New VEGA 'Twin Track' diff gears
http://www.oople.com/rc/photos/misc/...atwintrack.jpg Vega Twin Track Differential Gear machined from high quality acetal same as our idler gears. Designed with differential longevity in mind the twin races help to decrease plate wear and increase differential life before a rebuild is required. Twin races also help spread plate load across the ball races decreasing slip. Fits, Tamiya 201, Kyosho RB5 and Team Associated Check out the VEGA product page for this and more items on the Team Xtreme website |
I assume it would not just fit the Vega 201, but also the regular TRF201? :)

What a simple yet great idea :thumbsup:
|
pick mine up later looking forward to ball diffs lasting longer in sc10 :-)
|
what about adding more balls lol sorry but think theres a thing were more balls would need less tension and give more grip better/smoother diff
|
This does indeed look like a good product. I think the further out the balls are (the more leverage) the easier it is on them. If you imagine the balls really close into the centre, the diff would need to be super tight to stop it slipping.
Spreading the wear like this can only be a good thing for sure. |

Thanks Will, that's better.

More balls would equal more tension :woot: and more surface area :o Thats why we have done them this way :thumbsup: |

Any ideas on the price ? :thumbsup: |
£9.16

Yeah it is an interesting idea. It's something that Schumacher tried out on the touring cars a good number of years ago (2003 ish i think). From what I remember, it gave a slightly different diff action, and I seem to remember there being more "wear" on the plate on the inner track. Never did work out why, and we went back to all the balls being on the same PCD.

When the diff is diffing the balls will not rotate at the same speed, inner track balls will turn slower than the outer balls one track will wear more than the other. Giving odd diff wear and inconsistancy in tension/slip
|
The odd wear is due to a minute amount of deflection plus, as Mark said, different pressures on the different ball tracks. I think I had something similar on my RC-Lab and it never worked right then either. The only way to reduce wear, is to mount the balls as far out as possible and support the diff plate up to the point where the balls contact the plate.
In the end, the plate is a wear rate item, it has a finite life, some diff's are better than others. |

Thanks for putting the link up and we've had a look at it. Ours is different as our inner track is further from the centre - which will give a consistent diff action. In back to back testing they have lasted more than twice as long compared to the conventional diff's. :thumbsup: |
Ashley run Vega with new Diff Gear and it was Ace :thumbsup: Made the C Final Shame we had nothing to go with our 6th in round.
|
Anybody else run/tried these twin track diff gears ???
Was thinking of giving them a try........ cheers |
been done before years ago:D

This took the number of balls from 9 in the original diff to 16. I fitted one to mine and it lasted FOR EVER, even using the standard carbon chrome diff and thrust balls (i've still got it:)). Touring cars are a bit more focussed than a basher's car like the XTR21 so I can understand people saying it affected the diff action in that application but I never noticed the difference TBH, the diff just lasted longer. Similarly I don't think you'd notice much difference in diff action in a 2wd buggy when you're trying as hard as you can to drive it on a bumpy, slippery surface. This looks like a good, well thought out upgrade, will be keeping an eye on the Team Extreme site to see how it goes. |
