im currently an engineering student in hopes specializing in automotive suspension.
now this isnt related to real cars, but more.. tiny cars. rc cars. it's been a hobby of mine since i was 7, but im having an issue with one and im completely stumped on why it's doing it
now rc shocks work very very similarly to coilovers.
you have a shock body. a shock shaft. a piston. shock oil. a couple o-rings as seals. caps that go over them to keep everything shut. and a spring that goes over it all.
now, the car im working with has a cantilever style suspension
so the suspension connects to the lower arm.
the camber is adjusted using pillow balls(not sure if there is an automotive term for this)
all this is moved by the suspension.
the issue im having is that the truck doesnt have enough rebound to push itself back up.
im using 80wt(about 1000cst) silicone oil inside the shocks.
all the bal joins are loose and move freely.
im using the stiffest available springs for the shocks.
there is no binding within the shocks either. all the bearings are moving freely and have been oiled
my question is, what could be causing this? ive rebuilt the shocks 3 times with different oils(25wt.. around 300cst in thickness and 45wt which is around 550-600cst in thickness)
next step up would be moving the lightweight differential oil at 3000cst.
when i push it down slowly in the video, it should rebound back up to the set height.. but it doesnt...
it only rebounds back when dropped from at least 1ft
others dont have this issue, so im trying to figure out why it's doing this.. and i cant.
any help is greatly appreciated :thumbsup:
