Hypocycloidal release device for motor vehicle clutch, has contours formed along lines with radii with center point, respectively, where one radius is equal to twice of another radius and lines are arranged within pivot plane of lever

摘要

The device (10a) has a clutch lever (22) pivotable around a bearing area (24) within a pivot plane. The lever has a force absorbing area (26) absorbing actuation force of an actuator (28), and a force transmission area (44) transmitting the force to a releaser (18). The area has bearing elements (32, 36) with engagement contours (32a, 36a). The contours are formed along circular lines (38, 40) with radii (R, r) with a center point on a release axis (A), respectively, where one radius (R) is equal to twice of the other radius (r). The circular lines are arranged within the plane of the lever.
