Signal transmitter wheel for acquisition of rotational position of shaft e.g. cam shaft, of combustion engine in motor car, has two parts connected and fixed with one another by connector, where wheel is manufactured by sintering process

摘要

The wheel (1) has two parts (5, 6) connected and fixed with one another by a connector (7) i.e. dowel, and made by rupture separation, where the wheel is manufactured by sintering process. A hole is formed as a through-hole, and another hole is formed as a blind bore and comprises an internal thread that is complementary to an external thread of a screw (7'), where the two holes are oppositely formed. The through hole has large diameter as compared to the blind bore. An independent claim is also included for a method for manufacturing a signal transmitter wheel.
