'ff' i I 'I i i i i' i I Description of a preferred: rgitförforms gg l _ ._ _ The one-way coupling shown in Fig. 1 comprises: three coaxial layer parts, viz In one inner sleeve 1, a coupling member 2 and an outer sleeve 3. The inner inner sleeve. l when the drive sleeve of the coupling, for example, is not shown shown drive shaft, the outer sleeve 3gatt may be the driven sleeve, which can only driven in one direction of rotation, as indicated by an arrow gdärpâ, thank you whether the .design of the coupling organ 2. described below 2. h The coupling member 2 is shown in Figs. 2 and 3 and has the shape of a metal strip, 'For example, spring steel, given the number of punched, heavy-duty elements 4, förffädesviš evenly fördeiadeenläng; fbandei. nande: now ashamed desired length and is formed into a ring, as shown in Fig. 2, with a diameter corresponding to it inner sleeve 1; outer diameter; Thanks to the elasticity of the ribbon material the elements 4 _gnu ifatt .iskot substantially tangentially from the belt. The the ring thus created shall be securely attached to the interior. sleeve l on something in appropriate way. g g l g g e e i . The outer sleeve 3 is threaded. then on, dimensioning being such that the elements 4 thereby have to be bent slightly, so that a certain pressure exercised by. them on the 'inner surface of the outer sleeve,' called a drive surface 3 " drive surface rabbit preferably. be provided with double teeth or the like to ensure a correct engagement with the heavy-duty elements 14.

Vid vridning av den inre hylsan l eller den drivande hylsan in medurs riktningnenligt figl kommer även. den yttre .hylsan 3 eller drivna hylsanlatt vrida sig tack vare 'det kraftöverförande ingreppet mellan elementen 4' och drivytan 3”. vid vridning av denidfivnnde hylsan iii motsatt eller .moturjsi riktning kommer elementennli blott att fjädra' ner och glida den drivna hylsans 3 g drivyta 31' utan förmåga att överföra någon drivkraft, varför v resultatet blir att ingen vridning överför-still den drivna hylsan 3._ i I I resonemanget ovan har den inre hylsanÜl betraktats som drivande; med samma effekter 'som beskrivitslkanidgen yttre hylsan 3 vara drivande] och den inre hylsan 1 driven. i *i .a 'iii e448 493 ,3' :vidden-föredragna utföringsformen är bandet 2' mednelementen 4 fäst vid den inre hylsan l,fi vilket är jmest fördelaktigt, eftersom i detta fall elementen kommer attaskjuta ut tangentiellt genom bandets 2 innelåoende elastiçitet. Det skullesemellertid vara möjligt att åstadkomma elementen 4 på den yttre hylsansl 3 inre-omkrets; .Elementen 14 kan även utformas som integrerade delar av antingen -hylsan .2 eller 3, t.ex. utstansade ur själva hylsan. i i i i i i lJet börnoteras att uppfinningen ligger-Li den "speciella"konstruktionen hos kopplingsorganetfí och att konstruktionen hos hylsorna l och 3 kan variera inom vida gränser. Andra modifikationer är möjliga inom ramen för f de efterföljande patentkraven.When turning the inner sleeve 1 or the driving sleeve clockwise directional figl also comes. the outer sleeve 3 or driven sleeve plate turn thanks to the 'force-transmitting engagement between the elements 4' and drive surface 3 ”. when turning the denidfivnnde sleeve iii opposite or .moturjsi direction, the element will only spring down and slide the driven one the 3 g driving surface 31 'of the sleeve without the ability to transmit any driving force, so v the result is that no rotation transmits the driven sleeve 3._ in I In the above reasoning, the inner sleeve tube has been considered as driving; with the same effects' as describedlkanidgen outer sleeve 3 be driving] and it inner sleeve 1 driven. i * i .a 'iii e448 493 , 3 ' In the preferred embodiment, the band 2 'is attached to the middle elements 4 at the inner sleeve 1, fi which is most advantageous, because in this case the elements will project tangentially out through the inner closure of the belt 2 elasticity. However, it should be possible to provide the elements 4 on the outer sleeve stop 3 inner circumference; The elements 14 can also be designed as integral parts of either the sleeve .2 or 3, e.g. punched out of themselves sleeve. i i i i i i It is noted that the invention lies in the "special" construction of the coupling means fí and that the construction of the sleeves 1 and 3 can vary within wide limits. Other modifications are possible within the framework of f the following claims.
