Re: New "TSDZ2 Torque Sensor Central Motor"

romelec was so nice to make the CAD of the axle. Some questions still remain. Is there someone with a broken one and can make some more pictures? Ideally together with the attached torque sensor?
Or maybe even send the broken one to me? I'd pay for p&p, so we can maybe make a stronger axle on day.

Does the axle need to be heat treated? Another thing that you might want to consider is make the crank connection to accommodate the spline style cranks.
I wouldn't heat treat it. Also depends on the steel used. But some CroMo steel should be capable enough. Better let it bend than break...

Re: New "TSDZ2 Torque Sensor Central Motor"

I've created the pedal axle in Fusion 360, you can view/download it here: https://a360.co/3gwHR9I The dimensions should be pretty good but an error is always possible. Thanks for modelling the axle. So I can have look at it without having it in hands :) :thumb: Overall it should be fairly easy to m...

Re: New "TSDZ2 Torque Sensor Central Motor"

https://github.com/OpenSource-EBike-firmware/TSDZ2_wiki/raw/master/TSDZ2_different_versions_axles_comparition.jpg There are 2 different shafts and the taper appears to end sooner on the narrow version. Some cranks may seat up against the end of the taper instead of seating on the flat. There are "b...

Re: New "TSDZ2 Torque Sensor Central Motor"

Shame. Didn't look at the screw it self. Not that I could have read it without magnifying glasses anyway. ;) Thanks! I'm not using the supplied cranks, as I had to shorten mine because of the 20" rims I use in my former 26" bike. Could be that the Tongsheng taper is not exactly the same as the origi...

Re: New "TSDZ2 Torque Sensor Central Motor"

That's why I asked for the correct torque the first time, but haven't received an answer yet. I can't find a number. Of course a proper built axle can be used with proper screws as well without risking stripping the gears. It may be that my internal threads are already somehow damaged, which leads t...

Re: what's that sound?

In addition, remember to grease the Spindle and crank. This allows them to slide easily to increase the pressure on the taper while reducing the load on the bolt and the threads. Thanks. I didn't grease them. Good point. I think I remember someone mentioned to heat the crank up with a propane flame...

Re: what's that sound?

Better bolts should be readily available at any decent harware or bike shop. They come in different strength ratings. 10.9 is a good metric rating. 8.8 is common, and unmarked bolts are crap. If the internal threads are damaged, a bike shop or auto mechanic should be able to drill out the damaged t...

Re: New "TSDZ2 Torque Sensor Central Motor"

The hardest thing to duplicate would be the splines, but they are short, few in number and stand proud of the shaft itself so should be less difficult than they might be. IMO, just controlling the seat diameters so the result is closer to a press fit would suffice for many people. I now checked the...

Re: New "TSDZ2 Torque Sensor Central Motor"

As posted above, you can buy the axle alone from eco-bike. Only makes sense when you're based in the US. P&p double the price for shipping to Europe. And you still get the same junk as was installed originally. Same issues. I once had an axle of a MAC hub motor break (it has this large axle bore for...

Re: what's that sound?

Everything in the motor looks fine. All gears look intact, bearings are ok - Chinese style, and I can't find any obvious problem. As I mentioned: When I pedal there is no noise, so it clearly comes from the motor. And it's not a really complicated setup. Motor, 2 gears, another two gears, and that'...

Unfortunately sometimes yes. And NO, it's not good, but there are solutions to help minimize the wobble.
But this thread is for the FIRMWARE only. There is another thread about HARDWARE.

Having the motor support only above 6km/h is just plain stupid. Where are you from? i hear this the first time. maybe you are confusing something with the 6km/h limit for motor support without pedaling? With pedaling, the limit is 25km/h in europe which is good enougt for most situations. Sorry. My...

Well, one, two, or even three po...

Would you consider adding a configuration option to hide the clock altogether seeing how unreliable it can be and how much it can drift if you don’t use the bike every day? I’d personally much rather not see the clock at all than seeing it display the wrong time every time. +1. Makes sense. If it c...
