Definitions
- the invention relates to improvements to a device for the Fiüsstechniksstrom in a torque converter.
- the invention relates to a thrust washer which permits fluid flow between a torque converter-associated transmission shaft and components around the hub of the torque converter while minimizing interruptions in the surface of the disc.
- FIG. 13 is a plan view of a prior art thrust washer 300.
- a thrust washer for example the thrust washer 300, is placed between the hub and the lid.
- fluid circuits for cooling fluids such as oil, must be created in the torque converter.
- the thrust washer is partially in the way of the required fluid circuits, so care must be taken that fluid can pass between the inner and outer circumferential surfaces 302 and 304 of the disc 300, respectively.
- slits 306 are known to be provided in the surface 308 of the disc 300. Usually, this surface 308 comes into contact with the above-mentioned cover.
- the slots 306 create discontinuities in the surface 308 which increase wear of the thrust washer. Increased wear leads to shorter service life of the thrust washer, which in turn can affect the service life and / or the maintenance intervals required for the torque converter. Increased wear can also increase the component cost because the disc needs to be made from more expensive, wear-resistant materials. Thus, there has long been a need for a thrust washer that allows sufficient fluid flow rate while maximizing the contact surface area of the disc.
