Nkhani - Ukadaulo wogwiritsa ntchito chiwongolero ndi waya wa chassis-2

01 Dongosolo Loyendetsera Mphamvu ya Hydraulic Yamagetsi

Monga momwe zasonyezedwera pa Chithunzi 1, dongosolo la Electric Hydraulic Power Steering (EHPS) limapangidwa ndi hydraulic power steering (HPS) ndi mota yamagetsi, yomwe imathandizira mawonekedwe oyambilira a HPS system. Dongosolo la EHPS ndi loyenera magalimoto opepuka, apakatikati, komanso olemera, komanso ma coach apakati ndi akulu. Chifukwa cha chitukuko chachangu cha magalimoto atsopano ogulitsa mphamvu (monga mabasi, logistics, ndi ukhondo), gwero la mphamvu la hydraulic power steering system yachikhalidwe lasintha kuchoka pa injini kupita ku mota, ndipo batire yamagetsi amphamvu kwambiri pagalimoto imapangitsa kuti zikhale zotheka kugwiritsa ntchito hydraulic power steering. Dongosolo la EHPS limatanthauza hydraulic power steering system yomwe imagwiritsa ntchito hydraulic power steering pump.

Pamene nkhawa ya dziko lonse yokhudza chitetezo ndi ubwino wa magalimoto atsopano amphamvu ikukwera, muyezo wofunikira wa dziko lonse wa "GB38032-2020 Electric Bus Safety Requirements" unaperekedwa pa Meyi 12, 2020. Gawo 4.5.2 linawonjezera zofunikira zowongolera makina othandizira magetsi panthawi yoyendetsa. Izi zikutanthauza kuti, panthawi yoyendetsa galimoto, pamene galimoto yonse ikukumana ndi vuto la kusokonezeka kwa mphamvu yamagetsi ya kalasi B, makina owongolera ayenera kukhala ndi mphamvu yothandizidwa kapena osachepera kukhala ndi mphamvu yothandizidwa kwa masekondi 30 pamene liwiro la galimoto lili lalikulu kuposa 5 km/h. Chifukwa chake, pakadali pano, mabasi amagetsi nthawi zambiri amagwiritsa ntchito njira yowongolera magetsi yamagetsi awiri kuti akwaniritse zofunikira zoyang'anira. Magalimoto ena amagetsi amatsatira "GB 18384-2020 Electric Vehicle Safety Requirements." Kapangidwe ka makina a EHPS a magalimoto amalonda kakuwonetsedwa pa Chithunzi 2. Pakadali pano, magalimoto onse olemera matani 4.5 kapena kuposerapo kuchokera ku YI amagwiritsa ntchito makina a HPS, ndipo chassis yodzipangira yokha imasunga malo a EHPS.

02 Dongosolo Lowongolera Mphamvu Yamagetsi

Dongosolo la Electric Power Steering (EPS) la magalimoto amalonda opepuka limagwiritsa ntchito zida zoyendetsera mpira zamagetsi (monga momwe zasonyezedwera pa Chithunzi 3), zomwe zimachotsa zinthu monga pampu yamagetsi ya hydraulic, thanki yamafuta, ndi chitoliro chamafuta poyerekeza ndi dongosolo la EHPS. Lili ndi ubwino wa dongosolo losavuta, kulemera kochepa, kuyankha mwachangu, komanso kuwongolera molondola. Chiwongolero chamagetsi chasinthidwa kuchoka pa hydraulic kupita ku magetsi, ndipo chowongolera chimayang'anira mwachindunji mota yamagetsi kuti chipange chithandizo chamagetsi. Dalaivala akatembenuza chiwongolero, sensa imatumiza ngodya yowongolera ndi zizindikiro za torque kwa wowongolera. Atalandira ngodya yowongolera, zizindikiro za torque, ndi zina zambiri, wowongolera amawerengera ndikutulutsa zizindikiro zowongolera kuti alamulire mota yamagetsi kuti apange chithandizo chamagetsi. Ngati chiwongolero sichikuzunguliridwa, gawo lowongolera lowongolera lothandizidwa ndi mphamvu silitumiza zizindikiro, ndipo mota yothandizidwa ndi mphamvu sigwira ntchito. Kapangidwe kofala ka dongosolo loyendetsa mpira wamagetsi lozungulira likuwonetsedwa pa Chithunzi 4. Pakadali pano, YI imagwiritsa ntchito njira ya EPS ya mitundu yaying'ono yopangidwa yokha.
