Abstract
A friction plate for a clutch includes a face and a first friction material disposed on the face. The first friction material has a first composition including a first filler material at a first weight concentration of a total weight of the first friction material. A second friction material is disposed on the face and has a second composition that is different than the first composition and including a second filler material at a second weight concentration of a total weight of the second friction material. The second weight concentration is higher than the first weight concentration.
Claims20
A friction plate for a clutch comprising:
- a face;
- a first friction material disposed on the face and having a first composition including a first filler material at a first weight concentration of a total weight of the first friction material;
- and
- a second friction material disposed on the face and having a second composition that is different than the first composition and including a second filler material at a second weight concentration of a total weight of the second friction material that is higher than the first weight concentration.
A method of manufacturing a friction plate comprising:
- applying a first friction material to a face of a friction plate, the first friction material having a first composition including a first filler material at a first weight concentration of a total weight of the first friction material;
- and
- applying a second friction material to the face, the second friction material having a second composition that is different than the first composition and including a second filler material at a second weight concentration of a total weight of the second friction material that is higher than the first weight concentration.
A friction plate for a clutch comprising:
- a face;
- patches of friction material disposed on the face and having a first composition including a first filler material, a first fiber material, and a first binder forming a total weight of the friction material, wherein the first filler material is at a first weight concentration of less than 30 percent by weight of the total weight of the friction material;
- and
- at least one wiper patch disposed on the face and having a second composition that is different than the first composition and including a second filler material, a second fiber material, and a second binder forming a total weight of the wiper patch, wherein the second filler material is at a second weight concentration that is greater than 32 percent of the total weight of the wiper patch, and wherein the second binder includes a silane coupling agent configured to, in combination with the second composition, soften the wiper patch compared to the friction material such that a portion of the second filler of the wiper patch is released during operation of the friction plate to scrub deposits of decomposed transmission fluid from the friction material to inhibit surface plugging.
