Drivetrain Of A Working Machine And Working Machine

Abstract: The present invention relates to a drive train (64) and to a work machine (50), the work machine (50) having at least one first driven axle (56) and one second driven axle (58), and respective wheels (60) of the first driven axle (56) having a smaller effective diameter than respective wheels of the second axle. The drive train (64) has an electric traction motor (66), a transmission (68) and an axle disconnection device (70). A drive shaft of the transmission (68) is connected to an output shaft of the traction motor (66) and a first output shaft of the transmission (68) is connected to a drive shaft of the axle disconnection device (70). An output shaft of the axle disconnection device (70) is designed to be connected to the first axle (56) and a second output shaft of the transmission (68) is designed to be connected to the second axle (58). The output shaft of the traction motor (66), the first output shaft of the transmission (68) and the second output shaft of the transmission (68) extend in one plane.

Specification

1. Drivetrain (64) of a working machine (50), wherein the working machine (50) has at
least a first driven axle (56) and a second driven axle (58), wherein respective wheels (60) of the
first driven axle (56) have a smaller effective diameter than respective wheels of the second axle,
wherein the drivetrain (64) comprises an electric traction motor (66), a transmission (68) and an
axle disengagement device (70), wherein a drive shaft of the transmission (68) is connected to a
driven shaft of the electric traction motor (66), wherein a first driven shaft of the transmission
(68) is connected to a drive shaft of the axle disengagement device (70), wherein a driven shaft
of the axle disengagement device (70) is configured to be connected to the first axle (56),
wherein a second driven shaft of the transmission (68) is configured to be connected to the
second axle (58), wherein the driven shaft of the electric traction motor (66), the first driven shaft
of the transmission (68) and the second driven shaft of the transmission (68) extend in one plane.
2. Drivetrain (64) according to claim 1, wherein the drive shaft of the transmission (68)
also extends in the plane.
3. Drivetrain (64) according to claim 1 or 2, wherein the drive shaft of the axle
disengagement device (70) also extends in the plane.
4. Drivetrain (64) according to one of the preceding claims, wherein the driven shaft of
the axle disengagement device (70) also extends in the plane.
5. Drivetrain (64) according to one of the preceding claims, wherein respective shafts of
the drivetrain (64) extending in the plane are arranged axially parallel to one another.
6. Drivetrain (64) according to one of the preceding claims, wherein the first driven shaft
of the transmission (68) is arranged coaxially to the driven shaft of the electric traction motor
(66) and wherein the second driven shaft of the transmission (68) is arranged offset to the first
driven shaft of the transmission (68).
7. Drivetrain (64) according to one of the preceding claims, wherein the plane extends in
the transverse direction of the vehicle.
16

8. Drivetrain (64) according to one of the preceding claims, wherein the transmission (68)
is configured to provide a neutral position.
9. Drivetrain (64) according to one of the preceding claims, wherein the drivetrain (64)
comprises a control device for the axle disengagement device (70), wherein the control device is
arranged on the transmission (68).
10. Drivetrain (64) according to one of the preceding claims, wherein the drivetrain (64)
comprises a parking brake, which is integrated into the transmission (68)
