[Industrial applications]

 The present invention relates to a center cap mounting bracket for mounting a center cap on a wheel used for a truck or a bus among automobile wheels, a center cap including the bracket, and a mounting structure thereof.

[0002]

[Prior art]

 Conventionally, the center caps of wheels used for trucks and buses have been tapped around the hub holes of the wheel discs and screwed directly to the wheels, or hub cap fixing bolts attached to the tip of the axle have been used. Then, it is proposed that the hub cap is fastened with a nut via a bracket with a bolt, or the hub nut that fixes the wheel together with the wheel and the wheel cover is tightened together (Japanese Utility Model Laid-Open No. 2-77105 and Japanese Utility Model Laid-Open No. 2-107105). 77104).

[0003]

[Problems to be solved by the device]

 Among the above-mentioned conventional techniques, the one in which the wheel disc is tapped and directly screwed requires tapping on the wheel disc in advance, which increases the number of machining steps and also causes the wheel to be tapped from the automobile for tapping. It had to be removed. For this reason, it took a lot of time and effort for installation work, and the coating on the wheel surface was peeled off during tapping, which necessitated re-painting. Next, in the case of fixing to the hub cap via a bracket, the hub allowance varies depending on the vehicle model and manufacturer, and the number of bolts for mounting the hub cap also differs, so a large number of each center cap and bracket are available. It was necessary and complicated for parts management. Also, in the case where the hub nuts are used to fix the wheels together, the wheel nuts are provided on the wheel cover and center cap, respectively, so the hub nuts are less likely to engage with the wheels, which may cause the hub nuts to loosen during travel.

The present invention has been made in order to solve the above-mentioned problems of the prior art, requires only a small number of center caps, can be easily mounted without loosening the hub nut for wheel mounting, and can be reliably mounted. An object of the present invention is to provide a center bracket mounting bracket that can be fixed, a center cap equipped with the bracket, and a mounting structure thereof.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in the bracket for mounting a center cap of an automobile wheel of the present invention, a substantially rectangular plate-shaped mounting body is vertically installed inside the base of the engaging claw that is substantially inverted L-shaped. A gap is provided between the inner end surface of the compound jaw except the base and the mounting body. Further, in order to easily attach the bracket to the center cap, to insert the engaging claws easily, and to improve elastic retention, it is preferable that the outer end surface of the engaging claws and the mounting body are curved in an arc shape. Further, in order to prevent loosening due to vibration of the automobile, a cushioning material may be attached to the back surface and / or the outer end surface of the engaging claw of the bracket. Further, the center cap of the present invention has at least two brackets spaced from each other on the cap body having a substantially bottomed cylindrical shape so that the engaging claws project outward from the opening. A bracket mounting body is fixed to the inner surface of the part. The center cap is attached to the wheel by inserting the engaging caps of the center cap into the gaps between the wheels and the undersides of the heads of the hub nuts that secure the wheels. It is fixed by elastic deformation of the nail. Furthermore, if the fixing plate is fitted in the gap of the bracket formed between the inner end surface of the engaging claw and the mounting body, the inward deformation of the engaging claw can be restricted, and the center cap can be controlled by the wheel. It can be installed firmly.

[0006]

The wheel of a truck or a bus is normally fixed to the axle by using 6 to 10 hub nuts by the contact between the spherical portion of the hub nut and the nut seat of the wheel. There is a gap between the underside of the hexagon head of the hub nut and the wheel. When the center cap of the present invention is rotated by abutting on the wheel so that the bracket is located between arbitrary hub nuts, the engaging claws of the bracket are fitted into the above-mentioned gap. Then, due to the contact between the outer end surface of the engaging claw and the lower surface of the head portion of the hub nut, the engaging claw elastically deforms in the radial direction, and the center cap has at least two engaging claws in one wheel. The hub nuts are engaged and fixed.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

Referring to FIG. 1, a bracket 1 of the present invention comprises a metal plate, particularly an engaging claw 2 formed in a substantially inverted L shape using spring steel, and a substantially rectangular plate-shaped mounting body 3. 2 and a part of the long side of the mounting body 3 are integrally formed so as to be substantially at right angles, and a required gap g is provided between the inner end surface of the engaging claw 2 excluding the base portion and the end surface of the mounting body 3. It will be done. The outer end surface of the engaging claw 2 is formed in a substantially linear shape, but may have a diameter substantially the same as or slightly larger than the diameter of an imaginary circle inscribed with the undersides of the heads of the hub nuts to which the wheels are fixed. In some cases, the contact portion 4 is formed as described above.

The mounting body 3 is formed by forming screw holes 5 at both ends thereof and screwing countersunk screws 6 therein. Further, when the mounting body 3 is curved in an arc shape so as to follow the inner surface shape of the opening of the center cap, mounting on the center cap becomes easy. The screw hole 5 and the countersunk screw 6 of the mounting body may be omitted.

By the way, a cushioning member 7 made of an elastic member such as rubber, sponge or synthetic resin is provided on the contact portion 4 of the engaging claw 2 of the bracket 1 and the rear surface of the engaging claw 2 which is a contact surface with the wheel. If the bracket is formed with an adhesive or coating, it is possible to more reliably prevent the bracket from loosening and the center cap from coming off due to the vibration of the vehicle.

In FIG. 2, reference numeral 8 denotes a center cap. This center cap 8 has a pair of screw holes at a required interval at the opening end of a cap body 9 having a substantially bottomed cylindrical shape. Both sets are drilled. Then, the mounting body 3 of the bracket 1 is brought into contact with the inner surface of the opening end of the cap body 9, and the dish screws 6, 6 screwed to the mounting body 3 are inserted through the screw holes at the opening end to insert the nuts. Stick with 10. Therefore, the engaging claw 2 of the bracket projects outward of the opening of the cap body 9, and the gap g of the bracket constitutes the center cap 8 located outside the opening end.

By the way, as for a wheel of a truck or a bus, a front wheel is usually a single wheel and a rear wheel is a double wheel, and a wheel outside the rear wheel is attached to the front wheel in the opposite direction. In addition, since the hub cover is protruding from the rear wheel, a deep center cap is required. Therefore, also in this embodiment, as shown in FIGS. 2A and 2B, a shallow one for the front wheels and a deep one for the rear wheels were manufactured. In the above embodiment, when the screw hole 5 and the countersunk screw 6 of the bracket mounting body are omitted, the bracket and the cap body are integrally fixed by rivets or spot welding.

At this time, as for the relationship between the hub nut and the wheel, as shown in FIG. 4, the spherical seat of the hub nut 12 is fixed in contact with the nut seat of the wheel 11, but the head lower surface 13 of the hub nut 12 and the wheel 11 are fixed. A gap 14 is formed between them. Therefore, the center cap 8 is brought into contact with the wheel 11 so that the bracket 1 is located between the adjacent arbitrary hub nuts 12, 12. Then, the center cap 8 is rotated so that the engaging claws 2 of the bracket 1 enter the gaps 14, respectively. As the approach is advanced, the engaging claws 2 enter in the radial direction, and the relative pitch of the claws of the center cap 8 changes to decrease, and the elastic deformation of the engaging claws 2 makes the center cap 8 easy. Can be fixed to.

By the way, it is desirable to provide the fixing plate 15 in the gap g of the bracket 1 in order to regulate the change of the engaging claws due to the vibration while the automobile is running. That is, the fixing plate 15 is curved and formed in an arc shape so as to come into contact with the outer surface of the center cap 8, and the center cap is attached to the wheel while being temporarily tightened to the countersunk screw 6 provided on the center cap 8. After mounting, finally, the fixing plate 15 is fitted into the gap g between the center cap 8 and the engaging claw 2 of the bracket 1, and the nut 10 is tightened and fixed. By providing this fixing plate 15, it is possible to completely prevent the center cap 10 from coming off due to vibration while the vehicle is running. In the above embodiment, the fixed body was attached using the countersunk screw of the bracket, but it may be attached by bolts and nuts that are separately provided on the center cap or screwed holes and bolts that are formed in the center cap. It is possible. In addition, an elongated hole may be provided in the fixing portion of the fixing plate 15 so that the position can be adjusted in the circumferential direction.
