M'magalimoto okhala ndi ma transmissions amanja, kusamutsa mphamvu kuchokera ku lever kupita kumakina osinthira kumayendetsedwa ndi ma gear shift drive.Shank imakhala ndi gawo lofunikira pakuyendetsa galimoto - werengani zonse za gawoli, cholinga chake, mitundu, mapangidwe, komanso kusankha shank yatsopano ndikusintha m'nkhaniyi.
Kodi shank ya gearbox ndi chiyani
The gearbox shank ndi gawo la gearbox shift drive yokhala ndi zowongolera pamanja (ma giya magiya);Gawo lomwe limagwirizanitsa mwachindunji ndodo yoyendetsa galimoto ku gear shift lever.
The gearbox shank ili ndi ntchito zingapo:
- Kulumikizana kwa ndodo yoyendetsa ndi njira yosinthira zida zakutali;
- Kulipiridwa kwa kusuntha kwakutali ndi kodutsa kwa magawo agalimoto pomwe galimoto ikuyenda;
- Kusintha kwagalimoto.
Zingwe za Gearbox zimagwiritsidwa ntchito pamayendedwe a gearshift potengera ndodo zolimba, pamagalimoto a chingwe, gawo ili limaseweredwa ndi zigawo zina (omasulira).Ma shank amitundu yosiyanasiyana amapezeka pamagalimoto oyendetsa magalimoto ndi magalimoto, komanso mathirakitala ndi zida zina.Shank, pokhala gawo la gear shift drive, imagwira ntchito yofunikira pakuwongolera kufalitsa.Pakawonongeka, gawoli liyenera kusinthidwa, ndipo kuti musankhe bwino ndikukonza bwino, muyenera kudziwa za mitundu yomwe ilipo komanso mawonekedwe a shank.
Mitundu ndi kapangidwe ka ma shank a gearbox
Ma shank a gearbox omwe amagwiritsidwa ntchito masiku ano amatha kugawidwa m'mitundu malinga ndi kapangidwe kake ndi njira yolumikizirana ndi makina osinthira zida.
Mwa mapangidwe, zibowo zili zamitundu iwiri ikuluikulu:
• Nsonga ya ulusi;
• Kuthamanga kwa tubular.
Shank yamtundu woyamba imakhala ndi mapangidwe ofanana ndi nsonga zowongolera - iyi ndi ndodo yaifupi yachitsulo, yomwe mbali imodzi yomwe ulusi umadulidwa kuti ukhazikike mu ndodo yoyendetsa, ndipo kumbali ina pali hinge yolumikizira. ku lever ya makina osinthira pa gearbox.
Shank yamtundu wachiwiri ndi ndodo yachitsulo, yomwe mbali imodzi imatha kulumikizidwa ndi ndodo yayikulu, ndipo mbali inayo imakhala ndi hinge yolumikizira makina osinthira pabokosi la gear.Shank iyi imatha kulumikizidwa ku ndodo yayikulu pogwiritsa ntchito mabatani kapena chomangira chokhala ndi ulusi wowongolera.
Malinga ndi njira yolumikizirana ndi makina osinthira zida, zibowo zili zamitundu iwiri:
• Ndi hinge ya rabara-zitsulo (chidacho chete);
• Polumikizana ndi mpira.
Tubular gearbox shank yokhala ndi cholumikizira mpira ndi bulaketi ya jet thrust
Pachiyambi choyamba, mphira yachitsulo-rabara ili kumapeto kwa shank, ndipo kugwirizanitsa ndi lever ya makina osinthira pa gearbox kumachitika pogwiritsa ntchito bolt.Pachitsanzo chachiwiri, cholumikizira champira chopanda kukonza chimayikidwa pa shank, pini yomwe imalumikizidwa ndi lever ya makina osinthira pa gearbox.Mpira olowa zingwe ndi kothandiza kwambiri, iwo bwino kubweza kwa nthawi yaitali ndi yopingasa kusamuka kwa mbali galimoto pamene galimoto ikuyenda (chifukwa kusamutsidwa kwa gearbox, injini, kabati, mapindikidwe chimango kapena thupi, etc.) ndi kugunda kugwedezeka.Ma shanks okhala ndi midadada opanda phokoso ndi osavuta komanso otsika mtengo, choncho amagwiritsidwanso ntchito kwambiri.
Komanso, zibowo za gearbox zitha kugawidwa m'magulu awiri malinga ndi kupezeka kwa maulumikizidwe owonjezera:
• Popanda maulumikizidwe owonjezera ndi magawo oyendetsa, awa ndi malangizo opangidwa ndi ulusi;
• Kulumikizana ndi jet thrust (ndodo) ya gear shift drive.
Munthawi yoyamba, ndodo yamachitidwe imalumikizidwa ndi ndodo yayikulu yagalimoto.Chachiwiri, bulaketi imaperekedwa pa shank, yomwe pini ya jet thrust mpira imalumikizidwa.Mapeto achiwiri a ndodo amalumikizidwa kwambiri ndi nyumba ya gearbox kapena (kawirikawiri) ku chimango chagalimoto.Kukhalapo kwa jet thrust kumalepheretsa kusuntha modzidzimutsa pamene galimoto ikuyenda chifukwa cha kusuntha kwa gearbox, cab, injini ndi mbali zina.
Gearshift drive yokhala ndi shank ngati nsonga ya ulusi
Monga tanenera kale, shank ya gearbox imakhala ndi malo apakati pakati pa ndodo yaikulu yoyendetsa galimoto, yomwe imagwirizanitsa ndi lever mu kabati, ndipo makina osinthika amayikidwa mwachindunji pa gearbox.Popeza galimotoyo imakhala ndi kugwedezeka komanso kunyamula katundu wambiri, maulalo ake a ulusi amateteza kuti mtedza usatuluke.Nsonga yokhotakhota, monga lamulo, imakhala ndi locknut, ndipo kugwedeza kwa mtedza wa hinge kumbali ya gearbox kungathe kuchitidwa ndi pini ya cotter (yomwe imagwiritsidwa ntchito ndi mtedza wapakati).Izi zimalepheretsa kubwereranso kochulukirapo ndikuwonetsetsa kuyendetsa kodalirika kwagalimoto muzochitika zonse.
Nkhani zakusankha ndikusintha ma shank a gearbox
Gearbox shank ndi gawo lodalirika komanso lolimba, koma nthawi zina zosokoneza zimatha kuchitika.Vuto lofala kwambiri ndi kuvala kwa ma hinges (kulumikizana kwa mpira kapena chipika chopanda phokoso), chomwe chimawonetsedwa ndi kuwonjezereka kwa mmbuyo, kuwonjezeka kwamphamvu kwa kugwedezeka kwa lever ya gear.Pankhaniyi, gawolo liyenera kusinthidwa, chifukwa nthawi zambiri mahinji sangathe kukonzedwa.Ma deformations ndi kuwonongeka kwa ziboda ndi ziwalo zawo payekha ndi zotheka - bulaketi kwa jet thrust, achepetsa, etc. Ndipo muzochitika izi, gawolo liyenera kusinthidwa.
Posankha shank yatsopano, m'pofunika kutsogoleredwa ndi kabukhu la magawo a galimoto inayake, popeza mtundu wina wa shank sungagwiritsidwe ntchito nthawi zambiri.Kusintha kwa gawo ndi kusintha kwa galimoto yoyendetsa galimoto kuyenera kuchitidwa motsatira ndondomeko yokonza ndi kukonza galimotoyo.Ngati ntchito zonse zachitika molondola, limagwirira ntchito modalirika, kupereka ulamuliro molimba mtima kufala ndi galimoto lonse.
