Description

Oppfinnelsen vedrører pal-og palkrans-drivanordninger, mer særskilt en slik drivanordning for et frikransnav på en sykkel. The invention relates to pal and palkrans drive devices, more particularly such a drive device for a freewheel hub on a bicycle.

Anordningen ifølge oppfinnelsen egner seg særlig godt for brukThe device according to the invention is particularly suitable for use

i et sykkel-fr ikransnav med et drivelement innbefattende flere kjedehjul, en navhylse og en derimellom anordnet pal- og palkrans-dr ivanordning . Drivkjeden kan bringes til inngrep med kjedehjulene i samsvar med den ønskede gir innstilling. in a bicycle freewheel hub with a drive element including several sprockets, a hub sleeve and a pulley and pulley drive device arranged in between. The drive chain can be brought into engagement with the sprockets in accordance with the desired gear setting.

Kjente pal- og palkrans-drivanordninger innbefatter en første rotorenhet og en andre rotorenhet, idet disse rotorenheter har en felles rotasjonsakse. På den første rotorenhet er det montert en pal. Denne palen er utformet med et parti for samvirke med palkransen og med et sylindersegmentformet opplagrinsparti. Det sylindersegmentformede opplagrinsparti er svingbart opptatt i en komplimentær sylindersegmentformet utsparing i det første rotorenhet. Det sylindersegmentformede opplagringsparti og den sylindersegmentformede utsparing har en svingeakse som er parallell med den nevnte felles rotasjonsakse. Den andre rotorenhet innbefatter en palkrans som i det minste delvist strekker seg sammen med palen langs den felles akse. Palens inngrepsparti kan bringes til inngrep med palkransen under påvirkning av en sirkulær fjærring som krysser palens inngrepsparti til samvirke med palkransen og dessuten tjener til aksial fastgjøring av palen i forhold til den første rotorenhet. Som følge herav er palen forsynt med et spor på Known pal and palkrans drive devices include a first rotor unit and a second rotor unit, these rotor units having a common axis of rotation. A pawl is mounted on the first rotor unit. This pile is designed with a part for cooperation with the pile ring and with a cylindrical segment-shaped bearing part. The cylindrical segment-shaped storage part is pivotally engaged in a complementary cylindrical segment-shaped recess in the first rotor unit. The cylindrical segment-shaped storage part and the cylindrical segment-shaped recess have a pivot axis which is parallel to the aforementioned common axis of rotation. The second rotor unit includes a pole ring which at least partially extends with the pole along the common axis. The engagement part of the pawl can be brought into engagement with the pawl ring under the influence of a circular spring ring which crosses the engagement part of the pawl to cooperate with the pawl ring and also serves to axially fix the pawl in relation to the first rotor unit. As a result, the pole is provided with a track on it

et sted mellom sine aksiale ender. Dette sporet begrenses av to motliggende sideflater som er perpendikulære på den felles akse, og begrenses dessuten av en bunnflate som vender mot palkransen. I dette sporet er den sirkulære fjærring opptatt på en slik måte at fjærringens akse stemmer overens med driv-anordningens felles akse. Fjærringen virker mot sporets sideflater og virker også mot bunnflaten i sporet i en i hovedsaken radiell retning, for derved å presse palens inngrepsparti til inngrep med palkransen. For fastgjøring av fjærringen somewhere between its axial ends. This groove is limited by two opposite side surfaces that are perpendicular to the common axis, and is also limited by a bottom surface that faces the paling ring. In this groove, the circular spring ring is engaged in such a way that the axis of the spring ring agrees with the drive device's common axis. The spring ring acts against the side surfaces of the track and also acts against the bottom surface of the track in a mainly radial direction, thereby pressing the engaging part of the pawl into engagement with the pawl collar. For fixing the spring ring

mot aksial bevegelse i forhold til den første rotorenhet, og også for å holde palen mot aksial bevegelse i forhold til den første rotorenhet er fjærringen opptatt i et sirkulært spor i den første rotorenhet. Dette sirkulære spor i den første rotorenhet er vanskelig å fremstille, særlig i de tilfeller hvor palen og fjærringen skal anordnes på en radielt innover-rettet omkr.etsflate på den første rotorenhet. against axial movement in relation to the first rotor unit, and also to hold the pawl against axial movement in relation to the first rotor unit, the spring ring is engaged in a circular groove in the first rotor unit. This circular groove in the first rotor unit is difficult to produce, particularly in cases where the pawl and the spring ring are to be arranged on a radially inwardly directed encircling surface of the first rotor unit.

Foreliggende oppfinnelse tar sikte på å tilveiebringe en pal-og palkrans-drivanordning hvor fremstillingen av den første rotorenhet kan forenkles derved at man unngår det ringformede spor som man hittil har måttet fremstille ved maskinering. The present invention aims to provide a pawl and pawl ring drive device where the production of the first rotor unit can be simplified by avoiding the annular groove that has hitherto had to be produced by machining.

Oppfinnelsen vedrører således en pal- og palkrans-drivanordning, særlig for sykkel-fr ikransnav, hvilken anordning innbefatter en første rotorenhet og en andre rotorenhet, idet disse rotorenheter har en felles rotasjonsakse. Den første rotorenhet innbefatter i det minste én pal som har et parti beregnet for inngrepssamvirke med en palkrans og også har et sylindersegmentformet opplagringsparti. Det sylindersegmentformede opplagringsparti er svingbart opptatt i en sylinder-segmentf ormet utsparing i den første rotorenhet, og det sylin-der segmentf ormede opplagringsparti og den sylindersegmentformede utsparing har en svingeakse som går parallelt med den felles rotasjonsakse. Den andre rotorenhet innbefatter en palkrans som i det minste delvist strekker seg sammen med palen langs den felles rotasjonsakse. Palens inngrepsparti kan bringes til samvirke med palkransen. Palen er forsynt med et spor som begrenses av to motliggende sideflater perpendikulært på den felles akse, og videre begrenses av en bunnflate som vender mot palkransen. Dette spor opptar en sirkulær fjærring hvis akse i hovedsaken faller sammen med den felles nevnte akse. Fjærringen ligger an mot sideflatene og virker også mot bunnflaten i sporet i en i hovedsaken radiell retning, for derved å presse palens inngrepsparti til samvirke med palkransen. Fjærringen er sikret mot aksial bevegelse i forhold til den første rotorenhet i den første aksialretning utelukkende ved hjelp av fjærring-anslagsmidler på den første rotorenhet, hvilke midler har direkte samvirke med fjærringen, og er sikret mot aksialbevegelse i en andre aksialretning ved hjelp av palen, idet palen er sikret mot aksialbevegelse i forhold til den første rotorenhet i denne andre aksiale retning derved at det på den første rotorenhet er utformet en pal-anslagsflate. The invention thus relates to a pole and pole ring drive device, particularly for bicycle hubs, which device includes a first rotor unit and a second rotor unit, these rotor units having a common axis of rotation. The first rotor unit includes at least one pawl which has a part intended for engagement cooperation with a pawl ring and also has a cylindrical segment-shaped bearing part. The cylinder-segment-shaped storage part is pivotably engaged in a cylinder-segment-shaped recess in the first rotor unit, and the cylinder-segment-shaped storage part and the cylinder-segment-shaped recess have a pivot axis that runs parallel to the common axis of rotation. The second rotor unit includes a pole ring which at least partially extends together with the pole along the common axis of rotation. The engagement part of the palen can be brought into cooperation with the palen ring. The pile is provided with a groove that is limited by two opposite side surfaces perpendicular to the common axis, and further limited by a bottom surface that faces the pile rim. This slot accommodates a circular spring ring whose axis essentially coincides with the commonly mentioned axis. The spring ring rests against the side surfaces and also acts against the bottom surface of the groove in a mainly radial direction, thereby pressing the engaging part of the pawl into cooperation with the pawl ring. The spring ring is secured against axial movement relative to the first rotor unit in the first axial direction exclusively by means of spring ring abutment means on the first rotor unit, which means interact directly with the spring ring, and is secured against axial movement in a second axial direction by means of the pawl, the pawl being secured against axial movement in relation to the first rotor unit in this second axial direction by the fact that a pawl abutment surface is formed on the first rotor unit.

Ifølge oppfinnelsen kan den første rotorenhet innbefatteAccording to the invention, the first rotor unit may include

et rotor-grunnlegeme, idet en palbærerring er festet til dette grunnlegeme. Den sylindersegmentformede utsparing kan strekke seg over hele lengden til palbærerringen, idet én aksial ende av den sylindersegmentformede utsparing er lukket av en ringflate på rotor-grunnlegemet, hvilken ringflate i hovedsaken er perpendikulær på den nevnte felles akse og virker som pal-anslagsflate. a rotor base body, a pallet bearing ring being attached to this base body. The cylindrical segment-shaped recess can extend over the entire length of the pawl carrier ring, one axial end of the cylindrical segment-shaped recess being closed by an annular surface on the rotor base body, which annular surface is essentially perpendicular to the aforementioned common axis and acts as a pawl abutment surface.

Ifølge oppfinnelsen kan fremstillingen av anordningen forenkles, ikke bare med hensyn til å unngå et omløpende spor i rotoren-heten, men også med hensyn til å forenkle fjærringanordningen. According to the invention, the manufacture of the device can be simplified, not only with regard to avoiding a circumferential groove in the rotor unit, but also with regard to simplifying the spring ring arrangement.

En ytterligere fordel med den nettopp omtalte utførelsesformA further advantage of the embodiment just mentioned

av oppfinnelsen er at palbærerringen bare har en liten aksial-dimensjon, som eventuelt bare er litt større enn palens aksial-dimensjon. Palbærerringen kan fremstilles ved koldpressing, smiing eller fortrinnsvis ved hjelp av sintringsmetodikk, og maskineringen kan reduseres til et minimum eller sågar helt utelates. of the invention is that the pawl bearing ring only has a small axial dimension, which is possibly only slightly larger than the axial dimension of the pawl. The pallet bearing ring can be produced by cold pressing, forging or preferably by means of sintering methodology, and the machining can be reduced to a minimum or even completely omitted.

Oppfinnelsen skal forklares nærmere under henvisning til tegningene, hvor: Figur 1 viser et halvsnitt gjennom en pal-og palkrans-drivanordning , figur 2 viser et riss som i figur 1, hvor palen og den andre rotorenhet er fjernet for derved bedre å vise samvirket mellom fjærringen og den ringformede ribbe, The invention shall be explained in more detail with reference to the drawings, where: Figure 1 shows a half-section through a pawl and pawl ring drive device, Figure 2 shows a drawing as in Figure 1, where the pawl and the other rotor assembly has been removed to thereby better show the interaction between the spring ring and the annular rib,

I figur 1 er en navaksel betegnet med 10. På denne navakselen er det festet et lagerlegeme 12. En navhylse 14, fremstilt av en lettmetall-legering, er dreibart montert på lagerlegemet 12 ved hjelp av et kulelager 16. Navhylsen 14 er forsynt med en ringformet lagerskål 18 av stål og presset inn i navhylsen 14. En palbærerring 20 er anbragt i navhylsen 14. Denne palbærerring 20 er vist mer detaljert i figurene 3 og 4. Palbærerringen 20 er forsynt med små knaster på sin ytre omkretsflate, som er antydet med henvisningstall 22 i figur 4. Denne omkretsflate 22 har dreiemoment-overføringssamvirke med den indre omkrets-flaten til en aksialt rettet flens 24 på navhylsen 14. Som antydet i figurene 3 og 4 er palbærerringen 20 forsynt med lommer 26 i sin indre omkretsflate. Disse lommer 26 innbefatter, som vist i figur 3, sylindersegmentformede utsparinger 28. Som vist i figurene 1 og 5 er det i hver lomme 28 anordnet en pal 30. Palen 30 har et parti 32 beregnet for inngrepssamvirke med en palkrans, og har også et sylindersegmentformet opplagringsparti 34 hvormed palen er svingbart opptatt i den sylindersegmentformede utsparing 28. Palen er vist mer detaljert i figur 6. Palen 30 er forsynt med et spor 36 som begrenses av to sideflater 36a, 36 b og av en bunnflate 36c. In Figure 1, a hub shaft is denoted by 10. A bearing body 12 is attached to this hub shaft. A hub sleeve 14, made of a light metal alloy, is rotatably mounted on the bearing body 12 by means of a ball bearing 16. The hub sleeve 14 is provided with a annular bearing cup 18 made of steel and pressed into the hub sleeve 14. A pallet bearing ring 20 is placed in the hub sleeve 14. This pallet bearing ring 20 is shown in more detail in Figures 3 and 4. The pallet bearing ring 20 is provided with small knobs on its outer peripheral surface, which are indicated by reference number 22 in figure 4. This circumferential surface 22 has torque-transmitting cooperation with the inner circumferential surface of an axially directed flange 24 on the hub sleeve 14. As indicated in figures 3 and 4, the pallet bearing ring 20 is provided with pockets 26 in its inner circumferential surface. These pockets 26 include, as shown in Figure 3, cylindrical segment-shaped recesses 28. As shown in Figures 1 and 5, a pawl 30 is arranged in each pocket 28. The pawl 30 has a part 32 intended for engaging cooperation with a pawl ring, and also has a cylindrical segment-shaped storage part 34 with which the pawl is pivotally engaged in the cylindrical segment-shaped recess 28. The pawl is shown in more detail in figure 6. The pawl 30 is provided with a groove 36 which is limited by two side surfaces 36a, 36b and by a bottom surface 36c.

Palbærerringen 20 er videre på sin indre omkretsflate forsynt med langs omkretsen forløpende ribber 38. The pallet bearing ring 20 is further provided on its inner circumferential surface with ribs 38 running along the circumference.

Palene 30 holdes aksialt og radielt i utsparingene 28 vedThe pawls 30 are held axially and radially in the recesses 28 by

hjelp av en sirkulær fjærring 40, se figurene 1,2 og 5. Fjærringen 40 er opptatt i sporet 36 i palene 30 og ligger using a circular spring ring 40, see Figures 1, 2 and 5. The spring ring 40 is engaged in the groove 36 in the pawls 30 and lies

an mot sideflatene 36a,b og mot sporbunnen 36c. Fjærringen 40 ligger videre på sin høyre side, som sett i figur 2, an mot de i omkretsretningen forløpende ribber 38, slik at fjærringen 40 er sikret mot aksial bevegelse i retning mot høyre i figur 2. Palene 30 ligger med sine venstre aksiale ende-flater, som sett i figur 1, an mot en pal-anslagsflate 42 i navhylsen 14. På denne måten er palene 30 sikret mot bevegelse i retning venstre i figur 1, idet palen holdes igjen av anslags-flaten 42, og palene er også sikret mot bevegelse i retning høyre i figur 1, idet dette skjer ved hjelp av fjærringen 40 som hindres i å bevege seg mot høyre som følge av sitt anlegg mot ribbene 38. against the side surfaces 36a,b and against the track bottom 36c. The spring ring 40 lies further on its right side, as seen in Figure 2, against the ribs 38 running in the circumferential direction, so that the spring ring 40 is secured against axial movement in the direction to the right in Figure 2. The pawls 30 lie with their left axial ends surfaces, as seen in figure 1, against a pawl abutment surface 42 in the hub sleeve 14. In this way, the pawls 30 are secured against movement in the left direction in figure 1, as the pawl is held back by the abutment surface 42, and the pawls are also secured against movement in the direction to the right in figure 1, as this occurs by means of the spring ring 40 which is prevented from moving to the right as a result of its bearing against the ribs 38.

Fjærringen 40 er sikret mot rotasjon i forhold til navhylsenThe spring ring 40 is secured against rotation in relation to the hub sleeve

14 derved at et endeparti 40a er bøyet aksialt og går inn i et innhakk 44 mellom to ribber 38. 14 whereby an end part 40a is bent axially and enters a notch 44 between two ribs 38.

Som vist i figur 1 er et drivelement 46 montert på lagerdelen 12 ved hjelp av et kulelager 48. Dette drivelementet kan innbefatte flere kjedehjul og kan være montert på navakselen 10 ved hjelp av et ytterligere, ikke vist kulelager. Drivelementet 46 er forsynt med en palkrans 50, se figur 5. Palen 30 presses til inngrep med palkransen 50 under påvirkning av fjærringen 40 som ligger an mot sporbunnen 36c nær den venstre enden i figur 5, hvorved det tilveiebringes et dreiemoment i retning med urviseren på palen 30, slik at derved inngrepspartiet 32 trykkes til inngrepssamvirke med palkransen 50. As shown in Figure 1, a drive element 46 is mounted on the bearing part 12 by means of a ball bearing 48. This drive element can include several sprockets and can be mounted on the hub shaft 10 by means of a further, not shown, ball bearing. The drive element 46 is provided with a pawl collar 50, see figure 5. The pawl 30 is pressed into engagement with the pawl collar 50 under the influence of the spring ring 40 which rests against the track bottom 36c near the left end in figure 5, whereby a torque is provided in a clockwise direction on the pawl 30, so that thereby the engaging part 32 is pressed into engaging cooperation with the pawl collar 50.

Palbærerringen 20 kan fremstilles relativt enkelt ved hjelpThe pallet bearing ring 20 can be produced relatively simply by using

av koldpressing, smiing eller fortrinnsvis ved sintring, uten by cold pressing, forging or preferably by sintering, without

etterfølgende maskinering. Dette skyldes særlig det faktum at man nå har kunnet utelate det omløpende spor i innerflaten til palbærerringen 20. Under monteringen av delene kan palene 30 og fjærringen 40 monteres etter at palbærerringen 20 er satt inn i navhylsen 14. Det er imidlertid også mulig å sette palbærerringen 20 sammen med palene og fjærringen 40 før disse komponenter som en enhet bringes inn i navhylsen 14 derved at palbærerringen 20 presses inn. Denne sistnevnte monteringsmetode foretrekkes. Ribbene 38 ligger innenfor palenes 30 aksiale utstrekning,og den aksiale utstrekning av palbærerringen 20 er i hovedsaken lik den aksiale utstrekning for palene 30, slik at den totale aksiale utstrekning for enheten innbefattende palbærerringen 20 og palene 30 vil være så liten som mulig. subsequent machining. This is particularly due to the fact that it has now been possible to omit the circumferential groove in the inner surface of the bearing ring 20. During the assembly of the parts, the pawls 30 and the spring ring 40 can be mounted after the bearing ring 20 has been inserted into the hub sleeve 14. However, it is also possible to insert the bearing ring 20 together with the pawls and the spring ring 40 before these components as a unit are brought into the hub sleeve 14 by pressing the pawl bearing ring 20 in. This latter mounting method is preferred. The ribs 38 lie within the axial extent of the piles 30, and the axial extent of the pile bearing ring 20 is essentially equal to the axial extent of the piles 30, so that the total axial extent for the unit including the pile bearing ring 20 and the piles 30 will be as small as possible.

Fremstillingsomkostningene er lave som følge av det faktumManufacturing costs are low as a result of that fact

at palbærerringen 20 ikke krever maskinering.that the pallet bearing ring 20 does not require machining.

Navhylsen 14 og palbærerringen 20 kan betraktes som den første rotorenhet, mens drivelementet 46 kan betraktes som den andre rotorenhet. The hub sleeve 14 and the bearing ring 20 can be considered as the first rotor unit, while the drive element 46 can be considered as the second rotor unit.
