Patent ID: 7810617

Claim:
Friction element (P) for a disk brake that includes a support plate ( 2 ) and a friction material ( 3 ) fixed on one of the faces of said support plate ( 2 ), said support plate ( 2 ) being substantially in the form of an arc of a circle, and that also includes a projection ( 38 ) extending radially toward the outside of the arc of the circle, a spring element ( 22 ) being fixed to said radial projection ( 38 ), said spring element ( 22 ) being produced from wire wound as turns and provided with a first and with a second arm ( 30 , 32 ) that extend in two opposite directions substantially tangentially to said turns, characterized in that said support plate ( 2 ) includes an orifice ( 40 ) for the fitting of the spring element, in which the wound section is mounted, the first and second arms ( 30 , 32 ) extending on either side of the support plate ( 2 ), and in that the first and second arms ( 30 , 32 ) are of different lengths, the first arm ( 30 ) exerts a first force oriented in a first direction and the second arm ( 32 ) exerts a second force oriented in a second direction, such that the first force is oriented at an acute angle toward the front or toward the rear of the friction element with respect to the second force.
