Torque converter assembly centering features

摘要

An assembly for centering components with respect to an axis of rotation of a torque converter during installation of the torque converter on a transmission input shaft, the assembly including a cover for receiving a torsional input, a piston housed within the cover, a damper housed within the cover, the damper including a damper cover plate and a damper flange, wherein the piston, the damper cover plate, or the damper flange includes an extension, wherein the extension is operatively arranged for providing a centering function of the piston, the damper cover plate, or the damper flange by limiting a maximum radial distance a second axis of the piston, the damper cover plate, or the damper flange can become misaligned from the axis of rotation of the torque converter.

主权项

1. A torque converter, comprising:
a cover for receiving torsional input; an impeller non-rotatably connected to the cover; a turbine; a damper including:
a first cover plate non-rotatably connected to the turbine;a second cover plate:
non-rotatably connected to the first cover plate; and,including an end furthest from an axis for the torque converter;a flange arranged to non-rotatably connect to an input shaft via a splined connection between the flange and the input shaft; and,a plurality of springs engaged with the first and second cover plates and the flange and arranged to transfer torque between the first and second cover plates and the flange; a lock-up clutch including:
a clutch plate including a portion:
parallel to the axis of rotation; and,non-rotatably connected to the first cover plate; and,a piston, separate from the clutch plate:
arranged to displace in the axial direction to non-rotatably connect the cover and the clutch plate; and,including a portion located radially between the end of the second cover plate and the portion of the clutch plate; and, a gap, in a radial direction orthogonal to the axis, between the end of the second cover plate and the portion of the piston, wherein no component of the torque converter is located in the gap.
