【考案の詳細な説明】
〈技術分野〉
この考案は、自動車用ステアリングホイールの
芯材に関する。[Detailed Description of the Invention] <Technical Field> This invention relates to a core material for an automobile steering wheel.
〈従来技術〉
ステアリングホイール用芯材のリング部は、一
般に中実の棒鋼を円形に曲折して使用されるが、
自動車の軽量化に伴ない、リング部芯金に中空の
管状部材が使用されはじめている。<Prior art> The ring portion of the core material for a steering wheel is generally made by bending a solid steel bar into a circular shape.
As automobiles become lighter, hollow tubular members are beginning to be used for ring cores.
そして、また、ステアリングホイール用芯材で
は、リング部芯金とスポーク部芯金の結合部に充
分な結合強度をもつことが要求されるが、価格
的、意匠的、強度的、或は軽量化のためにリング
部とスポーク部の芯材を異種金属又は異種材料で
作る必要がある場合、それらの結合部を溶接する
ことができないため、リング部芯金とスポーク部
芯金の結合は溶接以外で充分な強度の得られる嵌
合、かしめ、リベツト止めなど機械的結合を行な
わなければならない。 In addition, core materials for steering wheels are required to have sufficient bonding strength at the joints between the ring core metal and the spoke core metal, but there are other issues such as cost, design, strength, or weight reduction. If the core materials of the ring and spoke parts need to be made of different metals or materials for this reason, it is not possible to weld their joints, so the connection between the ring part core metal and the spoke part core metal must be made using methods other than welding. Mechanical connections such as fitting, caulking, riveting, etc. must be used to provide sufficient strength.
そこで、従来では、実公昭58−42225号公報に
おいて、鋼製で丸棒のリング部芯金に鋼製の結合
具を用いて軽合金製のスポーク部芯金を機械的に

め、この箇所のリング部に段差ができ、軟質被覆
層をこの周囲に形成した際、結合具の箇所に薄肉
部ができ、ステアリングホイールを握つた際に違
和感を与える問題があつた。 Therefore, in the past, Japanese Utility Model Publication No. 58-42225 proposed a method in which a light alloy spoke core was mechanically connected to a round ring core made of steel using a steel connector. However, since this connector is wrapped around the outer periphery of the ring core metal, there is a step in the ring section at this location, and when a soft coating layer is formed around this, a thin wall portion is created at the connector. There was a problem with this, which caused an uncomfortable feeling when gripping the steering wheel.
また、上記芯金が結合具のみにより連結される
ため、必要強度を得るためには結合具の形状を大
きくする必要があり、デザイン上の制約が生ずる
問題があつた。 In addition, since the core metals are connected only by the connector, the shape of the connector must be increased in order to obtain the required strength, which poses a problem in terms of design.
〈考案の目的〉
本考案は、上記の点にかんがみなされたもの
で、スポーク部芯材とリング部芯金が異種材料製
である場合にも、両芯材間の結合を充分な強度を

アリングホイール用芯材を提供することを目的と
する。<Purpose of the invention> The present invention was developed in consideration of the above points, and it is possible to maintain a bond between the spoke part core material and the ring part core material with sufficient strength even when the core material of the spoke part and the core metal of the ring part are made of different materials. An object of the present invention is to provide a core material for a steering wheel that can be reliably carried out and does not create defective shapes such as steps at the joint portion of a ring part.

リングホイール用芯材を構成した。<Structure of the invention> In order to achieve the above object, the present invention provides a ring part core metal formed hollow with a bottomed groove part connected to the longitudinal direction of the circumference, and a spoke part core in the bottomed groove part. At least the surface of the spoke core material is made of a material different from that of the ring core material, and a joining aid made of the same type of metal as the ring core material is mechanically attached to the tip of the spoke core material. A core material for a steering wheel was constructed by inserting the tip of the joining aid into the bottomed groove and welding the joint between the joining aid and the ring core metal.

とはその主要金属材料が同一で充分強度の得られ
る溶接が可能な金属をいう。 Fig. 1 shows a partial front view of the core material for a steering wheel, and Fig. 2 shows a cross-sectional view taken along the line A-A. It is formed all around. Bottomed groove part 2
is a groove with a rectangular cross section, and its width is formed to the extent that the tip of a spoke core material 3, which will be described later, can be inserted thereinto, that is, approximately the thickness of the spoke core material 3. 1 is manufactured by drawing and bending an aluminum pipe or an aluminum plate. 3
Each spoke core material 3 is formed by bending a strip-shaped steel plate into a predetermined shape as shown in FIG. The tip is inserted into the bottomed groove 2 of the ring core metal 1. 5 is a joining aid used for the joining part of the ring part core metal 1 and the spoke part core metal 3;
As shown in FIG. 5, the spoke part fixing part 5a is provided with a rivet hole for riveting to the back surface of the spoke part core material 3, and the spoke part core material 3 is attached to the bottomed groove part 2 of the ring part core metal 1. The ring part insertion part 5b is fitted on both sides of the ring part insertion part 5b.
is divided into two parts at the bottom of the spoke part fixing part 5a,
The joining aid 5 is formed by being slightly bent forward, and is made integrally by press working or the like using the same type of metal as the ring core metal 1. Note that similar metals refer to metals whose main metal materials are the same and which can be welded with sufficient strength.

されてステアリングホイール用芯材は完成する。 The coupling aid 5 formed in this way is fixed to the back side of each tip of the spoke core material 3 with a rivet 6, and furthermore, the ring fitting insertion portion 5b at the tip is attached to the ring together with the tip of the spoke core material 3. It is inserted into the bottomed groove 2 of the part core metal 1, and in this state, the joint parts of the ring part core metal 1 and the joining aid 2, which are made of the same metal, are welded to complete the steering wheel core material.

合補助具５の先端もリング部芯金１の有底溝部２
に嵌挿されているため、それほど結合補助具５を
大形にしなくても、リング部とスポーク部の結合
部に必要充分な強度をもたせることができる。 The core material for the steering wheel is then set in a molding die, and injection molding of soft synthetic resin such as urethane or vinyl chloride is performed using this core material as an insert to form a coating layer. Since the bottomed groove part 2 of the part core bar 1 is also filled with resin, this serves to prevent the coating layer from rotating, and it is possible to prevent the coating layer of the ring part from peeling off due to twisting. In addition, the tip of the coupling aid 5 as well as the tip of the spoke core material 3 is also connected to the bottomed groove portion 2 of the ring portion core 1.
Since the ring part and the spoke part are fitted into each other, the joining part between the ring part and the spoke part can be provided with necessary and sufficient strength without making the joining aid 5 so large.

る。 The spoke member core material 3 and the coupling aid 5 may be coupled by mechanical means such as caulking in addition to riveting. Furthermore, in the above embodiment, the spoke part core material 3 is made of steel, and the ring part core material and the coupling aid are made of aluminum, but the reverse combination may be used, or various other metals may be used. Furthermore, in addition to metal, ceramics, FRP, synthetic resin with high rigidity, synthetic resin with steel inserts, or a combination of a plurality of materials can also be used for the spoke core material 3.

くても充分な結合強度が得られる。<Effects of the invention> As explained above, according to the steering wheel core material of the present invention, there is no step in the ring part core material compared to a material using a conventional coupling tool, and the diameter of the ring part core material can be reduced. It becomes possible to increase the diameter by that amount, which increases the degree of freedom in design. Further, since the tips of the spoke part core material and the coupling aid are fitted into the bottomed grooves of the ring part core metal, sufficient coupling strength can be obtained without increasing the size of the coupling aid.
さらに、リング部芯金とスポーク部芯材が異種

ができる。 Furthermore, even if the ring core and the spoke core are made of different metals or materials, we can use a joining aid made of the same metal as the ring core to maintain the necessary and sufficient strength between the spoke and ring core. Since we can combine
The degree of freedom in design is increased, and a lightweight, high-strength steering wheel can be manufactured at low cost.
