1. A housing (1) for a drive system comprising:
a first housing portion (2) for receiving a stator of the drive system; and
a second housing portion (3) for receiving a transmission arrangement (G);
wherein a first coolant channel (4) for cooling the stator is formed in or on the first housing portion (2), and wherein a second coolant channel (5) for cooling the transmission arrangement (G) is formed in or on the second housing portion (3), and wherein the first coolant channel (4) is fluidically connected to the second coolant channel (5) such that a coolant can be conducted through the first coolant channel (4) into the second coolant channel (5), wherein the first housing portion (2) also has a third coolant channel (6) which is fluidically connected to the second coolant channel (5), wherein the first coolant channel (4) has a coolant inlet for an inlet of the coolant, and wherein the third coolant channel (6) has a coolant outlet (6a) for an outlet of the coolant.
