Saddex dhululubo

Maxaa dhacaya haddii ay ahayd mooto ENGINE heer sare ah?

Waagii hore waxaan u naqaannay 3-cylinder 2-stroke, online on Kawasaki, Suzuki iyo Motobécane, ama V-qaabeeya Honda. Dhab ahaantii, Honda, kuwanu waxay ahaayeen matoorada toosan, oo dhululubada kuwaas oo la soo dejiyey si ay u helaan ballac. Manequinkiiba waxa jiray hal ushii isku xidha, dhululubo kastana waxa uu lahaa daasad bamka oo madax banaan. Matooradan waxaa lagu qalabeeyay 400 oo PSA ah oo waddo ah iyo 500 RS iyo NS GPs. Faahfaahin qosol leh, qaab-dhismeedka la isticmaalay waa la rogay: 2 dhululubo siman iyo mid toosan oo waddada ah, liddi ku ah GP-ga. Malaha arrimaha la xidhiidha marinka dheryaha nasashada iyo kulaylka la sii daayay ...

Marka la soo koobo, matoorada saddex-dhululubo ah ayaa maalmahan waa matoorada dabaysha ku jirta shiraacyadooda, laakiin dhammaantood waxay leeyihiin qaab-dhismeedka isku mid ah: mishiinka khadka dhexda ah iyo dabcan wareegga 4-stroke, sababtoo ah laba-stroke mar dambe dabayshu kuma jirto. shiraaciisa...

Mid ka mid ah dhammaan, dhammaan online!

Si loo hagaajiyo qaabaynta ugu fiican marka la eego gariir iyo joogteynta meertada, kiishku waxa la dhigayaa 120 ° kasta si loo sameeyo hawlgal joogto ah, gubanaya 240 ° kasta (hal leexasho / 2). In 70s / 80s Laverda sii daayay 180 ° saddex-dhululubo 1000, engine kaas oo ahaa wax ka badan "sifo" ka badan versions raacay 120 °. Baabuurkan, oo loogu magac daray "Jota" ka dib mid Isbaanishka saddex-stroke, ayaa weli ah mid ka reeban.

4-saddex-dhululubo oo istaroog ah GP-ga

Matoorka saddex-dhululubo ayaa sidoo kale si cajiib ah ugu fiicnaa GP-ga, marka hore 4 tallaabo, xilligii MV Agusta ee sharafta lahaa, ka dibna 2 tallaabo. Waqtigeedii hore waa mid aad u ammaan badan xitaa maanta 800 F3 waxaa iska leh MV3 350 (1965) iyo 500 (1966). 500 horumaray oo ku saabsan 80 hp. 12 rpm oo dhaafiyay 000 km/h. Waxay ku guuleysatay ugu yaraan 270 koob oo adduunka ah intii u dhaxaysay 6 iyo 1966 ee gacmaha Giacomo Agostini! Haddii mishiinnada farsamada gacanta ay la wareegaan qaab-dhismeedkan qadiimiga ah, matoorada casriga ahi waxay leeyihiin shaadh-wareeg-wareejin ah oo yaraynaysa saamaynta gyroscopic ee mootada oo kor u qaadaysa awooddeeda.

Waxaan dhawaan aragnay GP-ga saddex-dhululubo ah mar kale intii lagu jiray hagaajinta afarta-stroke. Sannadkii 2003, si kastaba ha ahaatee, oo loo ekeysiiyay sida Aprilia Cube, aad bay uga qancisa yaraa VM-ka. Dhab ahaantii, habkani waxa uu isku daraa cidhiidhi qaraabo ah iyo awoodda is-beddelka sidaas awgeedna waxa uu kobciyaa awoodo gaar ah oo aad u weyn. "Marka la eego" waxay u badan tahay inay tahay qayb ka mid ah dhibaatada Kuuba, sababtoo ah hadda waa inaad gaarto xawaare aad u daran si aad naftaada ugu dirto GP-gaaga.

Qaababka aan la socon karin dhismooyinka aan si ku filan u kala saarin barokaca. Tani waxay ciqaabaysaa xawaaraha tooska ah ee piston-ka, sida aan ka hadli doono dambe. Iyadoo 88,6 X 53,5 feeraha "lagu dhawaaqay", cube wuxuu ku dhibtooday inuu dhaafo 15 rpm. Cuntadu aad bay u yar tahay, oo leh kala duwanaansho cidhiidhi ah. Natiijadu waxay ahayd matoor naxariis daran oo xannibay qabsashada iyo sahlanaanta wadista.

U dhigma

Sababtaas awgeed, qaybta supersport-ka, sida SBK, saddexda dhululubada ayaa faa'iido u leh inay ka sarreeyaan 4 dhululubo. Markaa waxaanu aragnay istaroogga 675 cc ee MV saddex dhululubo iyo Triumph oo ka soo horjeeda 3 cc 600 cylinder. Gudaha SBK inta lagu jiro 3 4-dhululubo, 750 saddex-dhululubo ah iyo 4-dhululubo mataano ah. Tani waxay u ogolaatay Petronas in ay isticmaasho 900 oo xiiso leh oo leh matoor rogan: rogan (daalku xagga dambe, albaabka hore iyo dhululubada gadaal u janjeera). Tusaale wanaagsan oo ah "saddex lugood".

Xeerka dulqaadashadu waa 600 afar dhululubo, laakiin saddex dhululubo waa lagama maarmaan in la dhaafo 750 cm3. Kala duwanaansho aan laga helin GP-ga, gaar ahaan maanta, marka xeerarku dejiyaan ugu badnaan 4 dhululubo iyo boodh aan ka badnayn 81mm. Dhab ahaantii, cabbirada GP-ga saddex-dhululubo ah, oo sida ugu fiican loo hagaajin karo, waxay noqon doonaan 81 x 48,5 mm ama xawaraha ugu badan ee ku saabsan 17 rpm ee xawaaraha toosan ee piston ee 000 m / s. Marka lagu daro awoodda faras ee ugu badan, malaha wax yar oo cadaalad ah, waxaa jira xirmo aad u degdeg badan oo laga digtoonaado, oo aan ku habboonayn tirada matoorada ee la oggol yahay xilli kasta. Markaa, marka laga reebo raadinta dhibaatooyinka, qofna ma shaqaaleysiin doono saddexda-dhululubo ilaa ogeysiis dambe.

Yar laakiin xoog badan

Marka ay timaado tartanka wadooyinka iyo isboortiga, seddexleyda ayaa iska indhatira arrimahan. Waxa uu ku ciyaaraa isafgaradkiisa (800 MW kaliya ayaa miisaankiisu yahay 52 kg!) Si loogu adeego mootooyinka had iyo jeer aad u xiiso badan iyada oo ay uga mahadcelinayaan habayntiisa, taas oo siinaysa jawaab celin aad u fiican iyo joogitaanka dhabta ah. Tan waxa caddaynaya qalloocyada buug-gacmeedka injiinka ee caanka ah. Marka hore, waxaanu ogaanay wareegtada degdega ah ee 1616cc (3 X 3cc) ee mishiinka saddex-dhululubo ah.

Waxaa jira heerar ugu sarreeya oo ah 603 Nm, halka qalooca soo socda 4 dhululubada 2155 (4 X 538 cm3), si kastaba ha ahaatee horumariya wareegga celceliska sare (180 Nm oo ka soo horjeeda 135), waxay leeyihiin kaliya 425 Nm oo ah qulqulka ugu sarreeya ee degdegga ah. !

Marka la soo koobo, barokaca hoose iyo qulqulka dhexda hoose, saddexda-dhululubo ee dareemaha degdega ah ayaa aad uga sarreeya mishiinka 4-dhululubo, taas oo macnaheedu yahay farxad dheeraad ah oo loogu talagalay duuliyaha.

gunaanad

Haddi ay tahay fuusha dariiqa, baabuurka ama fuusha gaadhiga ciyaaraha, waa mishiin soo jiidasho leh oo ka yar kana fudud afar-dhululubo. Tayada isaga u ballanqaadaya mustaqbal ifaya oo ku saabsan laba ama afar taayir. Runtii, si tartiib tartiib ah ayaa sidoo kale lagu soo rogayaa daboolka gawaarida casriga ah ee noocyada leh awood weyn oo ah 1000 ama 1200 cm3. Go'aansan, ma uu dhammaysan yaab nagu!
