 | | Limited slip differential —Simon Bogaert
|
| | | Hello all! As I was tinkering with some of the new-style differentials, I discovered that the claw-clutches (used to couple a free-turning 16 teeth gear to an axle in the 8880 Supercar and in the Space Shuttle) can be used to let both output axles (...)

| | | | | Interesting. I assume you're talking about the white gear-looking thingy that comes with 8735. Where would you put it? In the center peg within the diff? - Greg (...) (24 years ago, 31-Aug-00, to lugnet.robotics)

| | | | | | (...) Actually, no. The white gear is known as the 'clutch gear'. It prevents the frying of your motor in case it gets stalled. I don't know any way you can prevent it from 'clutching' if the tension on the gear gets too high. What I actually meant (...) (24 years ago, 31-Aug-00, to lugnet.robotics)

| | | | | | Now I see it. I found the gear you were talking about on the Technica site. This if very serendipitous, as I have recently been pondering how to make a locking diff with Lego. Thanks for the intel! - Greg Simon Bogaert wrote: <snip> (...) (24 years ago, 2-Sep-00, to lugnet.robotics)

This is an excellent observation Simon, I had noticed that the bits on the the small gear on the differential were similar to that on the 16 tooth idler gears, but had never actually put 2 and 2 together and come up with the idea of using the (...)

To do this, first put together the differential with (...) (24 years ago, 2-Sep-00, to lugnet.robotics)

Time for the pedant to strike again - I think you are right in saying that this part serves a similar purpose to a synchro in a real car, but the real one gradually sychronises the speeds of the axle and the "idler" gear so that (...)
