ONE-WAY TURBINE WEDGE CLUTCH

摘要

A torque converter, including: a cover; a pump shell non-rotatably connected to the cover; a turbine shell; and a one-way clutch including: an outer race non-rotatably connected to the turbine shell and including a groove; an output hub including a first outer surface with first ramps; and at least one wedge plate including a second inner surface with second ramps engaged with the first ramps and a second outer surface disposed within the groove. For rotation of the outer race with respect to the output hub in a first direction, the outer race is rotatable with respect to the at least one wedge plate and the output hub. For rotation of the outer race with respect to the hub in a second direction, opposite the first direction, the at least one wedge plate is arranged to non-rotatably connect the outer race and the hub.

1. A torque converter, comprising:
a cover; a pump shell non-rotatably connected to the cover; a turbine including a turbine shell; and, a one-way clutch including:
an outer race non-rotatably connected to the turbine shell and including a first inner circumferential surface with a circumferentially continuous groove;an output hub arranged to non-rotatably engage an input shaft for a transmission, and including a first outer circumferential surface with a first plurality of ramps; and,at least one wedge plate including:
a second inner circumferential surface with a second plurality of ramps engaged with the first plurality of ramps; and,a second outer circumferential surface at least partially disposed within the groove, wherein: for relative rotation of the outer race with respect to the output hub in a first rotational direction, the outer race is rotatable with respect to the at least one wedge plate and the output hub; and, for relative rotation of the outer race with respect to the output hub in a second rotational direction, opposite the first rotational direction, the at least one wedge plate is arranged to non-rotatably connect the outer race and the output hub.
