Abstract
Abstract A universal joint assembly which includes a first and a second yoke operatively interconnected by a trunnion cross arranged therebetween is formed with a generally centrally located bore extending through the trunnion cross between the first and the second yoke with a bolt extending within the bore interconnecting the first and second yoke through the trunnion cross. One end of the bolt is attached to a radially movable member in the first yoke and lock means are provided for locking the radially movable element in any selected position in order to fix the position of a connecting member joined to the second yoke so that interconnection of torque transmitting elements may be facilitated.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
A universal joint assembly comprising: first and second yoke means; trunnion cross means operatively connected between said first and second yoke means for torque transmission therebetween; means defining a generally centralized bore extending through said trunnion cross means between said first and second yoke means; bolt means extending within said bore connected between said first and second yoke means through said trunnion cross means; radially movable means in said first yoke means having said bolt means angularly movably received therein; and locking means for locking said radially movable means in any selected position thereof.
Claim 2
Dependent Claim
94 words
A universal joint assembly comprising: first and second yoke means; trunnion cross means operatively connected between said first and second yoke means for torque transmission therebetween; means defining a generally centralized bore extending through said trunnion cross means between said first and second yoke means; bolt means extending within said bore connected between said first and second yoke means through said trunnion cross means; radially movable means in said first yoke means having said bolt means angularly movably received therein; and locking means for locking said radially movable means in any selected position thereof.
Claim 3
Dependent Claim
45 words
A universal joint assembly according to claim 1 wherein in the region between said trunnion cross means and said first yoke means, said bolt is rigidly connected to said second yoke means by a member which connects the yoke arms of said second yoke means.
Claim 4
Dependent Claim
39 words
A universal joint assembly according to claim 1 wherein said locking means comprise a pressure member which is guided in an axially extending bore, said pressure member being operated as one of a hydraulically, pneumatically or mechanically actuated device.
Claim 5
Dependent Claim
45 words
A universal joint assembly according to claim 3 wherein said radially movable means comprise a radially movable member and an intermediate piece formed of material having a high coefficient of friction, said intermediate piece being arranged between said pressure member and said radially movable member.
Claim 6
Dependent Claim
28 words
A universal joint assembly according to claim 3 wherein said locking means comprise a spherical element operatively interposed to cooperate between said bolt means and said locking means.
Claim 7
Dependent Claim
131 words
A universal joint assembly according to claim 1 wherein a pair of universal joints are connected by an intermediate shaft, each of said pair of universal joints including said first and said second yoke means and said trunnion cross means, each of said pair of universal joints including said bolt means arranged in operative connection with said first yoke means of each of said universal joints, said assembly further comprising an internal shaft extending from the first yoke means of one of said pair of universal joints to the first yoke means of the other of said pair of universal joints, said internal shaft extending in the interior of an intermediate shaft extending between said pair of universal joints supported to be angularly movable with equal spacing from both universal joints.
Claim 8
Dependent Claim
25 words
A universal joint assembly according to claim 6 wherein said internal shaft comprises intermediate bearing means having unequal spacing from said pair of universal joints.
