Kapangidwe ka vacuum booster.
Cholimbikitsira vacuum chimapangidwa makamaka ndi pisitoni, diaphragm, kasupe wobwerera, ndodo yokakamiza ndi joystick, valavu yowunikira, valavu ya mpweya ndi plunger (valavu yochotsera vacuum), ndi zina zotero. Mtunduwu ndi wa mtundu umodzi wa diaphragm vacuum suspension.
Mfundo yogwirira ntchito ya vacuum booster
1, pampu yolimbikitsira mabuleki imagwiritsa ntchito mfundo yopumira mpweya injini ikugwira ntchito, zomwe zimapangitsa kuti pakhale vacuum mbali imodzi ya chilimbikitso, zomwe zimapangitsa kuti pakhale kusiyana kwa kuthamanga poyerekeza ndi kuthamanga kwa mpweya komwe kumakhala mbali inayo, ndikugwiritsa ntchito kusiyana kwa kuthamanga kumeneku kuti kulimbitse kuthamanga kwa mabuleki. Ngakhale pali kusiyana kochepa kwa kuthamanga pakati pa mbali ziwiri za diaphragm, chifukwa cha malo akuluakulu a diaphragm, kuthamanga kwakukulu kumatha kupangidwa kuti kukankhire diaphragm kumapeto kwa kuthamanga kochepa.
2, pamene ntchito ikugwira ntchito, kasupe wobwerera wa ndodo yokankhira umapangitsa kuti brake pedal ikhale pamalo oyamba, panthawiyi, chubu cha vacuum ndi malo olumikizirana a vacuum booster a valavu yowunikira ali otseguka, mkati mwa chilimbikitso, diaphragm imagawidwa m'chipinda chenicheni cha mpweya ndi chipinda chogwiritsira ntchito, zipinda ziwirizi zimatha kulumikizidwa wina ndi mnzake, nthawi zambiri zonse zimakhala zolekanitsidwa ndi dziko lakunja, Pokhala ndi zida ziwiri za valavu, chipinda cha mpweya chimatha kulumikizidwa ndi mlengalenga;
3. Injini ikayamba kugwira ntchito, yendani pa pedal ya brake, pansi pa ntchito ya push rod, vacuum valve imatsekedwa, nthawi yomweyo, valavu ya mpweya yomwe ili kumapeto ena a push rod imatsegulidwa, ndipo mpweya ukalowa (chifukwa choponda pedal ya brake kuti upange phokoso lopuma), umayambitsa kupanikizika kwa mpweya m'chipindamo. Pansi pa mphamvu yoipa, diaphragm imakokedwa kumapeto kwa brake master pump, kenako imayendetsa push rod ya brake master pump. Izi zimawonjezera mphamvu ya miyendo.
Kodi chimachitika n’chiyani ngati vacuum booster ikutuluka?
