efferman

it has front wheel drive. Grohl you made a great work again

sorry if my english is not enough, but is your post in the correct thread? edit If it is in the correct thread iknow which part do you mean, but i think this part is nothing for me

you was right. the torque is more than enough pleas correct me if iam wrong, but i think it performs great. no gearcrushing, only the MiniLA makes a nois if it runs at its end

could a big lego cylinder corrode? is it better to use olive oil or silicon oil to prevent the corrosion? if corrosion is not a problem, the ydraulik is a really genius solution for multiaxle steering. But for a excavator or similar it has in my humbly opinion no sense. i think i try a hydraulik suspension on my willys to get a proper axle load balancing

sorry i have must overread it.

there is a problem. pneumatics doesnt bring the Air back to the tank. so you must put the valves "in" the Tank, to get no fluid on the table. Long ago i had tried it in the bathroom with a big pump, one cylinder and one valve. it works, but why using water when the hose jumps from the fitting?

i will have both gears. in the vid i have tested a two speed gearbox, which could switched remoted. The axle bending is caused by a temporary fixation. maybe i will use a pneumatic suspension. but first i must build the body to see how much space i have. i think with the low gear i have enough torque. to answer your tire question please klick here edit: i have mounted a big part of the body, to see where i have spce for the gearbox and the other things. i hope you can imagine now the final sizes

very, very, very cool

sorry for the doublepost, but i have made a little Vid with the different Gear Ratios the first ratio is fast, but the xl sounds a bit stressed when it climbs the wall. the second ratio has in my humbly opinion a good speed for heavy terrain.

anyone must be the first, and iam sure that is anybody out there, who was faster than me. We doesnt only see it yet currently iam working on the 2 speed transmission, and i think it goes to be a hard nut.

looks good. on the first view i have only one hint for you. Dont pull a rope over a sharp edge (at the end of the boom)

at amazon de it is listed for 110€. release date is the fith march

sam, your picture says the truth. zblj, every lego gear can break. we will se if this jeep will become a new gear crusher. edit: i love the Mini LAs. with them i could build a really compact steering system. i build it at both axles and it works pretty smooth

the circumference of my tires (diameter ca 102mm) is, rolled up on the ground, 320mm per round. the xl have 220rpm at 9V at 1:6 this result in 36.66rpm of the tire 36.66 rpm x 320 mm = 195.55 mm per second at 1:21 i will have 54,67mm per second is my calculation false? the new cv joints seems to be a nice part but currently nothing for me

1:6? this would result with my tires in 190mm per second. sounds like a racecar and a little bit to fast for rockclimbing. maybe i will add a 2speed gearbox i love the unimog chassis. much more simple than a live axle, but nearly the same flexibility. and it works on small models

currently is planned a XL. i know, it sounds slow, but i think it is fast enough. if my way of thinking is correct, it will drive roundabout 3 meters per minute

good evening After a lot of thinking i have made my decission. it will be a Willys Unimog Hybrid. The chassis is inspired by a unimog and the body will be hopefully easiely to identificate as a willys. This is the current standing (Brickshelf folder) I have made two steerable portal axles, to let me the way open to get a 4x4x4. but maybe i will block the rear steering. the possbile lacing bond is huge, but the final model will not have the full way. I dont want destroy the willys look with a to high ground clearance. The final gear ratio is currently 1:21.459 and it seems i have find a good compromise between speed and climbing ability. the naked chassis, which you can see on the pics, have no problems with a 45° ascending slope. i hope the final performance is nearly the same.

your imagination is awesome

do you seriously think that a part like this will come? i think the unimog will have a double wishbone suspension. but anyway , i dont want wait 8 months

good questioncurrently i think about two possibilities: like original: no gear reduction but differential, drumbrake design and flat spring design. trial: portal axles on a unimog chassis, one PF-xl per each side, to simmulate a differential, not to make skid stear possible. with one word: extreme damn, i could me not decide

allan i will try to bring your system in my preferred dimensions

using a u-joint is possible but i want a high gear reduction which i could use for future projects. and they will become much heavier. the 14 tooth jumps over when it has to much load. i hope this will prevent a breaking of the 14 tooth. i will see how it works and if it not work.......

no, competition is not the goal, it has the wrong scale. if it goes over my rock crawling parcour, which you could see in my vids, i will be very happy. but it is no need

I believe you and i will look at an other solution

then you are a better designer than me. my had killed four 8 tooth gears at the same time during only 10 minutes driving.
