does anyone know what rear axle would fit under a caddy with minimal fabrication? thinking of doing an electric motor hybrid for around town. figure i'll turn the rear wheels through an axle connected to the diff.
-
Syncro Rear Axel?

Syncro Rear Axel?
Whole lotta brackets and suspension work.
Volvo's probably too wide, ditto for more modern pickups... try one of the small 80s pickups?
-
I think even the little Jap trucks from the 80's are a bit wider.. I seem to remeber my little Ram 50 was still wider than the Caddy.. What about a Chevette, Pinto, or if by chance you could stumble into one, the old RWD Corolla..
-
yea, guess i'll have to go to a big parking lot and start crawling under cars with a tape measure. I've looked under my caddy and it doesn't seem all that complicated to do.

Ford 9" FTW :o
I am just saying there are lots out there and they change gears easily ;D ...but in a serious tone, you can get them cut down camaro guys do it all the time. Jeeps were narrow as well maybe a dana 30 or 44?
-
Oooh yeah.. Old Jeeps would probably be close.. There is a ton of goodies and options for a 9" Ford. The placement of the pinion to the ring gear makes them incredibly durable, but beacuse if this also makes them terribly inneficient.. Kind of heavy too... Chevy Vega is the other one I was trying to think of earlier...

1970's Toyota Celicas and MKI's both are 1600 mm wide, in the specs.

Are you planning on using an inline transmission as well and what electric motor will you use. I think with the extra weight off all this stuff plus the batteries the deisel itself will probably loose the mileage the hybrid part creates even if you can get it perfected and you will have so many arms flying around in the cab shifting between modes you'll look like an octopuss driving but it will be interesting to see what you can come up with. Experimenting is fun and we all learn from it here ;D

first off, thanks to vanagoner for the info on the mk1. that is probably what i'll look for.
as far as transmission goes, ill probably just use a reducer pulley on the forklift motor to a larger on the shaft. that way I can put the motor in the truck bed and run a belt to the shaft. I have an old harley belt and cog to use. probaby get some reduction on the diffs as well. most of the electric cars only use one gear to operate in anyway and shifting is usually not done. I only want the setup to go about 40 mph so I can use it in town. due to the lightweight of the truck, i'm hoping to do it with 4 deep cycle batteries. there are several 48 volt kits for light cars that push them to 40 mph. 4 optima 55 amp hour deepcycle yellowtop's weigh 160lbs plus a 75 lb forkift motor is not much different than hauling a fat girl around . I think I can get 15 or so miles out of it on the average trip into town, and look what i'll save on dinner. ;D.

old toyota cars that were RWD were also 4x100 im pretty sure. i know the corolla was, not so sure about the celica. but a chevette/monza/vega rear end would work beautifully too tho. also 4x100, for sure tho.
-
what about old bimmers? they have roughly the same track and 4x100. try a diesel steam engine hybrid with the exhaust pre heating the steam engines water. or perhaps a sterling generator to the electric motor. fun fun
-
Mid-engine mount that mother, and make it a hot hatcher, that would require relatively little modification, well at least for me it wouldn't. ::)

I've done a lot of research on building electric cars. Pay attention to the batteries - I've seen somewhere big LiION batteries developed for small cars which last long and charge fast and the weight you save with that is really important. I've looked for them again but haven't been able to find them...they'd probably be great though. What's most important is that they deep-cycle very well; deep cycle optima car batteries don't deep cycle as well as solar/ wind batteries made for houses - they're more durable and made to last longer and deep-cycle better than any car batteries - you might want to look at them or else you'll be replacing your batteries very soon. As for the axles I don't know, good luck with all this

thanks for the info but there are hundreds of ev's in the ev album running on the optima's so they must be somewhat durable. the lithium ion's are the *** to be sure, but they may as well be made of unobtanium because they are 10 or 12 K just for the batteries. I won't have more have more than 900 in my whole setup. But if anyone wants to donate litium ion's to the vwjones fund for wayward hybrid builders I can send my address
-
oh I saw smaller LIons somewhere, yes they were very expensive though, maybe $4000 for an okay amount of power if I remember. Good to hear about the Optimas though. I'm sure they're more durable for bouncing around than anything else. Then again I hear about forklift batteries working really well too...

A forklift motor sounds interesting if your battery idea works and you wont need the transmisssion then either if you aren't going to go to fast with it and can get the pulley ratios to work out and not have to haul any fat girls. You might have to find one though to help hold the front end down with all the rest of the stuff going in the back. Try to find one of those junk-yard porkers and maby she can get you some access to free parts too. If there's no room left in the truck by the time you get done you can always get one of those little trailers and tie her down if you need more room in the cab for batteries instead. This whole thing sounds like more fun the more I think about it especialy with her strapped down back there covered with diesel soot from the non-hybrid mode once the batteries quit. Hell she'll already be greasy from the junk-yard job and might not even notice the extra soot anyway ;D.
-
LMAO @ fat chick "tied down on trailer,covered in soot" :D (eyes watering)
I think me just wet myself !
Thanks, I needed that !
Funny s_it !

Rabbit TD....you have put too much thought into this for me to be comfortable ;D

No by all means try it if you have access to most of the parts and won't have to spend a fortune doing it. Even if it doesn't actualy save you any money fuel wise you and the rest of us as well will have learned a lot about things like this and you can enjoy the fact that you created something nobody else would even think about trying themselves and be able to say, "Look what I did". All new ideas start out pretty crude. Les Paul, the inventor of the electric guitar died a couple weeks ago and I read an article that said that his first creation was actualy 6 strings and a pick-up he designed on just a 4 by four and then he kept refining it little by little. You already have the pick-up ;). Please don't think I'm putting your idea down, it just seems like a lot of fun and I get these crazy images in my head about stuff like this. If people could get inside my head they'd have a lot of fun, it's just like Disney World in there sometimes. P.S. I'd like to go for a ride once you get it done just to watch people's expressions, I'll even ride on the trailer with the fat girl and I have my own tiedowns too ;D
-
that Fat Bicht riding on the trailer dusted with diesel soot is somebodies daughter, i just want you guys to have some sympathy and respect.
BWAAAA Haaaa Haaaa HHHHHAAAAAAA
damm that was a good one RTD ;D
i've got a 5x8 trailer and can just visualize that so easy
kodak moments
she'd throw up her arm and wave and we'd see the clean crevices from her fat rolls and the wrinkles in her clothes
Lmfao @ you crazy bastirds

Aren't batteries the main thing preventing e-cars from being really viable? I remember Honda offering to swap failed batteries free of charge when the Insight was released circa 2000. You can bet they haven't extended the same policy to all of their current fleet electric hybrids. Dropping 2-4 Gs on a new battery setup every 5 years just doesn't seem that appealing or environmentally friendly...

you are absolutely correct. that is why an electric car is not a viable option for most. a hybrid on the other had is. look at how successfull the prius is. that is because the batteries are not running all the time and don't have to be replaced often. I figure the batteries in my setup should last 5 years or so since they will only be running less than half the time. and it will only cost about 700ish to replace them. 700 dollars is 200 gallons of diesel. that's a 9000 mile payback. At the relatively low amp draw and speed that i'll be using, I should get nearly three times that out of the batteries. and even if I only get twice that, how much is 18,000 miles less wear and tear on my turbo diesel worth? And electrical engines are notorious for running for years with almost no maintenence. not to mention the coolness factor of pulling into work completely silently on battery power and recharging at work. Plus, that is 200 gallons of diesel at todays prices, I could easily see that dropping to only being able to buy 100 gallons for 700 dollare, or even 50 :o

lol absolutely no offense taken at your comments. I got a chuckle out of them too. i'm an easy going guy and it is nearly impossible to rile or rattle me, that is why i'm able to drive a VW diesel :P thanks for the encouragement. I think i'm going to go through with it since it really won't cost me more than 1200. I've been whatching EV equipment on Ebay and i'm sure I will have NO trouble unloading the electronics if I don't like the way it performs. Geez, that stuff is snapped up like gold. I'm just stuck now waiting around for a rear axle from an escort or vega that is practically free, since that is the only way in which I buy things. I found a sprague clutch last week that will keep the electric motor from running until the motor is actually turning faster than the shaft. I got it off a junked pto shaft. That should keep the electric motor freewheeling the sprague cutch until I power it up. Now i'm thinking about putting an alternator on the drive shaft too with a 12 volt field that is powered by a microswitch only when I put on the brake. that way the alternator would freewheel when i'm driving with diesel and not cause any drag on my system, but would engage when the brake is pushed and the alternator would act as a brake and give me regen on my batteries at the same time. god knows my caddy brakes need a hand stopping the GTD turbo diesel. all for about a 10 lb increase in weight and and alternator which I already have. think that would work?
