Description
15 20 25 50 35 78020942-0 anordning enligt uppfinningen blir enklare och driftsšíkrare än nämnda tidigare I kända anordningar, bl a genom att endast magnethuset är försett med efterställ- nings organ . Device according to the invention becomes simpler and more reliable than the previously mentioned devices, among other things by the fact that only the magnetic housing is provided with resetting means.
Uppfinningen skall närmare beskrivas i anslutning till på bifogade ritning vi- sade utföringsexempel. Fig 1, 2 och 5 visar tre olika alternativ av en enligt uppfinningen utförd skivbroms i axialsnitt. Fig 4 visar skivbromsens ändyta (lika för alla tre alternativen). Fig 5 och 6 visar i axialsnitt två. olika efterställningsorgan utan respektive med justerskruv.The invention will be described in more detail in connection with exemplary embodiments shown in the accompanying drawing. Figs. 1, 2 and 5 show three different alternatives of a disc brake designed according to the invention in axial section. Fig. 4 shows the end surface of the disc brake (same for all three options). Figures 5 and 6 show in axial section two. different adjustment members without or with adjusting screw.
Skivbromsen, som fig 1, 2 och 5 visar olika utföranden av, är monterad på en elektromotor, vid vilken axeln betecknas med 1 och motorhöljet med 2. Bromsen är monterad på. motorns ena ände utanför motorfläkten 5. Bromsen irmehåller en magnet A bestående av magnethus 4, spole 5 och magnetankare 6. Magnetankaret 6 fungerar även som bromsskiva. Magneten A är upphängd på fyra hörnbultar 7 och är försedd med efterställningsorgan B som sitter på rör 8 inskjutna på bultarna 7.The disc brake, of which Figs. 1, 2 and 5 show different embodiments, is mounted on an electric motor, at which the shaft is denoted by 1 and the motor housing by 2. The brake is mounted on. one end of the motor outside the motor fan 5. The brake contains a magnet A consisting of magnetic housing 4, coil 5 and magnetic anchor 6. The magnetic anchor 6 also functions as a brake disc. The magnet A is suspended on four corner bolts 7 and is provided with adjusting means B which sit on tubes 8 inserted on the bolts 7.
På. hörnbultarna 7 är även en bromsskiva 9 och en ändplatta 10 axiellt och ra- diellt fixerade. Den axiella fixeringen sker medelst distlazxsrör 11 och efter-A ställningsorganens rör 8. .Genom bromsskivan 9, ändplattan 10 samt ett yttre cylindriskt plåthölje 27 uppnås en effektiv kapsling av bromsen utan igensätt- ning av motorrxsikylluftsintag 28.On. the corner bolts 7 are also a brake disc 9 and an end plate 10 axially and radially fixed. The axial fixation takes place by means of distlazx tubes 11 and tubes 8 of the post-A positioning means. Through the brake disc 9, the end plate 10 and an outer cylindrical plate housing 27, an effective encapsulation of the brake is achieved without clogging of the engine xcycle air intake 28.
På. motoraxeln 1 är monterad en roterande bromsskiva 17 med friktionskutsar 15 tillverkade av sintermaterial med stor slitstwka. När mametspolen 5 är ström- lös, trycker magnetsystemets ankare 6 friktionskutsarzxa 15 mot den fasta broms- skivan 9 genom ett-antal i ändplattan 10 anordnade tryckfjädrar 18, varvid mellan magnethusets polyta och ankaret 6 bildas ett magnetluftg-ap a. När magnetspolen 5 får ström, attraheras ankaret 6 och bromsverkan upphör. Ankaret 6 är upphängt på. bultarna 7, som hindrar ankaret 6 att rotera.On. the motor shaft 1 is mounted a rotating brake disc 17 with friction pusher 15 made of sintered material with high wear resistance. When the magnetic coil 5 is de-energized, the armature 6 of the magnetic system pushes the friction pusher shaft 15 against the fixed brake disc 9 through a number of compression springs 18 arranged in the end plate 10, forming a magnetic air gap a between the magnetic housing and the armature 6. current, the anchor 6 is attracted and the braking effect ceases. Anchor 6 is suspended on. the bolts 7, which prevent the armature 6 from rotating.
Efterställningsorganen B är stationärt anordnade på. magnethnset 4. De består av ett rör 8, ett koniskt lagersäte 12 och med en fjäder 15 förtryckta kulor 14, som låser magnethuset 4 i rörelseriktning mot friktionskutsarna 15, samt en medbringare 16, som med hjälp av skruvar 24- och distansrör 19 är sammankopplad med ankaret 6 (fig 5). Medbringarnas 16 uppgift är att efter gradvis nedslit- ning av friktionskutsarna 15 frikoppla kulornas 14 låsfunktion, varvid magneten A kontinuerligt förskjuts mot friktionskutsarna 15 motsvarande nedslitningens storlek. De detaljer som utsätts för relativt hög punktbelastning, nämligen kulorna. 14, röret 8 och lagersätet 12, är härdade. 10 15 20 25 50 7800942-0 Efterställningsorganets B fjäder 13, som förtrycker kulorna 14, är inbyggd i lagersätet 12. Därigenom uppnås att efterställningsorganet bildar en samman- hängande enhet, som vid översyn av bromsen lätt kan demonteras.The resetting means B are stationary mounted on. The magnetic housing 4. They consist of a tube 8, a conical bearing seat 12 and with a spring 15 pre-pressed balls 14, which lock the magnetic housing 4 in the direction of movement against the friction liners 15, and a carrier 16, which is connected by means of screws 24 and spacer tubes 19 with the anchor 6 (Fig. 5). The task of the carriers 16 is to disengage the locking function of the balls 14 after gradual wear of the friction liners 15, whereby the magnet A is continuously displaced towards the friction liners 15 corresponding to the size of the wear. The details that are exposed to a relatively high point load, namely the balls. 14, the tube 8 and the bearing seat 12, are cured. The spring 13 of the adjusting member B, which displaces the balls 14, is built into the bearing seat 12. Thereby it is achieved that the adjusting member forms a continuous unit, which can be easily disassembled when the brake is inspected.
Vid den i fig 1 visade utföringsfonuen är tryckfjädrar 20 monterade mellan ankaret 6 och magrxetlniset 4, varvid maximalt magnetluftgap a alltid erhålles då magneten A är strömlös, dvs efterställningsorganets B lagersäte 12 tryckas tillsammans med magnethuset 4 mot medbringaren 16. I detta läge är efterställ- ningsorganets B låsfunlction upphävd. 5 När magnetspolen 5 får ström, attraheras ankaret 6. Mag-maten A rör sig först, på grund av att tryckfjädrarna 20 är svagare än bromsfjädrarna 18, i riktning mot ankaret 6 tills lagersätet 12 träffar kulorna 14 och låsning inträder.In the embodiment shown in Fig. 1, compression springs 20 are mounted between the armature 6 and the magnet 4, the maximum magnetic air gap a always being obtained when the magnet A is de-energized, i.e. the bearing seat 12 of the resetting member B is pressed together with the magnetic housing 4 against the carrier 16. In this position locking function B is canceled. When the magnetic coil 5 receives current, the armature 6 is attracted. The stomach feed A first moves, due to the compression springs 20 being weaker than the brake springs 18, in the direction of the armature 6 until the bearing seat 12 hits the balls 14 and locking occurs.
Därefter rör sig ankaret 6 mot magnethxiset 4 resterande del av luftgapet a så. att frigång för friktionskutsama 15 erhålles och bromsverkan upphör.Thereafter, the armature 6 moves against the magnetic axis 4 remaining part of the air gap a so. that clearance for the friction liners 15 is obtained and the braking action ceases.
Genom de mellan magxethuset 4 och ankaret 6 anordnade fjädrarna 20 uppnås för det första att luftgapet inte kan bli noll när magneten A är spänningslös och tryckfjädern 18 borttagen, för det andra att magxeten A vid montering, demonte- ring eller byte av friktionskutsar 15 är axiellt förskjutbar i båda riktningarna och för det tredje att efterställning till felaktigt luftgap a på grund av vib- rationer eller slag då. magneten A är spänningslös förhindras.Through the springs 20 arranged between the magnet housing 4 and the armature 6, it is achieved firstly that the air gap cannot become zero when the magnet A is de-energized and the compression spring 18 is removed, secondly that the magnet A is axially mounted, disassembled or replaced. displaceable in both directions and thirdly that subtraction to incorrect air gap a due to vibrations or blows then. magnet A is de-energized prevented.
Vid den i fig' 2 visade utföringsformen är tryckfjädrar 21 monterade mellan änd- plattan 10 och magnethuset 4, varvid kulorna 14 i efterställningsorganen B är i låst läge och frikopplas av medbringarna 16 endast då luftgapet a. mellan magnethuset 4 och ankaret 6 på. grund av nedslitning av friktionslcutsarna 15 blivit större än det maximalt tillåtna. Härvid trycks magnethuset 4 av fjäd- rarna 21 i riktning mot ankaret 6 med nedslitningens storlek, dvs tills kulorna 14 åter kommer i ingrepp och axiell låsning av magnethuset inträder.In the embodiment shown in Fig. 2, compression springs 21 are mounted between the end plate 10 and the magnetic housing 4, the balls 14 in the recess means B being in the locked position and disengaged by the carriers 16 only when the air gap a. Between the magnetic housing 4 and the armature 6 is on. due to wear of the friction clutters 15 has become larger than the maximum allowed. In this case, the magnetic housing 4 is pushed by the springs 21 in the direction of the armature 6 with the size of the wear, ie until the balls 14 come into engagement again and axial locking of the magnetic housing occurs.
Vid den i fig 5 visade utföringsformen kommer fjädrarna 15, som normalt håller kuloma. 14 i ingrepp, att vid nedslitning av friktionskutsarna 15 trycka magnet- huset 4 i riktning mot ankaret 6 till det läge där kulorna 14 åter låser.In the embodiment shown in Fig. 5 come the springs 15, which normally hold the balls. 14 in engagement, to push the magnetic housing 4 in the direction of the armature 6 to the position where the balls 14 lock again when the friction liners 15 are worn down.
Gemensamt för de i fig 1, 2 och 5 visade alternativen är att nedslitningen av friktionskutsarna 15 automatiskt kompenseras så. att magnetluftgapet a hållas så gott som konstant.Common to the alternatives shown in Figs. 1, 2 and 5 is that the wear of the friction pusher 15 is automatically compensated in this way. that the magnetic air gap a is kept almost constant.
