Bendix starter - ndichiyani? Chithunzi
Ndizovuta kwa munthu wosadziwa mawu agalimoto kuti amvetsetse tanthauzo la mayina ena. Wogawa, jeti, bendix, rocker, trunnion ndi zina zotero - muyenera kuvomereza, si ambiri omwe angamvetse zomwe zili pangozi. Kuphatikiza apo, zidule zitha kuwoneka m'mabuku: SHRUS, PTF, KSHKh, ZDT, mutu wa silinda. Komabe, kudziwa tanthauzo la mawu onsewa ndikofunikira osachepera kuti mugule gawo loyenera mu sitolo yamagalimoto.
Ngati muli ndi mavuto ndi choyambitsa, ndiye chimodzi mwa zifukwa zingakhale kuwonongeka kwa bendix. Chithunzicho ndi chodziwika bwino: mukuyesera kuyambitsa injini, mumatha kumva kuwonekera kwa retractor, ndiyeno phokoso lodziwika bwino - giya yothamanga kwambiri sikugwirizana ndi crankshaft flywheel korona. Chifukwa chake ndi nthawi yoti muwone momwe bendx ilili ndi magiya ake.
M'kabukhu la magawo, gawoli nthawi zambiri limatchedwa starter drive kapena overrunning clutch. Kwa anthu wamba, clutch iyi imatchedwanso bendix, polemekeza woyambitsa waku America yemwe adazipanga patent. Bendix imagwira ntchito yofunika kwambiri - ndi kudzera momwemo kuti kuzungulira kwa shaft yoyambira kumayendetsedwa ku crankshaft chifukwa cha khola loyendetsedwa ndi zida.
Talemba kale patsamba lathu la Vodi.su za momwe zimayambira pomwe choyambira chikuzungulira, koma galimotoyo sidzayamba.
Timakumbukiranso mfundo yogwiritsira ntchito poyambira:
- pompopompo kuchokera ku batire imaperekedwa kumayendedwe oyambira;
- tsinde la armature limayamba kuzungulira, pomwe clutch yopitilirapo ili;
- pali splines pamtengo, pambali pawo bend imasunthira ku flywheel;
- mano a bend gear mesh ndi mano a flywheel korona;
- pomwe flywheel imazungulira liwiro linalake, zida zoyambira zimachotsedwa ndipo bendix imabwereranso.
Ndiko kuti, monga tikuonera, pali mfundo ziwiri zofunika: kusuntha kwa kasinthasintha kuchokera ku nthiti ya armature kupita ku flywheel yoyambira, ndi kutsekedwa kwa zida za bendix pamene flywheel ikufika pa chiwerengero china cha kusintha pamphindi. Ngati kulumikizidwa sikunachitike, ndiye kuti choyambiracho chimangowotcha, chifukwa liwiro lalikulu la shaft ya armature ndi lotsika kwambiri kuposa liwiro lozungulira la crankshaft.
Ndiyeneranso kudziwa kuti zida zoyambira zimatha kuzungulira mbali imodzi.
Chida choyambira bendix
Zinthu zazikulu za drive ndi:
- khola loyendetsedwa ndi zida - limapereka chinkhoswe ndi flywheel;
- chojambula chotsogola - chomwe chili pamtunda woyambira ndikuzungulira nacho;
- buffer spring - imafewetsa nthawi yolumikizana ndi giya ndi korona wakuwulukira (nthawi zina clutch sichitika koyamba ndipo chifukwa cha kasupe uyu giya imabwerera ndikuyambiranso);
- odzigudubuza ndi akasupe othamanga - amalola kuti zida ziziyenda mbali imodzi yokha (ngati zodzigudubuza zichotsedwa, zida zimatsika injini ikayamba).
Nthawi zambiri, kuwonongeka kumachitika chifukwa cha kuwonongeka kwa mano a giya loyambira. Pankhaniyi, muyenera kuchotsa choyambira ndikusintha bendix, ngakhale m'masitolo ena mutha kupeza zida zokonzera zomwe zidazo zimagulitsidwa padera. Zikhale momwe zingakhalire, ndizovuta kukonza choyambira popanda kukonzekera bwino.
Pang'ono ndi pang'ono, kasupe wa buffer amakhala wofooka. Ndikosavuta kuwonetsetsa kuti yamasulidwa - mukatembenuza kiyi poyatsira, mutha kumva phokoso. Injini idzayamba, koma kusokonezeka kwa mano koteroko kumapangitsa kuti giya la bendix liwonongeke mwachangu komanso mphete ya flywheel (ndipo kukonza kwake kudzawononga ndalama zambiri kuposa kulowetsa bendex).
Komanso, kusweka kwa pulagi ya bendix, yomwe imagwirizanitsa bendx ndi retractor relay, ingayambitse kuwonongeka. Ngati goli lithyoka, zida za freewheel sizigwira ntchito ndi flywheel.
M'kupita kwa nthawi, odzigudubuza amene ali kutsogolera kopanira angathenso fufutidwa. Amawoneka ang'ono kwambiri, koma ndikuthokoza kuti zida zimatha kuzungulira mbali imodzi yokha. Ngati zida zimazungulira momasuka mbali zonse, ndiye kuti izi zikuwonetsa ukwati kapena kuvala kwathunthu kwa odzigudubuza ndi kufooka kwa mbale zokakamiza.
Ndikoyenera kunena kuti choyambira ndi chipangizo chovuta kwambiri ndipo kusweka nthawi zambiri sikuchitika chifukwa cha bendix. Moyo woyambira ndi wocheperako kuposa wa injini, kotero posachedwa kapena mtsogolo uyenera kusinthidwa.
Kanema wa momwe bendix idabwezeretsedwera pokonza choyambira.
Tikutsegula...
