Linkage actuating system e.g. for clutch or gear changer has support for actuating member pivoted about fixed point to follow lever movement

摘要

The actuating system, comprising a drive motor (12) and a mechanism to convert the rotation of its output shaft into a reciprocating linear motion of an actuating member (15) connected to the linkage input lever, has a support (24) for the actuating member that is pivoted about a fixed point so it can follow the lever's movement. The actuating member is in the form of a slider (20) with a rack (22) engaging with a pinion (19) driven by the motor, and the pivot can be a ball joint.
