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>Chimiro chikuru, chine mafuta akaoma mavhesi akagadziriswa mukati.

*Kudzora vharafu musimboti: Iyo yakakosha chikamu, kazhinji slide vharafu kana inotenderera vharafu. Chinzvimbo chayo chinodzorwa neinotungamira lever kuburikidza ne mechaniki yekubatanidza kana mutyairi we hydraulic oiri, ichinyatso tarisa kwainoenda kudunhu reoiri.
* Overflow valve/safety valve: * * Inodzikamisa kudzvinyirira kwakanyanya kweiyo system uye inodzivirira hydraulic components.
** * Cheki vharafu: * * inodzivirira mafuta kumashure uye inochengetedza kudzvanywa.
** * Throttle gomba / damping gomba: * * Dzora mwero wekuyerera kwemafuta kuti uve nechokwadi chekutungamira uye kuderedza kukanganiswa pachitubu chekuseta. : * * Iva nechokwadi chokuti chivharo chevhavha chinongodzokera panzvimbo isina kwazvakarerekera (yakananga mberi chinzvimbo) kana chivharo chekudzora chikasunungurwa: * * Batanidza chiteshi chekupinda (kubva papombi inotungamira), chiteshi chekudzoka (tangi rekudzoka), zviteshi zvemafuta kuruboshwe uye kurudyi zvidhinha clutch cylinders, uye zviteshi zvemafuta kuruboshwe uye kurudyi mabhureki cylinders (kana kuti linkage mechanismau control valve In hydrlic valve inogona kusarudzwa{{} * proportional or load sensitive systems, control lever inogona kutanga yadzora yakaderera-pressure pilot valve, uye ipapo main valve core inofambiswa nepilot oil. Kushanda musimboti: Neutral (yakatwasuka): Iyo yekudzora lever iri pakati pechinzvimbo, uye iyo vheji yepakati iri munzvimbo isina kwayakarerekera. Oiri yekumanikidza haiyerere ichienda kune clutch cylinder (clutch inoramba yakabatikana), uye haiyerera ichienda kune brake cylinder (brake release). Oiri inobva papombi yeoiri inogona kudzoserwa mutangi kana kuti kutenderedzwa negwara rinodzikira-zvichienderana nemagadzirirwo acho. Kutungamira (kudhonza tsvimbo): Kana mutyairi achikwevera rumwe rutivi rwechidhiraivho, simbi yevharuvhu inofamba, ichivhura dunhu reoiri uye ichibvumira mafuta ekumanikidza kuti apinde muhumburumbira wekuburitsa weiyo clutch yekutungamirira kune rumwe rutivi (kuruboshwe), achisundira piston kuti abvise clutch uye abvise simba renzira yekuruboshwe. Panguva imwecheteyo, chiito ichi chinogona kubatanidzwa kuvhura imwe dunhu remafuta (kana kuburikidza ne mechanic linkage mechanism), ichibvumira mafuta ekumanikidza kupinda mubrake cylinder kudivi iro (kuruboshwe), shandisa braking (inowanzo shanda kana iyo control lever inodhonzwa kune yechipiri hafu, ichiita nekukurumidza kutendeuka), chengetedza simba munzira yekurudyi, sunda muchina kuti utendeuke kuruboshwe, reset (kusunungura chitubu chekuvhara) kunzvimbo yepakati, inocheka mafuta ekumanikidza kune silinda yekuparadzanisa, uye mafuta ari muhumburumbira wekuparadzanisa anoburitswa achidzokera kutangi remafuta pasi pechiito che clutch reset chitubu. Iyo clutch inobatanidzwazve, uye mafuta ekumanikidza kune brake cylinder anogurwa (kana kuti nzira yemafuta yekudzoka inovhurwa). Iyo bhureki inoburitswa pasi pechiito chekugadzirisa chitubu.

Application

Iyo dhizaini yevharuvhu yekubatanidza yebulldozer chinhu chinonyanya kukosha cheiyo bulldozer inotevedzwa, uye mashandisirwo ayo anoratidzwa zvakananga mukuita kwakasiyana siyana kwebulldozer:

1. * * Kutyaira kwakarurama: * * Chengetedza chivharo chevhavha panzvimbo yepakati, shandisa mabhanhire kumativi ose, sunungura mabhureki kumativi ose maviri, uye tyaira njanji synchronously kumativi ose maviri.
2. * * Smooth turning (rarge radius turn): * * Dhonza zvinyoro-nyoro rutivi rumwe rwechitsigiro (kwete zvizere), ingosunungura clutch kurutivi irworwo (pasina kushandisa bhureki). Iyo simba redivi track inosundira yekuparadzanisa yedivi track kumberi kuti iwane kutendeuka kwakatsetseka. Inokodzera kugadzirisa kutungamira munzvimbo dzakavhurika.
3. * * Sharp turn/stationary turn: * * Dhonza rumwe rutivi rwechidhiraivho chekufambisa kusvika pasi. Chekutanga, bvisa clutch kudivi iro, uye ramba uchiidhonza kuti uise bhureki kudivi iro pamwe chete. Inotyairwa nedivi remagetsi track, iyo braking side track inomiswa, uye muchina nekukasira kana munzvimbo inotenderera nepakati peiyo braking side track. Inokodzera kutendeuka kana kurongeka chaiko munzvimbo dzakamanikana.

4. * * Slope turning: * * Kutendeutsa pamateru kunoda kunyatso kudzora, uye mhinduro uye kutsvedzerera kwevharuvhu yekutungamirira kwakakosha kudzivirira kutsvedza kana kurasikirwa kwekudzora.
5. * * Kushanda kwakanyatsojeka: * * Mukushanda kwakanaka kwakadai sebulldozing uye kuenzana, kazhinji kacho kakona kadiki kekona kutendeuka kunodiwa, uye senitivity uye micro motion performance yevhavha inoshandura inobata zvakananga kunaka nekushanda kwekushanda.
6. * * Kupaka Kwakachengeteka: * * Mumamiriro ezvinhu ekukurumidzira, kukwevera mabhii maviri echidhiraivho kusvika pasi kunogona kukurumidza kubvisa maclutches kumativi ose uye kuisa mabhureki kumativi ose, zvichiita kuti bulldozer imire nokukurumidza (asi iyi haisi nzira yakajairika yokubhureki, sezvo bhureki guru rinowanzova negadziriro yakasiyana). Nheyo yekushanda kwekushanda: * * Kunzwa, kutsetseka, uye kurongeka kwekufambisa kunonyanya kuenderana nekugadzirwa uye chimiro chevharuvhu yekutungamirira.
*Kuvimbika kiyi: * * Steering system kutadza kunogona kukonzera bulldozer kutadza kutonga, izvo zvine njodzi. Iyo yekuisa chisimbiso, kupfeka kuramba, uye anti kusvibisa kugona kwevharuvhu yekutungamirira kwakakosha.
*Kushanda kwemaitiro: Yakapfava uye inoshanda kutungamira inoderedza kurasikirwa kwemagetsi uye kutambisa nguva.
*Kuneta kwemutyairi: Kurema, kukakamira, kana kusadaira kutyaira kunogona kuwedzera mutoro wekushanda kwemutyairi uye kuneta.
