Kunyangwe chinhu chakadaro chisingaoneki sevhiri rinotakura zvinonyanya kutarisisa maitiro uye mabatiro emota. Mota dzeNissan Qashqai dzinoshandisa maangular contact bearings, ayo, muchokwadi, akabatana neiyo hub mechanism. Zvinokosha kuziva kuti kusvika 2007 iyi unit muQashqai yakanga yaparara, kureva kuti, kutakura kunogona kutsiviwa zvakasiyana kubva kune hub.

General information

Iyo hubhu yakagadzirirwa kugadzirisa vhiri remotokari pane axis yekutenderera (trunnion) kana axle danda. Ichi chinhu chakanamirwa kune chidhiraivho knuckle, iyo yakabatana kune yakamiswa strut. Iyo furemu, zvakare, inosungirirwa kumuviri wemotokari.

Iyo hubhu inopa kwete chete kuiswa kwemavhiri, asiwo kutenderera kwavo. Kuburikidza naro, torque kubva ku crankshaft inoendeswa kune vhiri. Kana mavhiri ari kutyaira, saka ichi chinhu chekufambisa kwemotokari.

Kutakura kwevhiri kunobatanidza vhiri kuhubhu kana chidhiraivho. Mukuwedzera, inoita mabasa anotevera:

• inoderedza kukwesha masimba kana uchitumira torque;
• inogovera radial uye axial mitoro inobva pavhiri kusvika kune axle uye kumiswa kwemotokari (uye zvinopesana);
• inoburitsa axle shaft ye drive axle.

Mumotokari dzeNissan Qashqai, avhareji yekubereka hupenyu inosiyana kubva pamakumi matanhatu kusvika zana ezviuru zvemakiromita.

Kutyaira mota ine vhiri rakashata kune njodzi. Mumamiriro ezvinhu akadaro, njodzi yekurasikirwa nekutonga uye kubata kwemotokari panzira inowedzera.

Node malfunction zviratidzo

Icho chokwadi chekuti muridzi wemotokari achakurumidza kutsiva vhiri rinotakura neNissan Qashqai inogona kuratidzwa nezviratidzo senge:

• ruzha rwakadzikama pakumhanya kwe40-80 km / h kubva parutivi rwekusashanda;
• kudengenyeka kwevhiri, throttle uye muviri pasina zvikonzero chinangwa;
• mapundu anoshamisa mukumiswa;
• kusiya motokari kudivi paunenge uchityaira (inenge yakangofanana nekurongeka kusina kunaka kwevhiri);
• kurira, "gurgling", mamwe manzwi ekunze kubva kudivi rakashata.

Chiratidzo chakanyanya kukosha uye chakajairika chinoratidza kutadza kubereka ndeye monotonous rolling ruzha runowedzera nekukurumidza. Vamwe varidzi vemotokari vanoienzanisa nokutinhira kwejini yejeti.

Diagnostics

Iwe unogona kuona kubva kune rumwe rutivi ruzha rusingafadzi runonzwika panguva yekufamba kwemotokari, nguva nenguva shanduko mukumhanya, kutendeuka uye braking. Varidzi veNissan Qashqai vane ruzivo vanoti iwe unogona kuona iro rakakanganisika kana uchikona. Zvinotendwa kuti kana uchitendeukira kune "dambudziko" nzira, iyo buzzing inowanzova yakanyarara kana kunyangarika.

Kuti uongorore hukuru uye chimiro chedambudziko nemaoko, unogona kuita zvinotevera:

•  isa motokari panzvimbo yakati sandara;
• maoko anotenderedza vhiri kumusoro kumusoro.

Kupfekwa kwemavhiri kunoonekwa uye ruzha rusinganzwisisike rwekugaya runenge ruchiratidzira kupera kwemavhiri.

Iwe unogona zvakare kuwana mamwe echokwadi node state ruzivo seizvi:

•  jack inoiswa kubva parutivi rwemota iri kuongororwa, mota inosimudzwa;
•  tenderera vhiri, uchipa iyo yakanyanya kumhanyisa.

Kana, panguva yekutenderera, creak kana mamwe manzwi ekunze anonzwika kubva parutivi rwevhiri, izvi zvinoratidza kusashanda kana kupera kwekutakura.

Mota dzemberi dzinotyaira mavhiri dzinogona kutariswa pane inosimudza. Kuti uite izvi, simudza mota, tanga injini, vhura giya uye mhanyisa mavhiri kusvika 3500-4000 rpm. Mushure mekudzima injini, kurira kusinganzwisisike, creaking kana creaking inonzwika kubva kudivi rakashata. Zvakare, kuvepo kwedambudziko kunozoratidzwa neinocherekedza backlash painopeperetsa uye kutenderera vhiri.

Kutsiva Zvikamu

Kana iyi musangano wepasi pengoro ikatadza, zvikamu zvechokwadi zveNissan zvinokurudzirwa. Neimwe nzira, zvigadzirwa kubva kumhando dzeJapan Justdrive uye YNXauto, iyo yeGerman Optimal kana yeSweden SKF inogona zvakare kuve yakakodzera. Hubs SKF VKBA 6996, GH 32960 inofarirwa nevaridzi veNissan Qashqai.

3.  gadzirisa brake disc ne screwdriver;
4. sunungura hub nut;
5. sunungura chidhiraivho chepfundo;
6. sunungura iyo CV yakabatana nati uye uibvise kubva kuhubhu;
7.  sunungura pini yebhora, bvisa gumbo rekutungamirira;
8.  bvisa nzvimbo yekare;
9. shandisa chibhakera chako kusimbisa mabhaudhi ehubhu.
