EV2Go's - Lithium Powered Trike

The motor sits too low for the pivot to go under it. The bottom of the motor roughly 5" off the ground, by the time I slide a thin sheild underneath were looking at 4.5", and I need a minimum of 4" (100mm) for ADR rules. I am also fighting weight so I need to keep the torque tube and associated par...

EV2Go's - Lithium Powered Trike

EDIT: Not keen to make the motor a stressed member as that is counter productive to what I am trying to do, which is reduce vibration through the motor. As you have drawn it at the moment - if the diff moved up 2 inches then the motor moves up 2 inches (motor solid mounted to the diff and the diff ...

EV2Go's - Lithium Powered Trike

to clarify - the controller is mounted to the suspended frame above or beside the motor - not on the moving motor part.

EV2Go's - Lithium Powered Trike

Woody's catching on but its more subtle than that but the outcome is the same - trying to twist the diff clockwise on one side and anti clockwise on the other side. With rubber bushes the amount is small and the bushes soack it up. But with rose joints it will lock up and not move (nothing to absorb...

EV2Go's - Lithium Powered Trike

I think you are missing the point I am trying to make. try this picure - an exageration of what I am saying http://lh3.ggpht.com/_UxGAw06t3tA/TTgZ1JMW4MI/AAAAAAAAANA/BTK7VV2r4XY/diffexample.jpg unless your diff is made of rubber you can't have one side up and one side down in relation to the frame i...

EV2Go's - Lithium Powered Trike

Yep looking at you photo I think the ford was the same - arms pointing outwards - one pinched the idea from the other by the looks. I had a friend years ago who had a speedway car (cortina) and he slotted the top arms and welded on a panier rod as he said it did the job a lot better. Too much moveme...

EV2Go's - Lithium Powered Trike

What I am trying to say is that by using the rose joints and the triangular arrangement of the top arms - the trike may not tilt but be forced into an up down motion only.

EV2Go's - Lithium Powered Trike

I agree with what you say about torque - the only way to go is a solid connection to the diff. An old ford cortina (I think - that has a 6 cylinder engine) used 2 strait lower arms and 2 diagonal top arms like in your diagram but it had rubber bushes. Trying to run the movement through my head but a...

EV2Go's - Lithium Powered Trike

http://forums.aeva.asn.au/uploads/350/MockFinal-07.jpg Is the motor solid mounted to the diff or via a flexable coupling ? Also is it going to still be a tilting trike ? If so I see some problems with the top linkage length and positioning. Every time you go over a bump the front of the diff will w...

Woody's 1963 Ford Cortina

Thats an iteresting trailer but would you realy want to drive by wire ? If the throttle stuck on it would be a wild (and short ride). You may end up going backwards (in the car) while the trailer is pointing forwards (i.e. jacknife) just prior to a sudden stop. Does this guy have a death wish ?

Simons 1999 Toyota Prius

If there was no oil in it then who knows how much damage has been done up to now. Does it have rubber boots on the ends of the trans axle where it connects to the drive shafts ? If so one may have a crack in it.

Lifepo4 is safe as grandmas scones. Lithium Ion as safe as a politician's promise. OK I'm not a chemist but going by the above (about formats) I was trying to say that LiFePo4 (which I assume is the Lithium Ion format) is the safe one eg Thunder Sky and Sky Energy. But I am told it can still suffer...

an un registered 121 is worth around $200 IMO. particularly look for engine rebuilders. They commonly get old cars needing an engine rebuild which the owners then abandon. Talking with people who have done conversions the sentiment seems to be that its easier to get a registered car approved by Vic...

On a completley different angle about converting a car consider this. Cars before 1995 have less ADR's to comply with - no air bags, crumple zones etc. Engineers don't like mods done in crumple zones or where there is an air bag fitted. Unless you crash test your car ! I believe there is one (only o...

I'm only new to EVs and conversions but what I have learned is that there is more than one type of lithium battery. Lithium Polimer batteries are ideal for model toys like heicopters,plains and cars because they are light and have about 13% more power for there weight than Lithium Iron Phosphate (Li...

TIG aluminium welding

Does anyone know of someone who can TIG weld aluminium for me on a weekend here in Melbourne (I am in Dandenong but will travel) ?
They need to be skilled as the job is tricky - 2mm flat plate and I don't want it to warp.
