Abstract

The hydrostatic drive unit consists of a hydrostatic pump (12) driven by the vehicle engine (11) to deliver fluid from a reservoir (13) through a pipe (14,17) to a fluid connector (18). Coupled to the connector (18) is a pipe (23) to a hydrostatic motor (22) to drive independent accessories, such as a circular saw, or an electricity generator. The motor supply pipe is provided with a flow regulator valve (24), to which is fitted a bypass pipe to return via the motor outlet pipe to a fluid return coupling (25) and back to the reservoir.

Description

L'invention part d'une commande hydrostatique comprenant une pompe hydraulique installée sur un véhicule tracteur sur un tracteur agricole par exemple, et mue par le moteur de propulsion de ce véhicule, qui alimente un moteur hydraulique. The invention starts from a hydrostatic control comprising a hydraulic pump installed on a tractor vehicle on an agricultural tractor for example, and driven by the propulsion engine of this vehicle, which supplies a hydraulic motor.

Le véhicule équipé d'une telle commande hydrostatique porte généralement plusieurs pompes hydrauliques et des moteurs hydrauliques, alimentés par elles, qui entraînent des appareils auxiliaires tels que des installations frigorifiques, une direction assistée et ainsi de suite. Cette disposition a l'inconvénient que seuls des appareils réliés de façon fixe au véhicule concerné peuvent être entraînés hydrauliquement. The vehicle equipped with such a hydrostatic control generally carries several hydraulic pumps and hydraulic motors, powered by them, which drive auxiliary devices such as refrigeration systems, power steering and so on. This arrangement has the disadvantage that only devices fixedly connected to the vehicle concerned can be driven hydraulically.

L'invention vise notamment à éviter cet inconvénient. The invention aims in particular to avoid this drawback.

A cet effet, selon l'invention, une commande hydrostatique comme défini ci-dessus est caractérisée en ce que le moteur hydraulique est installé sur un appareil séparé du véhicule tracteur et peut être relié à la pompe hydraulique par des raccords à liquide convenables.To this end, according to the invention, a hydrostatic control as defined above is characterized in that the hydraulic motor is installed on a device separate from the towing vehicle and can be connected to the hydraulic pump by suitable liquid connections.

Une telle commande hydrostatique a l'avantage, comparativement à l'art antérieur, que la pompe du véhicule peut servir à alimenter toutes sortes d'appareils ou machines séparés du véhicule et comportant un moteur hydraulique. On obtient ainsi une commande hydrostatique offrant de nombreuses possibilités d'application. Such a hydrostatic control has the advantage, compared to the prior art, that the vehicle pump can be used to power all kinds of apparatus or machines separate from the vehicle and comprising a hydraulic motor. A hydrostatic control is thus obtained, offering numerous possibilities of application.

I1 convient particulièrement de prévoir une soupape régulatrice de débit en amont du moteur hydraulique, de sorte que celui-ci peut travailler à une vitesse de rotation constante. It is particularly suitable to provide a flow regulating valve upstream of the hydraulic motor, so that the latter can work at a constant speed of rotation.

D'autres caractéristiques et avantages de l'invention ressortiront plus clairement de la description qui va suivre d'un exemple de réalisation non limitatif, ainsi que de la figure unique du dessin annexé, qui montre schématiquement une commande hydrostatique selon l'invention. Other characteristics and advantages of the invention will emerge more clearly from the description which follows of a nonlimiting exemplary embodiment, as well as from the single figure of the appended drawing, which schematically shows a hydrostatic control according to the invention.

Le dessin représente un véhicule tracteur 10 qui est propulsé par un moteur à combustion interne 11, lequel entraîne en même temps une pompe hydraulique 12. Celle-ci aspire du fluide de pression d'un réservoir 13 et le refoule dans une conduite d'alimentation 14 sur laquelle est monté, en dérivation, un limiteur de pression 15, d'où une conduite de retour 16 mène également au réservoir. De la conduite d'alimentation 14 part une conduite d'utilisateur 17 qui aboutit sur un raccord à liquide 18 sur le côté extérieur du véhicule tracteur. La référence 20 désigne un appareil qui est totalement indépendant du véhicule tracteur 10. Cet appareil peut comporter ou constituer, par exemple, une scie circulaire 21 qui est entraînée par un moteur hydraulique 22. Ce dernier est alimenté à travers une conduite d'utilisateur 23 qui est branchée sur le raccord à liquide 18.Une soupape régulatrice de débit 24 est installéeen amont du moteur hydraulique 22. A partir de celui-ci, une conduite de retour 25, qui peut également être branchée sur le véhicule tracteur à l'aide d'un raccord à liquide 26, mène au réservoir 13. The drawing shows a tractor vehicle 10 which is powered by an internal combustion engine 11, which at the same time drives a hydraulic pump 12. The latter sucks pressure fluid from a reservoir 13 and discharges it into a supply line. 14 on which is mounted, bypass, a pressure limiter 15, from which a return line 16 also leads to the tank. From the supply line 14 leaves a user line 17 which terminates on a liquid connection 18 on the outside of the towing vehicle. The reference 20 designates an apparatus which is completely independent of the towing vehicle 10. This apparatus may comprise or constitute, for example, a circular saw 21 which is driven by a hydraulic motor 22. The latter is supplied through a user line 23 which is connected to the liquid connection 18. A flow control valve 24 is installed upstream of the hydraulic motor 22. From this, a return line 25, which can also be connected to the towing vehicle using of a liquid connection 26, leads to the reservoir 13.

A condition que le débit de la pompe hydraulique 12 soit plus grand que le débit du moteur hydraulique 22, la soupape régulatrice de débit 24 assure l'entraînement du moteur hydraulique à vitesse de rotation constante. Le débit de fluide de pression excédentaire est refoulé dans la conduite de retour 25 à travers une conduite de dérivation 28 raccordée à la soupape régulatrice de débit 24. Provided that the flow rate of the hydraulic pump 12 is greater than the flow rate of the hydraulic motor 22, the flow control valve 24 drives the hydraulic motor at constant speed. The flow of excess pressure fluid is discharged into the return line 25 through a bypass line 28 connected to the flow control valve 24.

L'appareil 20 peut être un appareil ou une machine quelconque, par exemple une scie circulaire - comme décrit - , une hacheuse, un groupe électrogène, un compresseur ou des appareils ou machines analogues. I1 importe seulement que l'appareil soit muni d'un moteur hydraulique et des conduites ou tuyaux nécessaires pour le raccorder au véhicule tracteur 10.  The device 20 can be any device or machine, for example a circular saw - as described -, a chopper, a generator, a compressor or similar devices or machines. It is only important that the device is fitted with a hydraulic motor and the pipes or hoses necessary to connect it to the towing vehicle 10.
