Abstract
Abstract The present invention relates to a free-wheel constituting a oneway coupling device and comprising a circular series of jamming members adapted to be interposed between an outer track and an inner track coaxial with each other, a plurality of ramps provided on at least one of said tracks, said ramps being adapted to co-operate with said jamming members, a synchronization cage for housing said jamming members, said cage being subjected to an elastic restoring action, and two lateral closure rings, coupling means for directly interconnecting said closure rings so as to fix said rings angularly to said track with ramps, said elastic restoring means acting on said cage being constituted by springs of circular arcuate form, hooked at one extremity on said synchronization cage and at the other extremity on said lateral closure rings. An important application of the invention is to hydrokinetic torque converters.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
A free-wheel forming a one-way coupling device comprising a circular series of jamming members adapted to be interposed between an outer track and an inner track coaxial with each other, a plurality of ramps provided on at least one of said tracks, said ramps being adapted to cooperate with said jamming members, a synchronization cage for housing said jamming members, said cage being subjected to an elastic restoring action, and two lateral closure rings, said free-wheel further comprising coupling means for directly interconnecting said two closure rings, said coupling means comprising at least one straight pin parallel to the axis of said free-wheel and passing through this latter, said pin having its extremities elbowed in such manner as to retain said closure rings axially.
Claim 2
Dependent Claim
124 words
A free-wheel forming a one-way coupling device comprising a circular series of jamming members adapted to be interposed between an outer track and an inner track coaxial with each other, a plurality of ramps provided on at least one of said tracks, said ramps being adapted to cooperate with said jamming members, a synchronization cage for housing said jamming members, said cage being subjected to an elastic restoring action, and two lateral closure rings, said free-wheel further comprising coupling means for directly interconnecting said two closure rings, said coupling means comprising at least one straight pin parallel to the axis of said free-wheel and passing through this latter, said pin having its extremities elbowed in such manner as to retain said closure rings axially.
Claim 3
Dependent Claim
38 words
A free-wheel as claimed in claim 1, in which said pin is engaged in a groove formed in said track with ramps in such manner as to ensure the angular fixing of said rings to said ramp track.
Claim 4
Dependent Claim
27 words
A free-wheel as claimed in claim 1, in which said pin is engaged, in the vicinity of its extremities, in slots provided in said lateral closure rings.
Claim 5
Dependent Claim
47 words
A free-wheel as claimed in claim 1, in which the elbowed extremities of said pin are bent back in such manner that one extremity is engaged in a hole in one ring while the other is engaged on the periphery of the other said lateral closure ring.
Claim 6
Dependent Claim
60 words
A free-wheel as claimed in claim 4, in which said pin is elastic and when at rest has its two turned-back extremities in alignment, whereas in the assembled position in which one of said extremities is engaged on the periphery of the other said ring, said pin is subjected to a stress which locks said pin in said assembled position.
Claim 7
Dependent Claim
16 words
A free-wheel as claimed in claim 1, in which a plurality of said pins is provided.
Claim 8
Dependent Claim
17 words
A free-wheel as claimed in claim 6 in which two said pins are provided in diametrically-opposite positions.
Claim 9
Dependent Claim
146 words
A free-wheel forming a one-way coupling device comprising a circular series of jamming members adapted to be interposed between an outer track and an inner track coaxial with each other, a plurality of ramps provided on at least one of said tracks, said ramps being adapted to cooperate with said jamming members, a synchronization cage for housing said jamming members, means for applying an elastic restoring action to said cage, and two lateral closure rings, said elastic restoring means acting on said cage being constituted by springs of circular arcuate form hooked at one extremity to said synchronization cage and at the other extremity to said two lateral closure rings which are angularly fixed to said track provided with ramps, said springs of circular arcuate form being two in number and having their hooking extremities on said cage and said rings extending away from each other.
Claim 10
Dependent Claim
146 words
A free-wheel forming a one-way coupling device comprising a circular series of jamming members adapted to be interposed between an outer track and an inner track coaxial with each other, a plurality of ramps provided on at least one of said tracks, said ramps being adapted to cooperate with said jamming members, a synchronization cage for housing said jamming members, means for applying an elastic restoring action to said cage, and two lateral closure rings, said elastic restoring means acting on said cage being constituted by springs of circular arcuate form hooked at one extremity to said synchronization cage and at the other extremity to said two lateral closure rings which are angularly fixed to said track provided with ramps, said springs of circular arcuate form being two in number and having their hooking extremities on said cage and said rings extending away from each other.
