Abstract

A wheel driven mechanism adapted for driving a vehicle without motor is disclosed to include a rotor defining therein an accommodation chamber, a plurality of permanent magnets arranged in the accommodation chamber of the rotor, a stator having one or a number of stator segments, and one or a number of electromagnets located on the stator segment(s) within the accommodation chamber and facing toward the permanent magnets at the stator to enhance the convenience of use of the wheel driven mechanism.

Claims

a rotor defining therein an accommodation chamber;

a plurality of permanent magnets mounted inside said accommodation chamber of said rotor;

a stator comprising at least one stator segment; and

at least one electromagnet set arranged at said stator segment and disposed inside said accommodation chamber of said rotor and facing toward said permanent magnets.

2. The wheel driven mechanism as recited in claim 1, further comprising a gap defined between said permanent magnets at said rotor and said electromagnet set at said stator segment.

3. The wheel driven mechanism as recited in claim 2, further comprising at least one bearing set between said rotor and said at least one stator segment.

4. The wheel driven mechanism as recited in claim 1, wherein said stator comprises a bracket, and said stator segment is located on said bracket.

5. The wheel driven mechanism as recited in claim 2, wherein said stator comprises a bracket, and said stator segment is located on said bracket.

6. The wheel driven mechanism as recited in claim 3, wherein said stator comprises a bracket, and said stator segment is located on said bracket.

7. The wheel driven mechanism as recited in claim 4, further comprising at least one adjustment unit set between said bracket and said stator segment and controllable to adjust the relative positioning between said electromagnet set at said stator segment and said permanent magnets at said rotor.

8. The wheel driven mechanism as recited in claim 5, further comprising at least one adjustment unit set between said bracket and said stator segment and controllable to adjust the relative positioning between said electromagnet set at said stator segment and said permanent magnets at said rotor.

9. The wheel driven mechanism as recited in claim 6, further comprising at least one adjustment unit set between said bracket and said stator segment and controllable to adjust the relative positioning between said electromagnet set at said stator segment and said permanent magnets at said rotor.

10. The wheel driven mechanism as recited in claim 1, further comprising at least one waterproof gasket set between said rotor and said stator to watertightly seal said accommodation chamber into an enclosed space.

11. The wheel driven mechanism as recited in claim 2, further comprising at least one waterproof gasket set between said rotor and said stator to watertightly seal said accommodation chamber into an enclosed space.

12. The wheel driven mechanism as recited in claim 3, further comprising at least one waterproof gasket set between said rotor and said stator to watertightly seal said accommodation chamber into an enclosed space.

13. The wheel driven mechanism as recited in claim 10, further comprising a drainage passage set between said rotor and said stator.
