Chengetedzo kutanga, nyaradzo yechipiri
Zvigaro zvemota zvinonyanya zvinosanganisira akawanda akasiyana marudzi ezvikamu zvakaita semafuremu, zvimiro zvemagetsi, uye zvivharo zvefuro.Pakati pavo, chigaro chechigaro ndicho chinonyanya kukosha chikamu chekuchengetedza chigaro chemotokari.Zvakafanana neskeleton yemunhu, inotakura foam yechigaro, chivharo, zvikamu zvemagetsi, zvikamu zvepurasitiki nezvimwe zvikamu zvakafanana ne "nyama neropa".Icho zvakare chikamu chepakati chinotakura mutoro, inotumira torque uye inowedzera kugadzikana.
Iyo LIL mota dzakatevedzana zvigaro zvinoshandisa imwechete papuratifomu furemu seBBA, mota yemhando yepamusoro, uye Volvo, mhando inozivikanwa nekuchengetedzeka kwayo, ichiisa hwaro hwakanaka hwekuchengetedza chigaro.Kuita kwema skeletons aya kuri nani, asi hongu mutengo wakakwirawo.Iyo LI chigaro chemotokari R&D timu inotenda kuti zvakakodzera kubhadhara mutengo wakakwira kuti uve nechokwadi chekuchengetedza chigaro.Tinofanirawo kupa dziviriro inosimbisa kune vatinogara kunyange kwatisingaoni.
"Kunyangwe OEM yega yega yave kuvandudza kugarika kwezvigaro, uye LI yaita basa rakanaka panyaya iyi, tagara tichiziva kuti pane kumwe kupokana kwechisikigo pakati pekuchengetedza nekunyaradza, uye isu tinoda zvese Dhizaini inofanirwa kubva pane. kuchengeteka, uyezve funga kunyaradza, ”Zhixing akadaro.
Akatora anti-submarine chimiro chechigaro semuenzaniso.Sezvinoratidzwa nezita racho, basa remaitiro e-anti-submarine nderokuderedza ngozi yebhanhire rechigaro rinotsvedza kubva munzvimbo yepelvic richienda mudumbu reanogara kana kudhumhana kunoitika, zvichiita kuti kusvina kukanganisa kunhengo dzomukati.Izvi zvinonyanya kubatsira kuvakadzi uye nhengo diki dzevashandi, avo vanogona kunyura nekuda kwehukuru hwavo uye huremu.
Nemamwe mashoko, "Kana motokari yasangana nekudhumhana, muviri wemunhu unoenda kumberi pachigaro nekuda kwekushaya simba uye kunyura pasi panguva imwe chete. Panguva ino, kana pane anti-submarine danda pachigaro kuti ubate matako, anogona kudzivirira matako kufamba zvakanyanya "
Zhixing akati, "Tinoziva kuti dzimwe mota dzeJapan dzichaisa matanda emumutsara wepiri anopesana nepasi pemvura, kuitira kuti furo riite gobvu uye rwendo ruve rwakanaka, asi kuchengetedzwa kunofanirwa kukanganisika.Uye Kunyangwe iyo LI chigadzirwa ichitarisawo pakunyaradza, haizokanganise pakuchengetedza."
Chokutanga pane zvose, takanyatsofunga nezvesimba rakagadzirwa apo motokari yose yakabonderana, uye takasarudza EPP yakakura-yakakura (Yakawedzerwa polypropylene, rudzi rutsva rwepurasitiki yefuro ine basa rakanaka) sekutsigira.Isu takadzokorora kugadzirisa EPP mumataundi akawanda panguva yekuzoongororwa.Iyo dhizaini chinzvimbo, kuoma, uye density inodiwa kuti isangane neiyo crash test performance zvinodiwa.Zvadaro, takabatanidza kunyaradzwa kwechigaro kuti tipedze kugadzirwa kwechimiro uye dhizaini yezvimiro, kuve nechokwadi chekuchengetedzwa uku uchipa nyaradzo.
Mushure mekunge vashandisi vakawanda vatenga motokari itsva, vanowedzera zvinhu zvakasiyana-siyana zvekushongedza uye zvekudzivirira kumotokari yavo, kunyanya zvivharo zvezvigaro kuchengetedza zvigaro kubva pakupfeka uye mavara.Zhixing inoda kuyeuchidza vashandisi vazhinji kuti nepo mavhavha ezvigaro achiunza nyore, anogona kuunza njodzi dzekuchengetedza."Kunyange zvazvo chifukidziro chechigaro chiri chakapfava, chinoparadza chimiro chechimiro chechigaro, izvo zvinogona kukonzera kutungamira uye ukuru hwesimba pane varimo kuti vachinje kana motokari yasangana nekubonderana, kuwedzera njodzi yekukuvara. Dambudziko guru nderokuti mavhavha eSeat anozokanganisa kuendesa maairbag, saka zvinokurudzirwa kuti usashandise zvivharo zvezvigaro."

Zvigadzirwa-level zvigadzirwa zvinofanirwa kupa flagship-level chengetedzo
Masayendisiti ekuAmerica akaongorora mazana etsaona dzemotokari dzakakonzera kufa kwevatyairi ndokuona kuti pasina kusunga mabhande ezvigaro, zvinongotora masekonzi 0,7 chete kuti motokari inofamba makiromita 88 paawa irove nekuuraya mutyairi.
Mabhandi ezvigaro ndiwo anoraramisa.Zvava kuzivikanwa nevakawanda kuti kutyaira usina mabhandi ezvigaro kune ngozi uye kusiri pamutemo, asi mabhandi ekumashure haasati awanzofuratirwa.Mumushumo muna 2020, kaputeni wemapurisa emuHangzhou anomhanya-mhanya akataura kuti kubva mukuferefeta nekumhan'ara, chiyero chevapfuuri vakapfeka mabhandi echigaro chaive pasi pe30%.Vazhinji vafambi vezvigaro zvekumashure vakati vaisamboziva kuti vaifanira kupfeka mabhandi ekumashure.
Kuitira kuyeuchidza varimo kuti vasunge mabhandi ezvigaro, panowanzova nechiyeuchidzo chebhandi rechigaro SBR (Safety Belt Reminder) mumutsara wepamberi wemotokari.Isu tinonyatsoziva kukosha kwemabhandi ekumashure uye tinoda kuyeuchidza mhuri yose kuchengetedza ruzivo rwekuchengetedza nguva dzose, saka takaisa SBRs mumutsara wekutanga, wechipiri uye wechitatu."Chero vafambi vari mumutsara wechipiri nechitatu vasingapfeki mabhandi ezvigaro, mutyairi wechigaro chemberi anogona kuyeuchidza vafambi vekumashure kuti vasunge mabhandi avo vasati vasimuka," akadaro Gao Feng, mukuru wezvekuchengetedza mudhipatimendi recockpit. .
Iyo bhandi rekuchengetedza matatu-point ikozvino rinoshandiswa muindasitiri rakagadzirwa naVolvo engineer Niels Bolling muna 1959. Yakavepo kusvika nhasi.Bhandi rakazara rekuchengetedza rinosanganisira retractor, kureba inogadzirisa, yekuvhara bhandi, uye PLP pretensioner.mudziyo.Pakati pavo, iyo retractor uye kukiya inodiwa, nepo kureba inogadzirisa uye PLP pretensioning mudziyo inoda yakawedzerwa mari nebhizinesi.
PLP pretensioner, zita rakazara pyrotechnic lap pretensioner, iro rinogona kududzirwa sezvariri se pyrotechnic belt pretensioner.Basa rayo nderekutungidza nekuputitsa pakaitika kudhumhana, kusimbisa bhandi rechigaro uye kudhonza matako nemakumbo eanogara pachigaro.
Gao Feng akazivisa kuti: "Mune mutyairi mukuru nemutyairi weIdeal L mota dzakatevedzana, takaisa PLP preload zvishandiso, uye zviri mu 'double preload' modhi, kureva, preload muchiuno uye preload pamapfudzi. Kana kubondera kunoitika. , chinhu chekutanga ndechekusimbisa mapendekete kuti ugadzirise torso yepamusoro pachigaro, wozosimbisa chiuno kuti ugadzirise mahudyu nemakumbo pachigaro kuti uvhare zviri nani muviri wemunhu uye chigaro kuburikidza nemasimba maviri ekutanga-kusimbisa mumativi maviri.

Whiplash ndechimwe chekukuvara kwakanyanya kunotsigirwa mutsaona yemotokari kumashure.Nhamba dzinoratidza kuti mu26% yekukonana kwemashure, misoro kana mitsipa yevatyairi nevafambi vachakuvadzwa.Tichifunga nezvekukuvadzwa kwe "whiplash" kumutsipa weanogara kunokonzerwa nekukonana kwekupedzisira, boka rekuchengetedza rekudhumhana rakaitawo zvakawanda se 16 rounds yeFEA (finite element analysis) uye 8 kutenderera kwekuongorora kwepanyama kuongorora nekugadzirisa dambudziko rose duku. ., Kupfuura makumi mashanu kutenderera kwechirongwa kutorwa kwakaitwa, kungoita kuti kukuvadzwa kwemushandisi wega wega panguva yekudhumhana kunogona kuderedzwa.Seat R&D engineer Feng Ge akati, “Panyaya yekudhumhana kwekamwe kamwe kumashure, zvinofungwa kuti hazvisi nyore kuti musoro, chipfuva, dumbu nemakumbo emunhu akuvare zvakaipisisa, asi kunyangwe paine mukana wengozi, hatidi kuisiya."
Kuti udzivise "whiplash" njodzi dzekuchengetedza, Ideal inoomerera pakushandisa nzira mbiri dzemusoro.Nechikonzero ichi, haina kunzwisiswa nevamwe vashandisi uye inoonekwa se "yakasarudzika" zvakakwana.
Zhixing akatsanangura kuti: "Basa guru remusoro wemusoro nderokudzivirira mutsipa.
