I just had a question...has anyone here been able to successfully build a limited slip differential (LSD) or automatic locking differential out of the Technic elements? I've been toying around with the various types of differential designs used in (...) (23 years ago, 14-Apr-01, to lugnet.technic)

I have managed to make a LSD using the white clutch gear (clutch-pack type of LSD). Sorry, no pics yet! My original plan was to make a torsen type LSD, but after learning how one works, I have concluded that it's impossible to do with lego parts. (...) (23 years ago, 14-Apr-01, to lugnet.technic)

(...) Curious, what do MLD and ALD mean? BTW I took some quick pics of my clutch-pack LSD (installed in my McLaren F1). Two views of the engine bay are here (I removed the spoiler and opened the hatch): (URL) LSD is near the bottom of the pictures, (...) (23 years ago, 16-Apr-01, to lugnet.technic)

(...) It works extremely well actually. It is easy to push the car when it is going straight, but as you turn the steering wheel, you can feel the gradual tug of the LSD working as the car goes into a tighter turn. On grippy surfaces like linolium (...) (23 years ago, 16-Apr-01, to lugnet.technic)

(...) Shouldn't that be understeer? If the inner wheel is provideing a force, surely that would cause the nose of the car to veer outwards rather than inwards. Steve (23 years ago, 16-Apr-01, to lugnet.technic)

Hello, I have built both LSD and manual locking diff. Both were simple AND worked very well, BUT they are not realistic; I mean that they do not work the way the real LSD and locking diff. work. I'm still working on that... One of my creations is a (...) (23 years ago, 16-Apr-01, to lugnet.technic)

I wish I knew how to have the differential automatically engage the lock, but I can only think of ways that involve hydraulics... //Henry Chea hchea@kungstorget.nu *S* Göteborg, jaja, jag behöver inget mer!

(...) In the case of a RWD car with a *stiff* LSD in the rear, the inner wheel is always slipping a little bit whether on the throttle or brakes or nothing.. Considering that the highest amount of grip is typically at a 15% slip angle, it is not (...) (23 years ago, 16-Apr-01, to lugnet.technic)

(...) Nice design for the manual locking lsd. If you throw an adder-subtractor in there, then you would only need one rotation sensor. The drawback would be added friction in the drivetrain and space. //Henry Chea hchea@kungstorget.nu *S* Göteborg, (...) (23 years ago, 21-Apr-01, to lugnet.technic)
