Share some less-known information about cold war period tracked vehicle transmission
 


Mithubishi transmission MT75 for STB, later known as Type 74.
The basic layout of MT75 is similar to the CD-500 transmission on M41 light tank, used by JGSDF in a short period after war.
But the Japanese tank designers prefer mechanical gearbox rather than hydramatic gearbox, they use a electro-mechanic high-low range instead of a torque converter. The high-low range part is described as "１次変速"(range first stage).
The steering mechanism is a single-radius, double differential type, operated by engaging steering clutch, also resemble the CD-500.

Allison X-700 transmission, a 800-hp class transmission to replace XTG-411 on T95 medium tank in 1960s. 
Trials were successful but finally never adopted. The Army decided to develop a 1500-hp class transmission for XM803. 
X-700 then evolved into X-1100 transmission. The X-200 and X-300 were basically smaller variants of X-700. 
X-1100 users: M1 and its variants; Korean K9 "Thunder"; Turkish T-155 "Firtina"
X-300 users: Warrior IFV; CV90 series
X-200 users: M113 upgrade (A2 standard)
 
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
 


Allison XHM-1500-B2, a hydrostatic-mechanical transmission developed in early 1970s. A competitor against X-1100 but less successful. 
Different parts were shown in different color. 
Orange: power input and forward-reverse shifting mechanism;
Blue: hydrostatic-mechanical speed range (mechanical planetary gears were not shown in cutaway);
Red: hydrostatic differential steering system; 
Green: output shaft and planetary gears. 
 
 
Hope you enjoy these pics.

Waffentrager YOU FAKE BULLSXXT and FXXK OFF

In case you guys here cannot read Japanese:
It says "Height of lens assembly is about 380 mm"
May be taken from a manual of digital camera or sth. else. 
 
 

Guys, it's not over yet. 

And yes, I do have the original file, but for some obvious reasons I add some watermarks. 
 
Waffentrager is doing the same thing as he did on Warthunder forum. 
He is just bluffing with unknown source screenshots or photoshopped fake “documents”.
He deleted every post arguing the pictures' authenticity to make himself “invulnurable”.
