    摘要： An electric vehicle drive assembly includes an electric motor mounted to engage with a wheel of a vehicle. The electric motor includes a rotor and a magnetic assembly. The rotor is rotatably mounted in a stator through interposition of an internal rolling bearing, which is positioned near the wheel, and an external rolling bearing, which is positioned at some distance from the wheel. The magnetic assembly is designed to rotationally drive the rotor. The rotor is provided with a heat pipe having at least one condensation zone, for condensing a heat-transfer liquid, and at least one evaporation zone, for evaporating the heat-transfer liquid. The evaporation zone is arranged to extend axially inside the internal rolling bearing.

    摘要： A method for producing a heat pipe comprises the following steps, performed on a first tube made from a malleable material: the diameter of the tube is swaged at a first end, and the end thus swaged is sealed closed; a second tube, of a smaller diameter than the first, is inserted into the second end of the first tube the second end of the first tube is swaged around the second tube and the interface between the two tubes is sealed the pipe thus created is partially filled with a heat-transfer fluid the air contained in the pipe is removed; and the free end of the second tube is sealed closed.
