Bezvtykovye pistons "Priora": tsim thiab cov yam ntxwv

Tus tswv ntawm "Lada Priora" tsheb feem ntau tau txais mus rau hauv cov teeb meem. Tawg sij hawm siv ua rau yus tu siab yuav tshwm. Qhov no yog hais tias lub pistons, uas lub chaw tsim tshuaj paus teev lub Hoobkas thaum lub engine yog tuaj txoos ua ke, muaj tsis txaus zauv tob. Cov kuaj raug xa mus rau raws li minders counterbore. Qhov no yog qhov ua rau ntawm kev puas tsuaj. Tsav kho tom qab xws li ib tug kev huam yuaj yuav raug nqi lub tswv tsheb yog kim heev. Pheej yig dua los hloov neeg ua hauj lwm nyob rau hauv lub thiaj li hu ua bezvtykovye pistons rau "xub".

Physics ua hauj lwm pistons, load

Qhov no lub caij no yog tsim los hloov lub zog los ntawm cov tawg ntawm roj nyob rau hauv ib tug reciprocating tsab ntawv tsa suab thiab kis rau lawv mus rau lub crankshaft. Thaum lub gases tom qab tawg nthuav, tus piston thiab cov hauj lwm nto yog txhua yam thiab thermal los. Nthuav dav yog muaj high-siv load. Qhov siab tshaj plaws tau siab nyob rau hauv lub "xub" cav yuav mus txog li rau 65-80 bar. Nws yog suab ib ob peb tonnes. Nyob rau hauv lub lag luam, lub pistons yuav ua tau tseg leeb nws txav mus rau 100 km / h los yog ntau tshaj. Tsis tas li ntawd, lawv lub zog yuav tsum tub ceevxwm mus rau ze li xoom ntawm ib zaus ntawm 200 Hz 6000 Rev. / min. Thaum nyob rau hauv lub thoob exploding huab cua thiab roj sib tov, qhov kub thiab txias sab hauv tsev yuav mus txog 1800-2600 degrees. Nyob rau hauv xws kub los yog txo lub dag lub zog yam ntxwv. Muaj thermal txhawj xeeb vim ceev kub hloov. Qhov no tib voltage yog tsim nyog los ntxiv lub siab ntawm lub combustion khoom thiab tus inertia thaum lub sij hawm acceleration thiab deceleration nyob rau high school frequencies.

Hais txog cov neeg ua hauj qauv ntawm cov pistons

Nyob rau hauv thiaj li yuav ua hauj lwm nyob rau hauv xws tej yam kev mob, qhov khoom yuav tsum, kom deb li deb li sai tau, ib qho yooj yim. Ib tug cov ntaub ntawv uas - resistant rau koj hnav.

Tsis tas li ntawd, lub combustion khoom yuav tsum tsis txhob txeem mus rau hauv lub crankcase. Lub piston muaj ib tug chim lawm, cov neeg kawm ntawv ntawm cov cua kub ntawm cov ua hauj lwm ib feem thiab nws daim tiab yog ib tug loj sib txawv. Qhov no ua rau nws tau mus ntsib tag nrho cov uas yuav tsum tau. Pab kom txawm peem tau deformation ntawm lub tiab nyob rau hauv tus txheej txheem, lub piston tau "protivoellipsom". Ib tug loj ib feem yog nruj me ntsis perpendicular mus rau lub axis ntawm lub bore axis rau mounting ib tug ntiv tes.

Piston taub hau los yog nws lub qhov muaj xws li ib tug hauv qab. Muaj kuj yog ib tug tshwj xeeb zawj rau mounting cov O-rings. Mus rau sab sauv feem yuav tiv uas muaj loads ntawm lub ntau lawm theem nws yog coated nrog ib tug tshwj xeeb txheej ntawm cov kev tiv thaiv txheej. Grooves rau mounting rings yog ua kom muaj ib tug me me lub. Qhov no saib kuas qhov chaw ntawm lub txheej ntug ntawm lub nplhaib yog siab tshaj lub puab. Qhov no tiv thaiv cov inclination ntawm tus ntoo khaub lig-seem ntawm lub zawj down thaum lub sij hawm kev lag luam nyob rau high school kub loads. Yuav kom muab ib tug zoo dua piston zawv zawg thoob plaws lub chaw ua hauj lwm nto yog kho nrog tshwj xeeb coatings. Yuav kom zoo dua ib feem burnished, xws coatings yog siv, uas yog hnav thaum lub sij hawm khiav. Qhov no tin plating los yog phosphate. Ntaub ntawv, ris hauv qab, nyob twj ywm rau ntawm qhov chaw lub caij ntawm lub lag luam. Cov tiab tiav los ntawm txoj kev cutters. Qhov no yog ua kom tau ib tug micro-relief. Vim rau qhov no, cov roj yog muab khaws cia tseg zoo dua rau lub workpiece nto, yog li kom txhob muaj kev sib txhuam.

Txawv nyob rau hauv lub tsim ntawm "kev ruaj ntseg" pistons "Priora"

Yog li ntawd bezvtykovye pistons rau lub "qhov muaj feem thib" ntawm cov neeg ua hauj tsis txawv. Qhov no yog ua tau ib tug tib yam ntawm ib tug txheej txheem piston xyaw los ntawm "AvtoVAZ". Tab sis nyob rau sab saum toj ntawm cov tsoos daim iav muaj - es tsis txhob muaj sib sib zog nqus zauv. Qhov no ua rau nws tau mus ua ib lub rooj sib tham nrog cov qub thiab cov ntsiab lus ntawm lub sij hawm, thiab lub pistons lawv tus kheej. Qhov ntev thiab tag nrho lwm yam tsis yog tag nrho raws li tus yam ntxwv ntawm tus txheem qhov chaw.

Yog vim li cas teem nezavodskie pistons?

Nyob rau txhua lub tsheb ib lub zuj zus. Yog hais tias tag nrho ua raws li cov kev cai ntawm lub chaw tsim tshuaj paus ntawm lub cav txij nkawm, los tsim pom zoo los yog tsawg kawg zoo spare qhov chaw thiab consumables, ces lub tsheb yuav tsum muaj ib tug ntev thiab zoo, thiab tag nrho cov mechanisms thiab units yuav ua hauj lwm nyob rau hauv nws tej hom.
