The gearbox vavu thupi DL501 0B5 ndi oyenera Audi A4 A5 mbali galimoto

1. Makokedwe ogwiritsira ntchito Makokedwe ogwiritsira ntchito ndiye gawo lofunikira kwambiri pakusankha chipangizo chamagetsi cha valavu, ndipo torque yotulutsa chipangizo chamagetsi iyenera kukhala 1.2 ~ 1.5 nthawi yanthawi yayitali yogwiritsira ntchito valavu.

2. Pali zida ziwiri zazikulu za injini zogwiritsira ntchito chipangizo chamagetsi cha valavu yothamangitsira: imodzi ndiyo kutulutsa torque molunjika popanda gitala; Chinanso ndikukhazikitsa thrust disc, ndipo torque yotulutsa imasinthidwa kukhala kutulutsa kotulutsa kudzera mu nati ya valve mu thrust disc.

3. Chiwerengero cha kutembenuka kwa shaft yotulutsa Chiwerengero cha kutembenuka kwa shaft yotulutsa ya chipangizo chamagetsi cha valavu chikugwirizana ndi m'mimba mwake mwadzina la valavu, ulusi wa tsinde la valve ndi chiwerengero cha mitu ya ulusi, ndipo ziyenera kuwerengedwa. malinga ndi m = h/zs (m ndi chiwerengero chonse cha matembenuzidwe omwe chipangizo chamagetsi chiyenera kukumana nacho, h ndi kutalika kwa valavu, s ndi ulusi wa kufalikira kwa tsinde la valve, ndipo z ndi chiwerengero cha mitu ya ulusi wa tsinde la valve).

4, tsinde la tsinde Kwa ma valve otseguka-otseguka, ngati kutalika kwa tsinde komwe kumaloledwa ndi chipangizo chamagetsi sikungadutse pa tsinde la valve, sikungasonkhanitsidwe mu valve yamagetsi. Choncho, m'mimba mwake mkati mwa dzenje lotulutsa shaft ya chipangizo chamagetsi chiyenera kukhala chokulirapo kusiyana ndi kunja kwa tsinde la valve yowonekera. Kwa ma valve ena ozungulira ndi ma valve obisika a tsinde mu ma valve ambiri ozungulira, kupitirira kwa tsinde sikofunikira, koma tsinde la tsinde ndi kukula kwa keyway ziyenera kuganiziridwa bwino pakusankhidwa, kuti athe kugwira ntchito mwachizolowezi pambuyo pa msonkhano.

5, ngati kutsegula ndi kutseka liwiro la valavu yotuluka mofulumira kwambiri, n'zosavuta kupanga chodabwitsa cha nyundo yamadzi. Choncho, liwiro loyenera lotsegula ndi kutseka liyenera kusankhidwa malinga ndi zochitika zosiyanasiyana za utumiki.

6, valavu yamagetsi yamagetsi ili ndi zofunikira zake zapadera, zomwe ziyenera kuchepetsa mphamvu ya torque kapena axial. Nthawi zambiri, chipangizo chamagetsi cha valve chimatenga cholumikizira chomwe chimachepetsa torque. Pamene zofunikira za chipangizo chamagetsi zimatsimikiziridwa, torque yake yolamulira imatsimikiziridwanso. Nthawi zambiri, imayenda mkati mwa nthawi yoikidwiratu, ndipo mota siyidzadzaza. Komabe, ngati zotsatirazi zikuchitika, zingayambitse kuchulukirachulukira: choyamba, mphamvu yamagetsi imakhala yochepa, ndipo torque yofunikira siyingapezeke, kotero kuti galimotoyo imasiya kuzungulira; Chachiwiri, njira yochepetsera ma torque imayikidwa molakwika kuti ikhale yayikulu kuposa torque yoyimitsa, zomwe zimapangitsa kuti pakhale torque yambiri ndikuyimitsa mota; Chachitatu, kugwiritsa ntchito pakanthawi kochepa, zomwe zimapangitsa kuti pakhale kutentha, kupitilira kutentha kovomerezeka kwagalimoto; Chachinayi, kuzungulira kwa makina oletsa ma torque kumalephera pazifukwa zina, zomwe zimapangitsa kuti torque ikhale yayikulu kwambiri; Chachisanu, kutentha kwa malo ogwirira ntchito ndikokwera kwambiri, zomwe zimapangitsa kutentha kwa injini kucheperachepera.

7. Chipangizo chamagetsi cha valve ndi chida chofunikira kwambiri kuti muzindikire kuwongolera pulogalamu, kuwongolera zokha komanso kuwongolera kutali kwa valavu, ndipo kayendetsedwe kake kakhoza kuyendetsedwa ndi kukwapula, torque kapena axial thrust. Chifukwa mawonekedwe ogwirira ntchito ndi kuchuluka kwa magwiritsidwe a chipangizo chamagetsi cha valavu zimadalira mtundu wa valavu, momwe chipangizocho chimagwirira ntchito komanso malo a valavu papaipi kapena zida, ndikofunikira kusankha chida chamagetsi cha valve molondola kuti mupewe kuchulukirachulukira. (makokedwe ogwira ntchito ndi apamwamba kuposa torque yowongolera).
