摘要： An apparatus for correcting an imbalance in a rotating shaft along with a method for correcting the imbalance in a rotating shaft is identified. The apparatus includes a joint assembly having a first joint member that is drivingly connected to a second joint member by one or more third joint members. At least a portion of a first shaft may be drivingly connected to at least a portion of the first joint member and at least a portion of a second shaft may be drivingly connected to at least a portion of a second end portion of the second join member. A boot can may be connected to at least a portion of a first end portion of the second joint member. One or more balancing elements may then be connected to at least a portion of the boot can and/or the second joint member of the joint assembly.

摘要： Methods and systems are provided for a disconnect assembly in an electric drive unit. In one example, the system includes a dog clutch positioned in a differential, configured to selectively mechanically decouple an electric motor from one or more drive wheels, and including a first interface designed to selectively engage a second interface. In such an example, each of the first interface and the second interface include a plurality of teeth, each tooth in the plurality of teeth includes a drive flank and a coast flank, and the coast flank has a first tooth angle greater than a second tooth angle of the drive flank.
