Title:
ACTUATING MECHANISM FOR A SWITCHABLE ROCKER ARM
Document Type and Number:
WIPO Patent Application WO/2023/202802
Kind Code:
A3
Abstract:
An actuation mechanism for selective switching of a valvetrain switching mechanism by a linear actuator mechanism includes an actuator arm having a pin contact surface for engaging an actuator pin of a linear actuator mechanism, a switching arm, and a lever axle pivotally coupling the actuator arm and the switching arm and rotatable about a lever axis, wherein the actuation mechanism is configured to rotate about the lever axis based on a selective extension of the actuator pin, wherein the switching arm is configured to selectively act on the valvetrain switching mechanism based on the rotation of the actuation mechanism; and wherein multiple interface positions on the pin contact surface of the actuator arm are each configured to cooperatively engage with the actuator pin at an orthogonal angle to the axis of linear motion of the actuator pin.
