Chii chinonzi rack?
Vanhu vanotaura nezvekumiswa kwemotokari vanowanzoreva "shock absorbers uye struts". Mushure mekunzwa izvi, iwe unogona kunge uchinetseka kuti chii chinonzi strut, chakafanana neinobata chinokatyamadza, uye unofanirwa kunetseka nezve kuchengetedzeka kwemota yako kana rori…
Vanhu vanotaura nezvekumiswa kwemotokari vanowanzoreva "shock absorbers uye struts". Mushure mekunzwa izvi, iwe unogona kunge wakashamisika kuti chii chinonzi strut, chakafanana neinobata chinovhundutsa, uye iwe unofanirwa kunetseka nezve mota yako kana marori.
Chinhu chekutanga kunzwisisa nezve strut ndechekuti ndechimwe chezvikamu zvekumiswa kwemotokari - iyo system yezvikamu zvinobatanidza mavhiri kune yakasara yemotokari. Mabasa matatu makuru ekumisa chero mota:
tsigira motokari
Kutorwa kwezvinovhundutsa kubva kumapundu, makomba uye mamwe mabumps emumugwagwa
Bvumira motokari kuti itendeuke ichipindura kupinza kwemutyairi. (Iyo inotungamira inogona kutorwa sechikamu chekumisikidzwa kana hurongwa hwakasiyana, asi mune chero mamiriro ezvinhu, kumiswa kunofanirwa kubvumira mavhiri kufamba sezvo mota inotendeuka.)
Zvinoitika kuti, kusiyana nezvimwe zvakawanda zvinomisikidzwa, iyo strut inowanzobatanidzwa mune ese matatu emabasa aya.
Chii chiri muraki
Musangano wakakwana we strut musanganiswa wezvikamu zviviri zvikuru: chitubu uye chinokatyamadza. (Dzimwe nguva izwi rekuti "strut" rinongoreva chikamu chekuvhunduka, asi dzimwe nguva izwi rinoshandiswa kureva gungano rose, kusanganisira chitubu.) Chitubu, icho chinenge chinogara chiri chitubu chekoiri (nemamwe mazwi, chitubu chakaita sekoiri), chinotsigira uremu hwemotokari uye chinobata kuvhunduka kukuru. Iyo yekuvhundutsa inopinza, iyo inoiswa pamusoro, pasi, kana pakati chaipo pechitubu checoil, inotsigirawo humwe kana huremu hwese hwemotokari, asi basa rayo rekutanga rakafanana nechero chinobatisa chinovhundutsa, chinova chekudzikisa mavibrations. (Pasinei nezita rayo, chinhu chinokatyamadza hachitore kuvhunduka-ndiro basa rechitubu-asi, chinoita kuti motokari irege kubhowekana nekudzika mushure mekurohwa.) Nekuda kwechimiro chayo chinotakura mutoro, iyo strut inofanira kunge yakasimba zvakanyanya kupfuura yakajairwa kuvhundutsa.
Motokari dzose dzine machira here?
Hadzisi dzese mota nemarori ane mareki; akawanda kuturika magadzirirwo anoshandisa akaparadzana zvitubu uye dampers, pamwe dampers vasingakwanisi kutsigira uremu. Zvakare, dzimwe mota dzinoshandisa mavhiri pavhiri rimwe chete, kazhinji mavhiri epamberi, nepo mamwe maviri ane dhizaini yakasiyana ine zvitubu zvakasiyana uye madhamu. Kana mota iine mavhiri ekumberi chete, kazhinji maMacPherson struts, ayo anoonekwawo sechikamu chechidhiraivho sezvo mavhiri anotenderera achiatenderedza.
Sei dzimwe mota dzichishandisa struts nepo dzimwe dzichishandisa zvitubu zvakaparadzana nemadhamu? Iwo chaiwo akaomesesa, asi kazhinji anouya pasi pekutengesa pakati pekureruka uye yekutanga mutengo (yakanaka: struts) uye kubata uye kuita (zvakanakira: mamwe madhizaini ekumisa pasina struts…kazhinji). Asi pane zvisizvo kune aya mapatani; semuenzaniso, mota zhinji dzemitambo dzinoshandisa iyo inonzi inonzi double wishbone suspension inoshandisa shock absorbers pane struts, asi iyo Porsche 911, iyo ine nharo yemhando yemitambo mota, inoshandisa struts.
Maitiro ekuchengeta racks dzako
Chii chimwe icho muridzi wemotokari anoda kuziva nezve racks? Kwete zvakawanda. Ingave kana mota yako iine ma struts kana kuvhundutsa, unofanirwa kuatarisa nguva nenguva kuti abude kana kumwe kukuvadza. Mumwe musiyano ndewekuti kana dzasakara, zvinodhura kutsiva ma struts, asi hapana chinogona kuitwa nemutyairi nezvazvo. Hazvina mhosva kuti mota yako ine suspension system ipi, iva nechokwadi chekuitarisa nguva nenguva - kuchinja kwemafuta ose kana kugadziridzwa, kana mamaira zviuru zvishanu kana zvakadaro zvakanaka.
