Literaka le lisebelisoa tse fapaneng tse boima li sebelisa li-braking system tse laoloang ke brake valve.Bala tsohle ka li-valve tsa brake, mefuta ea tsona, moralo le ts'ebetso, hammoho le khetho e nepahetseng le phetoho ea yuniti ena sehloohong sena.
Belofo ea brake ke eng?
Brake valve - karolo ea taolo ea tsamaiso ea brake ea likoloi tse nang le koloi ea pneumatic;valve ea pneumatic e tsamaisoang ke pedal ea brake, e fanang ka moea o hatelitsoeng ho li-actuator (likamore tsa brake) le likarolo tse ling tsa tsamaiso nakong ea braking.
Literakeng le likoloing tse ling tse nang le mabili, litsamaiso tsa braking tse tsamaisoang ke moea li sebelisoa haholo, tse phahametseng ts'ebetso le ts'epahalo ho sistimi ea hydraulic.Taolo ea lihlopha tsa tsamaiso e etsoa ka lisebelisoa tse khethehileng - li-valve le li-valve.E 'ngoe ea likarolo tsa bohlokoa tsamaisong ea pneumatic e bapaloa ke valve ea brake, eo ka eona li-brake tsa mabili li laoloang.
Brake valve e etsa mesebetsi e mengata:
● Ho etsa bonnete ba phepelo ea moea o hatelitsoeng ka har'a likamore tsa mariki ha ho hlokahala ho etsa braking;
● Ho fana ka "brake pedal feeling" (kamano e leka-lekaneng pakeng tsa tekanyo ea braking ea koloi le matla holim'a pedal, e leng se lumellang mokhanni hore a hlahlobe ka nepo mokhoa oa ho koala le ho lokisa mokhoa ona);
● Li-valve tsa likarolo tse peli - ho netefatsa ts'ebetso e tloaelehileng ea potoloho e le 'ngoe ha ho e-na le ho lutla ha moea ho e' ngoe.
Ke ka thuso ea valve ea brake hore tsamaiso ea brake e laoloa ka mekhoa eohle ea ho khanna, kahoo sesebelisoa sena ke sa bohlokoa haholo bakeng sa ts'ebetso e tloaelehileng ea koloi.Crane e fosahetseng e tlameha ho lokisoa kapa ho nkeloa sebaka, 'me bakeng sa khetho ea eona e nepahetseng ho hlokahala ho utloisisa mefuta e teng, moralo le molao-motheo oa ts'ebetso ea lisebelisoa tsena.
Mefuta, moralo le molao-motheo oa ts'ebetso ea valve ea brake
Li-valve tsa Brake tse sebelisoang likoloing li arotsoe ka lihlopha tse peli tse kholo ho latela palo ea likarolo tsa taolo:
- Karolo e le 'ngoe;
- Likarolo tse peli.
Brake valve e nang le pedal
Li-cranes tse nang le karolo e le 'ngoe li kentsoe likoloing tse sa sebetsoeng ka litereilara tse nang le mariki a moea.Ke hore, crane ena e fana ka taolo feela ea tsamaiso ea braking ea koloi.Li-cranes tse nang le likarolo tse peli li sebelisoa likoloing tse tsamaisoang ka litereilara / li-semi-trailer tse nang le sistimi ea mariki a moea.Crane e joalo e fana ka taolo ea mariki a terekere le tereilara ho tloha pedal e le 'ngoe.
Ka lehlakoreng le leng, li-cranes tsa likarolo tse peli li arotsoe ka mefuta e 'meli ho latela sebaka le mokhoa oa ho laola likarolo:
● Ka taolo ea lever ea karolo e 'ngoe le e' ngoe - koloi e etsoa ka lisebelisoa tse peli tse nang le li-hinged tse nang le koloi e le 'ngoe e nang le mochine o tsoang ho brake pedal, mochine ona likarolo li ikemela (ha li kopane);
● Ka molamu o tloaelehileng bakeng sa likarolo tse peli - koloi ea likarolo tse peli e etsoa ke molamu o le mong, o tsamaisoang ke pedal ea brake, sesebelisoa sena karolo e le 'ngoe e ka laola ts'ebetso ea bobeli.
Moralo le molao-motheo oa ts'ebetso ea li-valve tsohle li ts'oana, 'me liphapang li teng ho lintlha tse hlalositsoeng ka tlase.
Karolo ea crane e na le likarolo tse 'maloa tsa mantlha: actuator, sesebelisoa sa ho latedisa, li-valve tsa ho kenya le ho tsoa.Likarolo tsohle li behiloe nyeoeng e tloaelehileng, e arotsoe likarolo tse peli: karolong e le 'ngoe, ho buisana le sepakapaka, ho na le koloi le sesebelisoa sa ho latela;Karolong ea bobeli, e kopantsoeng ke li-fittings ho ea amohelang (li-receivers) le mohala oa kamore ea brake, li-valve tsa ho kenya le ho ntša metsi tse kentsoeng molamung o le mong li teng.Likarolo tsa 'mele li arotsoe ke diaphragm (rabara kapa rabara), e leng karolo ea sesebelisoa sa ho latela.The actuator ke sistimi ea levers kapa push lever e hoketsoeng ho brake pedal ka molamu.
Sesebelisoa sa ho latella se hokahane ka kotloloho le koloi ea li-valve le brake pedal, e na le molamu le seliba (kapa piston ea sebopeho se itseng), pheletso ea molamu e ka holim'a setulo se tsamaeang sa valve ea ho tima - a tube e kentsoeng ka khalase, eo le eona e leng khahlanong le diaphragm.Ho na le sekoti ka khalase e fanang ka puisano pakeng tsa halofo ea bobeli ea 'mele le sepakapaka.Li-valve tsa ho kenya le ho qeta li entsoe ka mokhoa oa li-cones tsa rabara kapa mehele e lutseng khahlanong le litulo tsa bona.
Brake valve e sebetsa ka mokhoa o bonolo.Ha pedal e lokolloa, li-valve li hlophisitsoe ka tsela eo mohala oa ho amohela o koetsoe, 'me mohala oa kamore ea brake o buisana le sepakapaka - sebakeng sena tsamaiso ea brake ha e sebetse.Ha "brake pedal" e hatelloa, sesebelisoa sa ho latela se tiisa hore valve ea ho ntša metsi e koala 'me valve ea ho kenya e buleha ka nako e le' ngoe, ha sebaka sa valve se nang le li-valve se tlosoa sepakapakeng.Boemong bona, moea o hatelitsoeng o tsoang ho ba amohelang o phalla ka li-valve ho ea likamoreng tsa brake - braking e etsoa.Haeba mokhanni a emisa pedal sebakeng leha e le sefe, khatello ea 'mele oa crane, e khaotsoeng sepakapakeng, e eketseha ka potlako, mohloli oa mochine oa ho latela o hatelloa, setulo sa valve ea ho tima sea phahama, e leng se lebisang ho koaleheng ha ho kenngoa. valve - moea o tsoang ho ba amohelang o khaotsa ho phalla ho ea likamoreng tsa brake.Leha ho le joalo, valve ea ho qeta ha e bulehe, kahoo khatello ea moleng oa kamore ea brake ha e fokotsehe, ka lebaka la hore braking e etsoa ka matla a le mong kapa a mang.Ka ho hatelloa ho eketsehileng ha pedal, li-valve li bula hape 'me moea o kena ka likamoreng - braking e matla haholoanyane.Sena se tiisa tekano ea boiteko bo sebelisoang ho pedal le matla a braking, 'me, ka lebaka leo, e baka "maikutlo a pedal".
Moralo le ts'ebetso ea crane ea KAMAZ ea likarolo tse peli
Ha pedal e lokolloa, sesebelisoa sa ho latela se tlosoa ho li-valve, ka lebaka leo valve ea ho kenya e koala tlas'a ts'ebetso ea selemo, 'me valve ea ho qeta e bulehile - moea o hatelitsoeng o tsoang moeling oa kamore ea brake o ea sepakapakeng, ho thibela moea. etsahala.Ha o tobetsa pedal hape, lits'ebetso tsohle li phetoa.
Ho na le meralo e meng ea li-valve tsa brake, ho kenyelletsa le valve e le 'ngoe feela e nkang sebaka sa ho kenya le ho ntša metsi, empa molao-motheo oa ts'ebetso ea lisebelisoa tse joalo o tšoana le o hlalositsoeng ka holimo.Likarolong tse ling tsa likarolo tse peli, karolo e le 'ngoe (e ka holimo) e ka sebetsa e le sesebelisoa sa ho latela karolo e ka tlaase, lisebelisoa tse joalo li na le mekhoa e eketsehileng ea ho netefatsa hore ho sebetsa ha karolo e ka tlaase ho se na khatello karolong e ka holimo.
Li-valve tsa Brake, ho sa tsotelehe moralo le ts'ebetso, li ka ba le likarolo tse ngata tse thusang:
● Pneumatic brake light switch ke sesebelisoa sa electro-pneumatic switching se buisanang le valve ea valve, eo, ha khatello e phahama (ke hore, ha e qhoma) e khantša lebone la brake ea koloi;
● Muffler ("fungus") ke sesebelisoa se fokotsang molumo oa lerata oa moea o tsoang sepakapakeng ha koloi e lokolloa;
