Abstract
The drivetrain system includes an I shield, two motors, two A-shields, and a gearset. Each A-shield is affixed to a respective one of the two motors, and each A-shield is also affixed to the I-shield. The gearset includes a motor shaft of one of the motors and a motor gear affixed to the motor shaft. Three motor bearings are arranged co-linearly and coupled to the motor shaft. The gearset also includes an intermediate shaft and a wheel gear affixed to the intermediate shaft and engaged with the first motor gear. A pinion gear is also affixed to the intermediate shaft. Two intermediate bearings are arranged co-linearly and coupled to the intermediate shaft. The gearset also includes a drive shaft and a drive gear affixed to the drive shaft and engaged with the first pinion gear. The motor shaft, intermediate shaft and drive shaft form a shaft angle that may allow compactness.
