Abstract
Abstract A constant velocity joint with torque transmission by means of balls cooperating with grooves in meridian planes in inner and outer joint members with the balls guided in windows of a cage having spherical inside and outside surfaces. The groove surfaces are not undercut in the longitudinal direction and are made up of at least two axially adjoining lines, either curved or straight, when viewed in longitudinal section.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
66 words
A constant velocity joint for torque transmission comprising an inner joint member and an outer joint member having grooves therein arranged in pairs in meridian planes and with said grooves having surfaces extending without undercutting in the longitudinal direction and forming a jaw-shaped opening in the longitudinal direction, surfaces on said inner and outer joint members, and having windows in said cage for guiding said balls.
Claim 2
Dependent Claim
66 words
A constant velocity joint for torque transmission comprising an inner joint member and an outer joint member having grooves therein arranged in pairs in meridian planes and with said grooves having surfaces extending without undercutting in the longitudinal direction and forming a jaw-shaped opening in the longitudinal direction, surfaces on said inner and outer joint members, and having windows in said cage for guiding said balls.
Claim 3
Dependent Claim
20 words
The constant velocity joint according to claim 1, further characterized by said adjoining lines being lines of the same order.
Claim 4
Dependent Claim
28 words
The constant velocity joint according to claim 2, further characterized by said adjoining lines being to straight lines having different inclinations to the longitudinal axis of the joint.
Claim 5
Dependent Claim
28 words
The constant velocity joint according to claim 3, further characterized by one of said two straight lines extending in parallel relationship to the longitudinal axis of the joint.
Claim 6
Dependent Claim
18 words
The constant velocity joint according to claim 2, further characterized by said adjoining lines being three straight lines.
Claim 7
Dependent Claim
22 words
The constant velocity joint according to claim 1, further characterized by said adjoining lines being an arcuate portion and a straight line.
Claim 8
Dependent Claim
148 words
A constant velocity for torque transmission comprising an inner joint member and an outer joint member having grooves therein arranged in pairs in meridian planes and with said grooves extending in the form of arcs of a circle in the longitudinal direction and having centres of curvature offset in pairs by equal distances to opposite sides of the joint centre with the centres of curvature situated on a parallel to the axis of the joint and the distances of the centres of curvature from a centre plane transversely through the joint being at least equal to the distance of the end face of said outer joint member from the joint centre plane balls cooperating with said grooves, and a cage having spherical outside and inside surfaces cooperating with complementary groove surfaces on said inner and outer joint members, and having windows in said cage for guiding said balls.
Claim 9
Dependent Claim
