Yes, was trying some measurements/template for Hi-Steer using the components of a spare knuckle/caliper.

Should get done this week.

BTW, also need to fabricate this for my Gypsy this weekend:

And a very crude representation of how this would look:

traction bar? interesting...are you getting it done at Suraksha? Guess this would be only for the rear axle, right?

Yeah, this is only for the rear and am getting the fabrication done through Suraksha. I had visited the FAB shop today and gave all the inputs. Should be done in the next few days.

Can somebody explain to me in simple english what are you intending to do. From what I could see your gypsy needs one more capability, climbing walls, everything else is already done

Is that to cut out horizontal movement of the axle?

They say that a picture is better than 1000 words and a video even more better. So, won't bore you with mundane details but this is what it will accomplish (will avoid):



Till now, I have been very gentle on the throttle and have not faced ANY terrain which has asked me to push it in 4WD. However if I have to push it then axle wrap is a serious possibility -- a question of 'when' & not 'if'

Those interested in the details can read a nice article here:

Wana do this -- and in this axle wrap is a certain possibility if traction bar is not there:

WOW -- Khan Sir,

This work deserves a seperate thread "The Axle Wrap (Avoidance) Project".

Is the possibility of Axle Wrap HIGH in SPOA than SPUA???
(EDIT)
Answer - 4X4wire site says "Yes"

What is the downside to installing traction bar? Definitely it limits some movement.

he he, That would be fun -- pure unadulterated adrenalin rush for me.

But on an equally serious note, where ever you have to push hard (assume trying to climb a rock and front wheel not moving easily and you need to throttle up) then you will have higher chances of axle wrap.

I have to get this done because of SPoA + composite springs. These springs are GREAT but by their nature they flex easily (doesn't mean that are spongy -- can't explain it any better) hence chances of axle wrap are more.

This is part of the whole SPoA project, hence have posted it here. It can be spun off into a separate thread later if required.

This is a trade off you "have to" make while going SPoA -- it would/could limit 'some' articulation.

BUT one of the ends of the traction bar has a threaded bolt that takes care of movement not getting restricted during the articulation process. What can also be done is to have Jhonny Joints (Rose/Thiem Joints) so that there is enough of flex at the joints. However I will be getting only regular bushing done + threaded bolt at one end.

Here is an illustration that one of the zukiworld members shared with me on the design concept to be kept in mind

Here are some of the points to consider in a 'triangulated traction bar':

- The length of the traction bar should be of similar length as that of the rear propeller shaft
- The lower bar should be at same angle/parallel to the rear propeller shaft
- The upper bar should be 'as' parallel to the ground as possible


Cheers,

The traction bar is complete and ready to be fitted. Here is a sneak preview of how it looks

The hi-steer has also been fabricated and will get installed.

Got the Traction bar installed last weekend. Only if you have been driving the same vehicle for some time and then you drive after traction bar fitment can you realize the subtle difference.

You don't notice it while driving but just notice the difference in a subtle manner when you start moving or are accelerating after changing gears. At that particular moment, the driveline/transmission feels more taut & free from slop.

Here are the pictures.

Khan,

Do you any photos to show where is the traction bar attached to the frame?

I am trying to understand photo no.3.

Hi Shanawaz,

Fantastic, you have just improved the Gypsy's reliability by leaps and bounds.

How is the articulation? Some Spidey pics please

Regards,

Arka
