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>Ensengekera enkulu, ng’emikutu gy’amafuta egy’amaanyi gikolebwa munda.

*Control Valve Core: Ekitundu kya core, ebiseera ebisinga vvaalu ya slide oba vvaalu ekyukakyuka. Ekifo kyayo kifugibwa ekiwato kya siteeringi nga kiyita mu kuyungibwa kw’ebyuma oba woyiro ow’amazzi (pilot hydraulic oil), nga kizuula butereevu obulagirizi bw’ekisenge kya woyiro.
*Overflow valve/safety valve: * * Ekoma ku puleesa esinga obunene ey'enkola era ekuuma ebitundu by'amazzi.
** * Check valve: * * Eziyiza amafuta okudda emabega n’okukuuma puleesa.
** * Ekinnya kya throttle/damping Hole: * * Okufuga omuwendo gw’amafuta agakulukuta okukakasa ekikolwa kya siteeringi ekiweweevu n’okukendeeza ku kukwata ku sseppulingi ya reset. : * * Kakasa nti omusingi gwa vvaalu gudda mu kifo ekitaliimu (Straight Ahead position) nga ekiwato ekifuga kifulumizibwa: * * Yunga omukutu oguyingira (okuva mu ppampu ya siteeringi), port ekomawo (Ttanka ekomawo), emiryango gya woyiro ku kkono ne ddyo siteeringi za siteeringi, ne ports za woyiro ku ssiringi za left ne ddyo eza buleeki (oba enkola y’okuyunga ku nkola y’okuyunga) obuzito bwa ssiringi z’amasannyalaze mu kipimo kya lectly mu 1. Enkola enzibu, ekiwato ekifuga kiyinza okusooka okufuga low-okunyigiriza pilot valve, olwo omusingi gwa valve omukulu ne guvugibwa amafuta aga pilot. Enkola ekola: Neutral (straight): Ekiwato ekifuga kiri mu kifo kya wakati, ate omusingi gwa vvaalu guli mu mbeera ya neutral. Amafuta ga puleesa tegakulukuta ku ssiringi ya kalaagi (clutch esigala nga yeegatta), era tekulukuta ku ssiringi ya buleeki (okufuluma kwa buleeki). Amafuta agava mu ppampu ya woyiro gayinza okuddizibwa butereevu mu ttanka oba okusaasaanyizibwa okuyita mu mukutu gw’okutikkula wansi-okunyigiriza (okusinziira ku dizayini). Siteeringi (PULL SROD): Omukozi bw’asika oludda olumu olw’omuggo gwa siteeringi, omusingi gwa vvaalu gutambula, n’aggulawo ekiyungo kya woyiro n’asobozesa amafuta ga puleesa okuyingira mu ssiringi y’okufulumya eya siteeringi ku ludda olwo (oludda olwa kkono), okusika pisitoni okuggyamu kalati n’okusala amaanyi g’olutindo olwa kkono. At the same time, this action may be linked to open another oil circuit (or through a mechanical linkage mechanism), allowing pressure oil to enter the brake cylinder on that side (left side), apply braking (usually effective when the control lever is pulled to the second half, achieving a quick turn), maintain power on the right track, push the machine to turn left, reset (release the lever): release the control lever, the reset spring pushes the valve core back to the center position, cuts Off the pressure oil to the separation cylinder, era amafuta agali mu ssiringi ey’okwawula gafuluma okudda mu ttanka y’amafuta wansi w’ekikolwa kya clutch reset spring. Clutch eddamu okuyungibwa, era woyiro wa puleesa ku ssiringi ya buleeki asalibwako (oba omukutu gwa woyiro ogudda guggulwawo). Bbuleeki efuluma wansi w’ekikolwa kya reset spring.

Okusaba

Ekibiina kya steering valve ekya bulooka kye kitundu ekikulu ekiteetaagisa ennyo ekya bulooka erondooleddwa, era okukozesebwa kwayo kweyolekera butereevu mu mirimu egy’enjawulo egya siteeringi egya bulooka:

.
. Oluguudo lw’oku ludda lw’amaanyi lusika olugendo lw’oludda olw’okwawula mu maaso okusobola okutuuka ku kukyuka okugonvu. Esaanira okutereeza obulagirizi mu bifo ebiggule.
3. * * SHARP turn/stationary turn: * * Sika oludda olumu olwa lever ya siteeringi okutuuka wansi. Ekisooka, ggyamu kalati ku ludda olwo, era weeyongere okugisika okusiiga buleeki ku ludda olwo ng’okwataganye. Nga evugirwa olutindo lw’amaanyi olw’oku ludda lw’amaanyi, olutindo lw’oku ludda olukuba buleeki luyimirira, era ekyuma mu bwangu oba mu kifo kyakyo ne kikyuka wakati mu makkati g’olutindo lw’oku ludda olw’okusimbula. Esaanira okukyuka oba okukwatagana okutuufu mu bifo ebifunda.

. Omusingi gw’omulimu gw’okukola: * * Obuwulize, okugonvuwa, n’obutuufu bwa siteeringi okusinga bisinziira ku dizayini n’embeera ya vvaalu ya siteeringi.
*Ekisumuluzo ky'obwesigwa: * * Okulemererwa kw'enkola ya siteeringi kuyinza okuvaako bulooka okubulwa obuyinza, ekintu eky'obulabe ennyo. Obusobozi bw’okusiba, okwambala, n’okuziyiza obucaafu bwa vvaalu ya siteeringi bikulu nnyo.
*Okukosa obulungi: Siteeringi ekendeeza ku kufiirwa amasannyalaze n’obudde.
*Okukoowa kwa ddereeva: Siteeringi enzito, ekwatiddwa, oba etaddamu esobola okwongera ku buzito bwa ddereeva bw’ekola n’obukoowu.
