Internal-combustion engine, has housing part provided with recess in which drive wheel is guided in sections such that wheel cooperates with front surface areas of front surfaces and forms axial bearing for shaft

摘要

The engine has a cam shaft system (1) provided with a cam shaft (2) for controlling gas shuttle valves. A drive wheel (4) is torque-proofly and dislocation-resistantly arranged on the cam shaft. A housing part (6) includes an housing-internal recess (8) in which the drive wheel is axially guided in sections such that the drive wheel cooperates with front surface areas (4a') of its two lateral opposite drive wheel front surfaces (4a) with respective side wall areas (8a') of a side wall (8a) of the recess and forms an axial bearing for the shaft.
