6 axle with 2 motors ?

Interesting - I haven't put any thought into this yet, but my first reaction is - Why? What is the purpose?

I am not trying to dissuade you or anything - I am just curious. I have never really come across such a concept.

Loooong ago machine shops had the same problem.

One water wheel, steam or diesel primary driver with the need to have loads running intermittently. This they achieved with one or more drive shafts hanging from the ceiling with each tool that can be isolated with a clutch / removing the belt or . . .

The same principle would apply, you would need to disable / disconnect the drive between a motor and a shaft if one is running and one should be stationary.

I am very curious as to why.

The 144 is not enough as a clue.

Same question why ? why you want to drive the axles with 2 motors ?

I always am more comfortable driving them with single motor.

If two motors are on same shaft and are energised, you always have aload sharing problem.

use shifters/ gear/ pulleys form a single motor /individual axle motors to drive the axles as you want

The shifter logics/ RH/LH can be easily achieved by relays and simple electronics logic - either direction of rotation of the motors may be sensed or the signals to motor may be sensed to activate the required axle.

Assuming the voltage across terminals (being DC Motors) are as below

This is a simple logic and can be converted to activate shifter or if the cost/ power permit activate individual drive motors.

You have two motors with eight possible combinations, nine if you include both stopped, so possible a PLC unit or aux contact breakers to operate electric clutches, or engage a gear?

Looks like Fun!

Also looks like someone's homework.

Convince me it is not, I want to play with it.

mail me back with the aplication,use of those axles, i will send you a drawing sketch,showing,how to rotate different axles at different timing and rotations direction only with single motor tell me wat size and no of teeths ,n nos, of gears you have , do yu want it mechanicaly or electronicaly controlled..........manual changing lever, or automatic shifting.....

Mechanically, the use of six differentials (one per axle) and two inversions (1:1 gears) would suffice. But would this not be more complicated and expensive than using six DC motors?

This is not perfect as it relies on the least path of resistance to work and as drawn the shafts would rotate in different directions, but that is easy to solve.

Each motor drives the input pinion of a differential, with the output pinnions connected via a belt drive.

The green and red parts are "sprag clutches" which would connect to the shafts via belts. Green ones drive clockwise (C), red ones drive anti-clockwise (A).

2 pairs of clutches on each differential cage drive 4 shafts, 1 pair on the belt drive power the other 2.

Just an idea.

Hydraulic pumps on the motors, a valving system that detects the 6 conditions you specify, and routes the pressure appropriately.

Of course you don't say how much power or speed you need so all bets are off.

thank you all for your answear i will check your solutions :)

....and give us marks out of ten?

are you making a toy or somethin..........
