MAJOR SECTION ASSEMBLY FOR ISOKINETIC TRANSMISSION JOINT, SIZE SPECIFYING PROCESS FOR MAJOR SECTION ASSEMBLY, AND ISOKINETIC TRANSMISSION JOINT INCLUDING THIS ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To allow a large bend angle and to use a vehicle at a specific bend angle for a long period by providing the center of the spherical bearing face of a hub between the hub center and a shaft end, and setting the inner end wall face between a void and a sealing element to the same spherical diameter as that of the bearing face. ;SOLUTION: The bearing face 39 of a hub 38 has the center located between the hub center R and a shaft end 42 corresponding to the bearing face 39 and a radius (a). The void inner end wall 34 of a major section 33 and the inner end wall 36 of a closing element 35 have a spherical shape with the same diameter as that of the bearing 39 against a bus line and have a nearly rotating shape against a directrix, and they are formed into the contour of the hyperbola having the axis for the axis 10 of the major section 33. The face portion having the hyperbola contour is specified by the sections of first and second hyperbolas specified by dots 44 on the axis 10 or specified by dots corresponding to the position of the hub 38 near the maximum bend point against the bend axis where the axis 40 of the hub 38 orthogonally crosses and matched with the axis of the major section 33 and the axis of an arm, and the intermediate hyperbola is inferred between two sections by interpolation.;COPYRIGHT: (C)1996,JPO
