I am building my second 1F2R three wheeler and I want it to be all things to all people. But I live on a very steep hill with a 1/4 mi driveway. In the winter you need a good 4x4. So 3 wheel drive on a 3-wheeler may work. I have come up with 2 plans :
1- hub motor
2- starter motor rubbing on the outside of the tire or geared like on the brake rotor outside
So either way the HP and duration would be very low. Mostly for snow and only when you cant go in 2wd ,like 2 mi max. 5 min? All "I" need is to run it the 1/4 mi up my driveway. So any Ideas on the electric front? 12V? Or like KERS on F-1 race cars
I didn`t love the friction drive in the snow idea, but it was simple. If made tight enough to the tire it might work. If I used a car starter motor I think I would try to use the Bendix of the starter to some how engage the drive,so it would only turn when you need it. Although, with the one way clutch it solves the problem of engagement of the gears at speed. 10 MPH. A good thought.
I was afraid the hub motors wouldn`t work well because of the slow speed heat build-up.
The price of the components are a tad high too. What would it take to make a controller for a 12V starter using a 12V battery? I have lots of used starters around here and winter is coming. My trike weighs 1200lbs with With me in it there is 400lbs on the front wheel (1F2R). It is powered by a 72 hp Subaru 3 cyl with 5 speed transmission driving the rear wheels.
See this pic :
The trike works well. I don`t want to redesign it. I want something that, like snow tires, you put on in the winter take off in the summer. Or more likely something you put on when you need it. It could be 20+ lbs of unsprung weight bouncing along. Oh and under $100 would be nice.
I would think that there won't be much weight on the front wheel, and wouldn't provide much traction anyway.
Can you have a limited slip or locking differential? Depending on how often it snows, it may be better to just use tire chains or aggessive tires.
