Machitidwe a braking mwadzidzidzi

Chimodzi mwazida zazikulu zomwe zimapewa ngozi kapena kuchepetsa zotsatira zake ndi njira yama braking yadzidzidzi. Ndikofunikira kuti magwiridwe antchito a braking azikhala ovuta: pafupifupi, mtunda wamagalimoto wamagalimoto amachepetsedwa ndi magawo makumi awiri peresenti. Kwenikweni BAS kapena wothandizira wa Brake amatha kutanthauziridwa kuti "wothandizira mabuleki". Njira yothandizira mabuleki mwadzidzidzi (kutengera mtundu) imathandizira dalaivala popumira mwadzidzidzi (mwa "kukanikiza" brake pedal), kapena amangoimitsa galimotoyo osayendetsa dalaivala mpaka itayima. M'nkhaniyi tikambirana za chipangizocho, momwe amagwirira ntchito ndi mitundu ya machitidwe awiriwa.

Mitundu yosiyanasiyana yama braking othandiza mwadzidzidzi

Pali magulu awiri azinthu zadzidzidzi zothandizira ma braking:

• thandizo la braking mwadzidzidzi;
• zodziwikiratu braking mwadzidzidzi.

Yoyamba imapangitsa kuti mabuleki azithamanga kwambiri chifukwa choti dalaivala akukakamiza kuphika. Pamenepo, "mabuleki" a dalaivala. Chachiwiri chimagwira ntchito yomweyo, koma osayendetsa dalaivala. Izi zimachitika zokha.

Dongosolo lothandizidwa ndi braking mwadzidzidzi

Kutengera ndi mfundo yopanga kuthamanga kwakukulu kwa mabuleki, mtundu uwu wagawidwa pneumatic ndi hydraulic.

Pneumatic Emergency Brake Aid

Dongosolo pneumatic zipangitsa dzuwa pazipita chilimbikitso zingalowe ananyema. Amakhala ndi zinthu zotsatirazi:

1. kachipangizo kamene kali mkati mwa chopukusira chazitsulo ndikuyesa kuthamanga kwa ndodo yamphamvu;
2. mu atomu ndodo pagalimoto;
3. zamagetsi zamagetsi (ECU).

Mtundu wa pneumatic umayikidwa makamaka pagalimoto zokhala ndi ma anti-loko braking system (ABS).

Mfundo ya dongosololi idakhazikitsidwa potengera kuzindikira kuti mabuleki azidzidzimutsa ndi othamanga kwambiri pomwe dalaivala amasindikiza cholembera. Kuthamanga uku kumalembedwa ndi sensa, yomwe imatumiza zotsatira zake ku makina owongolera zamagetsi. Ngati chizindikirocho chili chachikulu kuposa mtengo woikidwiratu, ECU imayendetsa ndodo yoyendetsa ndodo. Chowonjezera chotsalira chotsalira chimakanikizira chidutswa chazitsulo poyimitsa. Ngakhale ABS isanayambike, kusweka kwadzidzidzi kumachitika.

Njira zothandizila mabuleki mwadzidzidzi ndizo:

• BA (Chothandizira Cha Brake);
• BAS (Njira Yothandizira Brake);
• EBA (Emergency Brake Assist) - yoyika pa Volvo, Toyota, Mercedes, BMW magalimoto;
• AFU - kwa Citroen, Renault, Peugeot.

Hayidiroliki Emergency ananyema Kuthandiza

Mtundu wama hydroli wa "break assist" umapangitsa kuti madzi asamayende bwino chifukwa chobedwa chifukwa cha zinthu za ESC (Vehicle Stability Control).

Kapangidwe, dongosolo ili ndi:

1. ananyema kuthamanga sensa;
2. chojambulira liwiro lamagudumu kapena chojambulira chopumira pazowonjezera;
3. ananyema kuwala lophimba;
4. ECU.

Njirayi ilinso ndi mitundu ingapo:

• HBA (Hydraulic Braking Assistance) imayikidwa pa Volkswagen, Audi;
• HBB (Hydraulic Brake Booster) imayikidwanso pa Audi ndi Volkswagen;
• SBC (Sensotronic Brake Control) - yopangidwira Mercedes;
• DBC (Dynamic Brake Control) - ikani BMW;
• BA Plus (Brake assist Plus) - Мерседес.

Kutengera ndi zizindikilo zochokera kumasensa, ECU imatsegula mpope wama hydraulic wa dongosolo la ESC ndikuwonjezera kukakamiza kwamabuleki mpaka mtengo wokwera.

Kuphatikiza pa liwiro lomwe kuphwanya kwa mabuleki kumakhala kovutikira, dongosolo la SBC limaganiziranso kukakamira kwa pakhwalapo, msewu, mayendedwe aulendo, ndi zinthu zina. Kutengera ndi momwe zinthu zilili, ECU imapanga batire yoyenda bwino pagudumu lililonse.

Kusiyanasiyana kwa BA Plus kumaganiziranso mtunda wa galimoto yomwe ikubwera. Pakakhala zoopsa, amachenjeza woyendetsa, kapena mabuleki.

Makinawa mwadzidzidzi braking dongosolo

Makina abwinobwino amtunduwu ndiotsogola kwambiri. Imazindikira galimoto yakutsogolo kapena chopinga chogwiritsa ntchito radar ndi kamera ya kanema. Zovutazo zimadziyimira pawokha mtunda wa galimotoyo, ndipo zikachitika ngozi, amachepetsa kuthamanga. Ngakhale kugundana kotheka, zotsatira zake sizikhala zazikulu.

Kuphatikiza pa braking yadzidzidzi, chipangizocho chili ndi ntchito zina. Monga: kuchenjeza dalaivala za ngozi yoti adzagunda mwa kuwulutsa mawu ndi kuwunikira. Komanso, zida zina zachitetezo zokhazokha zimayambitsidwa, chifukwa chake zovuta zimakhala ndi dzina lina - "njira yodzitetezera".

Mwadongosolo, mtundu uwu wama braking mwadzidzidzi umakhazikitsidwa ndi machitidwe ena otetezera:

• kusintha kwamaulendo oyenda pamtunda (kuwongolera mtunda);
• kusinthasintha kwa ndalama (kusinthitsa mwachangu).

Mitundu yotsatirayi yama braking yadzidzidzi imadziwika:

• Pre-Safe Brake - ya Mercedes;
• Kugundana Kwakuchepetsa Braking System, CMBS imagwira ntchito pagalimoto ya Honda;
• Kulamulira kwa City City - Фиат;
• Yogwira City Lekani ndi Forward Alert - anaika pa Ford;
• Kupititsa Patsogolo Kugunda, FCM- Mitsubishi;
• City Emergency Brake - Volkswagen;
• City Safety imagwiranso ntchito kwa Volvo.
