A stator for use with a torque converter includes an inner annular shell, outer annular core, a plurality of stator blades and pressure-side fluid directing projections. The plurality stator blades are disposed around the inner shell in a spaced apart configuration and radially extend to the outer core. Each stator blade includes an inlet-side edge, an opposed outlet-side edge and opposed pressure-side and suction-side surfaces extending between the inlet-side and outlet-side edges. The pressure-side fluid directing projections outwardly project from the pressure-side surface in spaced relation to each other and each extend between the inlet-side and outlet-side edges. The fluid directing projections are configured to aid in redirecting torque converter fluid returning from a turbine and reducing fluid separation as the fluid interacts with the stator blades and associated fluid directing projections thereby increasing efficiency and performance of the torque converter.

Stator for torque converter

The present disclosure relates to a torque converter, and more particularly, to a torque converter containing a stator having blades with non-linear edges and non-ruled surfaces to increase fluid flow within the torque converter and improve the performance thereof.

A thrust washer for a torque converter, the thrust washer having a curved front surface with a plurality of grooves for increasing fluid flow between the inner diameter and the outer diameter of the thrust washer. This increased fluid flow reduces the buildup of back pressure within the torque converter enabling better operation thereof.

A pendulum absorber assembly for a torque converter including a first spring retainer, a second spring retainer, and a floating flange positioned between the first spring retainer and the second spring retainer. The pendulum absorber assembly also includes a drive plate affixed to the floating flange, a plurality of arcuate springs disposed between the second spring retainer and the drive plate, and a plurality of pendulum weights affixed to the second spring retainer, wherein at least one of the pendulum weights is made of tungsten alloy.

The pendulum absorber assembly also includes a drive plate affixed to the floating flange, a plurality of arcuate springs disposed between the second spring retainer and the drive plate, and a plurality of pendulum weights affixed to the second spring retainer, wherein the pendulum weights are made of tungsten alloy.

A system for controlling the engagement and disengagement of one or more clutches that are adapted to operatively connect an engine and an automatic transmission includes a control device for determining if a negative torque condition exists and for providing an output or signal to decrease the rotational speed of the engine in response to the determination of the existence of the negative torque condition.
