Abstract: A lock-up device for a torque converter transmits a torque from a front cover to a transmission-side member through a turbine. The lock-up device includes a clutch portion and a damper portion. The clutch portion includes a clutch plate and transmits the torque from the front cover toward the turbine. The damper portion includes an elastic member, a holding member and an output-side member. The elastic member attenuates a fluctuation in the torque. The holding member holds the elastic member and is provided with an engaging part integrated therewith. The engaging part is engaged with the clutch plate. The output-side member is rotatable relatively to the holding member within a range of a predetermined angle. The output-side member transmits the torque toward the turbine when the torque is transmitted to the elastic member through the holding member.

Abstract: An oil-flooded single-plate or multi-plate lockup clutch is provided in a torque transfer device. The torque transfer device may, for example, be a converter, a dual clutch, a starting clutch, a manual shifter, or power shifting clutch, having a piston to engage the clutch and a damper. In accordance with the present disclosure, the piston together with a housing of the torque transfer device forms a closed pressure chamber when the clutch is engaged and at least one oil flow opening is provided in the piston in an area outside of the pressure chamber. The torque transfer device preferably has a damper and the piston of the clutch forms a part of the damper and may be designed as a retainer for springs of the damper.

Abstract: A lock-up device includes a clutch portion, a piston, a sleeve and an oil chamber plate. The clutch portion is disposed between the front cover and a turbine. The piston is movable in an axial direction. The piston turns the clutch portion into a torque transmission state. The sleeve is fixed to a front cover and includes an outer peripheral surface and a protrusion. The outer peripheral surface supports an inner peripheral surface of the piston such that the piston is movable in the axial direction. The protrusion has an annular shape and protrudes radially outward from the outer peripheral surface. The oil chamber plate has a disc shape and is joined to a piston-side lateral surface of the protrusion of the sleeve. The oil chamber plate defines an oil chamber together with the piston therebetween. The oil chamber is supplied a hydraulic oil for activating the piston.

Abstract: A lock-up device for a torque converter is configured to transmit a torque from a front cover to a transmission-side member through a turbine. The lock-up device includes a clutch portion, a piston and an elastic member. The clutch portion is disposed between the front cover and the turbine, and includes a clutch plate. The piston is movable in an axial direction. The piston includes a pressing surface for pressing the clutch plate. The piston turns the clutch portion into a torque transmission state. The elastic member is disposed on a same side as the pressing surface of the piston. The elastic member is begins to elastically deform before the pressing surface contacts the clutch plate in conjunction with movement of the piston toward the clutch portion.

Abstract: Lock-up clutch engagement hydraulic pressure learning control can be precisely performed by starting lock-up clutch engagement control and executing the lock-up clutch engagement hydraulic pressure learning control after execution of shift control is completed, in a case where the lock-up clutch engagement control is limited in a shift stage before execution of the shift control, when the shift control is executed in a state where a multi-disc lock-up clutch is released. Meanwhile, a decrease in fuel efficiency performance and a direct steering feeling is minimized by starting the lock-up clutch engagement control during shift control in a case where the lock-up clutch engagement control is not limited.
