Working brake mechanism. Iyo inorongwa sei uye inoshanda sei

Takatonyora pamusoro pezvakawanda, ndeapi matambudziko angamuka nawo, uye kuti ungaziva sei matambudziko anogona kuitika nemabhureki. Iye zvino ngatitaurei zvishoma pamusoro pechinhu chakakosha zvakadaro chegadziriro se actuator uye chikamu chayo chinokosha - silinda inoshanda.

Zvishoma nezve mabhureki zvakazara uye basa rehumburumbira yevaranda mukushandiswa kwebhureki

Munenge chero mota yevafambi, iyo executive brake mechanism inogadziriswa hydraulically. Mune chimiro chakareruka, mabhureki maitiro ndeaya anotevera.

Tsoka inotsika pabhureki (3). Iyo pusher (4) yakabatana kune pedal inomisa main brake cylinder (GTZ) (6). Piston yayo inotambanuka nekusundidzira brake fluid mumitsetse (9, 10) yehydraulic system. Nekuda kwekuti iyo mvura haina kumanikidza zvachose, kumanikidza kunobva kwaendeswa kune vhiri (kushanda) masilinda (2, 8), uye piston yavo inotanga kufamba.

Ndiyo silinda yekushanda ine piston yayo inobata zvakananga pane actuator. Nekuda kweizvozvo, mapadhi (1, 7) anotsikirirwa padhisiki kana chigubhu, zvichiita kuti vhiri ripuke.

Kusunungura pedal kunotungamirira kudonho mukudzvinyirira muhurongwa, mapistoni anofamba mumasilinda, uye mapedhi anofamba kubva pa diski (drum) nekuda kwezvitubu zvekudzoka.

Zvinonyanya kuderedza simba rinodiwa rekutsikirira pedal uye kuvandudza kushanda kwegadziriro yose inobvumira kushandiswa kwevacuum booster. Kazhinji imodule imwe chete neGTZ. Nekudaro, mamwe ma hydraulic actuators anogona kunge asina amplifier.

Iyo hydraulic system inopa kushanda kwepamusoro, nekukurumidza mabhureki mhinduro uye panguva imwechete ine yakapusa uye yakanakira dhizaini.

Mukutakura kutakura zvinhu, pneumatic kana yakasanganiswa system inowanzoshandiswa panzvimbo ye hydraulics, kunyange zvazvo nheyo dzekutanga dzekushanda kwayo dzakafanana.

Kusiyana kwe hydraulic drive schemes

Pamotokari dzinotakura vanhu, iyo brake system inowanzo patsanurwa kuita maviri hydraulic maseketi anoshanda akazvimirira ega. Kazhinji, maviri-chikamu GTZ anoshandiswa - kutaura zvazviri, aya maviri akapatsanurwa masilinda akasanganiswa kuita imwechete module uye ane yakajairika pusher. Kunyangwe paine mhando dzemakina uko maviri GTZ akaiswa ane yakajairika pedal drive.

Diagonal inoonekwa seyakanyanya chirongwa. Mariri, imwe yemasekete ine basa rekubhureki kuruboshwe uye kurudyi mavhiri kumashure, uye yechipiri inoshanda nemamwe mavhiri maviri - diagonally. Ichi ndicho chirongwa chekushanda kwemabhureki chinogona kuwanikwa kazhinji pamotokari dzinotakura vanhu. Dzimwe nguva, pamotokari dzemashure-mavhiri, imwe nzira yekuvaka inoshandiswa inoshandiswa: imwe yedunhu kune mavhiri ekumashure, yechipiri kune mavhiri epamberi. Izvo zvakare zvinogoneka kusanganisa ese mavhiri mana mudunhu guru uye zvakasiyana mavhiri maviri epamberi mune backup.

Kune masisitimu ekuti vhiri rega rega rine macylinders maviri kana matatu anoshanda.

Zvingave zvakadaro, kuvepo kwemaviri akaparadzana akazvimirira anoshanda hydraulic maseketi kunowedzera kutadza-kuchengetedzeka kwemabhureki uye kunoita kuti kutyaira kuve kwakachengeteka, nekuti kana imwe yemaseketi ikatadza (semuenzaniso, nekuda kwekudonha kwebrake fluid), yechipiri ichaita. zvinoita kumisa mota. Zvakangodaro, kushanda kwebhureki kwakati kwakadzikira mune iyi kesi, saka, hapana nyaya inofanira kunonoka kugadzirisa mamiriro aya.

Dhizaini maitiro emabhureki michina

Pamotokari dzinotakura vanhu, friction actuators inoshandiswa, uye braking inoitwa nekuda kwekukweshana kwemapadhi achipesana ne disc kana mukati medhiramu remabhureki.

Kune mavhiri epamberi, dhisiki-mhando michina inoshandiswa. Iyo caliper, iyo yakasungirirwa pachitsiko chekutungamira, inogara imwe kana maviri silinda, pamwe nemabhureki mapedhi.

Inotaridzika senge silinda inoshanda ye disc brake mechanism.

Panguva yebraking, fluid pressure inosundira mapiston kubva mumacylinders. Kazhinji mapistoni anoita zvakananga pamapedhi, kunyangwe paine magadzirirwo ane yakakosha kutapurirana michina.

Iyo caliper, yakafanana nebhuraketi muchimiro, inogadzirwa nesimbi yakakandwa kana aluminium. Mune mamwe magadzirirwo anogadziriswa, mune mamwe ari mobile. Mushanduro yekutanga, macylinders maviri akaiswa mairi, uye mapedhi anotsikirirwa kurwisana nebhureki disc nepiston kumativi ose maviri. Iyo caliper inofambiswa inogona kufamba pamwe nemadhairekitori uye ine imwe silinda inoshanda. Mukugadzirwa uku, ma hydraulics anonyatso kudzora kwete piston chete, asiwo caliper.

Iyo inofambiswa vhezheni inopa yakawedzera kupfekwa kweiyo friction linings uye inogara gap pakati pe disc uye pad, asi iyo static caliper dhizaini inopa zvirinani braking.

Iyo dhiramu-mhando actuator, iyo inowanzoshandiswa kumavhiri ekumashure, yakarongedzwa neimwe nzira.

Masilinda anoshanda akasiyanawo pano. Vane mapiston maviri ane simbi yekusundidzira. Kuisa chisimbiso cuffs uye anthers kunodzivirira kupinda kwemhepo uye zvidimbu zvekunze mucylinder uye kudzivirira kupera kwayo nguva isati yakwana. Kukodzera kwakakosha kunoshandiswa kuburitsa mweya kana uchipomba ma hydraulics.

Pakati pechikamu pane mhango, mukugadzirisa mabhureki yakazadzwa nemvura. Nekuda kweizvozvo, mapistoni anosundirwa kunze kweakatarisana mativi ehumburumbira uye kuisa kumanikidza pamabhureki mapedhi. Idzo dzinodzvinyirirwa pamusoro pedhiramu rinotenderera kubva mukati, zvichideredza kutenderera kwevhiri.

Mune mamwe mamodheru emakina, kuti awedzere kugona kwedhiramu mabhureki, maviri macylinders anoshanda anosanganisirwa mukugadzira kwawo.

Diagnostics

Kunyanya kupfava kudzvinyirira kana kutadza kwebhureki pedal zvinogoneka nekuda kwekuora mwoyo kweiyo hydraulic system kana kuvapo kwemhepo inoputika mairi. Kukanganisa kweGTZ hakugone kubviswa mumamiriro ezvinhu aya.

Kuwedzera pedal kuoma kunoratidza kutadza kwevacuum booster.

Zvimwe zviratidzo zvisina kunanga zvinotibvumira kugumisa kuti mavhirijiri haasi kushanda nemazvo.

Kana motokari ichisvetuka panguva yekuputika, zvino zvingangoita kuti piston ye silinda yekushanda yeimwe yemavhiri inoputika. Kana yakanamatira munzvimbo yakawedzerwa, inogona kudzvanya padhi ichipokana ne disc, zvichikonzera kubhuroka zvachose kwevhiri. Ipapo motokari inofamba inogona kutungamirira kudivi, matai achasakara zvisina kuenzana, uye kudengenyeka kunogona kunzwika pachidhiraivho. Zvinofanira kurangarirwa kuti kubatwa kwepiston dzimwe nguva kunogona kukonzereswa nemapedhi akapfekwa zvakanyanya.

Iwe unogona kuedza kudzorera chivharo chekushanda chinokanganisa, semuenzaniso, uchishandisa yakakodzera kugadzirisa kit. Kana izvi zvisingabviri, saka iwe unofanirwa kutenga chikamu chitsva chinoenderana nemota yako modhi. Chitoro cheChinese online chine sarudzo yakakura yemotokari dzeChinese, pamwe nezvikamu zvemotokari dzakagadzirwa neEurope.
