Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a disc wheel for an automobile, and in particular, the invention relates to a disk wheel for an automobile, and in particular, the bolt position pitch which determines the attachment position of a hub bolt attached to the hub of an automobile has a different diameter. This invention relates to a disc wheel that can be attached to many types of automobiles.

[Prior Art] Conventionally, disc wheels for automobiles have a hole formed on a nut seat pitch circle with a diameter matching the diameter of the bolt position pitch circle, and a bush for receiving a lug nut is press-fitted into the hole. .

However, in the above-mentioned conventional disc wheel, the position of the bushing is fixed on a predetermined nut seat pitch circle, so it cannot be installed on a car where the diameter of the nut seat pitch circle is different from the diameter of the bolt position pitch circle. There's a problem. Therefore, it is necessary to produce several types of disc wheels with different nut seat pitch diameters for one size disc wheel, which deteriorates productivity. In addition, since demand varies depending on the size of the nut seat pitch circle diameter, production adjustment becomes complicated and tends to result in overstocks or shortages.

Furthermore, although the vehicle manufacturer's genuine automobile disc wheels have a fitting method in which the inner diameter of the center hub hole and the outer diameter of the vehicle's hub cap fit together, disc wheels sold individually on the market do not fit in this direction. This caused vibrations during high-speed driving due to unbalance at the rear of the vehicle.

[Problems to be solved by the invention] The invention improves the versatility of automobile disc wheels by allowing them to be installed on many types of automobiles with different bolt positions and pitch diameters, and also increases their productivity. The problem to be solved is to facilitate production adjustment.

Further, the problem to be solved is to provide a fitting means to prevent misalignment of the axis when mounted on a vehicle, and to make it possible to suppress the occurrence of unbalance as much as possible.

Furthermore, it is an object of the present invention to provide an automobile disc wheel that solves the above-mentioned problems and has a structure that is easy to handle.

[Means for Solving the Problems] A means for solving the above problems in the present invention is to provide a plurality of long holes for hub bolts extending in the radial direction from the center hub hole in the disc portion of the wheel. A groove is formed on the inner surface of the elongated hole, and the flange of the flanged bushing is inserted into the groove to allow movement in the radial direction, and the flange is provided on both the outer diameter of the vehicle's hub cap and the inner diameter of the center hub hole of the wheel. To provide an automobile disc wheel in which a hub fitting collar to be fitted is provided in a center hub hole.

[Function] The bush built into the long hole for the hub bolt is
Since the flange is slidably inserted into the groove, the bush can be moved in the radial direction, that is, in the radial direction of the wheel, along this elongated hole. can be adjusted. Therefore, it can be installed in many types of automobiles having different bolt position pitch circle diameters.

In addition, since the hub fit collar provided in the center hub hole is fitted into the center hub hole, it is possible to prevent the bush inserted into the elongated hole groove from falling out. Since the part can be fitted and mounted on the outer diameter part of the hub cap of the vehicle, misalignment of the axis can be suppressed as much as possible.

As for the inner diameter dimension of the hub fit collar, it is necessary to match it to the vehicle in which it is installed, so you can set up many different types of hub fit collars and rearrange them, or you can use a thick hub fit collar. It is also possible to incorporate the collar in advance and process it to fit the outside diameter of the hub cap of the vehicle when it is installed in the vehicle.

In any case, the versatility of the disc wheel is ensured. Furthermore, by integrating the disc wheel body, bushing, and hubfit collar as described above, handling is convenient.

[Example] As shown in FIGS. 1 and 2, this disc wheel 1 has four bush slide holes 3 (for the hub bolts described above) extending radially from the center hub hole 2 provided in the center. A long hole) is formed. A groove 4 is formed on the inner surface of the bush slide hole 3.

The flange 8 of the bush 6 is inserted into the groove 4 and is slidable in the radial direction in which the bush slide hole 3 extends. Therefore, by sliding the bush 6 along the bush slide hole 3, the nut seat pitch diameter R (see FIG. 4) can be adjusted in accordance with the bolt position pitch diameter of the automobile hub to be attached.

In addition, the center hub hole 2 which is the hub side of the car
A slightly larger chamfered portion is formed at the end portion.

Reference numeral 9 shown in FIGS. 3 and 4 is a hub fit collar press-fitted into the center hub hole 2, and the hub cap 10 (see FIG. 4) is fitted into the center hub hole 2.
This is for a tight fit inside. An overhang 11 is provided at one end of the hub fit collar 9.
(See Fig. 4), and this projecting portion 11 is engaged with the chamfered portion 5 of the center hub hole 2, so that the hub fit collar 9 slips out toward the surface side of the disc wheel 1 during high-speed rotation. It seems like there is no such thing.

In order to make this disc wheel 1 versatile, it is necessary to make the center hub hole 2 slightly larger so that it can be applied to hub caps 10 of various outer diameters. In addition, hubfit collars 9 of various thicknesses are prepared, the hubfit collars 9 are provided according to the outer diameter of the hubcap 10, and the hubcap 10 is fitted into the center hub hole 2. This makes it easy to center the hub of the vehicle and the disc wheel 1, and to prevent vibrations during high-speed driving.

Furthermore, by providing this hub fit collar 9, it is possible to prevent the collar portion 8 from slipping out from the groove portion 4 into the center hub hole 2, and the lug nut 7 (see Fig. 4) can be removed to remove the disc. wheel 1
This is preferable because the bushing 6 will not fall off when removed from the vehicle.

When mounting the present disc wheel 1 on a car, insert the bush 6 into the bush slide hole 3 from the center hub hole 2 side by inserting its flange 8 into the groove 4, and then insert the bush 6 into the bush slide hole 3 from the center hub hole 2 side. is press-fitted into the center hub hole 2.
The bush 6 can slide in the radial direction along the bush slide hole 3 while sliding the flange 8 within the groove 4, thereby adjusting the nut seat pitch circle diameter R (see Fig. 4). Can be adjusted.

In the above embodiment, four bush slide holes 3 are provided, but an automobile usually has four or five hub bolts, and the number of bush slide holes 3 also varies depending on the number of hub bolts. Just set it.

[Effects of the invention] According to the invention, the nut seat pitch circle diameter can be adjusted to match the bolt position pitch circle diameter, so one type of disc wheel can be applied to many types of automobiles with different bolt position pitch circle diameters. It becomes like this. Therefore, the number of types of disc wheels to be manufactured can be significantly reduced, productivity can be improved, and production adjustment can be simplified.
In addition, by using a hubfit collar,
It prevents the bushings from falling off and makes handling the wheels easier.Furthermore, by minimizing misalignment of the shaft center, the amount of unbalance is reduced, eliminating steering vibration at high speeds and providing a comfortable drive. It happens.
