Abstract

Abstract The invention relates to improved free-wheel mechanisms adapted to couple together or to disconnect two members capable of relative rotation. The free-wheel mechanism is intended to cooperate with inner and outer circular tracks, one of said tracks having ramp means and the other of said tracks having a plain surface, comprising a plurality of jamming members and a cage therefor, said cage comprising two parts, a first part having a plurality of circumferentially spaced windows for receiving the jamming members, and a second part having a plurality of depressions received in said windows and portions folded over said first part for limiting at least relative radial movement of said parts, the bottom end of at least one of said depressions providing a friction surface for cooperation with said plain track surface. The free-wheel mechanisms find advantageous applications in vehicle transmission systems, for example in hydraulic torque converters.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 111 words
A free wheel mechanism adapted to cooperate with inner and outer circular tracks, one of said tracks having ramp means and the other of said tracks having a plain surface, comprising a plurality of jamming members and a cage therefor, said cage comprising two parts, a first part having a plurality of circumferentially spaced windows for receiving the jamming members, and a second part having a plurality of depressions received in said windows and portions folded over said first part for limiting at least relative radial movement of said parts, the bottom end of at least one of said depressions providing a friction surface for cooperation with said plain track surface.
Claim 2
Dependent Claim 111 words
A free wheel mechanism adapted to cooperate with inner and outer circular tracks, one of said tracks having ramp means and the other of said tracks having a plain surface, comprising a plurality of jamming members and a cage therefor, said cage comprising two parts, a first part having a plurality of circumferentially spaced windows for receiving the jamming members, and a second part having a plurality of depressions received in said windows and portions folded over said first part for limiting at least relative radial movement of said parts, the bottom end of at least one of said depressions providing a friction surface for cooperation with said plain track surface.
Claim 3
Dependent Claim 25 words
A free wheel mechanism according to claim 1, wherein the curvature of said friction surface is complementary to the curvature of said plain track surface.
Claim 4
Dependent Claim 31 words
A free wheel mechanism as claimed in claim 2, wherein said inner track has said plain track surface and said outer track has said ramp means, the jamming members being cylinders.
Claim 5
Dependent Claim 40 words
A free wheel mechanism according to claim 1, wherein the second part includes a plurality of elevated portions alternating with said depression, said elevated portions and depression being arcuate, and radially disposed portions connecting the elevated portions with the depression.
Claim 6
Dependent Claim 28 words
A free wheel mechanism according to claim 4, wherein windows are provided in both the elevated portions and the depression for the passage of the jamming members therethrough.
Claim 7
Dependent Claim 43 words
A free wheel mechanism according to claim 1, wherein the bottom ends of all the depressions provide friction surfaces of rectangular shape in plan, the central zone of the said friction surfaces being concave facing the plain track surface with which they cooperate.
