Description

457 470 2 Pig 1 visar en vy av en delbeläggskivbroms. 457 470 2 Pig 1 shows a view of a sub-disc brake.

Fig 2 visar bromsen enligt fig l sedd uppifrån.Fig. 2 shows the brake according to Fig. 1 seen from above.

Fig 3 visar ett tvärsnitt längs linjen A-A av en broms enligt fig l.Fig. 3 shows a cross section along the line A-A of a brake according to Fig. 1.

Bromsen visad på ritningarna är avsedd att monteras i ett motorfordon. Den är försedd med en bromsbärare Z fast- bultad eller på annat sätt fixerad vid en drivspindel, en axel eller något annat organ i hjulupphängningen i ett fordon pà den sida som är vänd mot bromsskivan 8 medelst monteringsöppningar 4, 6. Bromsbäraren 2 bildas av tvá bromsbärararmar 10, 12 huvudsakligen anordnade i V-form och försedda med borrningar i sina radiellt yttre ändar, varvid en av borrningarna, 14 är visad i fig 3. Denna borrning 14 i bromsbärararmen 10 är anordnad i en ansats 18 som sträcker sig axiellt vid den bortre änden av broms- bärararmen 10. Ett bärstift 22 fäst vid bromsbygeln 20 upptas axiellt förskjutbart i borrningen 14 sàsonl kommer att beskrivas närmare nedan. I den andra ej visade borrning- en i bromsbärararmen 12, är ett axiellt styrstift anordnat, vilket är axiellt förskjutbart i en axiell borrning i bromsbygeln. Dessutom kan styrsystemet för bromsbygeln vara så anordnat, att stiftet 22 upptas i bromsbärararmen och den axiella borrningen 14 i bromsbygeln 20.The brake shown in the drawings is intended to be mounted in a motor vehicle. It is provided with a brake carrier Z bolted or otherwise fixed to a drive spindle, axle or other member of the wheel suspension in a vehicle on the side facing the brake disc 8 by means of mounting openings 4, 6. The brake carrier 2 is formed by two brake carrier arms 10, 12 arranged substantially in V-shape and provided with bores at their radially outer ends, one of the bores 14 being shown in Fig. 3. This bore 14 in the brake carrier arm 10 is arranged in a shoulder 18 extending axially at the the far end of the brake carrier arm 10. A support pin 22 attached to the brake caliper 20 is received axially displaceably in the bore 14 as will be described in more detail below. In the second bore (not shown) in the brake support arm 12, an axial guide pin is provided, which is axially displaceable in an axial bore in the brake caliper. In addition, the control system for the brake caliper can be arranged so that the pin 22 is received in the brake carrier arm and the axial bore 14 in the brake caliper 20.

Bromsbygeln 20 är huvudsakligen skalformad och innefattar den första radiell skänkel 28 bildande en bromscylinder , vilken upptar en ej visad bromskolv. Skänkeln 28 övergår i en bryggdel 34, som omsluter bromsskivan 8. På sin andra sida avslutas bryggdelen 34 med en andra radiell skänkel 36. Bredvid bromscylindern 30 finns en axiell borrning 38 i skänkeln 28, i vilken borrning stiftet 22 är fixerat, vilket sålunda även sträcker sig i axiell riktning. Med sin fria ände som sträcker sig ut ur borrningen 38, gär Stiftet 22 in i borrningen 14 i bromsbärararmen. 10 och är axiellt förskjutbar i denna. Den fria änden av stiftet 3 457 470 22 kan lämpligen vara försedd med ett smörjspár 23, som sträcker sig spiralformigt runt periferin. Diametrarna hos stiftet 22 och borrningen 14 är anpassade så att stiftet 22 utgör en fixerad lagring tillsammans med borrningen 14. Detta innebär att mycket snäva toleranser för styrnihgen erhålls.The brake caliper 20 is substantially shell-shaped and includes the first radial leg 28 forming a brake cylinder which receives a brake piston (not shown). The leg 28 merges into a bridge part 34, which encloses the brake disc 8. On its other side, the bridge part 34 terminates with a second radial leg 36. Next to the brake cylinder 30 there is an axial bore 38 in the leg 28, in which bore the pin 22 is fixed, which thus also extends in the axial direction. With its free end extending out of the bore 38, the pin 22 moves into the bore 14 in the brake carrier arm. 10 and is axially displaceable therein. The free end of the pin 3 457 470 22 may suitably be provided with a lubrication groove 23 which extends helically around the periphery. The diameters of the pin 22 and the bore 14 are adapted so that the pin 22 forms a fixed bearing together with the bore 14. This means that very tight tolerances for the guide are obtained.

Inne i styrningen mellan stiftet 22 och borrningen 14 finns ett mellanskikt 40 bestående av minst två komponenter anordnade ovanpà varandra, varvid skiktet 40 anbringas pà stiftet 22 alternativt pä liknande sätt i borrningen 14. Detta mellanliggande skikt förhindrar permanent en metallisk kontakt mellan de ingående delarna. Skiktet innefattar ett vidhäftande skikt anbringat direkt pà metall- ytan och består lämpligen av ett zinkfosfatskikt med en tjocklek pà 3 till 5/Å(. Pà zinkfosfatskiktet anbringas ett glidskikt med en tjocklek av 5 till 20/51, lämpligen 12 É4/M. Glidskiktet innefattar ett torrsmörjningssystem bestående av molybdensulfit och grafit i. en värmehärdande harts. I stället för molybdensulfit och grafit kan flour- karbon användas som ett alternativ. Dessutom kan smörjning med ett specialsmörjmedel användas.Inside the guide between the pin 22 and the bore 14 there is an intermediate layer 40 consisting of at least two components arranged on top of each other, the layer 40 being applied to the pin 22 alternatively in a similar manner in the bore 14. This intermediate layer permanently prevents a metallic contact between the constituent parts. The layer comprises an adhesive layer applied directly to the metal surface and preferably consists of a zinc phosphate layer with a thickness of 3 to 5 / Å (. On the zinc phosphate layer a sliding layer with a thickness of 5 to 20/51 is applied, preferably 12 É4 / M. The sliding layer comprises a dry lubrication system consisting of molybdenum sulphite and graphite in a thermosetting resin, instead of molybdenum sulphite and graphite fluorocarbon can be used as an alternative, in addition lubrication with a special lubricant can be used.

Metoden för att tillverka stiftstyrningen innefattar i ett förbehandlingssteg pàförande av det vidhäftande skiktet av zinkfosfat på en eller flera komponenter i_styrningen, dvs på styrstiftet 22 eller väggen i borrningen 14. Sedan pàförs det yttre glidskiktet, varefter en värmebehandling sker under en timme lämpligen vid en temperatur av l80°C.The method of manufacturing the pin guide comprises in a pretreatment step applying the adhesive layer of zinc phosphate to one or more components of the guide, i.e. to the guide pin 22 or the wall of the bore 14. Then the outer sliding layer is applied, after which a heat treatment takes place for one hour. of 180 ° C.

Slutligen pàförs smörjmedel i ett sista steg.Finally, lubricant is applied in a final step.

Det är vidare möjligt att pàföra glidskiktet direkt på metallytan utan ett mellanliggande vidhäftande skikt.It is further possible to apply the sliding layer directly to the metal surface without an intermediate adhesive layer.
