Nei Carbon fiber iri kuramba ichizivikanwa muindasitiri yemotokari?

kabhoni faibha (CF) rudzi rutsva rwefiber zvinhu zvine simba rakawanda uye yakakwira modulus yekabhoni yemukati inopfuura 95%. Inoumbwa neflake graphite microcrystals uye mamwe organic fiber akaturikidzana munzira yeaxial yefiber uye inowanikwa necarbonization uye graphitization yemicrocrystalline inki zvinhu. Carbon faibha chinhu chitsva chine yakanakisa mechaniki zvivakwa. Chikamu chayo chisingasviki 1/4 chesimbi. Kusimba kwekusimba kwekabhoni fiber resin inoumbwa kazhinji iri pamusoro pe3500Mpa, inova 7 ~ 9 nguva yesimbi. Asi iyo kabhoni fiber zvinhu chete padivi pefiber axis nhungamiro inoratidza simba rakanyanya, kupikisa kwayo kwakashata uye kuri nyore kukuvadza, saka kugadzira kwezvikamu zvezvimiro kunowanzo shandisa mukana wayo wekutemesa uye unodzivirira kubereka chikamu chikamu.

Nekutsvagisa kwedzidzo kubva kupfupi-fiber kabhoni faibha kusvika-refu-fiber kabhoni faibha, tekinoroji, uye zvigadzirwa zvinoshandisa kabhoni faibha kugadzira zvinhu zvekudziya zvakapinda zvishoma nezvishoma mumauto uye munharaunda. Motokari kabhoni fiber kompositi inogona kushandiswa semotokari dhiraivha shafts, maplate springs, mafuremu, uye brake pads. Parizvino, zvinhu zvesimbi zvinokwana 3/4 yehuremu hwemuviri wemotokari. Kana zvikamu zvese zvesimbi zvemotokari zvakatsiviwa nekabhoni fiber composite zvinhu, huremu hwemuviri wemotokari hwaizoderedzwa ne300kg, kushanda kwemafuta kwaizovandudzwa ne36%, uye kuburitswa kwecarbon dioxide kwaizoderedzwa ne17%.

1. Kushandiswa kwemuviri wemotokari uye chassis, nekuti kabhoni faibha yakasimbisa polymer matrix composite material ine simba rakakwana nekuoma, ndiyo yakareruka pakugadzira zvikamu zvikuru zvezvimiro zvakaita semiviri yemotokari nechasisi. ZVINOTARISIRWA KUTI KUSHANDISWA KWECARBON FIBER COMPOSITE MATERIAL ZVINOGONA KUDUKURERA MAZWI EMOTOMOBILE muviri uye chassis ne 40% ~ 60%, iyo yakaenzana ne1/3 ~ 1/6 yehukuru hwechimiro chesimbi. Iyo yakajairwa mujaho wemota muviri uye chikamu chakagadziridzwa muviri wemotokari zvese ndezveichi chinangwa, uye zvinoonekwa zvinotaridzika zvakanaka uye zvinotonhorera.

2. Kuiswa kwemabhureki pads, carbon fiber inoshandiswawo kumabhureki pads nekuda kwekuchengetedzwa kwayo kwezvakatipoteredza uye kupfeka-resisting maitiro, asi zvigadzirwa zvine carbon fiber composite zvinhu zviri kumusoro, saka rudzi urwu rwebhureki pad rinonyanya kushandiswa mu. mota dzemhando yepamusoro. Carbon fiber brake discs anoshandiswa zvakanyanya mumotokari dzemujaho, senge F1 mota. Inogona kuderedza kumhanya kwemotokari kubva pa300 km/h kusvika 50 km/h iri chinhambwe chemamita makumi mashanu, panguva iyo tembiricha yebhureki disc ichakwira kupfuura 900 ℃, uye brake disc ichatsvuka nekuti. inotora simba rakawanda rekupisa. Iyo kabhoni fiber brake discs inogona kumira tembiricha inosvika 2 500 ° C uye inopa yakanakisa braking kugadzikana.

3, kushandiswa kwevhiri hub, mavhiri hub kugadzira mavhiri muGermany akatanga vhiri nhevedzano, kutora maviri chidimbu dhizaini, mhete yekunze yakagadzirwa nekabhoni fiber zvinhu, uye hubhu yemukati ndeye lightweight alloy, ine simbi isina tsvina, zvichienzaniswa ne. hukuru hwehuremu hwevhiri hunenge 40% pasi. A 20-inch hub, semuenzaniso, inorema 6 kg, nepo hubhu yakajairika inorema 18 kg. Iyo RX-X mhando yepamusoro mota yakakosha vhiri yakagadzirwa naKahm yekuBritain vachishandisa CFRP ine huremu hwe6 kg chete, iyo inogona kumhanya nekumhanya uye kuderedza radial inertia simba revhiri. Yakagadzirwa neDYMAG kuUK, vhiri repasi rose rakareruka kabhoni / magnesium vhiri rine zvikamu zviviri, kabhoni fiber vhiri mesh, uye magnesium brake disc, yakabatana neakakosha titanium-plated hardware.

4, dhiraivha shaft kushandiswa kwesimba remotokari dhiraivha shaft yakanyanya kuoma, kunyanya inofanirwa kutakura torque hombe, ichipa fungidziro yakazara kune kabhoni faibha yakasimbisa composite zvinhu anisotropy, simba rakakura, uye modulus yehunhu hushoma, nekudaro uchishandisa kabhoni fiber. yakasimbiswa composite transmission shaft kutsiva zvigadzirwa zvesimbi, kusangana nezvinodiwa zvekushandisa. Carbon fiber driveshaft haingodzikisi huremu ne60% chete asi zvakare ine nani kuneta kuramba uye kusimba.

Chero bedzi kushandiswa kwekabhoni fiber mumotokari kuzadzisa huremu hwemotokari uye kuzadzisa kuomarara kudiwa kwemotokari, haigone kungozadzisa kudiwa kwepasirese kwekuchengetedza simba uye kuderedzwa kwekuburitsa asi zvakare kusangana nedambudziko rekuchengetedza mafuta. zvinoenderana neVolkswagen.
