I-steering rack - isimiso sokusebenza nokuklama

Kuzo zonke izinhlobo zamagiya okuqondisa, i-rack ne-pinion ithatha indawo ekhethekile, uma nje ivame kakhulu emiklamo yemoto yabagibeli. Ukuba nenani lezinzuzo, ujantshi, futhi yileyo ndlela ovame ukubizwa ngayo kafushane ngesisekelo sokusetshenziswa kwengxenye eyinhloko, uye wathatha indawo yawo wonke amanye amacebo.

Izici zokusebenzisa ama-rails

Ujantshi ngokwawo uyinsimbi eshelelayo enenotshi enamazinyo. Kusukela ohlangothini lwamazinyo, igiya lokushayela licindezelwa kulo. I-shaft yekholomu yokuqondisa ihlukaniswe ku-pinion shaft. I-Helical gearing ivame ukusetshenziswa, njengoba ithule futhi ikwazi ukudlulisa imithwalo ebalulekile.

Uma isiteringi siphenduka, umshayeli, osebenza ngokubambisana ne-power steering, uhambisa irack ngendlela afisa ngayo. Iziphetho zesitimela ngokusebenzisa amalunga ebhola zisebenza ezintini zokuqondisa. Esigabeni sezinduku, ama-couplings anezintambo zokulungiswa kwezinzwane kanye namathiphu ebhola lokuqondisa afakiwe. Ekugcineni, amandla okushayela adluliselwa ngengalo ye-pivot ukuya ku-knuckle, ihabhu, nesondo lokuqondisa ohlangothini ngalunye. Ukucushwa kuklanywe ngendlela yokuthi irabha ingasheleli esiqeshini sokuxhumana, futhi isondo ngalinye lihamba nge-arc yerediyasi oyifunayo.

Ukwakheka kwe-rack kanye ne-pinion steering

Indlela ejwayelekile ihlanganisa:

• indlu lapho zonke izingxenye zitholakala khona, ezifakwe izigxobo zokubopha isihlangu semoto noma uhlaka;
• i-gear rack;
• ama-bearings athafa ohlobo lwemikhono lapho ujantshi uhlezi khona lapho uhamba;
• i-input shaft, evame ukufakwa kuma-roller (inaliti) ama-rolling bearings;
• idivaysi yokulungisa igebe ekuhlanganyeleni kusuka ku-cracker elayishwe entwasahlobo kanye ne-nati yokulungisa;
• bopha amabhuzu enduku.

Kwesinye isikhathi umshini ufakwe i-damper yangaphandle, eklanyelwe ukunciphisa enye yezingqinamba ze-rack kanye ne-pinion mechanism - ukudluliselwa okunamandla ngokweqile kokushaqeka kwesondo lokuqondisa kusuka kumasondo awela ngokungalingani. I-damper iyi-absorber ye-telescopic evundlile efakwe ngokuvundlile, efana naleyo efakwe ekumisweni. Ngakolunye uhlangothi ixhunywe kujantshi, kanti ngakolunye uhlangothi ixhunywe ku-subframe. Yonke imithelela incishwa ama-hydraulic abamba ukushaqeka.

Izindlela ezilula ezisetshenziswa ezimotweni ezilula kakhulu azinawo amandla esiteringi. Kodwa ama-rails amaningi anayo ekubunjweni kwawo. I-hydraulic booster actuator ihlanganiswe nezindlu zokubeka, kuphela izifakelo zokuxhuma imigqa ye-hydraulic ezinhlangothini zesokudla nesobunxele zepiston.

Umsabalalisi ngendlela ye-spool valve kanye nengxenye ye-torsion bar yakhelwe emzimbeni we-shaft yokufaka ye-rack kanye ne-pinion mechanism. Ngokuya ngobukhulu kanye nesiqondiso samandla asetshenziswa umshayeli, ukusonta i-torsion bar, i-spool ivuleka ibheke ekufakweni kwe-hydraulic cylinder kwesokunxele noma kwesokudla, ukudala ukucindezela lapho futhi kusize umshayeli ukuhambisa ujantshi.

Ngezinye izikhathi izakhi ze-amplifier kagesi nazo zakhiwe kumshini wokubeka uma zingatholakali kukholamu yokuqondisa. I-Direct rail drive iyakhethwa. Kulokhu, i-rack ine-motor kagesi ene-gearbox kanye negiya lesibili lokushayela. Isebenza ngokuhambisana ne-main kanye ne-notch yegiya elihlukile kujantshi. Isiqondiso kanye nobukhulu bomzamo kunqunywa iyunithi yokulawula ye-elekthronikhi, ethola isignali kusuka ku-shaft torsion twist sensor futhi ikhiqize amandla amanje enjini kagesi.

Ubuhle nokubi komshini onojantshi

Phakathi kwezinzuzo kukhona:

• ukuqondisa okunembe kakhulu;
• kalula ukuqinisekisa ukucaca kwesondo lokuqondisa, ngisho ifakwe amplifier;
• ukubumbana komhlangano kanye nokuba lula kwesakhiwo sokuklama endaweni yesihlangu semoto;
• isisindo esincane kanye nezindleko eziphansi uma kuqhathaniswa;
• ukuhambisana okuhle nawo womabili ama-hydraulic booster aguga kanye ne-EUR yesimanje;
• ukugcinwa okwanelisayo, amakhithi okulungisa akhiqizwa;
• ukungadingi ukugcotshwa kanye nokugcinwa njalo.

Kukhona futhi ukungalungi:

• ukucaca okuphezulu okuyisisekelo kwesondo lokuqondisa uma kwenzeka lisetshenziswa emigwaqweni emibi, uma ungekho ama-dampers nama-amplifiers anesivinini esikhulu, umshayeli angase alimale;
• umsindo ngendlela yokungqongqoza lapho usebenza ngegebe elikhulayo, lapho ukugqoka kwenzeka ngokungalingani, igebe alikwazi ukulungiswa.

Inhlanganisela yezinzuzo nezingozi ekusebenzeni kwe-rack kanye ne-pinion indlela inquma ububanzi bayo - lezi yizimoto, kuhlanganise nezimoto zezemidlalo, eziqhutshwa ikakhulukazi emigwaqweni emihle ngesivinini esikhulu. Kulokhu, i-rack isebenza ngendlela engcono kakhulu futhi ingaphambi kwazo zonke ezinye izikimu zokuqondisa ngokwezimfanelo zabathengi.

Ukulungiswa komshini kwesinye isikhathi kuyenziwa ukuze kuncishiswe igebe lapho kuvela ukungqongqoza. Ngeshwa, ngenxa yezizathu zokugqoka okungalingani ezichazwe ngenhla, lokhu akunakwenzeka ngaso sonke isikhathi. Ezimweni ezinjalo, umshini uzoshintshwa njengokuhlanganiswa, ngokuvamile kube nefekthri ebuyiselwe. Ukusetshenziswa kwamakhithi okulungisa kususa kuphela ukungqongqoza kuma-bearings kanye nama-bushings asekelayo, kodwa hhayi ukugqokwa kwamagiya. Kodwa ngokuvamile, impilo yesevisi yemishini iphezulu kakhulu, futhi izindleko zezingxenye ezintsha zamukelekile.
