Description

509 166 2 En generator kan optimeras beträffande verkningsgraden på flera olika sätt, t.ex. genom att den förses med permanent- magneter, genom att yttre eller inre kylfläkt ersätts med exempelvis vätskekylning som medger värmeenergiâtervinning och genom att ingående komponenter optimeras för ett visst givet driftvarvtal. Härigenom kan generatorns medel- verkningsgrad höjas till mer än cirka 90 procent. På liknande sätt kan t.ex. luftkonditioneringens kylmedie- kompressor optimeras. Detta gäller i allmänhet även de flesta övriga förekommande hjälpapparater. 509 166 2 A generator can be optimized in terms of efficiency in several different ways, e.g. by providing it with permanent magnets, by replacing the external or internal cooling fan with, for example, liquid cooling which allows heat energy recovery and by optimizing the constituent components for a certain given operating speed. In this way, the generator's average efficiency can be increased to more than about 90 percent. Similarly, e.g. the air conditioning refrigerant compressor is optimized. This generally also applies to most other auxiliary devices.

Den normala drivningen av hjälpapparater via drivremmar som är anslutna till motoraxeln, är relativt utrymmeskrävande.The normal operation of auxiliary devices via drive belts connected to the motor shaft is relatively space-consuming.

Dessutom är driftsäkerheten hos drivremmar beroende av bl.a. korrekt justering. Om brott uppstår på en drivrem, kan fordonet behöva föras direkt till verkstad.In addition, the operational safety of drive belts depends on e.g. correct adjustment. If a breakage occurs on a drive belt, the vehicle may need to be taken directly to a workshop.

TEKNISKA PROBLEMET Ett ändamål med föreliggande uppfinning är att åstadkomma en anordning för drivning av hjälpapparater, med vilken ovan beskrivna nackdelar kan reduceras.TECHNICAL PROBLEM An object of the present invention is to provide a device for driving auxiliary devices, with which the above-described disadvantages can be reduced.

LÖSNINGEN För detta uppfinningen av att var och en av hjälpapparaterna är ändamål kännetecknas anordningen enligt ansluten till en hydraulisk drivmotor, som är inrättad att verka i huvudsak inom ett bestämt varvtalsomràde.THE SOLUTION For this invention that each of the auxiliary devices is for purposes, the device according to is connected to a hydraulic drive motor, which is arranged to operate substantially within a certain speed range.

BESKRIVNING AV RITNINGARNA Uppfinningen kommer nedan att beskrivas med hänvisning till utföringsexempel som visas på de bifogade ritningarna, på vilka Fig. 1 visar schematiskt i blockform ett drivsystem enligt uppfinningen, och Fig. 2 visar i perspektivvy en installation av uppfinningen vid en drivkälla. 509 166 3 BESKRIVNING AV UTFÖRINGSEXEMPEL I Fig. J. har med hänvisningsbeteckningen 10 angivits en drivkälla, t.ex. en förbränningsmotor, som kan verka direkt eller via en transmission för framdrivning av ett fordon.DESCRIPTION OF THE DRAWINGS The invention will be described below with reference to exemplary embodiments shown in the accompanying drawings, in which Fig. 1 shows diagrammatically in block form a drive system according to the invention, and Fig. 2 shows in perspective view an installation of the invention at a drive source. 509 166 3 DESCRIPTION OF EMBODIMENTS In Fig. J., the reference numeral 10 indicates a drive source, e.g. an internal combustion engine, which can operate directly or via a transmission for propelling a vehicle.

Som exempel på sådana fordon kan nämnas personbilar, bussar och lastbilar. En utgående axel ll pà motorn 10 kan vara ansluten till en transmission 12 som anpassar varvtalet på lämpligt sätt. Transmissionen 12 är i sin tur ansluten till en hydraulpump 13 som arbetar enligt principen variabelt deplacement.Examples of such vehicles are cars, buses and lorries. An output shaft 11 of the motor 10 may be connected to a transmission 12 which adjusts the speed appropriately. The transmission 12 is in turn connected to a hydraulic pump 13 which operates according to the principle of variable displacement.

Genom denna utformning av hydraulpumpen kan denna leverera ett väsentligen konstant hydraulvätskeflöde eller ett hydraulvätskeflöde med ett hydraulkrets 14, Hydraulkretsens 14 högtryckssida är betecknad med 15 och konstant tryck till en oberoende av drivkällans 10 varvtal. lågtryckssidan med 16. Ett tryckkärl 17 för lagring av hydraultryck är eventuellt anslutet till kretsens högtryckssida 15.Due to this design of the hydraulic pump, it can supply a substantially constant hydraulic fluid flow or a hydraulic fluid flow with a hydraulic circuit 14, The high pressure side of the hydraulic circuit 14 is denoted by 15 and constant pressure to an independent of the speed of the drive source 10. low pressure side with 16. A pressure vessel 17 for storing hydraulic pressure is optionally connected to the high pressure side 15 of the circuit.

Ett antal hydraulmotorer 18 är anslutna antingen i serie parallellt /parallellkoppling till hydraulsystemet. Var och en av dessa eller eller 'i en kombination av serie- hydraulmotorer 18 är ansluten» till en eller flera hjälpapparater 19. Hjälpapparaterna kan exempelvis utgöras av en generator för alstring av elektrisk ström, en kylmediekompressor för en luftkonditioneringsanläggning i fordonet, smörjoljepump, en vattenpump samt en kylfläkt för drivkällans kylsystem, servon för manövrering av koppling, styrning och bromsar, etc.. Samtliga hydraulmotorer 18 vilket innebär att de kan arbeta inom ett huvudsakligen konstant arbetar t.ex. enligt principen fast deplacement, varvtalsomràde. Alternativt kan de arbeta med variabelt deplacement. detta varvtalsomráde, vilket innebär att deras verkningsgrad kan Härigenom kan hjälpapparaterna optimeras för 509 166 4 ökas väsentligt, i jämförelse med om deras hastighet skulle vara helt beroende av drivkällans 10 varvtal. Exempelvis är det möjligt att erhålla en nædelverkningsgrad av mer än cirka 90 procent, vid en generator för alstring av elenergi, speciellt varvtalsomráde. om den optimeras för ett .Motsvarande gäller även för andra typer av hjälpapparater.A number of hydraulic motors 18 are connected either in series parallel / parallel connection to the hydraulic system. Each of these or or in a combination of series hydraulic motors 18 is connected 'to one or more auxiliary devices 19. The auxiliary devices may for example consist of a generator for generating electric current, a refrigerant compressor for an air conditioning system in the vehicle, lubricating oil pump, a water pump and a cooling fan for the cooling system's cooling system, servo for maneuvering the clutch, steering and brakes, etc .. All hydraulic motors 18, which means that they can work within a substantially constant operation, e.g. according to the principle of fixed displacement, speed range. Alternatively, they can work with variable displacement. this speed range, which means that their efficiency can Hereby the auxiliaries can be optimized for 509 166 4 significantly increased, in comparison with if their speed would be completely dependent on the speed of the drive source 10. For example, it is possible to obtain a needle efficiency of more than about 90 percent, with a generator for generating electrical energy, especially speed range. if it is optimized for a .The same applies to other types of auxiliary devices.

Olika drivvarvtal kan härvid åstadkommas genom val av hydraulmotor eller genom lämplig styrning/ reglering av denna. Man kan även tänka sig en transmission, t.ex. kuggväxel 20 eller remtransmission, som är kopplad mellan en ansluten annan till hydraulmotor hjälpapparat och en hjälpapparat.Different drive speeds can be achieved by selecting a hydraulic motor or by suitable control / regulation thereof. One can also imagine a transmission, e.g. gear 20 or belt transmission, which is connected between a connected other to the hydraulic motor auxiliary device and an auxiliary device.

Hydraulsystemet omfattar lämpligen styr- och reglerventiler 21 som kan manövreras mekaniskt, elektriskt, pneumatiskt, hydrauliskt eller med en kombination av någon/några av dessa sätt, för till- eller fránkoppling eller successiv (gradvis) till- hörande hydraulmotorer. Det är även möjligt att utforma eller fránkoppling av till olika hjälpapparater styr- och reglersystemet så, att det kommunicerar med fordonets styrdator eller annan regleranordning för drivkällan. Härvid kan hydraulmotorer kopplas från eller delvis ur vid manövrer som är kraftkrävande för fordonet, till exempel vid acceleration för omkörning, eller styras ned till en lägre nivå. Alternativt skulle drivkällan kunna beordras att öka sitt varvtal/uteffekt efter avrop beroende på förväntade händelser i systemet. På så sätt kan t.ex. luftkonditioneringssystemet begära. mer' av' drivkällan när kylkompressorn behöver starta/öka effekten. även en total- Det ovan beskrivna systemet möjliggör hydraulmotorer, generator, integrering av hydraulpump, vattenpump, kylkanaler med mera i form av höljesintegrering med drivmotorn. Härigenom kan ett kompakt hjälpapparatpaket åstadkommas. Detta kan, förutom ur energisynpunkt, även vara en fördelaktig lösning med hänsyn till utrymmesbesparing och krocksäkerhet. Fler än en hjälpapparat kan drivas av en och 509 166 samma hydraulmotor' om så önskas och önskat driftvarvtal medger, t.ex. via gemensam axel eller via lämplig kraftöverföring.The hydraulic system suitably comprises control and regulating valves 21 which can be operated mechanically, electrically, pneumatically, hydraulically or with a combination of any of these modes, for connection or disconnection or successive (gradual) associated hydraulic motors. It is also possible to design or disconnect the control and regulation system for various auxiliary devices so that it communicates with the vehicle's control computer or other control device for the drive source. In this case, hydraulic motors can be switched off or partially switched off during maneuvers that require force for the vehicle, for example during acceleration for overtaking, or steered down to a lower level. Alternatively, the power source could be ordered to increase its speed / output after call-off depending on expected events in the system. In this way, e.g. the air conditioning system request. more 'off' the power source when the refrigeration compressor needs to start / increase the power. also a total- The system described above enables hydraulic motors, generator, integration of hydraulic pump, water pump, cooling ducts and more in the form of housing integration with the drive motor. In this way a compact auxiliary device package can be achieved. This can, in addition to being an energy point of view, also be an advantageous solution with regard to space savings and crash safety. More than one auxiliary device can be driven by one and the same hydraulic motor if desired and the desired operating speed allows, e.g. via common shaft or via suitable power transmission.

Tryckkärlet 17 kan t.ex. användas som energilager, för utnyttjande när extra kraft behövs, t.ex. vid start från stillastående, vid omkörning, eller när fordonet skall flyttas en kort sträcka utan att drivkällan behöver startas, t.ex. rangeringskörning inomhus. Den lagrade energin kan även användas för styrservon samt för start av drivkällan.The pressure vessel 17 can e.g. be used as energy storage, for utilization when extra power is needed, e.g. when starting from a standstill, when overtaking, or when the vehicle is to be moved a short distance without having to start the drive source, e.g. shunting driving indoors. The stored energy can also be used for the power steering and for starting the drive source.

Energi kan lagras i tryckkärlet 17 när det finns överskott, t.ex. då fordonet har momentöverskott (bromsenergiåter- vinning) eller då drivkällan har momentöverskott eller sin bästa verkningsgrad.Energy can be stored in the pressure vessel 17 when there is excess, e.g. when the vehicle has excess torque (brake energy recovery) or when the drive source has excess torque or its best efficiency.

Det ovan beskrivna systemet ger även möjlighet att ta tillvara kyleffekt från hydraulkomponenterna och hjälp- apparaterna och överföra denna till de delar av fordonet och/eller dess drivkälla där den kan nyttiggöras. Ett exempel på detta är integrering med drivkällans kylsystem för att snabbt erhålla lämplig drifttemperatur samt för att underlätta uppvärmning av fordonets kupéutrymmen.The system described above also makes it possible to utilize cooling power from the hydraulic components and auxiliary devices and transfer this to the parts of the vehicle and / or its drive source where it can be utilized. An example of this is integration with the drive system's cooling system in order to quickly obtain a suitable operating temperature and to facilitate heating of the vehicle's passenger compartments.

Den i Fig. 2 visade installationen av drivanordningen enligt uppfinningen åskådliggör en tvärställd drivkälla lO sedd snett framifrån och försedd med växellåda 22. En integrerad hydraulenhet 23 placerad rakt ovanför växellådan 22. Hydraulenheten 23 bär omfattande pump och hydraulsystem är i sin tur ett antal hjälpapparatenheter 24 som var och en kan omfatta en hydraulmotor 18 och minst en hjälpapparat 19.The installation of the drive device according to the invention shown in Fig. 2 illustrates a transverse drive source 10 seen obliquely from the front and provided with gearbox 22. An integrated hydraulic unit 23 located directly above the gearbox 22. The hydraulic unit 23 carries extensive pump and hydraulic system is in turn a number of auxiliary device units 24 each of which may comprise a hydraulic motor 18 and at least one auxiliary device 19.

Genom den hydrostatiska kraftöverföringen kan hjälp- apparaterna placeras på fördelaktiga positioner i fordonet och enkelt anslutas medelst t.ex. kanaler, rörledningar eller högtrycksslangar. Dessutom kan man ha gemensamma kyl- /värmekanaler i hydraulenheten 23, hjälpapparatenheten 24 och drivkällan. 509 166 6 Ur krocksynpunkt kan den ,massa som är bunden i hydraulmotorer och hjälpapparater placeras så att den gör största möjliga nytta vid en eventuell sammanstötning.Through the hydrostatic power transmission, the auxiliary devices can be placed in advantageous positions in the vehicle and easily connected by means of e.g. ducts, pipelines or high pressure hoses. In addition, one can have common cooling / heating ducts in the hydraulic unit 23, the auxiliary unit 24 and the drive source. 509 166 6 From a collision point of view, the mass bound in hydraulic motors and auxiliary devices can be placed so that it makes the greatest possible benefit in the event of a collision.

Uppfinningen är ej begränsad till de ovan beskrivna utföringsexemplen, utan flera varianter är tänkbara inom ramen för efterföljande krav. Exempelvis behöver hydraul- systemet inte vara försett med en energilagringstank. Vidare är det möjligt att använda arbetstrycket i hydraulsystemet för reducering av transmissionsljud som uppstår vid manövrering av ett fordons växellåda, genom anpassning av rörelsehastigheten hos ingående delar i transmissionenThe invention is not limited to the embodiments described above, but several variants are conceivable within the scope of the following claims. For example, the hydraulic system does not need to be equipped with an energy storage tank. Furthermore, it is possible to use the working pressure in the hydraulic system to reduce transmission noise which occurs when operating a vehicle's gearbox, by adjusting the speed of movement of the components in the transmission
