Frame with a brake assembly for an electric vehicle

Assembly of a frame member for an electric vehicle comprising a transverse member with at each end a housing connected to the transverse member and two in-wheel motors connected to a respective housing, each housing having a side wall and an axially oriented circumferential wall, wherein the assembly comprises for each in wheel motor:

• a non-rotating axle part connected to the side wall of a respective housing, the circumferential wall enclosing a toroidal chamber around the axle part,
• a bearing on the axle part supporting a rotor of the in-wheel motor,
• a brake drum connected to the rotor, extending coaxially within the housing near an inner surface the circumferential wall,
• a brake shoe assembly connected to the axle part to be movable in a radial direction R against the brake drum, and
• an actuator placed on an outer surface of the circumferential wall of the housing, connected to the brake shoe assembly.

Electric vehicle, in particular a bus for the transport of people, comprising a frame member with:

• a transverse member with at each end a housing connected to the transverse member and two in-wheel motors connected to a respective housing, each housing having a side wall and an axially oriented circumferential wall, wherein the assembly comprises for each in wheel motor:
• a non-rotating axle part connected to the side wall of a respective housing, the circumferential wall enclosing a toroidal space around the axle part,
• a bearing on the axle part supporting a rotor of the in-wheel motor, a brake drum connected to the rotor, extending coaxially within the housing near an inner surface the circumferential wall,
• a brake shoe assembly connected to the axle part to be movable in a radial direction R against the brake drum, and
• an actuator placed on an outer surface of the circumferential wall of the housing, connected to the brake shoe assembly, and a bottom support of a passenger space extending between the side walls.
