Yuav ua li cas yog PPC

Muaj coob tus neeg yuav txaus siab nyob rau hauv cov nqe lus nug ntawm yog dab tsi PPC? Yog li ntawd, yog koj hais lub qhuav lus, qhov gearbox yog tsim los hloov lub torque, uas yog kis tau mus rau tus tsav log ntawm lub crankshaft. Thiab yog hais tias koj saib los ntawm cov foundations hauv ib newbie rau lo lus nug ntawm yog dab tsi ib tug PPC, thiab dab tsi hloov iav, ces muaj yog ib tug ntau ntawm complexities. Iav shifting yog ib tug yuav tsum tau hais tias tau arisen vim lub fact tias cov torque yam ntxwv ntawm lub hauv combustion engine txawv sis tsis ncaj. Koj yuav piv nrog combustion engine nrog ib tug hluav taws xob motor.

Lub ntsiab sib txawv nruab nrab ntawm lawv nrog peb taw tes ntawm view yog cov traction, uas yog, nyob rau hauv kev sib raug zoo mus rau lub xov tooj ntawm lub hwj chim hloov ceev torque. Lub cev muaj zog muaj ib tug yawm torque thaum uas tsis muaj speeds. Index ntog li unwinding. Qhov no cov yam ntxwv yog ntau paaj rau tag nrho tshuab thaum lub sij hawm pib thiab tom ntej dispersal, thaum ib tug loj quab yuam yog tsim nyog los mus kov yeej lub inertia, nws yog qhov zoo tshaj plaws lub sij hawm kom muaj tus loj tshaj tau torque. Uniform tsab ntawv tsa suab kom rau tus txij nkawm ntawm ib tug ntau me me torque. Thaum twg ceev lub hwj chim ntawm lub fais tsav tej zaum yuav nyob twj ywm suab tshaj plaws, thiab siv nyob rau hauv tag nrho cov kev khiav hauj lwm yuav luag nkaus, i.e. mus rau txoj kev mob nws yog haum txig.

Yog hais tias peb tham txog cov internal combustion engine, nws yog tag nrho cov heev txawv, thaum uas tsis muaj speeds nws muaj peev xwm significantly txo, thiab cov torque nqi hloov me ntsis nyob rau hauv lub cheeb tsam ntawm kev kawm zauv. Traction yam ntxwv ntawm xws li ib engine yog tsis yog txawm fee. Txawm li cas los, lwm yam kev ntsuas ntawm lub hwj chim nroj tsuag nrog rau ib tug zoo xws li cov cav kom meej meej superior rau lub electric tsav. Txij li thaum lub designers tau raug yuam kom muab nrog xws li tsis xws luag, lub tsheb twb nruab nrog ib phau ntawv kis tau tus mob los mus kov yeej lawv. Yog li ntawd, dab tsi yog PPC? Nws yog tsim los izmeniyat iav ratio, uas yog muaj nyob rau ntawm lub cav thiab lub ntsiab log.

Ntsuam xyuas cov teeb meem ntawm "PPC - dab tsi yog" nws yuav tsum tau hais tias qhov sib txawv muaj nuj nqis ntawm torque yuav tau los ntawm kev siv zog ntawm txawv ntau thiab tsawg. Yog hais tias koj tso ib nrab iav ntawm tus qhev thiab tus tswv, yuav hloov cov kev coj ntawm kev sib hloov ntawm lub tsav, uas muab rau peb qhov rov qab iav. Nws hloov tawm hais tias txhua txhua kis: tsis siv neeg, robotic, neeg kho tshuab variator los yog ua hauj lwm pab muab cov pom engine lag luam hom nyob rau hauv txawv tej yam kev mob los ntawm kev pauv qhov kev txiav txim ntawm lub iav ratio.

Tej kis tau tus mob yog tsawg dua thiab ntau dua theem. Los ntawm ib tug sawv pib, acceleration, ceev kom me tom ntej tsab ntawv tsa suab los yog nyob rau hauv txoj kev tab tom nrhiav rau lub feem ntau siab torque achievable ntawm medium-kev kub ceev, Txawm li cas los, nws tsis yog tsim nyog nyob rau hauv lub high-ceev txoj kev loj hlob. Lub zog nyob rau hauv no hom muab tus nqi qis tshaj rung nyob rau hauv lub gearbox, uas muaj ib tug me me iav ratio, uas txhais tau tias txawm nyob speeds siab ntawm lub cev muaj zog lub tsheb yuav txav mus maj mam.

Uniform tsab ntawv tsa suab thaum muaj kev kub ceev yuav ua tau tiav xwb nyob rau hauv cov ntaub ntawv ntawm siab zaus ntawm log kev sib hloov, thiab tseem thaum tswj lub cav ceev ntawm ib qho kev pom ntau yam. Qhov no yog tau ua tsaug rau lub siab lub zog, uas muaj tsawg dua iav ratios. Lub tsheb yuav tsum nyob rau ib tug zoo xws li cov ceev lub cev muaj zog tsav considerably sai kom txog rau thaum nws nce mus txog ib tug tshaj plaws ceev. Txawm li cas los, nyob rau hauv sab saum toj iav tsheb tsis tau tsiv mus thaum uas tsis muaj kev ceev, thiab tau txais ib txav rau, raws li nws yog tsis yuav tsum tau rau propulsion yog tsim torque thiab pog laus lub tsheb nws tus kheej. Yog li ntawd, koj yuav tsum tau tseeb hais tias xws li ib daim tshev point, thiab yog vim li cas nws yuav tsum tau nyob rau hauv lub tsheb.
