Subject: Hydraulic Drive
If anyone out there knows something about hydraulics, please
give me
your opinion on the use of a hydraulic pump (driven by an EV
Warrior) to
drive hydraulic motors that drive the tracks and cylinders
that control
elevate and rotate. I know that hydraulics can pack a
lot of power into
a small space, but I'd like to know the tradeoffs with
regard to weight
and battery consumption.
As I see it, one of the
benefits of a hydraulic track drive would be
that it allows the electric
motor to operate efficiently (driving in one
direction without abrupt
current changes), while providing a variable
amount of power to the
tracks. However, I'm not sure if such a hybrid
approach would
actually save space/weight/energy/maintenance/cost as
compared to an
all-electric solution.
All comments and suggestions
welcome.

PS. Joe
Sommer, do you have an estimate for the minimal amount of torque
needed to
drive our tracks competitively? I know we need about 250 rpms
at the
drive shaft, but I need to know the torque as well to compare
hydraulic
motors.
