Source: http://yuripasholok.livejournal.com/2825352.html Hello everyone, Yuri Pasholok posted something quite interesting not long ago – he demonstrated that the origins of the T-28 suspension actually started with… Krupp. Check this out. It is well known, that since Soviet Russia and Germany were allies before the war, German tanks were tested on a polygon near Kazan. These tests included the Grosstraktor prototoype vehicles (one of which was made by Krupp). Russian engineers of course weren’t blind and in the internal Russian correspondence, the T-28 suspension is referred to as “Krupp suspension”. To compare, this is the T-28 suspension: And this is the Krupp Grosstraktor, it’s “grandfather”: Yuri Pasholok states that the Russian engineers in this case copied only the suspension, but not some other details, such as the roadwheel design and as a result, T-28 – although stable – was not capable of going as fast on the road as the German design, a fact that is pointed out in the abovementioned correspondence.
