Description

467 573 2 10 15 20 25 30 35 Detta uppnås enligt uppfinningen genom att backkugghjulet är låsbart på sin axel enbart medelst en konisk koppling. 467 573 2 10 15 20 25 30 35 This is achieved according to the invention in that the reverse gear is lockable on its shaft only by means of a conical coupling.

Uppfinningen bygger på att de moment som normalt uppträder vid backning är så pass låga, att det räcker med en enkel konisk koppling vars inkopplingskraft företrädesvis åstadkommas me- delst hydraultryck, för att låsa backkugghjulet på sin axel.The invention is based on the elements that normally occur at backing is so low that a simple cone is sufficient coupling whose coupling force is preferably provided by means of partly hydraulic pressure, to lock the reverse gear on its shaft.

Genom att eliminera en kopplingshylsa med formbundet ingrepp med samverkande kopplíngselement undanröjes risken för låsning orsakad av momentomvandlarens ingående moment.By eliminating a coupling sleeve with form-fitting engagement with cooperating coupling elements the risk of locking is eliminated caused by the input torque of the torque converter.

Uppfinningen beskrives närmare nedan under hänvisning till på bifogade ritning visade utföringsexempel, där fíg 1 visar en schematísk ändvy av en växellåda enligt och fíg 2 en schema- tísk längdsektion utefter linjen I-I i fig 1.The invention is described in more detail below with reference to on the accompanying drawing shows exemplary embodiments, in which Fig. 1 shows a schematic end view of a gearbox according to and fig. 2 a schematic longitudinal section along the line I-I in Fig. 1.

Den i figurerna visade växellådan är en femväxlad automat- växellåda avsedd för bakhjulsdrift. växellådan har-ett hus 1 med en ingående axel 2, som är driven av en icke visad motor via en konventionell hydraulisk moment- omvandlare 3. Den ingående axeln 2 uppvisar ett par ovridbart på axeln fixerade drivkugghjul 4 och 5, som står i ingrepp med ett par på en första mellanaxel 6 och en andra mellanaxel 7 roterbart lagrade kugghjul 8 resp 9. vilka är låsbara på sina respektive axlar medelst första och andra flerskiviga våt- lamellkopplingar 10 resp 11.The gearbox shown in the figures is a five-speed automatic gearbox intended for rear-wheel drive. the gearbox has a housing 1 with an input shaft 2, which is driven of a motor (not shown) via a conventional hydraulic torque transducer 3. The input shaft 2 has a pair of non-rotatable drive gears 4 and 5 fixed on the shaft, which engage with a pair on a first intermediate shaft 6 and a second intermediate shaft 7 rotatably mounted gears 8 and 9, respectively, which are lockable on theirs respective shafts by means of first and second multi-disc wet lamella couplings 10 and 11 respectively.

Den ingående axeln 2 uppvisar ytterligare ett på axeln ovrid- bart fixerat kugghjul 12. som ingriper med var sitt på respek- tive mellanaxel 6, 7 roterbart lagrat kugghjul 13 och 14, vil- ka är låsbara på sina axlar av tredje och fjärde flerskiviga våtlamellkopplingar 15 och 16. Respektive mellanaxel driver en utgående axel 17 via ett med resp axel ovridbart förbundet kugghjul 18 och 19. som står i ingrepp med ett via en envägs- koppling 20 på den utgående axeln lagrat första kugghjul 21 och ett på axeln ovridbart fixerat kugghjul 22. Envägskopp- 10 15 20 25 30 35 3 467 573 lingen 20 kan låsas medelst en flerskivig våtlamellkoppling 23 och de ingående och utgående axlarna kan låsas samman av en flerskivig våtlamellkoppling 25.The input shaft 2 has a further shaft rotating on the shaft. fixed gear 12. which engages with each other on the gear shaft 6, 7 rotatably mounted gears 13 and 14, which ka are lockable on their shoulders of third and fourth multi-disc wet lamella couplings 15 and 16. Each intermediate shaft drives one output shaft 17 via a shaft rotatably connected to the respective shaft gears 18 and 19. which engage with one via a one-way clutch 20 on the output shaft mounted first gear 21 and a gear wheel non-rotatably fixed to the shaft 22. One-way clutch 10 15 20 25 30 35 3 467 573 The ring 20 can be locked by means of a multi-disc wet lamella coupling 23 and the input and output shafts can be locked together by one multi-disc wet lamella coupling 25.

Pâ mellanaxeln 6 är ett kugghjul 26 lagrat för rotation till- sammans med kugghjulet 8. Kugghjulet 26 står i ingrepp med ett backkugghjul 27, vilket är fritt roterbart lagrat på axeln 7 samt låsbart på axeln 7 av en generellt med 28 betecknad ko- nisk koppling, som innefattar en med en axiellt förskjutbar ringformig hydraulkolv 29 förbunden kopplingskona 30. Mellan kolven 29 och ett ringformigt, med axeln 7 fast förbundet cy- linderelement 31 avgränsas en ringformig kammare 32 och vid tillförsel av tryckolja till kammaren 32 förskjutes kolven 29 axiellt, varvid dess kopplingskona 30 bringas i ingrepp med en komplementär kopplingskona 33, som är fast förbunden med back- kugghjulet 26, så att detta låses på mellanaxeln 7.On the intermediate shaft 6, a gear 26 is mounted for rotation to together with the gear 8. The gear 26 engages with one reverse gear 27, which is freely rotatably mounted on the shaft 7 and lockable on the shaft 7 of a generally designated 28 mechanical coupling, which comprises one with an axially displaceable annular hydraulic piston 29 connected coupling cone 30. Between piston 29 and an annular cylinder fixedly connected to the shaft 7 relief element 31 delimits an annular chamber 32 and at supply of pressure oil to the chamber 32 displaces the piston 29 axially, its coupling cone 30 being brought into engagement with a complementary coupling cone 33, which is fixedly connected to the reverse gear 26 so that it locks on the intermediate shaft 7.

Växlíngen i den beskrivna växellådan styrs av ett icke visat elektroniskt, mikroprocessorreglerat styrsystem. som påverkar ett hydrauliskt manöversystem (icke visat), vilket reglerar till- och frånslag av respektive kopplingar.The gearbox in the described gearbox is controlled by one not shown electronic, microprocessor-controlled control system. that affects a hydraulic control system (not shown), which regulates switching on and off of the respective connections.

På de olika växlarna överföres momentet från ingående till ut- gående axeln enligt följande: Ettan) Kugghjulsparet 4, 8 tillslagen koppling 10, kugghjuls- paret 18, 21 och frihjulskopplingen 20; Tvåan) Kugghjulsparet 5, 9, tillslagen koppling 11 och kugg- hjulsparet 19, 22: Trean) Kugghjulsparet 12, 13. tillslagen koppling 15, kugg- hjulsparet 18, 21 och frihjulskopplingen 20; Fyran) Kugghjulsparet 12, 14, tillslagen koppling 16 och kugg- hjulsparet 19, 22: Femman) Tillslagen koppling 25 (direktväxel); 467 573 4 Backen) Kugghjulsparet 4, 8, frikopplad koppling 10. kugg- hjulsparet 26, 27, tillslagen koppling 28 och kugghjulsparet 19, 22. 5 Genom uppfinningen åstadkommes en enkel tillförlitlig och kom- pakt konstruktion vid vilken växling till och från backväxeln åstadkommes utan risk för blockering och slag. 110At the various gears, the torque is transmitted from the input to the output walking shaft as follows: One) The gear pair 4, 8 clutch engaged 10, the gear the pair 18, 21 and the freewheel clutch 20; Second) Gear pair 5, 9, clutch engaged 11 and gear wheel pair 19, 22: Trean) Gear pair 12, 13. engaged clutch 15, gear the wheel pair 18, 21 and the freewheel clutch 20; Four) Gear pair 12, 14, clutch engaged 16 and gear wheel pair 19, 22: Five) Activated clutch 25 (direct gear); 467 573 4 Hill) Gear pair 4, 8, disengaged clutch 10. gear the wheel pair 26, 27, the engaged clutch 28 and the gear pair 19, 22.
