Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a wheel step for an automobile, which is attached to a disc wheel of the automobile and is used by a driver to step on and off the vehicle. is there.

[Conventional technology]

The wheel step for an automobile comprises an annular step body having a step seat on the outer peripheral surface and step fixing means for fixing the annular step body to the disc wheel. The step fixing means positions the step body on the disc wheel. It comprises a positioning member and a mounting seat through which a mounting bolt having a hook portion hooked in the notch of the disc wheel penetrates and which fixes the protruding end with a nut. In the prior art, the mounting seat was fixedly mounted by welding or the like across the step seat and the positioning member.

[Problems to be solved by the device]

However, in such a structure, since the mounting seat is welded after the step body is formed by bending, there is a drawback that the number of manufacturing processes increases and the manufacturing becomes expensive.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wheel step for an automobile, which avoids the above-mentioned drawbacks and allows the mounting seat to be formed simultaneously with the molding of the step body without the need for welding the mounting seat.

[Means for Solving the Problems]

In order to solve the above problems, the present invention comprises an annular step body having a step seat on the outer peripheral surface, and a step fixing means for fixing the annular step body to a disc wheel. In a wheel step for an automobile, which is composed of a positioning member for positioning the main body on the disc wheel and a mounting seat through which a mounting bolt having a hook portion hooked in a notch of the disc wheel penetrates and a protruding end is fixed with a nut, the mounting seat is The present invention provides a wheel step for an automobile, characterized in that the step step seat is integrally formed by bending.

[Action]

Thus, when the mounting seat of the step fixing means is formed by bending integrally with the step seat, it can be formed at the same time as the bending forming of the step body, so that the wheel step can be manufactured by a simple process at low cost. You can

〔Example〕

An embodiment of the present invention will be described in detail with reference to the drawings.
The figure schematically shows an entire vehicle wheel step 10 according to the present invention, which is mounted on a disk wheel 14 fixed to a wheel hub 12 by mounting bolts 13.

As shown in FIG. 1, the wheel step 10 comprises an annular step body 18 having a step seat 16 on its outer peripheral surface, and step fixing means 20 for fixing the annular step body 18 to the disc wheel 14. . Step fixing means
20 is a step body 18 as shown in FIG. 1 and FIG.
Positioning member 22 for positioning the
Then, a plurality (three in the drawing) of mounting bolts 24, which will be described later, penetrate the disk wheel 14 by the mounting bolts 24.
And a plurality of mounting seats 26 fixed to the. The mounting bolt 24 has a hook portion 24a hooked to the notch 14a of the disc wheel 14, and the end of the mounting bolt 24 on the side opposite to the hook portion 24a penetrates the mounting seat 26, and its protruding end. 24b is tightened by a nut 28 to fix the step body 18 to the disc wheel 14.

Each mounting seat 26 is formed by continuously bending the outer edge of the step seat 16 integrally. In the illustrated embodiment, 3
The two mounting seats 26 are provided at intervals in the circumferential direction of the step body 18, but may be provided continuously in the circumferential direction. The disc wheel 14 is attached to the inner edge of the mounting seat 26.
Has a joining piece 26a joined to a part of the. In this way, the mounting seat 26 can be formed simultaneously when the step body 18 is formed by bending.

In the embodiment shown in FIGS. 1 and 2, the positioning member 22 comprises a guide seat 30 integrally formed by bending on the inner edge of the step seat 16 so as to be joined to the inclined surface 14b of the disc wheel 14. There is. Therefore, in this example,
The guide seat 30, the step seat 16, and the mounting seat 26 are integrally formed so as to have a substantially triangular cross section.

As already mentioned, the step body 18 is formed integrally by bending the step seat 16 and the positioning member 22.However, if the mounting seat 26 is also formed integrally by bending the step seat 16 as described above, Seat 16, positioning member
It can be seen that all 22 and the mounting seat 26 are bent and formed at the same time, which facilitates manufacturing.

In addition, the positioning member 22 is the inclined surface 14b of the disc wheel 14.
When integrally formed by bending the inner edge of the step seat 16 so as to be joined to, a mounting plate that joins the disk wheel 14 in a large area is unnecessary, and the guide seat 30 that constitutes the positioning member 22 is Disc wheel
Since it has the functions of both the joint surface with 14 and the guide surface, the structure is simple, which is preferable.
As shown in FIG. 3, a plurality of (for example, four) mounting ears 32 joined to the disc wheel 14 and a bending piece 34 that folds the inner edge of the mounting ears 32 and engages with the inner edge of the disc wheel 14. May consist of These mounting ears 32 are provided off the mounting bolts 13 for mounting the disc wheel 14 on the axle hub 12.

[Effect of device]

According to the present invention, as described above, the mounting seat of the step fixing means is formed by bending integrally with the step seat, so that the mounting seat can be formed at the same time when the step body is formed by bending, and thus the wheel step can be formed. There is a real advantage that it can be manufactured at low cost by a simple process.
