  • Publication number: 20130312689
    Abstract: A switching rocker arm having an outer arm having a first end, a second end, a first and second outer side arm having slider pads that ride on a second cam is disclosed. The switching rocker arm also has an inner arm disposed between the first and second outer side arms. The inner arm has a first end, a second end and a bearing disposed between the first and second end adapted to ride along a first cam. The inner arm is pivotably secured adjacent its first end to the outer arm adjacent its first end. At least one arm has an over-travel limiter structure limits pivoting motion of the first arm relative to the second arm. The switching rocker arm also exhibits decreased lash as the bearing wears, and increased lash as the latch and slider pads wear.

  • Publication number: 20110226209
    Abstract: A rocker arm for engaging a cam is disclosed. An outer arm and inner arm are configured to transfer motion to a valve of an internal combustion engine. A latching mechanism includes a latch, sleeve and orientation member. The sleeve engages the latch and a bore in the inner arm, and also provides an opening for an orientation member used in providing the correct orientation for the latch with respect to the sleeve and the inner arm. The sleeve, latch and inner arm have reference marks used to determine the optimal orientation for the latch.

  • Publication number: 20050165588
    Abstract: Extreme event performance evaluation using real-time hysteresis monitoring. A structure is monitored using one or more sensors. One or more inter-story Hysteresis Loops for the structure are generated in real-time using data from the sensors, thus enabling rapid decision making regarding the structure's condition.
