Menene ainihin abin da ke jan hankalin mota a baya?
Tushen jan hankalin mota na baya, wanda yawanci yake nufin ɓangaren jan hankalin mota a cikin na'urar jan hankalin mota ta baya, shine babban ɓangaren jan hankalin mota, wanda ke da alhakin sha da rage girgiza da tasirin da ke faruwa yayin motsi na abin hawa.
Ainihin na'urar rage danshi ta hydraulic ce, wadda ke ɗauke da abubuwa kamar sandunan piston, pistons, gangaren silinda, man hydraulic (ko iskar gas), da hatimin mai. Lokacin da abin hawa ke tafiya a kan hanyoyi marasa daidaituwa, motsi na ƙafafun sama da ƙasa yana motsa sandunan piston su mayar da martani a cikin gangaren silinda, wanda ke tilasta man hydraulic ya gudana ta cikin ƙananan ramukan matsewa akan pistons, ta haka yana haifar da ƙarfin rage danshi, yana canza kuzarin motsi zuwa makamashin zafi don wargajewa, yana hana maimaita tsalle-tsalle na bazara da kuma inganta santsi da sarrafa tafiyar.
Muhimman bayanai:
Kayan Aiki: Babban sassan tsarin da ke cikin tsakiyar abin sha mai ɗaukar nauyi (kamar sandunan piston da ganga na silinda) galibi ana yin su ne da ƙarfe mai ƙarfi na carbon spring ko ƙarfe mai ƙarfe don tabbatar da dorewa da juriya ga lalacewa.
Ainihin aiki: Ba ya daidai da dukkan tarin abubuwan shaye-shaye ba, amma yana nufin musamman ɓangaren "cylindrical" wanda ke samar da damping. Duk tarin abubuwan shaye-shaye na baya ya haɗa da abubuwan da suka haɗa da maɓuɓɓugan coil, kujerun bazara, maƙallan ƙarfe, gaskets, da murfi.
Shawarar Gyara: Ko zai yiwu a maye gurbin tsakiyar abin sha mai girgiza shi kaɗai ya dogara da tsarin dakatarwar motar. A cikin dakatarwar baya mai haɗin gwiwa da yawa, tunda ƙarfin yana da sauƙi (galibi a cikin alkiblar sama da ƙasa), maye gurbin tsakiyar shi kaɗai abu ne mai yiwuwa kuma hanyar kulawa ce gama gari. Duk da haka, a cikin dakatarwar gaba ta McPherson, tunda silinda mai sha mai girgiza yana ɗauke da ƙarfin gefe mai rikitarwa, idan aka maye gurbin tsakiyar shi kaɗai ba tare da daidaita kusurwar bazara ba, yana da yuwuwar haifar da lalacewar hatimin mai da ɓuɓɓuga, don haka gabaɗaya ana ba da shawarar a maye gurbin dukkan taron.
Saboda haka, idan ana maganar "ƙarfin girgizar baya", yana nufin jikin silinda na hydraulic a cikin na'urar ɗaukar girgizar da ke da alhakin aikin damping, kuma muhimmin sashi ne wanda ke tabbatar da jin daɗi da kwanciyar hankali na abin hawa.
Tushen mai ɗaukar girgizar baya shine babban abin da ke motsa motar a cikin na'urar ɗaukar girgizar. Ba ya haɗuwa kai tsaye da jiki ko ƙafafun, amma yana ɗaukar babban aikin canza tasirin hanya zuwa juriyar hydraulic mai sarrafawa. Ita ce ɓangaren "zuciya" wanda ke ƙayyade aikin dakatarwar baya na motar.
Manyan ayyukansa sune kamar haka:
Sha da canza kuzarin tasiri: Lokacin da abin hawa ya ratsa hanyoyi marasa daidaituwa kamar ramuka da ramuka, ƙarfin tasiri akan ƙafafun yana tafiya zuwa tsarin dakatarwa. Tushen mai shaye-shaye na baya, ta hanyar tsarin bawul ɗin piston daidai da tsarin da'irar mai a ciki, yana canza wannan kuzarin tasiri zuwa juriyar kwararar mai na hydraulic, yana rage jin girgiza na jikin abin hawa sosai.
Sarrafa farfadowar bazara da daidaita yanayin motar: Maɓuɓɓugar ruwa a cikin tsarin dakatarwa tana da alhakin tasirin buffering, amma da kanta za ta fuskanci maimaita tsalle. Tushen mai ɗaukar girgiza na baya yana ba da daidaiton damping (juriya yayin matsin lamba ƙasa) da kuma damping na rebound (juriya yayin rebound), yana danne yawan dawowar bazara da kuma hana jikin motar ci gaba da tsalle, yana tabbatar da cewa tayoyin koyaushe suna da kyakkyawar hulɗa da ƙasa.
Inganta kwanciyar hankali da kwanciyar hankali a kan hawa: Ta hanyar daidaita ƙarfin damping daidai, zuciyar mai shaƙar girgiza ta baya na iya cimma daidaito tsakanin "ta'aziyya" da "goyon baya". Idan damping ɗin ya yi laushi sosai, zai haifar da ƙarin girgiza jiki da birgima a gefe; idan damping ɗin ya yi tauri sosai, zai watsa girgiza da yawa, yana shafar jin daɗi. Tsarin da aka gyara a masana'anta zai iya cimma halayyar chassis "mai ƙarfi amma ba mai sauri ba", musamman a lokacin kusurwa, birki na gaggawa, ko canje-canje a layin sauri, yana inganta riƙon ƙafafun baya da kwanciyar hankali gaba ɗaya na abin hawa.
Tabbatar da amincin tuƙi: Tsarin mota mai kyau shine tushen tuƙi mai aminci. Tushen jan hankalin mota na baya yana rage girgizar jikin mota, yana tabbatar da kwanciyar hankali yayin birki da kuma inganta ikon sarrafa abin hawa a cikin yanayi mai rikitarwa na hanya, yana inganta amincin tuƙi a kaikaice.
A taƙaice, ƙwanƙolin mai ɗaukar girgiza na baya shine ƙwanƙolin da ke samun "sha da sauri da kwanciyar hankali". Yana bawa abin hawa damar jure tasirin hanya ba tare da "girgiza" ko "girgiza" ba, yana daidaita jin daɗi da sarrafawa.
Idan kana son ƙarin bayani, ci gaba da karanta sauran labaran da ke wannan shafin!
Don Allah a kira mu idan kuna buƙatar irin waɗannan kayayyaki.
