Abstract
Systems are provided for a driveline. In one example, a system includes a first electric motor coupled to a first two-stage gear assembly, a second electric motor coupled to a second two-stage gear assembly and separated from the first electric motor, wherein the first and second two-stage gear assemblies comprise a first stage helical gear assembly and a second stage helical planetary reduction assembly.
Claims20
A system, comprising:
- a first electric motor coupled to a first two-stage gear assembly, a second electric motor coupled to a second two-stage gear assembly and separated from the first electric motor, wherein the first and second two-stage gear assemblies comprise a first stage helical gear assembly and a second stage helical planetary reduction gear assembly.
An off-highway vehicle, comprising:
- a battery pack comprising a plurality of batteries;
- a motor unit electrically coupled to the battery pack;
- a first electric motor coupled to the motor unit via a first motor coupling;
- a second electric motor coupled to the motor unit via a second motor coupling, wherein the second electric motor and the first electric motor are separate from one another;
- a first two-stage gear assembly configured to receive power from an output gear of only the first electric motor;
- and
- a second two-stage gear assembly configured to receive power from an output gear of only the second electric motor.
