braking system. Nzira yekuitarisira sei?
Iyo braking system pasina mubvunzo chimwe chezvinhu zvakakosha zvemota, zvinokanganisa zvakananga kunaka uye kuchengetedzwa kwekutyaira.
Muchinyorwa chemazuva ano, tichaedza kuratidza matambudziko akajairika, malfunctions uye nheyo dzakakosha dzekushanda kwakaringana kwebhureki system. Kunyanya, isu tichataura nezve brake pads uye discs.
Kutanga, dzidziso shoma - braking simba inodiwa kubhureka mota. Nekuumbwa kwayo, zvinodikanwa kugadzira braking torque pavhiri. Braking torque chikamu chesimba rinoshandiswa uye lever pairi kuita. Iyo hydraulic braking system ine basa rekushandisa simba nekuiendesa kumadhisiki kuburikidza nemabhureki pads. Iyo disc irevheti, saka iyo yakakura iyo dhayamita yedhisiki, iyo yakakura iyo torque yebhureki inogadzirwa.
Iyo braking process pachayo inoshandura kinetic simba remotokari inofamba kuita simba rinopisa rinogadzirwa nekukwesha kwemabhureki padhi pamadisiki. Kuwanda kwesimba rekupisa kwakakosha. Mumotokari yevagari vemo, unogona kupisa zviri nyore kudzvanya-block-disk system kusvika 350 degrees Celsius! Ndicho chikonzero nei ma discs anowanzo gadzirwa negrey cast iron. Ichi chinyorwa chinoratidzwa neyakanaka kwazvo yekupisa conductivity uye nyore kwekugadzira yakaoma castings. Iyo yakakura iyo dhayamita yedhisiki, iyo yakanyanya kupisa iyo inogona kusveta uye iyo inoshanda zvakanyanya iyo braking maitiro anogona kuve. Zvisinei, kuwedzera kwehupamhi hwe diski kunokonzera kuwedzera kwehuwandu hwayo, uye iyi ndiyo inonzi "Unssprung mass", ndiko kuti, chii chisingafukidzwi nekusimiswa. Kunyaradza kwekufamba uye kusimba kwezvitubu-zvinonyorovesa zvinhu ivo pachavo zvinoenderana neizvi.

Naizvozvo, vagadziri vanoedza kutsvaga kupindirana pakati pesimba iro piston inotsikirira pabhureki padhi uye saizi yebhureki padhi uye disc. Mukuwedzera, vagadziri vari kuedza nenzira dzakasiyana-siyana kuti vabvise kupisa kunowedzera pane dial. Iyo friction surface inodonhedzwa (kuburikidza) kana ribbed pakati pekushanda kwema disks (iyo inonzi ventilated disks). Zvose muzita rekuwedzera kupisa kupisa.
Panyaya yemadhisiki akagadzirirwa mitambo kana kushandiswa kwakanyanya, vagadziri vanowanzo dhiza kana kucheka nzvimbo yebasa kusvika pakadzika yakatemerwa kufambisa kubviswa kwemagasi anogadzirwa nekukwesha kwezvikamu zvehurongwa. Iwo notches anonatsa zvakare tsvina inounganidza pamapadhi uye inocheka tangential pamusoro pemapadhi kuitira kuti padhi igare yakachena uye inonamatira zvakanaka kune disc. Kukanganisa kwemhinduro iyi ndiko kukurumidza kupfeka kwemabrake pads.
Nezve mabhureki pads, isu tinosiyanisa mhando ina huru zvichienderana nechinhu icho chikamu chavo chekukwesha chinogadzirwa:
semi-metal - iyo yakachipa, yakanyanya ruzha. Vanotamisa kupisa zvakanaka, izvo zvinovandudza braking kunyatsoshanda. Iyo yekupfeka inogadzirwa nesimbi, waya, mhangura, graphite, nezvimwe.
asbestos (LLW) - girazi, rabha, kabhoni yakasungwa neresin. Ivo vakanyarara asi vasina kusimba kupfuura avo semi-metal vamwe vavo. Madhisiki ane huruva zvikuru.
low-metal (LLW) - lining of organic compounds ine diki musanganiswa wesimbi (mhangura kana simbi). Dzinoshanda zvakanyanya asi dzine ruzha.
ceramic - inodhura zvakanyanya kana ichienzaniswa nemhando dziri pamusoro pemabhuroko. Izvo zvinogadzirwa kubva kune ceramic fibers, fillers uye binders. Mune zvimwe zviitiko, anogonawo kunge aine zvidiki zvesimbi. Iwo akanyarara uye akachena uye ane bhenefiti yakawedzerwa yekusakuvadza mabhureki disc.
Ndeapi matambudziko atingasangana nawo pakushandisa braking system?
Ngatitangei nezvataurwa pamusoro pesimba rekupisa. Kana tikadziya madhisiki kune ambotaurwa 300-350 madhigirii celsius (mashoma mabhureki ane simba kubva pa60 km/h kusvika pakamira akazara anokwana), tobva tatyaira tichipinda mugomba rakadzika, tine mukana wakanyanya wekuti tichaona. pulsation pane brake pedal. nemabhureki ega ega anotevera. Kudurura madhisiki nemvura kunoita kuti akurumidze kutonhora zvisina kuenzana, izvo zvinotungamira mukukotama kwavo. Disiki rinopwanya rinodzvanya pabhureki, zvichikonzera kusanzwa kusingafadzi pabhureki pedal uye kuzunguzika kwevhiri. Panogonawo kunge paine "kick" yemota kana ichibhureki.
Saka dzivirira kutyaira nemumapuddles akadzika - mabhureki discs edu uye zvimwe zvikamu zvine chokwadi chekuzvibhadharira mukushandisa kwenguva refu.
Tinogona kuedza kuchengetedza warped brake disc nekuitenderedza. Mutengo wesevhisi yakadai ndeye PLN zana nemakumi mashanu pa axle. Maitiro akadai ane musoro panyaya yecurvature yemadhisiki matsva. Mushure mekukunguruka, disc inofanira kunge iine hushoma hwekushanda ukobvu hunotsanangurwa nemugadziri. Zvikasadaro, iwe unofanirwa kutenga seti yemasaha blades paaxle.

Sei hudiki hudiki hwekushanda hunofanirwa kutevedzwa zvakanyanya?
Kunyanya kutetepa, dhisiki rakasakara harisisina kukwana kwekupisa. Iyo system inopisa nekukurumidza uye kana paine emergency braking, unogona kuerekana warasikirwa nesimba rekubhureki.
Kunyanya kutetepa dhisiki rinowanzoita kutsemuka.
Radial disc fracture inozokonzera kugunun'una kunozowedzera muhuwandu sezvo kutenderera kunowedzera. Mukuwedzera, panguva yakadzikama braking, pulsation ye brake pedal inogona kuitika.
Dhisiki yakasakara inogonawo kukonzera kutsemuka kwe circumferential. Rudzi urwu rwekutsemuka kune ngozi zvakanyanya. Nekuda kweizvozvo, nzvimbo yekushanda ye disc inogona kudonha kubva pagumbo hub!
Rimwe dambudziko rinogona kukanganisa mabhureki disc is surface corrosion. Izvi hazvishamisi, kunyanya kana mhepo yakanyorova zvakanyanya kana kuti tinotyaira mumigwagwa yakasaswa nemunyu womumugwagwa. Iyo ngura inovhara inobuda mushure mekutanga bhureki, asi isu tinofanira kuyeuka kuti kusvika ngura yabva, mabhureki edu anonyatso shanda. Corrosion pamadhisiki inogona kucherechedzwa nehunhu hunoitwa nemotokari kana ichibhureki kekutanga mushure mekumira kwenguva refu. Hunhu, pane ruzha rukuru rwekukweshana kunoratidza kuti mapadhi ari kukwenya ngura kubva kumadhisiki.
Imwe dambudziko neiyo brake system ndeye squeak isingafadzi. Izvi zvinowanzo ratidza kupfeka kwakanyanya kweiyo friction elements ye system. Zvikamu zvesimbi zvebrake pad zvinotanga kukwesha padisc, zvichirira, zvichikonzera ruzha rwakanyanya, runonyangadza kana kukwenya ruzha. Muchiitiko ichi, hapana imwe sarudzo kunze kwekutsiva zvinhu zvakasakara. Kutsiviwa kunofanira kuitwa nekukurumidza sezvinobvira, sezvo kukweshera kwesimbi zvinhu pane dhisiki yataurwa pamusoro apa kunogona kutungamirira kukukuvara kusingachinjiki kune disc. Muchiitiko chekukurumidza kugadzirisa, kugadzirisa kunogona kupera nekutsiviwa kwemapadhi pachavo. Brake squealing inogonawo kukonzerwa nenzvimbo dzakasvibiswa pamadhisiki uye pads pachavo. Muchiitiko ichi, kuchenesa sisitimu neinonzi Brake Cleaner kunofanira kubatsira, iyo inozobvisa uye kuchenesa madhisiki uye brake pads.
Ndeapi matambudziko angave nemabrake pads?
Chokutanga pane zvose, mapedhi anogona kupisa. Iyo yakaonda, iyo yakanyanya kupfekwa iyo gasket, inoderedza kushorwa kwayo kune yakanyanya kupisa. Muchiitiko chekupisa, chinhu chinosunga friction chinopisa padhi. Iyo padhi ine kushomeka kushoma kana yasangana ne disc, iyo inoderedza braking simba uye kusimba. Mukuwedzera, zvinogona kukonzera kushungurudza squeals.
Chekupedzisira, tinofanira kutaura zvikanganiso zvinowanzoitika nevatyairi, izvo zvinoderedza zvakanyanya kusimba kweiyo braking system. Chikonzero chinonyanyozivikanwa inyanzvi yekutyaira isina kunaka. Kurebesa mabhureki pamawere, kureba kudzika uye kugara uchichengeta tsoka yako pabhureki pedal inotungamira mukupisa kusingadzivisike kweiyo system. Paunenge uchityaira munzvimbo ine makomo, yeuka kushandisa bhureki reinjini uye, kana zvichibvira, shandisa nzira yekupfupika uye yakaoma mabhureki uye kuregedza kwechinguvana bhureki rinobvumira kuti system itonhore.
Senguva dzose, zvakakosha kutaura nezvekudzivirira. Pakuongorora kwese kunokwanisa, tinoda makanika kuti aongorore mabhureki system! Ichi chakareruka, chinogara chichishandiswa sevhisi chiitiko chichava nemhedzisiro yakanaka pakuchengetedza kwedu, kunyaradza kwekutyaira uye mamiriro echikwama chedu.
