Electric drive unit that includes a fluid flow path

A drive unit for a vehicle, comprising:

• an electric motor that includes a rotor shaft that defines a hollow that is accessible via an opening defined at an axial end of the rotor shaft;
• an output shaft that extends into the hollow through the opening;
• and
• a housing that houses the electric motor and defines a fluid flow path that conveys fluid, the housing having a collar portion that extends circumferentially about the output shaft and a first holding portion disposed on a first axial side of the collar portion and having at least one baffle,
• wherein the fluid flow path is configured to convey the fluid, such that a first portion of the fluid flows onto the collar portion via a passage of the housing and through the opening into the hollow defined by the rotor shaft in a first axial direction, and a second portion of the fluid flows onto the collar portion via the passage of the housing and from the collar portion to the first holding portion in the first axial direction, and wherein the at least one baffle is configured to disrupt circumferential flow of the second portion of the fluid along the first holding portion of the housing.
