Hom thiab installation txoj kev ntawm hydraulic retarders

● Retarder keeb kwm

Tam sim no muaj ob yam tseem ceeb ntawm retarders rau tsheb, ib qho yog eddy tam sim no retarder thiab lwm yam yog hydrodynamic retarder uas peb feem ntau pom ntawm cov tsheb thauj khoom.

Tus thawj eddy tam sim no retarder, yug nyob rau hauv Fabkis nyob rau hauv 1936, muaj keeb kwm ntawm ntau tshaj 80 xyoo.

Eddy tam sim no retarder txoj haujlwm ua haujlwm:

Eddy tam sim no retarder, siv lub hauv paus ntsiab lus ntawm electromagnetism los hloov lub kinetic zog ntawm lub tsheb tsav mus rau hauv lub tshav kub zog yuav tsum tau emissions, thiaj li mus paub deceleration thiab braking.

Qhov zoo ntawm eddy tam sim no retarder yog cov lus teb ceev ceev, tus nqi qis, thiab kev teeb tsa yooj yim. Tau kawg, kuj tseem muaj qhov tsis zoo, xws li qhov hnyav hnyav, me me braking torque, thiab kev ua haujlwm siab. Tam sim no, qhov kev faib ua feem ntawm eddy tam sim no retarder siv rau cov tsheb thauj khoom yog twb tsawg heev, thaum nws yog siv ntau nyob rau hauv tsheb npav.

Xyoo 1961, Lub Tebchaws Yelemes Voith tau tsim cov hydraulic retarder. Thaum xub thawj, hydraulic retarders tau siv rau hauv tsheb ciav hlau rau kev txo qis ua ntej siv rau cov tsheb thauj khoom tom qab.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm hydraulic retarder yog raws li nram no:

Lub hydraulic retarder compresses cua mus rau hauv cov roj cia tank los ntawm ib tug proportional valve, thiab cov roj yog pressurized rau hauv lub retarder los ntawm cov roj Circuit Court pib nws cov hauj lwm. Lub rotor tsav cov kev sib hloov ntawm cov roj, thiab cov roj txav mus rau hauv cov kev taw qhia ntawm cov hniav, ntuav mus rau lub stator, yog li tsim ib tug kuj torque tiv thaiv lub rotor, impeding lub tsheb txoj kev sib hloov thiab ua tiav cov nyhuv deceleration.

Piv nrog rau cov eddy tam sim no retarder, hydraulic retarders muaj qhov pom tseeb zoo, nrog rau lub teeb yuag, me me, siab dua braking torque, thiab kho yooj yim dua. Txawm li cas los xij, lub ntsiab drawback ntawm hydraulic retarders yog lawv cov nqi siab dua.

Tam sim no muaj peb yam tseem ceeb ntawm hydrodynamic retarders, raws li cov txheej txheem installation, uas yog: series, parallel thiab ywj siab.

Series Installation hydraulic retarder

Lub series installation retarder yog ntsia nyob rau hauv lub rear kawg ntawm kis tau tus mob, qhov twg cov hydraulic retarder yog kev cob cog rua nyob rau hauv series nrog lub gearbox. Lub hwj chim yog kis los ntawm lub retarder mus rau lub rear qag.

Parallel installation hydraulic retarder

Parallel installation hydraulic retarder mounted nyob rau sab ntawm cov kis tau tus mob (feem ntau nyob rau sab laug), hydraulic retarder thiab kis tau tus mob rau lub parallel qauv, lub hwj chim tsis tas yuav kis tau los ntawm lub retarder yuav kis tau mus rau lub rear qag.

ywj siab installation hydraulic retarder

Nyob rau hauv lub ywj siab installation hydraulic retarder tsis tas yuav tsum tau ntsia rau ntawm lub gearbox. Nws yog ntsia nruab nrab ntawm lub gearbox thiab lub rear qag siv ib tug cais bracket. Qhov zoo ntawm qhov tsim no yog nws qhov dav adaptability rau ntau lub tsheb qauv.
