Abstract
【解決手段】アウタ側に車輪が取付けられるフランジ部2を有し、フランジ部2のインナ側に円筒部4が設けられたハブシャフト1と、ハブシャフト1の円筒部4に設けられた複列の軌道11a,11b及びこれらを転動する複数の転動体15a,15bを有する軸受部10とからなり、軸受部10の外輪13の複列の軌道14a,14bの間の外周面を切除して切除部20を設けた。
【選択図】図1
Description
図において、1は例えば鋼材を鍛造により形成したハブシャフトで、アウタ側には複数のボルト固定穴3が設けられて車輪が取付けられるフランジ部2を有し、その中心部のインナ側には後述の軸受部10が設けられる円筒部4が突設されており、円筒部4の中心部には、例えばスプライン(図示せず)が設けられた貫通穴5が設けられている。
そして、駆動軸が回転すると、ハブシャフト1を介して車輪が回転し、その回転力は転走する玉15a,15bを介して、ナックル等に固定された外輪13に支持される。
また、アウタ側の内輪軌道11aをハブシャフト1の円筒部4の外周に、インナ側の内輪軌道11aを円筒部4に装着された内輪12に設けた場合を示したが、両内輪軌道11a,11bをハブシャフト1の円筒部4の外周に設けてもよく、あるいは、外輪と対向して設けられ、円筒部4に圧入される複列の軌道を有する内輪に設けてもよい。
また、切除部20の最深部を円弧状(R形状)に形成したので、この部分への応力集中を緩和することができる。
Claims (2)
- アウタ側に車輪が取付けられるフランジ部を有し、該フランジ部のインナ側に円筒部が設けられたハブシャフトと、前記ハブシャフトの円筒部に設けられた複列の軌道及びこれらを転動する複数の転動体を有する軸受部とからなり、
前記軸受部の外輪の前記複列の軌道の間の外周面を切除して切除部を設けたことを特徴とする車軸用軸受装置。 - 前記切除部は、インナ側が最深でかつ円弧状に形成され、アウタ側に向って徐々に浅くなることを特徴とする請求項1記載の車軸用軸受装置。
