Description

  The present invention relates to an auxiliary wheel-equipped wheel.

  In a kickboard, a tricycle, and a two-wheeled vehicle structure that are generally used by children today, wheels B are installed on a vehicle body A, and the vehicle body A moves forward by the rotation of the wheels B, as shown in FIG. However, since the wheel B is small, there is a possibility that danger may occur if the vehicle body A is overturned when the vehicle is curved, and the child body is poorly operated.

  This wheel defect also occurs in the egg-shaped wheel C structure. As shown in FIG. 9, an egg-shaped wheel C is installed on the vehicle body A in order to improve the stability at the time of the curve. When the egg-shaped wheel C is placed on the ground, the egg-shaped wheel C comes into contact with the central surface C1 at the center position of the egg-shaped wheel C. When the vehicle body A of the egg-shaped wheel C is curved, the vehicle body A is tilted by centrifugal force, and the egg-shaped wheel C is also tilted along the vehicle body A. As shown in FIG. 10, the wheel arc surfaces C2 on both sides of the egg-shaped wheel C are in contact with the ground to provide stability, so that the vehicle body A does not fall down. However, if the inclination angle between the egg-shaped wheel C and the ground is increased, it will also capsize.

  Therefore, in order to prevent the above-described danger, auxiliary wheels D1 are installed on both sides of the normal wheel D, respectively. As shown in FIG. 11, even if the wheel D is inclined, the vehicle body A is not tilted by the support of the auxiliary wheel D1, so that safety is improved. However, when the auxiliary wheel D1 is manufactured, the manufacturing cost and the cost and time for assembly are also increased. Furthermore, it is not practical because it easily generates noise during driving and also easily breaks down.

  The problem to be solved by the present invention is that when the vehicle is driven with an egg-shaped wheel, if the tilt angle is increased, it falls down. Therefore, if an auxiliary wheel is installed, safety is improved, but manufacturing and assembly costs are increased. is there.

  Accordingly, an object of the present invention is to provide a wheel with an auxiliary wheel body that has improved safety without increasing costs.

  In order to achieve the above-described object, the auxiliary wheel body-installed wheel of the present invention has extended wheel bodies on both sides of the main wheel body. Auxiliary wheel bodies are formed on the outside of the extended wheel body, and the outer diameter of the main wheel body of the wheel is larger than the outer diameter of the auxiliary wheel body, so when the wheel curves, the contact area of the ground increases, and the auxiliary wheel body overturns the car body. The most important feature is to prevent.

  The auxiliary wheel installation wheel of the present invention has a coaxial ring installed on both sides of the main wheel body, and the function as the auxiliary wheel is provided. This increases the contact area of the vehicle body and has the advantage of preventing overturning of the vehicle body.

  Further, since there is no need to install a known auxiliary wheel for supporting, there is an advantage that manufacturing cost and assembly cost can be saved, and the time required for them can be reduced, and noise and failure of tank construction can be prevented.

  In addition, the main wheel body and auxiliary wheel body of the present invention are manufactured by one-piece gas injection molding, injection molding, injection molding of outer tires, casting molding, or manufacturing by tire installation. Has the advantage of being simple.
