Kulesi sihloko, uzofunda mayelana nenzwa yokuma ye-crankshaft enezintambo ezi-XNUMX kanye nomdwebo wayo wezintambo.

Uma wake wafaka noma uhlole inzwa ye-crankshaft enezintambo ezi-3 ngokwakho, cishe uyazi ukuthi yenziwa kanjani. Ukuhlonza izintambo ezi-3 ngeke kube umsebenzi olula. Ngakolunye uhlangothi, kufanele wazi ukuthi ungawaxhuma kuphi.

Inzwa ye-crankshaft iyisisetshenziswa sikagesi esibalulekile sokunquma isivinini senjini kanye nesikhathi sokubasa. Inzwa ye-crankshaft enezintambo ezi-3 iza nereferensi engu-5V noma engu-12V, isignali, namaphinikhodi aphansi. Lawa maphinikhodi amathathu axhuma ku-ECU yemoto.

"Qaphela: Ngokuya ngemodeli yemoto, umdwebo wokuxhuma wenzwa ye-crankshaft ungahluka."

Funda konke mayelana nezinzwa ze-crankshaft ezinezintambo ezi-3 kusukela kusihloko esingezansi.

Udinga ukwazi okuthile mayelana nenzwa ye-crankshaft

Imisebenzi esemqoka yenzwa ye-crankshaft ukunquma isivinini senjini kanye nesikhathi sokubasa. Le nzwa iyingxenye ebalulekile yazo zombili izinjini zikadizili nezikaphethiloli.

Qaphela. Kuye ngemodeli yemoto, umdwebo wezintambo zenzwa ye-crankshaft ungahluka.

Isibonelo, amanye amamodeli eza nenzwa yezintambo ezi-2 kanti amanye eza nenzwa enezintambo ezi-3. Kunoma yikuphi, indlela yokusebenza kanye nohlelo lokuxhuma ngeke luhluke kakhulu.

Ithiphu Esheshayo: Inzwa ye-crankshaft enezintambo ezi-3 ingahlukaniswa njengezinzwa ze-Hall effect. Kuhlanganisa uzibuthe, i-transistor, nezinto zensimbi ezifana ne-germanium.

Umdwebo wezintambo wenzwa ye-crankshaft enezintambo ezi-3

Njengoba ubona kumdwebo ongenhla, inzwa ye-crankshaft enezintambo ezi-3 iza nezintambo ezintathu.

Intambo yesithenjwa
ucingo lwesignali
umhlaba

Zontathu izintambo zixhunywe ku-ECU. Intambo eyodwa inikwa amandla yi-ECU. Le ntambo yaziwa ngokuthi i-5V (noma i-12V) yereferensi yentambo kagesi.

Intambo yesiginali isuka kunzwa iye ku-ECU. Futhi ekugcineni, intambo yaphansi iphuma ku-ECU, njengoba kwenza i-5V yereferensi yocingo.

I-voltage yereferensi kanye ne-voltage yesiginali

Ukuze uqonde kahle isekethe kagesi, udinga ukuqonda ireferensi nama-voltage esignali.

I-voltage eyireferensi i-voltage evela ku-ECU iye kunzwa. Ezimweni eziningi, le voltage yereferensi ingu-5 V, futhi ngezinye izikhathi ingaba ngu-12 V.

I-voltage yesignali yi-voltage enikezwa ku-ECU kusuka kunzwa.

Ithiphu Esheshayo: Ukuhlola imanuwali yomnikazi wemoto yakho kuyindlela engcono kakhulu yokunquma uhlobo lwenzwa ye-crankshaft. Isibonelo, imanuwali inemininingwane efana nohlobo lwenzwa kanye ne-voltage.

Ngabe inzwa yezintambo ezi-3 isebenza kanjani?

Uma into isondela kwinzwa, ukuguquguquka kazibuthe kwenzwa kuyashintsha, okuholela ku-voltage. Ekugcineni, i-transistor ikhulisa le voltage futhi iyithumele kukhompyutha esebhodini.

Umehluko phakathi kwezinzwa zezintambo ezingu-2 nezingu-3

Inzwa yezintambo ezi-3 inokuxhumana okuthathu ku-ECU. Inzwa enezintambo ezimbili inokuxhumana okubili kuphela. Inezintambo zesignali nezaphansi, kodwa ayikho intambo yesithenjwa yenzwa yokuma ye-crankshaft enezintambo ezi-XNUMX. Intambo yesignali ithumela i-voltage ku-ECU, futhi intambo yaphansi iqedela isekethe.

Izinhlobo ezintathu zezinzwa ze-crank

Kunezinhlobo ezintathu zezinzwa ze-crankshaft. Kulesi sigaba, ngizonikeza incazelo emfushane ngazo.

efundisayo

Ama-pickups asebenzisa imagnethi ukuze athathe amasiginali womsindo wenjini. Lezi zinhlobo zezinzwa zifakwe ku-cylinder block futhi uzokwazi ukubeka inzwa ye-crankshaft eduze kwe-crankshaft noma i-flywheel.

Izinzwa zohlobo lwe-inductive azidingi ireferensi kagesi; bakhiqiza i-voltage yabo. Ngakho-ke, inzwa enezintambo ezimbili iyinzwa yohlobo lwe-crankshaft inductive.

Inzwa yomphumela weHholo

Izinzwa zehholo zitholakala endaweni efanayo nezinzwa ze-inductive. Nokho, lezi zinzwa zidinga amandla angaphandle ukuze zisebenze. Ngakho-ke, bahlinzekwa ngocingo lwereferensi ye-voltage. Njengoba ngishilo, le voltage yereferensi ingaba yi-5V noma i-12V. Lezi zinzwa zakha isignali yedijithali kusukela kusignali ye-AC eyamukelwe.

Ithiphu Esheshayo: Izinzwa ze-crankshaft ezinezintambo ezintathu ziwuhlobo lweHholo.

Izinzwa eziphumayo ze-AC

Izinzwa ze-AC zihluke kancane kwezinye. Esikhundleni sokuthumela amasignali edijithali njengezinzwa ze-Hall, izinzwa ezinokuphuma kwe-AC zithumela isignali kagesi ye-AC. Lezi zinhlobo zezinzwa zivame ukusetshenziswa ezinjinini ze-Vauxhall EVOTEC.

Imibuzo evame ukubuzwa

Zingaki izintambo ezixhunywe kwinzwa yendawo ye-crankshaft?

Inani lezintambo lingahluka kuye ngemodeli yemoto. Isibonelo, ezinye izinhlobo zezimoto ziza nezinzwa ezinezintambo ezi-2 kanti ezinye ziza nezinzwa ezinezintambo ezi-3.

Njengoba uqonda, inzwa enezintambo ezimbili inezintambo ezimbili, kanti inzwa enezintambo ezintathu inezintambo ezintathu.

Kungani izinzwa ze-crankshaft ezinezintambo ezi-3 zidinga ireferensi kagesi?

Izinzwa ze-crankshaft ezinezintambo ezintathu zidinga i-voltage evela emthonjeni wangaphandle ukuze zenze i-voltage yesiginali. Ngakho-ke, lezi zinzwa ziza namatheminali amathathu futhi eyodwa yazo imele i-voltage yereferensi. Amanye amatheminali amabili awokuxhumanisa isignali kanye nomhlabathi.

Nokho, izinzwa ze-crankshaft ezinezintambo ezi-2 azidingi ireferensi kagesi. Bakhiqiza i-voltage yabo futhi bayisebenzisele ukudala i-voltage yesiginali.

Ingabe i-voltage eyireferensi i-5V yenzwa ngayinye ye-crankshaft?

Cha, i-voltage yereferensi ngeke ibe ngu-5V njalo. Ezinye izinzwa ze-crankshaft ziza nereferensi engu-12V. Kodwa khumbula, ireferensi ye-5V iyona evame kakhulu.

Kungani ireferensi ye-5V ijwayelekile embonini yezimoto?

Noma amabhethri emoto ehlinzeka phakathi kuka-12.3V no-12.6V, izinzwa zisebenzisa i-5V kuphela njenge-voltage yazo eyireferensi.

Kungani izinzwa zingakwazi ukusebenzisa wonke ama-12V?

Hhayi-ke, kukhohlisa kancane. Isibonelo, uma uvula imoto, i-alternator iyakhahlela bese ikhipha i-voltage eyengeziwe ebangeni elingu-12.3 kuya ku-12.6 volts.

Kodwa i-voltage ephuma ku-generator ayilindeleki kakhulu. Ikwazi ukucisha i-12V futhi kwesinye isikhathi ingakwazi ukucima i-11.5V. Ngakho ukwenza izinzwa ze-crankshaft eziyi-12V kuyingozi. Esikhundleni salokho, abakhiqizi bakhiqiza izinzwa ze-5V futhi bazinzise i-voltage ngesilawuli se-voltage.

Ungakwazi yini ukuhlola inzwa yendawo ye-crankshaft?

Yebo, ungayihlola. Ungasebenzisa i-multimeter yedijithali kulokhu. Hlola ukumelana kwenzwa futhi uyiqhathanise nevelu yokumelana nokulinganisa. Uma uthola umehluko omkhulu phakathi kwalawa manani amabili, inzwa ye-crankshaft ayisebenzi kahle.
