Abstract
Description
La présente invention a trait à un treuil à câble pour la manutention de la roue de secours d'un véhicule, particulièrement d'un camion et permettant au conducteur de changer ladite roue sans aucune aide supplémentaire. The present invention relates to a cable winch for handling the spare wheel of a vehicle, particularly a truck and allowing the driver to change said wheel without any additional assistance.
On conna,t des treuils de ce genre qui comprennent généralement une poulie à channe ou à câble, mais qui ne garantissent pas au conducteur toutes les sécurités d'utilisation. En effet, les treuils comportent certains inconvénients en ce qui concerne les difficultés de mise en place et de fixation de la roue de secours, ainsi que l'accès au dispositif d'entrainement du treuil. Known winches of this kind which generally include a pulley or cable or rope, but which do not guarantee the driver all the safety of use. Indeed, winches have certain drawbacks with regard to the difficulties of setting up and fixing the spare wheel, as well as access to the winch drive device.
C'est à ces inconvénients qu'entend plus spécialement remédier la présente invention
Le treuil à câble suivant l'invention comporte deux flasques parallèles en forme de L qui sont réunis l'un à l'autre dans leur partie horizontale par deux profilés en forme de U de manière à constituer lors de la fixation des flasques contre le châssis horizontal du véhicule deux espaces distincts pour la mise en place respectivement d'un dispositif d'entra,nement à pignon et vis sans fin pour la manipulation de la roue et d'un cric de levage hydraulique.It is to these drawbacks that the present invention more specifically intends to remedy.
The cable winch according to the invention comprises two parallel L-shaped flanges which are joined to each other in their horizontal part by two U-shaped profiles so as to constitute during the fixing of the flanges against the chassis horizontal of the vehicle two separate spaces for the installation respectively of a drive device, pinion and worm for handling the wheel and a hydraulic lifting jack.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue en perspective représentant le treuil à câble suivant la présente invention
Fig. 2 est une coupe verticale montrant les deux espaces distincts et le dispositif d'entrainement du treuil à câble.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is a perspective view showing the cable winch according to the present invention
Fig. 2 is a vertical section showing the two separate spaces and the device for driving the cable winch.
On a représenté en fig. 1 et 2 un treuil à câble 1 qui est fixé perpendiculairement sur un longeron horizontal 2 du châssis d'un camion pour la retenue et la manipulation d'une roue de secours 3. There is shown in fig. 1 and 2 a cable winch 1 which is fixed perpendicularly to a horizontal spar 2 of the chassis of a truck for retaining and handling a spare wheel 3.
Le treuil à câble est pourvu de deux flasques 4 et 5 qui sont réunis parallèlement l'un à l'autre au moyen de deux profilés 6 et 7 en forme de U. Les profilés 6 et 7 comportent respectivement des parois verticales 6a, 6b et 7a, 7b dont celles référencées 6a et 7b sont solidaires L'une de l'autre. En effet, la paroi 7b est recourbée sans sa partie supérieure pour venir envelopper le bord libre de la paroi 6a du profilé 6. The cable winch is provided with two flanges 4 and 5 which are joined in parallel to each other by means of two U-shaped profiles 6 and 7. The profiles 6 and 7 respectively have vertical walls 6a, 6b and 7a, 7b of which those referenced 6a and 7b are integral with one another. Indeed, the wall 7b is curved without its upper part to come to wrap the free edge of the wall 6a of the profile 6.
Les flasques 4 et 5 comportent chacun des ailes dirigées vers l'extérieur 4a, 4b, 5a, 5b suivant le même profil en forme de L. Les ailes 4a et 5a permettent la fixation du treuil 1 sur le longeron 2 du châs sis, tandis que les ailes 4b et 5b reçoivent le voile 3a de la roue 3 afin de la retenir en position haute. The flanges 4 and 5 each have wings directed towards the outside 4a, 4b, 5a, 5b according to the same L-shaped profile. The wings 4a and 5a allow the attachment of the winch 1 to the spar 2 of the chassis, while that the wings 4b and 5b receive the web 3a of the wheel 3 in order to retain it in the high position.
Le bord libre de la paroi 7a du profilé 7 est conformé pour constituer un coin 7c formant charnière. Autour du coin 7c pivote un couvercle cintré 9 permettant de fermer le treuil 1 L'extrémité libre du couvercle 9 vient en appui contre la paroi verticale 6a du profilé 6, de manière à pouvoir verrouiller ledit couvercle au moyen par exemple d'une vis. The free edge of the wall 7a of the profile 7 is shaped to form a corner 7c forming a hinge. Around the corner 7c pivots a curved cover 9 making it possible to close the winch 1 The free end of the cover 9 comes to bear against the vertical wall 6a of the profile 6, so as to be able to lock said cover by means for example of a screw.
Dans le fond du profilé 6 est percé un trou débouchant 6c qui est bordé latéralement par des chapes verticales 6d. Les chapes 6d sont disposées perpendiculairement aux parois verticales 6a, 6b du profilé 6 et parallèlement aux flasques 4 et 5 du treuil 1. Chacune des chapes 6d est prévue d'une hauteur inférieure à celle des parois du profilé 6 et comporte une encoche ouverte 6e pour le guidage de l'axe d'une roue dentée 11. In the bottom of the profile 6 is drilled a through hole 6c which is bordered laterally by vertical yokes 6d. The yokes 6d are arranged perpendicular to the vertical walls 6a, 6b of the profile 6 and parallel to the flanges 4 and 5 of the winch 1. Each of the yokes 6d is provided with a height less than that of the walls of the profile 6 and has an open notch 6th for guiding the axis of a toothed wheel 11.
La roue dentée 11 est solidaire d'un tambour 11a permettant l'enroulement d'un câble 12 dont l'extrémité libre est pourvue d'une boucle renforcée 12a. Une plaque 13 de forme rectangulaire est percée d'un trou central 13a dans lequel vient se loger la boucle 12a, de manière qu'elle coopère avec un doigt de retenue 14 solidaire de ladite plaque. La boucle 12a est libre en rotation autour du doigt 14 afin de pouvoir incliner la plaque 13 lors de son utilisation, comme on le verra mieux plus loin. La plaque 13 comporte dans chacun de ses angles un goujon taraudé 13b dirigé vers le haut qui vient s'engager dans les trous du voile 3a de la roue 3 et dans ceux des ailes 4b et 5b des flasques 4 et 5. The toothed wheel 11 is integral with a drum 11a allowing the winding of a cable 12 whose free end is provided with a reinforced loop 12a. A plate 13 of rectangular shape is pierced with a central hole 13a in which is housed the loop 12a, so that it cooperates with a retaining finger 14 integral with said plate. The loop 12a is free to rotate around the finger 14 so as to be able to tilt the plate 13 during its use, as will be seen more clearly below. The plate 13 has in each of its angles a threaded stud 13b directed upwards which engages in the holes of the web 3a of the wheel 3 and in those of the wings 4b and 5b of the flanges 4 and 5.
La roue dentée 11 engrène dans sa partie supérieure avec une vis sans fin 15 qui est guidée axialement dans les parois verticales 6a, 6b du profilé 6 par l'intermédiaire d'un axe d'entra,nement 16. L'une des extrémités libres de L'axe d'entrainement 16 débouche à l'extérieur du profilé 6 pour se prolonger en dehors du treuil 1 et présenter une forme de manivelle de manière à faciliter au conducteur la manipulation du dispositif d'entrainement. The toothed wheel 11 meshes in its upper part with an endless screw 15 which is guided axially in the vertical walls 6a, 6b of the profile 6 by means of a drive axis 16. One of the free ends of the drive shaft 16 opens outside of the profile 6 to extend outside of the winch 1 and have a crank shape so as to facilitate the driver handling the drive device.
On sait que la géométrie des dentures de la vis sans fin 15 et de la roue dentée 11 rend ce mécanisme irréversible, c'est-à-dire que la rotation de la vis entrain celle de la roue dentée 11, alors que l'inverse est impossible. We know that the geometry of the teeth of the worm 15 and the gear 11 makes this mechanism irreversible, that is to say that the rotation of the screw causes that of the gear 11, while the reverse is impossible.
L'espace prévu entre les parois verticales 7a, 7b du profilé 7 est prévu pour recevoir un cric hydraulique 18 connu en soi. The space provided between the vertical walls 7a, 7b of the profile 7 is provided to receive a hydraulic jack 18 known per se.
Le fonctionnement du treuil à câble 1 décrit précédemment est le suivant
Lorsqu'on veut disposer de la roue de secours 3 dont le voile 3a est pris en sandwich entre la plaque 13 et les ailes 4b et 5b des flasques 4 et 5 du treuil 1, on dévisse les écrous des goujons 13b pour libérer la plaque 13 des flasques 4 et 5. Ensuite, on entraine la vis sans fin 15 à l'aide de l'axe 16 en forme de manivelle dans le sens correspondant à l'abaissement de la roue 3.The operation of the cable winch 1 described above is as follows
When we want to have the spare wheel 3 whose web 3a is sandwiched between the plate 13 and the wings 4b and 5b of the flanges 4 and 5 of the winch 1, we unscrew the nuts of the studs 13b to release the plate 13 flanges 4 and 5. Then, the worm 15 is driven using the crank pin 16 in the direction corresponding to the lowering of the wheel 3.
On amène la roue 3 jusqu a ce qu'elle repose sur le sol et on descend encore légèrement la plaque 13 pour que les goujons 13b se dégagent des trous prévus dans le voile 3a. La plaque 13 est retirée du voile 3b par son orifice central et le conducteur peut alors disposer de la roue de secours. Pour remettre en place la roue 3 sur le véhicule, il suffit d'opérer en sens inverse. On introduit la plaque 13 sous le voile 3a de La roue 3 par son orifice central et on fait correspondre les goujons 13b avec les trous prévus sur la périphérie du voile. Ensuite, il suffit de remonter à l'aide de l'axe 16 en forme de manivelle jusqu'à ce que le voile de La roue 3 soit pris en sandwich entre les flasques 4 et 5 du treuil 1. The wheel 3 is brought until it rests on the ground and the plate 13 is lowered again slightly so that the studs 13b are released from the holes provided in the web 3a. The plate 13 is removed from the web 3b through its central orifice and the driver can then dispose of the spare wheel. To replace the wheel 3 on the vehicle, simply operate in reverse. The plate 13 is introduced under the web 3a of the wheel 3 through its central orifice and the studs 13b are made to correspond with the holes provided on the periphery of the web. Then, it suffices to go back using the crank-shaped pin 16 until the web of the wheel 3 is sandwiched between the flanges 4 and 5 of the winch 1.
On note que pour des roues de camion d'un diamètre inférieur on utilise une plaque 13' de plus petites dimensions, représentée en fig. 2 en traits mixtes et comportant uniquement deux goujons dirigés vers le haut qui coopèrent avec les trous ménagés dans les ailes 4b et 5b. It is noted that for truck wheels with a smaller diameter, a plate 13 'of smaller dimensions is used, shown in FIG. 2 in phantom and comprising only two studs directed upwards which cooperate with the holes made in the wings 4b and 5b.
il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. it should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
