TA05 parallel mod

Postby aliceisadog » Fri Feb 25, 2011 8:58 pm

I got the idea from gkhunk's evo v modded steering. I had pulled a crawler for parts and had a linkage that was just about right. I chopped a ta05 steering link in half and fitted the bits to the steering knuckles to extend them similar to the vdf setup. Then stood up a short servo to get better throw and thats about it. There is good clearance through the chassis and it works very well with little to no chatter.I will try to get some more pics up soon.

you still have some ackermann happening; your purple link is still shorter than the width between the kingpins.
Only when the link length = width between kingpins will your ackermann become zero.

your knuckle arm extensions, try flipping them so they lean more to the tyre side - then you can lengthen the purple link


be a bit wary of the servo link direct to the knuckle too, geometry suggests you will have imbalance between going L vs R.
The difference in response (exponential type) may or may not bother you, but imho i'd rather avoid it @ design stage.

Akerman is all but 0 and I just adjusted through end point to steer equally left to right. I have some threaded rod so I will try flipping the bits and see how it turns out.

This is basically the same setup I'm working on for my lcg, sept I have less room to play with cause of the centre shaft blocking how high I can mount the link. I'm just using threaded rod I got from a nut and bolt shop and I'll mount the link to the servo off to one side and just adjust the EPA to equal out the steering throw.

Anyone tried this mod on a VDF?

I don't think there is room for the bar. It may have to run above the steering rack.

I have looked at the VDF but yeah not much room. I dont think it is worth doing as the vdf has no akerman any way its just at full lock there is some slopy ness from the angle of the links etc. I have put small 2-3mm peices of fuel tube between ball and rod ends and ti has worked a treat in getting rid of most play.

VDF is already zero ackermann from the factory, and as-is gets more angle than the stock CVDs can handle.

Stock ballcups (black plastic) get sloppy quite quickly, replace them with their Low Friction (dark grey) cousins
which last much longer... most pro chassis i add those during the build & never bother using the blacks.
Use brass or steel ball screws too, the coloured aluminium (hopup) wear out faster.
