摘要
PURPOSE: A vehicle speed sensor is provided to intensify the durability of the device with compared with a conventional method of a driving gear and a driven gear by connecting a magnetic field unit with a case directly.;CONSTITUTION: In a vehicle speed sensor, a speed detection system includes a magnetic field generation unit(100) and a speed perception unit. The magnetic field generation unit is formed as a ring type while being composed of a permanent magnet. Only the S polity of each magnet of the magnetic field generation unit is toward the speed detection system. A circuit part(220) is formed inside the speed detection system and is located at one end of it, and a hall sensor(210) is mounted in the circuit part.;COPYRIGHT KIPO 2010
