Apologies for the comedy wobbly camera skills, i was really converned not to
drop my camera through the floor onto the road. Also i was concerned not to
injure myself as i was bouncing along trying to fit my hand safely thru that
sharp edged hole.
Here is a video from quite some months ago, it was a short
driving test to check there were no problems with the installation of the
differential and the custom driveshafts to the rear wheels. There was yet no
electric motor drive installed, you can see simply the input drive flange of the
Mitsubishi Shogun differential. My main concern was to check that everything was
spinning smoothing and without any unexpected noises. Also of concern was to
check the re-installed ABS wheel speed sensors were working correctly, this was
a big relief that i could retain the original sensors and keep the standard
vehicle brake system ECU functions happy.
Design of driveshaft between clutch and axle.
Designing the final connecting driveshaft after the clutch until the flange of the rear axle differential. It may or not be as simple as this sleeved coupler shown in this CAD model. This shaft located between a pair of CV-joints will be rotating all of the time being driven from the road wheels at approx x4.2 speed via the diff ratio. So it is important that it will be working without vibration. Given the design constraints of packaging the motor-gearbox and clutch under the chassis, providing sufficient ground clearance while avoiding too much butchery cutting through the vehicle floor or cross beams, i have tried my best to keep an acceptable drive shaft alignment. Noting that all the components are fixed to the vehicle floor/chassis, so suspended independent from direct or any relative motion with the road axle.
Brilliant! 😁
ReplyDeleteGood stuff.
ReplyDeleteI came across your post as I was actually searching for something like this. I think the concept makes a lot of sense, especially if the van is already offering in an AWD option, so an AWD rear axle can be used? Such as the Sprinter or VW 4Motion (Caravelle, Transport, Crafter etc).
Anyway, I am looking forward to following this. /Peter
