Zaka makumi awiri{{0}zisanu} zapitazo, kuzindikira zovuta za chiwongolero cha magetsi inali ntchito yosavuta. Mavutowa makamaka amabwera pa "matenda am'mawa" omwe amawonedwa m'magalimoto ozizira. Komabe, mawonekedwe agalimoto asintha kwambiri poyambitsa liwiro-ndi chiwongolero chovutirapo, chiwongolero chamagetsi, ndi zowongolera zamakompyuta zapamwamba. Kupita patsogolo kumeneku kwawonjezera zovuta pakuwunika kwa chiwongolero chamagetsi, zomwe zimafuna njira yowonjezereka.
Mitundu Iwiri Yamachitidwe Owongolera Mphamvu:
Hydraulic Cylinder Yolumikizidwa ku Drag Link:
Mumtundu uwu, silinda ya hydraulic imamangiriridwa ku ulalo wokoka ndi chassis. Valavu yowongolera imalowetsa kumapeto kwa ndodo, yolumikizidwa ndi ulalo wokokera, ndipo cholumikizira cha valve chimalumikizidwa ndi mkono wa pitman.
Hydraulic Cylinder Integral to Steering Gear:
Mtundu wachiwiri umaphatikizapo hydraulic cylinder yophatikizika ndi zida zowongolera, zolumikizidwa ndi nati ya mpira wobwereza pa shaft yowongolera. Valve yowongolera yozungulira imalumikizidwa ndi torsion bar pa shaft yowongolera.
M'mitundu yonse iwiri, pampu imapereka madzimadzi ku valve yolamulira, yomwe imayang'anira kuthamanga kwa mpweya kupita ndi kuchoka ku silinda ya hydraulic potengera zomwe zimachokera ku mkono wa pitman kapena shaft.
Evolution of Control Systems:
Kusintha kwa machitidwe owongolera mphamvu kunapangitsa kuti pakhale makina a electronic variable orifice (EVO) m'ma 1980s. Makinawa anali ndi cholinga chochepetsa-kukhudzika kwachangu ndikuwongolera kuwongolera. Valavu ya EVO, yomwe imayikidwa pa mpope wowongolera mphamvu, imagwiritsa ntchito chowongolera chamagetsi kuti ipangitse kusintha kwa maginito mu koyilo yake ya solenoid.
Udindo wa Electronic Controller ndi Speed Sensor:
Controller ntchito:
Woyang'anira pakompyuta amasintha chiwongolero kutengera zolowetsa kuchokera ku liwiro lagalimoto komanso malo owongolera. Imakwaniritsa izi potumiza voteji ya pulse wide modulated (PWM) ku coil ya solenoid.
Kulowetsa Liwiro Lagalimoto:
Kulowetsa liwiro lagalimoto nthawi zambiri kumachokera ku gawo lowongolera injini, kulola makinawo kuti asinthe chiwongolero chotengera momwe magalimoto amayendera.
Sensor Speed Wheel Speed (HWSS):
HWSS imayesa liwiro lomwe chiwongolero chimatembenuzidwira, kupereka chizindikiro chosinthika cha analogi kwa wowongolera. Chizindikiro ichi, kuyambira kumtunda mpaka kutsika kwamagetsi, kumathandizira kuwongolera bwino.
Zolephera ndi Zotsatira zake:
Kulephera kwa EVO Valve Coil:
Ngati koyilo mu valavu ya EVO ikalephera, pampu yowongolera mphamvu ipereka mphamvu zonse ndi voliyumu ku silinda ya hydraulic, zomwe zimapangitsa kuti chiwongolero chiwonjezeke pamayendedwe onse.
Kulephera Kwakasinthidwe ka EVO Valve:
Kulephera kwa malo otsekedwa kwa valavu ya EVO kudzafuna khama kuti ayendetse galimotoyo, chifukwa padzakhala chithandizo chochepa kapena palibe.
Kulephera kwa Sensor:
Kulephera kwa sensa, makamaka mu HWSS, kungayambitse zovuta zapakatikati. Kusiyanasiyana kwa ma voliyumu opangidwa ndi sensor ndikofunikira kuti wowongolera asinthe chiwongolero chake molondola.
Pomaliza, mphamvu zowongolera mphamvu zasintha kwambiri, zomwe zimafunikira kumvetsetsa bwino za machitidwe owongolera pakompyuta ndi zolowetsa sensa kuti azindikire bwino. Magalimoto akamapitilirabe kupita patsogolo, kudziwa zaukadaulo waukadaulo ndikofunikira kwa akatswiri amagalimoto kuti awonetsetse kudalirika komanso magwiridwe antchito oyenera amagetsi owongolera pamagalimoto osiyanasiyana.
