Engine starter for motor vehicle, has clutch allowing armature shaft to rotate in normal direction and preventing reverse rotation of armature shaft when output shaft applies reverse torque from motor rotating in reverse direction

摘要

The starter has an electric motor generating a torque in an armature shaft (13), and an output shaft (5) coupled to the shaft (13). A pinion (7) is disposed on the shaft (5). A clutch allows the shaft (13) to rotate in a normal direction to actuate the motor in the normal direction and prevents a reverse rotation of the shaft (13) when the output shaft applies a reverse torque from the motor rotating in the reverse direction.
