PROBLEM TO BE SOLVED: To provide a cross globe type constant universal joint capable of improving its fixing workability for a vehicle while NVH performance of a vehicle is being kept.SOLUTION: This invention relates to a non-float type cross-globe shaped constant velocity universal joint in which a maximum outer diameter of an inner joint member is set to be smaller than a minimum inner diameter of a cage. This joint has a ball moving range under its practical application. This invention has a relation of δ1<δ2 where δ1 is a clearance at a central part between a ball groove of an outer joint member and a ball groove of the inner joint member within the ball moving range and δ2 is an end part clearance between a ball groove of an outer joint member and a ball groove of the inner joint member out of the moving range. The clearance at the central part constitutes a fastening fitting and the end clearance constitutes fastening fitting or clearance fitting having a smaller fastening margin than that of the fastening margin at the central clearance.SELECTED DRAWING: Figure 3
【課題】車両のNVH性能は維持したままで、車両への取付け作業性の向上を図れるクロスグローブ型等速自在を提供する。【解決手段】ケージの最小内径よりも内側継手部材の最大外径を小さく設定したノンフロートタイプのクロスグローブ型の等速自在継手である。使用状態におけるボールの移動範囲を有し、この移動範囲における外側継手部材のボール溝と内側継手部材のボール溝との間の中央部隙間をδ1とし、移動範囲外における外側継手部材のボール溝と内側継手部材のボール溝との間の端部隙間をδ2としたときに、δ1<δ2とした。中央部隙間がしまりばめを構成し、端部隙間が中央部隙間の締め代よりも小さい締め代のしまりばめ、又はすきまばめを構成する。【選択図】図3
