A method for manufacturing a joined member and a joined member manufacturing apparatus which can manufacture a joined member with a joint portion having an appropriate hardness. A method for manufacturing a joined member C by joining a first member D formed of a metal material having a possibility of undergoing quenching and a second member E formed of a metal material, the method includes a contact-placing step Sof placing the first and second members D and E with joint target portions of the first and second members D and E respectively being in contact with each other; a joining step Sof joining the first and second members D and E by passing a pulsed welding electric current Afor joining through the joint target portions J of the first and second members D and E; a first tempering step Sof tempering a joint portion F, where the first and second members D and E are joined, by passing a first tempering electric current Athrough the joint portion F; and a second tempering step Sof tempering the joint portion F by passing a second tempering electric current Asmaller than the first tempering electric current Athrough the joint portion F.

Method for manufacturing joined member and joined member manufacturing apparatus

A differential with a differential action limiting mechanism includes a differential mechanism D for distributing the drive force of an internal combustion engine inputted into a differential caseto a left-hand axle shaftand a half shaftwhich continuously connects to a right-hand axle shaft for output therefrom and friction clutchesL,R for limiting differential rotations of the left-hand axle shaftand the half shaftrelative to the differential case. An actuator A for generating an engagement force for bringing the friction clutchesL,R into engagement is provided outside a housingfor accommodating therein the differential case, whereby an engagement force generated by the actuator A is transmitted to the friction clutchesL,R via the half shaft

Limited slip differential

The differential includes a differential casing configured to be rotatably driven by a motor under a driving force. The differential includes a differential mechanism which includes a pair of first and second side-gears for distributing a torque of the differential casing to first and second output shafts. The differential includes a frictional clutch for interconnecting the first and second output shafts. The frictional clutch includes first and second power-transmitting members connected to first and second output shafts respectively and first and second clutch plates. The first and second clutch plates are connected to the first and second power-transmitting members respectively. The differential includes an actuator for operating the frictional clutch. One output shaft of the first and second output shafts is axially displacable by the actuator under an engagement force to engage the frictional clutch.

Differential

Two sensors are provided on a clutch core. Sensor coils are driven at a high frequency by a high-frequency driving circuit. As the sensors sense a magnetic flux of a magnetic circuit including the clutch core and an armature, the impedance of the sensor coils changes. In accordance with the outputs from the sensor coils at this point, an impedance detecting circuit detects the impedance of the sensor coils. Then, an impedance combining circuit combines the impedance of the sensor coils. On the basis of the combined impedance, a current control circuit controls a current supplied to an exciting coil. Thus, the attracting force of the armature to the core excited by the exciting coil is controlled.
