Abstract:
1. An overrunning clutch clamping body for use in an overrunning clutch comprising a first contact surface and a second contact surface for contacting respective clamping raceways, each of these contact surfaces comprising a curvature deviating from zero in each direction, wherein each of the first and second contact surfaces is configured symmetrically both to a first plane (E 1 ) extending normal to an axis of rotation of the overrunning clutch and to a second plane (E 2 ) that is perpendicular to the first plane (E 1 ), and a shape of the first contact surface corresponds to a shape of the second contact surface wherein a line of intersection between the contact surface and the first plane (E 1 ) describes a logarithmic spiral and each of different sections of the line of intersection situated on a side of the second plane (E 2 ) describes a logarithmic spiral whose center point (M 1 , M 2 ) is situated at a distance from the second plane (E 2 ).
