Ukukhupha amandla (i-PTO) sisixhobo somatshini esihambisa i-injini okanye amandla ombane ukusuka kwizixhobo zoshishino ukuya kwizicelo ezahlukeneyo. PTOs ziqhele ukusetyenziswa kwiilori zorhwebo ukuthutha iimpahla, imathiriyeli ekrwada, kunye neemveliso ezigqityiweyo. Badlala indima ebalulekileyo ekuqinisekiseni ukuba ezi lori zihamba kakuhle kumlinganiselo omkhulu.

Amandla kunye nokuSebenza kweeNjini zeelori zoRhwebo
Iinjini zelori ezintsha zorhwebo zixhotyiswe ngamandla aphezulu, zibonelela ngobuchule bokusebenza bamandla obuphezulu njenge-46% kunye nokusebenza okuthembekileyo. Ngokuzenzekelayo kunye nokuqhubela phambili kokufunda koomatshini, ezi njini zinokuphucula ukusebenza kakuhle kwamafutha kuyo nayiphi na imeko yendlela okanye kumhlaba. Utyalo-mali kwiinjini zelori zamva nje zivelisa imbuyekezo ephezulu, njengoko zenzelwe ukwandisa ukusebenza ngelixa zihlisa iindleko ezinxulumene nokusetyenziswa kwamafutha.
Zisebenza njani ii-PTOs
Ii-PTO ziqhagamshelwe kwi-crankshaft ye-injini yelori kunye nokudlulisa amandla e-injini nge-shaft yokuqhuba ukuya kwizinto eziqhotyoshelweyo. Ii-PTO zisebenzisa i-injini okanye amandla etrektara ukuguqula amandla ajikelezayo abe ngamandla okwenziwa ngolwelo olwenziwa ngamanzi, anokuthi ke asetyenziswe ukuqhuba amacandelo ancedisayo afana neempompo, izicinezeli, nezitshizi. Ezi nkqubo ziqhagamshelana neenjini zesithuthi nge-crankshaft kwaye zivulwe ngamalever okanye iswitshi.
Iinzuzo zoQhagamshelwano lwePTO kwiNjini yeLori
Uxhulumaniso oluthembekileyo phakathi kwe-PTO kunye ne-injini yelori ibonelela ngeenzuzo ezininzi, kubandakanywa nokusebenza lula, amanqanaba engxolo ancitshisiweyo, ukusebenza okuthembekileyo kokuchasana nokungcangcazela, ukuhanjiswa kwamandla okusebenzayo, kunye nokusebenza kakuhle kwamafutha kunye nokonga imali.
Iintlobo zeeNkqubo zePTO
Iinkqubo ezininzi zePTO ziyafumaneka, nganye ibonelela ngeempawu ezizodwa kunye neenzuzo. Ezinye zezi ntlobo ziquka:
- Ukwahlula ishaft: Olu hlobo lwenkqubo ye-PTO lusebenzisa i-gearbox yesibini eqhagamshelwe yi-shaft ephothiweyo, evumela umqhubi ukuba asebenzise amandla ngokufanelekileyo nakweyiphi na i-angle kwaye abandakanye okanye akhuphe i-PTO. Ilungele izicelo ezininzi, ngakumbi xa uthethathethwano olukhawulezayo nolwenziwa rhoqo okanye ukungabandakanywa kwe-PTO kuyimfuneko.
- I-shaft yokwahlula kwesandwich: Olu hlobo lweshafti lubekwe phakathi kothumelo kunye ne-injini kwaye lunokususwa ngokulula nakweliphina icala ngokukhupha iibholiti nje ezimbalwa. Ngobuchule bayo obuthembekileyo kunye nokungaguquguqukiyo bokudlulisa amandla, iSandwich Split Shaft ibe yinkqubo eqhelekileyo yePTO.
- Ngqo ngqo: Le nkqubo ivumela ukuhanjiswa ukuphambukisa amandla e-injini ukusuka kwi-motor ephantsi ukuya kwisicelo sangaphandle. Ivumela ukuyila okudibeneyo, ukudibanisa okulula kunye nenkonzo, iinxalenye ezincitshisiweyo kunye neendleko zabasebenzi, ukufikelela lula kokugcinwa kwe-injini, kunye nokuchithwa okusebenzayo kwe-clutch.
Ukusetyenziswa kweeYunithi zePTO kwiilori zoRhwebo
Iiyunithi ze-PTO ziqhele ukusetyenziswa kwiilori zorhwebo ukunika amandla inkqubo yokuvuthela, ukuphakamisa ibhedi yelori yokulahla, ukusebenzisa iwintshi itraki yokutsala, ukuqhuba i-compactor yokulahla inkunkuma yelori yenkunkuma, kunye nokuqhuba umatshini wokukhupha amanzi. Xa ukhetha i-PTO echanekileyo kwiimfuno ezithile, kubalulekile ukuqwalasela uhlobo lwesicelo, inani lezinto ezifunekayo, ubungakanani bomthwalo owenziweyo, naziphi na iimfuno ezikhethekileyo, kunye neemfuno zetorque yenkqubo.
isiphelo
Ii-PTO zibalulekile ekuqinisekiseni ukuba iilori zorhwebo zihamba kakuhle nangempumelelo. Ukuqonda iintlobo zeenkqubo ze-PTO ezikhoyo kunye nezicelo zazo kunokunceda ukukhetha i-PTO efanelekileyo kwiimfuno ezithile.
