Kort beskrivning av ritningen Nedan beskrivs uppﬁnningen närmare i anslutning till utföringsexempel samt bifo- gade ritning, där - Fig. l schematiskt visar en axiell vy av en första uttöringsforrn av ett arrangemang enligt uppfinningen samt - Fig. 2 schematiskt visar ett arrangemang väsentligen enligt ﬁg. 1 sett från höger i ﬁg. 1.Brief description of the drawing The invention is described in more detail in connection with exemplary embodiments and the accompanying drawing, in which - Fig. 1 schematically shows an axial view of a first embodiment of an arrangement according to the invention and - Fig. 2 schematically shows an arrangement substantially according to ﬁ g. 1 seen from the right in ﬁ g. 1.

Detaljerad beskrivning av föredragna utfóringsforiner I ﬁgurema betecknas med l en huvudaxel hos en manuell växellåda och med 2 ett vid huvudaxeln anordnat huvudaxelhjul. Med 3 betecknas en sidoaxel hos växellå- dan där de båda axlarna l, 3 vanligen är sinsemellan parallella. Mellan axlarna l, 3 är ett backmellanhjul 4 anordnat att verka via åtminstone ett axelhjul 2, där back- mellanhjulet är anordnat att vara i ingrepp intermittent.DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS The ﬁ gures are denoted by 1 a main shaft of a manual gearbox and by 2 a main shaft wheel arranged at the main shaft. 3 denotes a side shaft of the gearbox where the two shafts 1, 3 are usually parallel to each other. Between the axles 1, 3, a reversing intermediate wheel 4 is arranged to act via at least one axle wheel 2, where the reversing intermediate wheel is arranged to be engaged intermittently.

För lagring och uppbärande av backmellarihjulet fórefinns anordningar 5, vilka upp- bäres av huvudaxeln och sidoaxeln. Enligt den visade utfóringsforrnen är baclcmel- lanhjulet via tappar 6 eller en hjulaxel 7 lagrat i och anordnat mellan tvenne bär- stycken 8, vilka är lagrat påtörda huvudaxeln och sidoaxeln såsom schematiskt visas i t.ex. ﬁg. 2. Lager betecknas i ﬁgurema allmänt med 9 och visas i ﬁg. 2 som ett i skärningen mellan inbördes lagrade element. ..o nu en n . 10 15 20 525 411 3 Föredraget är också att sagda anordningar, bärstyckena 8, är anordnade att upptaga åtminstone en del av mellan huvudaxeln och sidoaxeln verkande laster och därvid att motverka utböjning av axlarna tvärs deras axiella riktning.For storage and support of the reversing wheel there are devices 5, which are supported by the main shaft and the side shaft. According to the embodiment shown, the rear center wheel is mounted via pins 6 or a wheel shaft 7 in and arranged between two support pieces 8, which are mounted on the main shaft and the side shaft as schematically shown in e.g. ﬁ g. 2. Layers are denoted in ﬁ gurema generally by 9 and shown in ﬁ g. 2 as an element in the intersection between mutually stored elements. ..o nu en n. It is also preferred that said devices, the support pieces 8, are arranged to receive at least a part of loads acting between the main shaft and the side shaft and thereby to counteract deflection of the shafts across their axial direction.

Sättet liksom funktionen hos anordningen enligt uppfinningen torde till väsentlig del framgått ovan.The method as well as the function of the device according to the invention should to a substantial extent appear above.

Backmellarilijulet lagras således i och uppbäres medelst sagda anordningar 5, bärstyckena 8, varigenom hjulet ej är i kontakt med växellådshuset. Därmed är en ljudtransrriissionsväg bruten, varigenom backmellanhjulets bidrag till den totala ljudnivån kraftigt minskar eller helt elimineras. Enligt det visade utförandet, vilket är föredraget, sammanhålles huvudaxeln och sidoaxeln av sagda anordningar 5, bärstyckena 8, i en lagrad konﬁguration, varvid axlarna hâlles på ett bestämt inbör- des avstånd, och inbördes utböjning sålunda förhindras.The rear intermediate wheel is thus stored in and supported by said devices 5, the support pieces 8, whereby the wheel is not in contact with the gearbox housing. Thus, a sound transmission path is broken, whereby the contribution of the rear intermediate wheel to the overall sound level is greatly reduced or completely eliminated. According to the embodiment shown, which is preferred, the main shaft and the side shaft of said devices 5, the support pieces 8, are held together in a stored configuration, the shafts being kept at a certain mutual distance, and mutual deflection is thus prevented.

Ovan har uppﬁnningen beskrivits i anslutning till uttöringsexempel och föredragna utföringsformer. Naturligtvis kan fler utföringsfonner liksom mindre förändringar och kompletteringar tänkas utan att den grundläggande uppñnningstanken frångås.The invention has been described above in connection with desiccation examples and preferred embodiments. Of course, more embodiments as well as minor changes and additions are conceivable without departing from the basic idea of invention.

Sålunda kan olika arrangemang tänkas för att hålla anordningarna 5, bärstyckena 8, ñxerade i axlamas axiella riktning samt inbördes. Detta kan ske medelst lagringen på axlarna och/eller medelst backmellanhjulets lagring. En separat förbindning (ej visad) bärstyckena emellan kan också Lagringen av bärstyckena på axlarna och lagringen av backmellanhjulet kan företrä- desvis ske medelst spårkullager men andra lagertyper kan tänkas.Thus, different arrangements are conceivable for keeping the devices 5, the support pieces 8, axed in the axial direction of the shafts and with each other. This can be done by means of the bearing on the axles and / or by means of the bearing between the rear intermediate wheel. A separate connection (not shown) between the support pieces can also be made.

Uppﬁnningen skall således ej anses begränsad till ovan angivna utföranden utan kan varieras inom sin av bifogade patentkrav angivna ram. 22 - s f: anna IThe invention shall thus not be considered limited to the above-mentioned embodiments but may be varied within its scope specified by the appended claims. 22 - s f: anna I
