Description

Dispositif d'attelage d'un véhicule automobile .   Coupling device for a motor vehicle

L'invention concerne un dispositif d'attelage équipant un véhicule automobile, notamment à l'arrière de celui-ci. The invention relates to a coupling device fitted to a motor vehicle, particularly at the rear thereof.

Généralement, un dispositif d'attelage comprend une traverse amoviblement fixée à la structure de carrosserie du véhicule par l'intermédiaire de deux flasques latéraux. Une boule d'attelage est amoviblement fixée à la traverse, sensiblement au milieu de celle-ci, par l'intermédiaire d'ensembles à vis de fixation et blocs de filtration en un matériau élastomère de façon à absorber ou filtrer les vibrations et chocs générés par les engins attelés, tels que remorques ou caravanes, au véhicule lors du démarrage ou du freinage du véhicule. Generally, a coupling device comprises a cross member removably attached to the vehicle body structure by means of two lateral flanges. A hitch ball is removably attached to the cross member, substantially in the middle thereof, by means of fixing screw assemblies and filtration blocks made of an elastomeric material so as to absorb or filter the vibrations and shocks generated. by harnessed implements, such as trailers or caravans, to the vehicle when starting or braking the vehicle.

Cependant, ce dispositif d'attelage connu peut également être utilisé pour recevoir un porte charge, par exemple d'une ou plusieurs bicyclettes, fixé à la traverse derrière le véhicule. Dans ces conditions, le filtrage des vibrations et chocs au niveau de la boule d'attelage n'est plus approprié. La présente invention a pour but de pallier les inconvénients ci-dessus en proposant un dispositif d'attelage d'un véhicule permettant également d'absorber les chocs et les vibrations générés par des charges portées par ce dispositif. A cet effet, l'invention a pour objet un dispositif d'attelage d'un véhicule automobile, comprenant une traverse fixée à la structure de carrosserie par l'intermédiaire de deux flasques latéraux, et caractérisé en ce que les deux flasques latéraux sont fixés à la structure de carrosserie du véhicule par l'intermédiaire de plusieurs blocs en un matériau de filtration ou d'absorption de chocs et de vibrations. Avantageusement, chaque bloc de filtration est réalisé 35 en matériau élastomère. De préférence, chaque bloc de filtration est de type silent bloc. However, this known coupling device can also be used to receive a load carrier, for example of one or more bicycles, attached to the cross member behind the vehicle. Under these conditions, the filtering of vibrations and shocks at the hitch ball is no longer appropriate. The present invention aims to overcome the above drawbacks by providing a coupling device of a vehicle also for absorbing shocks and vibrations generated by loads carried by this device. For this purpose, the invention relates to a coupling device of a motor vehicle, comprising a cross member fixed to the body structure by means of two lateral flanges, and characterized in that the two side plates are fixed to the body structure of the vehicle through several blocks of a filter material or shock absorption and vibration. Advantageously, each filtration unit is made of elastomeric material. Preferably, each filter unit is of the silent block type.

Selon une autre caractéristique de l'invention, chaque bloc de filtration est fixé entre le flasque latéral correspondant et la structure de carrosserie du véhicule par une vis de fixation. According to another characteristic of the invention, each filter unit is fixed between the corresponding lateral flange and the body structure of the vehicle by a fixing screw.

Alternativement, la traverse d'attelage est équipée d'une rotule d'attelage. Selon une autre caractéristique de l'invention, les deux flasques latéraux sont solidaires des deux extrémités de la traverse. Alternatively, the crossbar is equipped with a hitch ball. According to another characteristic of the invention, the two lateral flanges are integral with both ends of the crosspiece.

L'invention vise également un véhicule équipé d'un dispositif d'attelage tel que défini ci-dessus. L'invention sera mieux comprise et d'autres buts, avantages et caractéristiques de celle-ci apparaîtront plus clairement à la lecture de la description qui suit et qui est faite au regard des dessins annexés qui représentent des exemples non limitatifs de réalisation du dispositif de l'invention et sur lesquels : - la figure 1 est une vue de dessous de l'arrière d'un véhicule équipé d'un dispositif d'attelage conforme à l'invention ; la figure 2 est une vue de dessous agrandie en perspective d'une partie du dispositif d'attelage de l'invention ; et - la figure 3 est une vue en coupe selon la ligne III- III de la figure 2. En se reportant aux figures, la référence 1 désigne un dispositif d'attelage qui comprend une traverse d'attelage 2 fixée à ses deux extrémités opposées 3 et 4 par l'intermédiaire de flasques latéraux 5. The invention also relates to a vehicle equipped with a coupling device as defined above. The invention will be better understood and other objects, advantages and characteristics thereof will appear more clearly on reading the description which follows and which is made with reference to the accompanying drawings which show non-limiting examples of embodiment of the device of FIG. the invention and in which: - Figure 1 is a bottom view of the rear of a vehicle equipped with a coupling device according to the invention; Figure 2 is an enlarged bottom view in perspective of a portion of the coupling device of the invention; and FIG. 3 is a sectional view along the line III - III of FIG. 2. Referring to the figures, reference numeral 1 designates a coupling device which comprises a coupling crossmember 2 fixed at its two opposite ends. 3 and 4 via lateral flanges 5.

Chaque flasque latéral 5 est solidaire de l'extrémité correspondante 3, 4 de la traverse d'attelage 2 et comprend une première partie plane 8 fixée à la structure de carrosserie du véhicule par au moins une vis de fixation 7, dans le cas présent au nombre de deux, ancrée dans cette structure. Le flasque 5 comprend en outre une deuxième partie plane 10 s'étendant perpendiculairement à la première partie 8 et fixée à la structure de carrosserie en un emplacement situé en arrière du véhicule par rapport à la première partie 8 du flasque 5, par l'intermédiaire d'une ou plusieurs vis de fixation 7. Les deux parties 8 et 10 du flasque 5 sont reliées l'une à l'autre par une plaque intermédiaire 13 solidaire de l'extrémité correspondante 3, 4 de la traverse d'attelage 2. Les deux premières parties 8 et 10 des flasques 5 sont fixées aux faces inférieures respectivement de deux longerons 18 et 19 de la structure de carrosserie. Each lateral flange 5 is integral with the corresponding end 3, 4 of the crossbar 2 and comprises a first flat portion 8 fixed to the body structure of the vehicle by at least one fastening screw 7, in this case to number of two, anchored in this structure. The flange 5 further comprises a second flat portion 10 extending perpendicular to the first portion 8 and fixed to the body structure at a location behind the vehicle relative to the first portion 8 of the flange 5, via one or more fastening screws 7. The two parts 8 and 10 of the flange 5 are connected to one another by an intermediate plate 13 integral with the corresponding end 3, 4 of the crossbar 2. The first two portions 8 and 10 of the flanges 5 are fixed to the lower faces respectively of two longitudinal members 18 and 19 of the body structure.

La traverse 2 peut être équipée d'une boule d'attelage 21 fixée sensiblement au milieu de la traverse 2. Comme représenté, la boule 21 est fixée à l'extrémité d'une partie en col de cygne 23 solidaire de la traverse 2. Selon l'invention, les deux parties planes 8 et 10 d'extrémité de chaque flasque 5 sont fixées à la structure de carrosserie par l'intermédiaire de blocs 25 en matériau élastomère du genre silent blocs interposés entre chaque partie plane 8, 10 et la structure de carrosserie, et enserrés entre elles par les vis de fixation 7 traversant ces blocs 25. La présence de blocs 25 au niveau des points de fixation entre les flasques d'attelage 5 et la structure de carrosserie du véhicule permet de filtrer ou d'absorber les chocs et vibrations générés par des charges fixées sur la traverse d'attelage 2 derrière le véhicule, telles que par exemple des bicyclettes, améliorant de la sorte le confort du conducteur et des passagers du véhicule. The crossbar 2 may be equipped with a coupling ball 21 fixed substantially in the middle of the crossbar 2. As shown, the ball 21 is fixed to the end of a gooseneck portion 23 integral with the crossbar 2. According to the invention, the two flat end portions 8 and 10 of each flange 5 are fixed to the body structure by means of blocks 25 made of elastomer material of the silent block type interposed between each flat portion 8, 10 and the body structure, and clamped together by the fastening screws 7 passing through these blocks 25. The presence of blocks 25 at the attachment points between the coupling flanges 5 and the body structure of the vehicle allows to filter or absorb shocks and vibrations generated by loads fixed on the crossbar 2 behind the vehicle, such as for example bicycles, thus improving the comfort of the driver and passengers of the vehicle.
