Axle
ekremors1 - 29/9/06 at 05:31 AM

Dear all,
I am building my own car from the Renault Clio 1.4 engine. I put the engine at the back part of the car.
My problem is ; because of the design there had been an angle occurs between axle joint points.

Is it work well?

Thank you Rescued attachment AXLE.JPG

If you are using UJ's then it won't work
If you are using CV's then it might work.

As i'm looking at the sketch i think that the angles are to big.

Joints are original. I did not make any modifications.I dont know thay are UJ's or CV's.

Also angles are not to much as I draw at the picture.

IF standard then they will be cv joints

they will take abit of an angle but not as per drawing !

can you take a picture so we can see the angles,
as i might not be as bad as you think !

also the more angle you have the shorter it becomes ( if you know what i mean )

here is the picture of it. Suggestions Rescued attachment DSC00040-rev1.JPG

firstly move the engine forwards a bit to get the driveshaft angles better, then look at your rear shocker angles, because at the moment they are NOT good!

Is it also possible to move the wheels back a touch if the engine cannot move forward.

As Nat says current rear shocker angles are interesting, i would guess this would have the effect of moving the wheels forward and up in bump, would make for a very lively back end.

Are you using a torsion bar set up at the rear? Can you post some overhead pics of the back end and closer pic of rear suspension so we can see angles and set up better. Looks like the rear suspension pivots from the very rear corners of the car so i can see where you are coming from with the shocker angles. On reflection it may be OK. Certainly comparing it to standard 7 type rear shocker angles then they are different. Where did you get the inspiration, from the donor?

It does look like an interesting vehicle. What will it look like finished? Do you have any sketches / renderings?

another thought, you appear to be feeding all your rear suspension loads into an area of the chassis with little or no strength!!! (unless of course the bar at the rear is the anti roll bar, in which case ignore this!)

Sorry to be critical but I am quite experienced with building transverse mid-rear engined vehicles and that is not going to work!

The way to gain strength and have rear suspension that works but it still easy to do is use trailing arms at the rear, mounted off the last transverse chassis member forward of the engine.

Look at an autograss car or something like a GTM for inspiration.

This system is not torsion. There is an ball bearing on it with hand made adjustable coil over.

I and my friends jump on the chassis's different point and see that suspensions are working very well.

Also I can move tyres back a little bit more. But this is not the answer.

For example when you change the suspension and spring of a normal car with race suspension and spring there is an ange occurs at the drive shaft.

Is this angle damage drive shaft of affect drive comfort??

Also I did not finished the chasis. There are alot of part to be weld at suspension and chassis. It is going to be more strong.

Sory DarrenW I forget to answer your questions..

I have no last pictures of the suspensions. When ı take it ı can send it.

I have no sketches. But trying to shape it like similar 7.

The most different parts are the back engine and every part is hand made that is all.

If my eyes don't decieve me that is a single leading arm suspension design. Interesting choice, a trailing arm would at least have had the advantage of being able to mount onto a strong part of the chassis.

Besides the strength of the chassis (or lack of) at the point where the arms are mounted, the actual trailing arms themselves look very narrow. Are they capable of taking the lateral forces you get during hard cornering without deflecting?

Marlin run one of the driveshafts on their 5EXI at plainly ridiculous angles. I don't know if this has caused any problems, but seeing as it's runing the Rover T16 Turbo engine I can't belive that CV will last long. It really put me off buying one (my wife loves this car and wanted me to get one).

The uprights are held in the back in the pictures of ekremors1
That explanes why the coilovers are in this angle.

I presume if you're driving this you will get lift at the rear.

Those angles at the marlin scares me.
2 or 3 cm off-line at rest would be my goal.
