Izidingo eziyisisekelo ze-Rexroth A4VTG090
I-A4VTG090 iyinhlobo ye-umpompi we-axial-piston we-swashplate-type, ongu-variable-displacement ku-ukushayela kwe-hydrostatic okuvaliweyo. Inezici ezithile pressure ejwayelekile engu-400 bar no ingcindezi ephezulu engu-450 bar, enokuhamba kwejiyomethri ka 90 cm³/rev. Iziqondiso ezijwayelekile zokushesha okuphezulu zingu ≈3050 rpm ku-Vg max no-≈500 rpm okuncane; ku-n nom no Vg max, ukuhamba okukhuluma cishe ku-275 L/min. Izicelo ezivamile zifaka imikhiqizo yokuxuba ukhonkolo ephathekayo nezinye imishini esindayo esheshayo. Imisebenzi eyinhloko efakiwe ifaka amavavavu amabili okukhulula ingcindezi ephezulu (okwenza njengo-ama-valve okwandisa) kanye ne-umpompi wokwandisa ohlanganisiwe ukuze ukudla nok pressure yokulawula. Uchungechunge luhlonziwe Uchungechunge 33 ngezilinganiso NG71/90.
Ukuchazwa kwekhodi yemodeli yezinhlobo ezibalwe
Idivayisi yokulawula (izimpawu zokuqala ezi-3 ngemuva kosayizi):
EP3 = Ukulawula kwe-electro-proportional, 12 V DC i-coil, ukubuyisela kwe-spring ngokusebenza okuphuthumayo.
EP4 = Ukulawula kwe-electro-proportional, 24 V DC coil, ukubuyiselwa kwesiphethu ngokusebenza kwesimo esiphuthumayo.
HW1 = Ukulawula kwe-Hydraulic (mechanical servo); amaningi ama-catalog entries asebenzisa ifomu elifushane HW kulolu familia.
Izithako nezinketho:
P0 = Inguqulo ejwayelekile ngaphandle kokuxhumana kwe-elekthronikhi okwengeziwe ngaphandle kokulawula; incazelo eqondile ichazwa yi-ikhodi yohlobo ephelele kanye nephepha ledatha.
PT = Ikhombisa i-umpompi enesixhumi/adapter; emikhiqizweni eminingi lezi zixhunywe ne-AZ‑P‑F‑12 (i-interface/plug kit enama-12 pins). Uma i-interface ingadingeki, P0 ivamise ukusetshenziswa.
Umgomo wekhodi ye-typ uchaza Uhlaka (33), flange/shaft/through‑drive, izikhala/design, futhi uhlobo/ukuphuma (isb., /33MRNC4C92F0000AS‑0). Ngaso sonke isikhathi order usebenzisa i-ikhodi ye-type ephelele futhi uqinisekise ngokumelene ne-iphaneli yegama.
Ukuqhathaniswa okusheshayo kwamakhodi akhankanyiweyo
Ikhodi | Umndeni wokulawula | I-voltage ye-coil | Interface/izincazelo | Isibonelo se-P/N ephelele |
|---|---|---|---|---|
A4VTG090EP3P0 | EP (electro‑proportional) | 12 V DC | Inguqulo ejwayelekile (ayikho i-I/O eyengeziwe ekhankanyiweyo) | A4VTG090EP3P0/33MRNC4C92F0000AS‑0 |
A4VTG090EP3PT | EP (electro‑proportional) | 12 V DC | Iphampu enengxoxo yokulawula; ivame ukuhlinzekwa nge-AZ‑P‑F‑12 | A4VTG090EP3PT/33+AZ‑P‑F‑12 |
A4VTG090EP4P0 | EP (electro‑proportional) | 24 V DC | Inguqulo ejwayelekile | A4VTG090EP4P0/33MRNC4V92F0000AS‑0 |
A4VTG090EP4PT | EP (electro‑proportional) | 24 V DC | Umpompi onesixhumi sokulawula; uvame ukuhlinzekwa nge-AZ‑P‑F‑12 | (Isakhiwo se-P/N esifanayo ne-EP3PT enokulawula kwe-EP4) |
A4VTG090HW100 | HW (i-hydraulic servo) | — | Ukulawulwa kwe-mechanical/hydraulic; izinhlobo eziningi zisebenzisa isithasiselo 100 ku-ikhodi yohlobo | A4VTG090HW100/33MRNC4C92F0000AS‑0 |
A4VTG090HW10T | HW (i-hydraulic servo) | — | Uhlobo lwe-HW100; incazelo ethile ichazwe ngesisekelo esiphelele | (Izinhlobo ze-HW10T zibhaliwe kumakhalekhukhwini abahlinzeki) |
Zonke izikhodi ezibalwe ziyiUchungechunge 33, usayizi NG90 amapompo e-closed‑circuit; izinhlobo ze-EP zihluka nge-umbane we-coil (12 V vs 24 V), no P0 vs PT ibonisa ukuthi ingabe isixhumi sokulawula ifakiwe. Izinhlobo ze-HW zingu ukulawulwa kwe-hydraulic enezinketho eziningi zokuphuma zokufaka/ukudlula nokuqamba.
Indlela yokukhetha phakathi kwe-EP3, EP4, kanye ne-HW
Uma imishini isebenzisa 12 V DC izixhumi zokulawula, khetha EP3; ukuze 24 V DC, khetha EP4. Khetha HW uma i-i-hydraulic/mechanical servo umjikelezo wokulawula uthandwa.
Uma i-ihlanganisi/ikhithi yeplagi ehlukile kudingeka ku-harness/ECU yakho, sebenzisa i-PT isithasiselo (ngokuvamile ne-AZ‑P‑F‑12); uma ukulawula kuhlanganisiwe noma i-interface ayidingeki, sebenzisa P0.
Hlanganisa ne-ikhodi ye-typ e komplethi (kuhlanganisa Uchungechunge, flange/shaft, amaphuzu, kanye nesuffix) ku-uhlu lwezingxenye/ibhodi lesikhumbuzo ukuze kuqinisekiswe ukuhambisana kokulawula nokulungiswa okufanele.
Izicelo ezijwayelekile nezincwadi zokorder
Lezi zimpompi zisetshenziswa kabanzi ku-izixhumi ze-concrete ezihambayo nezinye ukwakhiwa/ukuphuma emgwaqweni imishini edinga ubukhulu bamandla aphezulu no circuit evaliwe ukulawula.
Ukutholakala: okuningi EP3/EP4/PT futhi HW100 izinhlobo zigcinwa ngabathengisi beRexroth; izibonelo zifaka A4VTG090EP3P0/33MRNC4C92F0000AS‑0, A4VTG090EP3PT/33+AZ‑P‑F‑12, no-A4VTG090HW100/33MRNC4C92F0000AS‑0. Qinisekisa njalo ikhodi ye-type ephelele, ukushintsha kokulawula, kanye no ikiti yokuxhumana ngaphambi kokuthi u-oda.
