semirigid rear suspension 1

[aassaa]

Hello

The torsional beam of a semirigid rear suspension sometimes is a tubular profile with a central "U" or "V" shape that guarantee the roll rate stiffness of the suspension, but...what i do not know is why some of this "U" transversal lenght ("X" direction on vehicle coordinate system)of the tubular component it is delimited with a clinching method, that is, the tube has stamped two ribs that fix the tubular shapes that are on contact.

I know that this ribs are patented from an european company, but why is this method so important ?

Can anyone recomend me any site to get more information?


Thanks

Find the patent. Read the teachings. Apply salt.

Then, read the claims. That's where the really important stuff is buried.

Are you talking about the Bentler twist beam suspension? If so why are you being mysterious?

Ok thank you MikeHalloran, it has been helpful, i found interesting things.

Greg: i didn´t want to be mysterious, only want to know the function of such clipping.
By the way, do you know it?

I'll hazard a guess. My Dad's '58 Chevy had the usual American soft springs, but once you got it rolled over onto the bump stops, it would corner decently.

Simply increasing the roll stiffness would make a car ride hard, but a graduated, or stepped, roll stiffness could allow a smooth ride and acceptable cornering too.

Well, I didn't really understand this bit "delimited with a clinching method, that is, the tube has stamped two ribs that fix the tubular shapes that are on contact."

...and if it is the Bentler twist-beam suspension then I can look at the drawing or a car to get an idea.
