Transmission for a motor vehicle

1. A transmission (G) for a motor vehicle (K), comprising:

a housing (GG);

a hydraulic unit (HY);

an input shaft (GW 1 ) and an output shaft (GW 2 ); and

a gear set (RS) enclosed by the housing (GG), the gear set (RS) configured for making different transmission ratios available between the input shaft (GW 1 ) and the output shaft (GW 2 ),

wherein oil for lubrication collects in an oil sump (S) of the transmission (G) due to gravity, and the oil is feedable to the gear set (RS),

wherein an oil drainage channel (D) is formed by the housing (GG) and/or by an element (HY) connected to the housing (GG), the oil drainage channel (D) is arranged underneath the gear set (RS), and the oil drainage channel (D) comprises

at least one gear set-side inlet port (DE 1 , DE 2 , DE 3 ),

a fully closed underside (DL), and

a single oil sump-side outlet port (DA) at one end of the oil drainage channel (D),

wherein the at least inlet port (DE 1 , DE 2 , DE 3 ), the fully closed underside (DL), and the single oil sump-side outlet port (DA) are configured and arranged such that oil from the gear set (RS) enters the oil drainage channel (D) through the at least one inlet port (DE 1 , DE 2 , DE 3 ) and is guided along the fully closed underside (DL) to the outlet port (DA), and

wherein a suction port (OF) of the hydraulic unit (HY) is arranged in the oil sump (S) underneath the fully closed underside (DL) of the oil drainage channel (D) and axially offset with respect to the outlet port (DA).

2. The transmission (G) of claim 1 , wherein the at least one inlet port (DE 1 , DE 2 , DE 3 ) is arranged axially offset with respect to the outlet port (DA).

3. The transmission (G) of claim 1 , wherein the at least one inlet port (DE 1 , DE 2 , DE 3 ) is a plurality of inlet ports (DE 1 , DE 2 , DE 3 ).

4. The transmission (G) of claim 1 , wherein the outlet port (DA) is the only outlet port for the oil drainage channel (D).

5. The transmission (G) of claim 1 , wherein the closed underside of the oil drainage channel (DL) is at least partially formed by the hydraulic unit (HY), and the hydraulic unit (HY) is connected to the housing (GG).

6. The transmission (G) of claim 1 , wherein the housing (GG) comprises a housing wall (ZP), and the outlet port (DA) is arranged directly under the housing wall (ZP).

7. The transmission (G) of claim 6 , wherein the housing wall (ZP) is arranged between the gear set (RS) and a cavity (G 1 ) of the transmission (G) positioned upstream from the gear set (RS), and the cavity (G 1 ) is at least partially enclosed by the housing (GG).

8. The transmission (G) of claim 7 , further comprising an electric machine (EM) and/or a torque converter (TC) disposed within the cavity (G 1 ).

9. The transmission (G) of claim 7 , wherein the cavity (G 1 ) is configured as a wet space, and oil flowing out of the cavity (G 1 ) collects in the oil sump (S) due to gravity.

10. The transmission (G) of claim 7 , wherein an opening (ZPA) is provided in the housing wall (ZP) for pressure compensation between the gear set (RS) and the cavity (G 1 ).

11. The transmission (G) of claim 1 , wherein the transmission (G) is configured for a motor vehicle (K) that comprises a drive train aligned in parallel to a direction of travel (X) of the motor vehicle (K), and the input shaft (GW 1 ) and the output shaft (GW 2 ) are aligned in parallel to the direction of travel (X).

12. A motor vehicle (K) comprising the transmission (G) of claim 1 .

13. The transmission (G) of claim 1 , wherein an opposite end of the oil drainage channel (D) is spaced from the one end of oil drainage channel (D) with the single oil sump-side outlet port (DA), and the opposite end of the oil drainage channel (D) is closed.
