TORQUE CONVERTER

WIPO Patent Application WO/2012/023240

A1

Disclosed is a torque converter (1) which comprises: a casing (10) coupled to an output shaft of an engine; a torus (T) defined by a pump (20), a turbine (30) and a stator (40) each disposed within the casing (10); a lockup clutch (60) adapted to directly couple the turbine (30) and the casing (10); and a lockup damper (70) adapted to absorb shock during engagement of the lockup clutch (60). The turbine (30) has an outer peripheral portion (31a) bulging toward the engine to define a part of the torus (T), an inner peripheral portion (31c) located on the side of the engine with respect to a one-way clutch (50) supporting the stator (40), and an intermediate portion (31b) formed to be concaved toward a side opposite to the engine, in a radial position between the outer peripheral portion (31a) and the inner peripheral portion (31c). A part (75) of the lockup damper (70) is disposed on the side of the engine with respect to the intermediate portion (31b) and in a position axially overlapping with the torus (T). This makes it possible to allow a torque converter to be axially downsized.
