An electric drive for a vehicle comprises: an electric machine, a stator connected to a housing and comprising stator end-windings, a rotor rotatable relative to the stator, and a driveshaft connected to the rotor; a transmission to transmit a rotary movement from the driveshaft to a driveline; a sump containing fluid to cool and/or lubricate the electric machine and the transmission; a hydraulic arrangement comprising at least one bi-directional pump, a first suction line hydraulically connected with the pump, a stator path for cooling the stator, a second suction line connected with the pump, and a transmission path for cooling the transmission; a valve arrangement with multiple valves configured such that fluid is either supplied from the sump through the first suction line to the stator path, or through the second suction line to the transmission path.

Electric drive for a vehicle

An electric motor comprises: a motor housing, a stator connected to the motor housing, wherein the stator comprises first stator end-windings and second stator end-windings, a rotor rotatable relative to the stator, a driveshaft connected to the rotor in a rotationally fixed manner, wherein the driveshaft is rotatably supported in the motor housing about an axis of rotation, wherein an axial cooling arrangement is arranged axially adjacent and radially overlapping one of the first and second stator end-windings, wherein the axial cooling arrangement comprises a fluid chamber with a plurality of nozzles distributed in circumferential direction and directed towards said one of the first and second stator end-windings.

Electric motor cooling arrangement

An electric drive arrangement for a vehicle includes a housing, an electric machine, a transmission, and a hydraulic circuit for circulating a fluid to cool and lubricate the electric machine and the transmission.

Electric drive arrangement for a vehicle

An electric drive arrangement for a vehicle includes a housing. The electric drive arrangement includes an electric machine with a stator connected to the housing and a rotor with a rotor shaft rotatably supported in the housing. The electric drive arrangement includes a transmission to transmit a rotary movement from the rotor shaft to drive a driveline of the vehicle. The electric drive arrangement includes a hydraulic circuit for circulating a fluid to cool and lubricate the electric machine and the transmission.
