Presented are finger-proof electrical terminals for battery assemblies, methods for making/using such electrical terminals, and vehicles with battery modules having finger-proof electrical terminals for bolted busbar connections. A battery assembly includes one or more electrochemical battery cells and one or more electrical terminals each electrically connected to the battery cell(s) and having a contact face to electrically connect the battery assembly to an electrical connector. A threaded nut attaches each electrical terminal to one of the electrical connectors. An electrically insulating nut cap is attached to each threaded nut. A battery housing, which stores therein the battery cell(s), includes an electrically insulating housing wall with one or more terminal jackets each mounting therein one of the electrical terminals. Each terminal jacket has a jacket window that circumscribes one of the nut caps, spaced therefrom by a predefined clearance sufficient to expose the contact face of the electrical terminal.

A motor stator includes a plurality of stacked annular stator laminates defining a stator core having a plurality of stator teeth on an inner diameter thereof, at least some of the plurality of stator laminates including a plurality of coolant openings therethrough. The plurality of coolant openings of adjacent stator laminates communicate with one another in order to define cooling channels inside the stator core. At least some of the plurality of stator laminates include the plurality of coolant openings including a plurality of generally circumferentially extending slots.

A method of forming a stator assembly, including providing a stator with a plurality of slots and a plurality of conductors configured to be inserted into the plurality of slots. The method includes obtaining a respective first shape for the plurality of conductors such that the plurality of conductors in the respective first shape forms concentric arcs sharing a common center. Obtaining the respective first shape includes forming a respective first portion, a respective second portion and a respective turn portion between the respective first portion and respective second portion. The method includes obtaining a respective second shape for the plurality of conductors, including: bending the respective first portion at a respective first bend to obtain a respective first leg and a respective first arm, and bending the respective second portion at a respective second bend to obtain a respective second leg and a respective second arm.

An integrated gear assembly includes a conjoined carrier assembly coupling a reducing gear set to a differential gear set. This includes first, second and third coaxial sun gears. The first sun gear meshingly engages first gear elements of stepped pinion gears of the reducing gear set. The second sun gear meshingly engages third pinion gears of the differential gear set. The third sun gear meshingly engages fourth pinion gears of the differential gear set. The third pinion gears of the differential gear set axially overlap second gear elements of the stepped pinion gears of the reducing gear set. The fourth pinion gears of the differential gear set axially overlap the third pinion gears of the differential gear set.

Integrated gear assembly

A vehicle and a locking assembly are disclosed. The locking assembly includes a pawl rotatable about a pivot axis between an engaged position and a disengaged position. The pawl is adapted to engage the ring gear when in the engaged position for preventing movement of the ring gear. The locking assembly further includes an actuator selectively actuated to move the pawl to the engaged position. Additionally, the locking assembly includes a biasing mechanism engaging the pawl to continuously bias the pawl toward the disengaged position. The pawl includes a first tooth and a second tooth spaced from each other to define a gap therebetween. The first tooth and the second tooth are adapted to trap a tooth of the ring gear in the gap when the pawl is in the engaged position for preventing rotation of the ring gear.

Vehicle and a locking assembly for the vehicle

An electric drive for a vehicle includes an electric motor and a planetary gear assembly including a sun gear drivingly connected to a rotor of the electric motor. A ring gear of the planetary gear assembly is connected to a brake that can be released to provide the system with a disconnect. A first transfer gear is connected to the planetary carrier. A second transfer gear is drivingly engaged with the first transfer gear and rotatable about a second axis offset from an axis of the electric motor. A differential is drivingly connected to the second transfer gear and provides drive torque to a pair of drive shafts along the second axis.
