Uyini Umsebenzi Wephinikhodi Ye-Piston Ku-Piston?

2021-12-24

Umsebenzi wephinikhodi ye-piston ukuxhuma i-piston kanye nesiphetho esincane senduku yokuxhuma, futhi udlulise amandla phakathi kwepiston nenduku yokuxhuma.

Iphinikhodi ye-piston inomthwalo wokushaqeka ngezikhathi ezithile, futhi iyazishintsha, futhi isebenza ngaphansi kwezimo ezingezinhle zokugcoba. Ngakho-ke, iphinikhodi ye-piston iyadingeka ukuze ibe namandla anele nokuqina, ukuqina okuhle kwendawo, ukumelana nokugqokwa okuhle, nesisindo esincane. Izikhonkwane ze-piston ngokuvamile zenziwe ngamasilinda angenalutho, enziwe ngensimbi enekhabhoni ephansi kanye nensimbi ene-carbon alloy. Indawo yangaphandle i-carburized futhi icinywe ukuze kwandiswe ubulukhuni. Ngemva kokuphothula, ipholishwa ukuze ibe nokunemba kobukhulu obuphezulu kanye nokuqedwa kwendawo.

Isakhiwo esiyisisekelo sephinikhodi ye-piston ingumzimba we-tubular owugqinsi, futhi amanye anezakhiwo eziguquguqukayo ze-cross-section ngokusho kwezidingo zamandla alinganayo.
Kunezindlela ezimbili zokuxhuma iphinikhodi ye-piston emgodini wesihlalo sephinikhodi kanye nenduku yokuxhuma imbobo encane yokuphela kwesihlahla: ukuxhumana okugcwele okuntantayo kanye nokuxhumana okulinganayo okuntantayo.

Uxhumano oluntanta ngokugcwele lusho ukuthi uma injini isezingeni lokushisa elijwayelekile lokusebenza, iphinikhodi yepiston ingazungeza ngokukhululekile embotsheni yesihlalo sephini lephini lokuxhuma imbobo encane yomkhono wekhanda. Njengoba kuboniswe emfanekisweni, ngoxhumo olugcwele ukuntanta, iphinikhodi ye-piston ingakwazi ukumelana nomthwalo omkhulu womthelela, igqoke ngokulinganayo, futhi ibe nempilo ende yesevisi, kodwa inqubo yokuhlanganisa iyinkimbinkimbi kakhulu. Lapho uhlanganisa i-aluminium alloy piston kanye nephinikhodi, i-piston kufanele ishiswe emanzini noma emafutheni ezingeni lokushisa elingu-70-90℃ ukuze kunwetshwe imbobo yesihlalo sephinikhodi ngaphambi kokufaka iphinikhodi. Ukuze uvimbele ukujikeleza kwe-axial yephinikhodi ye-piston, izindandatho ze-snap nazo zifakwe kuzo zombili iziphetho zesihlalo sephini.

Uxhumano oluntanta kancane lusho ukuthi indawo eyodwa igxilile phakathi kwephinikhodi yephinikhodi nembobo yesihlalo sephini le-piston kanye nembobo yokuxhuma yokuxhuma imbobo encane yokugcina. Iphinikhodi evamile ye-piston igxilwe ekugcineni kwenduku encane yokuxhuma.Izingqimba ezibonisiwe nazo zihlanganiswe nephinikhodi ye-piston kanye nokuphela okuncane kwenduku yokuxhuma ngokufaka ukuphazamiseka. Njengoba kungekho ukunyakaza okuhlobene phakathi kwephinikhodi ye-piston kanye nenduku yokuxhuma, asikho isidingo sendandatho ye-snap ukukhawulela indawo ye-axial yephinikhodi ye-piston, okungukuthi, iphinikhodi ye-piston entantayo encane ayinayo indandatho ye-snap, futhi lapho. akukho bushing ekugcineni okuncane kwenduku yokuxhuma. Iphinikhodi ye-semi-floating piston inganciphisa umsindo wenjini futhi iqede izingozi ezingaba khona ezidalwa yi-snap ring. Isetshenziswa kakhulu ezinjinini ezilula ezinesivinini esiphezulu, njengeCherokee neCheetah, njll. izimoto zisebenzisa leli fomu.
