Abstract
A device including a ball, cage housing the ball and a centering lug, wherein the centering lug has a generally annular form with a radially outer annular periphery and a radially inner annular periphery, the outer annular periphery is integral with the cage and the inner annular periphery is inserted in a groove in the outer periphery of the ball, and the centering lug is elastic and arranged to hold the ball along a predefined axis in a rest position.
Claims8
A pivot linking device comprising:
- an at least partially spherical ball and a cage with an inner housing containing the ball, and
- a centering lug having a generally annular form comprising a radially outer annular periphery and a radially inner annular periphery, wherein the outer annular periphery is fixed within the cage and the inner annular periphery is in a groove in the periphery of the ball, wherein said centering lug is elastic and arranged so as to hold the ball along a predefined axis in a rest position.
A pivot linking device comprising:
- an at least partially spherical ball and a cage with an inner housing containing the ball, and
- a centering lug having a generally annular form comprising a radially outer annular periphery and a radially inner annular periphery, wherein the outer annular periphery is held in a fixed position within the cage and the inner annular periphery is in a groove in the periphery of the ball, wherein said centering lug is elastic and arranged so as to hold the ball along a predefined axis in a rest position,
- wherein the inner annular periphery has an open toric form in cross section, the radius of said toric form being adapted to conform to a rounded form of a base of the groove.
A pivot linking device comprising:
- an at least partially spherical ball and a cage with an inner housing containing the ball, and
- a centering lug having a generally annular form comprising a radially outer annular periphery and a radially inner annular periphery, wherein the outer annular periphery is held in a fixed position within the cage and the inner annular periphery is in a groove in the periphery of the ball, wherein said centering lug is elastic and arranged so as to hold the ball along a predefined axis in a rest position,
- wherein shoulders at axial ends of the ball are configured to rest on the cage while the ball is inclined in relation to the cage at a tilt angle equal to a predefined limit angle.
A pivot linking device comprising:
- a ball having a curved outer surface and a groove in the outer surface extending around the perimeter of the outer surface;
- a cage including an inner surface in sliding engagement with outer surface of the ball, wherein the ball is held within the cage, and
- an annular centering lug having including a radially outer portion fixed within the cage and a radially inner portion extending into the groove of the ball, wherein the radially outer and inner portions are integral and elastic and configured to bias the ball towards a predefined axis.
