Abstract:
A friction element for a damper disc assembly including a first power input element, a second power input element configured for limited relative rotation with respect to the first power input element, and a power output element elastically coupled to the first power input element for limited relative rotary displacement with respect thereto, said friction element comprising:a body portion formed of a resin material having first and second friction generating surfaces formed on a first side of said body portion, said resin material having a first friction coefficient, only one of said first and second friction generating surfaces having a recess formed therein, said first friction generating surface lying in a first plane, said second friction generating surface lying in a second plane, said first and second planes being generally parallel to one another and spaced apart from one another, said first friction generating surface being sized and configured to contact one of the first power input element and the power output element, said second friction generating surface being sized and configured to contact the other of the first power input element and the power output element;an engaging portion formed integrally with said body portion on a second side of said body portion, said engaging portion extending away from said first and second friction generating surfaces, said engaging portion being sized and configured to be coupled to the second power input element; anda friction adjusting element provided in said recess, said friction adjusting element formed of a material having a second friction coefficient different than said first friction coefficient of said resin material of said body portion so that a frictional force generated by said one of said first and second friction generating surfaces having said recess is modified by said friction adjusting element.
