| Does anyone have designs for a suspension setup using the dark gray shock absorbers? I would like it to have a lot of travel, and have the axle drive the wheel. (I'm building a sort of space rover. So far I've built one wheel (about 13 studs in (...) (24 years ago, 10-Aug-00, to lugnet.technic, lugnet.build)

| (...) Are you building your own wheels? Cool! I suppose you can't get a round perimeter? Regarding your question: What kind of suspension do you want? Independent or live axle? Do you want drive or steering? The latter will make your quest more (...) (24 years ago, 10-Aug-00, to lugnet.technic, lugnet.build)

It is similar to (...) (24 years ago, 10-Aug-00, to lugnet.technic, lugnet.build)

It's about 6 studs wide where it's in contact with the ground and 8 studs in the center. I expect it'll work best on carpet. (...) (24 years ago, 10-Aug-00, to lugnet.technic, lugnet.build)

I'm not ;) Instead I built a somewhat similar system: basically two (...) (24 years ago, 10-Aug-00, to lugnet.technic, lugnet.build)

Thanks to a worm gear, the vehicle moves slowly but steadily. The fact that the (...) (24 years ago, 11-Aug-00, to lugnet.technic, lugnet.build)

| (...) Ah, yes! A custom made independent suspension, much like the one on 8448 or 8865. This approach will need no less than four universal joints. I think that it prevents the width of the vehicle from being narrow, so I've never used this approach (...) (24 years ago, 11-Aug-00, to lugnet.technic, lugnet.build)

And keeping the differential fixed makes the rest of the (...) (24 years ago, 11-Aug-00, to lugnet.technic, lugnet.build)

| (...) You are certainly correct about this, but as the travel of the suspension is relatively short, the effect is not a problem. The setup really is very smooth. By the way, I've changed the menu on the page now, and added some 'vintage' models (...) (24 years ago, 12-Aug-00, to lugnet.technic, lugnet.build)

| (...) The 'geometric incorrectness' (!) is also true for the driveshafts of course, as the wheels have a fixed distance between them even though the driveshafts change angle. This is not a problem as this design allows the springs to be mounted in (...) (24 years ago, 13-Aug-00, to lugnet.technic, lugnet.build)
