Sib tham txog Kev Siv Cov Khoom Siv Hluav Taws Xob Txhuam Hniav hauv Automotive EPS (1)

Lub npe tag nrho ntawm EPS yog Electronic Power Steering, tseem hu ua Electronic Power Steering, uas siv lub zog tsim los ntawm lub tshuab hluav taws xob los pab cov neeg tsav tsheb hauv lub zog tsav. Lub steering system, uas yog ib qho tseem ceeb ntawm tag nrho lub tsheb, yog ib qho ntawm cov txheej txheem tseem ceeb uas cuam tshuam rau kev tuav ruaj khov, kev nplij siab, thiab kev nyab xeeb ntawm lub tsheb.
Hauv kev tsim lub hauv paus, txhawm rau txhawm rau txo qhov tsis sib xws ntawm lub tsheb kauj vab txav tau yooj yim thiab lub zog ntawm lub kauj tsheb, feem ntau cov tsheb lag luam thiab 50 feem pua ​​​​ntawm cov sedans siv lub hwj chim steering systems. Txij li thaum xyoo 1950, lub hwj chim steering system tau dhau los ntawm peb theem kev loj hlob: cov pa hydraulic zog steering system (HPS), electro-hydraulic hwj chim steering system (EHPS), thiab hluav taws xob lub hwj chim steering system (EPS), thiab muaj ib tug qauv ntawm hluav taws xob. thiab kev txhim kho ntse.
Los ntawm kev xav thoob ntiaj teb, EPS kev thauj khoom ntawm lub tsheb tau tshaj 50 feem pua. Txog 63 feem pua ​​​​ntawm cov tsheb hauv Suav teb siv HPS rau cov neeg caij tsheb siv, thiab kwv yees li 35 feem pua ​​​​tau siv EPS. Txawm li cas los xij, EPS thauj khoom tus nqi ntawm cov tsheb hom tsheb hauv Suav teb tsuas yog kwv yees li 20 feem pua, qhia tias muaj peev xwm loj rau kev loj hlob yav tom ntej. Txij li xyoo 2015, Tuam Tshoj tau dhau los ntawm Tebchaws Europe, Amelikas, thiab Nyij Pooj los ua EPS kev lag luam loj tshaj plaws hauv ntiaj teb.
Kev sib xyaw ntawm EPS system
Raws li lub hauv paus ntawm cov txheej txheem kev tswj hwm ib txwm muaj, EPS lub zog hluav taws xob lub zog siv lub tshuab hluav taws xob siv hluav taws xob tswj hluav taws xob los tsim cov khoom siv hluav taws xob sib txuas ntawm qhov loj me thiab kev taw qhia los ntawm lub tshuab hluav taws xob raws li cov cim torque ntawm lub kauj thiab lub tsheb ceev cov cim, pab tus neeg tsav tsheb hauv lub kauj. kev ua haujlwm. Nws tuaj yeem yooj yim muab kev pabcuam sib txawv rau lub tshuab hluav taws xob ntawm qhov sib txawv ntawm qhov sib txawv, kom ntseeg tau tias lub tsheb yog lub teeb thiab hloov tau thaum tig ntawm qhov qis qis, muaj kev txaus siab thaum tig ntawm kev kub ceev, thiab ruaj khov thiab txhim khu kev qha.
Txawm hais tias cov qauv ntawm cov tsheb sib txawv yog qhov sib txawv, cov qauv ntawm EPS system feem ntau yog tib yam. Nws feem ntau yog tsim los ntawm lub torque (steering) sensor, hluav taws xob tswj chav tsev, hluav taws xob lub cev muaj zog, reducer, mechanical steering gear, thiab roj teeb fais fab mov.
