Chitoliro cha mafuta cha giya yoyendetsera - kumbuyo - chassis yotsika
Mtundu wa zida zowongolera
Kawirikawiri amagwiritsidwa ntchito ndi mtundu wa rack ndi pinion, mtundu wa crank pin wa nyongolotsi ndi mtundu wa mpira wozungulira.
[1] 1) Chiwongolero cha raki ndi pinion: Ndi chiwongolero chodziwika kwambiri. Kapangidwe kake koyambira ndi awiriawiri ophatikizana a pinion ndi rack. Pamene shaft yowongolera ikuyendetsa pinion kuti izungulire, rack imasuntha molunjika. Nthawi zina, chiwongolero chimatha kuzunguliridwa poyendetsa mwachindunji ndodo yomangira pafupi ndi rack. Chifukwa chake, iyi ndi giya yowongolera yosavuta. Ili ndi ubwino wa kapangidwe kosavuta, mtengo wotsika, chiwongolero chosavuta, kukula kochepa, ndipo imatha kuyendetsa mwachindunji ndodo yomangira. Imagwiritsidwa ntchito kwambiri m'magalimoto.
2) Chida chowongolera cha crankpin cha nyongolotsi: Ndi chida chowongolera chomwe nyongolotsi imakhala ngati gawo logwira ntchito ndipo crankpin imakhala ngati wotsatira. Nyongolotsi ili ndi ulusi wa trapezoidal, ndipo pin ya chala chopindika ngati chala imathandizidwa pa crank ndi bearing, ndipo crank imalumikizidwa ndi steering rocker shaft. Ikatembenuka, nyongolotsi imazunguliridwa ndi chiwongolero, ndipo pin ya chala chopindika yomwe imayikidwa mu spiral groove ya nyongolotsi imazungulira yokha, uku ikupanga kuzungulira kuzungulira steering rocker shaft, motero imayendetsa crank ndi steering drop arm kuti igwedezeke, kenako kudzera mu steering transmission mechanism kuti chiwongolero chisinthe. Mtundu uwu wa zida zowongolera nthawi zambiri umagwiritsidwa ntchito pamagalimoto okhala ndi mphamvu yayikulu yowongolera.
3) Chiwongolero cha mpira chozungulira: makina owongolera mphamvu ya mpira wozungulira [2] Kapangidwe kake kamakhala ndi magawo awiri: gawo la makina ndi gawo la hydraulic. Gawo la makina limapangidwa ndi chipolopolo, chivundikiro cham'mbali, chivundikiro chapamwamba, chivundikiro chapansi, screw ya mpira wozungulira, rack nut, rotary valve spool, fan gear shaft. Pakati pawo, pali mawiri awiri a ma transmission: awiriawiri ndi screw rod ndi nut, ndipo awiriawiri ndi rack, tooth fan kapena fan shaft. Pakati pa screw rod ndi rack nut, pali mipira yachitsulo yozungulira yozungulira, yomwe imasintha sliding friction kukhala roll friction, motero imapangitsa kuti transmission igwire bwino ntchito. Ubwino wa steering gear iyi ndikuti ndi yosavuta kugwiritsa ntchito, siigwira ntchito kwambiri komanso imakhala nthawi yayitali. Choyipa chake ndichakuti kapangidwe kake ndi kovuta, mtengo wake ndi wokwera, ndipo mphamvu ya steering siili bwino ngati rack ndi pinion.
