摘要： A battery module locating tool includes a support pillar and a plurality of fixtures supported on the support pillar. Each fixture is individually translatable along the support pillar and arranged to locate a battery cell according to a longitudinal datum and a lateral datum. The support pillar is movable toward and away from a battery frame onto which the battery cell is located.

摘要： A method for manufacturing a case-hardened ring gear/differential case assembly includes attaching a ring gear to a differential case. The case-hardened ring gear and the differential case are fabricated of materials each having differing properties of at least carbon content and melting temperature. The attaching includes placing a flange of the case-hardened ring gear in intimate contact with a flange of the differential case whereby a predetermined gap is defined between a remainder of the ring gear and a remainder of the differential case. The ring gear flange is attached to the differential case flange by a friction welding process. The predetermined gap defines an outflow channel that receives a carburized portion of the case-hardened ring gear as overflow material created by an upset forging step of the friction welding process. Differential assemblies and vehicles including such are described.

摘要： A method of manufacturing a hypoid gear includes face hobbing a gear blank and forming a green hypoid gear with gear teeth, heat treating the green hypoid gear to form a heat treated hypoid gear with heat treated gear teeth, and hard hobbing the heat treated gear teeth to form a hard finished hypoid gear. Critical non-tooth features on the heat treated hypoid gear are hard finished. Also, the critical non-tooth features on the heat treated hypoid gear can be hard finished prior to hard hobbing the heat treated gear teeth. The heat treating includes at least one of carburizing and induction hardening the green hypoid gear, a surface of the heat treated gear teeth has a hardness greater than or equal to 58 HRC, and the hard hobbing removes heat distortion from the heat treated gear teeth.

摘要： An apparatus for cutting electrode sheets includes a conveyor and a laser device. The conveyor is configured to move an original sheet including an electrode portion and an ear portion extending from an edge of the electrode portion. The laser device is configured to move a laser to cut out a tab connected to the electrode portion from the ear portion of the original sheet. The laser device is also configured to move the laser from one edge of the electrode portion to another edge of the electrode portion to cut and separate a respective electrode sheet including the tab from the original sheet. The laser is configured to cut out the tab from the ear portion and cut and separate the respective electrode sheet including the tab from the original sheet as the conveyor is moving the original sheet.
