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.

Drive plate configuration for torque converter

A torque converter centering sleeve assembly is disclosed herein that includes an anti-contamination plate. The assembly includes a centering sleeve including a body. A plate, i.e. an anti-contamination plate, is arranged inside of the centering sleeve. The plate includes at least a first portion and a second portion in contact with an inner surface of the centering sleeve such that the plate partitions off a pocket defined by the centering sleeve. The plate can be secured to the centering sleeve via a snap fit or press fit.

Torque converter anti-contamination plate

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. The pump hub includes a protrusion extending radially outward from the first planar surface and in contact with the resolver rotor. The resolver rotor is arranged to determine a rotational position of the torque converter around the axis of rotation.

Torque converter with resolver rotor having angular and axial locking

A method for manufacturing a thrust washer is provided in which a phenolic resin layer is bonded directly to a bearing surface of the base material using two presses at an elevated temperature and pressure.

Thrust bushing surface layer using directly bonded heat activated nitrile-phenolic adhesive film

A housing for a torque converter comprising: an axis of rotation; a cover including: a first inner surface; a first outer surface opposite the first inner surface; a first axially extending necked portion radially outward relative to the axis of rotation and parallel to the axis of rotation, an impeller shell non-rotatably connected to the cover and having: a second inner surface; a second outer surface opposite the second inner surface; a second axially extending necked portion radially outward relative to the first axially extending necked portion; a line orthogonal to the axis of rotation passes through the first and second axially extending necked portions; and, a weld fixedly securing the first inner surface to the second inner surface at at least one point on the line. A torque converter including such a housing closure is also described.

Reduced volume torque converter having inverted cover closure

A layer is provided for a thrust bushing, for example a torque converter thrust bushing. A phenolic resin is bonded directly to a bearing surface of a rotating component to form the layer without any substrate.

An electric axle assembly is disclosed. The electric axle assembly includes a common housing with an electric motor, a continuously variable transmission, and a planetary differential. The electric motor includes an output shaft and the continuously variable transmission is connected to the output shaft. The continuously variable transmission includes a drive shaft configured to be variably driven by the output shaft. The planetary differential is connected to the drive shaft, and the planetary differential includes a carrier configured to be driven by the drive shaft and dual sun gears configured to be driven by the carrier. Wheel axles are in independent driving engagement with a respective one of the dual sun gears.

Electric axle assembly

A clutch carrier includes a stamped carrier and a hub portion. The stamped carrier has a first circumferential wall, a second circumferential wall axially and radially offset from the first circumferential wall, and a first radial wall extending radially inward from the second circumferential wall. The hub portion has a third circumferential wall extending from the first radial wall, a fourth circumferential wall axially and radially offset from the third circumferential wall, and a second radial wall connecting the third and fourth circumferential walls. In some example embodiments, the first circumferential wall includes a plurality of axially extending fingers for driving engagement with a clutch plate. In an example embodiment, each of the plurality of axially extending fingers includes a groove for receiving a retaining ring.

Clutch carrier assembly

A planetary differential continuously variable transmission is provided having a first drive input ring gear having internal teeth, and a planetary differential connected to the first drive input ring gear, A first electric machine is provided having a first stator and a first rotor, with the first rotor being connected to the first drive ring input ring gear. A second electric machine is provided having a second stator and a second rotor, with the second rotor being connected to the planet gear carrier of the planetary differential and acts as a second drive input. A one way clutch is located between the second stator and the second rotor to limit a reverse rotation of the second rotor in order to improve efficiency and save battery life in electric or hybrid vehicles with this drive system.

Planetary differential CVT with anti-freewheel one way clutch

A CVT (continuously variable transmission) differential is provided which includes a first drive input ring gear having internal teeth. A planetary or bevel gear differential is connected to the first drive input ring gear. The planetary differential includes a planet gear carrier, first planet gears, second planet gears, a first sun gear, and a second sun gear. Alternatively, the bevel gear differential includes a carrier that supports drive and driven bevel gears. A second drive input is connected to the planet gear carrier or bevel gear carrier. Preferably, a primary drive is connected to the first drive input ring gear, which can be an internal combustion engine or an electric motor. Preferably, a secondary drive is connected to the second drive input, which is preferably an electric motor, for example for a hybrid motor vehicle.
