Dhizaini ye-multi-plate friction clutch uye yayo uye musimboti wekushanda

A multi-plate friction clutch imhando ye torque transmission mechanism iyo ine paki yekukwenya uye simbi discs. Iyo nguva inotapurirwa nekuda kweiyo friction force inoitika kana ma disc akamanikidzwa. Multi-plate clutches anoshandiswa zvakanyanya mumhando dzakasiyana dzekutakura mota. Funga nezvechigadzirwa, nheyo yekushanda, pamwe chete nezvakanaka uye zvisingabatsiri zvezvirongwa izvi.

Nheyo yekushanda kweclutch

Basa guru re-multi-plate clutch ndeyekunyatsobatanidza uye kubvisa iyo yekuisa (drive) uye inobuda (inotyairwa) shafts panguva yakakodzera nekuda kwesimba rekukwevera pakati pe disks. Muchiitiko ichi, torque inotamiswa kubva kune imwe shaft kuenda kune imwe. Madhisiki anodzvanywa nekumanikidzwa kwemvura.

Ndokumbira utarise kuti kukosha kweiyo torque yakapfuudzwa kwakakura, iyo yakasimba yekuonana kweiyo discs. Panguva yekushanda, clutch inogona kutsvedza, uye shaft inotyairwa inomhanyisa mushe pasina kuzununguka kana kuzununguka.

Mhedzisiro huru ye-multi-disk mechanism kubva kune vamwe ndeyokuti nekuwedzera kwenhamba ye disks, nhamba yezvikamu zvekubatana inowedzera, izvo zvinoita kuti zvikwanise kutumira torque yakawanda.

Nheyo yekushanda kwakajairika kweiyo friction clutch ndiko kuvapo kwegap rinogadziriswa pakati pemadhisiki. Iyi nhanho inofanirwa kuenderana nekukosha kwakatarwa nemugadziri. Kana mukaha pakati peclutch discs uri pasi pekukosha kwakatarwa, maclutches anogara ari mu "compressed" mamiriro uye anopera nekukurumidza zvinoenderana. Kana kureba kwakakura, kutsvedza kweclutch kunoonekwa panguva yekushanda. Uye munyaya iyi, kupfeka nokukurumidza hakugoni kudziviswa. Kunyatsogadziriswa kwezvipingamupinyi pakati pezvisungo pakugadzirisa kusungirirwa ndiyo kiyi yekushanda kwayo kwakarurama.

Kuvaka uye zvikamu zvikuru

Iyo yakawanda-ndiro friction clutch ndeye structural pasuru yesimbi uye alternating friction discs. Nhamba yavo yakananga zvinoenderana neiyo torque inofanira kufambiswa pakati pemashafts.

Saka, kune marudzi maviri ewasher mu clutch - simbi uye friction. Ndeupi musiyano uripo pakati pavo Chokwadi ndechekuti yechipiri mhando yepulley ine yakakosha yekupfeka inonzi "friction". Iyo yakagadzirwa nemhando yepamusoro yekukwesha zvinhu: ceramics, kabhoni kompositi, Kevlar shinda, nezvimwe.

Madhisiki anonyanyozivikanwa madhisiki esimbi ane friction layer. Nekudaro, hazvisi nguva dzose-zvakavakirwa simbi; dzimwe nguva izvi zvikamu zvekubatanidza zvinogadzirwa nepurasitiki yakasimba. Iwo madhisiki akabatanidzwa kune drive shaft hub.

Madhisiki esimbi asina frictionless akaiswa mudhiramu rakabatana neshaft inofambiswa.

Iyo clutch inewo piston uye chitubu chekudzoka. Pasi pechiito chekumanikidza kwemvura, piston inotsikirira pane disc pack, ichigadzira simba rekukwesha pakati pavo uye kuendesa torque. Mushure mekumanikidzwa kusunungurwa, chitubu chinodzorera piston uye clutch inosunungurwa.

Kune marudzi maviri e-multi-plate clutches: yakaoma uye yakanyorova. Rudzi rwechipiri rwemudziyo wakazadzwa nemafuta. Lubrication yakakosha kune:

• zvakanyanya kushanda kupisa kupisa;
• Lubrication yezvikamu zveclutch.

Wet multi-plate clutch ine imwe drawback - yakaderera coefficient of friction. Vagadziri vanotsiva kukanganisa uku nekuwedzera kudzvanywa kwedhisiki uye kushandisa yazvino friction zvinhu.

Kubatsira uye kuipa

Zvakanakira zvemulti-plate friction clutch:

• compactness;
• Paunenge uchishandisa multi-plate clutch, zviyero zveyuniti zvakaderedzwa zvakanyanya;
• kutapurirana kwe torque yakakosha ine zvidiki zvidiki zvemashini (nekuda kwekuwedzera kwenhamba ye disks);
• kupfava kwebasa;
• mukana wekubatanidza dhiraivha shaft uye inofambiswa shaft coaxially.

Zvisinei, iyi michina haina zvipingamupinyi. Semuenzaniso, simbi uye friction discs zvinogona kupisa panguva yekushanda. Mumvura yakawanda-plate clutches, coefficient of friction inoshandukawo sezvo viscosity ye lubricant inoshanduka.

Kubatanidza kunyorera

Multi-plate clutches anoshandiswa zvakanyanya mumotokari. Ichi chishandiso chinoshandiswa mune zvinotevera masisitimu:

• clutch (muCVTs pasina torque converter);
• Otomatiki kutapurirana (otomatiki kutapurirana): Iyo otomatiki transmission clutch inoshandiswa kufambisa torque kune yepuraneti giya seti.
• Robhoti giya bhokisi: Iyo mbiri mbiri clutch disc pack murobhoti giya bhokisi inoshandiswa kuchinjika nekumhanya kwakanyanya.
• Ese-vhiri dhiraivha masisitimu: iyo friction mudziyo inovakwa mune yekutamisa kesi (clutch inodiwa pano kuti ivhare otomatiki musiyano wepakati);
• Kusiyanisa: mechanical device inoita basa rekuvharira kuzere kana kusara.
