So, older BMWs use a special hydraulic piston with a spring inside to automatically tension the serpentine belt just enough at all times.
by comparison, drive belts on our boards seem to need pretty constant adjustment and maintenance and a belt slip can throw you off your board or prevent you from stopping
So what’s the feasibility of finding a very small version of this guy, and essentially putting it between the motor and the trucks along the axis of the motor mount so its constantly keeping them at the perfect tension?
got a visual example of what that might look like?
seems like it’d be set up similar to the clutch wheel in this image, but how would you have that idler maintain tension, just a spring?
hmmmm seems un necessary. as long as the belt stays tight enough, moving part is not required. those system mainly used for tracked vehicles such as tank.
