JRX-6

A 5-link suspension is superior to single wishbone. And it's ballsy :-)

Geile Scheisse!

[Thomas P]

Love it!! Nice Elvo

[sparrow.2]

Lekker lekker!

Look forward to seeing it in action soon. Now all you need to do is breed it with the pannenkoeken-special you drove in Langenfeld and you'd really have something special

You definitely also need a SACS front end to go with that

What do the front two links do?

Wow, that's really old-school and brings back memories.
Back in the day we found the link set-up worked great on rough tracks, but the wishbone suspension worked better on smoother surfaces.
Not sure how you're going to keep your hubs from rotating/flopping without the extra side link.

Nice job though

Have always loved the sophistication of the JRX2 suspension - that looks awesome.

Please do post your thoughts on how they perform.

Any better pictures on the hub and hingepin mounting? Might want to "steal" your ideas on some future project car! (with your permission of course )

they stop the whole thing from flopping around

[JonMack]

Yeah some more detailed photos would be great, with the wheels off maybe? I love it though, it looks awesome!

Couldn't have put it better. We live in a 3-dimensional world, so you need 3 x 2 = 6 links to hold any object fixed in space. But for a wheel, you may want to replace one solid link by a damper and spring. So that's 5 links left.
Any less and it flops around.


Performance is great. Lots of grip. And it's a reliable kind of grip. Feels very nice especially when the track is made out of differnt materials - like cobblestone patches. First couple of batteries I was on the same pace as with my regular X-6.

So an overall net gain of 0%

Interesting how does it run? Got any video?

I think you will find he means he is the on the same pace as a car that has had multiple runs and much set up work down to it to achieve its pace within just a couple of batteries....... with more runs he would expect it to become better than previous....

Really cool idea, always wanted to see how this would work out on a modern 2wd. The problems I see happening, compared to a full scale "5 link" where there is a fixed lower arm and steerable hub with toe link are:

1.) It is going to be hard to keep everything dialed the way you want it: ie advanced user required, not simple to do.

2.) On this setup, changing toe curves involves changing the length of the lower suspension arm.

3.) Toe is Always active unless you are using a 0 deg rear pivot block or similar method of mounting links on the chassis.

Good luck with this and please keep us updated on your progress!

Right on, DMS and TS.
Given an infinite supply of ball joints and turnbuckles and the ability to (re)design the car around the suspension, I'd keep running the 5-link. In the real world, a standard X-6 is still the car to have.


Version 3 would really need the lower links to be parallel - like with a 0° toe-in block as TS stipulated. And new hubs. And a saddle pack chassis.

forward links also need to be longer to minimise geometry changes during suspension travel

[Chris Doughty]

get some xx4 steering linkages on the front of it

Yep. Battery is in the way. That's what I meant with '(re)design of the car' and 'saddle pack chassis'.

[OldTimer]

Better wheel out the S2 or borrow Elvo Snr's CR2
