01 Inkqubo yoLawulo lwaMandla oMbane oHaydraulic

Njengoko kuboniswe kwi-Figure 1, i-Electric Hydraulic Power Steering (EHPS) inkqubo yenziwe nge-hydraulic power steering (HPS) kunye nemoto yombane, exhasa i-interface ye-HPS yokuqala. Inkqubo ye-EHPS ifanelekile kwiilori ezilula, eziphakathi, kunye nezinzima, kunye nabaqeqeshi abaphakathi kunye nabakhulu. Ngophuhliso olukhawulezayo lwezithuthi zorhwebo zamandla amatsha (ezifana neebhasi, ukuhanjiswa, kunye nogutyulo), umthombo wamandla wempompo yokulawula amandla endalo okwenziwa ngoxinzelelo lwehydraulic utshintshile ukusuka kwi-injini ukuya kwi-motor, kunye nenkqubo yebhetri ephezulu yombane kwisithuthi yenza kube lula ukusebenzisa impompo yombane enamandla amakhulu. Inkqubo ye-EHPS ibhekiselele kwinkqubo yokulawula amandla okwenziwa ngoxinzelelo lwe-hydraulic esebenzisa impompo yombane yamandla aphezulu.

Njengoko inkxalabo yesizwe yokhuseleko kunye nomgangatho wezithuthi zamandla amatsha zanda, umgangatho onyanzelekileyo wesizwe "I-GB38032-2020 Iimfuno zoKhuseleko lweBhasi yoMbane" yakhutshwa ngoMeyi 12, 2020. Icandelo 4.5.2 longeze iimfuno zolawulo lwenkqubo yokuncedisa amandla ngexesha lokuqhuba. Okokuthi, ngexesha lokuqhuba isithuthi, xa isithuthi sonke sifumana imeko engaqhelekanga yeklasi B yokuphazamiseka kwamandla aphezulu, inkqubo yokulawula kufuneka igcine i-state-assist state okanye ubuncinane igcine i-power-assist state imizuzwana ye-30 xa isantya sesithuthi sikhulu kune-5 km / h. Ke ngoko, ngoku, iibhasi zombane ubukhulu becala zisebenzisa imowudi yolawulo lonikezelo lwamandla amabini ukukhawulelana neemfuno zolawulo. Ezinye iimoto zorhwebo zombane zilandela “i-GB 18384-2020 IiMfuno zoKhuseleko lweSithuthi soMbane.” Ukubunjwa kwenkqubo ye-EHPS yezithuthi zorhwebo kuboniswe kuMfanekiso 2. Okwangoku, zonke izithuthi ezinobunzima beetoni ze-4.5 okanye ngaphezulu ukusuka kwi-YI zisebenzisa inkqubo ye-HPS, kwaye i-chassis eyakhiwe ngokwayo igcina indawo ye-EHPS.

02 Inkqubo yokuLawula uMbane woMbane

Inkqubo ye-Electric Power Steering (EPS) yezithuthi zorhwebo ezilula kakhulu zisebenzisa i-electric circulating ball steering gear (njengoko kuboniswe kuMfanekiso 3), okuphelisa amacandelo afana nepompo yombane yombane, itanki yeoli, kunye nombhobho weoli xa kuthelekiswa nenkqubo ye-EHPS. Ineenzuzo zenkqubo elula, ubunzima obuncitshisiweyo, ukuphendula ngokukhawuleza, kunye nokulawula okuchanekileyo. Ulawulo lwamandla lutshintshiwe ukusuka kwi-hydraulic ukuya kumbane, kwaye umlawuli ulawula ngokuthe ngqo i-motor yombane ukuvelisa uncedo lwamandla. Xa umqhubi ejika isondo lokuqhuba, i-sensor idlulisela i-angle yokulawula kunye neempawu ze-torque kumlawuli. Emva kokufumana i-angle yokulawula, imiqondiso ye-torque, kunye nolunye ulwazi, umlawuli ubala kwaye akhuphe iimpawu zokulawula ukulawula i-motor yombane ukuvelisa uncedo lwamandla. Xa ivili lokuqhuba lingaguqukiyo, iyunithi yokulawula yokuncedisa amandla ayithumeli iimpawu, kwaye i-motor-assisted motor ayisebenzi. Ukubunjwa okuqhelekileyo kwenkqubo yokulawula ibhola ejikelezayo yombane kuboniswe kuMfanekiso 4. Okwangoku, i-YI isebenzisa iskimu se-EPS kwiimodeli eziziphuhlisayo ze-tonnage ezincinci.
