Idizayini kanye nenqubo yokusebenza kwebhuleki yokupaka ye-electromechanical (EPB)
Okuqukethwe
Ingxenye ebalulekile yanoma iyiphi imoto ibhuleki yokupaka, ekhiya imoto endaweni ngesikhathi sokupaka futhi iyivimbele ekugingqikeni emuva noma phambili ingahlosile. Izimoto zesimanje ziya ngokuya zihlonyelwa uhlobo lwe-elektrikhi lokubhaka lokupaka, lapho i-elektroniki ithatha indawo "yebhuleki lesandla" elijwayelekile. Isifinyezo se-Electromechanical Parking Brake “EPB” sisho i-Electromechanical Parking Brake. Ake sibheke imisebenzi esemqoka ye-EPB nokuthi yehluke kanjani kubhuleki wakudala wokupaka. Ake sihlaziye izinto zedivayisi kanye nomgomo wokusebenza kwayo.
Imisebenzi ye-EPB
Imisebenzi esemqoka ye-EPB yile:
- ukugcina imoto isendaweni lapho ipakiwe;
- ukubopha amabhuleki okuphuthumayo uma kwenzeka ukwehluleka kohlelo lwamabhuleki esevisi;
- ukuvimba imoto ukuthi ingahlehli emuva uma iqala ekukhuphukeni intaba.
Idivayisi ye-EPB
Ibhuleki lesandla elenziwa nge-electromechanical lifakwe emasondweni angemuva emotweni. Ngokwesakhiwo, iqukethe izinto ezilandelayo:
- ukubopha indlela;
- idrayivu yunithi;
- uhlelo lokulawula i-elekthronikhi.
Indlela yokubopha amabhuleki imelwe ngamabhuleki ejwayelekile emoto. Izinguquko zokuklama zenziwa kuphela kumasilinda asebenzayo. I-actuator yokupaka ibhagi ifakwe kwi-caliper brake.
Idrayivu kagesi yokupaka ibhuleki iqukethe izingxenye ezilandelayo, ezisendlini eyodwa:
- motor kagesi;
- Ukuqothula;
- i-reductorar yeplanethi;
- isikulufa drive.
Imoto kagesi ishayela u-gearbox wamaplanethi nge-drive drive. Okokugcina, ngokunciphisa izinga lomsindo nesisindo sedrayivu, kuthinta ukuhamba kwe-screw drive. Idrayivu yona ibhekele ukunyakaza kokuhumusha kwepiston yamabhuleki.
Iyunithi yokulawulwa kwe-elekthronikhi iqukethe:
- izinzwa zokufaka;
- iyunithi yokulawula;
- izindlela zokuphatha.
Izimpawu zokufaka zifika kwiyunithi yokulawula kusuka okungenani ezintweni ezintathu: kusuka kunkinobho yokwenza kusebenze ibhuleki lesandla (etholakala ku-centre console yemoto), kusuka enzwa ye-slope (ehlanganiswe neyunithi yokulawula uqobo) naku-clutch pedal sensor (etholakala i-clutch actuator), erekhoda isikhundla nesivinini sokukhishwa kwe-pedal clutch.
Iyunithi yokulawula isebenza kuma-actuator ngokusebenzisa amasiginali wezinzwa (njenge-drive motor, isibonelo). Ngakho-ke, uphiko lokulawula luxhumana ngqo nokuphathwa kwenjini nezinhlelo zokuqina kokuqina.
Isebenza kanjani i-EPB
Umgomo wokusebenza kwebhuleki yokupaka ye-electromechanical ujikeleza: iyavula futhi icime.
I-EPB iyasebenza ngokusebenzisa inkinobho esethilini eliphakathi nendawo egumbini labagibeli. Imoto kagesi, esebenzisa u-gearbox ne-screw drive, idonsela ama-brake pads kwi-disc brake. Kulokhu, lesi sakamuva siqinile.
Futhi ibhuleki yokupaka icishiwe ngesikhathi kuqala imoto. Lesi senzo senzeka ngokuzenzakalela. Futhi, ibhuleki lesandla elenziwe ngogesi lingacishwa ngokucindezela inkinobho ngenkathi inyathela lamabhuleki selivele licindezelwe.
Ngenqubo yokuyekisa i-EPB, uphiko lokulawula luhlaziya imingcele enjengebanga lethambeka, isikhundla se-accelerator pedal, isikhundla nesivinini sokukhipha i-clutch pedal. Lokhu kwenza kube lula ukucisha i-EPB ngesikhathi esifanele, kufaka phakathi ukucisha okulibaziseke ngesikhathi. Lokhu kuvimbela imoto ukuthi iginqike emuva lapho iqala ukuthambekela.
Izimoto eziningi ezifakwe ama-EPB zinenkinobho ye-Auto Hold eduze kwenkinobho yebhuleki lesandla. Lokhu kulula kakhulu ezimotweni ezinokudluliswa okuzenzakalelayo. Lo msebenzi uhambisana kakhulu neziminyaminya zasemadolobheni ngokuma kaningi nokuqala. Lapho umshayeli ecindezela inkinobho "Auto Hold", asikho isidingo sokubamba phansi ibhuleki ngemuva kokumisa imoto.
Lapho imile isikhathi eside, i-EPB ivuleka ngokuzenzakalela. Ibhuleki lesandla lokupaka likagesi nalo lizovuleka ngokuzenzekelayo uma umshayeli ecisha ugesi, evula umnyango noma eqaqa ibhande lesihlalo.
Izinzuzo nokubi kwe-EPB Uma kuqhathaniswa ne-Classic Parking Brake
Ukucacelwa, ubuhle nobubi be-EPB uma kuqhathaniswa nebhuleki lesandla elijwayelekile kuvezwa ngendlela yetafula:
| Izinzuzo ze-EPB | Okubi kwe-EPB |
|---|---|
| 1. Inkinobho ehlangene esikhundleni sesigwedlo esinamandla | 1. Imishini yokupaka ibhuleki ikuvumela ukuthi ulungise ibhuleki, engatholakali ku-EPB |
| 2. Ngesikhathi sokusebenza kwe-EPB, asikho isidingo sokuyilungisa | 2. Ngebhethri ekhishwe ngokuphelele, akunakwenzeka "ukukhipha kubhuleki lesandla" |
| 3. Ukuvalwa okuzenzakalelayo kwe-EPB lapho uqala imoto | 3. Izindleko eziphakeme |
| 4. Akukho ukubuyiselwa emuva kwemoto ekukhuphukeni |
Izici zokugcinwa nokusebenza kwezimoto ezine-EPB
Ukuhlola ukusebenza kwe-EPB, imoto kufanele ifakwe kwi-brake tester futhi ibhuleke nge-brake yokupaka. Kulokhu, isheke kufanele lenziwe njalo.
Amapayipi amabhuleki angashintshwa kuphela lapho kukhishwa ibhuleki yokupaka. Inqubo yokufaka esikhundleni yenzeka kusetshenziswa imishini yokuxilonga. Amapayipi asethwa ngokuzenzakalela endaweni oyifunayo, ebekwe kwimemori yeyunithi yokulawula.
Ungayishiyi imoto ibhuleki yokupaka isikhathi eside. Uma ipakiwe isikhathi eside, ibhethri liyakwazi ukukhishwa, ngenxa yalokho imoto engenakususwa kubhuleki yokupaka.
Ngaphambi kokwenza umsebenzi wobuchwepheshe, kuyadingeka ukushintshela i-elektroniki yemoto kwimodi yesevisi. Ngaphandle kwalokho, ibhuleki lesandla likagesi lingavuleka ngokuzenzekelayo ngesikhathi sokusevisa noma sokulungisa imoto. Lokhu nakho kungalimaza imoto.
isiphetho
Ibhuleki yokupaka ye-electromechanical ikhulula umshayeli enkingeni yokukhohlwa ukususa imoto kubhuleki yokupaka. Ngenxa ye-EPB, le nqubo yenzeka ngokuzenzakalela lapho imoto iqala ukuhamba. Ngaphezu kwalokho, yenza kube lula ukuqala ukukhuphuka kwemoto futhi yenze lula kakhulu impilo yabashayeli ezimotweni zomgwaqo.
