Tsheb nres nruas: tshem tawm thiab hloov

Muaj ntau niaj hnub tsheb yog nruab nrog disc brakes pem hauv ntej thiab nram qab lub. Tab sis nws yog tseem tseem ua machines, uas siv lub rear nres drums. Qhov no mechanism yog siv nyob rau hauv lub tsheb lag luam rau ntau tshaj ib tiam. Raws li nrog rau ntau ntau lwm yam hais, xws braking system yuav hnav cia, thiab ces nws yog tsim nyog los muab rho thiab hloov cov qhov chaw.

tsim

Nruas nres Tsheb nruab nrab yog ob peb qhov chaw. Qhov no yog ib yam nruas thiab nres pawm no ntau npau. Thaum lub sij hawm braking kawg xuas tiv thaiv cov hauv nplaim lub hollow nruas. Nyob rau hauv thiaj li yuav ncoo yuav tsiv mus nyob rau tsim muaj tshwj xeeb springs. Lawv compressed los yog decompressed, nyob ntawm seb tus neeg tsav tsheb depresses tus brake los yog tawm nws. Thaum lub sij hawm kev lag luam ncoo sau raws nkaus Ii nres lub tog raj kheej - nws pa ua hauj lwm kua presses lub ncoo mus rau qhov chaw ntawm lub nruas. Cov thooj voos kheej kheej yuav tsum tau ob peb. Tag nrho cov mechanism yog mounted rau ib tug stamped nres board.

Tsheb nruas nres tej zaum yuav muaj ib tug txawv tsim - kab xev. Ntawm no braking yog nqa tawm los ntawm ib tug saj zawg zog hlau sawb uas yog tensioned thiab compresses lub nruas. Los ntawm no system nyob rau hauv lub tsheb lag luam tau ntev tau tso tseg.

Nruas nres: pab daws teeb meem

Ib tug ntawm lub ntsiab zoo ntawm cov mechanisms yog hais tias lawv muaj nrees kaw rau tej ib puag ncig influences. Qhov no braking system yog zoo tagnrho rau siv nyob rau hauv hnyav los yog huab tej yam kev mob.

Cov ntaub qhwv to yog yuav luag tsis muaj plua tshauv thiab dej, uas zoo heev tsub kom lub neej ntawm qhov chaw. Tsis tas li ntawd, thaum lub sij hawm braking, xws li ib tug system generates tsawg tshav kub, qhov no ua rau nws tau siv cheaper pib theem ntawm cov kua nrog ib tug tsawg kub point.
