There has to be some additional trick otherwise you would have to wave goodbye to motor break
Yup thatās what I was suggesting too
Im also curious about this, i couldnt see the trick used here. Maybe there is a patent filed?
Ahh no trick here sadly. Probably really just one-way bearings
I found the video on their youtube channel and the very same question was asked there.
braking an hub board with hubs is less than optimal, let alone a belt boardā¦ ^^"
I mean that solve the differential problame with the 2wd 1motor thing, but then you have actualy 3 motors
At this point you can have one directional bearing and one normal bearing, so you still get all the braking power of the 1wd belt system
Sucks
Turn the one way bearing so itās two wheels of braking and one wheel of power
So when braking for example with a one way bearing, it means the inner race of the bearing is rubbing on the motor shaft? Right? I wonder if thatāll be a problem long term. Iām down to give the one way bearing a try.
I think it is the opposite : the bearing is on the motor pulley and is fixed somehow on the shaft : when the motor accelerate the bearing doesnāt turn so the pulley is fixed on the axle and turns,
when the motor brakes, the bearing act like a bearing and so the pulley just roll free with the belt and wheel
at least thatās how Iād do it
I think you would need to adhere them somehow so this didnāt happen, but I could be wrong
Why would a one way bearing affect braking? The rotationnis still the same direction, its slowing down? If the pulley doesnt hold, its just one wheel braking? Which sucks but isnt no brakes, right? What am i missing?
A braking force is the same as a reverse force. So even if the wheel and motor are still spinning in the same direction, the motor is pulling backwards and the bearing releases, itās about force direction and relative speed not total speed.
Limited slip / torque vectoring / Torsen esk8 differential would be AMAZING
Unfortunately Iāve come to accept the reality that the single shaft to two motors is not an ideal set up (for me at least)
Iām not sure how to better explain the ride feeling but if you have ever done a power slide on a board before be it a manual or electric, itās like that, but it happens at every speed. So even if you are snail speed and you do a turn, the back will do a really weird power slide and want to destabilize you. For what iām planning to use this board for, which is for small commute distances and to navigate city pavements that tend to have tight corners, this aināt it.
So iām planning to stop this build as is, and remain it in itās single drive.
However! I do not plan to give up on the differential project just yet. I may dedicate another build for it in the future, but i do not want to mess with this board anymore as itās fine as is for now.
