Abstract

(57) [Abstract] [Purpose] The present invention relates to an automobile wheel in which a spacer for adjusting an offset amount is interposed between a hub of an axle and a disc wheel. [Structure] Disc wheel 1 for axle hub 14
When installing the hub 14 and the disk wheel
In a vehicle wheel in which a spacer 4 is interposed between the bolt 1 and the wheel 1, a plurality of bolt insertion holes 3 are provided concentrically around the hub hole 2 of the disk wheel 1. The spacer 4 having a screw hole 5 communicating with the screw hole 5 and a stud bolt through hole 6 formed between the screw holes 5.
On the mounting surface 7 that abuts the disk wheel 1, a projecting edge 8 that closely fits into the groove 9 formed in the opening of the bolt insertion hole 3 is provided so as to surround the screw hole 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle wheel in which a spacer for adjusting an offset amount is interposed between an axle hub and a disk wheel.

[0002]

[Prior art]

 In automobile wheels, the dimension between the disc wheel attachment surface to the axle hub and the rim centerline, that is, the amount of offset, varies depending on the manufacturer and vehicle model. In order to meet this demand, a spacer having an appropriate thickness is interposed between the hub and the disc wheel as a means for achieving this.

[0003]

[Problems to be solved by the device]

 By the way, a conventional spacer of this type has a stud bolt further protruding from the spacer, which is different from the original stud bolt itself which comes out from the vehicle side. Since the structure is such that the bolt is taken out and the wheel is tightened with the stud bolt and nut, it is considered that the stud bolt is relatively affected by the inertia moment, and this point requires a solution. Is.

[0004]

[Means for Solving the Problems]

 That is, the present invention relates to a vehicle wheel in which a spacer is interposed between the hub and the disc wheel when mounting the disc wheel to the hub of the axle as described above. It has screw holes that are in communication with every other bolt insertion holes provided concentrically around the hub hole of the disc wheel, and through holes for stud bolts formed between these screw holes. On a mounting surface of the spacer that abuts the disk wheel, an automobile wheel is provided with a projecting edge that closely fits in a groove formed in the opening of the bolt insertion hole and surrounds the screw hole. -Proposes the following.

[0005]

[Action]

 In the vehicle wheel of the present invention having the above-mentioned structure, in the spacer and the disc wheel, the projecting edge formed in the former abuts and is joined in the concave groove formed in the latter. Therefore, it is possible to avoid rattling at the time of power transmission and to avoid an adverse action due to inertia moment.

[0006]

【Example】

 1 to 3, FIG. 1 is a sectional view showing a state in which a spacer is coupled to a disc wheel, FIG. 2 is a left side view (a view from the inside of the vehicle body) of FIG. FIG. 2 is a right side view (a view seen from the outside of the vehicle body) with a part of FIG. 1 omitted.

In FIG. 1, reference numeral 1 denotes a disc wheel. Around the hub hole 2 of the disc wheel 1, a large number of bolt insertion holes 3 are provided concentrically with the hub hole 2 at equiangular intervals. (See Figure 3).

A spacer 4 for adjusting the offset amount with respect to the center line 0-0 of the disk wheel 1 will be described with reference to FIG. In this spacer 4, there are provided screw holes 5 communicating with every other bolt insertion hole 3 of the disk wheel 1, and through holes 6 for stud bolts which are formed between these screw holes 5 and which will be described later. Is provided.

A projecting edge 8 is formed so as to surround the screw hole 5 on a mounting surface 7 of the spacer 4 that abuts the disk wheel 1, and with this, the disk wheel 1 is projected. -The bolt insertion hole 3 of the rule 1 is provided with a concave groove 9 into which the projecting edge 8 is tightly fitted.

On the other hand, the stud bolt insertion hole 6 of the spacer 4 communicates with a large-diameter space 10 opening in the mounting surface 7, and the head 12 of the stud bolt 11 is located in the space 10. Is accommodated.

FIG. 2 shows the relationship between the disc wheel 1 and the spacer 4, and the screw hole 5 and the stud bolt insertion hole 6 are shown on the spacer 4. In FIG. 2 and FIGS. 1 and 3, 13 indicates a color.

In the above-mentioned structure, the spacer 4 is first coupled to the hub 14 of the axle by the stud bolt 11, and then the concave groove 9 of the disc wheel 11 is fitted into the flange 4 of the spacer 4. With the 8 tightly fitted, the wheel mounting bolt 15 is screwed into the screw hole 5 and tightened.

With such a structure, when the wheel is driven, the spacer 4 and the disc wheel 1 perform power transmission in a tightly fitted state with the projecting edge 8 in the concave groove 9. Is possible.

[0014]

[Effect of device]

 According to the vehicle wheel of the present invention having the above-mentioned structure, it is possible to reduce the influence of inertia moment and to transmit the rotational driving force to the wheels, as compared with the conventional type spacer. Can be achieved reliably and safely.
