摘要： Methods and systems for an electric drive assembly are provided herein. In one example, an electric drive system is provided that includes two multi-motor drive units with associated planetary gear reductions that have asymmetric gear ratios. The planetary gear reduction in each drive unit includes a ring gear and a sun gear that are rotationally coupled to a pair of motors and a carrier rotationally coupled to an output gear that interfaces with a gear reduction of an axle assembly.

摘要： Methods and systems for an electric drive assembly are provided herein. In one example, a method for operation of an electric drive system is provided that includes coordinating operation of a first electric drive unit and a second electric drive unit based on a first power request. In the system, each of the first and second electric drive units include a planetary gear reduction that delivers power from a pair of motors to a set of axle shafts, and the planetary gear reductions have asymmetric gear ratios.

摘要： A system is provided for shielding a tone ring assembly in automotive vehicles. The system comprises a ring cap with a central aperture, a plurality of molding slides circularly arranged on a first side of the ring cap, a plurality of snap-fit arms and a plurality of pilot tabs positioned on a second side of the ring cap, where the plurality of pilot tabs and the plurality of snap-fit arms are arranged in concentric circles with the snap-fit arms forming an outer circle and the pilot tabs forming an inner circle, and where each pilot tab of the plurality of pilot tabs is positioned directly behind a corresponding snap-fit arm of the plurality of snap-fit arms. In one example, the system prevents metal to metal contact between a tone ring and a shaft during axle shaft installation.
