Abstract: An oil-cooled motor/generator for an automotive powertrain located outside of the transmission is provided, such as a BAS motor/generator. The motor/generator may have a stator, a rotor circumscribed by the stator, and a motor shaft on which the rotor is mounted for rotation. A housing assembly may surround the stator and the rotor, with a bearing positioned between the housing assembly and the motor shaft. A flow control member may at least partially circumscribe the rotor axially adjacent the stator. A bearing retainer may be positioned axially adjacent the bearing. A rotor end ring may be axially adjacent the rotor. The housing assembly may have an inlet configured to receive cooling oil. The housing assembly, the flow control member, the bearing retainer and the rotor end ring may be configured to distribute the cooling oil from the inlet to cool the stator, the rotor and the bearing.

Abstract: A transmission assembly includes a clutch housing, a gear arrangement disposed within the clutch housing, and a fixed component. A brake having a housing and a hub is also included. The housing is coupled to the fixed component and the hub is coupled to the gear arrangement. The brake is disposed external to the clutch housing and cooperates with the gear arrangement to provide at least one forward or reverse gear ratio.

Abstract: The pinion gear assembly thus includes a first and a second pinion gear arranged with generally parallel axes of rotation. A first and a second washer, referred to herein as stationary washers, are provided. Each of the washers has two openings spaced to generally align with two predetermined, spaced mounting locations on the planet carrier member. The first and the second washers are positioned on opposing sides of the first and second pinion gears, with the axes of rotation of the first and second pinion gears generally centered at the respective spaced openings of the washers. Because the stationary washer spans the two pinion gears, which are secured to the carrier member, the stationary member is operatively connected at two locations to the carrier member, eliminating the need for anti-rotation features and corresponding carrier features.

Abstract: A modular transmission assembly includes a transmission housing that defines a hollow interior. The transmission housing extends along a central axis between a front end and a rear end. A rear motor module is disposed in, and is operatively connected to, the transmission housing. An inner module is disposed in, and is operatively connected to, the transmission housing. A main shaft is disposed along the central axis such that each of the rear and inner modules radially surround the main shaft. A front motor is disposed in the transmission housing and radially surrounds the main shaft. The inner module is axially disposed between the rear motor module and the front motor. An input module is connected to the front end of the transmission housing. The front motor is axially disposed between the inner module and the input module.

Abstract: A planet carrier assembly has a plurality of pinion gears rotatably mounted on pinion pins, each pin having a slot formed thereon. A locator ring is assembled onto the pinion pins and rotated in a manner such that the locator ring engages the slots in the pinion pins and a plurality of tabs and protuberances engage complementary components formed on a housing member of the planet carrier assembly. The locator ring ensures both axial and rotational positioning of the pinion pins within the planet carrier housing.

Abstract: A low profile transmission filter system is provided that is connectable between a transmission casing and an oil pan. The filter system includes a filter housing with an open bottom and a flange there around and forming a tubular opening opposite the open bottom. A seal member is secured along the flange and has two ends spaced from one another to define a gap there between. The seal member compresses against an inner surface of the oil pan when the oil pan is connected to the transmission casing to define a filter cavity within the filter housing with an inlet at the gap.

Abstract: A shaft assembly includes a fluid transfer insert located within a bore of a shaft. The fluid transfer insert seals to the shaft and includes at least one fluid channel that communicates between a plurality of fluid ports located in the shaft. The fluid channel is defined by an outer surface of the fluid transfer insert.

Abstract: A rotating electric machine apparatus includes at least one end plate associated with an inner assembly unit that operates to prevent contact between the inner assembly unit and an outer assembly unit. The end plate is peripherally sized to allow the slidable assembly of the inner assembly unit into the outer assembly unit while preventing undesirable contact of the inner assembly unit with the outer assembly unit.

Abstract: A transmission casing adapter ring is provided that enables a transmission having a common outer casing to be operatively connected to an engine, thus enabling different engines to be used with the common transmission outer casing simply by changing the adapter ring. The adapter ring allows a novel method of assembling a powertrain that permits assembly of the transmission with a generic (i.e., common) type of casing prior to a determination of the engine type or types to be used with the transmission. The adapter ring is aluminum, the transmission case is magnesium, and the engine is cast iron.

Abstract: A transmission pump adapter ring is provided that enables a transmission pump assembly to be operatively connected to an engine, thus enabling a common transmission pump assembly to be used in a given type or types of transmissions while enabling different engines to be used with the transmission simply by changing the adapter ring. The adapter ring allows a novel method of assembling a powertrain that permits assembly of the transmission with a generic (i.e., common) type of pump assembly prior to a determination of the engine type or types to be used with the transmission.

Abstract: The present invention provides a transmission assembly having a clutch housing, a gear arrangement disposed within the clutch housing, and a fixed component coupled to the clutch housing. A brake having a housing and a hub is also included. The housing is coupled to the fixed component and the hub is coupled to the gear arrangement. The brake is disposed external to the clutch housing and cooperates with the gear arrangement to provide at least one forward or reverse gear ratio.

Abstract: A hybrid transmission including two electric motors and a plurality of planetary gear sets operatively connectable to the motors and to an engine is provided. Novel motor features are provided including structure adapted to improve reliability and to facilitate assembly. More precisely, a method is provided for locating and installing the components of a motor, including a rotor and a stator, within a covered housing to form a motor module. A plurality of rotor bearings and a position/speed sensor are also preferably added to the motor module. After the motor module is assembled, the motor may be tested and thereafter the motor module can be installed into a hybrid transmission as a single component utilizing conventional transmission assembly methods.

Abstract: The present invention is directed to a sealing cap assembly (10) of the type that is particularly adapted for use in closing and venting the access aperture (60) of a transmission housing (58). The embodiment of the sealing cap assembly (10) disclosed, has a body portion (15) and a cap portion (20). The body portion (15) has a radially outermost extent with at least one thread path (51 and/or 52) extending along, and being recessed inwardly with respect to, the outermost extent of the body portion (15). At least one hollow cubicle (46, 47, 48 or 49) is provided interiorly of the body portion (15). Port means (73 and/or 74) penetrate the body portion (15) in order to provide communication between at least one the thread paths (51 and/or 52) and the hollow cubicle (46, 47, 48 or 49).

Abstract: A gear range indicator for use with automatic transmission which is remote from the shift mechanism, yet requires little or no adjustment to be made to the mechanical linkage to compensate for variations in the position of the display relative to the shift mechanism. The gear range indicator uses light conducting columns to illuminate symbols corresponding to the gear range selected. An opague indicator control strip with an aperture blocks light from reaching the columns except for that light passing through the aperture. The aperture is aligned with the column corresponding to the gear range selected.
