Abstract

A drive train unit (HY, G) for a motor vehicle includes a first shaft (TW), a second shaft (PW), and a third shaft (AN). The first shaft (TW) is rotatably mounted at an inner diameter of the second shaft (PW) with a first bearing (L1). The second shaft (PW) is rotatably mounted at an inner diameter of the third shaft (AN) with a second bearing (L2, L2x). A lube oil feed to the first bearing (L1) and the second bearing (L2, L2x) takes place through a bore hole (B1) arranged in the first shaft (TW). An oil baffle chamber (S) is formed at an inner surface of the second shaft (PW) and includes a first outflow (S1) and a second outflow (S2). A drive train for a motor vehicle may include such a drive train unit (HY, G).
