Ferromagnetic object for internal combustion engine, has hollow part with length higher than length of another hollow part, where one hollow part has tooth including lower dimension with respect to teeth between which tooth is disposed

摘要

#CMT# #/CMT# The object (4) has teeth (10) projected from a circular ring (8), such that the succession of solid parts corresponding to the teeth and hollow parts (16) corresponding to free space between the teeth is provided at the periphery of the ring, where the hollow parts have different angular length. The object is in a form of tooth wheel. One of the hollow parts has the angular length higher than the angular length of other hollow part. Each hollow part has a tooth (23) having a lower dimension with respect to the teeth (10) between which the tooth is disposed. #CMT# : #/CMT# An independent claim is also included for a device for determining an angle position of camshaft. #CMT#USE : #/CMT# Ferromagnetic object for a determination device that determines an angle position of a brake camshaft of an internal combustion engine (claimed) in an automobile industry. #CMT#ADVANTAGE : #/CMT# The ferromagnetic object has lesser diameter while providing better sensibility to a sensor. The configuration of the ferromagnetic object reduces the instability of the operation of an integrated circuit of the sensor. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of a ferromagnetic object. 4 : Ferromagnetic object 8 : Circular ring 10, 23 : Teeth 16 : Hollow parts 30 : External peripheral surface.
