Abstract

Claims (42)

1. A ground support tractor having cab forward and cab aft configurations, the ground support tractor comprising:

a common chassis having a forward mounting location and an aft mounting location;

a drivetrain coupled to the common chassis; and

a battery system coupled to the common chassis;

wherein, in the cab forward configuration, the battery system is coupled to the aft mounting location and positioned above the drivetrain; and

wherein, in the cab aft configuration, the battery system is coupled to the forward mounting location and positioned forward of the drivetrain.

2. The ground support tractor as recited in claim 1 wherein, the drivetrain further comprises an electric motor and a transaxle coupled to the electric motor.

3. The ground support tractor as recited in claim 2 further comprises first and second drive wheels operably coupled to the transaxle.

4. The ground support tractor as recited in claim 3 wherein, in the cab forward configuration, the battery system is positioned above the first and second drive wheels; and

wherein, in the cab aft configuration, the battery system is positioned forward of the first and second drive wheels.

5. The ground support tractor as recited in claim 3 wherein, the common chassis further comprises a frame with first and second forward wheel wells coupled thereto and with first and second aft wheel wells coupled thereto; and

wherein, the first and second drive wheels are respectively positioned within the first and second aft wheel wells.

6. The ground support tractor as recited in claim 5 wherein, the forward mounting location is positioned above the first and second forward wheel wells; and

wherein, the aft mounting location is positioned above the first and second aft wheel wells.

7. The ground support tractor as recited in claim 5 wherein, in the cab forward configuration, the battery system is positioned above the first and second aft wheel wells; and

wherein, in the cab aft configuration, the battery system is positioned above the first and second forward wheel wells.

8. The ground support tractor as recited in claim 5 further comprises first and second steering control wheels respectively positioned within the first and second forward wheel wells.

9. The ground support tractor as recited in claim 8 wherein, in the cab forward configuration, the battery system is positioned aft of the first and second steering control wheels; and

wherein, in the cab aft configuration, the battery system is positioned above the first and second steering control wheels.

10. The ground support tractor as recited in claim 8 wherein, in the cab forward configuration, the battery system is positioned above the first and second drive wheels; and

wherein, in the cab aft configuration, the battery system is positioned above the first and second steering control wheels.

11. The ground support tractor as recited in claim 5 further comprising a motor mount coupled to the frame between the forward wheel wells and the aft wheel wells;

wherein, the electric motor is coupled to the motor mount.

12. The ground support tractor as recited in claim 5 further comprising a rear suspension coupled to the frame;

wherein, the transaxle is coupled to the rear suspension.

13. The ground support tractor as recited in claim 5 wherein, the transaxle is positioned between the first and second aft wheel wells.

14. The ground support tractor as recited in claim 1 wherein, the drivetrain is a common drivetrain.

15. The ground support tractor as recited in claim 1 wherein, the battery system is a common battery system.

16. The ground support tractor as recited in claim 1 wherein, the battery system includes at least first and second battery packs.

17. The ground support tractor as recited in claim 1 further comprising a battery rack coupled to the common chassis;

wherein, the battery system is coupled to the battery rack.

18. A ground support tractor having cab forward and cab aft configurations, the ground support tractor comprising:

a common chassis including a frame with first and second forward wheel wells coupled thereto and with first and second aft wheel wells coupled thereto, the common chassis having a forward mounting location positioned above the first and second forward wheel wells and an aft mounting location positioned above the first and second aft wheel wells;

a drivetrain coupled to the common chassis; and

a battery system coupled to the common chassis;

wherein, in the cab forward configuration, the battery system is coupled to the aft mounting location and positioned above the drivetrain; and

wherein, in the cab aft configuration, the battery system is coupled to the forward mounting location and positioned forward of the drivetrain.

19. The ground support tractor as recited in claim 18 further comprising:

first and second steering control wheels respectively positioned within the first and second forward wheel wells; and

first and second drive wheels respectively positioned within the first and second aft wheel wells.

20. The ground support tractor as recited in claim 19 wherein, in the cab forward configuration, the battery system is positioned above the first and second drive wheels and aft of the first and second steering control wheels; and

wherein, in the cab aft configuration, the battery system is positioned forward of the first and second drive wheels and above the first and second steering control wheels.
