  • Wheel driving method and system
    Patent number: 12370999
    Abstract: Methods and systems for operating a driveline that includes a cardan joint are described. In one example, electric machine torque is adjusted in response to driver demand torque and a torque to compensate for cardan joint rotation. The electric machine torque adjustments operate to cancel driveline torque variation that may be induced via the cardan joint.

  • AXLE ASSEMBLY WITH A FLUID RESERVOIR
    Publication number: 20240392874
    Abstract: Systems and methods for storing a working fluid in a fluid reservoir assembly. The fluid reservoir assembly includes, in one example, an axle tube circumferentially surrounding an axle shaft in a beam axle, a sleeve coupled to the axle tube, and a fluid reservoir containing a working fluid and formed in a cavity between an exterior surface of the axle tube and an interior surface of the sleeve. In the fluid reservoir assembly, the fluid reservoir is configured to fluidically connect to a component.
