Sealing device for automobile rotary part, such as crank-shaft

摘要

The sealing device has a sealing system (1), a rotary part and a device (2) providing a path for the radial part(s) of the sealing system, incorporating a receiver for rotation data relating to the rotary part. The sealing device may be used for the end of the engine crankshaft, with an integrated sealing system employing sealing components (20,30,40), vulcanised to the component (10) within the engine block surrounding the crankshaft. The receiver incorporated in the device providing a path for the radial sealing elements is used for providing crankshaft rotation signals.
