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.

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： A power divider unit including an input shaft, a drive gear disposed around the input shaft, an inter-axle differential assembly coupled to the input shaft, an output side gear coupled to the input shaft, and a locking system for the power divider unit. The locking system is configured to passively lock the inter-axle differential assembly. The locking system includes a ramped first clutch member in selective engagement with the drive gear, a mating second clutch member configured to engage the first clutch member, a clutch pinion, and a slip clutch assembly. The second clutch member and the first clutch member rotate at different speeds, the clutch pinion rotates and causes the slip clutch assembly and second clutch member to rotate at a speed of the input shaft, causing the first clutch member to mate with the first clutch member.

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 parking mechanism for use in a vehicle and method of operation thereof. The parking mechanism includes one or more actuation mechanisms, a parking pawl and a parking gear. At least a portion of the one or more actuation mechanisms are drivingly connected to at least a portion of a cam. The parking pawl has one or more parking pawl teeth extending therefrom that are selectively engagable with at least a portion of one or more parking gear teeth extending from an outer surface of a body portion of the parking gear. The parking pawl also includes a parking pawl pin aperture having a size and shape needed to receive and/or retain at least a portion of a parking pawl pin therein.

摘要： An axle assembly includes a carrier housing, a ring gear disposed within the carrier housing, and a pinion meshed with the ring gear. The pinion is coupled with a pinion shaft rotatably supported in the carrier housing by at least one bearing. A sump and a fluid catch are disposed in the carrier housing. A conduit having a regulator is in fluid communication with the fluid catch and the at least one bearing.
