The likelihood of damage other than what you have experienced with the wheel, is probably, none.
I hit a cast iron water meter cover (left by a careless worker) at 35 mph which bent the alloy rim severely enough to break the tire seal. Other than the rim having to be repaired, no other damage was found.
You can knock your car out of alignment by running over large objects at speeds over 30 mph, and believe me, you will HEAR the damage being done...
