A viscous coupling, kana viscous coupling, imwe yemotokari yekufambisa zvikamu zvinoshandiswa kufambisa uye kuenzana torque. A viscous coupling inoshandiswawo kuendesa kutenderera kune radiator inotonhorera fan. Havasi vese varidzi vemotokari vanonyatsoziva mudziyo uye musimboti wekushanda kweiyo viscous coupling, saka takasarudza kupa chimwe chezvinyorwa pane yedu vodi.su portal kune iyi nyaya.

Chokutanga pane zvose, munhu haafaniri kuvhiringidza musimboti wekushanda kwekubatanidza viscous ne hydraulic coupling kana torque converter, umo kuendesa torque kunoitika nekuda kwemasimba emafuta. Panyaya yekubatanidza viscous, nheyo yakasiyana zvachose inoshandiswa - viscosity. Chinhu chacho ndechekuti dilatant fluid yakavakirwa pasilicon oxide, kureva, silicone, inodururwa mugomba rekubatanidza.

Chii chinonzi dilatant fluid? Iyo isiri-Newtonian fluid iyo viscosity inoenderana nevelocity gradient uye inowedzera nekuwedzera kweshear strain rate.. Iyi ndiyo nzira iyo maitiro makuru emvura inoyerera inotsanangurwa mune encyclopedias uye zvinyorwa zvehunyanzvi.

Kana tikaturikira magadzirirwo ese aya mumutauro unonzwisisika kune ruzhinji rwevanhu, tichaona kuti dilatent risiri reNewtonian fluid rinoita kuoma (kuwedzera viscosity) nekukurumidza kusanganiswa. Mvura iyi inoomesa nekumhanya uko crankshaft yemotokari inotenderera, kureva kuti, inenge 1500 rpm uye pamusoro.

Wakakwanisa sei kushandisa chivakwa ichi muindasitiri yemotokari? Izvo zvinofanirwa kutaurwa kuti iyo viscous coupling yakagadzirwa kumashure muna 1917 neAmerican injiniya Melvin Severn. Mumakore iwayo ari kure, pakanga pasina chikumbiro chekubatanidza viscous, saka kugadzirwa kwakaenda kusherufu. Kekutanga, yaifungidzirwa kuishandisa senzira yekuzvivharira otomatiki musiyano wepakati mumakore makumi matanhatu ezana ramakore rapfuura. Uye vakatanga kuiisa pa-all-wheel drive SUVs.

Device

Chigadzirwa chacho chiri nyore:

  • iyo clutch iri muchimiro chehumburumbira;
  • mukati mune mashafu maviri asingadyidzani pamwe chete mune yakajairika mamiriro - kutyaira uye inotyairwa;
  • akakosha anotungamira uye anotyairwa simbi dhisiki akasungirirwa kwavari - kune akawanda kwazvo, iwo anowanikwa coaxially uye ari padiki chinhambwe kubva kune mumwe.

Izvo zvakakosha kuti ticherechedze kuti isu takatsanangura chizvarwa chitsva viscous coupling. Imwe vhezheni yekare yaive silinda diki yehermetic ine mashaft maviri, paiiswa ma impeller maviri. Mashaft haana kusangana.

Kuziva mudziyo, unogona kufungidzira zviri nyore musimboti wekushanda. Semuenzaniso, kana mota ine plug-in all-wheel drive iri kutyaira mumugwagwa mukuru, kutenderera kubva painjini kunofambiswa chete kune ekisero yekumberi. Iyo shafts uye madhisiki eiyo viscous coupling inotenderera nekumhanya kwakafanana, saka hapana kusanganiswa kwemafuta mudzimba.

Mota painotyaira mumugwagwa une tsvina kana kuti une sinou uye mavhiri ari pane imwe ekisero otanga kutsvedza, mashaft ari mukubatana kwe viscous anotanga kutenderera nekumhanya kwakasiyana. Izvo zviri pasi pemamiriro ezvinhu akadaro izvo zvimiro zve delatant zvinwiwa zvinozviratidza - ivo vanokurumidza kusimba. Saizvozvo, simba rekukwevera kubva muinjini rinotanga kugoverwa zvakaenzana kune ese ari maviri. All-wheel drive inobatika.

Sezvineiwo, viscosity yemvura inoyerera inoenderana nekumhanya kwekutenderera. Iyo inokurumidza imwe yeaxes inotenderera, iyo inowedzera viscous iyo mvura inova, ichiwana zvimiro zveakasimba. Uye zvakare, azvino maviscous couplings akagadzirwa nenzira yekuti nekuda kwekumanikidzwa kwemafuta, madhisiki uye shafts zvakanamirwa pamwe chete, kuve nechokwadi chekufambisa kwakavimbika kweiyo torque yakakura kune ese mavhiri axles.

Iyo viscous coupling yeinotonhora sisitimu inoshanda pamusimboti mumwechete, ichinyatso kudzora kumhanya kwe fan. Kana injini iri kumhanya yakaderera pasina kupisa, ipapo viscosity yemvura haina kuwedzera zvakanyanya. Saizvozvo, iyo fan haina kumhanya zvakanyanya. Kana kukurumidza kunowedzera, kusanganiswa uye kusimba kwemafuta mu clutch kunoitika. Iyo fan inotanga kutenderera kunyange nekukurumidza, ichitungamira mhepo inoyerera kumaseru eradiator.

Pros uye Cons 

Sezvauri kuona kubva pane iri pamusoro ruzivo, iyo viscous coupling ndeye yakanakisa kugadzirwa. Asi mumakore achangopfuura, vagadziri vemotokari vakaramba zvakanyanya kuimisa, vachisarudza kumanikidzwa kudzorwa Haldex clutches. Izvi zvinokonzerwa nekuti kushandisa viscous couplings pane ese-mavhiri dhiraivha mota neABS kune dambudziko.

Uye zvakare, kunyangwe iri nyore dhizaini, iyo viscous coupling ihuru yekutapurirana unit. Huremu hwemotokari hunowedzera, kubvisirwa pasi kunoderera. Zvakanaka, sekuratidzira kunoratidza, kuzvidzora-kuzvivharira zvakasiyana neine viscous clutch hazvishande zvakanyanya.

Pros:

  • simple design;
  • inogona kugadziriswa pachayo (fan clutch);
  • hermetic kesi;
  • hupenyu hwakareba hwebasa.

Pane imwe nguva, ma-viscous couplings akaiswa pamotokari dzese-vhiri dzeanenge ese anozivikanwa makambani emotokari: Volvo, Toyota, Land Rover, Subaru, Vauxhall / Opel, Jeep Grand Cherokee, etc. Nhasi, masisitimu emagetsi ane kuvharika kwekumanikidza ari preferred. Zvakanaka, mujini yekutonhodza system, ma-viscous couplings achiri kuiswa pamhando dzakawanda dzemotokari: VAG, Opel, Ford, AvtoVAZ, KamAZ, MAZ, Cummins, YaMZ, ZMZ injini.

Iyo viscous coupling inoshanda sei
