Mugen bulldog airshock dissection

Mugen Bulldog sold in 1985 said it has this special air shock. It was preassembled and can't be opened for service. Now I have one to dissect and open up. An interesting coil, o-ring on the piston, seriously nothing more than just a friction damper

冇乜巧妙，只係作為一個氣閥，畀D valvular resistance

明白了，謝謝你呢。

係呀師兄。為咗工房眾師兄弟，又為咗科學發展，唯有犠生小小避震

由於上手拆哂，我又未放返兩粒新嘅落去。我諗極都唔明扭粒螺絲入去同氣壓有什麼關係，有否前輩能賜教？謝謝 ...

我最近入咗 bulldog 2，睇返 manual，支 air shock 用粒機米螺絲去調氣壓...

good good

其实呢隻氣壓避震係ok 嘅。緩沖可以ok較，但因為內置彈簧關系就冇得調彈力。

按這道理，是否所有無入油的油壓都叫airshock？

完全唔同架，

I wondered how it worked for many years, thank you for solving the mystery

Man... I had one of those... Went to 麼頓台 all the time back then..... Faster then all other hotshot/Optima etc... Car was fast...I even ran it with those 1/8 Serpent back then,,, . But hard to get parts...(興記 there....)

入面當然有空氣而非真空
而活塞活動時亦會有氣體被壓缩
但係同條彈弓彈力/回彈力比較可能同Tamiya無油膠避 ...

又唔係喎，佢真係有吸震效果架，我漏氣果支就同無油油壓一樣跳跳下喇！

多謝師兄解讀多年的問題！我以為連彈弓都冇！謝謝.

去年在倉底, 找到了一對全新!

按首頁的縮圖入來以為是無刷摩打心原來是古時的避震

好假既氣壓避震,原來裡面"裝彈弓", 真係好有CY feel, 無限:我冇講過我冇裝彈弓

你解答了我心裡30年的疑問！
原來入面咁簡單

起碼唔會好似啲油壓咁漏油

that was why I bought Bulldog but the airshock did not work well at all...
