Abstract: An internal combustion engine (12) having a crankshaft (20) is coupled to a transmission (14) through an assembly (10) comprising a rotary electric machine (16) and an engine disconnect clutch (17). The stator (38) and rotor (40) of the machine are separated by a radial air gap (42), and the machine is selectively operable as an electric motor to source torque to the powertrain and as an electric generator, or alternator, to sink torque from the powertrain. The organization and arrangement provides a powertrain and method of making a powertrain for establishing and maintaining precision in the radial air gap to secure optimal efficiency of machine operation on a production basis.

Abstract: An installation and support apparatus or assembly 18 is provided for use in combination with an electric machine 10, such as a starter-alternator, which is adapted to be operatively installed between the engine block 12 and the transmission assembly 16 of a vehicle. The apparatus 18 includes a stationary support member or member 20, an inner or crankshaft engaging bearing 22, and an outer or rotor engaging bearing 24. Member 20 cooperates with bearings 22 and 24 to automatically create or form a relatively precise and uniform gap 54 between the stator assembly 26 and the rotor assembly 30 of electric machine 10, and further provides independent and additional support to the electric machine 10 and the vehicle's crankshaft 14.

Abstract: A rotor of an electric motor for a motor vehicle is aligned to an axis of rotation for a crankshaft of an internal combustion engine having an internal combustion engine and an electric motor. A locator is provided on the crankshaft, a piloting tool is located radially by the first locator to the crankshaft. A stator of the electric motor is aligned to a second locator provided on the piloting tool. The stator is secured to the engine block. The rotor is aligned to the crankshaft and secured thereto.

Abstract: An electromagnetically actuated valve for an automotive vehicle includes a pole assembly having a coil situated therein and a combination valve element and armature, including a tubular axially moveable valve spool for controlling the flow through at least one inlet port and at least one outlet port. A magnetic head having a first end attached to an end of the valve spool and a second end nested within a relieved area provided in the pole assembly functions to move the tubular valve spool in response to magnetic flux induced by the coil.
