Abstract

In the production of a brake shoe which comprises a carrier plate 22, an intermediate layer 24 and a friction lining 23, a heat-hardenable composition is mixed with a heat-actuatable adhesive, and the mixture is applied to a fibrous web 7 and is uniformly spread and then dried. An intermediate layer of appropriate size is then obtained from the composition and is subsequently joined to the carrier plate and a powdered friction layer material by pressing and heating to form the finished brake shoe. The intermediate layer may, prior to the application of the friction layer material and of heat and pressure, be bonded to the carrier plate using a solvent which partially activates the adhesive, so that the carrier plate and attached intermediate layer form a unit which can be stored prior to application thereto of the friction layer material.

Description

Û O 4-13- 8 hållfasthetsvärdena hos sålunda framställda bromsbackar ej tillförlitligt upp- når det önskade värdet, eftersom genom framställningsförfarandet för mellanplat- tan genom valsning eller dylikt en försegling av mellanplattans yta sker, som negativt påverkar vidhäftningen mellan friktionsmaterial och mellanplatta. in För avstämningen av mellanskiktet för anpassning till de förekommande kraven, såsom värmeisolering, ljuddämpning, förbindningshållfasthet, korrosions- skydd och dylikt, är vid detta förfarande trånga gränser satta, eftersom de erforderliga minsta hållfasthetsvärdena endast kan uppnås vid några få bland- ningsvarianter av mellanskiktmaterialet. - V Uppfinningen har till uppgift att åstadkomma ett sätt att framställa en A bromsback och en bromsback, vid vilket; resp. vid vilken vid förenklad produk- tion en hög skjuvhållfasthet hos belagen under bibehållande av de övriga önska- de positiva egenskaperna hos mellanskiktet, såsom ljuddämpning, värmeisolering; korrosionsskydd och dylikt, förenas med varandra hos brommbackeni Uppfinningen kännetecknns för detta ändamål av att mellanskiktmaterialet (compound), ett vär- meaktiverbart lim samt eventuella tillsatsämnen för inställning av den önskade viskositeten blandas med varandra och den pastösa blandningen anbringas på ett; glasfibernät och likformigt, dvs. med likformig tjocklek, stryks ut på glas- fibernätetg t.ex. fördelas genom rakling, varpå mellanskiktmaterialet torkas. The strength values of brake shoes thus produced do not reliably reach the desired value, since by the manufacturing process of the intermediate plate by rolling or the like a sealing of the intermediate plate surface takes place, which adversely affects the adhesion between friction material and intermediate plate. In order to match the intermediate layer to suit the requirements, such as thermal insulation, sound attenuation, bond strength, corrosion protection and the like, narrow limits are set in this process, since the required minimum strength values can only be achieved with a few mixed variants of the intermediate layer material. The object of the invention is to provide a method of producing an A brake shoe and a brake shoe, in which; resp. in which during simplified production a high shear strength of the coatings while maintaining the other desired positive properties of the intermediate layer, such as sound attenuation, thermal insulation; The invention is characterized for this purpose in that the intermediate layer material (compound), a heat-activatable adhesive and any additives for adjusting the desired viscosity are mixed with each other and the pasty mixture is applied to one another; fiberglass mesh and uniform, ie. with uniform thickness, spread on glass fiber mesh e.g. distributed by squeegeeing, after which the interlayer material is dried.

Från det så erhållna torkade mellanskiktmaterialet, företrädesvis som bana, kan genom skärning/stansning ett som bärplatta passande mellanskiktsplatt- -c stycke erhållas från banan och därpå förbindas med bärplattan och ett pulver- formigt friktionsskiktmaterial genom pressning och uppvärmning till den färdiga bromsbacken vid härdning av plastmaterialet. 9 Det värmeaktiverbara limmet, som är inarbetat i mellanskiktmaterialet, sörjer på bärplattsidan av mellanplattan för en god förbindning av bärplattan med mellanplattan. En god förbindning av friktionsmaterialet med mellanplattan erhålls genom att vid mellanplattans framställning visserligen en jämn yta före-' ligger, som säkerställer en definierad skiljelinje mellan friktionsmaterial och skiktmaterial, mellanskiktplattans yta på denna skiljelinje emellertid har en tillräcklig grovhet, som leder till ett särskilt bra ingrepp med friktionsmate- rialet. Detta ökar belagets skjuvhållfasthet avsevärt, i motsats till ett annars infört vals- och/eller pressförlopp vid mellanskiktet för framställning av en mellanplatta, som gör ytan för glatt. Dessutom ökar glasfibernätets skelettar- tade stödjande struktur mellanplattans hållfasthet och bidrar därmed icke oväsentligt till belagets nödvändiga skjuvhållfasthet gentemot bärplattan. _ Såsom visat sig kan det i mellanskiktmaterialet inarbetade, värmeaktiver- bara limmet även aktiveras genom lösningsmedel för lätta limningar. Denna om- ständighet utnyttjar man lämpligen genom att man genom anbringande av en droppe 3 sno 448 lösningsmedel åstadkommer en lätt vidhäftning mellan bärplatta och enligt upp- finningen framställd mellanskiktsplatta.a En på detta sätt förbehandlad bärplatta leder till ett avsevärt underlät- tande i produktionen, eftersom för bromsbackens färdigställande endast två delar, nämligen den förbehandlade bärplattan och det pulverformiga friktions- skiktmaterialet behöver förbindas genom pressning och uppvärmning till en broms- back. - “ För framställning använder man med fördel glasfiberväv med följande data: VGlasfiberväv med slingervävnadsbindning Trådfördelning hos varptrådarna ca 42- 8 per cmv Trådfördelning hos inslagstrådarna ca 2 - 3 per cm Trådnjockiek ca 0,6 - 1,2 mm -Den enligt uppfinningen framställda mellanplatta kan optimeras för olika ändamål.

The heat-activatable adhesive, which is incorporated in the intermediate layer material, ensures on the support plate side of the intermediate plate a good connection of the support plate with the intermediate plate. A good connection of the friction material with the intermediate plate is obtained by the fact that in the production of the intermediate plate there is admittedly a smooth surface which ensures a defined dividing line between friction material and layer material, however the surface of the intermediate layer plate on this dividing line has a sufficient roughness which leads to a particularly good engagement with the friction material. This increases the shear strength of the coating considerably, in contrast to an otherwise introduced rolling and / or pressing process at the intermediate layer for producing an intermediate plate, which makes the surface too smooth. In addition, the skeletal supporting structure of the fiberglass mesh increases the strength of the intermediate plate and thus does not insignificantly contribute to the necessary shear strength of the coating relative to the support plate. As has been shown, the heat-activatable adhesive incorporated into the interlayer material can also be activated by solvents for light gluing. This circumstance is suitably utilized by applying a drop of 3 sno 448 solvents by providing a light adhesion between the support plate and the intermediate layer plate prepared according to the invention. A support plate pretreated in this way leads to a considerable facilitation in the production. since for the completion of the brake shoe only two parts, namely the pretreated support plate and the powdered friction layer material, need to be connected by pressing and heating to a brake shoe. For production, fiberglass fabric is advantageously used with the following data: VGlastic fiber fabric with loop fabric binding Thread distribution of warp threads approx. 42-8 per cmv Thread distribution of weft threads approx. 2 - 3 per cm Thread thickness approx. 0.6 - 1.2 mm -The intermediate plate produced according to the invention can be optimized for different purposes.

Fig. 6 is a cross-section through a brake shoe manufactured according to the invention. When producing the intermediate plate, it is conveniently done so that first a large piece of web is produced continuously in a through-going process.

Utgångspunkt för framställningsförfarandet bildas av en massa, som exem- pelvis består av en av de tre tidigare nämnda blandningarna. Denna massa 1 blan- das intimt i en lösningsmedelknådare 4 under tillförsel av värmeaktiverbart lim 2 och eventuellt alltefter behov av viskositetsinställande tillsatsämnen 3, tills en pastös flytande massa uppstår. iDenna pasta kan därpå medelst en doseringspump 6 uttagas ur en förrådsbe- hållare 5. Genom doseringspumpen tillförs denna massa i riktiga mängder till en rakelanordning 9, som vid den som exempel angivna framställningsprocessen är ut- bildad som luftrakel; varvid vals- eller gummidukraklingsförfaranden även kan användas. Vid raklingsförloppet anbringas det pastformiga mellanskiktmaterialet med likformig tjocklek på ett från en rulle/spole uttaget glasfibernät 7. För att under produktionsprocessen detta mellanskiktmaterial ej skall häfta eller klibba vid transportanordningen, tillförs under glasfibernätet även silikonise- rat papper 8. _ _ “ Beroende av den torkningsgrad, som kan uppnås för de olika recepturerna i torksträckan 10, använder man ensidigt eller dubbelsidigt silikoniserat papper.The starting point for the production process is formed by a pulp, which for example consists of one of the three previously mentioned mixtures. This pulp 1 is intimately mixed in a solvent kneader 4 with the addition of heat-activatable glue 2 and possibly as required by viscosity-adjusting additives 3, until a pasty liquid mass is formed. This paste can then be taken out of a storage container 5 by means of a metering pump 6. Through the metering pump, this mass is supplied in correct quantities to a squeegee device 9, which in the exemplary manufacturing process is formed as an air squeegee; wherein rolling or rubber cloth cracking methods can also be used. During the squeegee process, the pasty intermediate layer material of uniform thickness is applied to a glass fiber mesh 7 taken from a roll / spool. In order for this intermediate layer material not to adhere or stick to the transport device during the production process, siliconized paper 8 is also fed under the glass fiber mesh. degree of drying, which can be achieved for the different recipes in the drying section 10, one-sided or double-sided siliconized paper is used.

Dubbelsidigt silikoniserat papper kommer till användning om efter torknings- -sträckan den under genomloppsprocessen uppnåeliga torkningsgraden hos mellan- skiktet är så ringa, att det finns risk för sammanklibbning av de enskilda mel- lanskiktlagren vid pålindning på en spole. I detta fall, som även ligger till grund för produktionsprocessen i fig. 1, skulle man då pålinda dubbelsidigt si- likoniserat papper tillsammans med det bandformiga mellanskiktet till spolar. V Vid tillräcklig torkningsgrad används endast ensidigt silikoniserat papper, som då avlägsnas före pålindningen till spolar 12. Vid båda metoderna är efter torkningssträckan även en åtskiljningsanordning 11 anordnad (t.ex. cirkel- knivskäranordning), i vilken bandmaterialet spaltas till de för den vidare bear- betningen erforderliga bredderna, innan det upplindas till spolar 12 med olika bredder.Double-sided siliconized paper is used if, after the drying stretch, the degree of drying of the intermediate layer achievable during the passing process is so small that there is a risk of the individual intermediate layer layers sticking together when wound on a spool. In this case, which is also the basis for the production process in Fig. 1, double-sided siliconized paper would then be wound together with the strip-shaped intermediate layer into coils. At a sufficient degree of drying, only one-sided siliconized paper is used, which is then removed before the winding to spools 12. In both methods, after the drying distance, a separating device 11 is also arranged (eg circular knife cutting device), in which the strip material is split into those for further processing. pickling the required widths, before it is wound into coils 12 of different widths.

Efter transport och eventuell förrådslagring utskärs/utstansas mellan- plattor från mellanskiktmaterialet 13 med den för mellanplattans dimensionering riktiga bredden, i en skär- eller stansanordning 15.After transport and possible storage, intermediate plates are cut / punched out of the intermediate layer material 13 with the width correct for the dimensioning of the intermediate plate, in a cutting or punching device 15.

Vid användning av dubbelsidigt silikoniserat papper, vilket medupplindas på spolen, avlägsnas detta vid 14 före stansnings-/skärningsförloppet från det bandformiga mellanskiktmaterialet. Efter stansnings-/skärförloppet, under vilket mellanplattans 24 kontur (fig. 3) fastställs i motsvarighet till ytterkonturen hos friktionsbelaget och förankringshål i belagbärplattan fastställs, sker nu íš (J O 14 4 8 Uï tiilförsei av en ïiten mängd ïösningsmedei 16 på den sida av meiïanpiattan 24, som är vänd mot bärpiattan 22 (fig. 2). Detta lösningsmedel åstadkommer en ïätt aktivering av det i meiianskiktsmateriaiet inarbetade iimmet; Éfter tiiiförsei 17 av belagbärpiattan 22 påïäggs meilanplattan 24 konturriktigt på bärpiattan och kan pressas mot denna under iätt tryck 18. Det genom iösningsmedïet aktive- rade ïimmet åstadkommer därvid en lätt fastkiibbning meiian bärpiatta och meiianpiatta.When using double-sided siliconized paper, which is co-wound on the spool, this is removed from the strip-shaped intermediate layer material at 14 before the punching / cutting process. After the punching / cutting process, during which the contour of the intermediate plate 24 (Fig. 3) is determined corresponding to the outer contour of the friction liner and anchoring holes in the liner support plate are now formed, a small amount of liner 16 on the side of the liner is provided. 24, which faces the support plate 22 (Fig. 2) .This solvent provides a proper activation of the core incorporated in the multilayer material; After 17 is provided by the coating support plate 22, the meilan plate 24 is applied contiguously to the support plate and can be pressed against it under pressure 18. the ïmm activated by the solution medium thereby provides an easy attachment to the carrier and the carrier.

Den nu med meiianplattan förberedda bärpiattan (fig. 4) biidar en sjäiv- ständigt manipuïerbar förbindningsenhet, som kan meiianïagras i förråd före vidarebearbetningen. ' _ 9 V Den förkonfektionerade bärpïattan (fig. 4) inïäggs nu i pressen 20 och pressas med det puiverformiga friktionsmateriaiet 19 tili bromsbacken. Fig. 5 visar denna bromsback 21, varvid man tydiigt kan se att meïïanpiattans 24 yttre kontur exakt svarar mot friktionsbeiagets 23 ytterkontur. A _ Bromsbacken (fig. 5), som uppvisar en bärpiatta 22 med förutbestämd kon-- figuration och ett friktionsbeiag 23, innehåiier ett meïianskiktspiattstycke 24, som är biidat av en blandning av meïianskiktmateriaiet och ett värmeaktiverbartd iim, i viiken biandning ett giasfibernät 7när inbäddat. Meïianskiktspiattstycket har ïikformig tjocklek och har en Jämnt förïöpande och grov yta 26 och 27.The carrier plate now prepared with the meian plate (Fig. 4) provides an independently manipulable connecting unit, which can be meianiagrassed in storage before further processing. The preconfected carrier plate (Fig. 4) is now loaded into the press 20 and pressed with the powder-shaped friction material 19 to the brake shoe. Fig. 5 shows this brake shoe 21, whereby it can be clearly seen that the outer contour of the median plate 24 corresponds exactly to the outer contour of the friction pad 23. The brake jaw (Fig. 5), which has a support plate 22 with a predetermined configuration and a friction attachment 23, contains a multilayer spacer 24 which is formed by a mixture of the multilayer material and a heat-activatable material, in which a mixture is applied. . The meiianskiktspiat piece has a uniform thickness and has an evenly sloping and rough surface 26 and 27.

Genom säkerstäiiande av den erforderiiga skjuvhåiïfastheten för bromsbac- ken är det möjiigt att optimera meiianskiktets egenskaper inom en vid ram genom modifikation av recepturen för meiïanskiktmassan för oiika fordringar, såsom värmeisoïering, ljuddämpning, förbindningshåiïfasthet och korrosionsskydd, och samtidigt säkerstäiïa ett förenkiat handhavande under produktionen.By ensuring the required shear strength of the brake jaw, it is possible to optimize the properties of the mein layer within a wide frame by modifying the recipe for the mein layer mass for different requirements, such as thermal insulation, sound attenuation, joint strength and corrosion protection while maintaining protection.
