Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for attaching and detaching a wheel cover that can be attached to and detached from the side surface of a vehicle wheel.

[Conventional technology]

Conventionally, as a structure for attaching and detaching a wheel cover, there was a structure shown in FIGS. 3 and 4 disclosed in Japanese Patent Publication No. 54-13052 and the like. That is, in the figure, A
is a wheel, B is a rim to which a tire (not shown) is attached, and C is a disk. Reference numeral D designates a wheel cover that is attached to the side surface of the wheel A, and mounting legs E are provided on the back surface of the wheel cover at predetermined intervals on a concentric circle. F is an elastic ring-shaped wire ring, and the wire ring F has a plurality of arcuate portions G projecting outward at predetermined intervals. And line ring F
is attached to the mounting leg E of the wheel cover D by this arcuate portion G.

Therefore, when the back surface of the wheel cover D is pressed against the side surface of the wheel A, each arcuate portion G is elastically deformed inward by the inner peripheral surface of the rim B, and then restored by the annular recess H of the rim B. and then mate.
Thereby, the wheel cover D is fixed to the side surface of the wheel A.

Other conventional examples include JP-A-56-67620 and JP-A-56-67621 shown in FIGS. 5 and 6.
The invention of the publication is disclosed.

That is, in the figure, A is a wheel, B is a rim to which a tire (not shown) is attached, and C is a disk. Reference numeral D designates a plastic wheel cover that is attached to the side surface of the disk C, and tongue-like covers F are integrally protruded from the rear surface of the wheel cover at predetermined intervals via connecting portions E on a concentric circle. In addition, the connecting part E is given elastic force in the radial direction,
A circumferential inner groove G is formed inside the tongue-shaped cover F. H is a ring-shaped wire ring having elasticity, and the wire ring H is formed with a plurality of arcuate portions I projecting outward at predetermined intervals, and the wire ring H is a horizontal connection of the arcuate portions I. By bringing the side J into contact with the inner groove G of the tongue-shaped cover F, the tongue-shaped cover F receives a preload and is attached to the wheel cover D.

Therefore, when the back surface of the wheel cover D is pressed against the side surface of the wheel A, each arcuate portion I is elastically deformed inwardly by the inner peripheral surface of the rim B via the tongue-like cover F, and then Annular recess K of rim B
The wheel cover D is thereby fixed to the side surface of the wheel A.

[Problem that the invention attempts to solve]

However, in the former example shown in Japanese Patent Publication No. 54-13052, the arcuate portion G of the wire ring F is configured to be mounted by directly pressing against the annular recess H of the rim B. There is a problem that scratches and the like are likely to occur.

In the latter inventions disclosed in JP-A-56-67620 and JP-A-56-67621, rattling noise is avoided by the tongue-shaped cover F, and by the arcuate portion I of the wire ring H. Although it is possible to prevent the rim B from being scratched, the arcuate portion I of the wire ring H is inserted into the inner groove G of the tongue-like cover F.
Since the structure is such that a preload is applied by making contact with the tongue-shaped cover F, the force pushing outward by the wire ring H is applied to the tongue-shaped cover F.
There is a problem in that the holding force when attached to the wheel A is insufficient because the repulsive force is weakened by the repulsive force of the wheel A. On the other hand, the invention disclosed in Japanese Patent Publication No. 41-2323 solves the problem of insufficient holding force when the wheel cap is attached to the wheel, but There is a problem that the operation to make the ring grip the seat is troublesome.

[Means for solving problems]

The present invention was developed to solve the above-mentioned problems with the conventional technology. A retainer ring consisting of an annular recess and an annular vertical part connected to the annular recess is fixed to the flat plate part by bolting, and mounting legs are attached to the back surface of the wheel cover at intervals on a concentric circle. The mounting legs are arranged so that a ring-shaped elastic wire ring having a plurality of gate-shaped parts protruding outward at the same intervals as the mounting legs can be freely moved in the radial direction. A wheel cover device for a vehicle, characterized in that the end of the elastic wire ring is inserted into the mounting leg so that its tip protrudes from the outer surface of the mounting leg, and the tip of the portal portion of the elastic wire ring is fitted into the annular recess of the retainer ring. It is destructured.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the embodiment shown in FIGS. 1 and 2. Note that FIG. 1 is a longitudinal cross-sectional view showing the main parts of the vehicle wheel cover mounting/detaching structure according to the present invention, and FIG. 2 is a rear view of the components of the same mounting/detaching structure.

In the above drawings, reference numeral 1 indicates a wheel excluding tires, which is composed of a disk 2 and a rim 3 on which the tires are mounted. 4 is a wheel cover (wheel cap) attached to disk 2
Attachment legs 5 are integrally protruded from the back surface at intervals on a concentric circle.

Reference numeral 6 denotes a retainer ring fixed to the side surface of the disk 2, and the retainer ring 6 includes a ring-shaped flat plate part 7, an annular recessed part 8 erected to bulge outward from the outer periphery of the flat plate part 7, and a retainer ring 6. It consists of an annular vertical part 9 connected to an annular recess 8, and an insertion hole 11 for a bolt 10 is formed in the flat plate part 7. Then, after the retainer ring 6 contacts the flat plate part 7 concentrically with the side surface of the disk 2, the insertion hole of the flat plate part 7 is inserted into the female thread of the disk 2.
It is fixed by screwing a bolt 10 inserted into 1 and tightening it.

12 is a ring-shaped elastic ring having elasticity;
This elastic wire ring 12 is formed with a plurality of gate-shaped parts 13 that protrude outward at the same intervals as the mounting legs 5, and the gate-shaped parts 13 have parallel vertical sides extending in the radial direction. 14a, 14b, and a horizontal connecting side 15 connecting their tips.

Therefore, with respect to the mounting leg 5 of the wheel cover 4, the elastic wire ring 12 is attached to the vertical side 14a of the portal portion 13,
14b is inserted so as to be movable in the radial direction, and is attached so that the horizontal connecting side 15 protrudes from the outer surface of the mounting leg 5.

Next, to explain the operation of the above embodiment, first,
When the back surface of the wheel cover 4 is pressed against the side surface of the disk 2, the horizontal connecting sides 15 of each portal portion 13 come into contact with the inner peripheral surface of the annular vertical portion 9 of the retainer ring 6. is elastically deformed inward and then restored and fitted in the annular recess 8, whereby the wheel cover 4 is fixed to the side surface of the disk 2.

[Effect of idea]

As described above, the vehicle wheel cover attachment/removal structure of the present invention includes a ring-shaped flat plate portion, an annular recess bulging outward from the outer periphery of the ring-shaped flat plate portion, and an annular recess connected to the annular recess, as described above. A retainer ring consisting of an annular vertical part provided above is fixed by bolting to the flat plate part, and mounting legs protruding from the back surface of the wheel cover at intervals on a concentric circle and identical to the mounting legs are provided. A ring-shaped elastic wire ring having a plurality of gate-shaped parts protruding outward at intervals is inserted into the mounting leg so that the gate-shaped parts are movable in the radial direction, and the tip thereof is connected to the mounting leg. Since the wheel cover is attached so as to protrude from the outer surface of the wheel cover, and the tip of the portal portion of the elastic wire ring fits into the annular recess of the retainer ring, it is easy to attach the wheel cover, and the vehicle Due to the circumferential force generated by driving, the engagement of the wheel cover with the disk of the wheel becomes stronger, so that the wheel cover will not be accidentally separated from the wheel.

In addition, the wheel cover is attached to the wheel via the retainer ring and mounting legs fixed to the side of the disc, which prevents damage to the rim when attaching and detaching the wheel cover, and also prevents brake damage. Even if the temperature of the wheel rises due to the frictional heat generated during operation, very little of this wheel heat is transferred to the wheel cover, so the disadvantage of the wheel cover becoming distorted due to heat deformation will soon be resolved. There are various effects.
