Core function: Control the disengagement and engagement of the steering clutch: * * This is its main function. By controlling the flow of hydraulic oil to the steering clutch cylinder, the separation (cutting off the power of the track on that side) or engagement (transmitting power) of one or both clutches can be achieved. Control the application and release of the steering brake: * * When a sharp turn or stationary steering is required, this valve usually interlocks to control the brake on that side (the track side with the clutch disengaged), braking the driving wheel of that side track and causing the machine to rotate around the center of that side track. Implementing "single lever" steering operation: Modern bulldozers typically use a single joystick to control steering. Pull the lever backwards to disengage the clutch (start turning), and continue pulling backwards to apply the brake in conjunction (sharp turn). Release the control lever to automatically reset, clutch engaged, brake released, and resume straight travel. The complex oil circuit design inside the steering valve assembly realizes this operating logic. Structural composition: Valve body>Main kapangidwe, ndi ndime zovuta mafuta kukonzedwa mkati.

*Control valve core: Chigawo chapakati, nthawi zambiri valavu yolowera kapena valavu yozungulira. Malo ake amawongoleredwa ndi chiwongolero chowongolera kudzera pamakina olumikizirana kapena oyendetsa ma hydraulic oyendetsa, ndikuwunikira komwe akuzungulira mafuta.
* Valavu yowonongeka / chitetezo: * * Imachepetsa kuthamanga kwakukulu kwa dongosolo ndikuteteza zigawo za hydraulic.
** * Chongani valve: * * imalepheretsa mafuta kubwerera kumbuyo ndikusunga kupanikizika.
** * Bowo la Throttle/damping hole: * * Yang'anirani kuchuluka kwa mafuta kuti muwonetsetse kuti chiwongolero chikuyenda bwino ndikuchepetsa kukhudzidwa pakukhazikitsanso kasupe. : * * Onetsetsani kuti chiwongolero cha valve chimabwereranso kumalo osalowerera ndale (kutsogolo kutsogolo) pamene lever yolamulira imatulutsidwa: * * Lumikizani khomo lolowera (kuchokera pa mpope woyendetsa), doko lobwerera (thanki yobwerera), madoko a mafuta kumanzere ndi kumanja kwazitsulo zowongolera zowongolera, ndi madoko amafuta kumanzere ndi kumanja ma cylinders a brake (kapena cholumikizira cholumikizira chamagetsi mu valavu yamagetsi{{} * * * * * * * * * *) Machitidwe oyendera bwino kapena okhudzidwa ndi katundu, chowongolera chikhoza kuwongolera kaye -vavu yoyendetsa ndege yotsika, kenako valavu yayikulu imayendetsedwa ndi mafuta oyendetsa. Mfundo yogwira ntchito: Kusalowerera ndale (yowongoka): Chingwe chowongolera chili pakatikati, ndipo nsonga ya valve ili m'malo osalowerera ndale. Mafuta opanikizika samayenderera ku clutch cylinder (clutch imakhalabe yogwira ntchito), komanso samayenderera ku silinda ya brake (brake release). Mafuta ochokera ku mpope wamafuta akhoza kubwezeredwa ku thanki kapena kuzunguliridwa kudzera panjira yotsika-yotsika kwambiri (kutengera kapangidwe kake). Chiwongolero (chikoka ndodo): Pamene woyendetsa amakoka mbali imodzi ya chiwongolero, phala la valve limayenda, kutsegula dera la mafuta ndikulola kuti mafuta alowetsedwe mu silinda yotulutsa chowongolera kumbaliyo (kumanzere), kukankhira pisitoni kuti athetse clutch ndikudula mphamvu ya njanji yakumanzere. Nthawi yomweyo, izi zitha kulumikizidwa kuti mutsegule dera lina lamafuta (kapena kudzera pamakina olumikizirana), kulola mafuta kuti alowe mu silinda ya brake kumbali iyo (mbali yakumanzere), gwiritsani ntchito braking (nthawi zambiri imagwira ntchito ngati chowongolera chowongolera chimakokera ku theka lachiwiri, kukwaniritsa kutembenuka mwachangu), kukhalabe ndi mphamvu panjira yakumanja, kukankhira makinawo kuti atembenukire kumanzere, yambitsaninso (kutulutsanso valavu) Pamalo apakati, amadula mafuta oponderezedwa kupita ku silinda yolekanitsa, ndipo mafuta omwe ali mu silinda yolekanitsa amatulutsidwanso ku thanki yamafuta potengera kasupe woyambitsanso clutch. Clutch imalumikizidwanso, ndipo mafuta opanikizika ku silinda ya brake amadulidwa (kapena njira yamafuta yobwerera imatsegulidwa). Brake imatulutsidwa pansi pa machitidwe a reset spring.

Kugwiritsa ntchito

Gulu la valavu lowongolera la bulldozer ndi gawo lofunika kwambiri la bulldozer yotsatiridwa, ndipo kagwiritsidwe ntchito kake kakuwoneka mwachindunji pakuwongolera kosiyanasiyana kwa bulldozer:

1. * * Kuyendetsa molunjika: * * Sungani phata la valve pamalo apakati, gwirani zokopa kumbali zonse ziwiri, masulani mabuleki kumbali zonse ziwiri, ndikuyendetsa njanji mofanana kumbali zonse ziwiri.
2. * * Kutembenuka kosalala (kutembenuka kwakukulu kozungulira): * * Kokani pang'onopang'ono mbali imodzi ya chiwongolero chowongolera (osati mokwanira), ingotulutsani chingwe kumbaliyo (popanda kuphwanya brake). Njira yam'mbali yamphamvu imakankhira njira yolekanitsa kutsogolo kuti ikwaniritse kutembenuka kosalala. Zoyenera kusintha njira m'malo otseguka.
3. * * Kutembenukira chakuthwa/kuima: * * Kokani mbali imodzi ya chiwongolero mpaka pansi. Choyamba, chotsani clutch kumbaliyo, ndipo pitirizani kukoka kuti mugwiritse ntchito brake kumbaliyo molumikizana. Poyendetsedwa ndi njanji yam'mbali yamagetsi, njanji yam'mbali yama braking imayimitsidwa, ndipo makinawo mwachangu kapena m'malo mwake amatembenuka mozungulira pakati pa njanjiyo. Oyenera kutembenuka kapena kuyanjanitsa bwino m'malo opapatiza.

4. * * Kutembenuza kotsetsereka: * * Kutembenuza malo otsetsereka kumafuna kuwongolera kolondola, ndipo kuyankhidwa ndi kusalala kwa valavu ya chiwongolero n’kofunika kwambiri kuti tipewe kutsetsereka kapena kutaya mphamvu.
5. * * Opaleshoni yolondola: * * Muzochita zabwino monga bulldozing ndi kusanja, nthawi zambiri kuwongolera kozungulira kwazing'ono kumafunika, ndipo kukhudzidwa ndi kayendedwe ka micro motion ka valve yotembenuza kumakhudza mwachindunji ubwino ndi mphamvu ya ntchitoyo.
6. * * Kuyimitsa Magalimoto Otetezeka: * * Muzochitika zadzidzidzi, kukokera zitsulo zonse ziwiri zowongolerera pansi kungathe kuchotsa mwamsanga zowomba mbali zonse ziwiri ndi kuika mabuleki kumbali zonse ziwiri, kuchititsa kuti bulldozer iime mofulumira (koma iyi si njira yachizolowezi yoboola, chifukwa brake yaikulu nthawi zambiri imakhala ndi dongosolo losiyana). Pakatikati pa magwiridwe antchito: * * Kukhudzika, kusalala, komanso kulondola kwa chiwongolero zimatengera kapangidwe ndi mawonekedwe a valavu yowongolera.
*Kiyi yodalirika: * * Kulephera kwa chiwongolero kungapangitse bulldozer kulephera kuwongolera, zomwe ndizowopsa kwambiri. Kusindikiza, kukana kuvala, komanso kuthekera koletsa kuyipitsa kwa valve yowongolera ndikofunikira.
*Kukhudza kwachangu: Kuwongolera kosalala komanso kothandiza kumachepetsa kutayika kwa mphamvu komanso kuwononga nthawi.
*Kutopa kwa madalaivala: Kuwongoleredwa kolemera, kokakamira, kapena kusalabadira kumatha kuwonjezera kulemedwa ndi kutopa kwa dalaivala.
