A new type of ring-shaped shaftless wheel

Abstract

The utility model relates to the field of vehicle wheel design and manufacturing technology, the utility model discloses a novel ring type shaftless wheel, including inner ring stator, the inner ring stator is annular columnar structure, is used for fixedly connected in the vehicle body, and the outer wall is provided with excitation coil along the circumference, outer ring rotor, the annular structure of the outer ring rotor is set up in the outer side of inner ring stator, and the inner wall is provided with permanent magnet along the circumference, permanent magnet and excitation coil concentric opposite and gap cooperation, form electromagnetic drive pair, tire main part, be located in the outer wall of outer ring rotor, this novel ring type shaftless wheel adopts the shaftless design of inner ring stator fixed, outer ring rotor rotation, is different from the traditional motor vehicle wheel and needs through the axle support, external power drive and rotation, cancels center axle and wheel hub completely, makes the hollow region of wheel center form through, adapts to the scene that needs large diameter wheel and needs to utilize the central space, solved the structural limitation of traditional shafted wheel center space unable to utilize.
