ROTATION SPEED SENSING UNIT FOR AUTOMATIC TRANSMISSION

摘要

PURPOSE: A rotation speed sensing unit for automatic transmission is provided to reduce manufacturing costs by forming a sensing dog with an extension part of an output shaft. CONSTITUTION: A connection unit(7) is connected between an output shaft(1) and a rotating member(5). A sensing unit is combined with the connection unit as one body. The connection unit comprises an extension part(11) expanded to a revolution sensor(9). The extension unit is formed with the sensing unit(13) sensing the speed of the revolution sensor. An output shaft is rotated while being connected to a rotating member of the planetary gear set(3). The output shaft transfers the output torque to a differential motion device.
