Abstract

A device for ventilating a transmission includes a first component configured for fixed arrangement on the transmission and a second component configured for movable arrangement on an outer side of a transmission housing of the transmission. The first and second components are connected to one another by a joint which permits a movement of the first and second components relative to one another. A pipeline extends along the first and second components and has first and second ends for an air exchange, with the first end of the pipeline arranged on the first component and with the second end of the pipeline arranged on the second component. The second component has a center of gravity which is located opposite to the second end of the pipeline in relation to a connecting point between the joint and the second component.
