Abstract

The steering column consists of a shaft section (2), which has, fitted at one end (3), a yoke (4) of a universal joint. A sleeve (5) is fixed to the yoke, which surrounds the end of the shaft and is joined to it by a plug (6) in a material to filter out vibrations. The sleeve contains cutouts (7-12) into which the material of the plug can penetrate to ensure a good connection of the yoke to the shaft.

La fixation du tampon sur ces pièces est assurée par exemple par adhérisation. On conçoit cependant qu'une telle adhérisation est une opération complexe, coûteuse et délicate à mettre en oeuvre et peut se traduire par des  The attachment of the buffer on these parts is ensured for example by adhesion. It is understood, however, that such adhesion is a complex, costly and delicate operation to implement and can result in

C'est ainsi par exemple que ce matériau peut être du caoutchouc ou autres. La face interne de ce tampon est donc associée à la face externe du tronçon d'arbre 2, tandis que la face externe de ce tampon est associée à la face  For example, this material can be rubber or the like. The internal face of this buffer is therefore associated with the external face of the shaft section 2, while the external face of this buffer is associated with the face

Selon l'invention, le manchon 5 de la fourche de cardan 4 comporte au moins une partie en creux formée sur sa face interne et dans laquelle pénètre du  According to the invention, the sleeve 5 of the gimbal fork 4 comprises at least one hollow part formed on its internal face and into which penetrates the

On conçoit alors que lors de la réalisation du tampon en matériau de filtrage de vibrations, par exemple par moulage, du matériau pénètre dans ces évidements, ce qui permet de sécuriser la liaison entre la fourche de cardan et le  It can therefore be seen that when the pad is made of vibration filtering material, for example by molding, material enters these recesses, which makes it possible to secure the connection between the gimbal fork and the
