Each motor comprises a brake drum (35) connected to a rotor (24), extending coaxially within the housing (10,10') near an inner surface a circumferential wall (8) of the housing. A brake shoe assembly (51,52,55,56) is movable in a radial direction R against the brake drum (35), and an actuator (18,18') is placed on an outer surface (17,17') of the circumferential wall (8,8') of the housing (10,10'), connected to the brake shoe assembly (51,52,55,56). The assembly provides a low-floor portal frame member, with two in-wheel motors and a brake system that has relatively small axial dimensions and provides a reduced space envelope at the vehicle side.
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.
An in-wheel electric motor includes at a vehicle side an elongated connector, a cylindrical stator body connected to the connector and on an outer surface of the stator body equipped with stator windings, a cylindrical rotor body enclosing the stator, and a power electronics device for powering the stator windings. The connector is provided with a first opening of a feed channel for coolant and a second opening of a return channel for coolant, each of the feed and return channels being parallel to an axial direction of the connector. The electric motor includes a cooling circuitry with a feed connector and a return connector for coolant, which circuitry includes a coolant supply channel that extends from the feed connector through first the power electronics device and subsequently through a cooling jacket that is situated at the perimeter of the cylindrical stator body and from there to the return connector.
The invention relates to a drive assembly for an in-wheel motor, which in-wheel motor has a rotor, said rotor having an axis of rotation, a peripheral outer surface and a transverse road side surface, wherein the drive assembly is provided with an assembly (200) adapted for supporting two tyres and comprising a circumferential first part (210) and a circumferential second part (250), each part provided with a rim-section for carrying a respective one of said two tyres, wherein the first part and second part are adapted to be mounted on the rotor from and at the transverse road side surface of the rotor and are detachable from the rotor from said transverse road side surface, and wherein the second part is detachable from the rotor independently from said first part,
