Help needed whit my moc.

[legolijntje]

Hello,

I'm working on a moc, based on a Liebherr LR 634. It's crawler loader.

The problem (you can see it on the photos): I want to put 2 m-motors at the left side of the baterry box (I hate that shape, i'm goning to buy the other one, but I have no time to wait for it), to drive the 3 linear actuators (you can see them on the picture of the real thing). The LA's have to begin above the drive-motors. But I don't now a solution to motorize the 3 LA's, whit the 2 motors above each other. Does someone now a solution?

I hope this explanation is clear.

The pictures (I have linked them, puttting them in the post did'nt worked?):

The real thing:

Hi legolijntje

I don't know if I understand you correctly but if you want to pass the lower motor's power to the top without affecting the upper motor I suggest you to use 16 tooth gears and this 16 tooth clutch gear to put on the axle of the upper motor.

It has no crossholes so it can spin freely.

Hi,

As I have the 8043 model-b built here on my desk, why not use it as your starting point?

It looks a lot like the MOC and it just lacks the back-part claw.

Thanks,

Noam

Yes, I can use the B-model for some help, but the real problem is mostly the 2 motors above each other.

Looking at wip3.jpg, here's my suggestion:

If you have the room, move the upper motor up 1 hole from where it is. Leave the 16t gear on the lower motor, put a 16t idler gear above that, then put a 16t clutch gear on the output shaft of the upper motor, which will then mesh with the upper 16t gear.

Apart from that, are you having issues with the chain drive setup you've got mocked up in wip3.jpg? If the chain is jumping teeth on the gears, it's possible that adding the clutch gear to the upper motor would help with that.

hope one of these helps you

i added a extra gear on the first one by mistake sorry

Or you can always use a 16 tooth gear without X shaped hole, and route power over the upper M motor.

First I had a clutch gear between them, but then it made a strange noise. It did'nt sound good.

What you said about you idea; I will try it tomorrow.

Sorry, but the first solution; I have no space for that 12(?) axle.

The second picture; I have no space for the 2 motors next to each other. (or I have to redisign everything)

you dont need to use the 12 axle that was just what i put in
