Mumotokari dzine manyorerwo ekufambisa, kutamiswa kwesimba kubva kune lever kuenda kune yekuchinja michina kunoitwa negear shift drive.Iyo shank inoita basa rakakosha mukushanda kwedhiraivha - verenga zvese nezve chikamu ichi, chinangwa chayo, mhando, dhizaini, pamwe nekusarudzwa kweshank nyowani uye kutsiva kwayo muchinyorwa.
Chii chinonzi gearbox shank
Iyo gearbox shank chinhu cheiyo gearbox shift drive ine manual control (mechanical gearboxes);Chikamu chinobatanidza zvakananga tsvimbo yekutyaira kune gear shift lever.
Iyo gearbox shank ine akati wandei mabasa:
- Kubatanidzwa kwedhiraivha tsvimbo uye kure kure giya shift mechanism;
- Kubhadhara kwelongitudinal uye transverse displacements yedhiraivha zvikamu mota ichifamba;
- Dhiraivha kugadzirisa.
Gearbox shanks anoshandiswa mugearshift madhiraivha akavakirwa pamatanda akaomarara, mune tambo madhiraivha, basa rechikamu ichi rinoitwa nezvimwe zvikamu (vashanduri).Shanks emhando dzakasiyana-siyana anogona kuwanikwa mumagiyashift madhiraivha emarori nemota, pamwe nematirakita nemimwe michina.Iyo shank, iri chikamu chegiya yekuchinja drive, inoita basa rakakosha mukutonga kwekutapurirana.Muchiitiko chekuputsika, chikamu ichi chinofanira kuchinjwa, uye nokuda kwechisarudzo chakarurama uye kubudirira kugadzirisa, unoda kuziva nezvemhando dziripo uye maitiro e shanks.
Mhando uye dhizaini yegiya bhokisi shanks
Iwo magiya bhokisi shanks anoshandiswa nhasi anogona kukamurwa kuita mhando zvichienderana nedhizaini uye nzira yekubatanidza neyegiya yekuchinja michina.
Nekugadzirwa, shanks ndeyemhando mbiri huru:
• Threaded tip;
• Tubular traction.
Iyo shank yerudzi rwekutanga ine dhizaini yakafanana neyekutungamirira matipi - iyi ipfupi tsvimbo yesimbi, kune rumwe rutivi iyo tambo inochekwa yekumisikidza mudhiraivha, uye kune rumwe rutivi kune hinge yekubatanidza. kune lever ye switching mechanism pane gearbox.
Iyo shank yerudzi rwechipiri isimbi tubular tsvimbo, iyo kune rumwe rutivi inogona kubatanidzwa kune iyo huru tsvimbo, uye kune rumwe rutivi ine hinge yekubatanidza neiyo switching mechanism pabhokisi regiya.Iyi shank inogona kubatanidzwa kune tsvimbo huru uchishandisa mabhuraketi kana simbi ine tambo yakasungwa.
Zvinoenderana neiyo nzira yekubatanidza neyegiya yekuchinja mashandiro, shanks ndeyemhando mbiri:
• Ne rubber-metal hinge (silent block);
• Nekubatana kwebhora.
Tubular gearbox shank ine bhora rakabatana uye bracket yejet thrust
Muchiitiko chekutanga, hinge ye-rubber-metal iri kumagumo e shank, uye kusungirirwa kune lever yemuchina wekushandura pabhokisi regiya rinoitwa uchishandisa bhoti.Muchiitiko chechipiri, bhora rekuchengetedza-isina bhora rinosungirirwa pane shank, pini iyo yakabatanidzwa kune lever yemuchina wekuchinja pane gearbox.Bhara majoini shanks anoshanda zvakanyanya, anotsiva zvirinani kusimuka uye kuchinjika kwenzvimbo dzekutyaira mota ichifamba (nekuda kwekusimuka kwegiya bhokisi, injini, cab, deformation yefuremu kana muviri, nezvimwewo) uye kurwisa vibrations.Shanks ane mabhururu akanyarara ari nyore uye akachipa, saka anoshandiswawo zvakanyanya.
Zvakare, gearbox shanks inogona kukamurwa kuita mapoka maviri zvichienderana nekuvapo kwekuwedzera kwekubatanidza:
• Pasina kuwedzera kubatanidzwa nezvikamu zvemotokari, aya mazano akaiswa tambo;
• Kubatanidza kune jet thrust (tsvimbo) ye gear shift drive.
Muchiitiko chekutanga, tsvimbo yekuita inobatanidzwa kune tsvimbo huru yemotokari.Muchiitiko chechipiri, bracket inopiwa pane shank, iyo iyo pini yejet thrust ball joint yakabatanidzwa.Mugumo wechipiri wetsvimbo yakabatana pivotally kune giya bhokisi dzimba kana (zvishoma kazhinji) kune yemotokari furemu.Kuvapo kwejet thrust kunodzivirira kungoerekana giya kushanduka apo mota ichifamba nekuda kwekutamiswa kwegiya bhokisi, cab, injini uye zvimwe zvikamu.
Gearshift drive ine shank muchimiro chetambo yakarukwa
Sezvatotaurwa, giya bhokisi shank rinotora nzvimbo yepakati pakati peiyo huru dhiraivha tsvimbo, iyo iyo giya lever mu cab yakabatana, uye yekuchinja masisitimu lever yakakwira yakananga pabhokisi regiya.Sezvo dhiraivha iri pasi pekuzunguzika uye mitoro yakakosha, tambo dzayo dzakabatanidzwa dzinopa dziviriro kubva kune inongoerekana yavhurika yenzungu.Iyo yakarukwa zano, sekutonga, ine locknut, uye kusungirirwa kwehinge nzungu padivi regiya bhokisi kunogona kuitiswa nepini yecotter (iyo inoshandiswa musimboti nut).Izvi zvinodzivirira kuwandisa backlash uye inovimbisa kushanda kwakavimbika kwekutyaira mumamiriro ese.
Nyaya dzekusarudza uye kutsiva gearbox shanks
Iyo gearbox shank chikamu chakavimbika uye chakasimba, asi mune dzimwe nguva kusashanda kunogona kuitika mairi.Dambudziko rinowanzoitika nderokupfeka kwehinges (bhora rekubatana kana chinyararire block), iyo inoratidzwa nekuwedzera kwekudzokera shure, kuwedzera kwesimba rekudengenyeka pane gear lever.Muchiitiko ichi, chikamu chinofanira kuchinjwa, sezvo kazhinji hinges haigoni kugadziriswa.Deformations uye kuputsika kweshank uye zvikamu zvavo zvega zvinogoneka - bhuraketi yejet thrust, clamp, nezvimwewo. Uye muzviitiko izvi, chikamu chinofanira kutsiviwa.
Paunosarudza shank itsva, zvakakosha kutungamirirwa nekabhuku yezvikamu zveimwe motokari, sezvo rudzi rwakasiyana rwe shank harugoni kushandiswa kakawanda.Kutsiviwa kwechikamu uye kugadziridzwa kweiyo gear shift drive kunofanirwa kuitwa zvinoenderana nekurudziro yekugadzirisa uye kugadzirisa kwemotokari.Kana basa rose rikaitwa nemazvo, iyo michina ichashanda yakavimbika, ichipa kudzora kwakavimbika kwekutapurirana uye mota yese.
