Chigadzirwa uye musimboti wekushanda kweEGUR Servotronic

Servotronic electro-hydraulic simba mudhiraivho chinhu chemutyairi wemotokari icho chinogadzira simba rekuwedzera kana mutyairi achichinjisa chidhiraivho. Muchokwadi, iyo magetsi emagetsi emagetsi (EGUR) isimba remagetsi rinotungamira. Iyo electrohydraulic booster ine dhizaini yakavandudzwa, pamwe nehurefu hwenyaradzo kana uchityaira chero kumhanya. Funga musimboti kushanda, chikuru zvinoriumba, uyewo zvakanakira ichi gozvo chinhu.

Nheyo yekushanda kweEGUR Servotronic

Nheyo yekushanda kwemagetsi emagetsi emagetsi yakafanana neiya emagetsi emagetsi. Musiyano mukuru ndewekuti pombi yemagetsi inofambiswa neinjini yemagetsi, kwete injini yemoto yemukati.

Kana mota ichifamba yakananga kumberi (mudhiraivhi hautendeuki), ipapo mvura irimo muchirongwa inongotenderera ichibva papombi inofambisa simba kuenda kudziva uye zvinopesana. Kana mutyairi atenderedza vhiri, kutenderera kwemvura inoshanda kunomira. Zvichienderana nekwaitenderera kutenderera kwechairi vhiri, inozadza imwe mhango yesirinda yemagetsi. Liquid kubva pakatarisana mhango inopinda mutangi. Mushure meizvozvo, inoyerera inoshanda inotanga kudzvanya padhiraivho nerubatsiro rwepiston, ipapo simba rinotamisirwa kumatanda ekutenderera, uye mavhiri anotendeuka.

Hydraulic simba mudhiraivho rinoshanda zvakanyanya pazasi kumhanya (kukona munzvimbo dzakamanikana, kupaka). Panguva ino, mota yemagetsi inotenderera nekukurumidza, uye pombi yekufambisa simba inoshanda zvakanyanya. Panyaya iyi, mutyairi haadi kushandisa simba chairo pakutenderedza chidhiraivho. Iyo yakakwirira kumhanya kwemota, mota inononoka kumhanya.

Mudziyo uye zvikamu zvikuru

EGUR Servotronic ine zvinhu zvitatu zvakakosha: yemagetsi control system, yepombi unit uye hydraulic control unit.

Iyo yekupomba unit ye ​​electro-hydraulic booster ine dura remvura inoshanda, pombi ye hydraulic uye mota yemagetsi yacho. Elektroniki control unit (ECU) inoiswa pachinhu ichi. Ziva kuti pombi yemagetsi iri yemhando mbiri: giya uye vane. Rudzi rwekutanga rwepombi runosiyaniswa nekureruka uye kuvimbika.

Iyo hydraulic control unit inosanganisira silinda yemagetsi ine pisitoni uye torsion bar (torsion rod) ine sleeve yekuparadzira uye spool. Ichi chikamu chakabatanidzwa nemagiya ekufambisa. Iyo hydraulic unit inyanzvi yekugadzirisa.

Servotronic zvemagetsi kudzora system:

• Inzwa yekuisa - yekumhanyisa sensor, yekutyaira torque sensor. Kana mota yakashongedzerwa neESP, iyo yekumonera sensor inoshandiswa. Iyo sisitimu zvakare inoongorora iyo injini yekumhanyisa data.
• Zvemagetsi zvekutonga unit. Iyo ECU inogadzirisa masaini kubva kuma sensors, uye mushure mekuiongorora, inotumira rairo kuchishandiso.
• Executive mudziyo. Zvichienderana nerudzi rwe electro-hydraulic gudzazwi, iyo actuator inogona kunge iri pombi yemagetsi mota kana vharuvhu yemagetsi mu hydraulic system. Kana mota yemagetsi yaiswa, mashandiro eamudziri anoenderana nesimba remota. Kana solenoid vharafu yaiswa, ipapo mashandiro ehurongwa anoenderana nesaizi yenzvimbo inoyerera.

Misiyano kubva kune mamwe marudzi emagetsi

Sezvambotaurwa kare, kusiyana neyakajairwa simba kudhiraivhu, EGUR Servotronic inosanganisira yemagetsi mota iyo inotyaira pombi (kana imwe actuator - solenoid vharafu), pamwe neyemagetsi kudzora system. Aya mutsauko wekugadzira anotendera iyo electro-hydraulic booster kugadzirisa simba zvichienderana nekumhanya kwemuchina. Izvi zvinoita kutyaira kwakachengeteka uye kwakachengeteka chero kumhanya.

Sega, tinoona iko kusununguka kwekufambisa pane yakaderera kumhanya, isingasvikike kune yakajairwa simba mudhiraivho. Pakumhanya kwakakwirira, iyo pfuma inoderedzwa, iyo inobvumira mutyairi kudzora mota zvakanyatsonaka.

Kubatsira uye kuipa

Kutanga, nezve zvakanakira EGUR:

• compact design;
• kutyaira kunyaradza;
• kushanda kana injini yadzimwa / isiri kumhanya;
• kurerukirwa kwekufambisa pane yakaderera kumhanya;
• chaiyo kudzora pakakwirira kumhanya;
• kushanda zvakanaka, kuderedzwa kwemafuta (kutendeuka nguva yakakodzera).

payakaipira:

• njodzi yekukundikana kweEGUR nekuda kwekunonoka kwemavhiri ari munzvimbo yakanyanyisa kwenguva yakareba (kupisa mafuta);
• yakaderedzwa sitiroko ruzivo rwezvinyorwa zviripo pakumhanya kwakanyanya;
• mutengo wakakwirira.

Servotronic chiratidzo che AM General Corp. EGUR Servotronic inogona kuwanikwa pamotokari dzemakambani akadai se: BMW, Audi, Volkswagen, Volvo, Seat, Porsche. Servotronic electro-hydraulic simba rinotungamira pasina mubvunzo rinoita kuti hupenyu huve nyore kumutyairi, zvichiita kuti kutyaira kuve nyore uye kwakachengeteka.
