hydraulic suspension

[egdo]

Bye.
I wanted to ask for an opinion on hydraulic suspensions mounted on work machines such as semovent or tractor mixers.
according to you what is the best position of the cylinder for there front suspension? with stem at the bottom or at the top? and possibly for the back one.
I look forward to some advice on how they are correct according to you.
Thank you.

Hi.
Can you post a pattern of the two solutions? so who reads must not imagine what you mean

something similar to this basically, photos found on the internet

does not answer the question, but they have always told me that with the stem at the bottom, especially for the tire cylinders, the risk of threading increases. also applies to these applications?

I think that having the stem at the top allows better protection from possible pietrisco and dirt that impacting on the chromiuming could damage it, causing then microfiling.
This answers in part to the initial question, for me it is better to have it up.
However, I do not take care of tractors and means of work.

the positioning "right" or "rovex" does not affect the functionality, of course, the choices are due substantially to three reasons:

- encumbrance, especially in the case of anterior axles of tractors, the available space is much less than what is thought

- connection pipes: mounting the stem down allows to simplify the path of the pipes a lot, and in some cases it is a compulsory choice in the case of cylinders with "importing" racing like the self-leveling combiners

- protection of the stem: after the other two conditions are met, if the stem is in protected position, it is better

the speech is different in cases such as the front forks of motion: the reversed fork, which is the one with the stems down, is more rigid than the traditional fork, despite the disadvantages, very often it is used with the stems down to obtain a greater driving precision.

I fully agree, I would add only that the stem could be protected with a bellows or if you decide by position with stem down, you can consider the idea of making drain holes on the cylinder head, for any losses.

It has nothing to do with the demand for egdo, and I apologize if I go ot but the telescopic fork of the motorcycle is born with the stems below, then some builder has begun to overthrow them, especially for the moto da cross, for various reasons, so the "rovesciata" was that with the stems up.
for a long time now they have turned it again, to increase its rigidity and reduce the masses not suspended, and we returned to the disposition of half a century ago...
But reading on the net all call usd, that is, reversed, the fork with the stems below, but for me, that I have witnessed the first and second overthrow, the traditional fork" is that of the morini and the triumphs that made me dream of as a child, the "rovesciata" is that I had on the maico well or on the mach3 500.... but I do not regret it because that " traditional" but very modern of today
I am sorry for the introductory and, in any case, for what may be my opinion, in an application like that of egdo, there are important considerations for the protection of the stem and the seals, and those on the accessibility/functionality of the hydraulic ducts. While the first problem you can solve with a bellows, if the suspension has the sheath below the pipes must inevitably follow the system's excursion. for this reason I would put the sheath up, so in a position called traditional for me and overthrown for the rest of the world...
