Fulfilling the decree of the Committee of Defense #428 from November 19th, 1940, I present my thoughts on the transition to torsion bars on the T-34.
The springs (candle) on the T-34 are reliable, but have the following drawbacks:
- The suspension shakes, which reduces the accuracy of fire on the move.
- The wells in which the springs are housed reduce the space inside the tank, which impedes the placement of components and reduces the ammunition capacity.
- In order to allow for movement of the vertical balancers, the side plates have cuts in them, which reduces the robustness of armour.
- A 20% increase in the volume of the fighting compartment.
- A reduction of the suspension weight by 300-400 kg.
- Increase in fuel capacity from 465 L to 750 L, increasing the range by 60-100 km.
- The hull robustness is increased (due to a lack of cuts).
- The reliability of torsion bars has been proven on the KV and T-40.
- Factory #183 has the means to make torsion bars.
