Internal combustion engine valve gear drive device for automobile field, has two shafts connected and inter-connected by respective homo-kinematic connection and with cams actuating inlet and outlet valves respectively

摘要

The device has two shafts (3) with respective cams (2) actuating two inlet valves (1), and two shafts (7) with respective cams (6) actuating two outlet valves (5). The shafts (3, 7) are connected by respective homo-kinematic connections (10, 12) and inter-connected by a homo-kinematic connection (14). The connections (10, 12) comprise tapered pinions (11, 13) that mesh with two adjacent ends of the shafts, respectively. A tapered roller bearing applies an axial force to the ends of the shafts for maintaining the pinions (11, 13, 15, 16) in meshing.
