    Abstract: An axial flux motor having a stator and a rotor disposed about a rotational axis adjacent the stator defining an air gap therebetween. The rotor includes a disk having an interior face oriented toward the stator and an opposite exterior face; a plurality of magnets affixed in a predetermined arrangement on the interior face of the disk; a back plate abutting the exterior face of the disk, and a segmented cage fitted onto the interior face. The back plate includes a circumferential edge surface defining a plurality of notches. The segmented cage includes a plurality of retainer ribs configured to retain the magnets in the predetermined arrangement on the interior face of the disk. The segmented cage cooperates with the back plate to structurally support the disk therebetween, thereby inhibiting the disk from flexing in an axial direction.

    Abstract: A turbocharging system for an internal combustion engine includes a turbocharger having a shaft supported for rotation about an axis. The turbocharger also includes a turbine wheel mounted on the shaft and configured to be rotated about the axis by the exhaust gas, and a compressor assembly mounted on the shaft and configured to pressurize an airflow received from the ambient for delivery to the cylinder. The turbocharging system additionally includes an electric motor configured to generate electric motor torque. The turbocharging system further includes a one-way clutch configured to selectively connect the electric motor to the compressor assembly, such that the electric motor torque assists the turbocharger in generating boost pressure. An internal combustion engine employing such a turbocharging system is also disclosed.

    Abstract: A torque transmitting device (10) includes a clutch housing (14) rotatable about an axis (A), a first set of clutch plates (20A) splined to the clutch housing (14), and a second set of clutch plates (20B) interleaved with the first set and rotatable about the axis (A) of rotation. A push plate assembly (28) is splined to the clutch housing (14) for rotation therewith. A roller assembly (42) includes a roller housing (48) splined to the clutch housing (14), a roller supporter (54) housed in the roller housing (48), and a roller element (62) supported by the roller supporter (54). A wedge assembly (12) includes a wedge housing (64) connected to a wedge block (24). The wedge housing (64) includes a ramp member (70) defining a ramp surface (16) with the roller element (62) contacting the ramp surface (16). A motion converter (71) is disposed between the push plate assembly (28) and the wedge housing (64) such that axial movement of the push plate assembly (28) causes rotation of the wedge assembly (12) relative to the roller assembly (42).

    Abstract: Vehicles and methods are provided for monitoring the health of a substrate and a protective coating disposed on the substrate. A vehicle includes a substrate, a protective coating, a coating deformation sensor, and a controller. The protective coating is disposed overtop the substrate. The coating deformation sensor is operatively coupled with the protective coating and configured to measure a deformation value of the protective coating. The controller is configured to: determine a deformation recovery rate of the protective coating based on the deformation value; determine whether the deformation recovery rate corresponds with an expected recovery rate of the protective coating; and indicate that the protective coating may be impaired in response to determining that the deformation recovery rate does not correspond with the expected recovery rate.

    Abstract: An actuation system for actuating a clutch piston of a transmission includes an actuator and a lever. A first end of the lever is attached to the actuator. The lever is pivotable about a lever connection location. Movement of the actuator rotates the lever about the lever connection location. A spring assembly is pivotable about a spring connection location, and pivotably connected to the lever at a second end of the lever. When the actuator is disposed in an un-actuated position, the spring assembly is positioned such that a pre-loaded spring force is directed along a zero moment path to generate a zero moment in the lever. When the actuator is disposed in an actuated position, the spring assembly is rotated so that the spring force is directed along a moment generating path in order to generate a moment in the lever to rotate the lever.

    Abstract translation: 用于致动变速器的离合器活塞的致动系统包括致动器和杠杆。 杠杆的第一端连接到执行机构。 杠杆可绕杠杆连接位置枢转。 执行器的移动使杠杆绕杠杆连接位置旋转。 弹簧组件可围绕弹簧连接位置枢转，并且在杠杆的第二端处可枢转地连接到杠杆。 当致动器设置在未致动位置时，弹簧组件被定位成使得预加载的弹簧力沿着零力矩路径被引导以在杠杆中产生零力矩。 当致动器设置在致动位置时，弹簧组件被旋转，使得弹簧力沿着力矩产生路径被引导，以便在杠杆中产生转动杠杆的力矩。
