I'm still working in the sports car (which I think will be about 8-10 studs
longer and 4 wider than 8408... using the same wheels). The frame is almost
ready, and it will include 2-speed gearbox (if I can, I'll build a 3-speed
one and pop-up headlights) front independent suspension and maybe rear live
axle.....
Maybe because I have seen many lego suspension systems (from official sets
and MOCs)(and no-suspensions also)... and almost all of them have a
differential gear... almost because the 8840 doesn't have it... it only has
1-wheel-drive!!!!
(don't you believe me? check here:
http://library.brickshelf.com/scans/8000/8840/ )
So I've got some questions:
1) Are differentials so important when builiding cars? What would happen if
I don't use one?
2)I don't have any differential gear (If you want to know what do I have,
are these sets: 2854, 8207, 8216, 8226, 8232, 8236 and 8422; one each one)
Is it possible to build a working differential? and how without having to
make a 1wd car?
Thanks a lot
Luis

| hey! nice one! I didn't notice that there was a "1wd" car! (an "inverted" 1wd car, because the wheel drives the piston(s)) very funny, in my opinion! what you are searching for is here, anyway: (URL) Hernández <lmhariano@latinmail.com> wrote in (...) (22 years ago, 19-Dec-02, to lugnet.technic)

| hi! 1. differencial gear is needed to give an ability to rotate right and left wheel independantly when car's moving ahead there is no difference in speed of rotation left and right wheel but whe car's running on a curve every wheel is going to run (...)

| First of all 1wd car would be only one wheel running. But in the 8840 instructions both rear wheels are driving the engine and it is by definition a 2wheel drive car, but with a stiff rear axel. A true 1wd car would have only one wheel conected to (...) (22 years ago, 20-Dec-02, to lugnet.technic)
