TRANSMISSION INTEGRATED POWER TAKE OFF FOR COMMERCIAL VEHICLE TRANSMISSION
A rear mount power take-off for a transmission includes a housing assembly configured to be mounted in an opening in the transmission. A power take-off shaft includes an externally splined end extending into an opening in the housing assembly and is configured to be driven by a component of the transmission. A guide sleeve is received in the housing assembly and includes an exterior shoulder opposing an interior retaining shoulder of the housing assembly, the guide sleeve further including an interior shoulder. A spring biases the guide sleeve against the interior retaining shoulder of the housing assembly. A coupler sleeve is secured to an interior of the guide sleeve and includes a first internal spline for selective engagement with the externally splined end of the power take-off input shaft and a second internal spline configured to engage a power take-off device.
VEHICLE DRIVE DEVICE
A rotary electric machine is disposed coaxially with an input member more toward a first side in an axial direction than a first gear that meshes with a second gear. A third gear rotates integrally with second and fourth gears that mesh with third gear more toward second side in axial direction than first and second gears. An axis of a counter gear mechanism is below axis of rotary electric machine and axis of differential gear mechanism. An inverter device more toward first side in axial direction than fourth gear and above axis of differential gear mechanism while that inverter device overlaps fourth gear as seen in axial direction. A specific portion of inverter device is between rotary electric machine and fourth gear in axial direction, such that specific portion overlaps counter gear mechanism as seen in up-down direction and overlaps rotary electric machine as seen in axial direction.
Hybrid vehicle drive device
A hybrid vehicle drive device includes a transmission coupled to the engine output shaft of an engine, a final reduction gear coupled to the transmission output shaft of the transmission, a drive shaft coupled to the final reduction gear, and a power transmission mechanism that transmits the rotation of an electric motor to the final reduction gear. The hybrid vehicle drive device includes a transaxle case accommodating the transmission, the final reduction gear and the power transmission mechanism and having a mounting surface for mounting the engine and the electric motor. The transaxle case is formed by an engine-side converter housing, a transmission-side transmission case, and a middle wall attached to the converter housing and separating the converter housing from the transmission case, the power transmission mechanism being housed between the converter housing and the middle wall.
DIFFERENTIAL LOCK/UNLOCK POSITION DETECTION
A sensor assembly configured for use with a locking differential received in a differential case includes a sensor housing, a switch element and a sense element. The sensor assembly is configured to determine a position of an armature in relation to a stator. The armature moves relative to the stator between engaged and disengaged positions corresponding to the locking differential being in a locked and unlocked state. The sensor housing is coupled relative to the differential case of the locking differential. The switch element is disposed in the sensor housing. The sense element moves with the armature. The sensor assembly is configured to change state based on a position of the sense element.
Hybrid drive transmission with E-motor rotor resolver integrated with auxiliary drive
A transmission with an integrated hybrid drive is provided that includes a transmission housing as well as a torque converter rotatably mounted within the transmission housing. The torque converter includes an outer shell configured to be drivingly connected to a crankshaft. An e-motor is integrated into the transmission and includes a stator connected to the transmission housing, a rotor connected to the outer shell, and a controller. An auxiliary drive unit is provided having a drive shaft that is driven by a connection to the torque converter outer shell. A rotor position sensor (RPS) is provided on the drive shaft that is configured to signal rotor position data to the controller. The drive shaft and RPS are offset relative to the axis of the rotor and torque converter, providing better space utilization.
Pinion assembly preloading system
The present disclosure relates to pinion assembly preloading systems and methods of operation. Disclosed are systems including a press actuator that applies an axial force against a pinion assembly; a force sensor that measures a reaction force at the pinion assembly; and a method of controlling the press actuator according to a change in the reaction force.
Rotary-member lubricating structure
A rotary-member lubricating structure includes a housing, a baffle portion, a support portion, and a bolt. The baffle portion has a shape conforming to a shape of a rotary member included in a speed-changing mechanism and covers the rotary member to collect or discharge scattered lubricating oil. The baffle portion includes a first partial baffle portion provided on a first side of the rotary member and a second partial baffle portion provided on a second side of the rotary member. The first partial baffle portion has a protrusion protruding radially outward from an outer circumference of the baffle portion and a fastening hole provided in the protrusion and extending through the first partial baffle portion in an axial direction of the rotary member. The second partial baffle portion has a filling portion to fill a recess in the first partial baffle portion provided due to the protrusion.
MASKING PLUG FOR COLD SPRAY REPAIR AT COUNTERBORE HOLE
A method of improving a structure of a component adjacent a feature is provided including removing a portion of the structure including at least one area where damage of corrosion has occurred or is likely to occur to expose a surface of the structure. A masking plug is installed into the feature such that a base of the masking plug is coupled to a first portion of the feature and a head of the masking plug is arranged adjacent a second portion of the feature. A structural deposit is formed on the surface and is integral with the structure. Excess material of the structural deposit and a portion of the head of the masking plug is removed. The second portion of the feature is reformed and the masking plug is removed from the feature.
Gear systems having bearing flexure mounted thrust bearings
A gear system includes a gear assembly having a shaft that is at least partially disposed within a housing of the gear system. A thrust bearing has inner and outer races with the outer race coupled to the housing. A bearing flexure is disposed between the inner race of the thrust bearing and the shaft. The bearing flexure includes a cylindrical cage having at least one shaft journal ring and a plurality of circumferentially distributed axially extending fingers coupled thereto with the shaft journal ring coupled to the shaft. A cylindrical bearing journal has inner and outer surfaces with the outer surface coupled to the inner race of the thrust bearing. Each of a plurality of circumferentially distributed radially extending struts extends between one of the fingers and the inner surface of the cylindrical bearing journal. The bearing flexure has an axial stiffness that is greater than its radial stiffness.
LINEAR EXPANSION REDUCTION OF METAL COMPONENT ASSEMBLIES USING COMPOSITES
Methods of producing an assembly, e.g., a bearing assembly, for a vehicle, with reduced thermal expansion in a linear direction as well as methods for minimizing linear thermal expansion in an assembly, are provided. The assembly has at least two components with substantially different linear coefficients of thermal expansion (CLTEs). The assembly has a lightweight planar metal component (e.g., a housing) with a first CLTE, a second component (e.g., a bearing component) having a second CLTE, and a polymeric composite with a third CLTE. The first CLTE is greater than the second CLTE. The third CLTE is less than or equal to the second CLTE, so that the polymeric composite structure attached to the first planar metal component reduces thermal expansion of the first planar metal component in at least one linear direction and minimizes separation of the second surface of the first planar metal component from the second component.
