Description

Dispositif de montage de roues, notamment pour brouettes
ou autres dispositifs de manutention
La présente invention concerne le domaine des véhicules de manutention, notamment du type brouette, et a pour objet un dispositif de montage de roues pour de tels véhicules.Wheel mounting device, especially for wheelbarrows
or other handling devices
The present invention relates to the field of handling vehicles, in particular of the wheelbarrow type, and relates to a wheel mounting device for such vehicles.

Actuellement, les roues des véhicules de manutention tels que brouettes, diables, etc... sont fixées généralement au châssis correspondant au moyen de paliers métalliques ou en matière plastique rigide comportant le plus souvent une carcasse coulée ainsi que, le cas échéant, des bagues de frottement et/ou des roulements. Currently, the wheels of handling vehicles such as wheelbarrows, hand trucks, etc. are generally fixed to the corresponding chassis by means of metal or rigid plastic bearings, most often comprising a cast carcass and, if appropriate, rings. friction and / or bearings.

Néanmoins, ces paliers sont d'un prix de revient non négligeable et transmettent intégralement les vibrations et les chocs générés au niveau de la ou des roues lors du déplacement dudit véhicule, d'où résulte un confort de manipulation très insuffisant. However, these bearings are of a non-negligible cost price and fully transmit the vibrations and shocks generated at the wheel or wheels during the movement of said vehicle, which results in very insufficient handling comfort.

Ces vibrations et ces chocs sont notamment très importants, en fréquence et en puissance, lorsque le véhicule considéré est pourvu de roues pleines, ces dernières étant toutefois particulièrement intéressantes du fait qu'elles sont increvables. These vibrations and these shocks are in particular very significant, in frequency and in power, when the vehicle in question is provided with solid wheels, the latter being however particularly advantageous because they cannot be punctured.

Le but de la présente invention est donc de concevoir un dispositif de montage de roues d'un prix de revient faible et permettant d'amortir au maximum les vibrations et les chocs générés lors du déplacement du véhicule, évitant ainsi leur transmission à l'utilisateur. The object of the present invention is therefore to design a wheel mounting device with a low cost price and making it possible to dampen as much as possible the vibrations and shocks generated during the movement of the vehicle, thus avoiding their transmission to the user. .

A cet effet, l'invention a pour objet un dispositif de montage de roues, en particulier pour véhicules de manutention tels que, par exemple, brouettes, caractérisé en ce que lraxe de la ou des roues est fixé au châssis du véhicule, avec assujettissement en rotation ou non, au moyen de paliers monoblocs réalisés en un matériau synthétique présentant des propriétés d'amortissement de vibrations. To this end, the subject of the invention is a device for mounting wheels, in particular for handling vehicles such as, for example, wheelbarrows, characterized in that the axis of the wheel or wheels is fixed to the chassis of the vehicle, with subjection in rotation or not, by means of one-piece bearings made of a synthetic material having vibration damping properties.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence au dessin schématique annexé, dans lequel
la figure 1 est une vue en perspective d'un palier faisant partie du dispositif de montage de roues conforme à l'invention et,
la figure 2 est une vue en perspective d'un dispositif de montage de roues conforme à l'invention appliqué à une roue de brouette.The invention will be better understood from the description below, which relates to preferred embodiments, given by way of non-limiting examples, and explained with reference to the appended schematic drawing, in which
FIG. 1 is a perspective view of a bearing forming part of the wheel mounting device according to the invention and,
Figure 2 is a perspective view of a wheel mounting device according to the invention applied to a wheelbarrow wheel.

Conformément à l'invention et comme le montre la figure 2 du dessin annexé, l'axe 2 de la ou des roues 1 est fixé au châssis 3 du véhicule, avec assujettissement en rotation ou non, au moyen de paliers 4 monoblocs réalisés en un matériau synthétique présentant des propriétés d'amortissement de vibrations. In accordance with the invention and as shown in FIG. 2 of the attached drawing, the axle 2 of the wheel or wheels 1 is fixed to the chassis 3 of the vehicle, with rotationally secured or not, by means of one-piece bearings 4 produced in a synthetic material with vibration damping properties.

Le matériau utilisé est avantageusement du polyuréthane haute densité, présentant préférentiellement un indice de dureté Shore compris entre 50 et 80. The material used is advantageously high density polyurethane, preferably having a Shore hardness index of between 50 and 80.

Selon une caractéristique de l'invention, représentée aux figures 1 et 2 du dessin annexé, les paliers 4 présentent essentiellement une forme de parallélépipède rectangle dont l'extrémité 5 comportant l'orifice 6 de réception de l'axe 2 est, le cas échéant, arrondie. According to a characteristic of the invention, shown in Figures 1 and 2 of the accompanying drawing, the bearings 4 essentially have the shape of a rectangular parallelepiped whose end 5 comprising the orifice 6 for receiving the axis 2 is, where appropriate , rounded.

Conformément à un premier mode de réalisation de l'invention et comme le montrent également les figures 1 et 2 du dessin annexé, les paliers 4 sont pourvus d'une cannelure périphérique 7, permettant leur assemblage avec le châssis 3 au moyen de bagues 8 correspondantes, réalisées par exemple en polyamide. According to a first embodiment of the invention and as also shown in Figures 1 and 2 of the accompanying drawing, the bearings 4 are provided with a peripheral groove 7, allowing their assembly with the chassis 3 by means of corresponding rings 8 , made for example of polyamide.

Selon un deuxième mode de réalisation de l'invention, non représenté au dessin annexé, les paliers 4 sont munis de pattes de fixation latérales comportant des orifices oblongs pour le passage de vis d'assemblage.  According to a second embodiment of the invention, not shown in the accompanying drawing, the bearings 4 are provided with lateral fixing lugs comprising oblong holes for the passage of assembly screws.

Dans le cas d'une fixation sur des châssis tubulaires, les paliers 4 sont avantageusement pourvus d'une rainure circulaire 9 au niveau de leur extrémité 10 appliquée contre ledit châssis 3 (figures 1 et 2). In the case of attachment to tubular frames, the bearings 4 are advantageously provided with a circular groove 9 at their end 10 applied against said frame 3 (Figures 1 and 2).

Conformément à une caractéristique supplémentaire de l'invention et afin d'augmenter la résistance à l'usure et aux chocs desdits paliers 4, les surfaces délimitant l'orifice 6 de réception de l'axe 2, la rainure circulaire 9 et la cannelure périphérique 7 présentent une dureté augmentée, obtenue, le cas échéant, par traitement thermique. In accordance with an additional characteristic of the invention and in order to increase the wear and impact resistance of said bearings 4, the surfaces delimiting the orifice 6 for receiving the axis 2, the circular groove 9 and the peripheral groove 7 have an increased hardness, obtained, if necessary, by heat treatment.

Grâce à l'invention, il est donc possible de réaliser un dispositif de montage de roues, présentant un coefficient d'amortissement des vibrations et des chocs important et une structure simple. Thanks to the invention, it is therefore possible to produce a wheel mounting device, having a high vibration and shock absorption coefficient and a simple structure.

Par ailleurs, du fait du matériau utilisé et de son mode de fabrication, son prix de revient est très peu élevé. Furthermore, due to the material used and its method of manufacture, its cost price is very low.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.  Of course, the invention is not limited to the embodiments described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
