Abstract

The thick section sheet casing (4) and base (1) of a driving wheel reducing hub for a high level tractor has its upper part fixed to the tractor axle (2). It contains the transmission chain (9) and control pinion in its upper part, the breather for avoiding air pressure and the driven pinion (5). It is sealed and contains lubrication oil. An eccentric monobloc plate (3) assembles the casing to the reduction hub (1). This hub has in its end the reduction gears. The chain tension is caused by rotation of the plate (3) and the eccentricity (8) between the chain and the driven pinion support is thus modified. The transmission shaft (2) of the reduction hub (1) has one end fluted which passes through the pinion (5). These flutings ensure transmission and rotation of the control shaft of the reduction hub

Description

La présente invention concerne un système de montage pour la fixation et le réglage de 1 'entraxe d'un moyeu de roue AR, comportant un réducteur par pignons satellites, sur un carter de tracteur enjambeur. The present invention relates to a mounting system for fixing and adjusting the center distance of a rear wheel hub, comprising a reduction gear with planet gears, on a straddle tractor housing.

La surélévation des tracteurs classiques en enjambeurs utilise généralement une chaîne de transmission. Elle travaille dans un carter faisant châssis. Certains montages présentent les inconvénients suivants: - Pas de bain d'huile mais un graissage manuel. The elevation of conventional tractors into straddles generally uses a transmission chain. It works in a casing forming a chassis. Some assemblies have the following drawbacks: - No oil bath but manual lubrication.

- Pas de réglage de tension de chaîne.- No chain tension adjustment.

- Une réduction de rapport de vitesse importante, d'où un petit pignon de camnande ayant peu de dents.- A significant reduction in speed ratio, resulting in a small pinion of camnande with few teeth.

- Un système de tendeur sur le brin mou de la chaîne, par galet ou patin de frottement. Cela nécessite du réglage et n'est pas souhaitable lors de grands efforts, ou à-coups en marche arrière.- A tensioner system on the soft end of the chain, by roller or friction shoe. This requires adjustment and is not desirable during great efforts, or jerks in reverse.

- Des moyeux à entraxe réglables ayant des glissières ou lumières avec tensions différentes de chaque côté du carter, sont difficiles à bien régler et risquent des fuites d'huile.- Hubs with adjustable spacing having slides or lights with different tensions on each side of the housing are difficult to adjust properly and risk oil leakage.

Le dispositif selon l'invention permet de remédier à ces inconvénients. The device according to the invention overcomes these drawbacks.

I1 comprend: - Un carter en mécano-soudure de forte section (tôle 8-12-25 mn.) Celuici est étanche et le même bain d'huile lubrifie à la fois: Le moyeu réducteur d'origine, ainsi que la chaîne, les pignons et roulements. Un reniflard empêche une pression d'air de provoquer des fuites d'huile aux joints. I1 includes: - A large section mechanical welding casing (sheet metal 8-12-25 min.) This is waterproof and the same oil bath lubricates both: The original reducing hub, as well as the chain, the pinions and bearings. A breather prevents air pressure from causing oil leaks at the seals.

- La fixation avec entraxe réglable du moyeu réducteur sur le carter se fait par un plateau monobloc excentré, fixé sur le côté extérieur. C'est simple et apporte l'avantage de supprimer le palier supplémentaire à l'intérieur du carter.- The fixing with adjustable center distance of the reduction hub on the casing is done by an eccentric monobloc plate, fixed on the outside. It is simple and has the advantage of eliminating the additional bearing inside the casing.

- Ce plateau sert également de support au pignon inférieur, qui a son tour, maintient ltextrémité de l'arbre du réducteur. I1 est ajouré pour permettre la circulation de 1' huile entre réducteur et carter.- This plate also serves as a support for the lower pinion, which in turn maintains the end of the reduction gear shaft. It is perforated to allow the circulation of the oil between the reduction gear and the crankcase.

- La tension de la chaîne peut être réglée par la rotation du plateau excentré, si dans le temps, cela est nécessaire.- The chain tension can be adjusted by rotating the eccentric plate, if necessary over time.

Ce plateau excentré maintient aussi: - Le moyeu réducteur de la roue motrice. This eccentric plate also maintains: - The reducing hub of the drive wheel.

- L'extrémité libre de l'arbre du moyeu réducteur.- The free end of the reduction hub shaft.

- le pignon de commande. - the drive pinion.

- L'arbre de commande traversant le pignon renforce 1 'assemblage et la rigidité de l'ensemble. - The control shaft passing through the pinion reinforces the assembly and the rigidity of the assembly.

Les dessins annexés illustrent l'invention:
La figure 1 représente en coupe la partie inférieure du carter 4 et l'embase 1 du moyeu réducteur de roue AR. motrice du tracteur enjambeur.The accompanying drawings illustrate the invention:
Figure 1 shows in section the lower part of the casing 4 and the base 1 of the rear wheel reducing hub. driving the straddle tractor.

La figure 2 représente de face le carter 4 et le plateau excentré 3. FIG. 2 represents the casing 4 and the eccentric plate 3 from the front.

le carter 4 est en mécano-soudure en tôle de forte section, indéformable et incassable, comparativement aux pièces en fonte. La partie supérieure non représentée sur le dessin est fixée au pont AR. du tracteur. Il contient la chaîne de transmission 9 le pignon de commande en partie haute, le reniflard pour éviter une pression d'air et le pignon de réception 5. I1 est étanche et contient l'huile pour la lubrification de l'ensemble. the casing 4 is made of mechanically welded sheet metal of large cross section, undeformable and unbreakable, compared to the cast iron parts. The upper part not shown in the drawing is fixed to the rear bridge. of the tractor. It contains the transmission chain 9, the control pinion in the upper part, the breather to avoid air pressure and the receiving pinion 5. I1 is sealed and contains the oil for the lubrication of the assembly.

le plateau excentré monobloc 3 assure les fonctions suivantes: - L'assemblage sur le carter 4 de l'embase de fixation du moyeu réducteur 1 des roues AR. motrices du tracteur. A l'origine, ce moyeu qui comporte dans son extrémité les pignons du réducteur, était fixé sur le pont du tracteur. the monobloc eccentric plate 3 performs the following functions: - The assembly on the casing 4 of the mounting base of the reduction hub 1 of the rear wheels. tractor drive. Originally, this hub, which has the gears of the reduction gear at its end, was fixed on the tractor deck.

- La tension de la chaîne 9 se fait par la rotation du plateau 3 qui est excentré 8 et modifie ainsi 1 'entraxe de celle-ci.- The tension of the chain 9 is done by the rotation of the plate 3 which is eccentric 8 and thus modifies the distance between them.

- Le support du pignon de réception 5 par l'intermediaire d'un roulement 6.- The support of the receiving pinion 5 by means of a bearing 6.

- La lubrification des organes du carter 4 et du moyeu réducteur 1 par le même bain d'huile grace aux orifices de cammunication 7.- The lubrication of the bodies of the casing 4 and of the reduction hub 1 by the same oil bath thanks to the cammunication orifices 7.

L'arbre de transmission 2 du moyeu réducteur d'origine 1 a une extrémité cannelée, qui traverse le pignon 5. Ces cannelures assurent la transmission de la rotation de l'arbre de commande 2 du moyeu réducteur 1 et renforcent la solidité du pignon 5 et de l'arbre 2.  The transmission shaft 2 of the original reducing hub 1 has a splined end, which passes through the pinion 5. These splines ensure the transmission of the rotation of the control shaft 2 of the reduction hub 1 and reinforce the solidity of the pinion 5 and tree 2.
