01 Electric Hydraulic Power Steering System

Monga momwe tawonetsera pa Chithunzi 1, dongosolo la Electric Hydraulic Power Steering (EHPS) limapangidwa ndi hydraulic power steering (HPS) ndi galimoto yamagetsi, yomwe imathandizira mawonekedwe oyambirira a HPS system. Dongosolo la EHPS ndiloyenera pamagalimoto opepuka, apakatikati, ndi olemetsa, komanso makochi apakatikati ndi akulu. Ndikukula mwachangu kwa magalimoto ogulitsa mphamvu zatsopano (monga mabasi, mayendedwe, ndi ukhondo), gwero lamphamvu la pampu yamagetsi yamtundu wa hydraulic power steering system yasintha kuchoka pa injini kupita ku mota, ndipo kachitidwe ka batire lamphamvu kwambiri pagalimoto imapangitsa kuti zitheke kugwiritsa ntchito pampu yamagetsi yamphamvu kwambiri. Dongosolo la EHPS limatanthawuza njira yoyendetsera mphamvu ya hydraulic yomwe imagwiritsa ntchito pampu yamagetsi yamphamvu kwambiri.

Pamene nkhawa ya dziko lonse pa chitetezo ndi khalidwe la magalimoto amphamvu zatsopano zikuwonjezeka, mulingo wovomerezeka wadziko lonse "GB38032-2020 Electric Bus Safety Requirements" unaperekedwa pa May 12, 2020. Ndime 4.5.2 inawonjezera zofunikira zoyendetsera dongosolo lothandizira mphamvu poyendetsa galimoto. Ndiko kuti, panthawi yoyendetsa galimoto, pamene galimoto yonse ikukumana ndi vuto lachilendo la kusokonezeka kwa mphamvu ya kalasi B yamphamvu kwambiri, chowongoleracho chiyenera kukhala ndi mphamvu zothandizira mphamvu kapena kukhala ndi mphamvu zothandizira mphamvu kwa masekondi a 30 pamene liwiro la galimoto ndi lalikulu kuposa 5 km / h. Chifukwa chake, pakadali pano, mabasi amagetsi nthawi zambiri amagwiritsa ntchito njira ziwiri zowongolera magetsi kuti akwaniritse zofunikira. Magalimoto ena amagetsi amagetsi amatsata "GB 18384-2020 Zofunikira Zotetezera Galimoto Yamagetsi." Mapangidwe a dongosolo la EHPS la magalimoto amalonda akuwonetsedwa mu Chithunzi 2. Pakalipano, magalimoto onse omwe ali ndi kulemera kwa matani a 4.5 kapena kuposerapo kuchokera ku YI amagwiritsa ntchito dongosolo la HPS, ndipo galimoto yodzipangira yokha imasungira malo a EHPS.

02 Electric Power Steering System

Dongosolo la Electric Power Steering (EPS) la magalimoto oyendetsa magalimoto opepuka nthawi zambiri amagwiritsa ntchito zida zoyendetsera mpira zozungulira (monga momwe tawonetsera pa Chithunzi 3), zomwe zimachotsa zinthu monga pampu yamagetsi yamagetsi, thanki yamafuta, ndi chitoliro chamafuta poyerekeza ndi dongosolo la EHPS. Lili ndi ubwino wa dongosolo losavuta, kuchepetsa kulemera, kuyankha mofulumira, ndi kulamulira kolondola. Chiwongolero champhamvu chasinthidwa kuchoka ku hydraulic kupita kumagetsi, ndipo wowongolera amawongolera mwachindunji mota yamagetsi kuti apange thandizo lamagetsi. Dalaivala akatembenuza chiwongolero, sensa imatumiza kolowera ndi ma torque kwa wowongolera. Atalandira chiwongolero chowongolera, ma torque, ndi zidziwitso zina, wowongolera amawerengera ndikutulutsa zidziwitso zowongolera kuti aziwongolera mota yamagetsi kuti apange thandizo lamagetsi. Pamene chiwongolero sichinatembenuzidwe, chiwongolero chothandizira mphamvu sichitumiza zizindikiro, ndipo injini yothandizira mphamvu siigwira ntchito. Zomwe zimagwiritsidwa ntchito pamagetsi oyendetsa mpira wozungulira mpira zikuwonetsedwa mu Chithunzi 4. Pakalipano, YI imagwiritsa ntchito ndondomeko ya EPS ya zitsanzo zazing'ono za tonnage.
