EPS vs. EHPS: Kumvetsetsa Maukadaulo Awiri Ofunikira Oyendetsera Mphamvu Zamagetsi

Mu magalimoto amakono, makina oyendetsera magetsi alowa m'malo mwa chithandizo chachikhalidwe cha hydraulic. Pali njira ziwiri zazikulu zothetsera vutoli: EPS (Electric Power Steering) ndi EHPS (Electro-Hydraulic Power Steering). Ngakhale kuti zonsezi zimathandizidwa ndi magetsi, zimasiyana kwambiri pa kapangidwe, magwiridwe antchito, ndi kagwiritsidwe ntchito.

Momwe EPS ndiEPPSNtchito

EPS imadalira kwambiri mota yamagetsi kuti ipereke chithandizo chowongolera. Dalaivala akatembenuza gudumu, chowunikira mphamvu yamagetsi chimazindikira cholowera, ndipo chipangizo chowongolera zamagetsi (ECU) chimawerengera mphamvu yothandizira yofunikira kutengera liwiro la galimoto, kenako chimalamula mota kuti ichitepo kanthu mwachindunji. EPS imagwiritsa ntchito mphamvu pokhapokha ngati chiwongolero chikufunika.

EHPS (chiwongolero chamagetsi cha hydraulic), kumbali ina, ndi kusintha kwa chiwongolero champhamvu cha hydraulic (HPS). M'malo moyendetsedwa ndi injini, pampu yake ya hydraulic imayendetsedwa ndi mota yamagetsi. Kenako pampuyo imapereka madzi a hydraulic ku chiwongolero, kupereka chithandizo chomwe chingasinthidwe ndi liwiro la galimoto—lopepuka pa liwiro lotsika komanso lolimba pa liwiro lalikulu.

Kusiyana Kwakukulu Pakati pa EPS ndiPumpu Yoyendetsera Mphamvu ya Hydraulic yamagetsi

EPS ili ndi kapangidwe kosavuta, kochotsa mapampu a hydraulic, malo osungiramo madzi, ndi mapaipi. Izi zimapangitsa kuti mphamvu zigwiritsidwe ntchito bwino kwambiri (zoposa 90%) komanso kuti mphamvu zisungidwe ndi pafupifupi 85% poyerekeza ndi HPS. Imagwira ntchito mwakachetechete ndipo siifuna kukonzedwa. Komabe, thandizo lake lamagetsi lokha lingamveke ngati "lachilengedwe" kwa oyendetsa ena ndipo lingathe kuchepetsedwa akamanyamula katundu wolemera.

EHPS imasunga zida zamagetsi, zomwe zimapangitsa kuti isamagwire bwino ntchito (60-70%) komanso isamagwiritse ntchito mphamvu nthawi zonse ngakhale isanayendetsedwe. Imapanganso phokoso la pampu ndipo imafunika kusintha madzi nthawi ndi nthawi. Komabe imapereka mphamvu yolimba komanso kumva bwino pamsewu, zomwe zimapangitsa kuti ikhale yoyenera magalimoto akuluakulu ogulitsa.

Mapulogalamu ndi Zochitika za EPS ndi EHPS

EPS ikutsogolera magalimoto okwera anthu ndi magalimoto atsopano amphamvu, ndipo ili ndi 99.91% ya msika wa magalimoto okwera anthu ku China wa NEV mu 2020.

Pumpu Yoyendetsera Galimoto Yamagetsi Yamalonda, yokhala ndi pafupifupi 40.1% ya msika woyendetsa magalimoto amalonda ku China m'chaka chomwecho, ikupitirirabe kukhala yolimba m'malole ndi mabasi komwe mphamvu zothandizira kwambiri ndizofunikira. Pamene magalimoto atsopano amagetsi akuchulukirachulukira, EHPS imapindula ndi mabatire amphamvu omwe ali m'galimoto omwe amayatsa mapampu akuluakulu amagetsi, zomwe zimaonetsetsa kuti akupitilizabe kukhala ofunika.

Matekinoloje onsewa akupitilizabe kusintha, pomwe EPS ikupita patsogolo kupita ku waya woyendetsedwa ndi waya ndi EHPS ikusintha kukhala malo olumikizirana magalimoto amagetsi ndi a hybrid.

NF GROUP (yomwe idakhazikitsidwa mu 1993, mafakitale 6) ndi kampani yofunika kwambiri yogulitsa zinthu za NEV ku China komanso kampani yodziwika bwino yogulitsa magalimoto ankhondo aku China, yomwe imaperekachotenthetsera choziziritsira chamagetsi champhamvus, pompu yamadzi yamagetsis, BTMS, ma compressor amagetsi a mpweya, EPS, EHPS, ma compressor amagetsi a A/C, ma valve atatu, ma heaters oimika magalimoto/AC, ma plate heat exchangers, ndi zina zotero.

Timalandira mafunso ochokera kwa makasitomala omwe alipo komanso atsopano. Chonde titumizireni uthenga kuti mukambirane za zosowa za polojekiti yanu kapena pemphani pepala lazidziwitso laukadaulo mwatsatanetsatane.
