Flexichas Motor Bogies.

Flexchas Motor Bogies : Been thinking for quite some time about modelling a couple of motor bogies with Sharman type suspension and although the idea I have in mind is new to me, I wouldn't be overly surprised if the idea had already been done. Some years ago, scale flange wheels were fitted to all snitzl rolling stock, which in turn made all of the fixed chassis locos unreliable due to derailing. Presently, with the exception of two motor bogies, all rolling stock has been modified to include the sharman type suspension system.

This new motor bogie project will be modelled as if by a deveopment engineer, components will be made from scratch, assembled and modified as required, to overcome the unforseen problems that will probably arise due to lack of initial design input. Starting point for the project will be to construct two enclosed gear box's as described in the "Gearbox Madness" blog, one of these will be fixed to a chassis, while the second is allowed to rotate about the worm shaft. The worm shaft will require some support at one end of the bogie by some sort of bearing and we also need to attach outer frames to the main chassis. Motor will be mounted above the worm shaft and drive transmission will be through spur gears. A second bogie, although of similar design to the first, will have much smaller worm and wheels due to the small diameter of the driving  wheels. Lets see how things progress.
