The present disclosure sets forth a one-way clutch. The one-way clutch can function with one or no races as opposed to conventional prior art one-way clutches. In so doing, the overall size and weight requirements of the one-way clutch are drastically reduced, which in turn drastically reduces the overall size and weight requirements of the transmission and vehicle employing the transmission as well. The present disclosure also provides a one-way clutch having an outer race provided by axially spaced plates. An inner race is rotatably mounted with respect to one of the plates and the inner race has a ratchet surface. Ratchet pawls are pivotably mounted with respect to the plates and have unidirectional engagement with the ratchet surface of the inner race. In addition to reducing material and labor production costs, such lessened size and weight penalties translate into higher transmission efficiency and better vehicle fuel economy.

A torque convertor stator includes an annular bearing support, a plurality of stator blades, and a web extending radially between the annular bearing support and the plurality of stator blades. The annular bearing support, the plurality of stator blades, and the web are formed from a single continuous piece of amorphous metal.

A torque converter includes an impeller and a cover non-rotatably fixed to the impeller. The cover has opposing inner and outer surfaces and a through hole extending from the inner surface to the outer surface. A lug has a collar adjacent the outer surface, a shank extending from a first side of the collar, and a stem extending from a second side of the collar. The stem is disposed in the hole and attached to the cover by a connection.

A side plate utilized in a torque converter, comprising a first annular surface, a second annular surface opposite the first annular surface, an outer race defining an outer peripheral of the first and second annular surface, an inner race defining an inner peripheral of the first and second annular surface, and a neck extending axially away from the second annular surface and located along the inner race.

A stator assembly of a torque converter includes a stator having circumferentially arranged blades, an inner ring, and projections circumferentially arranged around the inner ring and extending radially inward therefrom. An annular plate is circumscribed by the inner ring and has a plurality of attachment portions circumferentially arranged around an outer surface of the plate. Each of the attachment portions engages with an associated one of the projections and has a pair of spaced anti-rotation tabs that define a receptacle. The receptacle receives the associated one of the projections to prevent relative rotation between the stator and the plate.

A transmission includes: a torque converter; a transmission input shaft; a seal member sandwiched between the hollow shaft and the transmission input shaft; and a bush, the transmission input shaft including a large diameter portion abutted on the seal member, and a small diameter portion which is positioned on the tip end side of the large diameter portion, and which has a diameter smaller than a diameter of the large diameter portion, the seal member having a diameter larger than a diameter of the bush, and the small diameter portion having an axial length set to be longer than a length from an insertion inlet of the transmission input shaft of the bush to the seal member.

A driving apparatus for a vehicle is disclosed. The driving apparatus is used for transmitting drive force to a first output shaft. The driving apparatus includes a housing, a motor, a torque converter and an oil reservoir unit. The housing includes a first oil chamber and a second oil chamber. The motor is disposed in the first oil chamber. The torque converter forms the second oil chamber and transmits drive force of the motor to the first output shaft. The oil reservoir unit is disposed radially inward of the torque converter. The torque converter guides hydraulic oil from the oil reservoir unit to the second oil chamber by centrifugal force.

A powertrain system includes a flex plate, a transmission input shaft, a torque coupling, a one-way clutch, and a damper assembly. The flex plate is configured to be connected to a crankshaft of an engine. The torque coupling connects the transmission input shaft to the flex plate while allowing slip between the transmission input shaft and the flex plate. The one-way clutch is configured to couple the flex plate to the torque coupling. The damper assembly couples the flex plate to the one-way clutch and is configured to inhibit vibration transmission from the flex plate to the one-way clutch.

A torque converter includes a turbine including a plurality of turbine blades and an inner radial extension radially inward from the turbine blades. The torque converter also includes a stator including a plurality of stator blades and a stator body supporting the stator blades. At least one of the inner radial extension and the stator body is provided with a stator retaining assembly to limit radial movement of the stator with respect to the turbine.

A torque converter (10) translates torque between an internal combustion engine and an automatic transmission. The torque converter (10) includes a rotatable torque input member (20) adapted to be operatively coupled to a crankshaft of the internal combustion engine, and an impeller assembly (12) operatively coupled to rotate with the torque input member (20). The torque converter (10) further includes a turbine assembly (14) and a one-way clutch assembly (62). The turbine assembly (14) is fluidly connected in driven relationship with the impeller assembly (12) and adapted to be coupled to a rotatable transmission input shaft (56). The one-way clutch assembly (62) is disposed radially between the turbine assembly (14) and the transmission input shaft (56).
