42056 - Porsche Speculation
nicjasno replied to Jim's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The real thing has a macpherson strut front suspension. -

If you use normal (existing) 12t thin bevel gears in combination with the axle hole on the diff, you put a bar through them (think: lightsaber bar) and you get a lsd. -

Orange would be great. I just hope the rear suspension is a bit more sophisticated than that. Also, that diff idea is great. and a 3L bar connects the small gears, and acts like a LSD with some friction. -

This could all be done with a servo motor and switches. Why go through all the trouble of making it mechanical? -

I really hope for 8880 style cv joints. -

Nowdays even a row of 3 can be replaced with panels. And regarding the construction of the whole car, the 5x7 box liftarm sections and other large pieces should be used to increase chasis strength and reduce part count to a minimum. I vote for Blue or Yellow. -

Absolutely, but a row of 5 liftarms makes no sense and can be easily replaced with panels. -

Should be more panels, less liftarms. Liftarms just add weight. -

Looks like the standard hub, 2 balljoint pins on each side to connect the wishbones, which are connected with 5L thin liftarms (already excludes a SLA setup) so they can mount a spring to the lower wishbone. I'll be happy if they manage to suprise me, but i doubt this will be the case, Looks very much like the setup already seen in the le mans racer (which is itself a variant of the same double wishbone setup lego uses since 1988). -

I had high hopes for this model at first. Then i saw the side view of the front wheel and saw the garbage wheel hubs with garbage cv joints and a bog standard lego double wishbone setup. Looks like the wheels have at least the proper offset and more room for suspension stuff inside of them. i was really hoping for new hubs with 8880 style cv joints and at least some caster (or a macpherson setup like in the real thing). -
Creating a model in the first place and making a replica are two completly different things.

I'm kinda certain that he saw it live at the toy fair, made some reference pics and made it at home.

Have we seen this yet? A replica that looks to be just like the real one. http://www.brickshel...ry.cgi?f=553969

Red Dakar rally car
nicjasno replied to Samolot's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Your steering rods need to be paralel to the suspension arms, not straight like they are now. The amount of bump steer this generates must be enormous. edit: i see that is the rer of the car i was looking at, but i still don't get why you have the 9L steering links there, since it doesn't look to be a multilink setup. -
On the finalgear car forum we made a nice thread about the oomphines of our rides: https://forums.finalgear.com/general-automotive/forum-wide-survey-how-oomphy-is-your-ride-59181/

Ok... torque is then F x r i guess. So i need to measure the force a pneumatic piston produces somehow.

How could i measure the power of my pneumatic engines?

Rack and pinion is used in the new volvo trucks with independent front suspension. Live axle trucks all use one form of recirculating ball steering box with linkages.
