Nostoteli Tämän keksinnön kohteena on nostoteli kuormaa kuljettavia ajoneuvoja varten, joka nostoteli käsittää teliak-5 selin, kaksi teliakselille kiertyvästi sovitettua keinuvi-pua, joiden ensimmäisiin päihin on tarkoitettu kiinnitettäväksi vieressä olevien telipyörien jousipakat ja toisiin päihin nostettavat/laskettavat telipyörät, ja voimasylin-terin, joka toisesta päästään on kiinnitetty kannattimeen 10 ja toisesta päästään kääntövarteen, joka on tarkoitettu vaikuttamaan keinuvipuihin telipyörien nostamiseksi/las-kemiseksi.The present invention relates to a lifting frame for load-carrying vehicles, which lifting frame comprises a bogie axle, two rocker arms rotatably mounted on a bogie axle, the first ends of which are intended for attaching spring packs of adjacent bogie wheels and bogie blades to be raised / lowered, and a power cylinder, which is attached at one end to a support 10 and at the other end to a pivot arm intended to act on the rocker arms for raising / lowering the bogie wheels.

Kuormaa kuljettavissa ajoneuvoissa nostotelien käyttäminen on hyvin yleistä vaihtelevien kuormitustilan-15 teiden hallitsemiseksi. Aluksi käytetyistä, melko monimutkaisista ja vaihtelevista järjestelyistä pyrittiin kehittämään yhtenäisempi rakenne. Tällöin päädyttiin nostote-liin, jossa sekä teliakseli että voimasylinteriä tukeva kannatin on kiinteästi kiinnitetty ajoneuvon pitkittäisiin 20 runkopalkkeihin kiinnitettäviin kiinnityspukkeihin. * Tällaisen aikaisemmin tunnetun nostotelin, jota on kuvattu mm. FI-kuulutusjulkaisussa 71098, epäkohtana on, että se soveltuu vain tietylle ajoneuvon runkoleveydelle ja lisäksi runkoleveyden valmistustoleranssi, joka voi 25 olla muutamia millimetrejä, aiheuttaa erityisiä ongelmia, sillä kiinnitysleveyden suhteen ei käytännössä ole juuri lainkaan pelivaraa. Nostotelin kiinnitysleveys määräytyy ensinnäkin kiinnityspukkien ja teliakselin välisestä kiinteästä liitoksesta ja toisaalta kiinnityspukkien ja 30 voimasylinterin kannattimen välisestä kiinteästä liitoksesta.In load-bearing vehicles, the use of lifting rollers is very common to control varying load conditions. Initially, the aim was to develop a more coherent structure from the rather complex and varied arrangements used. This resulted in a lifting line in which both the bogie axle and the support supporting the power cylinder are fixedly attached to the mounting brackets to be attached to the longitudinal frame beams of the vehicle. * Such a previously known lifting bogie, which is described e.g. In FI publication 71098, the disadvantage is that it is only suitable for a certain frame width of the vehicle and, in addition, the manufacturing tolerance of the frame width, which can be a few millimeters, causes special problems, as there is practically no room for maneuver width. The mounting width of the lifting frame is determined, firstly, by the fixed connection between the mounting brackets and the bogie shaft and, secondly, by the fixed connection between the mounting brackets and the power cylinder support 30.

Tämän keksinnön tarkoituksena on aikaansaada nostoteli, jolla edellä mainitut epäkohdat vältetään ja joka mahdollistaa nostotelin valmistamisen mahdollisimman käyt-35 tövalmiiksi siten, että se yksinkertaisin välinein ja vai- 2 79978 vatta voidaan kiinnittää ajoneuvon runkoon toimivaksi rakenteeksi. Tämä tarkoitus aikaansaadaan nostotelillä, jolle on tunnusomaista, että voimasylinteriä tukeva kannatin on sovitettu teliakselille, ja teliakseli on irrotettavasti 5 kiinnitetty kahteen, ajoneuvon pitkittäisiin runkopalkkei-hin sovitettavaan kiinnityspukkiin.The object of the present invention is to provide a lifting scaffold which avoids the above-mentioned drawbacks and which makes it possible to manufacture the lifting scaffold as ready for use as possible so that it can be attached to the vehicle body as a simple structure by means and simple means. This purpose is achieved by a lifting frame, which is characterized in that the support supporting the power cylinder is arranged on the bogie axle, and the bogie axle is detachably attached to two mounting brackets which can be fitted to the longitudinal frame beams of the vehicle.

Keksinnön mukaisen nostotelin perusajatuksena on, että se voidaan valmistaa periaatteessa täysin riippumatta siitä, mihin ajoneuvoon se tullaan asentamaan. Tämä toteu-10 tetaan helposti siten, että ajoneuvojen vaihtelevat runko-leveydet, so. pitkittäisten runkopalkkien väliset etäisyydet, yhdenmukaistetaan teliakselin irrotettavalla kiinnityksellä kiinnityspukkeihin. Nostotelin sopeuttaminen eri runkoleveyksille toteutetaan teliakselin antaman aksiaali-15 sen siirtymävaran avulla. Tällöin nostotelin osat voidaan valmistaa standardisoituina halutun kuormankanto- ja nos-tokyvyn mukaan. Näin ollen teliakselitiivistyskään ei aiheuta ajoneuvokohtaisia lisäongelmia. Huomattava etu on myös asennuksen helppous ja nopeus. Lisäksi sekä rungon 20 uiko- että sisäpuolelle tulevien kiinnityspukkien käyttö on mahdollista.The basic idea of the lifting scaffold according to the invention is that it can in principle be manufactured completely regardless of the vehicle in which it is to be installed. This is easily accomplished by varying the frame widths of the vehicles, i. the distances between the longitudinal frame beams are harmonized by the detachable attachment of the bogie axle to the mounting brackets. The adjustment of the lifting bogie to different frame widths is carried out by means of the axial-15 clearance provided by the bogie shaft. In this case, the parts of the lifting bogie can be manufactured standardized according to the desired load-bearing and lifting capacity. Therefore, even the bogie shaft seal does not cause additional vehicle-specific problems. Another significant advantage is the ease and speed of installation. In addition, the use of mounting brackets on both the outside and inside of the body 20 is possible.

Keksintöä selitetään lähemmin esimerkinomaisesti seuraavassa viitaten oheiseen piirustukseen, jossa kuvio 1 esittää ajoneuvon pitkittäisiin runkopalk-25 keihin sovitettuja nostotelin kiinnityspukkeja, kuvio 2 esittää varsinaista nostoyksikköä, ja kuvio 3 esittää nostoteliä ajoneuvoon asennettuna. Kuviossa 1 on esitetty kuormaa kuljettavan ajoneuvon pitkittäisten runkopalkkien 1, 2 sisäpuolelle sovitetut 30 erilliset kiinnityspukit 3. Kiinnityspukkien alapäihin on muodostettu puolisylinterimäiset avarrukset, joihin nosto-telin teliakseli 7 on tarkoitettu asennettavaksi. Lisäksi kiinnityspukeissa on rungon sisäpuolelle suuntautuvat tapit 4, jotka on tarkoitettu asettumaan kuviossa 2 esitetyn, 35 voimasylinteriä 6 tukevan kannattimen 5 kahdessa varressa 3 79978 5’ oleviin syvennyksiin 5a. Tämän järjestelyn avulla voima-sylinterin asema lukitaan ajoneuvon runkopalkkien suhteen. Voimasylinterin 6 kannattimen 5 varret 5'on asennettu te-liakselille 7 kitkasovituksella, joka lähinnä estää kan-5 nattimen aksiaalisuunnassa mahdollisesti tapahtuvaa liukumista .The invention will be described in more detail by way of example below with reference to the accompanying drawing, in which Figure 1 shows lifting rack mounting brackets fitted to the longitudinal frame beams of a vehicle, Figure 2 shows the actual lifting unit, and Figure 3 shows a lifting rack mounted on a vehicle. Figure 1 shows 30 separate mounting brackets 3 arranged inside the longitudinal frame beams 1, 2 of a load-carrying vehicle. Semi-cylindrical recesses are formed in the lower ends of the mounting brackets, on which the bogie shaft 7 of the lifting bogie is intended to be mounted. In addition, the mounting brackets have pins 4 extending inside the body, which are intended to fit into the recesses 5a in the two arms 3 79978 5 'of the support 5 supporting the power cylinder 6 shown in Fig. 2. With this arrangement, the position of the force cylinder is locked with respect to the frame beams of the vehicle. The arms 5 'of the support 5 of the power cylinder 6 are mounted on the roller shaft 7 with a friction fit, which mainly prevents any possible sliding of the support 5 in the axial direction.

Kuviossa 2 on esitetty varsinainen nostoyksikkö. Tämä käsittää kaksi teliakselin 7 päihin kiertyvästi sovitettua keinuvipua 8, joiden ensimmäisiin päihin 8a on tar-10 koitettu kiinnitettäväksi vieressä olevien telipyörien jousipakat ja toisiin päihin 8b nostettavat/laskettavat telipyörät. Lisäksi siinä on nosto/laskuvaikutuksen aikaansaava sovitelma, joka käsittää voimasylinterin 6, joka toisesta päästään on laakeroitu kannattimen 5 kahteen 15 varteen 5’, jotka on sovitettu teliakselile 7 aikaisemmin mainitulla tavalla. Voimasylinterin toinen pää on laakeroitu teliakselille kiertyvästi asennettuun kääntövarteen 9, jonka haarat 10 vaikuttavat keinuvipujen 8 ensimmäisiin päihin 8a, näiden liikuttamiseksi siten, että keinuvipujen 20 toisiin päihin 8b asennetut telipyörät voidaan nostaa, laskea tai lukita paikalleen. Voimasylinterinä käytetään edullisesti hydraulisylinteriä. Voimasylinterin 6 kiinnitys on edullisesti aseteltavissa sekä kannattimen 5 varsien 5' että kääntövarren 9 kohdalta, jolloin jousipakan kuoleen-25 tumisesta johtuva telipyörien yläaseman vajoaminen voidaan kompensoida muuttamalla kääntövarren 9 kulma-asentoa. Nos-totelin nostokorkeutta voidaan edullisesti säätää esimerkiksi kääntövarren 9 haaroihin 10 muodostetuilla aseteltavilla ulokkeilla 11, jotka asettuvat keinuvipuihin muodos-30 tettuihin vastepintoihin 12. Tässä ainoastaan esimerkkinä kuvatussa ratkaisussa ulokkeet ovat pyöristetyillä pälliä varustettuja, kierrettäviä tappeja ja vastepinnat näihin muodoltaan sopivia kaarevapintaisia hyllyjä.Figure 2 shows the actual lifting unit. This comprises two rocker arms 8 rotatably arranged at the ends of the bogie axle 7, to the first ends 8a of which spring packs of adjacent bogie wheels are intended to be attached and to the second ends 8b to be raised / lowered bogie wheels. In addition, it has a lifting / lowering arrangement comprising a power cylinder 6 mounted at one end on two arms 5 'of the support 5, which are arranged on the bogie shaft 7 in the manner previously mentioned. The other end of the power cylinder is mounted on a pivot arm 9 rotatably mounted on the bogie shaft, the arms 10 of which act on the first ends 8a of the rocker arms 8 to move them so that the bogie wheels mounted on the other ends 8b of the rocker arms 20 can be raised, lowered or locked. The hydraulic cylinder used is preferably a hydraulic cylinder. The attachment of the power cylinder 6 is preferably adjustable both at the arms 5 'of the support 5 and at the pivot arm 9, whereby the lowering of the bogie wheels due to the death of the spring pack can be compensated by changing the angular position of the pivot arm 9. The lifting height of the lifting bar can advantageously be adjusted, for example, by adjustable projections 11 formed in the arms 10 of the pivot arm 9, which abut the abutment surfaces 12 formed on the rocker arms. In the solution described here only by way of example, the projections are rounded pins with rotating pins and abutment surfaces.

Kuviossa 3 on esitetty ajoneuvoon asennettu nosto-35 teli. Kiinnityspukit 3 on esimerkiksi kiinnitetty ajoneuvon 4 79978 pitkittäisiin runkopalkkeihin pulttiliitoksilla. Teliakseli 7 siihen sovitettuine, edellä kuvattuine rakenteineen, on ripustettu kiinnityspukkeihin kahden U-muotoisen elimen 13 ja näihin sovitetun teliakselia vasten puristuvien tu-5 kikappaleiden 14 avulla, esimerkiksi tavanomaisilla mutteri-ruuviliitoksilla. Kiinnityspukkien välinen etäisyys L voi vaihdella tappi-syvennys-sovituksen 4, 5a ja kiinni-tyspukkien 3 ja teliakselin 7 välisen, aksiaalista säätö-varaa antavan kitkaliitoksen ansiosta, jolloin keksinnön 10 mukainen nostoteli on sovitettavissa eri runkoleveyksisiin ajoneuvoihin. Tämä on tietysti myös toteutettavissa esimerkiksi pidentämällä kiinnityspukkien 3 runkopalkkeihin 1, 2 kiinnitettävää haaraa tai muulla vastaavalla tavalla.Figure 3 shows a lifting bogie mounted on a vehicle. The mounting brackets 3 are, for example, fastened to the longitudinal frame beams of the vehicle 4 79978 by means of bolted joints. The bogie shaft 7 with the structures described above, described above, is suspended from the mounting brackets by means of two U-shaped members 13 and support pieces 14 pressed against the bogie axle, for example by means of conventional nut-screw connections. The distance L between the mounting brackets can vary due to the frictional connection between the pin-recess arrangement 4, 5a and the mounting brackets 3 and the bogie shaft 7, which provides axial adjustment space, whereby the lifting roller according to the invention can be adapted to vehicles of different frame widths. Of course, this can also be achieved, for example, by extending the branch to be fastened to the frame beams 1, 2 of the fastening brackets 3 or in another similar manner.

Piirustus ja siihen liittyvä selitysosa on vain 15 tarkoitettu havainnollistamaan keksinnön ajatusta. On selvä, että yksityiskohdat, kuten esimerkiksi voimasylinterin tuenta ja aseteltavuus, kääntövarren toiminnan säätäminen, teliakselin ripustus, kiinnityspukkien rakenne jne. voivat vaihdella oheisten patenttivaatimusten asettamissa puit-20 teissä.The drawing and the accompanying explanatory part are only intended to illustrate the idea of the invention. It is clear that the details, such as the support and adjustability of the power cylinder, the adjustment of the operation of the pivot arm, the suspension of the bogie axle, the structure of the mounting brackets, etc., may vary within the framework set by the appended claims.
