Ukumuncwa ukushaqeka kwezimoto
Kusistimu yokumiswa, isici esinwebekayo siyandindizela ngenxa yomthelela. Ukuze uthuthukise ukunethezeka kokugibela kwemoto, i-shock absorber ifakwe ngokuhambisana ne-elastic element ekumisweni. Ukuze kuncishiswe ukudlidliza, isibambisi sokwethuka esisetshenziswa ohlelweni lokumiswa kwemoto sivame ukudonsa amanzi nge-hydraulic shock. Isimiso sayo sokusebenza siwukuthi lapho ukudlidliza phakathi kohlaka (noma umzimba) kanye ne-ekseli kwenzeka ukunyakaza okuhlobene, i-piston ku-shock absorber iyehla iye phezulu, Amafutha asemgodini obamba ukushaqeka ageleza ngokuphindaphindiwe esuka kwesinye imbobo ngokusebenzisa izimbotshana ezihlukene aye kwenye. umgodi.
Ngalesi sikhathi, ukungqubuzana phakathi kodonga lwembobo namafutha [1] kanye nokungqubuzana kwangaphakathi phakathi kwama-molecule kawoyela kwakha amandla okudambisa ukudlidliza, ukuze amandla okudlidliza kwemoto aguqulwe abe amandla okushisa amafutha, adonswa futhi akhishwe. emkhathini nge-shock absorber. Uma ingxenye yesiteshi sikawoyela nezinye izici zihlala zingashintshile, amandla okudambisa akhuphuka noma ehle ngesivinini esihlobene sokunyakaza phakathi kohlaka kanye ne-ekseli (noma isondo), futhi ahlobene ne-viscosity kawoyela.
I-shock absorber kanye ne-elastic element yenza umsebenzi wokunciphisa umthelela nokudlidliza. Uma amandla okuthambisa makhulu kakhulu, ukuqina kokumiswa kuzowohloka, futhi ngisho nezingxenye zokuxhuma ze-shock absorber zizolimala. Ngenxa yokungqubuzana phakathi kwe-elastic element kanye ne-shock absorber.
(1) Ngesikhathi sokuminyanisa i-stroke (i-asili nefreyimu kusondelene), amandla okudambisa okomunca ukushaqeka mancane, ukuze anikeze ukudlala okugcwele kumphumela wokunwebeka wento enwebekayo futhi kuncishiswe umthelela. Ngalesi sikhathi, i-elastic element idlala indima enkulu.
(2) Phakathi ne-stroke yesandiso sokumiswa (i-ekseli nohlaka kuqhelelene komunye nomunye), amandla athobisayo we-shock absorber kufanele abe mkhulu futhi amunce ukudlidliza ngokushesha.
(3) Uma isivinini esihlobene phakathi kwe-asi (noma isondo) kanye ne-ekseli sikhulu kakhulu, isidambisi manzi sidingeka ukuthi sikhulise ngokuzenzakalelayo ukugeleza koketshezi ukuze kugcinwe amandla okudambisa ngaphakathi komkhawulo othile, ukuze kugwenywe ukuthwala umthelela omningi.
I-cylindrical shock absorber isetshenziswa kakhulu ohlelweni lokumiswa kwezimoto, futhi ingadlala indima yokumunca ukushaqeka kukho kokubili ukuminyanisa nokunwetshwa kwe-stroke. Ibizwa ngokuthi i-bidirectional shock absorber. Kukhona nezinto ezintsha zokudonsa ukushaqeka, okuhlanganisa i-inflatable shock absorber kanye ne-resistance adjustable shock absorber.
