    摘要： A coolant supply system for an electric vehicle axle drive having an electric machine, in the electric machine housing of which a stator interacts with a rotor. The electric machine outputs to at least one vehicle wheel of the vehicle axle via a transmission arrangement. A coolant separator is arranged in the electric machine housing, which divides the interior of the electric machine housing into a radially outer stator chamber, in which the stator with its stator windings is arranged, and into a radially inner rotor chamber, which is separated therefrom in a largely fluid-tight manner and in which the rotor is arranged.

    摘要： 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.

    摘要： An electric machine, in particular an axial flux machine, including a rotor mounted in a dry chamber rotatable relative to a stator, the rotor having a rotor shaft with at least one first disk-shaped rotor member which is non-slidably arranged on the rotor shaft for conjoint rotation therewith, the stator having a first annular disk-shaped stator member and a second annular disk-shaped stator member which are arranged coaxially to one another and coaxially to the rotor shaft and are axially spaced apart from one another, the rotor being arranged in the space therebetween. The first stator member has a first stator winding, and the second stator member has a second stator winding, the first stator winding being arranged within a first hydraulic chamber, and the second stator winding being arranged within a second hydraulic chamber, at least part of the stator windings being able to come into contact with a hydraulic fluid in the hydraulic chambers The first stator winding has first winding ends which protrude from the first stator member and which extend in the axial direction radially above the stator member, and the second stator winding has second winding ends which protrude from the second stator member and which extend in the axial direction radially above the first stator member and the second stator member.

    摘要： Provided is a vehicle drive motor capable of maintaining lubrication of a bearing even in a case where an electric vehicle is not operated for a long period of time. The vehicle drive motor includes a casing in which a cylindrical stator coil is fixed to an inner peripheral surface and an oil passage is provided in an upper portion, an output shaft arranged in the casing and having a rotor fixed to a position facing the stator coil, a bearing that supports the output shaft, and an oil retaining portion that is arranged to face the bearing and stores oil supplied from the oil passage. The oil retaining portion is a pocket-shaped receptacle in which an upper side is lower than a lower end of the output shaft and a lower side is along a lower outer periphery of the bearing as viewed from an axial direction of the output shaft in front view.

    摘要： An improved efficiency cooling plate apparatus for full-scale clean fuel electric-powered aircraft having a cooling body including a plurality of bores, apertures and interior chambers working together to process and circulate fluid coolant and function as a heat sink device, interconnecting with the cooling system of an electric motor and cooperatively functioning to transfer thermal energy away from the electric motor using conduction, convection and radiation, while transporting heated fluid coolant away from heated motor components and to other components of a vehicle for further processing, then returning cooled fluid coolant into the cooling system of an electric motor, effectively partitioning heated fluid coolant, cooled fluid coolant, and electrical circuitry in a space saving design formed from a single part or minimal number of parts to reduce modes of failure and reduce required fasteners or connections to improve robustness and reliability while maintaining suitable aerodynamic characteristics.
