Steering rack - musimboti wekushanda uye dhizaini

Pakati pemhando dzese dzemagiya mabhokisi, rack uye pinion inotora nzvimbo yakakosha, kana chete nekuti inowanzoitika mumagadzirirwo emotokari yevafambi. Kuva nezvakanakira zvinoverengeka, njanji, uye ndiwo madanirwo ainowanzoitwa kwenguva pfupi pahwaro hwekushandiswa kwechikamu chikuru, yakatotsiva zvimwe zvirongwa zvese.

Zvimiro zvekushandisa njanji

Rail pachayo isimbi inotsvedza ine notch ine mazino. Kubva padivi pemeno, giya rekutyaira rinodzvanywa pariri. Iyo inotungamira mbiru shaft yakakamurwa kune pinion shaft. Helical gearing inowanzo shandiswa, sezvo yakanyarara uye inokwanisa kuendesa mitoro yakakosha.

Kana chidhiraivho chichitenderedzwa, mutyairi, achishanda pamwe chete nechidhiraivho chesimba, anofambisa rack munzira yaunoda. Migumo yenjanji kuburikidza nemajoini ebhora inoshanda pamatanda ekutungamirira. Muchikamu chematanda, tambo dzakasungirirwa dzekugadzirisa zvigunwe uye mazano ekutungamirira bhora akaiswa. Pakupedzisira, simba rekufambisa rinopfuudzwa kuburikidza nepivot ruoko kune knuckle, hub, uye vhiri rinotungamirira kune rumwe rutivi. Iyo gadziriso inogadzirwa nenzira yekuti rabha haitsvedzeri muchikamu chekusangana, uye vhiri rega rega rinofamba nearc yeradius yaunoda.

Kuumbwa kwe rack uye pinion steering

Iyo yakajairika michina inosanganisira:

• imba iyo nzvimbo dzese dziripo, dzakashongedzerwa nemakumbo ekusungirira kune mota nhoo kana furemu;
• gear rack;
• sleeve-type plain bearings iyo njanji inozorora kana ichifamba;
• kupinza shaft, kazhinji kuiswa mu roller (tsono) rolling bearings;
• chigadziro chekugadzirisa gaka mukubatana kubva kune chitubu-chakatakura cracker uye nut inogadzirisa;
• sunga tsvimbo bhutsu.

Dzimwe nguva michina yacho inoshongedzerwa neyekunze damper, yakagadzirirwa kudzikisa chimwe chezvipingamupinyi zveiyo rack uye pinion mechanism - kutapurirana kwakasimba zvakanyanya kwekuvhundutsa kune chidhiraivho kubva kumavhiri anowira pamavhiri asina kuenzana. Iyo damper ndeye yakachinjika yakamisikidzwa telescopic shock absorber, yakafanana neiyo yakaiswa mukumiswa. Kune imwe mugumo yakabatanidzwa kune njanji, uye kune imwe mugumo kune subframe. Zvese zvinokonzeresa zvakanyoroveswa neiyo shock absorber hydraulics.

Nzira dzakareruka dzinoshandiswa pamotokari dzakareruka hadzina chidhiraivho chemagetsi. Asi njanji zhinji vanayo mukuumbwa kwavo. Iyo hydraulic booster actuator inosanganiswa mune rack imba, chete zvigadziriso zvekubatanidza hydraulic mitsara kurudyi nekuruboshwe mativi episton anobuda.

Muparadzi ari muchimiro chevhavhavha ye spool uye chikamu che torsion bar inovakwa mukati meimba yekupinza shaft ye rack uye pinion mechanism. Zvichienderana nehukuru uye kutungamira kwekuedza kunoshandiswa nemutyairi, kumonyorora bhara rekutambisa, spool inovhura yakananga kuruboshwe kana kurudyi hydraulic cylinder fittings, ichigadzira kumanikidza ipapo uye kubatsira mutyairi kutamisa njanji.

Dzimwe nguva zvinhu zvemagetsi amplifier zvakare zvakavakwa mukati meiyo rack meshini kana isiri panzvimbo yekutungamirira. Direct rail drive inodiwa. Muchiitiko ichi, rack ine mota yemagetsi ine gearbox uye yechipiri dhiraivha giya. Inoshanda pamwe chete neiyo huru pamwe neyakasiyana giya notch pachitima. Iyo inotungamira uye ukuru hwesimba inotarwa neiyo yemagetsi control unit, iyo inogamuchira chiratidzo kubva kune inopinza shaft torsion twist sensor uye inogadzira simba razvino kune yemagetsi mota.

Zvakanakira uye kuipa kwechigadzirwa chine njanji

Pakati pezvakanakira ndezvi:

• high precision steering;
• kusununguka kwekuona pachena kwevhiri rekufambisa, kunyange rakagadzirirwa neamplifier;
• iyo compactness yegungano uye kureruka kweiyo dhizaini dhizaini munzvimbo yemota shield;
• uremu huremu uye mutengo wakaderera;
• kuwirirana kwakanaka nezvose zviri zviviri kuchembera hydraulic boosters uye EUR yemazuva ano;
• kuchengetedza kunogutsa, makiti ekugadzirisa anogadzirwa;
• kusada kukwirisa uye kugara uchigadzirisa.

Panewo zvazvakaipira:

• kunyanya kujeka kwechidhiraivho kana kushandiswa mumigwagwa yakaipa, pasina madhamu uye maamplifiers akakwira-speed, mutyairi anogona kukuvara;
• ruzha muchimiro chekugogodza kana uchishanda negomba rakawedzera, kana kupfeka kuchiitika zvisina kuenzana, gomba harigone kugadziriswa.

Iko kusanganiswa kwezvakanakira uye zvakaipira mukushanda kweiyo rack uye pinion michina inosarudza chiyero chayo - idzi imotokari, kusanganisira mota dzemitambo, dzinoshandiswa zvakanyanya mumigwagwa yakanaka nekumhanya kwakanyanya. Muchiitiko ichi, rack inoita nenzira yakanakisisa uye iri mberi kwezvimwe zvirongwa zvekutungamirira maererano neunhu hwevatengi.

Kugadziriswa kweiyo mechanic dzimwe nguva kunoitwa kuitira kuderedza gap kana kugogodza kuchioneka. Zvinosuruvarisa, nokuda kwezvikonzero zvekupfeka zvisina kufanana zvinotsanangurwa pamusoro apa, izvi hazviiti nguva dzose. Mumamiriro ezvinhu akadaro, michina ichatsiviwa segungano, kazhinji nefekitari yakadzorerwa. Iko kushandiswa kwekugadzirisa kits kunobvisa chete kugogodza mumabhengi uye kutsigira bushings, asi kwete kupfeka kwegiya pair. Asi kazhinji, hupenyu hwebasa hwemashini hwakanyanya, uye mutengo wezvikamu zvitsva unogamuchirwa.
