Abstract: A propeller shaft for transmitting driving force of a vehicle includes a first shaft unit mounted to the vehicle via a vehicle mounting member. The first shaft unit includes a sleeve yoke, a stub shaft, and a tube. The sleeve yoke is connected to an output shaft of a transmission of the vehicle, and receives the driving force via the output shaft. The stub shaft is disposed oppositely to the sleeve yoke in a direction of a rotational axis of the first shaft unit. The tube connects the sleeve yoke and the stub shaft. The stub shaft includes a weakest part structured to be less in torsional strength than a remaining part of the first shaft unit and formed at a position at which the stub shaft overlaps with the vehicle mounting member in the direction of the rotational axis.

Abstract: An apparatus and methods are provided for a modular front drivetrain comprising a single assembly that may be installed onto and removed from a vehicle. The modular front drivetrain comprises a modular chassis supporting a transaxle, a front differential, and a steering gear for operating front wheels of the vehicle. The transaxle, the front differential and drive axles convey torque from an engine onboard the vehicle to the front wheels. A spindle assembly is coupled with each front wheel of the vehicle and pivotally joined with the modular chassis by way of a front suspension system. Steering rods coupled with the spindle assemblies horizontally rotate the front wheels according to operation of a steering wheel onboard the vehicle. The modular front drivetrain advantageously facilitates replacing an entire drivetrain and suspension assembly quickly and easily in the event of a part failure during racing applications.

Abstract: A self-energy-storage wheel corner module integrating omni-directional redundant steering and energy regenerative suspension, including a wheel assembly, a suspension system having an unequal-length double wishbone suspension structure, a first steering system, a drive system, a braking system, a second steering system, an energy storage system and an actuator assembly. The first steering system is a primary steering system, and has low steering delay and excellent maneuverability at high speeds. The second steering system is a redundancy of the first steering system, and contributes to the omni-directional steering of the wheel assembly, which enhances the vehicle maneuverability. A motor of the second steering system also functions as another actuation motor of the actuator assembly in an idle state to enable the suppression and energy regeneration of the suspension vibration.

Abstract: A drive device has two electric drive machines for distributing the torque between two wheels of an axle of a motor vehicle and an inverter unit which is electrically connected to the drive machines for converting an electrical DC signal into a drive-machine-specific electrical AC signal. The two drive machines are arranged spaced apart from one another in the axial direction to form an intermediate space, and components of the inverter unit are arranged in a first area, located in the intermediate space and oriented in a first direction transversely with respect to the axial direction, of the drive device, and in a second area, adjoining the intermediate space and oriented parallel to the axial direction, of the drive device, to form a low-inductance, T-shaped inverter architecture.

Abstract: A computer system including a processor device configured to adjust a torque applies to a first wheel to a vehicle is provided. The processor device is configured to estimate, a variation in rotational speed of a first drive shaft. The first drive shaft is driven by a second drive shaft by rotating a mechanical joint. The mechanical joint is drivingly connected to both the first drive shaft and the second drive shaft. The processor device is configured to, based on the variation in rotational speed of the first drive shaft and a current speed of the vehicle, estimate a target slip for the first wheel. The processor device is further configured to, based on the estimated target slip for the first wheel, adjust the torque applied to the first wheel.
