Abstract
Abstract Constant velocity joint includes an inner joint member axially displaceable with respect to a surrounding outer joint member, the outer joint member having an inner surface formed with grooves and the inner joint member having an outer surface formed with grooves, a plurality of balls respectively disposed within corresponding grooves of the inner and outer joint members for transmitting torque therebetween, cage means located between the inner and outer joint members and adapted to retain the plurality of balls in a common plane, the outer surface of the inner joint member at one axial end thereof having a spherical surface portion and at the other axial end thereof having a frustoconical surface portion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
113 words
Constant velocity joint comprising an inner joint member axially displaceable with respect to a surrounding outer joint member, said outer joint member having an inner surface formed with grooves and said inner joint member having an outer surface formed with grooves, a plurality of balls respectively disposed within corresponding grooves of said inner and outer joint members for transmitting torque therebetween, cage means located between said inner and outer joint members and adapted to retain said plurality of balls in a common plane, said outer surface of said inner joint member at one axial end thereof having a spherical surface portion and at the other axial end thereof having a frustoconical surface portion.
Claim 2
Dependent Claim
113 words
Constant velocity joint comprising an inner joint member axially displaceable with respect to a surrounding outer joint member, said outer joint member having an inner surface formed with grooves and said inner joint member having an outer surface formed with grooves, a plurality of balls respectively disposed within corresponding grooves of said inner and outer joint members for transmitting torque therebetween, cage means located between said inner and outer joint members and adapted to retain said plurality of balls in a common plane, said outer surface of said inner joint member at one axial end thereof having a spherical surface portion and at the other axial end thereof having a frustoconical surface portion.
Claim 3
Dependent Claim
46 words
Joint according to claim 1, wherein said grooves formed in said inner and outer joint members are disposed in respective pairs opposite one another, the grooves of each pair being respective longitudinal center lines intersecting one another in said common plane wherein said balls are retained.
Claim 4
Dependent Claim
25 words
Joint according to claim 1, wherein said inner surface of said outer joint member is cylindrical, and said cage means has a spherical outer surface.
Claim 5
Dependent Claim
24 words
Joint according to claim 1, wherein said cage means has an inner surface at said one axial end formed with a spherical surface portion.
Claim 6
Dependent Claim
24 words
Joint according to claim 4, wherein said cage means has an inner surface at said other axial end formed with a frustoconical surface portion.
Claim 7
Dependent Claim
33 words
Joint according to claim 5, wherein said frustoconical surface portion of said cage means has a sharper cone angle than the cone angle of said frustoconical surface portion of said inner joint member.
Claim 8
Dependent Claim
25 words
Joint according to claim 4, wherein said cage means has an inner surface at said other axial end formed with a substantially cylindrical surface portion.
Claim 9
Dependent Claim
33 words
Joint according to claim 1, wherein said cage means has an inner surface spaced from said inner joint member so as to afford axial displacement thereof with respecT to said inner joint member.
Claim 10
Dependent Claim
59 words
Joint according to claim 1, wherein said cage means is displaceable in all axial positions of said inner joint member through a given angle determined by a relationship between an angle of deflection of the joint and a relative displacement distance between said inner and outer joint members, before abutting against the outer surface of said inner joint member.
Claim 11
Dependent Claim
53 words
A Cardan shaft including two of the constant velocity joints according to claim 1, the two joints being located at opposite ends of an intermediate shaft, the respective spherical surface portions on said inner joint members and said cage means of the two joints being located at opposite ends of the respective joints.
