Small front independent suspension with drive

[gsia17]

Hi!

Soon, I'll show to you new little rally car with rear independent suspension and rear drive. But rally car must be AWD, so I build small front suspension

*cardan has free lift under load without stoppes

I'm going to build audi quattro or toyota celica with this system. May be you have another ideas for it?

[piterx]

that's great man!

you can build a thousand vehicles with that system :)

Impressive. I eagerly await a vehicle with this setup.

WOW, great! Brand new Base for small awd cars;)

Thanks!

I too..

P.s.I'm waiting for one question so answer it now: "Why i don't use efferman system(http://www.eurobricks.com/forum/index.php?showtopic=60459&st=1375#entry1895722) or sth like that?"

Firstly, I can't use little wheels with new steering portal. Secondly, clearance very small with this portal.

P.p.s I use unusual wheels

Finally a way to make small realistic 4wd cars! Great job! Looking forward to rally car, possibly a kind of hatchback style so you could fit an interior and still have room for battery box.

Brilliant creation. How will your steering work with a servo? Servo is probably a bit large for your model anyway.

Fantastic!! I've been trying to come up with something like this for ages......

A small compact suspension without all the fancy linkage pieces (that I wish I had ).

[Nazgarot]

I love it. Great solutions to save width, and nice out of the box thinking!

impressive :) I wonder if this is possible with 80-90s technic parts only. One question that I have, how it is working in real without the differential?

You gave me an idea which I will try to test, thanks.

Wow, that's ingenious!

[Hrafn]

This is brilliant, thank you for sharing it! I'm totally going to use this for an AWD rally car of my own.

[gsia17]

Thanks you a lot!

If somebody will build it, using silicone grease in shock absorber. It will start work better

Yes, servo is quite big, also it turns 90 degrees, and it is too much

I have a car with rear suspension and drive like this. It work not bad, so I hope this system will work ok too.

Sweet as a nut....

Clever idea for using the spring out of a lego shock over an axle, saves space, is linear and is very useful not just in cars but in mechanisms themselves.

[Hrafn]

One question - have you considered using instead of , and using a 20t single-bevel gear to drive the axle? That way you could get the center of the U-joint lined up with prop shaft axle, and both half-shafts would be of equal length.

EDIT: it wouldn't quite line up, but it would get you 1/2 a stud closer to lining up.

Reminds me of the twin I-beam suspension found on the older Ford vehicles.

Movement is so small, that it doesn't matter. Also I prefer use 12t gears because that i can use buggy motor directly without additional gear.

P.s. I start build Toyota Celica.

Hi I was wondering if I can use this system and your other rear suspension one of my projects. All of the credits will go to you Gsia17.

Thanks in advance.

[miguev]

I plan to do that, with due credit of course, even if I end up modifying it. I noticed this video on YouTube months ago and already tried both RWD and AWD, together with the small rear setup and a buggy motor.

Problems I found so far:

1. RWD can't steer, I guess due to the lack of differential

2. When going full speed backwards and the giving full throttle forward, the CV joints pop out of place. U joints resisted that, but the problem only really happened when forcing the RWD setup.

3. CV axles are too short and wheels eventually go away, I tried 4L axles with U joints and still had the same problem, so I think I'll uses 5.5L even though it will look ugly.

Other than that, this is a wonderful suspension setup and I hope you (gsia17) are fine with others reusing it :)

In any case, thank you so much for the inspiration you're giving us already!

Certainly use it! I will be happy if my ideas will find a place in your models. Hope you show me the result

Thanks! Yes, at the moment, I have not found the solution this problems, but as soon as a good idea come - I'll fix it.

Will you be making instructions? And this is amazing!

@gsia17:

Interesting Idea... thanx for sharing... :)
