Description

7812583-s 2 I en nästa justerposition, c, c' med dämpkraften ci gäller samma sak som vid b, b' med den ursprungliga dämpkraften bi. Antalet justerpositíoner kan väljas godtyckligt. 7812583-s 2 In a next adjusting position, c, c 'with the damping force ci, the same applies as for b, b' with the original damping force bi. The number of adjustment positions can be selected arbitrarily.

Anordningen enligt uppfinningen möjliggör en mera progressiv justering, d .rus , en större ökning av dämpkraften vid ökande hastigheter än tidigare kända anord- ningar. Det kan konstateras att om samma starka dämpkraft vid samma bög-f: kolvhastighet skulle väljas vid tidigare kända anordningar sku-lie dërrnrf-zra:“':-n vid låga kolvhastigheter stiga mer än proportionellt.The device according to the invention enables a more progressive adjustment, i.e., a greater increase in the damping force at increasing speeds than previously known devices. It can be stated that if the same strong damping force at the same gay-f: piston speed were to be selected in previously known devices, it would rise more than proportionally at low piston speeds.

Enligt en utföringsform av uppfinningen visad i figurerna 2 och 3 beteclavar ° en. dämpmediefylld cylinder 7 där en kolv 2 med en kolvstöng 3 är förskjutna”. anordnad. Kolvstången 3 skjuter ut genom cylinderlocket 4, kolven 2 clelar cylindern l i två rum 5 och 6 och är försedd med passager 7, vilka kan ffšrbífäa de båda rummen och vilka, när stötdämparen intar viloläge , är stšlngflc: av M. ringformig eftergivlig ventil 8 på den sida som vetter mot cylinderrurnmet G .According to an embodiment of the invention shown in Figures 2 and 3, the clavicle. damping medium-filled cylinder 7 where a piston 2 with a piston rod 3 are displaced ”. arranged. The piston rod 3 projects through the cylinder cover 4, the piston 2 separates the cylinder into two chambers 5 and 6 and is provided with passages 7, which can bypass the two chambers and which, when the shock absorber enters rest position, are closed by M. annular resilient valve 8 on the side facing the cylinder tube G.

I* Passagernas 7 inlopp i cylinderrummet S kan stängas av ett reglerorgan ~.- , vilket för detta ändamål har en Sektion 10 med större diameter. rgartet '7 är också försett med en justerläpp ll, medan en justerklack 12 är anordnad i cylinderlocket 4.The inlet of the passages 7 in the cylinder space S can be closed by a control member ~ .-, which for this purpose has a section 10 of larger diameter. The device '7 is also provided with an adjusting lip 11, while an adjusting lug 12 is arranged in the cylinder cover 4.

Anordningens funktion är följande: Vid utåtgöende rörelse hos kolvstången 3 pressas dämpmedíum ut ur cylinder- rummet 5 genom passagerna 7 in i cylinderrummet 6. ventilen 8 öppnar. hfårvic* av dämpmediets tryck vid de passagers 7 utgångar, vars ingångar ej är :täckta av reglerorganet 9. Stängning av flera eller färre passager 7 ästadkomrnes genom att kolven 2 förs till ett ändläge vid cylinderlocket 4 varefter kolvstänqen 3 vrids så att justerläppen ll stöder mot justerklacken l2 och hindrar regler- organet 9_frän att ytterligare rotera och täcka ett större eller mindre antal passager 7 när kolvstängen 3 vrids ytterligare .The function of the device is as follows: During outward movement of the piston rod 3, damping medium is forced out of the cylinder space 5 through the passages 7 into the cylinder space 6. the valve 8 opens. The pressure of the damping medium at the outlets of the passages 7, the inputs of which are not: covered by the control means 9. Closure of more or fewer passages 7 is effected by moving the piston 2 to an end position at the cylinder head 4, after which the piston rod 3 is rotated so that the adjusting lip 11 supports the adjusting lug 12 and prevents the control member 9 from further rotating and covering a larger or smaller number of passages 7 when the piston rod 3 is turned further.
