Buri mukanishi yazikoresheje, ariko abenshi ntibazi ubwoko butandukanye bw'imashini zo kumesa zihari, ibikoresho zikozemo, n'uburyo bwo kuzikoresha neza. Mu myaka yashize, twakiriye ibibazo byinshi bijyanye n'imashini zo kumesa, bityo ingingo y'ikoranabuhanga yo gusangira amakuru kuri izi mashini za mudasobwa irakererewe.

Duherutse kuvuga ku buhanga bwo gukora ibipfunyika bifite imikorere myiza dukoresheje Automotive Racing Products, Inc. (ARP), bitwikira neza ingingo z'ingenzi. Ubu ni cyo gihe cyo kubahiriza igice cy'ibipfunyika gikunze gufatwa nk'ikintu cyoroshye, imashini yoza imyenda iciriritse.

Mu ngingo zikurikira, tuzavuga ku byo imesa amazi ari byo, ubwoko butandukanye bw'imesa amazi, icyo zikora, uko zikorwa, aho zikoreshwa n'igihe cyo kuzikoresha - kandi yego, tuzanaganira niba imesa amazi ari mu cyerekezo cyangwa atari cyo.

Muri rusange, imashini yo kumesa ni isahani isa na disiki, isa n'iy'isukari ifite umwobo hagati. Nubwo imiterere yayo ishobora kumvikana nk'iy'ubusanzwe, imashini zo kumesa zitanga akazi katoroshye. Zikunze gukoreshwa mu gukwirakwiza umutwaro w'icyuma gifunga imigozi, nk'imashini ifunga cyangwa umupfundikizo.

Zishobora kandi gukoreshwa nk'ibice bigabanya ubushyuhe - cyangwa rimwe na rimwe - zishobora kuba agakoresho ko kwambara, igikoresho gifunga, cyangwa ndetse zigakoreshwa mu kugabanya ubushyuhe - nk'icyuma gikaraba. Igishushanyo mbonera cy'ibanze cy'icyuma gikaraba gifite umurambararo w'inyuma uruta kabiri umurambararo w'imbere w'icyuma gikaraba.

Ubusanzwe ikorwa mu byuma, imashini zimesa zishobora no gukorwa muri pulasitiki cyangwa rubber — bitewe n’uburyo zikoreshwa. Mu mashini, ingingo zifite imigozi myiza zisaba imashini zimesa ibyuma bikomeye kugira ngo hirindwe ko impande z’ingingo zihagarara. Ibi byitwa Brinelling. Utu duce duto dushobora gutuma imashini itakaza umutwaro, ivungagurika, cyangwa ihindagurika ryinshi. Uko ikibazo gikomeza, izi ngendo zishobora kwihuta mu zindi ngendo zikunze guhindurwa nk’ivunga cyangwa ishavu.

Utwuma two kumesa dufasha kandi gukumira ingese ya galvanic, ikibazo kibaho iyo ibyuma bimwe na bimwe bihuye. Icyuma kimwe gikora nk'anode, ikindi nk'umuyoboro wa cathode. Kugira ngo bigabanye cyangwa bikumire iki gikorwa kuva mu ntangiriro, hakoreshwa imashini yo kumesa hagati y'umugozi cyangwa nut n'icyuma gifatanye.

Uretse gukwirakwiza neza igitutu ku gice gifashwe neza no kugabanya amahirwe yo kwangiza igice, imashini zoza zitanga ubuso bworoshye ku giti cyangwa bolt. Ibi bituma igice gifatanye kidakunze kurekura ugereranyije n'igice gifatanye kitaringaniye.

Hari utumashini two koza two mu mazi twihariye twagenewe gutanga igipfundikizo, aho amashanyarazi ahagarara, gushyira igipfundikizo mu buryo buhamye, gufata igipfundikizo mu buryo bufunze, gukingira, cyangwa gutanga umuvuduko w’umugongo ku ngingo. Tuzaganira kuri izi mashini zidasanzwe mu nyandiko iri hepfo.

Twabonye kandi uburyo bubiri bwo gukoresha nabi utumashini two kumesa nk'igice cy'agace gafatanye. Hari ingero nyinshi aho abakanishi b'ibiti by'igicucu bakoresheje utubuto cyangwa imbuto zifite umurambararo muto cyane ku gice zihuriraho. Muri izi ngero, utumashini two kumesa dufite umurambararo w'imbere ujyanye n'utubuto, nyamara ntitwemerera umutwe w'utubuto cyangwa imbuto kunyura mu mwobo w'igice gifatanye. Ibi ni ukwibaza ibibazo kandi ntibigomba kugeragezwa ahantu hose ku modoka y'amasiganwa.

Akenshi, abakanishi bakoresha bolt ndende cyane, ariko idafite imigozi ihagije, ituma ingingo idakomera. Gushyiramo utumashini duto two kumesa ku gice cy'inyuma kugeza igihe nut ishobora gukomera nabyo bigomba kwirindwa. Hitamo uburebure bukwiye bwa bolt. Gukoresha utumashini two kumesa nabi bishobora kwangiza cyangwa gukomeretsa.

Muri rusange, hari ubwoko butandukanye bw'imashini zo kumesa zikorwa ku isi muri iki gihe. Zimwe zikorerwa ku giti mu buryo bwihariye, izindi zikoreshwa mu bijyanye n'amazi. Ku bijyanye n'ibikenewe mu modoka, inzobere mu bushakashatsi no guteza imbere imodoka muri ARP, Jay Coombes, atubwira ko hari ubwoko butanu gusa bukoreshwa mu kubungabunga imodoka. Hari imashini yo kumesa isanzwe (cyangwa imashini yo kumesa isanzwe), imashini yo kumesa isanzwe, imashini yo kumesa ivanze (cyangwa imashini yo kumesa ifunguye), imashini yo kumesa ikoresheje inyenyeri, n'imashini yo kumesa ikoreshwa mu imashini.

Igishimishije ni uko nta mashini yo koza igabanyijemo ibice mu bikoresho bikomeye bya ARP. Coombes yasobanuye ati: “Bigira akamaro cyane cyane ku bikoresho bito bifite umurambararo mu gihe gito cyane.” ARP ikunze kwibanda ku bikoresho byo gusiganwa bigezweho kandi bikora neza mu gihe cy’umutwaro mwinshi. Hari ubwoko bw’ubwo bwoko bw’ibikoresho byo koza bukora imirimo yihariye, nk’imashini isanzwe ifite utudomo munsi.

Akamashini koza gafite ibara rirambuye ni ko gakoreshwa cyane hagati y’umutwe w’icyuma gifata (cyangwa nut) n’ikintu gifatanye. Intego yacyo y’ibanze ni ugukwirakwiza umutwaro w’icyuma gifata gikonje kugira ngo hirindwe kwangirika kw’ubuso bufatanye. Coombes agira ati: “Ibi ni ingenzi cyane ku bice bya aluminiyumu.”

Ikigo cy’Igihugu cy’Ubuziranenge cya Amerika (ANSI) cyatanze amabwiriza ngenderwaho yo gukoresha muri rusange, ayo mashini zisanzwe zisaba ubwoko bubiri. Ubwoko bwa A busobanurwa nk'imashini zisanzwe zifite ubushobozi bwo kwihanganira ibintu byinshi aho ubuziranenge butari ngombwa. Ubwoko bwa B ni imashini isanzwe ifite ubushobozi bwo kwihanganira ibintu bikomeye aho uburebure bw'inyuma bushyirwa mu byiciro nk'ubuto, busanzwe, cyangwa bunini bitewe n'ingano ya bolt (umurambararo w'imbere).

Nkuko twabivuze mbere, utumashini two kumesa imyenda turagoye kuruta ibisobanuro byoroshye byatanzwe n'ikigo kimwe. Mu by'ukuri, hari byinshi. Ishyirahamwe ry'Abahanga mu by'Imodoka (SAE) rishyira utumashini two kumesa imyenda mu byiciro bitandukanye mu bunini bw'ibikoresho, dufite umurambararo muto imbere n'inyuma ugereranije n'uko umuryango w'Ubuziranenge bwa Leta Zunze Ubumwe za Amerika (USS) wasobanuye utumashini two kumesa imyenda duto.

Amabwiriza ya USS ni amahame agenga imesa ikoresheje santimetero. Uyu muryango ugaragaza umurambararo w'imesa imbere n'inyuma kugira ngo ijyane n'imigozi ikomeye cyangwa minini. Amasaha ya USS akunze gukoreshwa mu modoka. Hamwe n'imiryango itatu igaragaza amahame atatu atandukanye ku imesa isanzwe, biragaragara ko imesa igoye cyane kuruta uko isura yayo yoroshye yatuma umuntu abyemera.

Nk’uko Coombes wo muri ARP abivuga, “Ingano n’ubwiza bw’icyuma gikaraba ubwacyo bikwiye kwitabwaho cyane. Gikwiye kugira ubugari n’ingano bihagije kugira ngo gikwirakwize neza umutwaro.” Coombes yongeraho ati: “Ni ngombwa kandi ko icyuma gikaraba kiba giteye ku butaka kandi gitunganye neza kugira ngo gikoreshwe mu buryo bw’ingenzi hamwe n’umutwaro mwinshi. Ikindi kintu cyose gishobora gutera ubwinshi bw’ibikoresho mbere yo gukaraba.”

Izi ni imashini zo koza zifite umurambararo munini cyane wo hanze ugereranije n'umwobo wayo wo hagati. Zagenewe kandi gukwirakwiza imbaraga zo gufunga, ariko kubera ingano nini, umutwaro unyura ahantu hanini. Mu myaka myinshi, izi mashini zo koza zakoreshejwe mu gushyiramo imashini zo koza ku modoka, ari na yo mpamvu zizwi. Imashini zo koza zishobora kugira umurambararo munini wo hanze, ariko ubusanzwe zikozwe mu bikoresho bipima buhoro.

Utwuma two koza twometse hamwe dufite ubushobozi bwo koroha kandi dukoreshwa mu gukumira gucika intege bitewe no guhindagura. Ifoto yavuye kuri www.amazon.com.

Udukoresho two gukaraba twiswe split washers, kandi twitwa spring washers cyangwa lock washers, dufite ubushobozi bwo koroha. Udukoresho dukoreshwa mu gukumira gucika intege bitewe no kunyeganyega. Igitekerezo kiri inyuma y'udukoresho two gukaraba twiswe split washers ni gito: Dukora nk'isoko yo gushyira igitutu ku kintu gifatanye n'umutwe w'icyuma cyangwa nut.

ARP ntabwo ikora izi meseji kuko inyinshi mu byuma bikora uruhare runini muri moteri, drivetrain, chassis, na suspension ziba zifashe ku rugero runaka, zigakoresha imbaraga zikwiye zo kuzifunga. Nta mahirwe menshi cyangwa ntayo afite yo kohereza imashini idakoresheje igikoresho.

Injeniyeri nyinshi zemeza ko imashini yo kumesa ikoresha impera - iyo ishyizwe ku rugero rwo hejuru - izaramba ku rugero runaka. Iyo ibyo bibaye, imashini yo kumesa igabanyijemo ibice izatakaza imbaraga zayo ndetse ishobora no kubangamira uburyo bwo gushyiramo neza igice gifatanye.

Utwuma two koza inyenyeri dufite utubuto tunyura imbere cyangwa inyuma kugira ngo tujye ku gice cy'ubutaka kugira ngo wirinde ko imashini ifunga irekura. Ifoto yavuye kuri www.amazon.com.

Utwuma two gukaraba tw’inyenyeri dukora hafi ya two gukaraba tw’imashini. Tugamije gukumira ko imashini yo gukaraba idacika. Utwo dusumezo dufite utudomo duto duto (imbere cyangwa inyuma) kugira ngo tujye kuruma hejuru y’igice. Mu buryo bw’imiterere, tugomba "gucukura" ku mutwe w’agapira/umuti n’agapira kugira ngo tutukure. Utwuma two gukaraba tw’inyenyeri dukoreshwa n’utubuto duto n’udupira dufitanye isano n’ibikoresho by’amashanyarazi.

Kubuza ko ibintu bizunguruka, bityo bigatuma habaho imikorere myiza mbere yo gushyiramo ibintu, byatumye ARP ikora imashini zidasanzwe zoza zishyirwa munsi y’umuyoboro. Igitekerezo ni uko zifata ikintu gifatanye kandi zigatanga urubuga ruhamye.

Indi mashini yihariye yo kumesa ikorwa na ARP ni imashini yo kumesa ikoreshwa mu buryo bwo kuyinjiza. Yagenewe kurinda hejuru y'imyobo kugira ngo hirindwe ko ipfuka cyangwa ko hejuru y'imyobo igwa. Ikoreshwa risanzwe ririmo imitwe ya silinda, ibice bya chassis, n'ahandi hantu hakenera imashini yo kumesa cyane.

Ni ngombwa kumenya ko amavuta yo kwisiga agira uruhare runini mu gushyira amavuta neza mbere yo kuyashyira. Uretse gushyira amavuta yo kwisiga ku migozi y'icyuma gifunga, ni byiza gushyiramo make ku gice cyo hasi cy'umutwe w'icyuma gifunga (cyangwa nut) cyangwa hejuru y'icyuma gisukura. Ntuzigere ushyira amavuta ku gice cyo hasi cy'icyuma gisukura (keretse niba amabwiriza yo gushyiraho abivuga ukundi) kuko udashaka ko kizunguruka.

Kwita ku ikoreshwa ry’imiyoboro yo kumesa no kuyisiga neza ni ikintu gikwiye kwitabwaho n’amakipe yose yo gusiganwa.
