Abstract
Abstract A gripping roller free-wheeling device, with a springy support of the gripping rollers on cross tongues of a cage which is formed by two or more annular members disposed adjacent the gripping rollers; the tongues are stamped out of the sheet metal annular members and are bent off approximately at right angle to the plane of the annular members whereby the form and position of the stamping edge is such that the stamped-out openings which remain in one annular member approximately within the area of half the pitch of the cross tongues, permit the passage therethrough of the bent-off cross tongues of the other annular member.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
108 words
A gripping roller free-wheeling device comprising an elastic support of gripping rollers on cross tongues of a cage means, said cage means being formed by a ring means disposed adjacent the gripping rollers, the tongues being stamped out of the ring means and being bent along a bending edge approximately at right angle to the plane of the ring means, characterized in that at least two ring means are used which are offset to one another in such a manner that the tongues of one ring means are able to pass through the openings remaining in the other ring means after completion of the stamping and bending-out operations.
Claim 2
Dependent Claim
108 words
A gripping roller free-wheeling device comprising an elastic support of gripping rollers on cross tongues of a cage means, said cage means being formed by a ring means disposed adjacent the gripping rollers, the tongues being stamped out of the ring means and being bent along a bending edge approximately at right angle to the plane of the ring means, characterized in that at least two ring means are used which are offset to one another in such a manner that the tongues of one ring means are able to pass through the openings remaining in the other ring means after completion of the stamping and bending-out operations.
Claim 3
Dependent Claim
57 words
A gripping roller free-wheeling device according to claim 1, characterized by such a configuration and location of the stamping edges that the bent-off cross tongues of the one ring means are able to pass through the stamped-out openings of the other ring means approximately within the area of one half the pitch of the cross tongues thereof.
Claim 4
Dependent Claim
27 words
A gripping roller free-wheeling device according to claim 2, characterized in that the ring means forming the cage means are each constituted by a sheet metal ring.
Claim 5
Dependent Claim
25 words
A gripping roller free-wheeling device according to claim 2, characterized in that the free-wheeling device is for the guide wheel of a hydrodynamic torque converter.
Claim 6
Dependent Claim
24 words
A gripping roller free-wheeling device according to claim 2, characterized in that the free-wheeling device is for parts of a planetary gear change-speed transmission.
Claim 7
Dependent Claim
46 words
A gripping roller free-wheeling device according to claim 1, characterized in that each of the two ring means have stamped-out and bent-off cross tongues which are displaced with respect to one another by about half the pitch of the cross tongues in a respective ring means.
Claim 8
Dependent Claim
43 words
A gripping roller free-wheeling device with an outer race according to claim 6, characterized in that at least one of the cross tongues is provided with a radially outwardly directed nose portion for engagement in a corresponding groove provided in the outer race.
Claim 9
Dependent Claim
46 words
A gripping roller free-wheeling device according to claim 7, characterized in that the upper edge of the stamped-out edges of the cross tongues is slightly inclined with respect to a tangent at the bending edge which extends substantially in the radial direction of the ring means.
Claim 10
Dependent Claim
53 words
A gripping roller free-wheeling device according to claim 8, characterized in that the inclination of the upper edge is so selected that the upper edge within the area of about half the pitch, lies radially outwardly of the circle which passes through the uppermost portion of the bending edge of a respective tongue.
Claim 11
Dependent Claim
64 words
A gripping roller free-wheeling device according to claim 9, characterized in that in connection with the cross tongue having the nose portion, the upper edge of the nose portion is disposed radially outwardly of the circular arc which extends through the point obtained by the projection of the upper edge on the bending edge, with the bending edge extending substantially in the radial direction.
Claim 12
Dependent Claim
27 words
A gripping roller free-wheeling device according to claim 10, characterized in that the ring means forming the cage means are each constituted by a sheet metal ring.
Claim 13
Dependent Claim
43 words
A gripping roller free-wheeling device with an outer race according to claim 1, characterized in that at least one of the cross tongues is provided with a radially outwardly directed nose portion for engagement in a corresponding groove provided in the outer race.
Claim 14
Dependent Claim
46 words
A gripping roller free-wheeling device according to claim 1, characterized in that the upper edge of the stamped-out edges of the cross tongues is slightly inclined with respect to a tangent at the bending edge which extends substantially in the radial direction of the ring means.
Claim 15
Dependent Claim
53 words
A gripping roller free-wheeling device according to claim 13, characterized in that the inclination of the upper edge is so selected that the upper edge within the area of about half the pitch, lies radially outwardly of the circle which passes through the uppermost portion of the bending edge of a respective tongue.
Claim 16
Dependent Claim
43 words
A gripping roller free-wheeling device with an outer race according to claim 13, characterized in that at least one of the cross tongues is provided with a radially outwardly directed nose portion for engagement in a corresponding groove provided in the outer race.
Claim 17
Dependent Claim
64 words
A gripping roller free-wheeling device according to claim 15, characterized in that in connection with the cross tongue having the nose portion, the upper edge of the nose portion is disposed radially outwardly of the circular arc which extends through the point obtained by the projection of the upper edge on the bending edge, with the bending edge extending substantially in the radial direction.
