LDO Posted October 15, 2013 Share Posted October 15, 2013 Specifically, trikes with chain drive and a simple solid bar for a rear axle. Is there such a thing as a chain drive IRS that allows the inside and outside wheels to rotate at different speeds in turns? Just curious.

LokisTyro Posted October 15, 2013 Share Posted October 15, 2013 Do you mean pedal trikes? 'Cause I'd like to see a pedal trike with an IRS with an open differential if there was one. Quote Link to comment Share on other sites More sharing options...
wisdonm Posted October 15, 2013 Share Posted October 15, 2013 (edited) I would say that it varies with wheel tread, speed, and traction. Wider wheel tread, slower speeds, and more traction (wide tires) will produce more hop. A go cart at speed has little hop, but will be almost impossible to push with the front wheels turned. A go cart with thin bike like tires would be much easier to push through a turn. As for a chain driven IRS, I would check out ATVs. http://www.alibaba.com/product-gs/509885314/1100cc_chain_drive_limited_slip_differential.html Edited October 15, 2013 by wisdonm Quote Link to comment Share on other sites More sharing options...
Blown03SVT Posted October 15, 2013 Share Posted October 15, 2013 I imagine there would be some sort of rudimentary differential in the center of the sproket much like a 10th scale r/c on road pan car... Quote Link to comment Share on other sites More sharing options...

It's all for a model idea that has been in my head for a while. I've seen photos of small sand rails with motorcycle engines and chain-driven I.R.S., but no diff (it's in sand. No wheel hop there). Thanks. Quote Link to comment Share on other sites More sharing options...
Craig Irwin Posted October 15, 2013 Share Posted October 15, 2013 All of them that I know of have a differential. Having said that I will tell you that they can steer hard because you can't lean like a two wheeler. Quote Link to comment Share on other sites More sharing options...
