Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for a wheel cover of an automobile.

[0002]

[Prior Art]

 In recent years, when attaching a wheel cover to an automobile wheel, it is roughly divided into a method of attaching the wheel cover to the hump part of the wheel rim by pressing the periphery of the wheel cover with an annular spring, and Alternatively, there is a method in which the wheel cover is attached by a plate-like locking spring, or by using the attachment hole of the hub mechanism provided around the hub hole, but the former is the spring pressure of the annular spring. There is a risk that the wheel cover will fall off during running due to the loosening of the wheel cover, and in the latter case, the wheel cover may fall off due to the loosening of the plate-shaped locking spring. If the wheel cover itself is deformed, the eccentric force will be applied to the wheels and the running will be adversely affected. It can not be avoided on. Accidents due to various types of wheel covers tend to increase as automobile driving shifts to particularly high speeds and rough roads.

[0003]

[Problems to be solved by the device]

 The purpose of this invention is to obtain a center lock type wheel cover that can be firmly fixed so as not to fall off even at high speeds or when traveling on rough roads.

[0004]

[Means for Solving the Problems]

 A center lock type wheel characterized in that a cylindrical member provided in connection with a wheel cover is fixed to an inner wall of a hub hole forming portion of a wheel disc, and a cylindrical portion provided in a fixing cap is fixed to the cylindrical member. The structure of the cover.

[0005]

[Operation] When attaching the wheel cover to the wheel disc, the wheel cover components are directly fixed to the inner wall of the hub hole at the center, and then fixed again with the fixing caps, so the wheel cover is firmly fixed. It is possible to prevent the risk of the wheel cover falling off even if the operation is shifted to high speed.

【Example】

 FIG. 1 is a front view of the wheel cover (1) of the present invention, showing a state in which the wheel cover (1) is attached to a hub hole forming portion (2) formed in a wheel disc with a cap (3), and (4) is a hub hole. , (H) shows a hole for designing, etc., and (R) shows a wheel rim. Figure 2 shows the cross section of the main part of the wheel cover (1) of the present invention. The cylindrical part (5) provided at the center of the wheel cover (1) is the hub hole forming part (2) of the wheel disc. It is designed to fit inside. That is, an undercut portion (4 ') is formed in the hub hole (4), and a concave ring portion (5') provided in the cylindrical portion (5) is fitted therein. As a result, the hub hole (4) and the wheel cover (1) are temporarily fixed, and then the fixing cap (3) is mounted in the cylindrical portion (5) to further strengthen the fixing. The fixing cap (3) is provided with a screw portion (a ') for screwing with the screw portion (a) provided on the outer side of the cylindrical portion (5) on the outer side of the cylindrical body portion (6). By screwing in the fixing cap (3) from above, the screw parts (a) and (a ') are screwed together, and the screwing of the fixing cap (3) is advanced so that the cylinder The part (5) is expanded outwardly in the directions of arrows (a) and (a '), so that the wheel cover (1) is more strongly attached to the hub hole forming part (2) of the wheel disc. FIG. 3 is a detailed view of a portion forming the concave ring portion (5 ′) of FIG. 2, in which a plurality of slits (s) are provided along the lower periphery of the cylindrical portion (5), and thereby each piece is formed. It is divided so that it fits easily into the hub hole (4). FIG. 4 shows the wheel cover (1) separated from the fixing cap (3) so that they can be removed.

That is, a cylindrical body (7) having the same lower end as the cylindrical portion (5) shown in FIG. 3 is attached to the undercut portion (4 ′) of the hub hole forming portion (2) of the wheel disc. , The screw part (1a) provided on the inside of the cylindrical body (7) is screwed onto the screw part (1a ') provided on the outside of the separately provided central piece (8), and Attach the lower edge of the wheel cover (1) to the step (9) provided on the outside, and then attach the screw (2a) provided inside the tubular body (6) of the fixing cap (3) to the cylindrical body ( Screw it onto the screw part (2a ') provided on the outside of 7), and fix it by covering the upper edge of the wheel cover (1) with the hanging part (10) provided on the outer periphery of the fixing cap (3). To do. FIG. 5 [FIG. 6B-B 'cross-sectional view] shows an example in which the fixing cap (3) is fixed to the cylindrical body (7') of the wheel cover (1) without screwing the screw. Are fixed to the cylindrical body (7 ') with screws (12), but they may be originally constructed integrally. The hump portion (H) of the wheel rim (R) shows the state in which the tip portion (1 ') of the wheel cover (1) is locked. In addition, (d) shows a valve hole provided in the wheel cover (1). In this example, the hanging portion (10 ') provided on the fixing cap (3) is engaged with the outside of the rising portion (11) of the wheel cover (1) to secure the fixing. In addition, (6 ') indicates a rib provided on the cylindrical body portion (6). (2 ') is a hub hole forming part provided in the wheel disk of other dimensions.

[0008]

[Effect of the device]

 In this invention, when the wheel cover is attached to the wheel disc, the constituent parts of the wheel cover are directly fixed to the inner wall of the central hub hole, and the fixing cap is secondarily fixed. It is fixed firmly enough, and there is no danger of the wheel cover falling off, especially when the vehicle is traveling at high speeds or on rough roads. Also, by reasonably simplifying its configuration, it can be easily attached and detached.
