Silinda birki - ayyuka, iri, fasali
Birki Silinda shine sunan gaba ɗaya don sarrafawa da masu kunna tsarin birki na motocin da ake tuƙa da ruwa.Akwai na'urori guda biyu waɗanda suka bambanta a ƙira da manufa:
• Babban Silinda (GTZ);
• Dabarun (aiki) birki na silinda.
GTZ shine sashin kula da tsarin birki gabaɗaya, wheel cylinders sune masu kunnawa waɗanda ke kunna birki ɗin dabaran kai tsaye.
GTZ yana magance matsaloli da yawa:
• Juya ƙarfin injina daga fedar birki zuwa matsa lamba na ruwa mai aiki, wanda ya isa ya fitar da masu kunnawa;
• Tabbatar da madaidaicin matakin ruwa mai aiki a cikin tsarin;
• Tsayar da aikin birki idan an rasa maƙarƙashiya, leaks da sauran yanayi;
• Gudanar da tuƙi (tare da ƙarar birki).
Silinda na bayi suna da aikin maɓalli ɗaya - tuƙi na birki na dabaran lokacin birki abin hawa.Har ila yau, waɗannan abubuwan da aka gyara suna ba da wani ɓangare na dawowar GTZ zuwa matsayinsa na asali lokacin da aka saki motar.
