Differential Gearing for a Vehicle and Drive Unit with an Electrical Machine and a Differential Gearing

A differential transmission (1) for a vehicle (100), comprising:

• a drive shaft (2) which is configured to be operatively drivingly connected to an electric machine (3);
• a first output shaft (4.1) and a second output shaft (4.2), each of the first output shaft (4.1) and the second output shaft (4.2) being configured to be operatively drivingly connected to a wheel (R1, R2) of the vehicle (100);
• a first planetary gear set (5), the first planetary gear set (5) having a first sun shaft (5.1), a first ring gear shaft (5.2), and a first carrier shaft (5.3), exactly one of the first sun shaft (5.1), the first ring gear shaft (5.2), or the first carrier shaft (5.3) of the first planetary gear set (5) being rotationally fixedly connected to exactly one of the first output shaft (4.1) or the second output shaft (4.2);
• a second planetary gear set (8), the second planetary gear set (8) having a second sun shaft (8.1), a second ring gear shaft (8.2), and a second carrier shaft (8.3), exactly one of the second sun shaft (8.1), the second ring gear shaft (8.2), or the second carrier shaft (8.3) of the second planetary gear set (8) being rotationally fixedly connected to exactly one of the first output shaft (4.1) or the second output shaft (4.2);
• an oil catchment device (6) rotationally fixedly connected to the first carrier shaft (5.3);
• and
• an oil feeding device (7) arranged on a stationary component and defining at least one channel (9) for feeding lubricant to the oil catchment device (6) via non-rotating components.
