Abstract
A wheel assembly structure of a vehicle may include a wheel on which a tire of the vehicle is mounted, a rotor housing connected to the wheel and configured to rotate with the wheel, a stator housing configured to be fixed to a vehicle body, and configured to rotate the rotor housing based on an application of an electrical current at the stator housing, and a damping device coupled between an inner circumference of the wheel and an outer circumference of the rotor housing and configured to alleviate a shock transferred from the wheel to the rotor housing.
Claims20
A vehicle wheel assembly structure, comprising:
- a tire;
- a wheel on which the tire is mounted;
- a rotor housing connected to the wheel and configured to rotate with the wheel;
- a stator housing configured to be fixed to a vehicle body, and configured to rotate the rotor housing based on an application of an electrical current at the stator housing;
- and
- a damping device coupled between an inner circumference of the wheel and an outer circumference of the rotor housing, wherein the damping device is configured to alleviate a first shock transferred from the wheel to the rotor housing.
A vehicle wheel assembly structure comprising:
- a wheel hub;
- a wheel fixed to the wheel hub;
- a wheel hub bearing;
- a suspension arm rotatably coupled to the wheel hub via the wheel hub bearing, wherein the suspension arm is configured to be rotatably coupled to a vehicle body such that the suspension arm extends between the vehicle body and the wheel hub;
- a suspension system comprising:
- a shock absorber, and
- a spring, wherein the suspension system is configured to be disposed between the vehicle body and the suspension arm;
- an in-wheel electric motor comprising:
- a motor bearing,
- a rotor housing, and
- a stator housing rotatably coupled to the rotor housing via the motor bearing, wherein the in-wheel electric motor is disposed radially outside of the wheel hub and at least partially in the wheel;
- a damping device fixed to the wheel radially outside of the in-wheel electric motor and fixed to the rotor housing of the in-wheel electric motor, wherein the damping device is configured such that the in-wheel electric motor can drive rotation of the wheel via the damping device;
- and
- a motor bracket fixed to the stator housing of the in-wheel electric motor and configured to be fixed to the vehicle body such that the stator housing of the in-wheel electric motor is fixed relative to the vehicle body.
A vehicle comprising:
- a body;
- a wheel hub;
- a wheel fixed to the wheel hub;
- a wheel hub bearing;
- a suspension arm rotatably coupled to the wheel hub via the wheel hub bearing, wherein the suspension arm is rotatably coupled to the body, such that the suspension arm extends between the body and the wheel hub;
- a suspension system comprising:
- a shock absorber, and
- a spring, wherein the suspension system is disposed between the body and the suspension arm;
- an in-wheel electric motor comprising:
- a motor bearing,
- a rotor housing, and
- a stator housing rotatably coupled to the rotor housing via the motor bearing, wherein the in-wheel electric motor is disposed radially outside of the wheel hub and at least partially in the wheel;
- a damping device fixed to the wheel radially outside of the in-wheel electric motor and fixed to the rotor housing of the in-wheel electric motor, wherein the damping device is configured such that the in-wheel electric motor can drive rotation of the wheel via the damping device;
- and
- a motor bracket fixed to the stator housing of the in-wheel electric motor and fixed to the body, such that the stator housing of the in-wheel electric motor is fixed relative to the body.
