'_ , ,. 7907786-3 att fästorganen befinner sig inne i bromsen, varigenom ytterdimensionen ej ändras . Genom direkt infästning av den rektangulärt böjda änden pä hällfjädem, tjänar en del av fjädern samtidigt som ett stöd vilket innebär materialvinst . '_,,. 7907786-3 that the fastening means are located inside the brake, whereby the outer dimension does not change. By directly attaching the rectangularly bent end to the spring, part of the spring also serves as a support, which means material gain.
Genom att forma hällfjädem sä att en borrning med en slits bildas i broms- skiveaxelns riktning i den rektangulärt böjda änden, vilken borrning hakar pä en bult med ett huvud och fäst vid urtagningens vägg, erhålles en infäst- ning som medger manuell montering och demontering av fjädem utan special- verktyg. Efter monteringen är hällfjädern säkrad av fjäderändarna som stöder mot bromsbackarna.By forming the pouring spring so that a bore with a slot is formed in the direction of the brake disc shaft in the rectangularly bent end, which bore hooks onto a bolt with a head and fastened to the wall of the recess, a fastening is obtained which allows manual mounting and disassembly of spring without special tools. After mounting, the hob spring is secured by the spring ends that support the brake shoes.
Om avständet mellan bulthuvudet och bromsbygelns vägg väljs sä att det ' exakt motsvarar tj ockleken av hällfjädems fästände och om hällfjädern stöder mot bromsbygeln utanför fästet och hälls pä plats i bromsbygeln i bromsskivans omkretsriktning av urtagningens väggar, sä hälls den orörligt fast i bromsbygeln även om fjädern skulle gä av, i vilket fall ett ensidigt tryck skulle uppkomma pä hällorganet.If the distance between the bolt head and the wall of the brake caliper is chosen so that it 'exactly corresponds to the thickness of the retaining spring mounting end and if the retaining spring abuts the brake caliper outside the bracket and is held in place in the brake caliper in the circumferential direction of the brake disc, would go off, in which case a one-sided pressure would arise on the pouring means.
Genom att utforma hällfjädern sä att den bestär av tvä olika bladfjädrar vars fäständar ligger likformigt pä varandra, medan deras andra ändar stöder pä var sin bromsback , uppnäs att päverknings punkterna för bladfj ädrama ligger i rät linje med fästpunkten pä bromsbygeln, varigenom nägot stjälpningsmoment mot fästpunkten ej uppstär ens vid fjäderbrott.By designing the pouring spring so that it consists of two different leaf springs whose fastening ends lie uniformly on each other, while their other ends rest on their respective brake jaws, it is achieved that the points of impact of the leaf springs are in line with the fastening point on the brake caliper. does not occur even in spring breakage.
Genom att anordna bladfjädern sä att den stöder mot bromsbacken intill bygeln med fjädrande tungor som med sina fria ändar sträcker sig i broms- skivans omkretsriktning och verkar pä bromsbacken, uppnäs att tryckkraften blir mjukare och mera likformigt fördelad pä bromsbacken. Fjäderns mjukhet kan ytterligare ökas genom anordnande av en slits som delar bladfjäderns fria ände .By arranging the leaf spring so that it abuts the brake shoe next to the bracket with resilient tongues which with their free ends extend in the circumferential direction of the brake disc and act on the brake shoe, it is achieved that the compressive force becomes softer and more uniformly distributed on the brake shoe. The softness of the spring can be further increased by arranging a slot which divides the free end of the leaf spring.
Om hällfjädern, som bestär av de tvä bladfjädrarna, är sä sammansatt att dessas likformiga ändar är ätskilda vid den punkt där fästorganet päverkar bromsbygeln, hälls fjädern i friktionskontakt med bromsbygeln sä snart den hakar pä bromsbygeln . Den är även säkrad i sitt läge när bromsbygeln de- monteras för utbyte av bromsbelägg.If the pouring spring, which consists of the two leaf springs, is so composed that their uniform ends are separated at the point where the fastening means acts on the brake caliper, the spring is poured into frictional contact with the brake caliper as soon as it hooks on the brake caliper. It is also secured in position when the brake caliper is disassembled to replace the brake pads.
Enligt en annan föredragen utföringsform av hällfjädern, bestär den av en bladfjäder som med var och en av sina ändar stöder pä en bromsback och hälls av en rektangulär vinkelformad del fäst vid dess baksida och fasthakad pä urtagningens vägg mitt emot kolven. I denna utföringsform kan kända enkla fzššššlïï ä” s 7907786-3 bladfjädrar användas . Tillverkningskostnaden kan därför reduceras .According to another preferred embodiment of the pouring spring, it consists of a leaf spring which with each of its ends rests on a brake shoe and is poured by a rectangular angular part attached to its back and hooked to the wall of the recess opposite the piston. In this embodiment, known simple fzššššlïï ä "s 7907786-3 leaf springs can be used. The manufacturing cost can therefore be reduced.
Eftersom hällfjädern, som har sin ena ände rätvinkllgt böjd och hakas fast i urtagningen i bromsbygeln, är utförd i ett stycke och med sin andra ände som är tungformig, stöder mot bromsbackarna, är tillverkningen mycket förenklad . Behovet av att sammanställa hällfjädern av flera element elimineras, eftersom fjädern kan stansas i ett stycke.Since the hob spring, which has one end bent at right angles and hooked into the recess in the brake caliper, is made in one piece and with its other end, which is tongue-shaped, supports against the brake shoes, the manufacture is very simplified. The need to assemble the pouring spring of several elements is eliminated, since the spring can be punched in one piece.
Om hällfjädern är sä utformad att tungan, som stöder mot bromsbacken intill kolven, är böjd i sådan vinkel mot bromsbackens rörelseriktning att den ut- övar en äterförande kraft pä bromsbacken, säkerställs att bromsbacken intill kolven förflyttas från bromsskivan efter varje bromsning. Denna effekt uppnäs mycket enkelt genom att den sektion, som ligger mellan fästpunkten och tungans ände på bromsbacken intill kolven, ges en krökning i riktning mot bromsskivan, vilken krökning griper in i bromsbackens underlagsplatta.If the pouring spring is designed so that the tongue, which rests against the brake shoe next to the piston, is bent at such an angle to the direction of movement of the brake shoe that it exerts a restoring force on the brake shoe, it is ensured that the brake shoe next to the piston moves away from each brake disc. This effect is achieved very simply by giving the section, which lies between the attachment point and the end of the tongue on the brake shoe next to the piston, a curvature in the direction of the brake disc, which curvature engages in the brake plate base plate.
Om bladfjädrarna i hällfjädern är sä utformade att deras fria ändar är böjda bakåt, inåt, blir fjäderkraften mjukare. Det är sålunda möjligt att ästad- komma en nästan konstant äterställningskraft under hela förslitningstiden för bromsbacken intill kolven genom att göra hällfjädern tungformig , bakåt- böjd , varvid krökningen pekar i riktning mot bromsbygelns radiellt yttre kant.If the leaf springs in the hob spring are designed so that their free ends are bent backwards, inwards, the spring force becomes softer. It is thus possible to achieve an almost constant restoring force during the entire wear time of the brake shoe next to the piston by making the pouring spring heavy, bent backwards, the curvature pointing in the direction of the radially outer edge of the brake caliper.

Ett glidstyrningsarrangemeng 13 häller bromsbygeln 2 axiellt förskjutbart i en bromshällare l som tar upp bromsmomentet och styr *Ü ' ÄL-'MÉ- ”gel f» : _, . _ qlà'_wá"'"'“vl' ïfefaïmàßi-:É '7907786-3 “ 4 bromsbackama 6 och 7 medelst armarna 4 och 5 över bromsskivan 3 . Ett päverkningsargan i bromsbygelns 2 ben 8 verkar med sin kolv 10 direkt pä bromsbacken 7 och pressar den till anliggning mot bromsskivan 3 för att sedan förflytta bromsbygeln 2 axiellt medelst reaktionskraften, vilket innebär att bromsbygelns ben 9 förflyttar även bromsbacken 6 till anliggning mot broms skivan. Bromsbygeln har en radiellt utåtriktad urtagning ll där en hällfjäder 12 är anordnad som är inpassad i urtagningen med litet spel i tvärled. Hällfjädern 12 , som visas förstorad i fig. 3 , innefattar tvä ovanpä varandra liggande bladfjädrar 14, 15 som är likformigt anslutna vid en ände 16.Pig. 1 and 2 show a brake with a floating brake caliper with a brake shoe holder according to the invention. A slide guide arrangement 13 pours the brake caliper 2 axially displaceable into a brake lever 1 which absorbs the braking torque and controls * Ü 'ÄL-'MÉ- "gel f": _,. _ qlà'_wá "'"' “vl 'ïfefaïmàßi-: É' 7907786-3“ 4 brake shoes 6 and 7 by means of arms 4 and 5 over the brake disc 3. An impact argon in the legs 8 of the brake caliper 2 acts with its piston 10 directly on the brake shoe 7 and presses it to abut against the brake disc 3 to then move the brake caliper 2 axially by the reaction force, which means that the brake caliper legs 9 also move the brake shoe 6 to abut against the brake disc. The brake caliper has a radially outwardly directed recess 11 where a pouring spring 12 is arranged which is fitted in the recess with a small play in the transverse direction. The pouring spring 12, shown enlarged in Fig. 3, comprises two superimposed leaf springs 14, 15 which are uniformly connected at one end 16.
Denna är böjd i rät vinkel och har en borrning 17 med en slits 18 . De likformigt anslutna ändarna befinner sig pä ett avständ Å frän varandra vid slitsen och ändama 19 , 20 , som ligger mitt emot änden 16 är böjda. inät, bakät med den längre änden 20 nägot böjd mot fjäderns baksida. Hällfjädern 12 är hakad pä en bult 21 som är fäst vid urtagningens ll vägg 22 mitt emot kolven 10. Bultens huvud 23 har en nägot mindre diameter än borrningen 17 i fjädern 12 , medan den underliggande sektionen 24 har en diameter som motsvarar bredden pä slitsen 18 i hällfjädernfsammansatt av bladfjädrarna 14, 15 . Bulten 21 har en andra sektion med mindre diameter, som sträcker sig genom en borrning 26 i urtagningens vägg 22 sä att steget 28 mellan sektionerna 24 och 25 anligger mot väggen 22 , medan delen 27 är utvidgad sä att bulten passar exakt i bromsbygeln 2 . Den inhakade fjädern 12 hälls av bulten medelst friktionskraft eftersom fjäderänden 16 mäste pressas samman vid inpassningen och i monterat skick kommer den att ytterligare pressas in i slitsen 18 som ett resultat av reaktions- kraften frän fjäderändama 19 , 20 somstöder mot bromsbackarna 6, 7 . Häll- fjädern 12 pressar bromsbackama till anliggning mot de radiella kontakt- ytorna 29, 30 pä bromsbärarens armar 4, 5 och fixeras . Pjäderändarna 19 , 20 är sä utformade att den ände 19 , som stöder mot bromsbacken intill bromsbygeln häller bromsbacken 6 i läge endast vid bromsbygelns 2 ben 9, medan fjäderänden 20 , som stöder mot bromsbacken 7 nära kolven, ästad- kommer en äterförande kraft pä bromsbacken utöver den radiella kraften som ett resultat av dess lutande läge relativt bromsbackens rörelseriktning mot bromsskivan. Den utböjning som är vänd mot bromsens yttre kant åstadkommer en i det närmaste konstant äterföringskraft eftersom fjädems minskande styvhet i riktning mot änden kompenseras av ökande utböjning.This is bent at right angles and has a bore 17 with a slot 18. The uniformly connected ends are located at a distance Å from each other at the slot and the ends 19, 20, which lie opposite the end 16, are bent. net, rear with the longer end 20 slightly bent towards the back of the spring. The pouring spring 12 is hooked onto a bolt 21 which is attached to the wall 22 of the recess 11 opposite the piston 10. The head 23 of the bolt has a slightly smaller diameter than the bore 17 in the spring 12, while the underlying section 24 has a diameter corresponding to the width of the slot 18 in the coil spring composite of the leaf springs 14, 15. The bolt 21 has a second section of smaller diameter, which extends through a bore 26 in the wall 22 of the recess so that the step 28 between the sections 24 and 25 abuts against the wall 22, while the part 27 is widened so that the bolt fits exactly in the brake caliper 2. The hooked spring 12 is poured off the bolt by frictional force because the spring end 16 must be compressed during fitting and in assembled condition it will be further pressed into the slot 18 as a result of the reaction force from the spring ends 19, 20 abutting the brake shoes 6, 7. The pouring spring 12 presses the brake shoes into abutment against the radial contact surfaces 29, 30 on the brake carrier arms 4, 5 and is fixed. The spring ends 19, 20 are designed so that the end 19, which abuts the brake shoe next to the brake caliper, pours the brake shoe 6 into position only at the brake caliper 2 legs 9, while the spring end 20, which supports the brake shoe 7 near the piston, provides a restoring force on the brake shoe. in addition to the radial force as a result of its inclined position relative to the direction of movement of the brake shoe towards the brake disc. The deflection facing the outer edge of the brake produces an almost constant return force as the decreasing stiffness of the spring towards the end is compensated by increasing deflection.
