Abstract

The damper consists of an elastic pad (6) which is pressed down onto the tow-ball (5). A trailer coupling member is composed by a threaded rod (1) and a handwheel (2) on an arm (4) mounted on a bracket (8). The bracket is fitted between the towing ball and vehicle chassis. The arm can be turned to one side to allow the trailer coupling member to be fitted or disengaged. The pad can be compressed by 6-7 mm to absorb movements in the coupling.

Description

DESCRIPTION
La présente invention concerne un dispositif destiné à atténuer la production de claquements au niveau de la sphère des attelages pour remorques de voitures automobiles.DESCRIPTION
The present invention relates to a device intended to attenuate the production of clicks in the sphere of couplings for trailers of motor cars.

Tous les systèmes élaborés jusqu'à présent traitent de l'absorption des chocs et vibrations et solutionnent la protection des pièces mécaniques d'assemblage, mais ne s'attachent pas à réduire les claquements dus aux jeux mécaniques entre la sphère et la tête d'attelage de la remorque. Ces claquements se répercutent à l'intérieur de la voiture, par les différentes liaisons mécaniques, représentant ainsi un élément d'inconfort phonique au roulage. All the systems developed so far deal with the absorption of shock and vibration and solve the protection of the mechanical assembly parts, but do not endeavor to reduce the clicks due to the mechanical games between the sphere and the head. trailer hitch. These clicks reverberate inside the car, through the various mechanical connections, thus representing an element of phonic discomfort when driving.

L'invention permet de supprimer l'effet de résonance ressenti à l'intérieur de la voiture, surtout lorsque la remorque est vide. The invention eliminates the resonance effect felt inside the car, especially when the trailer is empty.

Le dispositif selon l'invention comporte, selon une première caractéristique, un plot élastique tenu en pression sur la tête d'attelage à l'aide d'un écrou moleté se vissant sur une tige filetée fixée sur une équerre d'adaptation. The device according to the invention comprises, according to a first characteristic, an elastic stud held under pressure on the coupling head by means of a knurled nut screwing onto a threaded rod fixed to an adaptation bracket.

Les dessins annexés illustrent l'invention:
La figure 1 représente en coupe, le dispositif selon l'invention, avec la tête d'attelage
La figure 2 représente en vue de dessus le dispositif selon l'invention, sans la tête d'attelage.The accompanying drawings illustrate the invention:
Figure 1 shows in section, the device according to the invention, with the coupling head
2 shows a top view of the device according to the invention, without the coupling head.

La figure 3 représente un détail en coupe. Figure 3 shows a detail in section.

En référence à ces dessins, le dispositif comporte un axe principal (1), constitué par une tige filetée fixée sur l'équerre d'adaptation (8). With reference to these drawings, the device comprises a main axis (1), constituted by a threaded rod fixed to the adaptation bracket (8).

Un écrou moleté (2) se déplace par vissage sur cette tige filetée afin de faire pression sur un bras articulé (4), libre en rotation et translation. Ce bras (4), sur lequel est monté un plot élastique (6), libre en rotation, peut pivoter pour permettre la mise en place ou le dégagement de la tête d'attelage. Un coussinet de positionnement (3) permet de bloquer le bras (4) afin que l'axe du plot (6) se trouve dans l'axe de la rotule. A knurled nut (2) moves by screwing on this threaded rod in order to put pressure on an articulated arm (4), free in rotation and translation. This arm (4), on which is mounted an elastic stud (6), free to rotate, can pivot to allow the positioning or disengagement of the coupling head. A positioning pad (3) blocks the arm (4) so that the axis of the stud (6) is in the axis of the ball joint.

L'ensemble de ces pièces est ainsi assemblé selon la figure 1 pour obtenir une compression du plot élastique (6) de 6 à 7 mm. Cet écrasement provoquera une force d'appui verticale, de haut en bas, sur la tête d'attelage et l'élasticité du plot (6), permettra d'absorber les différents mouvements de pivotement et de changement de plan de la surface d'appui. All of these parts are thus assembled according to Figure 1 to obtain a compression of the elastic pad (6) from 6 to 7 mm. This crushing will cause a vertical bearing force, from top to bottom, on the coupling head and the elasticity of the stud (6), will absorb the different pivoting movements and change of plane of the surface. support.

A titre d'exemple non limitatif, le dispositif aura des dimensions de l'ordre de 16 cm pour la hauteur, 6 cm pour la largeur et 12 cm pour la profondeur. By way of nonlimiting example, the device will have dimensions of the order of 16 cm for the height, 6 cm for the width and 12 cm for the depth.

Le dispositif selon l'invention est particulièrement destiné à atténuer la production de claquements, au niveau des tetes d'attelage des remorques, au roulage.  The device according to the invention is particularly intended to attenuate the production of clicks, at the level of the coupling heads of the trailers, when driving.
