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>Kapangilo kakuru, na vigaŵa vyakusuzga vya mafuta ghakupangika mukati.

*Control val val core: Chigaŵa chakuzirwa, kanandi vavu ya slide panji vavu yakuzungulira. Malo ghake ghakulaŵilirika na lever yakulongozgera kwizira mu kulumikizgana kwa makina panji mafuta gha hydraulic ghakuyezga, ndipo ghakumanyiska mwaluŵiro umo chigaŵa cha mafuta chikuŵira.
*Overflow val/valve: * * Kuchepeska nkhongono yikuru ya dongosolo na kuvikilira vigaŵa vya hydraulic.
** * Wonani valsion: * * yikupangiska kuti mafuta ghawelere ku maji ndipo yikupangiska kuti munthu waŵe na nkhongono.
** * Mdoko ya draibod too too: * * Kulaŵilira umo mafuta ghakuchitira kuti ghawoneseske kuti ghakwenda makora na kuchepeska nkhongono pa nyengo ya vula. : * * Woneseskani kuti valve core yikuwelera ku malo ghambura kunjilirapo (malo ghakuwonekera panthazi) para lever yakulaŵilira yafumiskika: * * Lumikizani doko lakunjilirapo (kufuma pa pampu yakulongozgera), doko lakuwelera (tanki yakuwelera), madowoko gha mafuta ku silinda za clutch, na madowoko gha mafuta ku silinda za mabuleki gha ku mazere na ku mazere (panji nthowa yakukolerana na nthazi zakulongozgera (panji nthowa yakukolerana na mtundu wa mtundu wa mtundu zingasankhika): * * * * Mu electro-hydraulic systems systemsal systems systems, lever yakulaŵilira yingaŵa pakwamba kulaŵilira valve ya low - positi yakuyezga, ndipo pamanyuma pake valve yikuru ya valve yikulongozgeka na mafuta ghakuyezga. Fundo yakugwira ntchito: Neutrac (right): Lever yakulaŵilira yili mu malo ghapakati, ndipo valve core yili mu malo ghambura kunjilirapo. Mafuta gha nkhongono ghakukhira yayi ku silinda ya clutch (clutch yikukhala yakunjilirapo), ndiposo yikukhira yayi ku silinda la mabuleki (kufwatulika kwa mabuleki). Mafuta ghakufuma ku pampu ya mafuta ghangawelera mwaluŵiro ku thanki panji ghakuthandazgika mu nthowa yakucepa - low loading channel (kuthemba pa kapangidwe). Kulongozga (ndondo yakupukuta): Para uyo wakugwira ntchito wakukoka chigaŵa chimoza cha ndodo yakulongozgera, valve core yikusuntha, kujura dera la mafuta na kuzomerezga kuti mafuta ghakuchichizga ghanjire mu silinda yakufumiskiramo ya steering clutch ku chigaŵa chira (mbali ya kumazere), kukankhira pisitoni kuti yilekeske clutch na kudumura nkhongono ya msewu wa ku mazere. Pa nyengo yeneyiyo, nchito iyi yingaŵa yakukolerana kuti yijure chigaŵa chinyake cha mafuta (panji kwizira mu nthowa yakukolerana ya makina), kuzomerezga mafuta ghakuchichizga kuti ghanjire mu silinda ya mabuleki ku chigaŵa icho (kumanzere), kugwiriskira ncito maburaki (kanandi ghakovwira para lever yakulaŵilira yikukoleka ku chigaŵa chachiŵiri, kukwaniska kutembenuka mwaluŵiro), kusunga nkhongono pa msewu wakunyoloka, kukankhira makina kuti ghatembenuke kumazere, kufumiska lever): kufumiska lever yakulaŵilira, nyengo yakupumulira ya reset yikuzungulira valve core ku malo ghapakati, likudumura mafuta gha kufinya ku silinda yakupatukana, ndipo mafuta agho ghali mu silinda la kupatukana likufumiskikaposo ku thanki la mafuta pasi pa nchito ya clutch reset spring. Clutch yikulumikizgikaso, ndipo mafuta ghakuchichizga ku silinda ya mabuleki yikudumulika (panji nthowa ya mafuta ghakuwelera yikujulika). Buraki yikufumiskika pasi pa ivyo vikuchitika mu nyengo ya vula.

Kugwiliskira ntchito

Msonkhano wa steering valve wa bulldozer ni chigaŵa chakuzirwa chomene cha bulldozer wakulondezgapo, ndipo kugwiriskira ncito kwake kukuwoneka mwaluŵiro mu milimo yakupambanapambana ya kulongozgeka kwa bulldozer:

1. * * Kuyendeska galimoto: * * Sungani valve core mu malo ghapakati, khalani na clutches ku vigaŵa vyose viŵiri, kufwatura mabuleki ku vigaŵa vyose viŵiri, na kuyendeska msewu mwakukolerana ku vigaŵa vyose viŵiri.
2. * * Kutembenuka kwa Smomo (kuzgokera kwa radius yikuru): * * * mukolere chigaŵa chimoza cha lever ya steering (kukwanira yayi), kufumiska waka clutch ku chigaŵa icho (kwambura kugwiriskira ncito buraki). Ndege ya mbali ya nkhongono yikukankhira msewu wakupatukana panthazi kuti ufike pa kutembenukira mwambura kusuzga. Kukwaniska kusintha nthowa mu malo ghakujulika.
3. * * Kutembenuka / kutembenuka kwa siteshoni: * * Kokani chigaŵa chimoza cha lever ya steering pasi. Chakwamba, kupatuska clutch ku chigaŵa chira, na kulutilira kuyikoka kuti ziŵikepo buraki ku chigaŵa chira pamoza. Kuyendeska na nkhongono ya mzere, msewu wa pambali ukulekeskeka, ndipo makina mwaluŵiro panji mu malo ghakuzgoka pakati pa msewu wa pambali wa mabuleki. Kutengera kutembenukira panji kulinganizgika kwakukwana mu malo ghachoko waka.

4. * * Kutembenuka kwa slop: * * Kutembenukira pa msewu kukukhumbikwira kuti paŵe kulaŵilira kwakukwana, ndipo zgoro na kusalala kwa vavu yakulongozga ni vyakuzirwa chomene kuti vileke kutelera panji kutaya nkhongono.
5. * * Kugwira ntchito mwaluŵiro: * * Mu ntchito ziwemi nga ni bulldozing na kuŵika pa mlingo, kuzgoŵezga kwa nyengo yichoko waka kukukhumbikwa, ndipo kuziŵizga na kugwira ntchito kwakukhwaskana na kusunkhunyika kwa valve yakutembenukira kukukhwaska chomene mtundu na kugwira ntchito kwa ntchito.
6. * * Saki Park: * * Mu nyengo za ngozi, kukoka vingwe vyose viŵiri vyakulongozgera pasi kungapangiska kuti vigaŵa vyose viŵiri viŵe vyakugaŵikana na kuŵika mabuleki ku vigaŵa vyose viŵiri, ndipo ivi vikupangiska kuti bulldozer yileke mwaluŵiro (kweni iyi ni nthowa yakumanyikwa yayi, chifukwa mabuleki ghakuru kanandi ghakuŵa na ndondomeko yapadera). Mfundo yikuru ya kugwira ntchito: * * Kuzindikira, kusalala, na kugomezgeka kwa steering vikuthemba chomene pa kapangidwe na udindo wa vavu ya steering.
*Dindo la kugomezgeka:: * * Kutondeka kwa ndondomeko kungapangiska kuti bulldozer yileke kulaŵilira, iyo njakofya chomene. Kudindika, kuvula, na nkhongono yakulimbana na kufipiskika kwa vavu yakulongozgera nkhwakuzirwa comene.
*Kuwonjezera nkhongono: Kulota na steering yakugwira ntchito makora kukuchepeska kutaya kwa nkhongono na kutaya nyengo.
*Driver kutopa: Kutopa, kukhomeka, panji kulongozgeka kwambura kuzgora kungapangiska kuti dalayivara waŵe na katundu wakugwira ntchito na kutopa.
