Iyini irack?

Abantu abakhuluma ngokumiswa kwemoto bavame ukusho "ama-shock absorbers nama-struts". Ngemva kokuzwa lokhu, ungase uzibuze ukuthi iyini i-strut, ingabe iyafana ne-shock absorber, futhi ingabe udinga ukukhathazeka ngokuphepha kwemoto yakho noma iloli...

Abantu abakhuluma ngokumiswa kwemoto bavame ukusho "ama-shock absorbers nama-struts". Ngemva kokuzwa lokhu, ungase uzibuze ukuthi yini i-strut, ingabe iyafana ne-shock absorber, futhi udinga ukukhathazeka ngemoto yakho noma ama-struts weloli.

Into yokuqala okumele uyiqonde nge-strut ukuthi ingenye yezingxenye ze-suspension yemoto - uhlelo lwezingxenye ezixhumanisa amasondo nayo yonke imoto. Imisebenzi emithathu eyinhloko yokumiswa kwanoma iyiphi imoto:

• ukusekela imoto

• Ukumuncwa ukushaqeka ngenxa yamabhampa, imigodi kanye namanye amabhampa omgwaqo

• Vumela imoto ukuthi iphendule ekufakweni komshayeli. (Isistimu yokuqondisa ingabhekwa njengengxenye yokumiswa noma isistimu ehlukile, kodwa kunoma yikuphi, ukumiswa kufanele kuvumele amasondo ukuhamba njengoba imoto ijika.)

Kuvela ukuthi, ngokungafani nezinye izingxenye eziningi zokumiswa, i-strut ivamise ukubandakanyeka kuyo yomithathu le misebenzi.

Yini esendaweni yokubeka

Umhlangano ophelele we-strut uyinhlanganisela yezingxenye ezimbili eziyinhloko: isiphethu kanye ne-shock absorber. (Ngezinye izikhathi igama elithi "strut" libhekisela engxenyeni kuphela ye-shock absorber, kodwa ngezinye izikhathi leli gama lisetshenziselwa ukubhekisela kuyo yonke inhlangano, kuhlanganise nentwasahlobo.) Intwasahlobo, cishe njalo iyisiphethu sekhoyili (ngamanye amazwi, isiphethu esimise okwekhoyili), sisekela isisindo semoto futhi sibamba ukushaqeka okukhulu. I-shock absorber, efakwe phezulu, phansi, noma maphakathi ne-coil spring, nayo isekela esinye noma sonke isisindo semoto, kodwa umsebenzi wayo oyinhloko uyafana nanoma yisiphi i-shock absorber, esiwukudambisa ukudlidliza. (Naphezu kwegama laso, i-shock absorber ayibambeli ngokuqondile ukushaqeka-lowo ngumsebenzi wesiphethu - kunalokho, igcina imoto ingagxuma phezulu naphansi ngemva kokushaywa.) Ngenxa yesakhiwo sayo esithwala umthwalo, i-strut kufanele ibe namandla kakhulu kune-absorber evamile yokushaqeka.

Ingabe zonke izimoto zinama-rack?

Akuzona zonke izimoto namaloli anama-rack; imiklamo eminingi yokumiswa isebenzisa iziphethu ezihlukene kanye nama-dampers, nama-dampers angakwazi ukusekela isisindo. Futhi, ezinye izimoto zisebenzisa ama-struts esondweni elilodwa kuphela, ngokuvamile amasondo angaphambili, kuyilapho elinye linomklamo ohlukile oneziphethu nama-dampers ahlukene. Uma imoto inamasondo angaphambili kuphela, imvamisa ama-MacPherson struts, nawo athathwa njengengxenye yesiteringi njengoba amasondo ewazungeza.

Kungani ezinye izimoto zisebenzisa ama-struts kuyilapho ezinye zisebenzisa iziphethu ezihlukene nama-dampers? Imininingwane iyinkimbinkimbi, kodwa ingxenye enkulu yehlela ekuhwebeni phakathi kokulula kanye nezindleko zokuqala (inzuzo: ama-struts) nokuphatha nokusebenza (inzuzo: eminye imiklamo yokumiswa ngaphandle kwama-struts…ngokuvamile). Kodwa kukhona okuhlukile kulawa maphethini; isibonelo, izimoto eziningi zezemidlalo zisebenzisa lokho okubizwa ngokuthi yi-double wishbone suspension esebenzisa ama-shock absorbers esikhundleni se-struts, kodwa i-Porsche 911, okungangabazeki imoto yezemidlalo evamile, isebenzisa ama-struts.

Ungawagcina kanjani ama-racks akho

Yini enye umnikazi wemoto okudingeka akwazi ngayo ngamarack? Akukho kuningi. Kungakhathaliseki ukuthi imoto yakho inama-struts noma ama-absorber ashaqisayo, udinga ukuwahlola ngezikhathi ezithile ukuvuza noma omunye umonakalo. Omunye umehluko wukuthi uma sezigugile kuyabiza ukuvala ama-struts kodwa akukho angakwenza umshayeli. Kungakhathaliseki ukuthi iyiphi isistimu yokumiswa imoto yakho, qiniseka ukuthi uyayihlola njalo - konke ukuguqulwa kukawoyela noma ukulungiswa, noma njalo ngamamayela angu-5,000 noma ngaphezulu kulungile.
