Description
Bremseskive for skivebremser. Brake disc for disc brakes.
Den foreliggende oppfinnelse angår en bremseskive for skivebremser, forsynt med en friksjonsring av støpejern, som er slik forbundet med et navlegeme av støpestål eller lignende materiale at den bare kan bevege seg radialt på dette. The present invention relates to a brake disc for disc brakes, provided with a friction ring of cast iron, which is so connected to a hub body of cast steel or similar material that it can only move radially on this.
Ved tidligere kjente bremseskiver av denne art er der mellom navlegemet og friksjonsringen anordnet anslag som virker i aksial- og/eller omkretsretningen, og som utgjøres av de nevnte deler eller av mel-lomledd. Samtidig er friksjonsringen sam-mensatt av flere deler hvorved bremseskiven fordyres og krever regelmessig tilsyn og kontroll under drift. In the case of previously known brake discs of this type, there is an abutment arranged between the hub body and the friction ring which acts in the axial and/or circumferential direction, and which is made up of the aforementioned parts or of intermediate joints. At the same time, the friction ring is composed of several parts, whereby the brake disc becomes more expensive and requires regular supervision and control during operation.
Den oppgave som ligger til grunn for oppfinnelsen, er å skaffe en bremseskive av den innledningsvis angitte art som kan fremstilles på enkel og billig måte og ikke har noen deler som må overvåkes under drift. The task underlying the invention is to provide a brake disc of the type indicated at the outset which can be produced in a simple and inexpensive way and has no parts which must be monitored during operation.
Ifølge oppfinnelsen blir denne oppgave løst ved at navlegemet har radialt forlø-pende føringsflater som virker i aksial- og omkretsretningen og samvirker med motliggende flater på friksjonsringen, som er støpt i ett stykke rundt navlegemet under unngåelse av sammensveising. According to the invention, this task is solved by the hub body having radially extending guide surfaces which act in the axial and circumferential direction and cooperate with opposite surfaces on the friction ring, which is cast in one piece around the hub body while avoiding welding together.
Ifølge oppfinnelsen kan bremseskiven fordelaktig utformes slik at navlegemet har radialt utadrettede tapper, og at steg på friksjonsringen er støpt rundt tappens mantelflater, eller slik at navlegemet på sin omkretsflate har et ringformet steg og at partier av friksjonsringen er støpt rundt According to the invention, the brake disc can advantageously be designed so that the hub body has radially outwardly directed studs, and that steps on the friction ring are molded around the pin's mantle surfaces, or so that the hub body has an annular step on its peripheral surface and that parts of the friction ring are molded around
I steget bare på et smalt kantparti ved dettes omkrets. In the step only on a narrow edge part at its circumference.
Ved den sistnevnte utførelse er det videre ifølge oppfinnelsen fordelaktig at steget strekker seg radialt utover til i nærheten av bremseskivens omkrets og bare ved sine ytre partier er omgitt av friksjonsringen. In the latter embodiment, it is furthermore advantageous according to the invention that the step extends radially outwards to near the circumference of the brake disc and is only surrounded by the friction ring at its outer parts.

På alle figurer er til hinannen sva-rende deler forsynt med de samme henvis-ningstall. In all figures, corresponding parts are provided with the same reference numbers.
I utførelsen på fig. 1 og 2 har et nav-parti 10 minst tre radiale armer 11 hvorfra der rager ut tapper 12, likeledes i radial retning. Rundt navdelen 10 er der støpt en friksjonsring 13 bestående av to skiver 14 som er forbundet med ventilasjonsribber 15 til transport av kjøleluft. De to skiver 14 In the embodiment in fig. 1 and 2, a hub part 10 has at least three radial arms 11 from which studs 12 protrude, likewise in the radial direction. A friction ring 13 consisting of two disks 14 which are connected by ventilation ribs 15 for transporting cooling air is molded around the hub part 10. The two discs 14
er videre forbundet ved steg 16 som tappene 12 strekker seg igjennom. Ved støp-ningen av friksjonsringen 13 må det ved egnede kjente forholdsregler sørges for at stegene ikke blir sveiset til tappene 12. Dis-se forholdsregler kan f. eks. bestå i at tappene 12 gnis inn med en grafittholdig kokil-lesmøring før friksjonsringen 13 støpes. is further connected at step 16 through which the pins 12 extend. When casting the friction ring 13, it must be ensured by suitable known precautions that the steps are not welded to the pins 12. These precautions can e.g. consist of the pins 12 being rubbed in with a graphite-containing mold lubricant before the friction ring 13 is cast.
Under drift overfører armene 11 og tappene 12 let dreiemoment fra navdelen 10 til stegene 16 og dermed til friksjonsringen 13 mot hvis skiver 14 der presses ikke viste bremsebakker. Ved oppvarmning kan friksjonsringen 13 utvide seg uhindret av navdelen 10, idet stegene 16 glir utover på tappene 12. Herunder forblir friksjonsringen 13 sentrert i forhold til navlegemet 10. Armene 11 medfører en bestemt ringspalte mellom omkretsen av det sylindriske parti av navdelen 10 og innerkanten av skivene 14. Gjennom denne spalte blir der under bremseskivens omdreining suget inn kjøle-luft som av ventilasjonsribbene 15 pumpes ut ved omkretsen. During operation, the arms 11 and the pins 12 transfer light torque from the hub part 10 to the steps 16 and thus to the friction ring 13 against whose disks 14 there are pressed brake shoes not shown. When heated, the friction ring 13 can expand unimpeded by the hub part 10, as the steps 16 slide outwards on the pins 12. Below this, the friction ring 13 remains centered in relation to the hub body 10. The arms 11 cause a certain annular gap between the circumference of the cylindrical part of the hub part 10 and the inner edge of the disks 14. Cooling air is sucked in during the revolution of the brake disk through this gap, which is pumped out by the ventilation ribs 15 at the circumference.
Som vist på fig. 3 og 4 kan der på den sylindriske omkretsflate av navdelen 10 sit-te et ringformet steg 21 som har partier 23 med aksialt utragende ansatser, og som ved sin frie omkretsflate og de radialt ytterst-liggende partier av sine sideflater er omgitt av en sylinder 25 som forbinder de to skiver 14 i nærheten av deres innerkanter. Det må her ved støpningen av friksjonsringen 13 påses at denne ikke sveiser seg til navdelen 10. Sylinderen 25 har åpninger 27 til inn-sugning av kjøleluft som drives radialt utover av ventilasjonsribbene 15 under bremseskivens rotasjon. As shown in fig. 3 and 4, there can be an annular step 21 on the cylindrical peripheral surface of the hub part 10 which has parts 23 with axially projecting projections, and which is surrounded by a cylinder 25 on its free peripheral surface and the radially outermost parts of its side surfaces which connects the two disks 14 near their inner edges. When casting the friction ring 13, it must be ensured that it does not weld to the hub part 10. The cylinder 25 has openings 27 for the intake of cooling air which is driven radially outwards by the ventilation ribs 15 during the rotation of the brake disc.
Omkretsflaten av steget 21 gir sammen med fortykkelsene 23 en sentrering av friksjonsringen 13, som uhindret kan utvide seg. Sideflatene av partiene 23 samvirker med ved støpningen dannede motliggende flater på sylinderen 25 for å tjene som dreiemomentkobling mellom navlegemet 10 og friksjonsringen 13. The circumferential surface of the step 21 together with the thickenings 23 provides a centering of the friction ring 13, which can expand unimpeded. The side surfaces of the parts 23 cooperate with the opposing surfaces of the cylinder 25 formed during the casting to serve as a torque coupling between the hub body 10 and the friction ring 13.
Til forsterkning av kjøleluftstrømmen er det fordelaktig, som vist på fig. 5, å ut-forme navdelen 10 med et steg 31 som strekker seg utover til i nærheten av bremseskivens omkrets, og ved omkretsen av friksjonsringen 13 å anordne ribber 33 som forbinder skivene 14 med en ring 35 som er støpt rundt den frie omkretsflate og de ytre deler av sideflatene av steget 31. Samtidig har steget 31 i likhet med den ovenfor beskrevne utførelse aksiale eller radiale ansatser for overføring av dreiemomenter. På begge sider av steget 31 strekker der seg ventilasjonsribber 37 fra ringen 35 til skivene 14. Under bremseskivens rotasjon su-ger ribbene 37 kjøleluft inn gjennom et stort tverrsnitt og videre ut i det fri gjennom åpninger som befinner seg ved bremseskivens omkrets og begrenses av skivene 14, ringen 35 og ribbene 33. Da de åpninger som begrenser kjøleluftstrømmen, således ligger ved bremseskivens omkrets, kan de gjøres vesentlig større enn ved den ovenfor beskrevne utførelse. For strengthening the cooling air flow, it is advantageous, as shown in fig. 5, to design the hub part 10 with a step 31 which extends outwards to near the circumference of the brake disc, and at the circumference of the friction ring 13 to arrange ribs 33 which connect the discs 14 with a ring 35 which is molded around the free circumferential surface and the outer parts of the side surfaces of the step 31. At the same time, the step 31, like the above-described embodiment, has axial or radial projections for the transmission of torques. On both sides of the step 31, ventilation ribs 37 extend from the ring 35 to the discs 14. During the rotation of the brake disc, the ribs 37 suck cooling air in through a large cross-section and further out into the open through openings located at the circumference of the brake disc and limited by the discs 14, the ring 35 and the ribs 33. Since the openings which limit the flow of cooling air are thus located at the circumference of the brake disc, they can be made significantly larger than in the above-described design.
