Electric Wheel
Hydrostatic vs. Hybrid
Air Craft Tugs
Hydrostatic
1)
Seamless
torque
2)
High
Fuel Consumption due to running high pressure pump and plumbing
continuously during operation
3)
I.C.E.
runs continuous
4)
Hydraulic
operation of components through entire unit
5)
Hydraulic
hose lines and pumps leak fluids on the tarmac and maintenance
6)
Automatic
transmission went to electronic valve
7)
Limit
to number of devise to run by size of hydraulic pump and heat
8)
Volume
restricted
9)
Size
limitations
10)
Limited
access and space
11)
Small
minor leaks make for a filthy machine maintenance issue
12)
High
pressure blow out safety issues
13)
Frequency
of routine overhaul per hour
14)
Normal
noise levels high, pumps, valves, I.C.E. all emit noise constantly
under use
15)
Separate
generator required to power electric accessory implements
Hybrid
1)
Seamless
torque
2)
Much
reduced fuel consumption with twin power reserve (fuel and
battery)
3)
I.C.E.
runs only when battery pack is low, intermittent as needed
or quick charge plug in.
4)
Electric
servos driving components
5)
Wiring
with today’s connectors and technology almost plug
and play and maintenance free
6)
Auto
wiring is very complex however resulting in rare problems
7)
Present
technology electro I.C.E. power can use modules serviced
by a single power conductor with digital encoding running
parallel on same conductor
8)
Electric
conductors don’t leak fluids and machine remains clean
9)
Appropriate
size conductors and use specific connections limit safety
issues
10)
Overhaul
per hour most likely cut by at least 50%
11)
Reduced
noise due to hybrid drive power switching while in use
12)
Electric
power supply available as integral part of device
