Indlela ePhambili yeSlack Adjuster

I-slack adjuster isebenza njenge-mechanical lever edlulisela amandla ukusuka kwi-brake camshaft ukuya kwi-brake. Umsebenzi wayo oyintloko kukubuyisela ukuguguleka kwe-friction linings ngokulungisa "i-slack" okanye ukudlala ngokukhululekileyo kwinkqubo. Njengoko i-brake linings iphela, umgama ekufuneka uhambe kwi-pushrod uyanda; i-slack adjuster isusa olu hambo lugqithisileyo ukuze igcine impendulo ye-braking ngokukhawuleza. Kwizicelo ezinzima, ukugcina olu xinzelelo oluchanekileyo kubalulekile ekuthinteleni ukuguguleka kwe-brake nokuqinisekisa ukuthotyelwa kwemithetho.

Umgaqo wokusebenza we-Drum Brake Slack Adjuster

Kwinkqubo yesiqhelo ye-S-cam drum brake, i-slack adjuster ifakwe kwi-slined camshaft. Xa uxinzelelo lomoya lungena kwigumbi le-brake, i-pushrod iyanwebeka, ijikeleze i-slack adjuster. Olu jikelezo lujika i-camshaft, nto leyo enyanzela izihlangu ze-brake ukuba zidlale kwi-drum. I-automatic slack adjuster (ASA) ngaphakathi kolu seto ijonga i-actuator stroke. Ukuba i-stroke idlula umda omiselweyo ngenxa yokuguguleka kwe-lining, i-giing yangaphakathi ye-ASA iyacofa kwindawo entsha, ijikeleze i-camshaft kancinci ukuze izihlangu zisondele kwi-drum.
