Abstract
An electrified drivetrain may include a motor, a speed reduction gearbox driven by the motor, and a parking brake coupled to a low-speed portion of the speed reduction gearbox through a shaft that is parallel to a rotor of the motor.
Claims20
An electrified drivetrain, comprising:
- a motor;
- a speed reduction gearbox driven by the motor;
- and
- a parking brake coupled to a low-speed portion of the speed reduction gearbox through a shaft that is parallel to a rotor of the motor;
- wherein the shaft extends along a lateral side of the motor;
- wherein the parking brake includes a disk that partially extends across a longitudinal side of the motor;
- and
- wherein the speed reduction gearbox is positioned on a second longitudinal side of the motor.
5 more elements
An electrified drivetrain of a vehicle, comprising:
- a motor rotating about a motor axis, the motor axis parallel with a longitudinal axis of the vehicle;
- a longitudinally positioned driveshaft engaging an input of a differential;
- a parking brake laterally offset on an opposite side of the longitudinally positioned driveshaft from the motor;
- and
- a speed reduction gearbox, the speed reduction gearbox positioned longitudinally between the parking brake and motor on one side, and the differential on the other side;
- wherein the longitudinally positioned driveshaft extends along a lateral side of the motor;
- wherein the parking brake includes a disk that partially extends across a longitudinal side of the motor;
- and
- wherein the speed reduction gearbox is positioned on a second longitudinal side of the motor.

A method of operating an electrified drivetrain of a vehicle, comprising:
- operating a motor of a parking brake in a first direction to engage the parking brake with the electrified drivetrain and a second direction to disengage the parking brake from the electrified drivetrain, the electrified drivetrain including a traction motor rotating about a motor axis, the motor axis parallel with a longitudinal axis of the vehicle, a longitudinally positioned driveshaft engaging an input of a differential, where the parking brake is laterally offset on an opposite side of the longitudinally positioned driveshaft from the traction motor, the electrified drivetrain further including a speed reduction gearbox, the speed reduction gearbox positioned longitudinally between the parking brake and traction motor on one side, and the differential on the other side;
- wherein the longitudinally positioned driveshaft extends along a lateral side of the motor;
- wherein the parking brake includes a disk that partially extends across a longitudinal side of the motor;
- and
- wherein the speed reduction gearbox is positioned on a second longitudinal side of the motor.
