Actuator device for friction clutch adjustment and movement
The patent US12044274B2 describes an actuator device specifically designed for friction clutches. The device features a push lever arm that applies force to the friction clutch, equipped with first and second slots for accommodating pins from a bearing and a drive unit. The push ring, which contacts the friction clutch, is journaled by the bearing, allowing it to rotate about a designated axis. Notably, the push ring and bearing are pivotally arranged within the second slots of the push lever arm, enabling them to pivot and adjust their position relative to the push lever arm. This design allows for enhanced flexibility in the actuator's operation, as the push ring pivot axis can be adjusted in a direction that is substantially perpendicular to both the push lever arm movement direction and the push ring pivot axis.
Further claims detail the structural relationships between various components of the actuator device. The rotation axis of the push ring is positioned substantially perpendicular to the push ring pivot axis, and the push lever arm can pivot relative to the drive unit about a drive unit pivot axis. The drive unit, which includes a motor and a linear actuator mechanism, is designed to facilitate the movement of the push lever arm. Additionally, the push lever arm can be pivotally connected to a fixed point, allowing for further adjustments in the positioning of the push ring pivot axis. The claims also extend to the integration of the actuator device within a friction clutch and a transmission system, highlighting its potential applications in automotive engineering.
