A torque converter including a turbine, a vibration damper, a cover, the cover having blades, and a clutch pack, the blades increasing a fluid flow toward or away from the clutch pack.

Torque converter having blades on the cover

A blade for a stator in a torque converter including a first face, which includes a first step, and a second face located substantially circumferentially opposite the first face. In one embodiment, the first face includes first and second disjointed or misaligned segments, and the first step connects the first and second segments. In another embodiment, the second face includes a second step. In yet another embodiment, the second face includes third and fourth disjointed or misaligned segments, and the second step connects the first and second segments.

Stepped stator blade

The present invention broadly comprises a blade for a torque converter stator including a first blade segment connected to inner and outer circumferential sections of the stator and a second blade segment, separately formed from the first blade segment, and connected to the circumferential sections. In some aspects, the blade segments are: in contact along edges, overlapped, circumferentially misaligned, at least partially folded, stamped, or cast. Configurations of the blade segments can be selected to modify performance characteristics of the stator such as torque ratio, efficiency, and capacity. In some aspects, the blade segments are in a circumferential alignment, and the stator includes an alignment element operatively arranged to control the circumferential alignment, for example, in response to pressure from fluid in the stator upon the blade. In some aspects, the stator includes axial halves, separately formed and fixedly connected and the blade segments are connected to respective halves.

Two-part stator blade

The present invention is one or more torque converter clutch friction pad attached to a friction plate configured to more easily remove heat generated by the friction of a clutch engaging the friction plate. The invention resides in one or more circular grooves set into the friction surface of the friction pad and connected to a plurality of radial grooves. One or more boats or protrusions functionally attached to the clutch pressure plate and/or the torque converter housing fits into the circular groove. When the clutch is engaged, the boats rotate through the circumferential groove pulling oil from the rear radial groove into the circumferential groove and pushing oil into the forward radial groove. The heat generated in the friction plate is transferred to the oil in the circumferential groove and removed from the friction pad when the rotating boat pushes it into the forward radial groove.
