Emergency braking usoro

26.05.2022 /

Otu n'ime ihe dị mkpa na-egbochi ihe mberede ma ọ bụ belata nsonaazụ ya bụ usoro braking mberede. Ọ dị mkpa maka ịrụ ọrụ nke ọma nke usoro braking na ọnọdụ dị oke egwu: na nkezi, nkwụsị braking nke ụgbọ ala na-ebelata site na pasent iri abụọ. N’ụzọ BAS ma ọ bụ onye enyemaka breeki nwere ike ịtụgharị dị ka “onye enyemaka breeki”. The inyeaka mberede braking usoro (na-adabere n'ụdị) ma na-enyere ndị ọkwọ ụgbọala na mberede braking (site na "ịpị" breeki pedal), ma ọ bụ na-akpaghị aka brek ụgbọ ala na-enweghị onye na-akwọ òkè ruo mgbe ọ na-abịa na njedebe zuru ezu. N'isiokwu ahụ, anyị ga-atụle ngwaọrụ, ụkpụrụ nke ọrụ na ụdị nke usoro abụọ a.

Di iche-iche nke sistemu nkpuchi mberede nke enyemaka

E nwere ihe abụọ dị iche iche nke ihe enyemaka nyere usoro braking:

  • enyemaka braking mberede;
  • akpaka mberede braking.

Nke mbụ na - emepụta nrụgide braking kachasị elu nke na - esite na onye ọkwọ ụgbọala na - pịa pedal brek. N'ezie, ọ "brek" maka ọkwọ ụgbọala. Nke abụọ na-arụ otu ọrụ ahụ, mana na-enweghị òkè nke onye ọkwọ ụgbọ ala. Usoro a bụ akpaka.

Emergency braking enyemaka usoro

Dabere na ụkpụrụ nke ịmepụta oke nrụgide braking, a na-ekewa ụdị usoro a n'ime pneumatic na hydraulic.

Pneumatic Mberede breeki Enyemaka

Sistemụ ikuku na-eme ka arụmọrụ kachasị elu nke ihe nkwalite breeki agụụ. Ọ mejupụtara ihe ndị a:

  1. ihe mmetụta nke dị n'ime ampilifaya agụụ na-atụ ma na-atụ ọsọ nke ngagharị nke mkpanaka ampilifaya ahụ;
  2. electromagnetic mkpanaka mbanye;
  3. kọmputa njikwa unit (ECU).

A na-arụkarị ụdị pneumatic na ụgbọ ala ndị nwere usoro mgbochi mkpọchi mkpọchi (ABS).

Principlekpụrụ nke usoro a dabere na ịmara ọdịdị nke braking mberede site na ọsọ nke onye ọkwọ ụgbọ ala na-agba ọsọ ụkwụ. Edere ọsọ ọsọ a site na ihe mmetụta, nke na-ebunye nsonaazụ ya na sistemụ njikwa kọmputa. Ọ bụrụ na mgbaàmà ahụ karịrị uru ahaziri, ECU na-eme ka mkpanaka actoator solenoid rụọ ọrụ. Agụụ breeki booster presses breeki pedal megide nkwụsị. Ọbụna tupu ABS amalite, a na-eme braking mberede.

Pneumatic mberede braking enyemaka usoro gụnyere:

  • BA (Breeki Enyemaka);
  • BAS (Usoro Nkwado Brake);
  • EBA (Emergency Brake Assist) - awụnyere na ụgbọ ala Volvo, Toyota, Mercedes, BMW;
  • AFU - maka Citroen, Renault, Peugeot.

Hydraulic Mberede breeki Enyemaka

Thedị hydraulic nke "ezumike nyere aka" na-emepụta nrụgide mmiri kachasị na sistemụ breeki n'ihi ihe nke ESC (Njikwa ụgbọ ala nkwụsị).

Structurally, usoro a gụnyere:

  1. breeki mgbali mmetụta;
  2. igwe na-agba ọsọ ọsọ ma ọ bụ ihe mmetụta agụụ na ampilifaya agụụ;
  3. breeki ọkụ mgba ọkụ;
  4. ECU.

Usoro ahụ nwekwara ọtụtụ ụdị:

  • HBA (Hydraulic Braking Assistance) arụnyere na Volkswagen, Audi;
  • HBB (Hydraulic Brake Booster) tinyekwara na Audi na Volkswagen;
  • SBC (Sensotronic Brake Control) - Ezubere maka Mercedes;
  • DBC (Dynamic Brake Control) - tinye na BMW;
  • BA Plus (Brake Assist Plus) - Mercedes.

Dabere na akara sitere na ihe mmetụta, ECU na-agbanye mgbapụta hydraulic nke usoro ESC ma mee ka nrụgide dị na sistemụ breeki ruo uru kachasị.

Na mgbakwunye ọsọ nke etinyere breeki ahụ, SBC na-eburu nrụgide dị na pedal ahụ, ihu ụzọ, ụzọ njem, na ihe ndị ọzọ. Dabere na ọnọdụ a kapịrị ọnụ, ECU na-ewepụta ikike braking kachasị mma maka wiil ọ bụla.

Mgbanwe BA Plus na-echebara ụzọ ụgbọ ala dị n'ihu. N'ọnọdụ nke ihe egwu, ọ na-adọ onye ọkwọ ụgbọala aka na ntị, ma ọ bụ brek ya.

Automatic mberede braking usoro

Usoro mberede braking nke ụdị a dị elu. Ọ na-achọpụta ụgbọ dị n'ihu ma ọ bụ ihe mgbochi na-eji radar na igwefoto vidiyo. Ihe mgbagwoju anya n’onwe ya na-agbakọ ihe dị n’ime ụgbọ ala ahụ ma ọ bụrụ na ihe mberede puru omume na-ebelata ọsọ. Ọbụna na nkwekọrịta nwere ike ime, nsonaazụ ya agaghị adị oke njọ.

Na mgbakwunye na braking mberede na-akpaghị aka, ngwaọrụ nwere ọrụ ndị ọzọ. Dị ka: ịdọ aka ná ntị onye ọkwọ ụgbọala banyere ihe ọghọm nke nkwekọrịta site na ụda na mgbaàmà ọkụ. Ọzọkwa, ụfọdụ ngwaọrụ nchekwa na-arụ ọrụ, n'ihi nke mgbagwoju ahụ nwere aha dị iche - "usoro nchekwa mgbochi".

Site na nhazi, ụdị usoro ihe mberede a na - adabere na sistemụ nchekwa ndị ọzọ na - arụ ọrụ:

  • na-agbanwegharị ụgbọ mmiri (njikwa anya);
  • ọnụego mgbanwe ego (akpaka braking).

Typesdị ụdị usoro mberede ihe mberede akpaka mara:

  • Ebube Nzuzo Nzuzo - maka Mercedes;
  • Mkpokọta Mitigation Braking System, CMBS dị maka ụgbọ ala Honda;
  • City breeki Control - Фиат;
  • Ọrụ City Stop na Forward Alert - arụnyere na Ford;
  • Gbanwee Mkpokọta Mgbochi, FCM- Mitsubishi;
  • Obodo Mberede Obodo - Volkswagen;
  • Nchedo Obodo dị maka Volvo.
