Ithini i-front brake caliper yemoto enama-brake pads
I-brake caliper iyingxenye ebalulekile ye-chassis braking yesistimu yokubhuleka. Umsebenzi wayo omkhulu ukuphusha ama-brake pads, nama-brake pads agudla isigubhu sebhuleki. Yehlisa isivinini semoto futhi uyimise. Ngemuva kokufakwa kwebhuleki, isilinda esiyinhloko sikhiqiza i-thrust ukuze icindezele uwoyela we-hydraulic kusilinda sesigqila. I-piston ngaphakathi kwesilinda sesigqila ingaphansi kwengcindezi ye-hydraulic futhi iqala ukunyakaza, iphusha ama-brake pads.
I-hydraulic brake yenziwe nge-master cylinder kanye ne-brake fluid reservoir. Ingxenye eyodwa yazo ixhunywe ku-pedal yebhuleki kanti enye ixhunywe kwipayipi likawoyela wamabhuleki. I-master cylinder yebhuleki ibamba i-brake fluid futhi ine-outlet kawoyela kanye nendawo yokufaka uwoyela.
I-air brake yakhiwe i-air compressor (evame ukwaziwa ngokuthi i-air fum), okungenani amathangi omoya amabili, iphampu eyodwa yamabhuleki ayinhloko, i-valve eyodwa ephuma ngokushesha esondweni langaphambili, kanye ne-valve yokudlulisa eyodwa esondweni elingemuva. Iqukethe ama-brake caliper amane, ama-adjuster amane, amakhamera amane, izicathulo zamabhuleki ayisishiyagalombili kanye nama-brake hub amane.
I-Hydraulic brake
Ibhuleki likawoyela lakhiwe nge-brake master cylinder (hydraulic brake pump) kanye ne-brake fluid tank.
Amaloli amakhulu asebenzisa amabhuleki omoya, kuyilapho izimoto ezincane ezivamile zisebenzisa amabhuleki kawoyela. Ngakho-ke, kokubili i-master brake pump kanye nama-brake caliper emoto amaphampu amabhuleki asebenza nge-hydraulic. Ama-brake caliper (amaphampu amabhuleki e-hydraulic) ayizingxenye ezibalulekile zesistimu yokubhuleka. Uma ubhuleka, uma unyathela ibhuleki pad, isilinda esiyinhloko sebhuleki siletha uketshezi lwamabhuleki ngamapayipi ku-brake caliper ngayinye. I-brake caliper inenduku yokuxhuma elawula izicathulo zamabhuleki noma ama-brake pads. Lapho ubhuleka, uketshezi lwebhuleki kushubhu lamabhuleki luphusha induku yokuxhuma ku-brake caliper, okubangela ukuba isicathulo sebhuleki sibambe i-flange esondweni ukuze limise isondo. Izidingo zobuchwepheshe ze-brake caliper yemoto ziphezulu kakhulu ngoba zithinta ngqo izimpilo zabantu.
Lapho ibhuleki lifakwa, indawo yokukhipha uphethiloli iyavuleka futhi i-fael inlet iyavaleka. Ngaphansi kwengcindezi yepiston emzimbeni wepompo, ipayipi likawoyela wamabhuleki liyampintshana liphume epayipini likawoyela bese ligeleza liye kwiphampu yesigqila sebhuleki ngalinye ukuze lenze umsebenzi wokubhuleka. Lapho ukhulula ibhuleki pad. Indawo kawoyela eyisilinda esiyinhloko izovala futhi indawo yokungena kawoyela izovuleka, ivumele uketshezi lwebhuleki ukuthi lugeleze luhlehle lusuka kusilinda sesigqila sebhuleki ngalinye luye kusilinda esikhulu futhi lubuyele esimweni salo sasekuqaleni.
Iloli
Ushayelwa iphampu yomoya enjinini, umoya ucindezelwa ube yigesi enomfutho ophezulu bese ugcinwa ethangini lomoya. Esinye sezamukeli zomoya singaxhunywa kusilinda esiyinhloko sebhuleki ngamapayipi. I-master brake cylinder ihlukaniswe ngamakamelo amabili omoya, elingenhla nelingaphansi. Igumbi lomoya eliphezulu lilawula amasondo angemuva, futhi igumbi lomoya eliphansi lilawula amasondo angaphambili. Lapho umshayeli enyathela ibhuleki, ithangi lomoya eliphezulu liyavuleka kuqala. Igesi enomfutho ophezulu ethangini lomoya idluliselwa ku-valve edluliswayo, iphushela ngaphandle ipiston yokulawula yevalvu edluliswayo. Ngalesi sikhathi, igesi kwelinye ithangi lomoya ingaxhunywa kuma-caliper amabhuleki angemuva ngevalvu edluliswayo. I-push rod ye-brake caliper iphushelwa phambili. Ngokulungisa ingemuva, i-CAM izungeziswa nge-engeli. I-CAM ine-eccentric. Ngenkathi ijikeleza, isakaza izicathulo zamabhuleki futhi ikhiqize ukungqubuzana nesigubhu sebhuleki ukuze kuzuzwe umphumela wokubhuleka.
Lapho ikamelo eliphezulu le-brake master cylinder livulwa, igumbi elingezansi nalo livulwa kanyekanye. I-high-pressure gas ingena kuvalvu ephuma ngokushesha bese ihanjiswa kuma-brake caliper amasondo amabili angaphambili. Okufanayo kuya emasondo angemuva.
Uma umshayeli ededela i-pedal yamabhuleki, ama-air chamber aphezulu naphansi ayavaleka, bese kuthi amapiston evalvu yokungena ngokushesha esondweni langaphambili kanye ne-relay valve esesondo elingemuva abuyele lapho ayekuyo ekuqaleni ngaphansi kwesenzo se-spring. Ama-brake caliper angaphambili nangemuva axhunywe emkhathini egumbini lomoya. I-push rod ibuyela endaweni yayo futhi ukubhuleka kuqediwe.
Ngokuvamile, amasondo angemuva aphuka kuqala futhi amasondo angaphambili kamuva. Lokhu kuyazuzisa ukuthi umshayeli alawule indlela.
