Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
118 words
A rotary constant velocity universal joint, comprising: an outer joint member and an inner joint member arranged on the interior of said outer joint member; radially extending recesses formed in one of said inner and outer joint members; torque transmitting balls arranged within said radially extending recesses so as to be radially movable therein; grooves formed in the other of said joint members adapted to have said torque transmitting balls engaged therein for effecting torque transmission between said inner and outer joint members; and an annular resilient member arranged in engagement with said balls and structured to apply thereto a radially directed biasing spring force urging said balls within said recesses into torque transmitting engagement with said grooves.
Claim 2
Dependent Claim
118 words
A rotary constant velocity universal joint, comprising: an outer joint member and an inner joint member arranged on the interior of said outer joint member; radially extending recesses formed in one of said inner and outer joint members; torque transmitting balls arranged within said radially extending recesses so as to be radially movable therein; grooves formed in the other of said joint members adapted to have said torque transmitting balls engaged therein for effecting torque transmission between said inner and outer joint members; and an annular resilient member arranged in engagement with said balls and structured to apply thereto a radially directed biasing spring force urging said balls within said recesses into torque transmitting engagement with said grooves.
Claim 3
Dependent Claim
21 words
A universal joint according to claim 1, further comprising an annular hollow space within which said annular resilient member is located.
Claim 4
Dependent Claim
17 words
A universal joint according to claim 2, wherein said recesses are arranged contiguously with said annular space.
Claim 5
Dependent Claim
22 words
A universal joint according to claim 2, wherein said annular space is formed with an axially directed opening on one side thereof.
Claim 6
Dependent Claim

A universal joint according to claim 2, wherein said annular space is axially closed on both sides thereof.
Claim 7
Dependent Claim
35 words
A universal joint according to claim 2, wherein said recesses are formed in said inner joint member and wherein said annular space is arranged to extend circumferentially radially inwardly of said recesses immediately adjacent thereto.
Claim 8
Dependent Claim
35 words
A rotary constant velocity joint according to claim 1, wherein said recesses are arranged in said outer joint member and wherein said resilient member is arranged to form part of a seal for said joint.
Claim 9
Dependent Claim
30 words
A rotary constant velocity joint according to claim 1, wherein said resilient member is arranged radially inwardly of said balls and applies thereto a radially outwardly directed spring biasing force.
Claim 10
Dependent Claim
30 words
A rotary constant velocity joint according to claim 1, wherein said resilient member is arranged radially outwardly of said balls and applies thereto a radially inwardly directed spring biasing force.
