Description
455 186 duglighet. För det andra förhindras ocksa en skada pa cylinderns innervägg genom de mellan fjäderdelarna anordnade tryckplattorna. Och dessutom kan det vid förskjutning av kolven inte byggas upp nagot tryck vid de pa ömse sidor om tryckplattorna liggande kamrarna, vilket skulle kunna inkrâkta pa cylinderns funktion. 455 186 ability. Secondly, damage to the inner wall of the cylinder is also prevented by the pressure plates arranged between the spring parts. In addition, when the piston is displaced, no pressure can build up at the chambers on either side of the pressure plates, which could interfere with the function of the cylinder.
I figuren framställs ett exempel pa en utföringsform av uppfin- ningen. Cylindern ll âr omsluten av locken 12 och 13 pa sina bada sidor. Vid locket 12 är en flâns 15 anordnad, under mellankoppling av ett centrerings- gummi 14, med vilken cylindern ll kan anbringas vid boggin eller vagnsra- men. I locket 12 är dessutom en inloppsöppning 16 anordnad för den cylindern manövrerande fluiden. Locket 13 har ett avtâtat hal för kolvstangen 17, vilken a sin sida via ett centreringsgummí 18 uppbär en flâns 19, vid vilken magnetskenbromsen fastsätts. Dessutom är i locket 13 ocksa ett avluftnings- hal 20 anordnat.The figure shows an example of an embodiment of the invention. The cylinder is enclosed by lids 12 and 13 on both sides. At the cover 12 a flange 15 is arranged, during intermediate connection of a centering rubber 14, with which the cylinder 11 can be fitted to the bogie or the carriage frame. In addition, an inlet opening 16 is provided in the lid 12 for the cylinder operating the cylinder. The lid 13 has a sealed hall for the piston rod 17, which in turn supports a flange 19 via a centering rubber 18, to which the magnetic rail brake is attached. In addition, a venting hall 20 is also arranged in the lid 13.
Vidare har locket 13, pa sin mot flänsen 19 vända sida 21 en pa denna sida 21 anordnad taktypliknande gummiring 22.Furthermore, the lid 13, on its side 21 facing the flange 19, has a roof-type rubber ring 22 arranged on this side 21.
Vid andra änden av kolvstangen 17 är en i cylindern ll tätt glidande kolv 23 anordnad, vilken tillsammans med locket 12 bildar en med inloppsöppningen 16 förbunden tryckkammare 24. Kolvstangen 17 är förlängd förbi kolven 23 med stycket 25, med vilket kolvstangen 17, i det i figuren framställda vilolëget, ligger i ett hal 26 i locket 12. I cylinderrummet 27 är en avftva delar 28 och 29 bestående fjäder lagrad, varvid en tryckplatta 30 är förskjutbart lagrad pa kolvstangen mellan delarna 28, 29. Tryckplattans 30 ytterdiameter är mindre än cylinderns ll innerdiameter med stycket 31, varigenom de pa bada sidor om tryckplattan 30 liggande kamrarna 27 är förbundna med varandra. Fjâderdelen 28 anligger med sin ena sida mot kolven 23 och med sin andra sida mot tryckplattans 30 ena sida och fjäderdelen 29 anlígger mot tryckplattans 30 andra sida och mot cylinderns ll undre lock 13.At the other end of the piston rod 17 a sliding piston 23 tightly arranged in the cylinder 11 is arranged, which together with the lid 12 forms a pressure chamber 24 connected to the inlet opening 16. The piston rod 17 is extended past the piston 23 with the piece 25, with which the piston rod 17 The resting position produced in the figure is located in a hall 26 in the lid 12. In the cylinder space 27 a spring consisting of two parts 28 and 29 is mounted, a pressure plate 30 being slidably mounted on the piston rod between the parts 28, 29. The outer diameter of the pressure plate 30 is smaller inner diameter with the piece 31, whereby the chambers 27 lying on both sides of the pressure plate 30 are connected to each other. The spring part 28 abuts with one side against the piston 23 and with its other side against one side of the pressure plate 30 and the spring part 29 abuts against the other side of the pressure plate 30 and against the lower lid 13 of the cylinder 11.
Bada fjâderdelarna 28 och 29 har ungefär lika karakteristik och ungefär lika längd.Both spring parts 28 and 29 have approximately the same characteristics and approximately the same length.
Cylindern enligt uppfinningen fungerar som sa, att i det visa_de viloläget dras den vid kolvstangen 17 fastsatta flänsen 19 mot gummiringen av fjädern 28, 29, varigenom kammaren 32 avtätas vid kolvstangena 17 uttrâdesöppning i cylinderlocket 13 mot yttre inverkan av vatten smuts etc.The cylinder according to the invention functions as such, that in the shown rest position the flange 19 attached to the piston rod 17 is pulled against the rubber ring by the spring 28, 29, whereby the chamber 32 is sealed at the piston rods 17 outlet opening in the cylinder cover 13 against external action of water dirt etc.
Genom centreringsgummit lB blir snedheter i flänsen 19 gentemot gummi- ringen 22 säkert utjämnade, sa att avtätningen är säkert garanterad.Through the centering rubber 1B, inclinations in the flange 19 relative to the rubber ring 22 are securely leveled, so that the sealing is securely guaranteed.
Skall nu magnetskenbromsen som är fastsatt vid flänsen 19 455 186 sänkas, sa leds tryck in i tryckkammaren 24 via inloppsöppningen 16, varigenom kolven 23 förskjuts i riktning mot locket 13. Därvid trycks de bada fjäderdelarna 28, 29 samman, varvid samtidigt tryckplattan 30 pâ kolvstângen 17 förskjuts. Närvarande luft i den vid kolven 23 liggande kammaren 27 trycks genom öppningen 31 vid tryckplattan 3D in l den andra kammaren 27 och dârifran ut i det fria genom avluftningsöppningen 20. F örskjutningen av kolven 23 pagar så länge, tills fjäderdelarnas 28, 29 lindningar ligger mot varandra. l detta läge ligger magnetskenbromsen pa skenan och bromsar.If the magnetic rail brake attached to the flange 19 455 186 is to be lowered, then pressure is led into the pressure chamber 24 via the inlet opening 16, whereby the piston 23 is displaced in the direction of the lid 13. The two spring parts 28, 29 are pressed together, the pressure plate 30 on the piston rod 17 is shifted. Air present in the chamber 27 adjacent the piston 23 is forced through the opening 31 at the pressure plate 3D into the second chamber 27 and thence out into the open through the vent opening 20. The displacement of the piston 23 continues until the windings of the spring parts 28, 29 lie against each other. In this position, the magnetic rail brake is on the rail and brakes.
Skall magnetskenbromsen äter lyftas, blir trycket i fluiden i tryckkammaren 24 avlett genom öppningen 16, så att kolven 23 av fjädrarna 28, 29 äter förskjuts i riktning mot locket 12, tills den har kommit till det visade viloläget. Därvid har stycket 25 pa kolvstangen 17 inskjutits i öppningen 26 i locket 12, varigenom kolvstangen 17 och kolven 23 är säkrade gentemot sidostötar. Under kolvens 23 atergängsrörelse har luft äter insugits i kammaren 27 genom öppningen 20, sa att denna kammare förblir tryckfri.If the magnetic rail brake is to be lifted, the pressure in the fluid in the pressure chamber 24 is diverted through the opening 16, so that the piston 23 of the springs 28, 29 eats is displaced in the direction of the cover 12, until it has reached the resting position shown. Thereby, the piece 25 of the piston rod 17 has been inserted into the opening 26 in the lid 12, whereby the piston rod 17 and the piston 23 are secured against side impacts. During the return movement of the piston 23, air has been sucked into the chamber 27 through the opening 20, so that this chamber remains pressure-free.
Vid flânsens 19 anslag mot gummiringen 22 åstadkommer denna ring en dämpning av anslagsstöten och samtidigt avtätas kammaren 32 kring kolv- stången, så att ingen smuts kan trånga in där.At the abutment of the flange 19 against the rubber ring 22, this ring provides a damping of the abutment shock and at the same time the chamber 32 around the piston rod is sealed, so that no dirt can penetrate there.
Tryckplattan kan också styras av cylinderns innervëgg, varvid en öppning lämnas mellan kolvstängen och tryckplattan, genom vilken tryckut- jâmningen kan äga rum.The pressure plate can also be guided by the inner wall of the cylinder, leaving an opening between the piston rod and the pressure plate, through which the pressure equalization can take place.
Gummiríngen 22 kan också bestå av andra elastiska material, som t.ex. plast och kan ocksa ha andra tvärsnittsformer.The rubber ring 22 may also consist of other elastic materials, such as plastic and may also have other cross-sectional shapes.
Man kan också ge fjäder-delarna skilda karakteristiker, vilket t.ex. i leder till skilda hastigheter vid lyftning av magnetskenbromsen.You can also give the spring parts different characteristics, which e.g. i leads to different speeds when lifting the magnetic rail brake.
