Rotating part`s e.g. crankshaft, angular position determining disk e.g. toothed disk, for internal combustion engine, has radial edges forming rising edges for sensor during disk rotations relative to normal and reverse rotation directions

摘要

The disk has slots (R1-Rn) uniformly distributed on the periphery of the disk and formed of teeth (D1-Dn) and holes (C1-Cn) delimited by radial edges (F1-Fn, F`1-F`n). The edges (F1-Fn) form one set of equidistant angular markers separated by an interval (T1). The edges (F`1-F`n) form another set of non-equidistant angular markers separated by intervals (T`1-T`3). The radial edges (F1-Fn, F`1-F`n) form rising edges for a magnetic sensor e.g. Hall effect sensor, during disk rotations corresponding to normal and reverse rotation directions of an internal combustion engine, respectively.
