[TC6] Citroën Activa
5imon posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This will (hopefully) be my entry for the TC6 contest. Seeing all the great models already under construction (or almost finished), I don't see a lot of chances as a newbie, and I was thinking of withdrawing. So I thought it's a good idea to start a topic here and get me some peer pressure to finish ;-) As a big Citorën lover, the idea to build one of my favourite cars for this contest came quickly. But which vehicle would incorporate 4 independent PF functions? My choice was the Activa concept car from 1988: Shown at the 1988 Paris Motor Show, it showcased the electronically steered hydropneumatic suspension that was to show up the following year in the Citroën XM. Furthermore, it featured active anti-roll, four wheel drive and drive-by-wire four wheel steering with different modes, including crab steering. More info on http://www.citroenet...iva/activa.html The steering and suspension being the most interesting part for a Lego model, I chose the following 4 functions: _ driving (L-motor) _ front steering (servo) _ rear steering (servo) _ ride height (2 servos). I already finished the prototype of an axle (the two axles, having the same functionality, will be very similar; only difference will be that the front axle will include also the driving motor. Ride heights: The height adjustment mechanism was a bit of a challenge, as it has to move quite some weight on a small lever. It took me some time to brace the whole mechanism correctly. The next big challenge will now be to put the two axles in a strong enough chassis. The most difficult part however are the smooth, rounded lines of the Activa's body. I'm more at ease with mechanisms than with shapes, so let's see how I'll be doing... Comments and tips appreciated!
