HSP Metal driveline

Here is a list of parts that I used for a pretty rugged and almost all metal driveline:

3x HSP 02024 Diff Complete
2x HSP 02030 Drive Gear
2x HSP 02016 Universal Loint ( 1 pair )
4x HSP 188015 Wheel axle ( 2 pairs )
2x HSP 06022 87mm drive shafts ( 1 pair )
4x HSP 02038 Ball Head screw

I made some adapters, gears and spacers to get it to fit into the normal diff housings. See pictures.

Wishbones, turnbuckles and steering pins also need adjusted parts (in length) to compensate for the smaller diff & changed axle.

Running this setup successfully with a pretty powerful sensored brushless motor for some time now.

very nice work!!

works nice :wink:
thnx for the advice and files!!!

have you found metal gears (spur & pinion) for the center diff too ?

4

I’ve recently converted the spur and pinion to 32dp/mod0.8. (the files are on thingiverse) Currently my spur is made of polycarbonate, and pinion is metal. (Robinson Racing RRP-1714 or RRP-1716) There are lots of rc cars using 32dp, so finding the right pinion shouldn’t be a problem anymore.

what about printing the spur-gear v0.8 on shapeways in metal ?!
anyone tried this ?!

I wonder how expensive that will get. In polycarbonate my spur lasts at least for 15 packs of quite rough driving. You could buy a spur for a different car and modify it to fit.

pice is the point. i uploaded the Spur_Diff_57_mod08_GearV3.STL to my shapeway account. it would cost about 50€ in stainless steel.
(the “older” model Spur_Gear.STL about 40€, volume is a little smaller)
i only got ABS atm. probably would need to print a new spur gear after ever run :wink:
dont know if my Replicator can handle polycarbonate as well, yet

i put it up on shapeway, hope you dont mind (if so then just tell me and I remove it) https://www.shapeways.com/designer/helmarw

yesterday i printed it in ABS+soluble support, looks quite sturdy.
ill see when my motor and esc arrives, then ill decide if i invest the money
get it printed in steel …

found an other printsevice: http://i.materialise.com/materials/stainless-steel
its a little cheaper than shapeways
