Crankshaft torque transmission pulley for internal combustion engine, has shock absorber unit placed between hub and external rim, and coder unit arranged in axial extension of absorber unit to detect pulleys rotation parameters

摘要

The pulley has a hub (4), an external rim (5), and an intermediate shock absorber unit (6) disposed radially between the hub and the rim. A coder unit (15) cooperating with a sensor is arranged in an axial extension of the intermediary shock absorber unit. The coder unit disposed to an interior of a space between the external rim and the hub detects rotation parameters of the pulley. An independent claim is also included for an internal combustion engine including a crankshaft rotation parameter detecting device with a pulley.
