AJONEUVON, KUTEN KUORMA-AUTON JA PERÄVAUNUN VÄLINEN SÄHKÖ- JA PAINEILMAKYTKIN - EL- OCH TRYCKLUFTSKOPPLING FÖR FORDON, SÄSOM MELLAN LASTBIL OCH SLÄPVAGNELECTRICAL AND COMPRESSED AIR SWITCH BETWEEN VEHICLE SUCH AS TRUCK AND TRAILER - EL- OCH TRYCKLUFTSKOPPLING FOR FORDON, SÄSOM MELLAN LASTBIL OCH SLÄPVAGN

Tämän keksinnön kohteena on ajoneuvon, kuten kuorma-auton ja perävaunun välinen sähkö- ja paineilmakytkin, joka muodostuu naaraspuolisesta sähköpistorasiasta, johon on työnnettävissä urospuolinen pistoke, jonka paikallaanpysyminen on varmistettu pistorasian kannessa olevan varmistuskynnen avulla, ja yksi tai useampiletkuisesta paineilmakotelosta, johon paine-ilmaletkut on liitettävissä ja lukittavissa kiinni.The present invention relates to an electric and compressed air switch between a vehicle, such as a truck and a trailer, consisting of a female electrical socket into which a male plug can be inserted, secured in place by a securing claw on the socket cover, and one or more compressed air hoses. can be attached and locked.

Nykyisin, kun perävaunu irrotetaan kuorma-autosta, on kuorma-auton ja perävaunun väliset sähkö- ja paineilmaletkut irrotettava käsin. Tällöin on kuljettajan mentävä kuorma-auton ja perävaunun väliin. Joissakin tilanteissa tämä saattaa olla hankalaa ja turhaa aikaa vievää.Today, when a trailer is uncoupled from a truck, the electric and compressed air hoses between the truck and the trailer must be removed manually. In this case, the driver must go between the truck and the trailer. In some situations, this can be cumbersome and unnecessarily time consuming.

Tämän keksinnön tarkoituksena on poistaa edellä esitetyt epäkohdat. Keksinnön mukaiselle sähkö- ja paineilmakytkimelle on tunnusomaista se, että kytkimeen kuuluu painesylinteri, jonka avulla sekä pistoke että painei1ma 1 etkut on irrotettavissa pistorasiasta ja paineilmakotelosta, kun perävaunu kytketään irti. Keksinnön avulla voidaan nopeasti ja yksinkertaisesti nappia painamalla irrottaa pistoke ja paineilmaletkut samanaikaisesti, kun perävaunua kiinnipitävä kytkinpultti myös avataan painesylinterin avulla. Nämä toimenpiteet nopeuttavat huomattavasti perävaunun irrottamista kuorma-autosta ja lisäävät turvallisuutta, koska kuorma-auton ja perävaunun väliin ei tarvitse mennä.The object of the present invention is to eliminate the above drawbacks. The electric and compressed air switch according to the invention is characterized in that the switch comprises a pressure cylinder by means of which both the plug and the pressurized front can be detached from the socket and the compressed air housing when the trailer is disconnected. By means of the invention, the plug and the compressed air hoses can be removed quickly and simply by pressing a button at the same time as the clutch bolt holding the trailer is also opened by means of a pressure cylinder. These measures significantly speed up the uncoupling of the trailer from the truck and increase safety by eliminating the need to go between the truck and the trailer.

Keksinnön eräälle edulliselle sovellutusmuodolle on tunnusomaista se, että pistoketta ympäröi pistokkeen päällä liikkuva hylsy, johon painesylinterin voima vaikuttaa siten, että hylsy nostaa ensin kannen ja siinä olevan kynnen irti pistokkeesta ennenkuin varsinainen pistokkeen irrotusliike pääsee tapahtumaan. Näinollen saadaan yhdellä ja samalla painesylinterin liikkeellä sekä varmistus auki että pistoke irti.A preferred embodiment of the invention is characterized in that the plug is surrounded by a sleeve movable on top of the plug, which is acted upon by the pressure cylinder so that the sleeve first lifts the lid and the nail therein off the plug before the actual plug removal takes place. In this way, both the lock open and the plug can be removed with one and the same movement of the pressure cylinder.

7842578425

Keksinnön eräälle toiselle sovellutusmuodol1 e on tunnusomaista se, että hylsyssä on säteettäiset ulkonevat korvat, joihin painesylinterin männänvarren päässä oleva haarukkamai-nen elin työntövoimansa johdosta vaikuttaa. Tämä on yksinkertainen ja toimintavarma ratkaisu, jolla edellä esitetyt irro-tusliikkeet saadaan aikaiseksi.Another embodiment of the invention is characterized in that the sleeve has radial projecting ears which are affected by a fork-like member at the end of the piston rod of the pressure cylinder due to its thrust. This is a simple and reliable solution that achieves the release movements described above.

Keksinnön eräälle edulliselle sovellutusmuodolle on vielä tunnusomaista se, että painesylinterin männänvarsi on yhdistetty paineilmakotelossa olevaan sinänsä tunnettuun paine-ilmaletkujen irrotusmekanismiin siten, että sekä pistoke että painei1 ma1 etkut irtoavat samalla painesylinterin irrotusliik-keellä. Koska sekä pistoke että paineilmaletkut voivat olla vierekkäin, saadaan näinollen yhdellä ja samalla painesylin-terillä ja yhdellä irrotus1iikkee11ä kaikki kuorma-autoa ja perävaunua yhdistävät sähkö- ja paineilmaletkut irti.A further preferred embodiment of the invention is characterized in that the piston rod of the pressure cylinder is connected to a known air release mechanism for compressed air hoses in the compressed air housing, so that both the plug and the pressure front are released by the same release movement of the pressure cylinder. Since both the plug and the compressed air hoses can be side by side, all the electric and compressed air hoses connecting the truck and the trailer can thus be disconnected with one and the same pressure cylinder and one removal movement.

Keksintöä selostetaan seuraavassa esimerkin avulla viittaamalla oheisiin piirustuksiin, joissaThe invention will now be described, by way of example, with reference to the accompanying drawings, in which

Kuvio 1 esittää kuorma-auton ja perävaunun välistä kytkinkoh-taa .Figure 1 shows the coupling point between the truck and the trailer.

Kuvio 2 esittää sähkö- ja ilmapaineletkujen kytkintä ylhäältä katsottuna.Figure 2 shows a top view of the switch for electric and air pressure hoses.

Kuvio 3 esittää samaa kuin kuvio 2, mutta pistokkeen ja ilma-letkujen irrotus on osittain alkanut.Figure 3 shows the same as Figure 2, but the removal of the plug and air hoses has partially begun.

Kuvio 4 esittää kuviosta 2 nuolen 4 suunnassa katsottuna kytkintä .Figure 4 shows the view of Figure 2 in the direction of arrow 4 of the switch.

Kuorma-auton 1 ja perävaunun välinen sähkö- ja paineilmakyt-kin muodostuu naaraspuolisesta sähköpistorasias ta 2, johon on työnnetty urospuolinen pistoke 3, jonka paika 11aanpysyminen on varmistettu pistorasian 2 kannessa 4 olevan varmistuskyn-nen 5 avulla. Kytkin muodostuu myös kaksi1 etkuisesta paineli makote1osta 6, johon paineilmaletkut 7, 8 on liitettävissä 3 78425 ja lukittavissa kiinni. Kytkimeen kuuluu painesylinteri, jonka avulla sekä pistoke että paineilmaletkut on irrotettavissa pistorasiasta ja paineilmakotelosta, kun perävaunu kytketään irti. Kytkimeen kuuluu painesylinteri 9, jonka avulla sekä pistoke 3 että paineilmaletkut 7, 8 on irrotettavissa pistorasiasta 2 ja paineilmakotelosta 6, kun perävaunu kytketään irti. Pistoketta 3 ympäröi pistokkeen päällä liikkuva hylsy 10, johon painesylinterin voima vaikuttaa, kuten kuviossa 3 on esitetty, siten, että hylsy 10 nostaa ensin kannen 4 ja siinä olevan kynnen 5 irti pistokkeesta 3 ennenkuin varsinainen pistokkeen irrotusliike pääsee tapahtumaan nuolen 11 osoittamalla tavalla. Hylsyssä 10 on säteettäiset ulkonevat korvat 12, joihin painesylinterin männänvarren 13 päässä oleva haarukkamainen elin 14 työntövoimansa johdosta vaikuttaa. Painesylinterin 9 männänvarsi 13 on poikittaisella tapilla 15 yhdistetty paineilmakotelossa 6 olevaan sinänsä tunnettuun paineilmaletkujen 7, 8 irrotusmekanismiin siten, että sekä pistoke 3 että paineilmaletkut 7, 8 irtoavat samalla painesylinterin 9 irrotusliikkeellä.The electric and compressed air switch between the truck 1 and the trailer consists of a female electrical socket 2, into which a male plug 3 is inserted, the position of which is ensured by means of a securing pin 5 in the cover 4 of the socket 2. The coupling also consists of two front pressure recesses 6, to which the compressed air hoses 7, 8 can be connected 3 78425 and locked. The clutch includes a pressure cylinder that allows both the plug and the compressed air hoses to be removed from the outlet and the compressed air housing when the trailer is uncoupled. The coupling includes a pressure cylinder 9, by means of which both the plug 3 and the compressed air hoses 7, 8 can be disconnected from the socket 2 and the compressed air housing 6 when the trailer is disconnected. The plug 3 is surrounded by rolling on the plug socket 10 to which the force of the pressure cylinder control, as shown in Figure 3, so that the sleeve 10 to raise the first cover 4 and in the nail 5 from the plug 3, before the actual plug release movement can take place denoted by the arrow 11 in. The sleeve 10 has radial projecting lugs 12 which are acted upon by a fork-like member 14 at the end of the piston rod 13 of the pressure cylinder due to its thrust. The piston rod 13 of the pressure cylinder 9 is connected by a transverse pin 15 to a known mechanism for removing the compressed air hoses 7, 8 in the compressed air housing 6, so that both the plug 3 and the compressed air hoses 7, 8 are released by the same release movement of the pressure cylinder 9.
