Abstract:
1. A one-way clutch, comprising: a first annular element; a second annular element arranged to lockingly engage with the first element for relative rotation of the second element, with respect to the first annular element, in a first rotational direction; a third annular element at least partly rotatable about the axis and axially disposed between the first and second elements; and, a fourth annular element at least partly rotatable about a longitudinal axis for the one-way clutch and including a radially disposed body and an axial protrusion extending from the body and connected to the third element, wherein: the axial protrusion forms a portion of a space arranged to at least partially enclose fluid to dampen energy associated with the locking engagement of the first and second annular elements; the first or second element is axially disposed between the third and fourth elements; the axial protrusion includes a first portion, bent over the third element and facing the first or second element, to rotationally connect the third and fourth elements; the first or second element includes a protrusion and at least one slot proximate a circumferential end of the protrusion; and, during rotation of the second element in the first rotational direction at least one second portion of the axial protrusion is at least partially disposed in the at least one slot.
