Intwasahlobo yeqabunga elingemuva elihlanganisiwe ithembisa ukuguquguquka okwengeziwe kanye nesisindo esincane.
Yisho igama elithi “intwasahlobo yeqabunga” futhi kukhona ukuthambekela kokucabanga ngezimoto zemisipha yesikole sakudala ezineziphetho ezingemuva ezingaqinile, ezigcwele inqola, ama-axle aqinile noma, ngokwemibandela yesithuthuthu, amabhayisikili angaphambi kwempi aneqabunga ngaphambili elimiswe ngaphambili.Nokho, manje sesibheke ukuvuselela umqondo wamabhayisikili e-motocross.
Eqinisweni, nakuba izinhlelo zokumiswa ezingcolile, ezindala zivame ukusebenzisa iziphethu zamaqabunga, intwasahlobo ngokwayo ayivamisile ukuba umthombo wokuntula kwabo ubunkimbinkimbi.I-Chevrolet's Corvette yasebenzisa iziphethu zamaqabunga aguquguqukayo ekumisweni okuzimele kusukela esizukulwaneni sesibili ngo-1963 kuze kube kwethulwa isizukulwane sesishiyagalombili ngo-2020, yamukela iziphethu zepulasitiki eziyinhlanganisela ezineqabunga elilodwa ngeminyaka yawo-'80s.Abadumile kangako, iVolvo isebenzisa iziphethu zeqabunga eziyinhlanganisela, eziphambanayo kumamodeli ayo akamuva ambalwa.Uma zisetshenziswa kahle, iziphethu zamaqabunga ezenziwe ngezinto zesimanje zingaba lula kunamakhoyili ensimbi, futhi kwezinye izimo kulula ukupakisha ukuma kwawo okude, okuyisicaba.Imithombo yamaqabunga ayinhlanganisela, enziwe ngocezu olulodwa kunamahlamvu anqwabelene emithombo yamaqabunga ensimbi evamile, iphinde igweme ukungqubuzana kwamaqabunga amaningi ahlikihla ndawonye, okwakungenye yezithiyo eziyinhloko zemiklamo emidala.
Imithombo yamaqabunga ivele kumabhayisikili e-motocross enkathini yesimanje ngaphambilini.I-crosser yefekthri ka-Yamaha ka-1992-93, i-YZM250 0WE4, yasebenzisa iqabunga elilodwa eliyinhlanganisela ngemuva, ingaphambili layo liboshwe ngaphansi kwenjini futhi ingemuva liboshwe ekuxhumekeni ngezansi kwe-swingarm, ukuze njengoba isondo langemuva liphakama, iqabunga laguquguquka ukuze hlinzeka ngokukhula.Umqondo wawuwukusula indawo lapho isiphethu sangemuva kanye ne-damper yayivame ukuhlala khona, okuvumela indlela eqondile yokungena enjini.I-compact, rotary damper nayo yafakwa futhi ibhayisikili laba ngumnqobi womjaho ngo-1992 nango-1993 ku-All-Japan Championship.
Idizayini yethu entsha, evezwe esicelweni selungelo lobunikazi esivela enkampanini yase-Austrian, ibhekisela ku-Yamaha futhi iveza izinzuzo ezifanayo mayelana nokupakisha, kodwa yamukela isakhiwo esihlukile.Njengoba kubonisiwe ezithombeni, sibeka iqabunga endaweni ecishe iqonde mpo, siqine ngokumelene nengemuva lenjini ukuze sisule isikhala esivame ukugcwaliswa i-coilover (ilungelo lobunikazi liyaqinisekisa ukuthi nakuba isithombe salo esiholayo sibonisa isistimu embozwe esithombeni i-motocrosser evamile, isiphethu sekhoyili esiboniswe esithombeni besingeke sibe khona).
Ingaphezulu naphansi kwentwasahlobo ngayinye iboshwe ngokuqinile ekupheleni kokuxhuma.Ukuxhuma okungaphezulu kugxunyekwe ngokuyisisekelo ohlakeni oluyinhloko lwebhayisikili, kuyilapho i-pivots engezansi yokuxhumanisa isuka kubakaki ngaphansi kwe-swingarm.Umphumela uba ukuthi, njengoba i-swingarm ihambela phezulu, kwethulwa ukugoba entwasahlobo yamaqabunga ayinhlanganisela.Ukwengeza ukulungiseka, ubude bokuxhumanisa okuphezulu bungalungiseka ngentambo yesikulufu neknobhu yokulungisa, okwenza kube lula ukukhuphula noma ukunciphisa ukulayisha kuqala kusistimu.
Ilungelo lobunikazi alibonisi i-damper yengemuva elingemuva kodwa umbhalo walo uqinisekisa ukuthi umswakama ovamile uzosetshenziswa ukulawula ukumiswa kwangemuva.Kodwa-ke, kuzodingeka ukuthi iminyene kakhulu kunokushaqeka kwangemuva okuvamile, noma ifakwe ngokuhlukile, ukuze ivumele i-KTM ukuthi isebenzise izinzuzo zentwasahlobo yamaqabunga, ehlobene kakhulu nesikhala esiyikhululayo.Ilungelo lobunikazi liphakamisa ukuthi lesi sikhala singasetshenziswa ukwenza izingxenye ze-powertrain njengebhokisi lomoya, i-intake tract, noma i-muffler, isibonelo, enkulu noma esebenza kahle kakhulu.Ukwengeza, idizayini ingavumela ukuguquguquka okwengeziwe kwesakhiwo kumabhayisikili e-motocross anamandla kagesi azayo.
Ngale kwezinzuzo zokupakisha, enye inzuzo yesistimu ukulungiseka kwayo.Ilungelo lethu lobunikazi libonisa ukuthi ukushintsha ubude noma ukuma kokuxhumanisa okubambe noma yikuphi ukuphela kwentwasahlobo kungashintsha kanjani ukuziphatha kokumiswa.Emfanekisweni owodwa (I-Fig.7 kulungelo lobunikazi), izinhlelo ezine ezihlukene ze-lever ziboniswa ukushintsha ukuziphatha kokumiswa kwangemuva: ukushintsha ukusuka kuzinga elikhuphukayo (7a) ukuya kusilinganiso esingaguquki (7b), kanye nokwehla kwamazinga entwasahlobo (7c no-7d).Lokho kuziphatha okuhluke kakhulu kufinyelelwa ngaphandle kokushintsha intwasahlobo ngokwayo.
Njengakuqala, isicelo selungelo lobunikazi akusona isiqinisekiso sokuthi umbono uzofinyelela ekukhiqizweni, kodwa izinzuzo zokupakishwa kweqabunga elingemuva lentwasahlobo lingase libe yigugu kakhulu, ikakhulukazi esikhathini esizayo njengoba izitimela zikagesi ziphoqa onjiniyela ukuthi bacabange kabusha izakhiwo ezivamile eziye zacijwa ngesikhathi ikhulu lamabhayisikili enjini ye-piston.
