2012 Trike Plan
I'm still working on the plan for
the new delta trike. I think I've got it just about like
I want it to be.
It's going to use a 6-7 speed hub
with a second chain going from a gear mounted on the inside spoke
flange to the gear on the right real axle. The pedals will
drive the right rear wheel and the assist motor driving the left
one.
The front wheel and both rear
wheels will have scooter type band brakes. The front and right
rear brakes will be operated with the handlebar grips while the left
rear wheel with be operated with a seperate control so it can be
used as a parking brake.
The latest drawing has the
batteries where they will be placed and the motor drive where it
will be. I have a 500w 24v motor that came off a wheel chair
that I plan to use with it. The motor already has a geared
transmission on it that is designed to run 10" wheels. I'm
going to use a 24t gear on the motor and a 14-16 tooth free wheel
on the axle to speed the output back up a bit and allow for
pedaling without using the motor.. This should give it about 12
mph full speed on the electric motor only.
The batteries will be two 12v 35 amp
sealed scooter batteries. I still haven't drawn in the seat mount
but it will be adjustable.
Here is the latest version of the
drawing.  |
