Parking brake - kuti inoshanda sei uye inoshanda sei

Motokari, mavhiri anotakura mutyairi nevatyairi, pane chidhiraivho chekudzora mavhiri aya, injini yekutyaira, uye mabhureki kuti amire, chinova chinhu chikuru pakuchengetedza. Siyanisai pakati peanoshanda mabhureki system neanobatsira, inova mabhureki ekupaka. Inozivikanwa zvakare sehandbrake kana kungoti "handbrake". Nemotokari dzemazuva ano, izwi rekuti bhuku rave kutove anachronism, sezvo vanotungamira automaker vari kuendesa handbrake drive kune zvemagetsi.

Mabhureki ekupaka akagadzirwa, sezvinoreva zita, kuti mota irambe yakamira paunenge uchipaka (kumira), kunyanya kana mugwagwa kana nzvimbo yekupaka ine materu. Nekudaro, iyi bhureki ichiri kushandiswa seye emergency brake system kana main brake inoshanda ikatadza. Ngatiedzei kunzwisisa dhizaini yekumisa mabhureki system. ngatione kuti zvinoshanda sei.

Nderipi: basa guru

Sezvakataurwa pamusoro apa, chinangwa chikuru chehandbrake ndechekuchengeta motokari panzvimbo panguva yekupaka kwenguva refu. Inoshandiswa sechinhu chekuwedzera chekudzora chekutyaira zvakanyanya, sechimbichimbi, sechigadziriso chebhureki mumamiriro ekukurumidzira.

Dhizaini ye "handbrake" yakajairwa - ndeye brake drive (munguva zhinji mekiniki), uye mabhureki meshini.

Ndeapi marudzi emabhureki

Iyo brake yekupaka inosiyana mumhando yekutyaira, yemhando huru dzatinocherekedza:

• mechanical drive (yakajairika);
• hydraulic (kazhinji kashoma;
• electromechanical EPB (bhatani panzvimbo ye lever).

Kuwanda kwema mechanical version kunokonzerwa nekureruka kwekugadzira uye kuvimbika kwepamusoro. Kuti uvhure mabhureki ekupaka, ingo dhonza lever kumusoro (kwauri). Panguva ino, tambo dzakatambanudzwa, nzira dzinovhara mavhiri, izvo zvinotungamirira kumira kana kuderera kwekukurumidza. Mumotokari nyowani dzine midziyo yakapfuma, sarudzo yechitatu iri kuwedzera kushandiswa, iyo hydraulic haina kujairika uye inonyanya kufarirwa nevanotyaira zvakanyanya.

Kune zvakare kupatsanurwa kwemamiriro kune nzira dzekubatanidzwa:

• Pane pedal (aka tsoka);
• Pane revere (ine revere).

Sezvo mutemo, iyo pedal "handbrake" inoshandiswa pamashini ane otomatiki kutapurirana. Iyo inoiswa neyechitatu pedal pachinzvimbo cheakanyangarika clutch pedal.

Nzira dzemabhureki dzinosiyanawo, uye dzinotevera:

• drum brake;
• cam;
• sikuruwa;
• kutapurirana (aka pakati).

Muchiitiko chekutanga, tambo, kutambanudza, kuita pane zvidhinha, izvo, zvakare, zvinomanikidzwa zvakasimba kurwisana nedhiramu, saka braking inoitika. Iyo yepakati yekupaka brake haivharidzi mavhiri, asi driveshaft. Mukuwedzera, kune motokari yemagetsi ine disk mechanism, iyo inotungamirirwa nemotokari yemagetsi.

Iri sei handbrake

Dhizaini yemabhureki ekupaka ine zvinhu zvitatu:

• Chaizvoizvo, iyo brake mechanism inosangana nemavhiri kana injini;
• Dhiraivha meshini inobata iyo brake mechanism (lever, bhatani, pedal);
• Cables kana hydraulic mitsetse.

Mune handbrake system, sekutonga, imwe kana matatu tambo inoshandiswa, iyo matatu-cable version ndiyo inonyanya kufarirwa uye yakavimbika. Iyo system ine tambo mbiri dzekumashure, imwe kumberi. Muchiitiko ichi, tambo mbiri dzekumashure dzinoenda kune brake mechanism, iyo yekumberi inopindirana nerevheti.

Kusungirirwa kana kusungirirwa kwetambo kunoitwa nezvinhu zvehandbrake uchishandisa akakosha anogadziriswa matipi. Zvakare, pane kugadzirisa nuts pamatambo, ayo iwe unogona kushandura kureba kwetambo pachayo. Kune zvakare chitubu chekudzoka mune system, iyo inodzosera iyo michina kunzvimbo yayo yekutanga mushure mekuburitswa kwehandbrake. Chitubu chekudzoka chinoiswa kana pane brake mechanism pachayo, pane yakaenzana kana patambo yakabatana kune lever.

Ainoita

Iyo brake inogadziriswa (mota inoiswa pa "handbrake") nekufambisa lever kune yakanyanya vertical chinzvimbo kudzamara kudzvanya kwehunhu hwelatch. Panguva imwecheteyo, tambo, kutambanudza, kudzvanya mapedhi akaiswa pamavhiri kumashure zvakasimba kumadhiramu. Mavhiri akavharwa nenzira iyi anotungamirira kumabhureki.

Kuti usunungure muchina kubva pahandbrake, zvinodikanwa kudzvanya bhatani rakabata latch, kudzikisa lever kunzvimbo yekutanga pasi (yakarara pasi).

Disc akamedura

Mota dzine dhisiki mabhureki kumativi ese dzine handbrake ine misiyano mishoma. Kune marudzi anotevera:

• screw brake;
• cam;
• dhiramu rakaputika.

Sarudzo yekutanga inoshandiswa mune imwe-piston brake system. Iyo piston inodzorwa neakakosha sikururu yakarukwa mairi. Inotenderera, ichityairwa netambo uye simbi. Iyo piston inofamba ichitevedza shinda, ichipinda mukati, inodzvanya mapedhi achipokana nebhureki disc.

Iyo cam mechanism iri nyore, ine pusher inoshanda papiston. Panguva imwecheteyo, cam ine hukama hwakasimba nerever (zvakare tambo). Iyo pushrod inofamba pamwe chete nepiston sezvo cam inotenderera. Iyo dhiramu michina inoshandiswa mune akawanda-piston masisitimu.

Maitiro ekushanda nemazvo

Pakarepo mushure mekupinda mumotokari, zvakakosha kutarisa nzvimbo ye handbrake lever. Iwe unofanirwawo kutarisa iyo isati yatanga chero ipi zvayo, haugoni kukwira handbrake, sezvo izvi zvichiita kuti injini iwedzere uye kukurumidza kupera kwezvinhu zvebrake system (madhisiki, mapedhi).

Kana iri yekuisa motokari pahandbrake mumwaka wechando, nyanzvi hadzikurudziri kuita izvi, sezvo izvi zvinogona kutungamirira kukuvhara mavhiri uye kusakwanisa kufamba. Sinou yakanyunguduka, tsvina inonamatira kumavhiri inogona kutonhora usiku, mapedhi anotonhora kumadhisiki kana chigubhu. Kana ukashandisa simba, unogona kukuvadza hurongwa, unoda kudziya mavhiri nemhepo, mvura inopisa kana kunyatsoita ne blowtorch.

Mumotokari dzine otomatiki, mabhureki ekupaka anofanirawo kushandiswa, kunyangwe kuvepo kweiyo "yekupaka" mode mubhokisi. Izvi zvinoderedza mutoro pane shaft yekuvhara michina, uye zvakare ichave nechokwadi chekuti mota inobatwa zvakasimba munzvimbo, dzimwe nguva munzvimbo ine shoma iwe unogona netsaona kupinda mumotokari yakavakidzana.

Summary

Iyo braking system, uye kunyanya iyo yekumisa mabhureki, inoita basa rakakosha uye ndechimwe chezvinhu zvakakosha zvemotokari. Izvo zvinodikanwa kuchengetedza zvese zvakarongeka, izvi zvichawedzera kuchengetedzwa kwekushanda kwemotokari yako, kuderedza njodzi yetsaona. Iyo yekumisa mabhureki system inofanirwa kuongororwa uye kushumirwa nguva nenguva, semamwe masisitimu akakosha.
