Umbhobho weoyile wokuqhuba - ngasemva - i-chassis ephantsi
Uhlobo lwesixhobo sokuqhuba
Ngokuqhelekileyo kusetyenziswa uhlobo lwe-rack kunye ne-pinion, uhlobo lwe-worm crank pin kunye nohlobo lwebhola ejikelezayo.
[1]1 Isakhiwo sayo esisisiseko sisibini se-intermeshing pinion kunye ne-rack. Xa i-steering shaft iqhuba i-pinion ukujikeleza, i-rack iya kuhamba ngendlela echanekileyo. Ngamanye amaxesha, ivili lokuqhuba linokujikwa ngokuqhuba ngokuthe ngqo intonga yokubopha nge-rack. Ke ngoko, le yeyona nto ilula yokulawula. Ineenzuzo zesakhiwo esilula, indleko ephantsi, i-steering steering, ubungakanani obuncinci, kwaye inokuqhuba ngokuthe ngqo intonga yokubopha. Isetyenziswa kakhulu kwiimoto.
2) Isixhobo sokulawula i-worm crankpin: Sisixhobo sokuqhuba esinombungu njengendawo esebenzayo kunye nephini lokukranxa njengomlandeli. I-worm inentambo ye-trapezoidal, kwaye iphini lomnwe elifakwe kwi-tapered lixhaswa kwi-crank kunye ne-bearing, kwaye i-crank idibaniswe ne-rocker shaft. Xa ujika, intshulube ijikeleziswa livili lokuqhuba, kwaye isikhonkwane somnwe esithe jize esifakwe kwi-spiral groove ye-worm ijikeleza yodwa, ngelixa isenza intshukumo ejikelezayo ijikeleze i-rocker shaft, ngaloo ndlela iqhuba i-crank kunye nengalo yokuwisa. ukujinga, kwaye emva koko ngendlela yosasazo lokuqhuba ukwenza ivili lokuqhuba lijike. Olu hlobo lwezixhobo zokuqhuba ludla ngokusetyenziswa kwiilori ezinamandla okuqhuba.
I-3) Ukujikeleza kwakhona i-ball steering gear: i-recirculating ibhola ye-steering system yokulawula amandla [2] Isakhiwo esiphambili sineenxalenye ezimbini: inxalenye yomatshini kunye nenxalenye ye-hydraulic. Inxalenye yomatshini yenziwe ngeqokobhe, isigqubuthelo esisecaleni, isigqubuthelo esingaphezulu, isigqubuthelo esisezantsi, isikrufu sebhola ejikelezayo, i-rack nut, i-rotary valve spool, ishaft yegiya yefeni. Phakathi kwazo, kukho izibini ezimbini zokuhambisa: enye ibini yintonga ye-screw kunye ne-nut, kwaye enye ibini i-rack, i-fan yamazinyo okanye i-fan shaft. Phakathi kwe-screw rod kunye ne-rack nut, kukho iibhola zentsimbi ezijikelezayo ezijikelezayo, ezitshintsha i-sliding friction ibe yi-rolling friction, ngaloo ndlela iphucula ukusebenza kakuhle kokudluliselwa. Inzuzo yesi sixhobo sokuqhuba kukuba kulula ukusebenza, ayinayo into encinci kunye nobomi obude. Ukungalungi kukuba ulwakhiwo luyinkimbinkimbi, ixabiso liphezulu, kwaye ukuvakalelwa kokulawula akulunganga njenge-rack kunye ne-pinion hlobo.
