Description
454 164 2 en effektiv förbindelse mellan bromsskivor och hjulskiva kan åstadkommas med förhållandevis enkla medel, varvid dessutom ocksa gummidelarna hos det gummifjädrande hjulet i hög grad skyddas mot värme. Därutöver astadkoms pa tillfredställande sätt att bromsringarna kan utvidga sig pa grund av uppvärmningen vid bromsning och ater dra ihop sig. Eftersom vidare broms- ringen anligger och är fäst vid hjulskivan blott vid sin radiella mitt, kan den ocksa utan spänning nyckelformigt deformera sig. 454 164 2 an effective connection between brake discs and wheel disc can be achieved by relatively simple means, whereby in addition also the rubber parts of the rubber spring wheel are to a large extent protected against heat. In addition, it is satisfactorily achieved that the brake rings can expand due to the heating during braking and contracting again. Furthermore, since the brake ring abuts and is attached to the wheel disc only at its radial center, it can also deform in a key-like manner without tension.
En utföringsform av uppfinningen visas som exempel pa de bifoga- de ritningarna, varvid, - fig. 1 visar ett hjul sett fran sidan med delvis urskuren bromsring och fig. 2 ett snitt utmed linjen lI-II i fig. 1.An embodiment of the invention is shown by way of example in the accompanying drawings, in which: Fig. 1 shows a wheel seen from the side with a partially cut-out brake ring and Fig. 2 a section along the line II-II in Fig. 1.
Enligt fig. 1 och 2 bestar ett rälsfordonshjul av ett nav 11 med hjulskiva 12 och hjulring 13, varvid förspända gummikroppar 14, som ger hjulet en viss elasticitet, är insatta mellan hjulskivan 12 och hjuiringen 13. En odelad bromsring 15 respektive 16 är anordnad pa vardera sidan om bromsski- van 13 och dessa är fästa vid hjulskivan med axelparallella skruvar 17.According to Figs. 1 and 2, a rail vehicle wheel consists of a hub 11 with wheel disc 12 and wheel ring 13, wherein prestressed rubber bodies 14, which give the wheel a certain elasticity, are inserted between the wheel disc 12 and the wheel ring 13. An integral brake ring 15 and 16, respectively, is arranged on each side of the brake disc 13 and these are attached to the wheel disc with axle-parallel screws 17.
Skruvarnas 17 skruvhuvuden och muttrar ligger därvid i fördjupningar 18 pa bromsringarna 15 och 16. Till varje skruv 17 hör ett hal i hjulskivan 12, i vilket en spännhylsa 19 är insatt. lnnerdiametern hos spännhylsorna 19 är större än skruvarnas 17 diameter, sa att skruvarna kan röra sig l radiell riktning i tillhörande spännhylsa 19. Spännhylsorna 19 skjuter omväxlande ut pa hjulskivans ena och andra sida, varvid en glidtärning 20 är anordnad pa detta utskjutande stycke. Glidtärningarna 20 har ungefär radiellt liggande glidytor 21, som med glidpassning ligger an mot motsvarande glidytor pa ansatser 22, vilka är anordnade pa bromsringarna 15 och 16. Dessa glidytor 21 överför bromskraften fran bromsringarna 15 och 16 pa hjulet. Om bromsarna blir varma vid bromsning ökas deras diameter, varvid glidytorna 21 och ansatserna 22 förskjuts i förhållande till glidytorna 21 pa glidtärningarna 20, varför inga spänningar uppstar i hjulskivan 12 eller bromsringarna 15 och 16.The screw heads and nuts of the screws 17 then lie in depressions 18 on the brake rings 15 and 16. Each screw 17 has a slide in the wheel disc 12, in which a clamping sleeve 19 is inserted. The inner diameter of the clamping sleeves 19 is larger than the diameter of the screws 17, so that the screws can move in a radial direction in the associated clamping sleeve 19. The clamping sleeves 19 project alternately on one and the other side of the wheel disc, a sliding dice 20 being arranged on this projecting piece. The sliding cubes 20 have approximately radially lying sliding surfaces 21, which with sliding fit abut against corresponding sliding surfaces on shoulders 22, which are arranged on the brake rings 15 and 16. These sliding surfaces 21 transmit the braking force from the brake rings 15 and 16 on the wheel. If the brakes become hot during braking, their diameter increases, whereby the sliding surfaces 21 and the shoulders 22 are displaced relative to the sliding surfaces 21 on the sliding cubes 20, so that no stresses arise in the wheel disc 12 or the brake rings 15 and 16.
Eftersom därvid ocksa skruvarna 17 förskjuts i radiell riktning, maste spelrummet mellan skruvarna 17 och spännhylsorna 19 förefinnas. Detta spelrum är pa känt sätt valt sa stort, att skruvarna inte ens vid kraftigaste uppvärmning kommer till anliggning mot spännhylsorna 19. När bromsringarna 15 och 16 ater svalnat, rör sig ansatserna 22 i förhallande till glidtärningarna 20 tillbaka till det ursprungliga läget. Eftersom bromsringarna 15 och 16 anligger blott vid sin radiella mitt mot hjulskivan l2,där de är fästa, kan de ocksa utan spänning deformeras nyckelformigt. 454 164 3 Eftersom för varje skruv en glidsten 20 ligger blott pa ena sidan av hjulet, ehuru dock omväxlande pa bada sidor för samtliga skruvar, kan det förekomma att skruvarna 17 vid olika uppvärmning av de bada bromsringarna 15 och 16 kommer att lägga sig snett. Om exempelvis bromsringen 15 blir varmare än bromsringen 16 kommer skruvhuvudet vid bromsringen 15 att ligga längre bort fran navet ll än muttern vid bromsringen 16. Denna skillnad kan emellertid skruven 17 utan vidare ta upp, varvid visserligen glidtärningen 20 vid bromsringen 16 rör sig nagot utat, vilket dock utan vidare är möjligt.Since the screws 17 are also displaced in the radial direction, the clearance between the screws 17 and the clamping sleeves 19 must be present. This clearance is chosen so large in a known manner that the screws do not come into contact with the clamping sleeves 19 even at the strongest heating. When the brake rings 15 and 16 have cooled down again, the shoulders 22 move in relation to the sliding cubes 20 back to the original position. Since the brake rings 15 and 16 abut only at their radial center against the wheel disc 12, where they are attached, they can also be key-shaped without tension. 454 164 3 Since for each screw a sliding stone 20 lies only on one side of the wheel, although alternately on both sides for all screws, it may happen that the screws 17 will lie obliquely at different heating of the two brake rings 15 and 16. If, for example, the brake ring 15 becomes hotter than the brake ring 16, the screw head at the brake ring 15 will be further away from the hub 11 than the nut at the brake ring 16. However, the screw 17 can easily absorb this difference, the sliding dice 20 at the brake ring 16 which, however, is readily possible.
Bromsringarna kan pa känt sätt pa baksidan vara försedda med kylflänsar som bildar kylluftkanaler eller inte ha nagra sadana.The brake rings can in a known manner be fitted on the back with cooling fins which form cooling air ducts or do not have any such.
Istället för att man har en spännhylsa 19, kan glidtärningen 20 ocksa vara utförd i ett stycke med hjulskivan 12, exempelvis i samma göt.Instead of having a clamping sleeve 19, the sliding cube 20 can also be made in one piece with the wheel disc 12, for example in the same ingot.
Principiellt kan ocksa glidtärningen 20 och ansatserna 22 växlas, sa att glidtärningen ligger pa bromsringarnas baksida medan ansatserna är anordna- de pa hjulskivan. Detta ändrar inte funktionen hos elementen. Man kan emellertid ocksa ha tva glidtärningar 20 för varje skruv J] pa ömse sidor om hjulskivan 12, varigenom de bada bromsringarna kan utvidga sig oberoende av varandra utan att skruvarna 17 förskjuts. I stället för spännhylsan 19 kan man ocksa ha rörstycken insatta i hjulskivan, exempelvis insvetsade. xIn principle, the sliding dice 20 and the shoulders 22 can also be shifted, so that the sliding dice lie on the back of the brake rings while the shoulders are arranged on the wheel disc. This does not change the function of the elements. However, it is also possible to have two sliding cubes 20 for each screw J] on either side of the wheel disc 12, whereby the two brake rings can expand independently of each other without the screws 17 being displaced. Instead of the clamping sleeve 19, it is also possible to have pipe sections inserted in the wheel disc, for example welded in. x
