Silinda na birki: tushen tsarin birki na motar ku

tsilindr_tormoznoj_1

A cikin motocin da ke da tsarin birki na na'ura mai aiki da karfin ruwa, manyan silinda na birki na wheel suna taka muhimmiyar rawa.Karanta game da abin da silinda birki yake, wane nau'in silinda ke akwai, yadda aka tsara su da aiki, da kuma zaɓi daidai, kulawa da gyara waɗannan sassa a cikin labarin.

 

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.

Lamba da wuri na silinda ya dogara da nau'in mota da adadin axles.Babban silinda na birki ɗaya ne, amma sassa da yawa.Yawan silinda masu aiki na iya zama daidai da adadin ƙafafun, sau biyu ko sau uku (lokacin shigar da silinda biyu ko uku akan dabaran).

Haɗin birki na dabaran zuwa GTZ ya dogara da nau'in tuƙin abin hawa.

A cikin ababen hawa na baya:

• kewayawa na farko - ƙafafun gaba;
• Da'irar ta biyu ita ce ƙafafun baya.

Babban birki na silinda an kasu kashi biyu bisa ga adadin da'irori (sashe):

• Single-kewaye;
