TORQUE CONVERTER INCLUDING COVER FLUID FLOW BAFFLES
A torque converter is provided. The torque converter includes a cover. The cover includes a radially extending section and an axially extending section extending axially from an outer radial end of the radially extending section. The torque converter also includes at least one baffle assembly attached to the radially extending section or the axially extending section of the cover. The at least one baffle assembly includes a plurality of baffles protruding from the cover to impact fluid flow in the torque converter. Methods of forming a torque converter are also provided.
MULTISTAGE PISTON ACTUATOR
A multistage piston actuator exerts a driving pressure against a spring pressure into pressure chambers of piston bodies, fitted into a cylinder body, to operate the push rod. Each piston body is combined with a partition fitted into the cylinder body. Each piston body includes a pressure receiving plate portion, and an axial rod and a slidable cylindrical guide portion extending concentrically in opposite directions, the axial rod having an axial air passage connected to the pressure chambers. Each partition includes a base plate portion having a through-hole which receives the axial rod of an adjacent piston body, a large-diameter outermost cylindrical portion fitted into the cylinder body, and a slidable cylindrical guide portion slidably fit-engaged with the slidable cylindrical guide portion of the piston body. The axial rods of each piston body are brought into contact to operate the push rod.
RECESSED HYDRODYNAMIC BEARING FOR TURBINE DAMPER RIVETING
A drive assembly for a torque converter is provided. The drive assembly includes a turbine; a damper assembly fixed to a first side of the turbine by connectors; and a hydrodynamic bearing fixed to a second side of the turbine opposite the first side. The hydrodynamic bearing includes at least one recess formed therein receiving ends of the connectors. A method of forming a drive assembly is also provided. The method includes fixing a damper assembly cover plate to a first side of a turbine via connectors; and fixing a hydrodynamic bearing to a second side of the turbine opposite the first side. The hydrodynamic bearing including at least one recess formed therein receiving an ends the connectors. A torque converter is also provided.
Damper for motor vehicle torque transmission device
A damper for a motor vehicle torque transmission device, in particular of the long travel damper type, having a torque input element (22), a torque output element (28), at least one group (26) of differing elastic members (26a, 26b) mounted between the torque input element and torque output element and acting oppositely to the rotation of the torque input element (22) and torque output element (28) with respect to one another, the elastic members (26a, 26b) of the group of elastic members being arranged in series by means of a phasing member (30) so that the elastic members (26a, 26b) of the group (26) of elastic members deform in phase with one another, the group (26) of elastic members (26a, 26b) being received in a receptacle (44) that is asymmetrical with respect to a median radial plane of the receptacle (44).

PRESSURE SENSOR FOR POWER TAKE OFF
The present invention provides improved, real time sensing of pressure supplied to the hydraulic operator of a clutch for a motor vehicle driveline power take off. A proportional sensor in the hydraulic line to the power take off clutch actuator provides a data signal in real time of the actual pressure applied to the clutch actuator. This signal is provided to the power take off control module (PCM) and/or to the transmission control module (TCM). The power take off control module, having instantaneous data regarding the pressure applied to the hydraulic operator achieves two important operating functions: monitoring and feedback.
Hydrostatic thrust bearing
A torque converter comprising a stator including a base and an impeller including: an impeller shell; and, a hydrostatic thrust bearing. The hydrostatic thrust bearing comprising: a first bearing surface facing the stator; a recess geometry arranged for maintaining at least one hydrostatic pressure region for preventing the first bearing surface from contacting the stator; and, a fluid pathway between the stator and the impeller.

Vehicle drive device
A vehicle drive device that includes a rotary electric machine that serves as a driving force source for wheels; a first rotation member coupled to a rotor of the rotary electric machine; and a fluid coupling that is disposed on an axial first side, which is one side in an axial direction with respect to the rotary electric machine, and that has a rotation housing.
HYDROKINETIC TORQUE COUPLING DEVICE HAVING TURBINE-PISTON LOCKUP CLUTCH, AND RELATED METHODS
A hydrokinetic torque coupling device includes a casing having opposite sidewalls and an outer wall extending between and connecting the opposite sidewalls, an impeller coaxial aligned with the rotational axis, a piston engagement member extending substantially radially inward from and non-moveable relative to the outer wall of the casing, and a turbine-piston coaxially aligned with and hydrodynamically drivable by the impeller. The turbine-piston includes a turbine-piston shell having a turbine-piston flange with an engagement surface that is movable axially toward and away from an engagement surface of the piston engagement member to position the hydrokinetic torque coupling device into and out of a lockup mode in which the turbine-piston is mechanically locked to and non-rotatable relative to the piston engagement member.
