Composite rear leaf spring inovimbisa kuwedzera kuchinjika uye huremu hushoma.

Taura izwi rekuti “chitubu chemashizha” uye pane katsika kekufunga nezvemotokari dzechikoro chekare dzine mhasuru dzisina kusimba, dzakasimukira, dzakasimba-ekisero kumashure kana, mumashoko emudhudhudhu, mabhasikoro asati atanga hondo ane mashizha echirimo pamberi.Nekudaro, isu tave kutarisa kumutsiridza iyo pfungwa yemotocross bhasikoro.

Muchokwadi, nepo zvisina kunaka, masisitimu ekare ekumisikidza aiwanzo shandisa zvitubu zvemashizha, chitubu pachacho hachiwanzo bviro yekushaikwa kwavo kwehunyanzvi.Chevrolet's Corvette yakashandisa zvitubu zvemashizha zvakachinjika pakumiswa yakazvimiririra kubva kuchizvarwa chechipiri muna 1963 kusvika pakuvambwa kwechizvarwa chechisere muna 2020, vachitora zvitubu zvepurasitiki zvine shizha rimwe muma'80s.Zvisina mukurumbira, Volvo inoshandisa akaumbwa, anochinjika mashizha zvitubu mune akati wandei emhando dzazvino.Zvichishandiswa nemazvo, zvitubu zvemashizha zvakagadzirwa nemidziyo yemazuva ano zvinogona kureruka pane makoiri esimbi, uye mune dzimwe nguva chimiro chavo chakareba, chakati sandara chiri nyore kurongedza.Zvitubu zvemashizha akaumbwa, akagadzirwa nechidimbu chimwe chete kwete mashizha akaturikidzana ezvitubu zvesimbi zvechinyakare, zvinodzivirirawo kupokana kwemashizha akawanda achikweshana pamwe chete, icho chaiva chimwe chezvipingamupinyi zvikuru zvemagadzirirwo ekare.
Zvitubu zvemashizha zvakaonekwa pamotocross bikes munguva yemazuva ano zvisati zvaitika.Yamaha's 1992-93 fekitori 'crosser, iyo YZM250 0WE4, yakashandisa shizha rimwechete rakaumbwa kumashure, kumberi kwaro kwakasungirirwa pasi peinjini uye yekumashure yakavharirwa kune chinongedzo pazasi pe swingarm, zvekuti vhiri rekumashure paraisimuka, shizha raichinjika kupa chitubu.Pfungwa iyi yaive yekubvisa nzvimbo iyo chitubu chekumashure uye damper yaiwanzogara, ichibvumira nzira yakatwasuka yeinjini.A compact, rotary damper yakaiswa zvakare uye bhasikoro raive rakahwina mujaho mune zvese 1992 na1993 muAll-Japan Championship.
Dhizaini yedu nyowani, yakaratidzwa mune patent application kubva kuAustria kambani, inoreva iyo Yamaha uye inonongedza mabhenefiti akafanana maererano nekurongedza, asi inotora imwe dhizaini.Sezvinoratidzwa mumifananidzo, tinoisa shizha munzvimbo yakatwasuka, yakasimba kumberi kweinjini kujekesa nzvimbo inowanzozadzwa necoilover (iyo patent inosimbisa kuti nepo mufananidzo wayo unotungamira unoratidza sisitimu yakafukidzwa pamufananidzo we yakajairwa motocrosser, iyo coil chitubu inoratidzwa mumufananidzo yaisavepo).

Pamusoro uye pasi pechitubu chimwe nechimwe chakasungirirwa zvakasimba kusvika kumagumo ekubatanidza.Iyo yekumusoro yekubatanidza inoiswa pivotally pahombe yebhasikoro, nepo yepasi yekubatanidza pivots kubva pachibhuraketi pasi pe swingarm.Mhedzisiro ndeyokuti, sezvo swingarm inofamba ichikwira kumusoro, bend inounzwa kune inoumbwa mashizha chitubu.Kuti uwedzere kugadzirika, kureba kwekumusoro kwekubatanidza kunogadziriswa kuburikidza nescrew thread uye inogadzirisa knob, zvichiita kuti zvive nyore kuwedzera kana kuderedza preload muhurongwa.Iyo patent hairatidze damper yekumashure kumagumo asi zvinyorwa zvayo zvinotsigira kuti yakajairwa damper yaizoshandiswa kudzora kumisa kumashure.Nekudaro, yaizofanira kunge yakanyatso compact pane yakajairwa kumashure kuvhunduka, kana kuisirwa zvakasiyana, kubvumira KTM kutora mukana wezvakanakira shizha chitubu, icho chine hukama zvakanyanya nenzvimbo yainosunungura.Iyo patent inoratidza nzvimbo iyi inogona kushandiswa kugadzira zvikamu zvemagetsi senge airbox, turakiti rekutora, kana muffler, semuenzaniso, hombe kana kunyatsoshanda.Pamusoro pezvo, dhizaini yacho inogona kubvumira kuchinjika kwemaitiro mune ramangwana remagetsi-powered motocross bikes.

Kupfuura mabhenefiti ekurongedza, imwe bhenefiti yehurongwa ndeyekugadziriswa kwayo.Patent yedu inoratidza kuti kushandura kureba kana chimiro chezvinongedzo zvakabata chero magumo echirimo zvinogona kushandura maitiro ekumisa.Mune mumwe mufananidzo (Fig.7 mune patent), mana akasiyana marongero erevheti anoratidzwa kuti achinje maitiro ekusimudzwa kwemashure: kuchinja kubva pakukwira (7a) kusvika kuchiyero chenguva dzose (7b), uye kuderera kwemitengo yechirimo (7c uye 7d).Aya maitiro akasiyana zvakanyanya anowanikwa pasina kushandura chitubu pachacho.
Sekare, kunyorera patent hakusi vimbiso yekuti zano richasvika mukugadzirwa, asi kurongedza kwakanakira kweshizha chitubu kumashure kwekupedzisira kunogona kuwedzera kukosha, kunyanya mune ramangwana sezvo magetsi emagetsi anomanikidza mainjiniya kuti afunge zvakare marongero akajairwa akakwenenzverwa panguva zana remakore remabhasikoro einjini-piston.
