Electric Drive System The Liebherr rear suspension system is unique in that it avoids problems
normally associated with nose cone and other linkage designs.
System power ______________________
AC It also allows less side motion of the rear tires during axle oscillation
Manufacturer ________________________
Siemens/Liebherr which provides for a wider and more stable stance of the rear
Alternator ____________________________
AC with directly mounted rectifier suspension struts.
Wheel motors ______________________
AC induction motors. Ratio – 37.1
Dynamic retarding ________________
Continuous extended range and
retard cruise control
The Siemens/Liebherr AC drive system features increased
operating efficienccy and reduced maintenance requirements.
