Abstract
Abstract The invention consists in that the guide rolls of a cardan shaft drive with two telescopable shaft parts are held with bias in an inset device which presents a trough-shaped depression for each guide roll, and recesses for the back-running roll bodies, said inset device being held in the external shaft part by projections that are in positive engagement therein.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
109 words
A cardan drive shaft with two telescoping shaft parts joined so as to be fixed relative to each other in rotation, by circulating roll bodies with guide tracks for the roll bodies, an inner guide track comprising axially running guide grooves, an intermediate ring of guide rolls applied against each other without clearance, said guide rolls being disposed in the outer shaft part so as to be fixed against twisting, and held with bias in an inset device which presents a troughlike depression for each guide roll and recesses for the back-running roll bodies and which is held in the outer shaft part by projections that positively engage therein.
Claim 2
Dependent Claim
109 words
A cardan drive shaft with two telescoping shaft parts joined so as to be fixed relative to each other in rotation, by circulating roll bodies with guide tracks for the roll bodies, an inner guide track comprising axially running guide grooves, an intermediate ring of guide rolls applied against each other without clearance, said guide rolls being disposed in the outer shaft part so as to be fixed against twisting, and held with bias in an inset device which presents a troughlike depression for each guide roll and recesses for the back-running roll bodies and which is held in the outer shaft part by projections that positively engage therein.
Claim 3
Dependent Claim
24 words
Cardan drive shaft according to claim 1, characterized in that the recesses for the back-running roll bodies are in the form of axial slits.
Claim 4
Dependent Claim
22 words
Cardan drive shaft according to claim 2, characterized in that the axial slits pass through to one face of the inset device.
Claim 5
Dependent Claim
42 words
Cardan drive shaft according to claim 2, characterized in that the inset device is multipartite having a first part in which said slits are formed, and a closure part, at a front face of the first part, into which the slits open.
Claim 6
Dependent Claim
23 words
Cardan drive shaft according to claim 1, characterized in that the depressions for the guide rolls present an axial stop at one end.
Claim 7
Dependent Claim
18 words
Cardan drive shaft according to claim 5, characterized in that the axial stop is made as a collar.
Claim 8
Dependent Claim
19 words
Cardan drive shaft according to claim 1, characterized in that the inset device is made of elastically deformable plastic.
Claim 9
Dependent Claim
17 words
Cardan drive shaft according to claim 1, characterized in that the inset device is made of aluminum.
Claim 10
Dependent Claim
88 words
A cardan drive having inner and outer telescoping shaft parts, connected so as to be jointly rotatable, by roll bodies which circulate within a plurality of track means, each said track means having inner and outer paths, said inner path being defined between said inner shaft part and an intermediate ring of guide rolls, said outer path being defined between said guide rolls and said outershaft part, and inset means between said outer part and said guide rolls for biasing said guide rolls against each other without clearance.
Claim 11
Dependent Claim
88 words
A cardan drive having inner and outer telescoping shaft parts, connected so as to be jointly rotatable, by roll bodies which circulate within a plurality of track means, each said track means having inner and outer paths, said inner path being defined between said inner shaft part and an intermediate ring of guide rolls, said outer path being defined between said guide rolls and said outershaft part, and inset means between said outer part and said guide rolls for biasing said guide rolls against each other without clearance.
Claim 12
Dependent Claim
23 words
The cardan drive according to claim 9, wherein said inset means is provided with troughlike depressions within which said guide rolls are received.
Claim 13
Dependent Claim
26 words
The cardan drive according to claim 10, wherein said inset means is formed of elastically deformable material and has slits forming portions of said outer paths.
Claim 14
Dependent Claim
19 words
Cardan drive shaft according to claim 1, characterized in that the inset device is made of a nonferrous metal.
