Assembly comprising an articulation spindle supported by a clevis and immobilized in translation by a blocking device integrating a double anti-rotation system
First Claim
1. An assembly comprising:
- an articulation spindle mounted in a first sleeve inserted into a first arm of a clevis and in a second sleeve inserted into a second arm of said clevis, said first sleeve comprising an inner shoulder which projects into said first sleeve and which acts as a stop for a first end of said articulation spindle,a blocking device acting as a stop for a second end of said articulation spindle, the blocking device comprising;
a nut screwed onto a threaded portion of an extension of the second sleeve and comprising an inner shoulder acting as a stop for the second end of the articulation spindle,a locking washer able to adopt a locked state to prevent the nut from rotating with respect to the extension and an unlocked state to allow the nut to be unscrewed,a longilinear element able to adopt a locked state in which the longilinear element passes through at least the nut and the articulation spindle so as to prevent the nut from rotating with respect to the articulation spindle and an unlocked state in which the longilinear element allows the nut to be unscrewed from the threaded portion of the extension, and,wherein the articulation spindle further comprises at least one through hole for receiving the longilinear element.

Abstract
An assembly with an articulation spindle mounted in a first sleeve inserted into a first arm of a clevis and in a second sleeve inserted into a second arm of said clevis. The assembly comprises a blocking device. The blocking device comprises a nut screwed onto a threaded portion of an extension of the second sleeve and comprising an inner shoulder against which the second end of the articulation spindle can come to bear, a locking washer able to adopt a locked state in which it prevents the nut from rotating with respect to the extension and an unlocked state in which it allows the nut to be unscrewed, and a longilinear element able to adopt a locked state in which it passes through at least the nut so as to prevent it from rotating.

7. An assembly comprising:
-
an articulation spindle mounted in a first sleeve inserted into a first arm of a clevis and in a second sleeve inserted into a second arm of said clevis, said first sleeve comprising an inner shoulder which projects into said first sleeve and which acts as a stop for a first end of said articulation spindle, a blocking device acting as a stop for a second end of said articulation spindle, the blocking device comprising; a nut screwed onto a threaded portion of an extension of the second sleeve and comprising an inner shoulder acting as a stop for the second end of the articulation spindle, a locking washer able to adopt a locked state to prevent the nut from rotating with respect to the extension and an unlocked state to allow the nut to be unscrewed, a longilinear element able to adopt a locked state in which the longilinear element passes through at least the nut and the articulation spindle so as to prevent the nut from rotating with respect to the articulation spindle and an unlocked state in which the longilinear element allows the nut to be unscrewed from the threaded portion of the extension, and, wherein the locking washer comprises an orifice having a shape which is complementary with that of the extension of the second sleeve so as to allow the locking washer to move in translation on the extension and to prevent the locking washer from rotating with respect to the extension in the locked state of the locking washer, and, wherein the extension comprises an outer surface with at least one longitudinal channel and wherein the locking washer comprises at least one spur configured to be housed in a longitudinal channel of the extension. - View Dependent Claims (8, 9, 10)

11. An assembly comprising:
-
an articulation spindle mounted in a first sleeve inserted into a first arm of a clevis and in a second sleeve inserted into a second arm of said clevis, said first sleeve comprising an inner shoulder which projects into said first sleeve and which acts as a stop for a first end of said articulation spindle, a blocking device acting as a stop for a second end of said articulation spindle, the blocking device comprising; a nut screwed onto a threaded portion of an extension of the second sleeve and comprising an inner shoulder acting as a stop for the second end of the articulation spindle, a locking washer able to adopt a locked state to prevent the nut from rotating with respect to the extension and an unlocked state to allow the nut to be unscrewed, a longilinear element able to adopt a locked state in which the longilinear element passes through at least the nut and the articulation spindle so as to prevent the nut from rotating with respect to the articulation spindle and an unlocked state in which the longilinear element allows the nut to be unscrewed from the threaded portion of the extension, wherein the articulation spindle comprises a central part, a second portion at its second end which is separated from the central part by a shoulder which is able to bear against the inner shoulder of the nut, the articulation spindle further comprising at least one through hole for receiving the longilinear element. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
