Electronic throttle system controlling motor vehicle IC engine air intake - has electronically controlled throttle adjusting element with throttle valve and motor for producing torque for operating throttle valve and gear train

摘要

The control system includes a motor controller (155) for controlling rotation of the motor (105) and a Host system (114) for carrying out a general control of a throttle system. A gear train (103) transmits the torque produced by the motor. A magnetic coupling (110) is provided for connecting and separating the transmission of the torque. The motor and the throttle valve are arranged in a U-shaped formation for a connection together one below the other, across the gear train. The coupling is arranged on the same side as the motor, in order to be axially aligned with it.
