3 wheeler, but not as we know it, Jim!

There are various routes to electrical reversing 3 wheelers, and a starter motor drive to the prop. shaft is one, but it will require comprehensive electrical interlocking, to ensure the engine drive is in neutral. A form of "soft start" would be useful, along with a dog clutch arrangement to disengage the electrical drive, when moving forward under its own "steam", now steam, there's a thought!! , I digress. Conventional ring-gear/starter motor pinion sizing would be too bulky for my requirements, so I'm considering 'bike starter motor, driving the 3 piece prop. shaft via a Gillmer,( toothed timing type belt) Belt, with a dog clutch to engage/disengage, wand a solid state 'soft start' control.to make the whole set up manageable. Well that the rough concept,so far! and that's assuming I bother at all!  ..Morrag

Mmm, electrical interlock could be done by neutral switch and clutch, that should cover it. Not sure how you'do a soft start with dc, would probably be similar to forklift (thyristor and comutating capacitor from dim memory). Would it need it anyway? Intermittent  switching would be my choice for starters. Oops, awful pun..
The engagement issue would be solved by use of a pre engaged starter. I'm tempted to try it I must say.
All the best,

Keeps it simple and simple works.

Like rowlocks maybe!!! ...not you Huw, what you wrote made for interesting reading and shall be entered into the equation!!   Morrag

motability scooter motor and switch gear and friction drive rubber wheel

[morrag]

That's another interesting possibility,Mike, so if I can locate the motability scooter info & then "bits" it could be a promising alternative....Mmmmmmmm, cheers for that , Morrag

got one here  hardly used (mother in-laws) but batt n, charger have been nicked  n, its 24v main feed but it will run n, move on 12v so its got the power especially if geared down ,

[morrag]

Mike, I'll send you a PM regarding that, OK, Morrag

I've got a mobility scooter motor thats going in my project, easy to use.

Interesting design Morrag ;-)

Can you post a few pics of what you have in the way of that mobility scooter drive Gaz?  Morrag

Be Monday , will be in the shed again then.

[Gaz]

Sorry Morrag, will be in the shed tomorrow and I'll grab some pictures

Things have been a might slow of late, what with Xmas and all, plus the sort of weather that most deffo. feeds my SAD syndrome, anyway, I have now finished the brakes!! see pics. I'm using Landrover 2 master cylinder and brake flexible hoses, copper brake lines, and brass "T" pieces, ex-Spitfire, from an excellent company in N.I.The rear brake is a modified Honda GL backplate, that now provides a handbrake, and an externally operated hydraulic footbrake, using a BL type "Mini" slave cylinder.  More to come....................Morrag
