Variable valve lift rocker arm assembly

A variable valve lift rocker arm assembly, comprising:

• a latching axle assembly comprising a first roller latch assembly, a second roller latch assembly, a first latch receiver assembly, and a second latch receiver assembly;
• an outer body comprising:
• one or more valve ends;
• and
• an axle bore comprising one or more sections configured for receiving the first latch receiver assembly and the second latch receiver assembly;
• a first inner body comprising a first inner axle bore configured for receiving at least a portion of the first roller latch assembly;
• a second inner body comprising a second inner axle bore configured for receiving at least a portion of the second roller latch assembly;
• a first roller operatively coupled to one or more of the first roller latch assembly or the first inner body;
• and
• a second roller operatively coupled to one or more of the second roller latch assembly or the second inner body;
• wherein the first roller latch assembly is configured to selectively latch or unlatch with the first latch receiver assembly,
• wherein the second roller latch assembly is configured to selectively latch or unlatch with the second latch receiver assembly,
• wherein each of the first inner body and the second inner body is configured to be selectively rotationally lockable to the outer body independent of the other of the first inner body and the second inner body, and
• wherein the outer body further comprises a plurality of cam ends forming a rotationally coupled integral structure with the one or more valve ends, wherein each of the first inner body and the second inner body is axially enclosed and supported by a respective forked portion of the outer body formed by the plurality of cam ends of the outer body.
