Description

Le brevet principal décrit un appareil auxiliaire d'entrainement pour remorque, du type qui comprend un châssis mobile portant un essieu tourillonnant autour d'un premier axe destiné à être sensiblement parallèle au sol et un dispositif d'entrainement manuel de l'essieu, ce dispositif ayant un organe mené directement monté sur 11 essieu, un châssis fixe comportant un organe de fixation à une remorque, un dispositif d'articulation du châssis mobile sur le châssis fixe autour d'un axe sensiblement perpendiculaire au premier axe et destiné à être sensiblement perpendiculaire au sol, ce dispositif comprenant un tronçon de tube de section circulaire solidaire du châssis mobile et un tronçon de tube de section circulaire solidaire du châssis fixe, les tronçons de tube étant montés télescopi ouement, un dispositif de réglage en translation des deux tronçons de tube, le châssis mobile étant sensiblement vertical et disposé près de l'axe d'articulation, et un dispositif de blocage temporaire en rotation du châssis mobile par rapport au châssis fixe. The main patent describes an auxiliary drive device for a trailer, of the type which comprises a mobile chassis carrying an axle swiveling around a first axis intended to be substantially parallel to the ground and a manual drive device for the axle, this device having a driven member directly mounted on 11 axles, a fixed frame comprising a member for fixing to a trailer, a device for articulating the movable frame on the fixed frame around an axis substantially perpendicular to the first axis and intended to be substantially perpendicular to the ground, this device comprising a tube section of circular section secured to the movable frame and a tube section of circular section secured to the fixed frame, the tube sections being mounted telescopically, a device for adjusting the translation of the two sections of tube, the movable chassis being substantially vertical and arranged near the hinge axis, and a temporary locking device in rotation of the mobile chassis relative to the fixed chassis.

L'expérience montre que cet appareil auxiliaire d'entrainement donne tout à fait satisfaction, notamment dans le cas des caravanes moyennes et légères. Cependant, on s'est rendu compte que, dans le cas des remorqueslourdes et surtout lorsque l'opérateur est une personne âgée ou disposant d'une force limitée, la manoeuvre pouvait nécessiter un effort trop important. Experience shows that this auxiliary training device is entirely satisfactory, especially in the case of medium and light caravans. However, it has been realized that, in the case of heavy trailers and especially when the operator is an elderly person or having a limited force, the maneuver could require too much effort.

Le présent certificat d'addition concerne donc un appareil auxiliaire d'entraînement pour remorque du type décrit dans le brevet principal, mais dans lequel le dispositif d'entratnement de l'essieu comporte un moteur ou un motoréducteur assistant la manoeuvre de l'appareil. The present certificate of addition therefore relates to an auxiliary drive device for a trailer of the type described in the main patent, but in which the axle drive device comprises a motor or a geared motor assisting the operation of the device.

Il s'agit de préférence d'un moteur électrique. It is preferably an electric motor.

Compte tenu des vitesses de sortie des moteurs électriques, il est souhaitable qu'il s'agisse d'un motoréducteur. Le moteur électrique est avantageusement un moteur à courant continu, destiné à fonctionner avec une tension d'alimentation couramment utilisée pour les batteries d'accumulateurs des véhicules tracteurs de ces remorques, c'est-à-dire essentiellement 12 volts, mais pouvant être parfois de 6 volts ou 24 volts.Given the output speeds of electric motors, it is desirable that it be a geared motor. The electric motor is advantageously a direct current motor, intended to operate with a supply voltage commonly used for storage batteries of the towing vehicles of these trailers, that is to say essentially 12 volts, but which can sometimes be 6 volts or 24 volts.

Le moteur du dispositif d'entrainement de l'essieu comporte avantageusement des organes permettant sa commande, tels qu'un interrupteur général, un inverseur de marche avant-arrière, des fusibles de protection, etc., qui sont avantageusement logés dans un coffret étanche qui protège aussi le moteur. The motor of the axle drive device advantageously comprises members allowing its control, such as a general switch, a reverse-reverse switch, protective fuses, etc., which are advantageously housed in a sealed box. which also protects the engine.

Le moteur du dispositif d'entraînement de l'essieu peut être monté directement sur l'essieu. Dans une variante, il est monté sur un arbre distant de l'essieu et de préférence parallèle à celui-ci, par exemple l'arbre portant la manivelle dans l'appareil décrit dans le brevet principal. The axle drive motor can be mounted directly on the axle. In a variant, it is mounted on a shaft distant from the axle and preferably parallel to the latter, for example the shaft carrying the crank in the device described in the main patent.

Il est avantageux que le moteur du dispositif d'entraînement ait un arbre qui a une première extrémité destinée à entraîner l'essieu, directement ou non, et une seconde extrémité permettant le montage d'une manivelle afin que, en cas de panne du moteur ou de son alimentation électrique, l'appareil puisse être manoeuvré. It is advantageous that the motor of the drive device has a shaft which has a first end intended to drive the axle, directly or not, and a second end allowing the mounting of a crank so that, in the event of motor failure or its power supply, the device can be operated.

Plus précisément, un appareil auxiliaire d'entraînement selon la présente addition peut être du type représenté sur la figure 1 du brevet principal. Plus précisément, dans cet appareil, la manivelle 70 est supprimée et 11 arbre sur lequel est monté le pignon 68 constitue l'arbre de sortie d'un motoréducteur à courant continu dont la tension est adaptée à celle des batteries d'accumulateurs du véhicule tracteur (par exemple 12'V). Le motoréducteur a avantageusement un couple de sortie d'au moins 2 N.m. L'équipement électrique associé au motorêducteur comporte avantageusement un interrupteur général, un inverseur de marche avant-arrière et des fusibles de protection. Eventuellement, un variateur de vitesse peut aussi être associé.Tous ces éléments, y compris le motoréducteur, sont avantageusement montés sur un socle lui-inême fixé par exemple sur la barre 22 du châssis mobile 20 de la figure 1 du brevet principal. Un coffret étanche est avantageusement placé autour de ces éléments et les protège. More specifically, an auxiliary drive device according to the present addition can be of the type shown in Figure 1 of the main patent. More specifically, in this device, the crank 70 is omitted and 11 shaft on which the pinion 68 is mounted constitutes the output shaft of a direct current gear motor whose voltage is adapted to that of the storage batteries of the towing vehicle (for example 12'V). The gearmotor advantageously has an output torque of at least 2 N.m. The electrical equipment associated with the gearmotor advantageously comprises a general switch, a forward-reverse reverser and protective fuses. Optionally, a variable speed drive can also be associated. All of these elements, including the gearmotor, are advantageously mounted on a base itself fixed for example on the bar 22 of the movable frame 20 of FIG. 1 of the main patent. A waterproof box is advantageously placed around these elements and protects them.

Un enrouleur de câble de type bien connu des hommes du métier, ayant avantageusement une prise normalisée pouvant se brancher directement sur une prise du véhicule tracteur, est aussi monté de préférence sur le châssis mobile. A cable reel of the type well known to those skilled in the art, advantageously having a standardized socket which can be plugged directly into a socket on the towing vehicle, is also preferably mounted on the mobile chassis.

Lorsque l'appareil est du type à une seule roue, par exemple décrit dans le premier certificat d'addition au brevet principal, le moteur ou motoréducteur est avantageusement monté directement sur l'essieu, à l'extrémité. When the device is of the single-wheel type, for example described in the first certificate of addition to the main patent, the motor or geared motor is advantageously mounted directly on the axle, at the end.

de celui-ci qui ne porte pas déjà- la roue unique. of it which does not already carry the single wheel.

Il est avantageux que l'extrémité de l'arbre du motoréducteur qui est opposée à celle qui assure l'entrainement de l'appareil, dépasse du boîtier du motoréducteur ou du coffret étanche et permette le montage d'une manivelle analogue à la manivelle 70 représentée sur la figure 1 du brevet principal. De cette manière, en cas de panne d'alimentation ou du moteur ou motoréducteur, l'appareil peut être utilisé manuellement. It is advantageous that the end of the gearmotor shaft which is opposite to that which drives the device, protrudes from the gearmotor housing or the sealed box and allows the mounting of a crank similar to crank 70 shown in Figure 1 of the main patent. In this way, in the event of a power or motor or gearmotor failure, the device can be used manually.

Bien qu'on ait décrit un exemple d'appareil muni d'un moteur électrique à courant continu, de nombreuses variantes peuvent être réalisées. Par exemple, le moteur électrique peut être de type alimenté en courant alternatif. Although an example of a device provided with a direct current electric motor has been described, numerous variants can be produced. For example, the electric motor can be of the type supplied with alternating current.

En outre, il n'est pas nécessaire que le moteur soit de type électrique, et d'autres types de moteurs, par exemple à combustion interne, peuvent être utilisés. In addition, the engine need not be of the electric type, and other types of engines, for example internal combustion, can be used.
