Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a vehicle wheel on an axle.

[0002]

2. Description of the Related Art Conventionally, as a structure for mounting a wheel of a vehicle, for example, a passenger car to an axle, one shown in FIGS. 3 to 5 is known (for example, Japanese Utility Model Laid-Open No. 4-287702). In FIGS. 3 to 5, reference numeral 1 denotes a wheel, which is composed of a tire 2 and a wheel 3, and the wheel 3 has a hub 6 at the center of a wheel disc portion 5 having a rim peripheral portion 4 on which the tire 2 can be fitted. The hub hole 7 is provided with four mounting holes 8 (also referred to as lug holes) on the outer peripheral side thereof, and an outer taper 8A is provided on the wheel outer side of the mounting holes 8.

Reference numeral 9 is an axle, and a brake disk 10 is provided at the end of the axle.
A rotor (wheel mounting portion) 11 is provided, and four wheel mounting screws 12 are provided on the outer surface of the rotor 11 so as to project on the same circumference at equal pitches, and the shaft end 9A projects at the center of the end surface of the rotor 11. ing. And when installing the wheel 3,
As shown in FIG. 4, the mounting screw 12 is mounted in the mounting hole 8 provided in the hub 6 of the wheel 3 and the shaft end 9A is mounted in the hub hole 7 thereof.
Is abutted on the rotor 11 so that it fits in, and the tapered wheel nut 13 is screwed onto the screw 12. In addition, 14 is a suspension.

[0004]

[Problems to be Solved by the Invention] By the way, the wheel 3
When machining the mounting holes 8 in the hub 6, it is difficult to position the centers of the holes 8 on the same circumference, and eccentricity or the like is likely to occur. In addition, the repair aluminum wheel, as shown in Fig. 4, has a shaft end 9A so that it can be mounted on the vehicle of each automobile manufacturer.
The diameter D of the hub hole 7 is set to be larger than the outer diameter d of the hub hole 7, and a gap is generated between the hub hole 7 and the shaft end 9A.

Therefore, when mounting the wheel 3, the wheel nut 13 is often centered only by tightening, and as shown in FIG. 5, the axle center CS and the wheel center CW are easily eccentric, resulting in eccentricity. There is a problem that the tire 2 is shaken and the vehicle is vibrated when traveling at high speed to make the riding comfort worse. The present invention has been made in view of the above problems, and an object of the present invention is to enable accurate wheel mounting without eccentricity between the axle center and the wheel center and to improve workability. It is possible to provide a vehicle wheel mounting structure capable of reducing the vibration of the vehicle.

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention provides a wheel having a hub at the center of a wheel disc portion having a rim peripheral portion on which a tire can be fitted, a wheel mounting portion provided at an end portion of an axle via a mounting screw and a wheel nut. A structure for mounting is characterized in that a wheel centering ring is fitted between the hub hole of the wheel and the outer end of the axle.

Further, the present invention is characterized in that a female screw is provided in the hub hole of the wheel, a male screw is provided on the outer periphery of the ring, and the ring is screwed into the hub hole.

[0008]

According to the present invention, when the centering ring is fitted in the hub hole of the wheel, the ring is fitted to the shaft end, and the wheel nut is screwed to the mounting screw, the wheel is Since it is centered via the ring and is constrained to the vehicle end via the ring, eccentricity between the shaft center and the wheel center does not occur.

Therefore, by preparing the centering rings whose inner diameters correspond to the shaft end diameters of the respective vehicle manufacturers, it is possible to deal with the automobiles of the respective vehicle manufacturers. By making the centering ring fittable into the hub hole of the wheel, the workability of mounting the wheel is improved.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an essential part of an embodiment of the present invention, but since the basic structure of the axle 9 and the wheel 3 of the vehicle is the same as that shown in FIGS. 3 and 4, the common structure is shown in FIG. , The same reference numerals as those in FIG. 4 are attached, and the characteristic part of the present invention will be described in detail.

In FIG. 1, 3 is a wheel, 5 is a wheel disk portion, 6 is a hub, 15 is a hub hole, 8 is a mounting hole, and 8A.
Is a taper portion, 9 is an axle, 9A is an outer end portion of an axle, 10 is a brake disc, 11 is a wheel mounting portion, 12 is a mounting screw, 13
Is a wheel nut, and 16 is a centering ring.
The hub hole 15 is a threaded hole in which a female screw is cut. A male screw 17 is provided on the outer periphery of the centering ring 16 as shown in FIG. 2, so that the ring 16 can be screwed into the hub hole 15. Has become. The inner diameter DO of the ring 16 is set to a size that allows the ring 16 to be removably fitted in the axle outer end 9A, and can be fitted to each axle outer end of the vehicle of each vehicle manufacturer in a corresponding manner. A large number of various sizes are prepared, and consideration is given so that wheels can be attached to each car.

In the above embodiment, when the aluminum wheel 3 or the like is attached to the outer end 9A of the axle 9, the outer end 9A of each axle is
A centering ring 16 with an inner diameter that can be fitted to is screwed into the hub hole 15 of the wheel 3 so that each screw 12 corresponds to the mounting hole 8 and the outer end 9A has a hole 16A in the ring 16. By aligning and fitting each other, the center CW of the wheel 3 is aligned with the axle center CS, and centering is performed accurately.

Therefore, by screwing the wheel nut 13 onto the mounting screw 12, the wheel 3 can be easily and accurately mounted on the mounting portion 11 of the axle 9. When tightening the wheel nut 13, even if the machining center position or pitch of the mounting hole 8 is slightly off the center of the mounting screw 12,
Since 3 is constrained to the axle outer end 9A via the centering ring 16, the wheel 3 does not move in the radial direction to cause eccentricity, and the centering accuracy is maintained.

Further, by preparing the centering ring 16 having the inner diameter corresponding to the axle of each vehicle manufacturer, the wheel 3 can be easily and accurately attached to each vehicle only by selectively screwing the ring 16. Therefore, the vibration of the vehicle during high-speed traveling can be significantly reduced by eliminating the vibration of the tire. The present invention is not limited to the above-described embodiment, and for example, the male thread 17 is not provided on the outer circumference of the centering ring 16 so that the centering ring 16 can be fitted into a conventional hub hole. It is possible to appropriately change the design such as providing an outward flange on the outer end of 16 or providing a turning tool engaging recess.

[0015]

As described above, according to the present invention, a wheel having a hub at the center of a wheel disk portion having a rim peripheral portion into which a tire can be fitted is attached to a wheel mounting portion provided at an end portion of an axle. A structure for mounting via a mounting screw and a wheel nut, characterized in that a wheel centering ring is fitted between the hub hole of the wheel and the outer end of the axle. Wheels can be centered easily and accurately, eccentricity of the wheels can be prevented to prevent tire runout, vibration of the vehicle at high speeds can be reduced, and ride comfort of the vehicle can be improved. It is easy to deal with vehicles of each vehicle manufacturer.

Further, according to the present invention, a female screw is provided in the hub hole of the wheel, a male screw is provided on the outer periphery of the ring, and the ring is screwed into the hub hole. It is possible to improve the workability of wheel mounting.
