Abstract
A commercial electric drive unit includes an electric motor module and a planetary gearbox module. The electric motor module and the planetary gearbox module are disposed longitudinally in line with each other. The electric motor module and the planetary gearbox module are configured to share one or more lubrication and cooling fluids and a single pump may provide such fluid to both modules. Torque generated by the electric motor is output to the planetary gearbox for multiplication. The planetary gearbox is configured to couple to a prop shaft for output of torque that has been multiplied by the planetary gearbox.
Claims20
A commercial electric drive unit comprising:
- a drive unit housing, comprising:
- a first housing portion, comprising a divider wall and containing a first cavity;
- and
- a second housing portion, mechanically connected to the first housing portion, disposed longitudinally in line with the first housing portion, and at least partially containing a second cavity, wherein the divider wall separates the first cavity and the second cavity;
- an electric motor, disposed within the first cavity and comprising:
- a stator;
- and
- a rotor;
- a motor output shaft, coupled to the rotor;
- a planetary gearset, disposed longitudinally in line of the electric motor within the drive unit housing, the planetary gearset comprising:
- a sun gear, connected to the motor output shaft;
- a plurality of planet gears disposed around the sun gear;
- and
- a ring gear disposed around the plurality of planet gears;
- and
- a gearset output shaft, coupled to the planetary gearset, wherein the commercial electric drive unit is configured to:
- generate electric motor torque with the electric motor;
- transmit electric motor torque with the motor output shaft to the sun gear of the planetary gearset;
- multiply the electric motor torque from the motor output shaft with the planetary gearset;
- provide the multiplied electric motor torque to the gearset output shaft;
- and
- output the multiplied electric motor torque with the gearset output shaft.
