ASSEMBLED CAMSHAFT FOR INTERNAL EXHAUST GAS RECIRCULATION SYSTEM

摘要

An assembled camshaft (44) comprises a shaft body (101) and a first cam lobe (102). Said first cam lobe (102) is formed integrally on said shaft body (101). An aperture (104) is provided in the outer circumference on the first cam lobe (102). Said aperture (104) includes a wall (107) with a mounting hole (108) therein. A second cam lobe (118) is contacted by a second cam follower (132). Said second cam lobe (118) further includes a cam lobe mounting projection (119). Said second cam lobe (118) is arranged in said aperture (104) and said mounting projection (119) is arranged in said mounting hole (108). A mechanical lock (126; 128) is configured to releasably fix said mounting projection (119) in said mounting hole (108) such that said second cam lobe (118) is replaceable while still being correctly immovably positioned in its operating position.
