Description

本考案は、自動車用の車輪を支持するための自動車用ハブに関するものである。  The present invention relates to an automobile hub for supporting automobile wheels.

従来、この種自動車用ハブは、円筒状のハブ本体における外端部外周面に、車輪を支持するための複数の取付孔を有する大径の円盤状フランジ部を一体成形により形成した構成となっている。また、斯かる自動車用ハブの製造方法としては、大型鍛造機を用いて筒状素材を数回のなましと鍛造を行って、円筒状のハブ本体と大径の円盤状フランジ部とを一体成形し、その後、車輪の取付孔部分及び不必要な余肉をプレス又は切削で取り除いて形成するようにしている。  Conventionally, this type of automobile hub has a configuration in which a large-diameter disk-like flange portion having a plurality of mounting holes for supporting a wheel is formed by integral molding on the outer peripheral surface of an outer end portion of a cylindrical hub body. ing. In addition, as a method of manufacturing such a hub for automobiles, a cylindrical material is integrated with a large-diameter disk-shaped flange by annealing and forging a cylindrical material several times using a large forging machine. After forming, the mounting hole portion of the wheel and unnecessary surplus portions are removed by pressing or cutting.

ところが、上記した従来の自動車用ハブでは、車輪の取付孔を有する円盤状フランジ部が大径の円形であるため、ハブ全体としての重さが重くなり、材料も多く必要でコスト高となっていた。  However, in the above-described conventional automobile hub, the disk-like flange portion having the wheel mounting holes is a large-diameter circle, so that the weight of the hub as a whole becomes heavy, a large amount of material is required, and the cost is high. It was.

また、筒状素材から円筒状のハブ本体とハブ外径に対し比較的大径となる円盤状フランジ部とを一体成形するため、鍛造力の高い大型の鍛造機を用いる必要があると共に数回のなましと鍛造を行う必要がある。その結果、その鍛造作業が複雑で手間を要する問題があった。  In addition, it is necessary to use a large forging machine with high forging power and several times to integrally form a cylindrical hub body and a disk-shaped flange portion having a relatively large diameter with respect to the hub outer diameter from a cylindrical material. It is necessary to perform annealing and forging. As a result, there is a problem that the forging operation is complicated and time-consuming.

そこで、本考案は、軽量化が行え、しかも、材料を少なくして低コストで簡単容易に製造できる自動車用ハブの提供を課題とする。  Therefore, an object of the present invention is to provide an automobile hub that can be reduced in weight and can be easily and easily manufactured at low cost with less material.

上記問題を解決するため本考案は、円筒状のハブ本体と、車輪の取付孔を有する支持体とからなり、ハブ本体はその一端部に小径の円形フランジ部を一体に備えている一方、支持体は板状でハブ本体の円形フランジ部に宛がって取付可能な環状基部と、環状基部の外周から等間隔をおいて半径方向外方へ放射状に一体に延びかつ先端部に車輪の取付孔を有する複数本の支持杆部とを備え、支持体の環状基部をハブ本体のフランジ部外面に一体的に固定したことを特徴とする。  In order to solve the above problems, the present invention comprises a cylindrical hub body and a support body having wheel mounting holes, and the hub body is integrally provided with a small-diameter circular flange at one end thereof. The body is plate-shaped and can be attached to the circular flange part of the hub body, and can be attached to the tip of the wheel. And a plurality of support flanges having holes, and the annular base portion of the support body is integrally fixed to the outer surface of the flange portion of the hub body.

本考案の自動車用ハブによれば、一端部に小径の円形フランジ部を一体に備えた円筒状ハブ本体と、板状でハブ本体の円形フランジ部に宛がって取付可能な環状基部と環状基部の外周から等間隔をおいて半径方向外方へ放射状に一体に延びかつ先端部に車輪の取付孔を有する複数本の支持杆部とを備え支持体とから構成し、支持体の環状基部をハブ本体のフランジ部外面に一体的に固定する構造としたから、従来のように円筒状ハブ本体の一端に車輪を支持するための複数の取付孔を有する大径の円盤状フランジ部を一体に備えたものに較べて材料を少なくして軽量化でき、その上、個別にパーツフォーマーなどにより高精度に成形できるので、その製造が簡単容易で量産化でき低コストにできる。  According to the automobile hub of the present invention, a cylindrical hub body integrally provided with a small-diameter circular flange portion at one end portion, and an annular base portion and an annular shape that are plate-shaped and attachable to the circular flange portion of the hub body An annular base portion of the support body, comprising a plurality of support flanges that extend radially outward at equal intervals from the outer periphery of the base portion radially and have a wheel mounting hole at the distal end portion.
