    • نبذة مختصرة :
      A shaft receiving section of a simulation wheel is attached to a hub of a vehicle such that the shaft receiving section is located outside the vehicle. A tire mounting section surrounding the shaft receiving section concentrically with the shaft receiving section with a bearing being interposed between the shaft receiving section and the tire mounting section and further surrounding the peripheral surface of the hub to allow a tire to be mounted at a portion surrounding the peripheral surface of the hub is provided. The tire is mounted on the tire mounting section. The shaft receiving section is made rotatable with the rotation of the tire mounting section being stopped. Load is applied to an axle from a dynamometer.

    • Claim:
      1. A simulation wheel comprising: a shaft receiving section having a hub attachment structure attached to a hub of a wheel of a vehicle instead of a wheel with a tire, and a joint attachment structure on an outer surface side to which a joint is attached; and a tire mounting section surrounding the shaft receiving section concentrically with the shaft receiving section with a bearing being interposed between the shaft receiving section and the tire mounting section, and further surrounding a peripheral surface of the hub to allow a tire to be mounted at a portion surrounding the peripheral surface of the hub; the shaft receiving section being rotatable with rotation of the tire mounting section being stopped.
    • Claim:
      2. The simulation wheel according to claim 1, further comprising a key coupling mechanism for coupling the shaft receiving section and the tire mounting section by using a detachable key to restrict relative rotation between the shaft receiving section and the tire mounting section, thereby allowing the vehicle to run with the shaft receiving section and the tire mounting section being coupled by using the key.
    • Claim:
      3. A vehicle testing apparatus comprising: a simulation wheel comprising: a shaft receiving section having a hub attachment structure attached to a hub of a wheel of a vehicle instead of a wheel with a tire, and a joint attachment structure on an outer surface side to which a joint is attached, and a tire mounting section surrounding the shaft receiving section concentrically with the shaft receiving section with a bearing being interposed between the shaft receiving section and the tire mounting section, and further surrounding a peripheral surface of the hub to allow a tire to be mounted at a portion surrounding the peripheral surface of the hub, the shaft receiving section being rotatable with rotation of the tire mounting section being stopped; a constant velocity joint whose one end is attached to the shaft receiving section; and a dynamometer to which the other end of the constant velocity joint is attached to transmit torque to the shaft receiving section via the constant velocity joint.
