195-40-00900stering Lub VALVE ANTY (B)

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>Cov qauv tseem ceeb, nrog cov roj sib txawv ntawm cov roj txuas sab hauv.

* Tswj valve core: cov khoom sib xyaw ua ke, feem ntau yog ib qho chaw swb lossis lub valve. Nws txoj hauj lwm yog tswj hwm los ntawm kauj qib dhau los ntawm cov neeg siv tshuab lossis sim cov roj hauv cov roj hauv lub voj voog.
* Overflow valve / kev nyab xeeb valve: * * txwv qhov siab tshaj plaws ntawm cov kab ke thiab tiv thaiv kev tiv thaiv hydraulic.
** * Tshawb xyuas Valve: * Tiv thaiv cov roj backflow thiab tswj hwm lub siab.
** * throttle qhov / damping qhov: * tswj cov roj flow tus nqi kom ntseeg tau cov kauj ruam du thiab txo qhov cuam tshuam ntawm lub caij nplooj ntoo hlav rov qab. : * Nco ntsoov tias lub valve lub chaw xa rov qab rau qhov chaw nruab nrab (los ntawm lub tshuab hluav taws xob ua ke (lossis cov roj txuas rau sab laug) Cov tshuab, tus tswj tau tswj tau ua ntej tswj qhov qis- siab} lub zog loj corot yog tsav los ntawm kev tsav roj loj. Ua haujlwm ua haujlwm: nruab nrab (ncaj): txoj kev tswj hwm yog nyob rau hauv nruab nrab txoj hauj lwm, thiab lub valve core nyob hauv nruab nrab txoj hauj lwm. Cov roj siab tsis ntws mus rau tus clutch lub tog raj kheej (clutch nyob), tsis yog nws ntws mus rau lub tog raj kheej nres (nres tso). Cov roj los ntawm cov roj twj yuav rov qab rau hauv lub tank lossis ncig ua si los ntawm qhov qis {6} pav unloading channel (nyob ntawm tus tsim). Steering (rub tus pas nrig): Thaum tus neeg teb xov tooj ib sab ntawm lub kauj sab nraud, thawb lub piston kom disengage lub clutch thiab txiav tawm lub zog ntawm txoj kev sab laug. Nyob rau tib lub sijhawm, qhov kev txiav txim no tuaj yeem txuas rau lwm cov roj hluav taws xob (khawm lub tshuab tswj kev nce qib thib ob), siv lub zog tig mus rau lub valve txoj haujlwm rov qab mus rau qhov chaw nruab nrab, txiav tawm Lub siab roj rau kev sib cais lub tog raj kheej, thiab cov roj hauv kev sib cais lub tog raj kheej yog tso tawm rov qab rau cov roj tank nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoo hlav rov qab. Tus clutch yog rov ua dua tshiab, thiab cov roj siab rau lub tog raj kheej nres yog txiav tawm (lossis cov roj channel xa rov qab). Tus nres tau tso tawm hauv qab kev ua ntawm lub caij nplooj ntoo hlav rov pib dua.

Daim ntawv thov

Lub kauj ruam sib dhos ntawm lub tsheb nrau av yog qhov tseem ceeb ntawm tus tseem ceeb ntawm cov tsheb thauj khoom ntawm cov kauj ruam ntawm cov tsheb nrau av:

1. * *
2. * * Lub voj voos hloov pauv (lub vojvoog loj ( Lub zog sab taug kev thawb cov kab sib cais ua kom tiav rau pem hauv ntej kom ua tiav txoj siav du. Haum rau kev kho cov kev taw qhia hauv qhov chaw qhib.
3. Firstly, disengage lub clutch ntawm sab ntawd, thiab txuas ntxiv mus rub nws los thov tus brake rau ntawm sab ntawd ua ke. Tsav los ntawm lub zog tog sab, lub braking sab ciav hlau yog nres, thiab lub tshuab nrawm lossis hauv qhov chaw hloov ib puag ncig ntawm lub braking sab. Haum rau kev tig lossis kho cov kev vam meej hauv qhov chaw nqaim.

4. * * Txoj kab nqes hav: * * Tig rau txoj kab nqes yuav tsum muaj ntau txoj kev tswj, thiab cov lus teb thiab du ntawm cov kauj vab yog qhov tseem ceeb los tiv thaiv kom tsis txhob tswj.
5.
6. * * Cov chaw nres tsheb nyab xeeb: * * Hauv ob tog ntawm ob tog tuaj yeem nres nrawm dua, vim tias qhov chaw nres tsheb tau sai sai, raws li lub qhov muag tseem ceeb feem ntau muaj lwm qhov system). Cov tub ntxhais ntawm kev ua haujlwm ua haujlwm: * * qhov rhiab, thiab qhov tseeb ntawm tus qauv tsim nyog nyob ntawm tus tsim thiab cov xwm txheej ntawm lub kauj valve.
* Kev ntseeg siab yuam: * * Steering System Ua tsis tiav tuaj yeem ua rau lub tsheb nrau av kom plam kev tswj hwm, uas yog qhov txaus ntshai heev. Kev sealing, hnav tsis kam, thiab anti muaj kuab paug muaj peev xwm ntawm cov kauj valve yog qhov tseem ceeb.
* Kev cuam tshuam ua tau zoo: du thiab siv hluav taws xob txo lub zog poob thiab lub sijhawm pov tseg.
* Tsav tsheb nkees nkees: hnyav, daig, lossis tus kauj ruam tuaj yeem ua rau tus tsav tsheb ua haujlwm lub nra thiab qaug zog.
