Embodiment Construction

[0054] Figure 1A A cross-sectional view of a drive assembly 1 for use in the present invention is shown. The drive assembly comprises a stator 30 having a hollow stator body 31 with an outer surface 32 around which a rotor 60 is arranged. The drive assembly also comprises a connector member 33 arranged at the vehicle side 2 of the assembly 1 for attaching the drive assembly to the vehicle. The connector member 33 comprises a shaft 34 having a diameter D1 and a flange 35 fixedly connected to the stator body 31 . Open end 7 of hollow stator body 31 has a larger inner diameter D2 than D1 to allow insertion of control electronics 42 through open end 7 when roadside cover plate 80 and roadside bearing 53 are separated from rotor 60 . Flange 35 is located within rotor 60 and has a larger diameter than portion 36 of shaft 34 that is external to peripheral surface 63 of rotor 60 . To support the rotational movement of the rotor 60 about the axis of rotation R, a bearing 52 is provide...

Abstract

An in-wheel motor for a vehicle is disclosed, comprising: a stator with a connector member for attaching the stator to the vehicle, the connector member comprising a shaft, an end plate of a larger diameter than the shaft, and a passage for coolant through said end plate, the stator further comprising a hollow stator body having a cylindrical outer surface and mounted to the connector member, wherein a plurality of cooling channels adapted for circulation of a liquid coolant extends along the hollow stator body and are in fluid connection with said coolant supply duct, said plurality of cooling channels having an inlet for supply of liquid coolant to the plurality of channels and an outlet for discharging liquid coolant from the plurality of channels; wherein, at a side opposite from the connector member, the hollow stator body has an open end with a diameter larger than the diameter of the shaft. The invention further relates to a cooling jacket for such an in-wheel motor.

Description

technical field [0001] The present invention relates to an in-wheel motor comprising a stator provided with electromagnets and a plurality of cooling passages extending along the stator body and through which coolant can flow to cool the electromagnets. The invention also relates to a cooling jacket for an in-wheel motor. Background technique [0002] US 2013 / 0126143 A1 describes a cooling jacket for cooling an electric motor, wherein the cooling jacket has one or more continuous S-shaped ducts covering the electric motor to conduct the working fluid, wherein each Each continuous S-shaped duct has at least: a forward portion and a rearward portion respectively extending along two mutually parallel but opposite circumferential directions; and a turning portion connected between the forward portion and the rearward portion. When a cooling jacket is used to cool an electric motor, the temperature of the working fluid within the S-shaped duct generally increases from one end of...
