Description

  The present invention relates to a center cap for mounting a vehicle wheel.

  BACKGROUND ART Conventionally, a center cap of an automobile wheel (hereinafter sometimes simply referred to as a "wheel") is attached for the purpose of decoration or the purpose of preventing dirt or moisture from entering the center hole of the wheel. (See Patent Document 1).

  On the other hand, a hub ring may be used for the purpose of positioning (centering) the hub and the wheel when the wheel is mounted on the hub of the vehicle (see Patent Document 2).

Japanese Utility Model Publication No. 5-82602 Utility Model Registration No. 3175052

  However, as described in Patent Document 1, the center cap has a structure in which the center cap is attached by being fitted from the front surface side of the wheel, and thus the center cap may be unintentionally detached.

  In addition, considering the risk of accidental detachment, the center cap is made of lightweight resin, so there is a limit to the appearance of a luxurious appearance (no matter how much plating is applied). It was

  Therefore, the present invention has been made to solve such problems, and provides a center cap structure that does not structurally come off during wearing and has excellent appearance performance of a luxurious appearance. Is the task.

  In order to solve the above problems, the present invention is formed into a substantially cylindrical shape or a substantially cylindrical shape with a bottom, and is fitted into an inner peripheral portion that fits into a central protrusion of a vehicle-side hub and a central hole of an automobile wheel. A hook portion that has an outer peripheral portion and that extends toward the outside of the diameter of the center hole is formed on one end side that faces the vehicle side when mounted, and the other end side is at the same position as the outlet of the center hole or It is characterized in that it extends to the front side.

  By adopting such a configuration, it is possible to provide a center cap structure that does not come off structurally and has excellent appearance performance with a high-class appearance.

  In particular, in the case of wheels sold and distributed as after-parts, the inventor intentionally formed the center hole of the wheel into a large size in order to adapt it to various vehicles, and then installed a hub ring so as to fill the gap. By focusing on the fact that there is such a situation, by extending this hub ring to the front side of the wheel, we came up with the idea of also exerting the function as a center cap.

  In particular, the hub ring is made of metal (for example, aluminum) from the viewpoint of positioning a heavy wheel, but by using this material as it is, the designability as a center cap (using metal) It is also possible to improve the sense of luxury and precision.

  In addition, since it has a hooking portion that expands to the outside of the diameter of the wheel center hole, it is possible to structurally prevent the center cap from falling off while mounted on the vehicle. .

  Further, if a pressing force of a certain amount or more is applied to the outer peripheral portion, the lock mechanism can be set to the same position as the outer peripheral portion surface, and is provided with a lock mechanism composed of a sphere that is constantly urged outward in the radial direction. Good.

  According to this structure, it is possible to prevent the hub ring integrated type center cap from being unintentionally detached from the wheel and dropping when the wheel is attached or detached.

  Moreover, you may form the recessed part which can mount a genuine part on the other end side.

  With this configuration, parts that are genuinely mounted on the wheel (specifically, plate-shaped parts that are mounted as a center cap and that display the vehicle manufacturer's logo, etc.) can be attached. It is possible to improve the satisfaction of the owner.

  By applying the present invention, it is possible to provide a center cap structure that does not structurally come off and is further excellent in the performance performance of a high-class appearance.

It is a sectional view of a hub ring integrated type center cap which is an example of an embodiment of the present invention. It is sectional drawing which showed the state before and after mounting the hub ring integrated center cap which is an example of embodiment of this invention to a wheel. FIG. 3 is an enlarged view of part α of FIG. 2. FIG. 3 is an assembly view of a vehicle-side hub, a hub ring-integrated center cap, and a wheel. It is sectional drawing which showed the 2nd Example of the hub ring integrated type center cap.

  Hereinafter, a hub ring integrated type center cap 100, which is an example of an embodiment of the present invention, will be described with reference to the accompanying drawings. It should be noted that in order to facilitate understanding of the drawings, there are some portions in which the sizes and dimensions of the respective portions are exaggerated and expressed, and some portions do not necessarily match the actual product. In addition, each drawing is to be viewed in the direction of the reference numeral, and is basically expressed as up / down / left / right, front, back.

<Structure of hub ring integrated center cap>
The hub ring integrated type center cap 100 shown as an example of the embodiment of the present invention is formed into a substantially bottomed cylinder, and has a general shape like a substantially U shape when the cross section is seen. The material is made of aluminum alloy.

  The hub ring integrated type center cap 100 includes an inner peripheral portion 104 that fits into the center protrusion 14 (see FIG. 4) of the vehicle-side hub and an outer peripheral portion 101 that fits into the center hole 34 of the automobile wheel. On one end side facing the vehicle side, a hooking portion 102 is formed that extends further outside than the diameter of the center hole 34 of the wheel. Further, the top portion 103, which is the other end side, extends to the surface side beyond the position β of the outlet of the central hole 34.

  Reference numeral 110 denotes a lock mechanism that is capable of sinking to the same position as the surface of the outer peripheral portion 101 when a pressing force of a certain amount or more is applied, and that is a spherical body that is constantly biased outward in the radial direction. .

<Operation and function of hub ring integrated center cap>
The hub ring integrated center cap 100 is very easy to use. As shown in FIG. 2, the wheel 30 is attached by being pushed from the inside of the wheel 30 toward the center hole 34 so as to be inserted from the top portion 103 side. Since the lock mechanism 110 exists, it is fixed in that position when pushed. However, it is possible to remove it by overcoming this locking mechanism by applying a certain amount of force.

  With the hub ring integrated type center cap 100 attached to the wheel 30, as shown in FIG. 4, it is attached together with the wheel 30 to the hub 12 of the vehicle.

  The inner diameter d1 of the center hole 30 of the wheel and the outer diameter D2 of the outer peripheral portion 101 of the hub ring integrated type center cap 100 are adjusted to a size that can be fitted without looseness, and the inner circumference of the hub ring integrated type center cap 100 is adjusted. Since the inner diameter d2 of the portion 104 and the outer diameter D1 of the central projection 14 of the hub 12 are also adjusted to a size that can be fitted without rattling, when the wheel 30 is attached to the hub 12 via the hub ring integrated center cap 100. The positioning (centering) of the hub 12 and the wheel 30 is automatically completed.

  Then, the fastening bolt 36 is screwed into the bolt hole 13 formed in the hub 12 (via the bolt insertion hole 32 formed in the wheel 30) to fix the wheel 30.

  On one end side of the hub ring integrated type center cap 100 facing the vehicle side (hub 12 side) at the time of mounting, a hook portion 102 (outer diameter of the hook portion 102) that extends outside the inner diameter d1 of the center hole 34 of the wheel 30. Since D3> the inner diameter d1) of the center hole 34 is formed, the hub ring-integrated center cap 100 is structurally never detached from the wheel 30 when mounted on a vehicle.

  Furthermore, since the other end side (top portion 103) of the hub ring integrated center cap 100 extends to the surface side of the outlet surface β of the center hole 34, this portion can be easily visually visualized from the outside. You can check. That is, the top portion 103 is made of the same metal as the hub ring (for example, aluminum), but by using this material as it is, the designability as a center cap (a high-class feeling and a precision feeling due to the use of metal) can be obtained. ) Has improved dramatically.

<Other configuration examples>
Although the top portion 103 of the hub ring integrated center cap 100 is closed (cylindrical shape with bottom) in the above description, it may be opened (cylindrical shape) as shown in FIG. At this time, a configuration may be adopted in which the concave portion 205 on which genuine parts can be mounted is formed.

  According to this structure, the component 70 that is genuinely attached to the wheel (specifically, the plate-shaped component that is attached as the center cap and has the logo of the vehicle manufacturer and the like displayed) can be attached. It is possible to improve the satisfaction of the vehicle owner.
