Tej teeb meem ntawm Nres Friction Phaj (3)
Vim li cas braking hysteresis tshwm sim?
Cov laj thawj uas tshwm sim rau qhov tshwm sim ntawm tus nres hysteresis yog: tsis ua haujlwm ntawm lub nres rov qab lub caij nplooj ntoos hlav, kev tshem tawm tsis raug ntawm cov phaj txhuam thiab cov nres nres lossis qhov sib dhos nruj heev, tsis tsim nyog thermal expansion kev ua tau zoo ntawm cov phaj sib txhuam, thiab kev rov qab tsis zoo ntawm cov nres nres nres. .
Vim li cas thiaj muaj pa taws thaum nres?
Cov phaj sib txhuam muaj li ntawm 20 feem pua ntawm cov organic teeb meem, uas yuav decompose thiab emission pa luam yeeb thaum kub siab heev, thiab ib txheej ntawm oily khoom yuav tsim nyob rau ntawm qhov chaw ntawm lub phaj txhuam, uas yuav cuam tshuam rau lub braking nyhuv. Cov laj thawj uas tshwm sim rau qhov tshwm sim no yog: nquag nres thaum nce toj, ua rau qhov kub thiab txias heev thiab haus luam yeeb; cov organic cov ntsiab lus nyob rau hauv cov mis ntawm kev sib txhuam phaj yog tsis tsim nyog thiab tshaj tus qauv.
Vim li cas lub phaj rov qab ntawm qhov sib txhuam phaj poob?
Muaj ob qhov xwm txheej rau lub phaj rov qab ntawm cov phaj txhuam kom poob. Ib qho yog tias qhov tawg tshwm sim ntawm lub phaj nraub qaum thiab cov khoom sib txhuam; Lwm qhov yog tias cov khoom sib txhuam nws tus kheej tawg. Cov laj thawj yog vim li cas: kev kho tsis zoo ua ntej ntawm lub phaj nraub qaum, tsis muaj kev ruaj ntseg ntawm cov khoom sib txhuam, cov txheej txheem tsis tsim nyog, cov nplaum tsis zoo, kev siv kub ntau, kev teeb tsa tsis raug, cuam tshuam thiab khob.
Dab tsi yog qhov ua haujlwm ntawm cov grooves hauv cov pawm nres?
Kev ua haujlwm ntawm cov grooves hauv cov phaj sib txhuam yog tso tawm cov roj, txo cov suab nrov thiab hloov lub ntuj zaus ntawm cov khoom, tshem tawm cov khib nyiab pov tseg, thiab txhim kho cov adhesion ntawm cov khoom sib txhuam thiab cov phaj rov qab.
