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： 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.

摘要： Systems and methods are provided herein for operating a vehicle in a vehicle yaw mode. In response to initiating vehicle yaw mode, the system engages an open-loop mode, that provides open-loop forward torque to the outer wheels of the vehicle and open-loop backward torque to the inner wheels of the vehicle until a sufficient number of wheels are slipping. In response to determining that a sufficient number of wheels are slipping, engaging a closed-loop mode. While operating in the closed-loop mode, one or both of the wheel rotation and vehicle yaw rate are monitored to adjust the torques provided to the wheels of the vehicle to control the vehicle yaw rate.

摘要： An automotive vehicle with a storage compartment has a cabin, a set of rear wheels located behind the cabin, a cargo space, and a closable integrated storage compartment located adjacent to the cabin, rearward of a rear-most seat of the automotive vehicle, and forward of the set of rear wheels. At least a portion of the storage compartment is positioned forward of a forward wall of the cargo space. The storage compartment has at least one sidewall enclosing an interior portion of the storage compartment and extending from a first side panel at a first side of the automotive vehicle toward a second side of the automotive vehicle, a first opening to the storage compartment at the first side of the automotive vehicle, and a first door at the first opening. The first door has a first step member with a horizontal step surface when open.

摘要： A drivetrain system includes a first drive gear driven by a first motor and a second drive gear driven by a second motor. The first drive gear and the second drive gear are arranged along the axis. The first drive gear includes a first extension and the second drive gear includes a second extension arranged radially within and axially overlapping the first extension. The drivetrain system includes a system of bearings arranged between the first drive gear and the second drive gear, either drive gear and a stationary component, or a combination thereof. In some embodiments, the drivetrain system includes a clutch assembly arranged between the first drive gear and the second drive gear that interfaces to the first drive gear and to the second drive gear. The clutch assembly allows the drive gears to be locked or otherwise engaged to improve torque transfer.

摘要： An input gear assembly in which the input gear is coupled to the input shaft via a pair of spaced-apart pilot regions of the input shaft. One of the pilot regions is disposed adjacent to one of the bearings used, with the pilot region formed in or on the input shaft itself and engaging a corresponding internal surface of the input gear. Another of the pilot regions is formed in the inner bearing raceway of another of the bearings used, with the pilot region formed as an elongate portion of the inner bearing raceway of the input shaft and engaging another corresponding internal surface of the input gear. For manufacturing simplicity, this additional pilot region and the remainder of the elongate inner bearing raceway have the same material properties, surface treatment, straightness, and cylindricity. This arrangement prevents tilting of the input gear with respect to the input shaft and bearing shaft, thereby enhancing performance.

摘要： A drive system includes a first drive train and a second drive train coupled by a differential assembly. Each drive train include a motor, an output gear, and a clutch assembly that engages and disengages the output gear from respective halfshafts. The differential assembly is configured to couple the first and second halfshafts, and connect/disconnect the first output gear and the first halfshaft. The differential assembly includes, for example, side gears, a spider gearset, and an actuator for engaging and disengaging the differential casing from the first output gear. A control system is configured to actuate actuators of clutch assemblies and/or a differential assembly to achieve one or more drive modes for each drive axis. The control system determines the first drive mode, controls the clutch assemblies and differential assemblies, and controls one or more motors. The drive modes include, for example, torque vectoring, fully locked, single motor, and neutral.

摘要： A drivetrain system includes a housing configured to at least partially contain a liquid lubricant such as oil that flows through a gearset. Within the housing is arranged a plurality of bearings configured to constrain respective trajectories of respective shafts. An inner surface of the housing includes a first region surrounding a motor gear bearing that is actively cooled by a coolant. The inner surface also includes a second region that is distal to the motor gear bearing and that is not actively cooled by the coolant. Cooling pins are arranged in the first region and are configured to provide heat transfer from the liquid lubricant to the coolant. The gear set can include more than one shaft, with at least one gear configured to splash oil onto the cooling pins to transfer heat from the liquid lubricant to a coolant flowing in a motor housing adjacent the first region.
