Abstract
In an electrical machine for the hybrid drive of a vehicle, an annular cooling jacket extends between a housing and a casing. The cooling jacket is connected to a coolant inlet and a coolant outlet so that coolant is axially introduced into the cooling jacket. The coolant inlet and the coolant outlet are situated next to each other in the circumferential direction of the housing and are hydraulically connected to a deflection section by way of coolant ducts. Coolant introduced into the cooling jacket flows in two partial flows in opposite directions, to the deflection section through coolant ducts forming an intake. The coolant is deflected back to the coolant outlet through a coolant duct forming a return. The coolant flows through the coolant duct of the return and the axially adjacent coolant duct of the intake in opposite directions.

11. An electrical machine for a hybrid vehicle, comprising:
-
a housing; a casing that concentrically surrounds the housing; an annular cooling jacket that is sealed in a fluid-tight manner and allows a coolant to pass through, extending between the housing and the casing; at least one coolant inlet and at least one coolant outlet situated adjacently in the circumferential direction of the housing; a deflection section situated diametrically opposite the at least one coolant inlet; wherein the cooling jacket is connected to at least one coolant inlet and to at least one coolant outlet so that coolant is axially introduced into the cooling jacket and discharged therefrom; wherein the at least one coolant inlet and the at least one coolant outlet are hydraulically connected to the deflection section by coolant ducts extending in the circumferential direction; wherein coolant introduced into the cooling jacket flows to the deflection section in two partial streams having opposite flow directions, through coolant ducts forming a supply; and wherein coolant is deflected so that the coolant flows back to the coolant outlet in an opposite direction of the supply through at least one coolant duct forming a return, the at least one coolant duct of the return axially adjacent to a coolant duct of the supply. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
