Finally
arrived is the laser cut stainless steel plate that the
four
electric motors will mount to, the hole in the centre
is where the differential drive sprocket will be protruding.
|
|
The solution
I settled on for the differential drive was to utilise
a 38T 3/8 pitch taper lock sprocket, holes were carefully
drilled
in to the sprocket to match the holes of the diff
and bolted , then a 30mm shaft with an 8mm key
will lock them together. A bonus spin off of the sprocket
is that I now also have a 38T pulse take off to
monitor the diff rpm.

|
|
|
Not quite ready for the duplex sprocket
yet, but you get the idea of how its going to work. |
|
The pillar block bearing is only
mounted for support bracket alignment purposes, once
the motor plate is secured, the bearing will be removed,
allowing the duplex sprocket to fit fairly flush to the
plate and thus reducing leverage on the shaft.
|
|
|
|
Coming together nicely, the electric
motor frame will attach to the sub frames original engine
securing points.
|
|
Bolted down, time to remove the
pillar block bearing. |
|
|
|
Differential torque bar fabricated
and fixed in to place.
|
|
And now with the bearing removed
the shaft stays in exactly the same place.
|
|
|
|
Start of one of the idler/ chain
tensioner assembly's, the plan is to make a top hat style
eccentric insert for
the bearing, two will be required.
|
|
Horayyy !! The motors have arrived.
The power plant for the car consists of four Lynch D135
permanent magnet DC electric motors, quite pricey but
the best PM Motors you can buy, the specifications
of these motors can be found here.
|
|
|
|
Front facing view of the motors
secured in to place, 6mm spacers have yet to be laser
cut for the motors on the right hand side to allow the
chain
and sprockets to be as close to the mounting plate as
possible.
|
|
Side profile, I am using taper lock
17 tooth sprockets on the motors and a single 16 tooth
duplex
sprocket
on the diff drive shaft. |
|
|
|
Pictured at the bottom of the image
is the start of one of the idler sprockets. I've waited
a long time to get this far, hopefully progress will
now speed up.
|
|
Eccentric inserts have now been
made and are ready to be fitted to the motor mounting
plate.
|
|
|
|
Idler Sprocket/ Chain Tensioners
fitted and chain lengths finalised and joined. |
|
The mounting spacers for the
two right hand side motors, laser cut and ready to be
attached. |
