Abstract
Abstract A torque transmission device for telescoping drive or propeller shafts. The device comprises a slide relatively slidably mounted within a torque transmission tube and a resilient bellows connected between the slide and a sleeve fixed to an end of the torque transmission tube such that the bellows is in sliding contact with the slide and/or the tube for its stabilization. A first slide ring is mounted on the sleeve for sliding contact with the slide. A second slide ring is also mounted on the sleeve in sliding contact with the slide or at the end of the slide in sliding contact with the interior wall of the torque transmission tube in which case the bellows is enclosed entirely within the tube between the latter and the slide.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
57 words
A torque transmission device for telescoping shafts comprising two parts relatively axially slidably mounted in each other for transmitting torque, resilient bellows means having regular pleats connected between the parts for transmitting torque therebetween, and a sliding, guiding and centering system co-operating with said bellows means for stabilization, said bellows means protecting the guiding and centering system.
Claim 2
Dependent Claim
57 words
A torque transmission device for telescoping shafts comprising two parts relatively axially slidably mounted in each other for transmitting torque, resilient bellows means having regular pleats connected between the parts for transmitting torque therebetween, and a sliding, guiding and centering system co-operating with said bellows means for stabilization, said bellows means protecting the guiding and centering system.
Claim 3
Dependent Claim
45 words
A torque transmission device according to claim 1, wherein one of said parts comprises an axially elognated slide fixed to a shaft or a forked end of a universal joint, and wherein the other of said parts comprises a torque transmission tube enclosing the slide
Claim 4
Dependent Claim
51 words
A torque transmission device according to claim 2, wherein a sleeve is mounted on one end of the torque transmission tube and carries a first slide ring in axial sliding contact with said slide, and wherein the bellows means is effectively connected between the slide and the sleeve on said tube.
Claim 5
Dependent Claim
27 words
A torque transmission device according to claim 3,wherein a second slide ring is carried by the slide in sliding contact with the interior wall of said tube.
Claim 6
Dependent Claim
24 words
A torque transmission device according to claim 3,wherein a second slide ring is also carried by the sleeve in sliding contact with the slide.
Claim 7
Dependent Claim
24 words
A torque transmission device according to claim 3,wherein the sleeve is in sliding contact with a portion of the slide situated within said tube.
Claim 8
Dependent Claim
25 words
A torque transmission device according to claim 3,wherein the sleeve is in sliding contact with a portion of the slide situated within the bellows means.
Claim 9
Dependent Claim
70 words
A torque transmission device according to claim 3,wherein a second slide ring is mounted on the slide in sliding contact with the interior wall of said tube, said bellows means being connected between the sleeve and the end of the slide carrying the second slide ring such that the entire bellows means is enclosed within the torque transmission tube to protect said bellows means from the elements and foreign bodies.
Claim 10
Dependent Claim
23 words
A torque transmission device according to claim 1 wherein said guiding and centering system cooperates with said slide substantially throughout the length thereof.
