Description
455 122 skjutbart fäst pà mellanväggen och till vilken hör cirkelring- formade polskor, som i den drivna höljesväggen till den hydrauliska kopplingen ligger axiellt, motbelägna och axiellt motsatt vilka i sin tur ligger motsvarande cirkelringformiga polskor på den drivande kilremskivan, vilken bildas av ändytan av den hylsformiga förlängningen och en på denna an- bragt polsko, varvid förlängningen ligger radiellt utanför och polskon radiellt innanför den elektromagnetiska spolen och sträcker sig över denna i hela dess längd. 455 122 slidably attached to the partition wall and to which belong circular ring-shaped pole shoes, which in the driven casing wall of the hydraulic coupling lie axially, opposite and axially opposite which in turn correspond to circular ring-shaped pole shoes on the driving V-belt disc, which is formed by the end surface of the the sleeve-shaped extension and a pole shoe mounted thereon, the extension lying radially outside and the pole shoe radially inside the electromagnetic coil and extending over it throughout its length.
Den enligt uppfinningen utförda hydrauliska kopplingen med fyllningsreglering uppvisar den fördelen att den elektro- magnetiska spolen är omgiven av polskor genom vilka det magnetiska fältet förs kortaste vägen till ventilens omkrets.The hydraulic coupling with filling control made according to the invention has the advantage that the electromagnetic coil is surrounded by pole shoes through which the magnetic field is carried the shortest way to the circumference of the valve.
Då denna utformning knappast uppvisar något magnetiskt sprid- ningsfält och inga ytterligare konstruktionsdelar heller måste genomflytas, behöver man bara en elek- tromagnetisk spole med-låg effekt. Konstruktionsdelar som är anordnade i omedelbar närhet av den elektromagnetiska spolen pâverkas icke av magnetfältet. Dä en hydraulisk koppling för motorfordon såsom känt endast erfordras under ca 5 % av den totala körtiden erhålls genom den uppfinningsmässiga utformningen en betydande energibesparing då den elektromagnetiska spolen genomflytes av ström endast då fläkten måste vara igång. _ Uppfinningen beskrivs närmare nedan under hänvisning till bifogade ritning, på vilken fig 1 visar en längdsektion genom en hyd- raulisk koppling och en drivenhet och fig 2 visar en detaljerad vy av ventilen vid en öppning, sett i påsiktsvy enligt pilen A i fig 1.Since this design hardly has any magnetic scattering field and no additional structural parts have to be traversed, all that is needed is a low-power electromagnetic coil. Structural parts arranged in the immediate vicinity of the electromagnetic coil are not affected by the magnetic field. Since a hydraulic coupling for motor vehicles as known is only required for about 5% of the total driving time, the inventive design provides a significant energy saving when the electromagnetic coil is flowed by current only when the fan must be running. The invention is described in more detail below with reference to the accompanying drawing, in which Fig. 1 shows a longitudinal section through a hydraulic coupling and a drive unit and Fig. 2 shows a detailed view of the valve at an opening, seen in a view according to arrow A in Fig. 1.
En i fig 1 visad axel 1 har lagertappar 1a, 1b och 1c. På lagertappen 1a är anordnad en hydraulisk koppling 2, medan på lager- tappen 1b vilar ett vridfast anbragt drivelement 3 och på lagertappen 1c är anordnat ett ringformigt vinkelstöd 4, på vilket är fäst ett hus 5, i vilket är ingjuten en spole 6 med ett vatten- och oljeavvi- sande medel 7. Den hydrauliska kopplingen 2 omfattar husdelar 8, 9 och en mellanvägg 10 med åtminstone en öppning 11, som är tillslut- bar medelst en ventil 12. Mellanväggen 10 delar ett medieinnehållande utrymme i den hydrauliska kopplingen 2 i en förràdskammare 13 och en drivkammare 14. I drivkammaren 14 är anordnad en friktionsskiva 15, som är vridbart fäst på en drivfläns 16, vilken vilar vridfast på lagertappen 1a. Husdelen 8 till den hydrauliska kopplingen 2 är an- 455 122 ordnad vridbar medelst ett lager 17 på drivflänsen 16. Lagret 17 av- skärmas gentemot det i arbetskammaren 14 befintliga mediet medelst en tätning 18. ventilen 12 är fäst vid mellanväggen 10 intill driv- flänsen 16 och mellanväggen uppvisar vid 19 en borrning 20 som för- binder arbetskammaren 14 och förrådskammaren 13. Husdelen 9 uppvisar intill öppningen 11 en av magnetiskt icke ledande material bestående distansring 21, som är fäst vid polskor 9a, 9b. Drivenheten 3 inne- fattar en kilremskiva 22 med en hylsliknande förlängning 23, som bildar en polsko, en av magnetiskt oledande material bestående dis- tansring 24, en polsko 25 och en av konstruktionsdelar 26, 27 beståen- de fästfläns 28, vilka är vridfast förbundna med varandra. Mellan pol- skorna 9a, 9b, till vilka ventilen 12 hör, och polskorna 23, 24, som hör till den elektromagnetiska spolen 6, befinner sig en luftspalt 30. En axiell förskjutning av den hydrauliska kopplingen 2 och driv- elementet 3 förhindras medelst en vid änden av axeln 1 befintlig, fastskruvbar säkringsanordning 29.A shaft 1 shown in Fig. 1 has bearing pins 1a, 1b and 1c. On the bearing pin 1a a hydraulic coupling 2 is arranged, while on the bearing pin 1b a rotationally arranged drive element 3 rests and on the bearing pin 1c is arranged an annular angular support 4, to which is mounted a housing 5, in which a coil 6 with a water and oil repellent means 7. The hydraulic coupling 2 comprises housing parts 8, 9 and a partition wall 10 with at least one opening 11, which is closable by means of a valve 12. The partition wall 10 divides a media-containing space in the hydraulic coupling 2 in a storage chamber 13 and a drive chamber 14. In the drive chamber 14 is arranged a friction disc 15, which is rotatably attached to a drive flange 16, which rests rotatably on the bearing pin 1a. The housing part 8 of the hydraulic coupling 2 is arranged rotatably by means of a bearing 17 on the drive flange 16. The bearing 17 is shielded from the medium present in the working chamber 14 by means of a seal 18. the valve 12 is attached to the partition wall 10 next to the drive flange 16 and the partition wall has at 19 a bore 20 which connects the working chamber 14 and the storage chamber 13. The housing part 9 has next to the opening 11 a spacer ring 21 consisting of magnetically non-conductive material, which is attached to pole shoes 9a, 9b. The drive unit 3 comprises a V-belt pulley 22 with a sleeve-like extension 23, which forms a pole shoe, a spacer ring 24 consisting of magnetically non-conductive material, a pole shoe 25 and a fastening flange 28 consisting of structural parts 26, 27, which are rotatably connected together. Between the pole shoes 9a, 9b, to which the valve 12 belongs, and the pole shoes 23, 24, which belong to the electromagnetic coil 6, there is an air gap 30. An axial displacement of the hydraulic coupling 2 and the drive element 3 is prevented by means of a existing, screw-on securing device 29 at the end of the shaft 1.
Det med U-formig tvärsektion utformade cirkelringformiga hus- et 5 till den elektromagnetiska spolen 6 pekar med sina skänklar i riktning mot distansringen 24 och är anordnat mellan den hylsformiga förlängningen 24 av kilremskivan 22 och den hylsformiga polskon 25.The circular ring-shaped housing 5 of the electromagnetic coil 6 formed with a U-shaped cross-section points with its legs in the direction of the spacer ring 24 and is arranged between the sleeve-shaped extension 24 of the V-belt pulley 22 and the sleeve-shaped pole shoe 25.
Den visade hydrauliska kopplingen med fyllnadsnivåreglering omfattar ett för temperaturen hos ett karaktäristiskt ställe hos förbränningsmotorn känsligt organ för reglering av den elektromagne- tiska spolen 6. Detta organ kan särskilt utgöras av en termokontakt, som antingen är anordnad i kylmedelkretsloppet eller smörjmedelskrets- loppet i förbränningsmotorn beroende på om motorn är kyld medelst kyl- vätska eller luft.The hydraulic coupling with filling level control shown comprises a means for controlling the temperature of a characteristic point of the internal combustion engine for regulating the electromagnetic coil 6. This means may in particular consist of a thermal contact, which is arranged either in the coolant circuit or the lubricant circuit dependent on the internal combustion engine. on whether the engine has been cooled by coolant or air.
Av fig 2 framgår att ventilen 12 består av formdelar 12a och en ringformig skiva 31, som är tillverkad av magnetiskt ledande material och fäst vid formdelarna 12a intill öppningen 11.From Fig. 2 it can be seen that the valve 12 consists of mold parts 12a and an annular disc 31, which is made of magnetically conductive material and attached to the mold parts 12a next to the opening 11.
Vid igàngsättning av förbränningsmotorn är temperaturen vid det karaktäristiska stället lägre än ett förutbestämt gränsvärde och därmed är termokontakten öppen och den elektromagnetiska spolen genom- flytes icke av någon ström. De i mellanväggen 10 befintliga öppning- arna 11 är stängda av ventilen 12. Genom vridning av drivelementet 3 sätts via drivflänsen 16 friktionsskenan 15 och husdelen 8 i rota- tion. Under inverkan av centrifugalkraften vid rotationen av husdelen 8 pumpas visköst medium ur arbetskammaren genom borrningen 20 och in i förrådskammaren, varigenom arbetskammaren 14 töms och friktionsski- vans 15 drivrörelse icke längre kan överföras till husdelarna 8, 10.When starting the internal combustion engine, the temperature at the characteristic point is lower than a predetermined limit value and thus the thermal contact is open and the electromagnetic coil is not flowed through by any current. The openings 11 present in the partition wall 10 are closed by the valve 12. By rotating the drive element 3, the friction rail 15 and the housing part 8 are set in rotation via the drive flange 16. Under the influence of the centrifugal force during the rotation of the housing part 8, viscous medium is pumped out of the working chamber through the bore 20 and into the storage chamber, whereby the working chamber 14 is emptied and the driving movement of the friction disc 15 can no longer be transmitted to the housing parts 8, 10.
