Umbhobho weoyile yegiya yokuqhuba - ngasemva - itshasi ephantsi
Uhlobo lwezixhobo zokuqhuba
Ezisetyenziswa kakhulu zii-rack kunye ne-pinion type, worm crank pin type kunye ne-recirculating ball type.
[1] 1) Izixhobo zokuqhuba ezirhangqiweyo nezirhangqiweyo: Zezona zixhobo zokuqhuba zixhaphakileyo. Ulwakhiwo lwazo olusisiseko yi-pinion kunye ne-rack edibeneyo. Xa i-steering shaft iqhuba i-pinion ukuba ijikeleze, i-rack iya kuhamba ngomgca othe tye. Ngamanye amaxesha, ivili lokuqhuba linokuguqulwa ngokuqhuba ngqo intonga yokubopha ecaleni kwe-rack. Ke ngoko, le yeyona zixhobo zokuqhuba zilula. Inezibonelelo zesakhiwo esilula, ixabiso eliphantsi, ulawulo olunobuthathaka, ubungakanani obuncinci, kwaye inokuqhuba ngqo intonga yokubopha. Isetyenziswa kakhulu kwiimoto.
2) Isixhobo sokuqhuba i-crankpin ye-Worm: Sisigiya sokuqhuba esine-worm njengenxalenye esebenzayo kunye ne-crank pin njengomlandeli. I-worm inentambo ye-trapezoidal, kwaye iphini yomnwe ethambileyo efana nomnwe ixhaswe kwi-crank ene-bearing, kwaye i-crank idityaniswe ne-steering rocker shaft. Xa ijika, i-worm ijikeleziswa livili lokuqhuba, kwaye iphini yomnwe ethambileyo efakwe kwi-spiral groove ye-worm ijikeleza yodwa, ngelixa isenza intshukumo ejikelezayo ejikeleze i-steering rocker shaft, ngaloo ndlela iqhuba i-crank kunye nengalo yokulahla i-steering ukuba ijike, ize idlule kwindlela yokudlulisela i-steering ukuze ijike ivili lokuqhuba. Olu hlobo lwesixhobo sokuqhuba ludla ngokusetyenziswa kwiilori ezinamandla aphezulu okuqhuba.
3) Izixhobo zokuqhuba ibhola ezijikelezayo: inkqubo yokuqhuba ibhola ejikelezayo [2] Isakhiwo esiphambili sinamacandelo amabini: inxalenye yoomatshini kunye nenxalenye ye-hydraulic. Inxalenye yoomatshini yenziwe ngegobolondo, isembozo esisecaleni, isembozo esingaphezulu, isembozo esisezantsi, isikrufu sebhola esijikelezayo, i-rack nut, i-rotary valve spool, i-fan gear shaft. Phakathi kwazo, kukho iipere ezimbini zeepere zokudlulisela: ipere enye yi-screw rod kunye ne-nut, kwaye enye yi-rack, i-tooth fan 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 ziphucula ukusebenza kakuhle kwe-transmission. Inzuzo yale gear yokuqhuba kukuba kulula ukuyisebenzisa, ayinakugugi kakhulu kwaye ihlala ixesha elide. Ingxaki kukuba isakhiwo siyinkimbinkimbi, ixabiso liphezulu, kwaye uvakalelo lokuqhuba alulunganga njengohlobo lwe-rack kunye ne-pinion.
