    摘要: 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.

    摘要: Disclosed embodiments include systems, vehicles, and methods for determining a quantity of energy expendable in charging a towed vehicle while it is towed. In an illustrative embodiment, a computing system transportable aboard at least one of a towing vehicle and a towed vehicle includes computer-readable media storing computer-executable instructions configured to identify a quantity of charging energy to be supplied to at least one power cell of the towed vehicle by at least one rotating electromagnetic device of the towed vehicle generating and supplying electrical power to charge the at least one power cell of the towed vehicle while the towed vehicle is towed by the towing vehicle. The computer-executable instructions are also configured to determine a quantity of towing energy expendable by the towing vehicle in towing the towed vehicle to provide the quantity of charging energy to the at least one power cell of the towed vehicle.

    摘要: A dual drive unit may include two motors, two power transfer mechanisms, and two output shafts. The output shafts are co-linear. The dual drive unit may include two single drive units, which may be similar to each other, coupled together at a joint, which may optionally include a clutch. A drive unit may be modular, and various components may be combined to provide power to an output shaft. For example, a drive unit may include a differential at a first interface, which may be removable, and two drive units may be coupled together at the first interface. A drive unit may have a Z configuration, wherein a motor on a first side of a vehicle powers a wheel on an opposite side of the vehicle.
