Cardan-gred prečka, kako narediti zamenjavo križev kardanske gredi

Če pri premikanju vozila, karakteristična točenje prihaja iz njega, in čudna vibracija se čuti v kabini, potem pa je najverjetneje čas, da zamenjate prečkate kardanske gredi. Seveda lahko ti simptomi kažejo, da ne samo neuspeh Kandannaya križi, in druge napake, zato je najprej izvedena diagnostika. O tem v članku.

Kardanska gred je element prenosov vseh vozil pogona na vsa kolesa in voznika zadnje kolo. To je gred, ki prenaša navor iz škatle za prenos ali menjalnik na zadnji ali sprednji redukcijski reduktor. Treba je omeniti, da je kardanska gred tako edinstvena in preprosta, da se v mnogih desetletjih njegova zasnova dejansko ne spremeni.

Pogonska gred je lahko en sam del, dvodelna in tristranska. Sestavljeni so iz več komponent - dva prečkanja, gredi, tesnila, drsnih vilic, pritrdilnih delov in številnih drugih elementov, ki so praviloma odvisne od zasnove. Teža, debelina in dolžina gredi je posledica dimenzij vozila. Treba je omeniti, da so športni avtomobili zaključeni z enim odsekom gredi. Na primer, en genering Cardan se uporablja v zasnovi Nissan GT-R.

Kardanska gred je eden najbolj vzdržljivih avtomobilskih elementov. To je enostavno, da razstavi, in popravilo temelji na zamenjavi vzmetenja ležaja in križem.

Znaki okvare prečkanja kardanske gredi se lahko pripišejo:

  1. Občutek pretepanja in potrkanja v šasijo.
  2. Ko se dotaknete s prizora, se iz ohišja sliši čisto kovinsko zvonjenje.
  3. Prisotnost vibracij v avtu.

Diagnostični zlom, kako narediti diagnostiko z lastnimi rokami

Za samo-diagnostiko je treba iti na vozilo. Z eno roko pritrdite gred in druga je prirobnica vodilnega gonila. Nato jih obrnite drug proti drugemu. Prisotnost tudi najmanjša zanka kaže, da je primer res na križu. Čeprav, če je bil noben ležaj, ne sme biti. V tem primeru preverite stanje lahko vizualno, za kar morate odklopiti pogonsko gred iz prirobnice s tipko na "13" in ocenite stanje. Pred razstavljanjem uporabite nalepke, da bi se izognili nepravilni montaži.

Orodja in napeljave za popravilo

  1. Iz kovine (bakra ali aluminija).
  2. Crosshead izvijač.
  3. Passatia.
  4. Ključi za obraza in rog, katerih dimenzije "27", "13", "12".
  5. Kladivo.

Rezervni deli, kateri deli so potrebni pri zamenjavi križev kardanske gredi

  1. Zadrževalni obročki.
  2. Suspendiran ležaj.
  3. Križ kardanske gredi.
  4. Poleg tega se lahko zahtevajo nove matice in vijake, saj se lahko zatekajo, kar povzroči, da se pogosto poškodujejo, ko so odvijete.

Nov križ, zakaj bi imel enako številko oznake kot prejšnji križ

Ne pozabite, da mora biti nova prečkana enaka oznake z odstranljivim analogom, sicer pa bo problem rešil z razgradnjo.

Prva stvar, ki jo je treba storiti, je, da označite, kako so vilice uredili prehod, saj so pri proizvajalcu nujno uravnoteženje in ko ponovno nameščajo kardan, povzroči vibracije. Prvič, odstranite zaustavitvene obroče. Najbolje je to s pomočjo posebnega ostrega prehoda. Na specializiranih delavnicah se ležaji stisnejo s hidravličnim ali ročnim tiskanjem, med neodvisnimi popravili pa je to težavo mogoče rešiti s pomočjo barve z mehkim materialom in kladivom. Nato vzemite par ležajev iz čepa. Z drugim paromčnim ležajem izvedemo podobno operacijo. Prav tako morate očistiti sedežne luknje in utore za zaklepanje obročev. Kožo lahko uporabite (plitvo ali srednje žito). Poleg tega je možno odstraniti majhne burtr z datoteko z datoteko, ki se včasih pojavi, ko iztrebljanje ležajev.

Druga faza je namestitev novih križev. Z obeh strani je potrebno odstraniti skodelice in napolnite oko prečke, nato pa lepo oblečete eno od skodelic, da ne raztresite igle v njem. Nato uporabite barvo, da poravnate skodelico, dokler se ne prikaže odstranitev za blokirni obroč. Nato ga nameravam, nato pa Cardan.

Nato se prav tako nežno premakne s križem v smeri skodelice in jo nosite podobno kot na prejšnjo situacijo, to je, dokler se ne prikaže utor zaklepanja. Namestite zadrževalni obroč. Na tej stopnji bodite še posebej previdni, ker je namestitev druge skodelice bolj zapletena dela kot vgradnja prvega, še posebej, če tega niste naredili prej. Kljub zapletenosti pa je še vedno izvedljivo. Glavna stvar je biti potrpežljiva in to počasi.

Zdaj pojdite na viseči ležaj. Ko je prečkana odstranjena, vstavite rezalni konec kardana v prirobnico stare sklopke. Uporaba ključa do "27", odvijemo matico, ki je pritrjena na sprednjo gred switard tečaja.

Pri namestitvi ne pozabite nanesite mazivo (večina proizvajalcev je opremljena z dodatnimi ležaji za mazivo). Ni nujno, da sami mazajo konic, saj je mogoče videti zračno blazino, ki je sposobna močno ovirati želeno natančno pozicioniranje elementov. Pred samim namestitvijo odstranite zaščitno manšeto iz ene konice, saj lahko ustvari oviro za vgradnjo križev vtič.

Strogo upoštevajte tehnologijo montaža kardanskega tečaja. Posebno pozornost je treba nameniti izjemu destilacije, saj bo opravljeno delo zaman in bo moralo ponovno razstaviti križ. Najboljša možnost za stiskanje bo posebna podpredsednica. Pri nanašanje, plošče in kladivo so čim bolj previdni, saj obstaja nevarnost poškodovanja križa.
