In this type of wheel support device, as shown in FIG. 3, the inner ring 121 of the rolling bearing 120 is fitted and inserted into the outer peripheral surface of the hub shaft 113 of the hub wheel 110, and the shaft end portion that forms the cylindrical shaft shape of the hub shaft 113 is formed. There is a structure in which the inner ring 121 is fixed to the outer peripheral surface of the hub shaft 113 by caulking toward the end surface (radially outward) of the inner ring 121 and forming a caulking portion 117.
Further, in order to connect the hub wheel 110 and the constant velocity joint 150 so that torque can be transmitted, the end surface of the caulking portion 117 of the hub shaft 113 and the side wall of the outer ring 160 of the constant velocity joint 150 that abuts against the end surface of the caulking portion 117.

ところで、ハブホイール110のハブ軸113の外周面に転がり軸受120の内輪121がかしめ部117によって組み付けられた後、かしめ部117の端面に、サイドフェーススプライン126を鍛造加工によって同軸度を確保して形成することは困難な作業となる。
また、サイドフェーススプライン126を鍛造加工によって形成する際、内輪121に軸方向の圧縮力が作用し、これによって、内輪121の軌道面122に悪影響を及ぼす懸念がある。
さらに、ハブ軸113のかしめ部117に形成されたサイドフェーススプライン126の品質保証検査においても、ハブ軸113に内輪121を含む転がり軸受120が組み付けられた状態で行わなければならず厄介であった。
By the way, after the inner ring 121 of the rolling bearing 120 is assembled to the outer peripheral surface of the hub shaft 113 of the hub wheel 110 by the caulking portion 117, the side face spline 126 is secured to the end surface of the caulking portion 117 by forging. Forming is a difficult task.
Further, when the side face spline 126 is formed by forging, there is a concern that an axial compressive force acts on the inner ring 121, thereby adversely affecting the raceway surface 122 of the inner ring 121.
Further, the quality assurance inspection of the side face spline 126 formed on the caulking portion 117 of the hub shaft 113 is also troublesome because the rolling bearing 120 including the inner ring 121 is assembled to the hub shaft 113. .

この発明の目的は、前記問題点に鑑み、ハブホイールのハブ軸の端部のかしめ部を廃止して、ハブ軸と、等速ジョイントの外輪とを良好にトルク伝達することができ、軽量化やコスト低減においても効果が大きい車輪支持装置を提供することである。   In view of the above-described problems, the object of the present invention is to eliminate the caulking portion at the end of the hub shaft of the hub wheel, and to transmit torque favorably between the hub shaft and the outer ring of the constant velocity joint. Another object of the present invention is to provide a wheel support device that is highly effective in reducing costs.

前記目的を達成するために、この発明の請求項1に係る車輪支持装置は、車輪が取り付けられるハブホイールのハブ軸の外周面に転がり軸受が設けられ、前記ハブ軸と、等速ジョイントの外輪とがトルク伝達可能に連結された車輪支持装置であって、
前記転がり軸受の内輪の端面と、この端面に突き合わされる前記等速ジョイントの外輪の側壁部の端面には、相互に噛み合う両サイドフェーススプラインが形成され、
前記ハブ軸の外周面と前記転がり軸受の内輪の内周面には、相互に噛み合う外歯スプラインと内歯スプラインとがそれぞれ形成されていることを特徴とする。
In order to achieve the above object, a wheel support device according to claim 1 of the present invention is provided with a rolling bearing on an outer peripheral surface of a hub shaft of a hub wheel to which a wheel is attached, and the outer shaft of the hub shaft and a constant velocity joint. Is a wheel support device coupled to transmit torque,
Both side face splines that mesh with each other are formed on the end face of the inner ring of the rolling bearing and the end face of the side wall portion of the outer ring of the constant velocity joint that is abutted against the end face.
The outer peripheral surface of the hub shaft and the inner peripheral surface of the inner ring of the rolling bearing are respectively formed with external tooth splines and internal tooth splines that mesh with each other.

前記構成によると、等速ジョイント側のトルクは、同等速ジョイントの外輪のサイドフェーススプラインと、ハブホイール側の転がり軸受の内輪のサイドフェーススプラインとの噛み合いによって転がり軸受の内輪に伝達され、この内輪の内歯スプラインとハブホイールのハブ軸の外周面の外歯スプラインとの噛み合いによってハブ軸に伝達される。
このようにして、ハブホイール側の転がり軸受の内輪の端面にサイドフェーススプラインを、同内輪の内周面に内歯スプラインを形成することによって、ハブホイールのハブ軸端部のかしめ部を廃止して、ハブ軸と、等速ジョイントの外輪とを良好にトルク伝達することができる。
また、ハブ軸の端部のかしめ部を廃止した分だけ車輪支持装置の軸長を短縮化することができ、これによって軽量化を図ることができる。
さらに、ハブホイール側の転がり軸受を構成する単品状態の内輪の端面にサイドフェーススプラインを、内周面に内歯スプラインを鍛造等によって容易に形成することができる。さらに、各スプラインを形成した後、内輪の単品の状態で品質保証検査を容易に行うことができ、コスト低減においても有効である。
According to the above configuration, the torque on the constant velocity joint side is transmitted to the inner ring of the rolling bearing by meshing with the side face spline of the outer ring of the equivalent speed joint and the side face spline of the inner ring of the rolling bearing on the hub wheel side. Is transmitted to the hub shaft by meshing with the external splines of the outer peripheral surface of the hub shaft of the hub wheel.
In this way, the side face spline is formed on the end surface of the inner ring of the rolling bearing on the hub wheel side, and the inner spline is formed on the inner peripheral surface of the inner ring, thereby eliminating the caulked portion of the hub wheel end of the hub wheel. Thus, torque can be satisfactorily transmitted between the hub shaft and the outer ring of the constant velocity joint.
Further, the shaft length of the wheel support device can be shortened by the amount corresponding to the elimination of the caulking portion at the end of the hub shaft, thereby reducing the weight.
Furthermore, a side face spline can be easily formed on the end surface of the single inner ring constituting the hub wheel side rolling bearing, and an internal spline can be easily formed on the inner peripheral surface by forging or the like. Furthermore, after each spline is formed, quality assurance inspection can be easily performed in the state of a single inner ring, which is effective in reducing costs.
