Description

15 20 25 30 35 450 477 Figur l visar ett tvärsnitt av,ett fordons hjulupphängning och Figur 2 visar i en förstorad skala ett tvärsnitt av ett impuls- hjul och en tätningsring ingående i fordonets hjulupp- hängning. Figure 20 shows a cross section of a vehicle's wheel suspension and Figure 2 shows on an enlarged scale a cross section of an impulse wheel and a sealing ring included in the vehicle's wheel suspension.

Bifogade figur l visar ett fordons framhjulsupphängning. Denna inne- fattar en delvis visad spindel l utformad med en axeltapp 2, på vil-- ken ett hjulnav 3 är lagrande anordnat i tvâ koniska rullager 4. Till hjulnavet 3 är anfäst ett av fordonets hjul (ej visat) på i sig kon- ventionellt sätt. Mellan hjulnavet 3 och spindeln l är anordnad en axeltätning 5, vilken med en metallisk ytterring 6 är fastpressad i ett ringformat urtag 7 i hjulnavets 3 ena sidoyta. Ytterringen 6 innefattar två med varandra sammanpräglade metallringar 6, vilka till- sammans uppvisar en U-formad tvärsnittsform. Axeltätningen 5 innefattar även en innerring 8, som är fastpressad mot en pâ axeltappen 2 fast- pressad slitring 9. Innerringen 8 är utformad av ett elastiskt material och är i radiell riktning förstyvad med en förstärkningsring l0 av metall. En invändig läpp ll av innerringen 8 pressas under inverkan av en ringfjäder l2 radiellt utåt till tätande anliggning mot ytterringen 6, samtidigt som glidning mellan läppen ll och ytterringen 6 medgives.Attached figure 1 shows the front suspension of a vehicle. This comprises a partially shown spindle 1 formed with a axle pin 2, on which a wheel hub 3 is mounted in two conical roller bearings 4. To the wheel hub 3 is attached one of the wheels of the vehicle (not shown) on the cone itself. conventional way. Arranged between the wheel hub 3 and the spindle 1 is a shaft seal 5, which with a metallic outer ring 6 is pressed into an annular recess 7 in one side surface of the wheel hub 3. The outer ring 6 comprises two interconnected metal rings 6, which together have a U-shaped cross-sectional shape. The shaft seal 5 also comprises an inner ring 8, which is pressed against a wear ring 9 pressed onto the shaft pin 2. The inner ring 8 is formed of an elastic material and is stiffened in the radial direction with a reinforcing ring 10 of metal. An inner lip 11 of the inner ring 8 is pressed under the action of an annular spring 12 radially outwards to a sealing abutment against the outer ring 6, at the same time as sliding between the lip 11 and the outer ring 6 is allowed.

I enlighet med föreliggande uppfinning är vid ytterringens 6 sidoyta anfäst, exempelvis medelst ett flertal punktsvetsförband, ett impuls- hjul l3. Impulshjulet 13 är utformat som en ringformad metallskiva och är utformad med ett flertal axiella kuggar 15 på den mot spindeln l vända sidan. Vid montering har axeltätningen 5 inpressats i hjulna- vets 3 urtag 7 så att en radiellt utanför ytterringen 6 utstickande kant av impulshjulet 13 anligger mot en axiell sidoyta av hjulnavet 3.In accordance with the present invention, an impulse wheel 13 is attached to the side surface of the outer ring 6, for example by means of a plurality of spot welded joints. The impulse wheel 13 is designed as an annular metal disc and is formed with a plurality of axial teeth 15 on the side facing the spindle 1. During assembly, the axle seal 5 has been pressed into the recess 7 of the wheel hub 3 so that an edge of the impulse wheel 13 projecting radially outside the outer ring 6 abuts against an axial side surface of the wheel hub 3.

Fördelsvis är impulshjulets l3 axiella tjocklek åtminstone dubbelt så tjock som det plâtmaterial ytterringen 6 är tillverkad av. Impuls- hjulet l3 samverkar med en magnetisk givare l6 fast anordnad i ett ur- tag i spindeln l och ingår i ett arrangemang för avkänning av hjul- navets 3 och därmed även fordonshjulets individuella rotationshastig- het. Vid hjulnavets 3 rotation medbringas tätningens 5 ytterring 6 liksom det därtill anfästa impulshjulet l3. Därigenom kan givaren l6 avkänna den hastighet med vilken impulshjulets l3 kuggar 10 15 20 25 30 i 450 47.1 passerar och kan avge en mot rotationshastigheten proportione11 ut- signa1. Genom att impu1shju1et 13 är utformat som en skiva medgives att denna kan göras ti11räck1igt tjock och formstyv så att axie11a kast hos impu1shju1et kan hå11as på en 1åg nivå. För att givaren 16 med ti11räck1ig noggrannhet ska11 kunna avkänna kuggarna 15 är det nämiigen mycket viktigt att givaren 16 kan monteras ti11räck1igt nära impu1shju1et 13. I U Det uppfinningsen1iga arrangemanget medför vidare att impu1shju1et 13 kan fastmonteras utan att det upptager något extra utrymme i axie11 utsträckning. Genom att anfästningen av impu1shju1et 13 ti11 tätningen 5 göres genom förmontering säkerstä11es att impu1shju1et 13 erhå11er rätt 1oka1isering förutom att monteringen b1ir enke1.Advantageously, the axial thickness of the impulse wheel 13 is at least twice as thick as the sheet material the outer ring 6 is made of. The impulse wheel 13 cooperates with a magnetic sensor 16 fixedly arranged in a recess in the spindle 1 and is included in an arrangement for sensing the wheel rotation hub 3 and thus also the vehicle wheel's individual rotational speed. When the wheel hub 3 rotates, the outer ring 6 of the seal 5 as well as the impulse wheel 13 attached thereto are carried. Thereby, the sensor 16 can sense the speed at which the teeth of the impulse wheel 13 pass in 450 47.1 and can emit a signal proportional to the rotational speed. Because the impulse wheel 13 is designed as a disc, it is admitted that it can be made sufficiently thick and rigid so that axial throws of the impulse wheel can be maintained at a low level. In order for the sensor 16 to be able to sense the teeth 15 with sufficient accuracy, it is namely very important that the sensor 16 can be mounted sufficiently close to the impulse wheel 13. The arrangement according to the invention further means that the impulse wheel 13 can be mounted without taking up extra space in the shaft. By attaching the impulse wheel 13 to the seal 5 by pre-assembly, it is ensured that the impulse wheel 13 obtains the correct location in addition to the assembly being simple.

Tätningen 5 är bortsett från impu1shju1et 13 en standardartike1, som kan framstä11as i stora serier och ti11 en re1ativt 1åg kostnad. Även framstä11ningen av impu1shju1et 13 är både enke1 och bi11ig.The seal 5, apart from the impulse wheel 13, is a standard article which can be manufactured in large series and at a relatively low cost. The manufacture of the impulse wheel 13 is also both simple and inexpensive.

Sammantaget erhå11es så1edes en mycket enke1 och bi11ig 1ösning som ändock motsvarar högt stä11da krav på funktionssäkerhet. Arrangemanget medför även att någon särski1d bearbetning av hju1navet 3 ej erfordras.All in all, a very simple and inexpensive solution is thus obtained which nevertheless corresponds to high demands on functional safety. The arrangement also means that no special processing of the wheel hub 3 is required.

Om fordonet ej ska11 utrustas med någon rotationshastighetsgivare kan en konventione11t utformad tätning utan impu1shju1 1ikavä1 monteras.If the vehicle is not to be equipped with a rotational speed sensor, a conventionally designed seal without an impulse wheel can be fitted.

Inom ramen för efterfö1jande patentkrav kan uppfinningen med förde1 även utnyttjas och ti11ämpas annor1unda än vad som exemp1ifierats i ovanstående beskrivning. Sâ1unda kan exempe1vis uppfinningen utnytt- jas vid varje roterbart maskinelement som är roterbart lagrat re1ativt ett fast maskine1ement. Impu1shju1et kan i stä11et för att vara utformat med kuggar exempe1vis vara utformat med ett f1erta1 magneter.Within the scope of the appended claims, the invention can with advantage also be utilized and applied differently from that exemplified in the above description. Thus, for example, the invention can be used with any rotatable machine element which is rotatably mounted relative to a fixed machine element. Instead of being formed with teeth, the impulse wheel can, for example, be formed with a pair of magnets.
