mechanism in nested assemblies.

[320i S]

good day to all, I would like a help from the forum to better understand the constraints of mechanism, in nested assemblies for the distinct base.
I make a very simple example as "annidation":

1-"Hydraulic Cylinder" formed by stem and shirt (can be used in many other assemblies);
2-"pre-assembled hydraulic cylinder" which includes point 1 cylinder + control valves and fittings(can be used in many other assemblies);
3-" lifting group" composed of several structures and the pre-assembled point 2

what mechanism constraints do I have to give to the hydraulic cylinder because in all 3 cases, can with the manipulator move the cylinder for verification? (my current problem is about 3 level).
I exclude from this any flexible pipes.

Thank you.

Hi.

more than a problem of connections is a problem of organization of the project, the bond for the cylinder is fine a "course", but the "lifting group" must be bound only and exclusively to the mobile part of the piston, otherwise it blocks the whole mechanism.
If you study it well, maybe using a set of points in space, you could also insert the hoses.

Hello, thank you for the suggestion, I try.

I did some tests and I have to say that it is easier than I thought (a lot of complications I had to use with catia, here do not exist!).

the appetite vien eating though.

now I am with another passage:
I have 2 cylinders, they are contrasted (type boxer) and are connected together, i.e. how much pressure, to one to get it out (positive course), also comes out in a practically equal way.
the axieme is formed by central plate and cylinders fixed on the shirt side on it rigidly.
How could I make a mechanism that how much I move one of the two, moves the other too?
Do I have to go into the world of film skeletons?

Do I have to go into the world of film skeletons?

No, no, that's why there's an extremely simple solution. Is there a piece that connects the two stems? if yes, just give connections to colleagues among themselves using this particular. otherwise you can create a particular fit with 3 floors and two axes, and then use it for connection.
I hope I've been clear.

No, the two stems do not have a common piece that connects them.
in their operation they move away from each other.
I was thinking of making a mechanism skeleton with a central component to the group that can rotate and 2 others like biella, bound to the central one and the stems.

I think it is enough for a relationship that binds the position of the two stems. Maybe you don't even have to do mechanisms. .

I do not know in detail your application, it is difficult to give you advice on the best method. but one thing I can tell you tries to make a mechanism as simple as possible, because it will certainly be more stable and lasting.
