Abstract: Railcar inspection systems, methods, and apparatuses are disclosed, including a railcar inspection portal. The railcar inspection portal includes a physical structure positioned around a railroad track, and through which a railcar can travel. The railcar inspection portal can include wheel detection sensors along the railroad track for detecting the presence of a railcar passing over the sensors. The sensors can transmit signals, corresponding to railcars passing over the sensors, to computing devices for determining railcar speeds. The railcar inspection portal can include imaging devices configured to capture images and readings of railcars passing through the inspection portal. Based on a determined speed corresponding to a passing railcar, the computing devices can control the imaging devices to capture specific areas or components of the passing railcar, or individual cars thereon.

Abstract: A drive arrangement for a torque converter is disclosed herein. The drive arrangement includes a first drive plate element configured to be connected to a torque converter cover and configured to secure a rotor of an electric motor against the torque converter cover. A second drive plate element is configured to be connected to a flex plate, and the first and second drive plate elements are connected to each other.

Abstract: An emotor connection arrangement for connecting power electronics of an electric or hybrid electric vehicle to an emotor. The emotor connection arrangement includes a junction box configured to extend from the power electronics to the emotor, and phase bars that extend in the junction box and electrically connect the power electronics to the emotor. A first access cover is removably connected to the junction box and configured to provide access for connecting the phase bars to the emotor, and a second access cover provides similar access for connecting the phase bars to the power electronics. In order to prevent overheating, the first access cover includes a cooling fluid channel with a cooling fluid inlet configured to be connected to a cooling fluid source and a cooling fluid outlet configured to be connected to a cooling fluid return.

Abstract: A generator module for a vehicle includes a housing with a first conical surface, a rotor assembly with a second conical surface, aligned with the first conical surface, and a spring arranged to push the second conical surface into contact with the first conical surface. In an example embodiment, the first conical surface or the second conical surface includes a plastic surface or a friction paper surface. In an example embodiment, the rotor assembly is axially displaceable within the housing to compress the spring and move the second conical surface away from the first conical surface.

Abstract: The disclosures herein relate to the design of one or more battery monitoring or maintenance devices in some embodiments including guidance for autonomous vehicles for recharging, service or replacement of batteries or related devices. These devices may include but are not limited to devices that monitor and/or maintain the health of batteries or related devices that monitor and/or maintain the health of assets. The devices include batteries for vehicles, oral cleaning devices, smart-clothing with integrated batteries and sensors and charging pads which may monitor the health or assets being charged. Sensors may be integrated in these devices including but not limited to IMUs, thermocouples or oral cleaning devices, IMUs in clothing like shoes or wrist bands, or timers or charging sensors in magnetic surfaces which may cause one or more objects and/or other magnetic surfaces to float when a desired function is achieved.

Abstract: A plastic coolant fitting for a hybrid module includes an upper coolant tube with a first straight section and a rounded section, and a lower coolant tube with a second straight section fixed to the rounded section by spin welding. The rounded section may include a ring-shaped groove and the second straight section may include a ring-shaped protrusion installed in the ring-shaped groove. Prior to spin welding, the ring-shaped groove and the ring-shaped protrusion may include respective complementary trapezoidal cross-sections.

Abstract: A hybrid drive assembly is provided having a hybrid drive housing with an electric motor and a disconnect clutch therein. A transmission is connected to the hybrid drive housing and a torque converter is provided between the electric motor and the transmission. A baffle extends radially between the torque converter and the hybrid drive housing. The baffle includes a ring-shaped body that is affixed to the hybrid drive housing and extends completely around a transmission side periphery of the hybrid drive housing. A fluid pathway is located on or in the baffle, and orifices extend from the fluid pathway toward the electric motor. A fluid inlet port is connected to the fluid pathway, and a fluid connection is provided from a pressurized fluid source to the fluid inlet port. This allows fluid circulated by a pump within the transmission, to be sprayed on the electric motor for cooling.

Abstract: A torque converter, including: a cover arranged to receive torque; a pump including a pump shell connected to the cover, and pump blades; a turbine in fluid communication with the pump and including a turbine shell and turbine blades; a stator including stator blades disposed between the turbine and the pump; a pump hub non-rotatably connected to the pump shell and including a first planar surface facing radially outward with respect to an axis of rotation; and a resolver rotor non-rotatably connected to the pump hub and including a second planar surface in contact with the first planar surface and facing radially inward with respect to the axis of rotation.
