Kodi brake booster ndi chiyani? Kodi brake booster imagwira ntchito bwanji?

Ngati mukufuna kudziwa chomwe chiwongolero cha brake ndi momwe chimakhudzira magwiridwe antchito a brake system, muyenera kuwerenga nkhani yathu yokhudza chinthu chosadziwika bwino chomwe chili mugalimoto iliyonse yokhala ndi chiwongolero chamagetsi. Tikukulimbikitsani kuti muwerenge malemba otsatirawa kuti mudziwe momwe mungasamalire chowonjezera cha brake ndi momwe mungagwiritsire ntchito mokwanira.

Brake booster - ndichiyani?

The brake booster ndi chinthu chofunikira kwambiri m'galimoto yomwe madalaivala ambiri amadziwa, koma sadziwa chomwe gawo ili lagalimoto limayang'anira komanso kufunikira kwake pakuyendetsa chitetezo.

Ma brake system amadalira madzimadzi omwe ali mu posungira ndi ma hoses. The braking ndondomeko palokha akhoza kukhala chosavuta ndi kukanikiza ananyema pedal, amene kumawonjezera kuthamanga madzimadzi, amaika kukakamiza calipers ndi zimbale. Chifukwa cha zimenezi, galimotoyo inaima. Panjira, komabe, chowonjezera cha brake chimagwira ntchito yofunika kwambiri. Popanda izo, kutsika mabuleki kukanakhala kovuta kwambiri, ndipo panthawi imodzimodziyo kumawonjezera ngozi pamsewu.

Brake booster palokha ndiyopanda kukonza ndipo sichitha nthawi zambiri. Kuphatikiza apo, ndi imodzi mwazinthu zotsika mtengo zosinthira. Pa nthawi imodzimodziyo, ndi yanzeru m'kuphweka kwake ndi luso lake. Linapangidwa mu 1927 ndi injiniya Albert Devandre. Bosch ndiye adagula patent kwa iye ndikuigawa ngati cholimbikitsira mabuleki.

Ntchito ya servo ndikuwonjezera kukakamiza kwa pistoni ya silinda. Izi zimapangitsa kugwiritsa ntchito mphamvu zonse za braking system. Chotsatira chake, simukuyenera kukanikiza mwamphamvu pa chopondapo cha brake, chifukwa dongosolo limayankha ndi braking yoyenera, yomwe imagwirizana mwachindunji ndi zolinga za dalaivala.

Kodi brake booster imawoneka bwanji?

Chiwongolero cha brake chingayerekezedwe ndi chimbale, chophwanyika kapena ng'oma. Ili pafupi ndi gawo la chipinda cha injini kumbali ya chiwongolero. Mudzapeza kuseri kwa nkhokwe ya brake fluid monga servo yomwe imalumikizidwa nayo. Imawonjezera mphamvu yomwe imagwira pa master silinda piston pomwe dalaivala akanikizira ma brake pedal.

Chowonjezera cha brake chili ndi zipinda ziwiri mkati, zomwe zimasiyanitsidwa ndi diaphragm yosindikizidwa. Mmodzi wa iwo chikugwirizana ndi cholowera chitoliro cha zobweza zambiri, amene kumawonjezera braking mphamvu. Amalumikizidwanso ndi njira ya mpweya, kotero kuti vacuum mkati mwawo ndi njira yolowera imakhalabe pamlingo womwewo.

Kodi ma brake booster ndi chiyani?

Mwachidule, brake booster imapangitsa kuti braking ikhale yotetezeka, yogwira ntchito komanso yotsika mtengo. Ntchito yake imayamba pomwe chopondapo cha brake chikanikizidwa. Imagwiritsa ntchito kukakamiza kwa silinda ya master, yomwe imatsegula valavu, ndikulola kuti vacuum yochokera kumitundu yambiri igwire ntchito pa diaphragm. Chifukwa cha iye, mphamvu yomwe imagwira pa diaphragm imagwirizana mwachindunji ndi mphamvu ya dalaivala pa brake pedal. Zotsatira zake, zimatha kusintha mphamvu ya braking. Mwanjira imeneyi, ndizotheka kuletsa dalaivala kuti asavutike pang'ono pa brake pedal ndikugwiritsa ntchito makinawo mwachangu kwambiri.

The servo alibe kukonza ndipo si mbali ya mwadzidzidzi galimoto. Zowonongeka nthawi zambiri zimawonekera ndi kutuluka kwa mabuleki kapena ma brake pedal.

Thandizo la mabuleki ndilofunika kwambiri pankhani yoyendetsa bwino. Panthawi imodzimodziyo, imamveka ndi madalaivala pokhapokha ngati palibe.. Mwachitsanzo, mukakoka galimoto itazimitsa injini, mutha kumva mwachangu momwe zingakhalire kuyendetsa galimoto popanda chothandizira mabuleki. Ma brake pedal ndizovuta kwambiri kukanikiza ndipo amauma pakapita nthawi yochepa. Kuyenda kwa pedal kudzachepetsedwa kwambiri, zomwe zimapangitsa kuti zikhale zovuta kuswa. Izi ndichifukwa cha kusowa kwamphamvu kokwanira mu ma brake system, omwe amapangidwa chifukwa cha ntchito ya brake booster.

Brake servo - ntchito

Chowonjezera cha brake chili ndi zipinda ziwiri (zosasokonezedwa ndi chipinda cha injini), zomwe zimasiyanitsidwa ndi nembanemba ya rabara. Chipinda chachikulu chimakhala pansi pa kupanikizika koipa, pamene chaching'onocho chimakhala ndi njira yolumikizira mlengalenga, kotero kuti chimakhala ndi mphamvu ya mumlengalenga.. Pakati pawo pali njira, yomwe imakhala yotseguka nthawi zambiri. Zotsatira zake, kupanikizika koipa kumapangidwa mu chipangizo chonsecho. Komabe, panthawi ya braking, mutatha kukanikiza chopondapo, valavu imatseka njira yolumikizira zipinda ziwiri, ndipo chipinda chaching'ono chimatsegulidwa. Chifukwa chake, kupanikizika kumakwera kwambiri, chifukwa chomwe diaphragm imayamba kupita kuchipinda chachikulu. Pampu ya brake imathandizira ndi izi, pomwe pisitoni imachita ndi mphamvu yowonjezereka.

Ndikoyenera kudziwa kuti chinthu chilichonse cha brake booster system chimagwiritsa ntchito vacuum kuti igwire bwino ntchito. Kupanda kutero, brake pedal idzakhala yolimba komanso yosagwira ntchito. Kuonjezera apo, zinthu zina zimagwirizanitsidwa ndi malo a pedal, kotero kuti ali ndi zofanana mu malo a piston ya brake. Motero, galimotoyo imathyoka ndi mphamvu yodziwika ndi dalaivala. Kuphatikiza apo, transducer yoyendetsedwa ndi servo imagwiritsidwa ntchito kuti isunge kupanikizika koyenera mu dongosolo lonselo.

Njira yomwe tafotokozayi imagwiritsidwa ntchito mu injini zamafuta. Kumbali inayi, ma injini a dizilo, ma turbocharged ndi magalimoto amagetsi amagwiritsanso ntchito pampu ya vacuum yomwe imayendetsedwa ndi makina kapena magetsi.

Pankhani ya brake booster, zinthu zimasiyana ngakhale pamagalimoto. Pankhani ya magalimoto akuluakulu oterowo, chipangizo chophatikizira chothandizira cholimbikitsira chimagwiritsidwa ntchito. Amagwiritsa ntchito mpweya woponderezedwa.

Kodi mungazindikire bwanji kulephera kwa seva?

Nthawi zambiri, kulephera kwa brake booster kumatha kuzindikirika ndi cholimba komanso chovuta kukakamiza ma brake pedal, pomwe sitiroko ikakanikizidwa, imafupikitsidwa kwambiri. Ngati munasweka ndi injini yozimitsa, izi ndizabwinobwino.. Komabe, ngati izi zikuchitika injini ikugwira ntchito, mungakhale otsimikiza kuti chowonjezera cha brake chalephera.

Ndikoyeneranso kuyang'ana malo anu a brake fluid chifukwa kutayikira kungakhale kovuta. Izi zikuwonetsa kutayikira kwadongosolo, kotero kuyendetsa kwina kumatha kulumikizidwa ndi chiwopsezo chowonjezereka komanso kuchepa kwa mabuleki. Phokoso lachilendo panthawi ya braking lingasonyezenso kuti chinachake chalakwika ndi dongosolo ndipo muyenera kulankhulana ndi katswiri. Pakawonongeka kwa brake booster, iyenera kusinthidwa yonse, chifukwa ichi ndi chipangizo chopanda kukonza. Mwamwayi, imasweka kawirikawiri, ndipo mtengo wake siwokwera kwambiri.

Nthawi zambiri vuto lingakhalenso chingwe chowonongeka cha vacuum chomwe chimataya katundu wake wothandizira pamene chikutuluka. Zolakwa zina zokhudzana ndi ma brake system ndi brake booster ndi vuto la valavu yoyendera, kusankha kosayenera kwa chowonjezera pa chipangizo cholakwika, ndikuyika mzere wopumira wa mainchesi olakwika.

Momwe mungayang'anire mkhalidwe wa brake booster?

Mukhoza kuyesa chilimbikitso cha brake nokha muzochita. Zomwe muyenera kuchita ndikuwongolera mtunda wa braking ndi kuthamanga kofunikira kuti galimotoyo iime. Komanso, mutha kubwezeretsanso brake booster nokha. Ngati muwona vuto lililonse ndi brake booster yanu, ikani ndalama zatsopano ndikuzisintha nthawi yomweyo chifukwa ma braking system ndi ofunikira kuti muyendetse bwino.

Mumadziwa kale chomwe chiwongolero cha brake ndi chomwe gawo ili la brake system ndi la. Ngakhale miyeso yake yanzeru, ndi chinthu chofunikira kwambiri pagalimoto iliyonse, chifukwa chitetezo, mphamvu ya braking ndi chitonthozo cha dalaivala zimadalira. Popanda chowonjezera mabuleki, kuyendetsa galimoto kungakhale kovuta kwambiri. Kuphatikiza apo, madalaivala atha kukhala ndi vuto losintha kukakamizidwa kwa ma brake pedal kuti agwirizane ndi zomwe zikuchitika komanso zofunikira pazochitika zinazake.
