Description

Detailed Description of the Invention TECHNICAL FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel balance weight mounted on a rim flange portion of a wheel in order to balance the wheel of an automobile.

[0002]

2. Description of the Related Art An automobile wheel makes a circular motion around an axle shaft. However, if the wheel balance is out of order, vibration occurs as the rotation speed increases. Therefore, the balancer is used to find a part with a light wheel balance, and the wheel balance weight is driven into this part to be mounted to achieve the wheel balance.

Conventionally, the wheel balance weight is formed of a lead member having a large weight (large specific gravity) instead of a volume. That is, as shown in FIG. 11, the wheel balance weight includes a wheel balance weight main body (hereinafter referred to as a weight main body) 11 made of a lead member, and an attachment clip 19 integrally fixed to the weight main body 11. As shown in FIGS. 11B and 12, the weight main body 11 is attached.
Is attached to the inner peripheral surface F1 of the rim flange portion F, and the mounting clip 19 portion is attached to the outer peripheral surface F2 of the rim flange portion F.
In addition, the weight body 11 and the mounting clip 19 are positioned such that the end portion of the rim flange portion F is sandwiched between them, and are hammered in and attached.

Further, as shown in FIG. 13, the weight body 1
1 and the mounting clip 29 are separately configured to attach the weight main body 11 to the inner peripheral surface F1 of the rim flange portion F, and the mounting clip 29 has the mounting clip 29.
29a of the weight of the weight body 11 and the other end 29b
Is mounted so as to be engaged with the outer peripheral surface F2 of the rim flange portion F.

In this case, since the lead member of the weight body 11 is a soft member, it is deformed along the radius R of the wheel W by the driving. As a result of this deformation, the wheel W is "familiar" with the wheel W and is unlikely to come off after mounting, and the wheel W is not damaged even when driving. Furthermore, even if the R diameter of the wheel W is different,
Since the weight main body 11 bends along the different R diameters, it is not necessary to prepare the wheel balance weight for each different R diameter of the wheel W.

[0006]

As described above, the wheel balance weight made of the lead member has good compatibility with the R diameter of the wheel, is hard to come off after mounting, does not damage the wheel, and further has the R diameter of the wheel W. It has the convenience that it is not necessary to prepare wheel balance weights corresponding to each different, but this lead member has lead poison, and its use will be restricted in the future due to problems such as pollution. May occur. Therefore, it is necessary to consider using a metal member other than lead, such as an iron member, as the wheel balance weight member. However, since the iron member or the like is not as soft as the lead member, it does not deform along the R diameter of the wheel W even if the driving is performed, and it does not fit in. Therefore, there is a risk that it will come off after mounting. Further, if the driving is forcibly performed, the wheel may be damaged. This is a particular problem in the case of aluminum wheels that are soft in terms of materials.

Further, since a metal member such as an iron member is hard and lacks in flexibility, it is not deformed along the R diameter of the wheel W and does not "fit into", so that it is shown in FIGS. 14 (a) and 14 (b). If the R diameter of the wheel W and the R diameter of the weight main body 11 do not match as described above, a gap is generated between the wheel W and the weight main body 11, which may cause backlash or dust intrusion. However, there is also a disadvantage that various wheel balance weights suitable for the size of each wheel W must be prepared. In FIG. 14, (a) shows the case where the R diameter of the weight body 11 is smaller than the R diameter of the wheel W,
(B) is a case where the R diameter of the weight body 11 is larger than the R diameter of the wheel W.

The present invention was devised in view of such problems, and even if the wheel balance weight is formed of a metal member such as an iron member, which is not as flexible as a lead member, it is attached. It has good compatibility with the R diameter of the wheel and can cope with different R diameters of the wheel, provides a wheel balance weight that does not easily come off after mounting, and does not damage the wheel at the time of mounting. It is an object of the present invention to provide a wheel balance weight that can be used in place of the wheel balance weight formed of a member.

[0009]

In order to achieve the above-mentioned object, the wheel balance weight of the present invention constitutes a small weight body which is a weight body formed by connecting a plurality of weight balance bodies. The small weight body can be connected by a connecting means. It is characterized in that a plurality of the small weight bodies are connected to form a weight body having a predetermined weight.

In the weight body constructed by connecting a plurality of the small weight bodies, if flexibility is imparted in the connecting means, even if the small weight bodies are formed of a hard metal member, for example, an iron member, a wheel. It is preferable because it can be fitted to the user easily. By doing so, the small weight body can be configured by a metal member or a compounding member of metal and rubber and / or resin, and it is possible to avoid the use of the lead member and prevent lead damage. However, even if it is configured with such a member, it can be fitted to the wheel and can be fitted even if it is different from the R diameter of the wheel, it does not easily come off even after the fitting, and the wheel is not damaged at the time of fitting.

Specifically, the small weight body has a screw hole formed in one end surface and a screw shaft projecting from the other end surface, and adjacent small weight bodies have the same screw hole in one small weight body. The small weight body is screwed into and connected to form a weight body, or the small weight body is provided with a through hole, and the small weight body is inserted into the shaft member through the through hole to form a plurality of through holes. There may be mentioned a structure in which the weights are connected to each other to form a weight body.

Further, the small weight body is provided with a through hole, and the small weight body is inserted into the shaft member through the through hole to connect a plurality of members to form a weight body, while the mounting clips are opposed bearings. It is possible to cite a configuration in which the weight main body including a plurality of parts is located between the bearing parts of the mounting clip that face each other, and both ends of the shaft member are fixed to the bearing part. According to this structure, the weight body can be formed by connecting and fixing the plurality of small weight bodies together, and
At the same time, a mounting clip can be provided on the weight body formed by connecting a plurality of small weight bodies.
