- Ukubhuleka okusizayo okuphethwe kahle kungandisa impilo yesevisi yamabhuleki esisekelo kusukela cishe kumamayela angu-50,000–70,000 kuya kumamayela angu-200,000 noma ngaphezulu ekusebenzeni okunzima.
- Hlola amakamelo amabhuleki, izilungisi ze-slack, ama-caliper, ama-lining, ama-drum, ama-disc, kanye nezingxenye zesistimu yomoya njalo ngoba ukubhuleka okusizayo kuvikela kodwa akuthathi indawo yesistimu eyinhloko yamabhuleki.
imibuzo ejwayelekile ukubuzwa
Kusetshenziswa ini ukubhuleka okusizayo lapho kwehla isikhathi eside?
Ukubhuleka okusizayo kulawula isivinini semoto ngenjini, exhaust, noma driveline ngakho amabhuleki esisekelo ahlale epholile futhi elungele ukuma okuphuthumayo noma ukwehla kokugcina kwejubane.
Kungani abashayeli kufanele bagweme ukugibela amabhuleki esevisi ehla entabeni?
Ukusetshenziswa okuqhubekayo kwe-service-brake kungashisa kakhulu ama-drum noma ama-disc, okubangela ukufiphala kwama-brake, ukuguguleka kwe-lining okusheshayo, kanye nokulahlekelwa ukulawula imoto lapho yehla kakhulu.
Kungamazinga okushisa angakanani lapho ukufiphala kwamabhuleki kungaba yingozi enkulu?
Ukufiphala kwamabhuleki kungaqala lapho amazinga okushisa esigubhu edlula cishe ama-250°C (482°F), futhi ukushisa ngokweqile okungaphezu kwama-500°C (932°F) kungabangela umonakalo wengxenye noma ingozi yomlilo.
Ingabe ukubhuleka okusizayo kungathatha indawo yamabhuleki esisekelo ngokuphelele?
Cha. Amabhuleki asizayo awenzelwe ukulawula isivinini okuqhubekayo, kuyilapho amabhuleki ayisisekelo esadingeka ukuze kumiswe ngokushesha, kulawulwe isivinini esiphansi, kanye nokuma kokugcina.
Ukubhuleka okusizayo okufanele kunciphisa kanjani izindleko zokulungisa izimoto?
Ukusebenzisa i-assistant braking ngendlela efanele kungandisa impilo yamabhuleki esisekelo izikhathi eziningana, kunciphisa ukuphinda kusebenze, isikhathi sokungasebenzi, kanye nokuguguleka kwezingxenye ezifana namakamelo amabhuleki, ama-caliper, ama-pad, kanye nama-slack adjuster.
