nicjasno Posted January 18, 2014 Posted January 18, 2014 (edited) As discussed in This topic, i had an idea for the ultimate wheel hub. At the same time, lego also needs new wheels. And while we're at it, why not add some more features, like a disc brake :) The hub itself also has provisions to use the bionicle ball joints as steering and suspension links. The wheel itself has the same width and diameter (including tire) as the 8110 unimog wheels and is finally a low profile design with a big inset to allow us the freedom to design any suspension type we want. So i employed my good friend IceBone, who some may also know from my videos, to help me put the design i had in my head into digital form: Edited January 18, 2014 by nicjasno Quote
unimog123 Posted January 18, 2014 Posted January 18, 2014 Sounds like a great idea, although I'm not familiar with Bionicles. What would you use to transfer drive or would you need a new piece as well? Quote
nicjasno Posted January 18, 2014 Author Posted January 18, 2014 The drive is done with the 8880 CV joint piece of course. Quote
Seasider Posted January 18, 2014 Posted January 18, 2014 Sign me up. How do we convince lego to make these parts ? Quote
unimog123 Posted January 18, 2014 Posted January 18, 2014 Oh, I guess that would make sense. Unfortunately I don't have that set, so I wouldn't really understand. Thanks. Quote
tibivi Posted January 18, 2014 Posted January 18, 2014 Wow, i would definately buy that (in bulk ) :p Good job Quote
Conchas Posted January 18, 2014 Posted January 18, 2014 I like the wheel offset, like in many RC cars. But a new element for a decorative disc brake, doesn't seem much inline with the discussion going in the original topic. Quote
cgg199 Posted January 18, 2014 Posted January 18, 2014 To me, it looks like the disc brake could be used as a real disc brake as the wheel has a big enough inset to allow it, whilst the hub could support the linkage. Quote
nicjasno Posted January 18, 2014 Author Posted January 18, 2014 Sign me up. How do we convince lego to make these parts ? No idea. Keep in mind, that this is just a rough prototype. But i have designed it with compatibility in mind. It can be mounted silver champion rims, to 42000 rims but not the unimog rims, because they're just too damn small. Bionicle ball joints can be mounted on all 4 corners of course, as can be normal connectors for the normal small balljoints. With this you can also make ALL suspenion setups. Double wishbone, macpherson, multilink front and rear and even live axle designs. I wanted to make it 5 studs high, but there would not have been room for balljoints in multilink setups. The rims have also been designed to not only be very deep. One of the main goals was also to not repeat the mistakes made in the 8448 rim design, which was instantly dated and doesn't really fit any model and can't be mounted to the wheel hubs. I like the wheel offset, like in many RC cars. But a new element for a decorative disc brake, doesn't seem much inline with the discussion going in the original topic. That disc is not for decorative purposes. The render just lacks the pneumatic brake calipers. To me, it looks like the disc brake could be used as a real disc brake as the wheel has a big enough inset to allow it, whilst the hub could support the linkage. Precisely. Quote
cgg199 Posted January 18, 2014 Posted January 18, 2014 (edited) Anyway, I really like the design and think it'd be very useful for super cars. The wheel design is also quite modern and 'cool', as well as looking more like a real wheel than TLG's designs. Have you thought about anything like this on a smaller scale?

It fits with the new sleek panel design. Well, i'm sure the small wheel hubs have a lot of potential. But no. Haven't considered a smaller scale. This system was designed to allow people to make real super cars. All other things are there. The only thing that has been REALLY lacking all along was this. A proper wheel and proper multipurpose wheel hubs. Quote
cgg199 Posted January 18, 2014 Posted January 18, 2014 I agree, this was definitely more important than a smaller design. I also like how this hub can be used for very simple designs swell, similar to current Lego suspension, but it has the potential to do much more. I just wondered about smaller scale because I'm currently designing a car with the 43.2x26 wheels, but I'm trying to implement some advanced suspension geometries, however it's very hard and, I have no clue if it will really work. I think that the 2014 suspension parts will be useful for this sort of design though. Quote
JGW3000 Posted January 18, 2014 Posted January 18, 2014 Makerbot, here we come! This would be an ideal crowd-sourcing project, there is a Makerbot store about an hour from me, could get some prototypes made up in ABS? Quote
nicjasno Posted January 18, 2014 Author Posted January 18, 2014 (edited) Great job Hmm Shapeways? I'm not sure those parts would be 3d printable. The tolerances are just too small and precise. They do need to be injection molded. And lego are the only ones capable of doing that. Edited January 18, 2014 by nicjasno Quote
aol000xw Posted January 18, 2014 Posted January 18, 2014 Not asking about the soft, asking if you will upload the models to http://www.shapeways.com/ That way we could get 3d printed in plastic or even steel. Quote
nicjasno Posted January 18, 2014 Author Posted January 18, 2014 Maybe. it still needs some work. Quote
erix Posted January 18, 2014 Posted January 18, 2014 I use this company all the time for work: www.protomold.com Upload your solid model and it will return a tooling price, part price, and mold analysis. This will be an expensive tool, multiple slide outs cost a lot to engineer and that flange on the back might need to be tweaked. Still it is a way to get tooled parts to the masses.... Quote
cgg199 Posted January 18, 2014 Posted January 18, 2014 Is there any way to add a ball joint mount, or something that can be used as one? I've been looking at the wheel hub and can't think of a solution that would keep the pivot point inline with the CV joint. Quote
piterx Posted January 18, 2014 Posted January 18, 2014 it would be awesome making something to drive the front wheels while using the small double wishbone... do you think you can design something for that too :P? Quote
cgg199 Posted January 18, 2014 Posted January 18, 2014 it would be awesome making something to drive the front wheels while using the small double wishbone... do you think you can design something for that too :P? If you used the new Lego wishbone, that would be quite easy. You could use Macpherson Strut suspension or just implement kingpin inclination into the design. Quote
HorcikDesigns Posted January 18, 2014 Posted January 18, 2014 This one might solve many problems with front axles. However, the wheel is just for supercars and not for offroads ;) I like the idea of new HUB and wheels, but I don't like the new wheel's design. Quote
piterx Posted January 18, 2014 Posted January 18, 2014 If you used the new Lego wishbone, that would be quite easy. You could use Macpherson Strut suspension or just implement kingpin inclination into the design. no dude i want something not longer than the regular grey wishbone so i can connect it to the diff :) Quote
DrJB Posted January 18, 2014 Posted January 18, 2014 (edited) All of these concepts, while very interesting/promising, are nothing but 'dreams'. I highly doubt that TLG will ever consider such designs, given their recent move to Cuusoo rules changes etc. Also, the spherical/ribbed ball (that goes into the 4x propeller blade or 8880 hub) has not been seen in a long time, and I highly doubt we'll see them again. Many of the new parts in recent years are (the way I see it) an attempt to go to even smaller parts, be it the suspension arm, cardan, or the plethora of non-technic parts. Maybe the ultimate target is people with small fingers, and who are easily impressed by the high part count advertised on lego sets. Not meaning to sound negative but ... all you need to do is look at all the parts proposed by Cachon ... That said, I'd love to be proved wrong. Edited January 19, 2014 by DrJB Quote
