  • Patent number: 11473650
    Abstract: A method of operating a shifting system for a vehicle transmission includes engaging a clutch to operatively couple one of first and second gear ratios to an input member, and moving a disconnect from a first disconnect position where a disconnectable component is disengaged from the disconnect, to a second disconnect position where the disconnectable component is engaged with the disconnect to operatively couple the other of the first and second gear ratios to the input member through a shifting assembly. Engaging the clutch and moving the disconnect are performed such that the clutch is operatively coupled to one of the first and second gear ratios at the same time that the shifting assembly is operatively coupled to the other one of the first and second gear ratios, thus preventing torque from being transmitted through either the first and second gear ratios of the vehicle transmission to park the vehicle.

  • Patent number: 11469630
    Abstract: Rectangular conductor wires are often used in alternator applications requiring a high slot fill to maximize output and efficiency. However for lower output and efficiency applications, round conductor wire may increase cost competiveness in these alternators. A common lamination for a core alternatively accommodates both rectangular conductor wires and round conductor wires for different applications without any other component changes. The lamina has a slot that aligns round wire in a single row within the slot and provides a predetermined clearance from the slot opening. A stator core formed from these laminae has a relatively high slot fill factor when wound with the round wire. The same stator core can be alternatively wound with square wire to increase the slot fill factor even higher. The common lamination results in two stator configurations: a high slot fill version (round wire) and a very high slot fill version (square wire).

  • Patent number: 11454142
    Abstract: An electrically-actuated variable camshaft timing (VCT) phaser is employed for use with an internal combustion engine (ICE). The electrically-actuated VCT phaser includes a gear set assembly and a fixture. The gear set assembly has an input gear and an output gear, among other possible components. The input gear receives rotational drive input from an engine crankshaft, and the output gear transmits rotational drive output to an engine camshaft. The fixture is secured in the gear set assembly. Amid installation of the electrically-actuated VCT phaser on the ICE, the fixture constrains rotational movement of the gear set assembly. After installation, the fixture can be removed from the gear set assembly.
