing surface and a second lubricant line. The first sealing surface and the second sealing surface seal an internal space in relation to an environment. An opening of the first lubricant line and an opening of the second lubricant line are fluidically connected to one another. The first sealing surface has a first groove and the second sealing surface has a second groove. The first groove and the second groove together form a third lubricant line. The third lubricant line runs between the opening of the first lubricant line into the first sealing surface and the environment of the transmission housing and between the opening of the second lubricant line into the second sealing surface and the environment of the transmission housing.
