摘要： A rocker arm includes an outer arm defining a lock pin bore which is centered about a lock pin bore axis and an inner arm which selectively pivots relative to the outer arm about a pivot axis which is parallel to the lock pin bore axis. The inner arm includes a protrusion which defines an inner arm stop surface which is planar. A lock pin is disposed within the lock pin bore, the lock pin having a lock pin slot extending thereinto and also having a lock pin stop surface which is planar. The lock pin is displaced within the lock pin bore between a coupled position in which the lock pin stop surface is aligned with the inner arm stop surface and a decoupled position in which the lock pin slot is aligned with the protrusion.

摘要： A rocker arm includes an outer arm and an inner arm which selectively pivots relative to the outer arm. The rocker arm also includes a lock pin which is displaced along a lock pin axis between a coupled position and a decoupled position. The rocker arm also includes a linkage and a linkage guide which guides the linkage along a linkage axis. One surface of the linkage engages an actuator while another surface of the linkage engages the lock pin such that the linkage translates motion from the actuator to motion of the lock pin.

摘要： A rocker arm includes an outer arm having a first wall and a second wall and an inner arm which selectively pivots relative to the outer arm about a pivot shaft axis of a pivot shaft based on positioning of a lock pin. A lost motion spring includes an outer arm tang grounded to the outer arm and an inner arm tang grounded to the inner arm. A roller shaft is supported by the inner arm and extends toward the first wall. The roller shaft carries a roller which follows a camshaft. A roller retainer is carried by the roller shaft and is located between the roller and the first wall and includes a surface with which the inner arm tang is engaged to ground the lost motion spring to the inner arm, a roller shaft aperture containing the roller shaft, and a pivot shaft aperture containing the pivot shaft.
