Driving torque transmission control apparatus used in an automotive vehicle

摘要

A driving torque transmission control apparatus that is rotatably supported onto a vehicle body through a support bearing supported by a bearing holding device including an absorber and a bearing holding member, and that is serially disposed between driving force transmission axles. The apparatus further includes a first rotating member and a second rotating member rotatably connected around a common axis relatively with each other, to electro-magnetically control a driving torque transmitted from one of driving force transmission axles to the other thereof. A frictional engage section is provided between the first and second rotating members, to transmit from one of the first and second rotating members to the other thereof. Between the first and second rotating members, there is provided an annular electro-magnet to control a transmission torque of the frictional engage section. Further, an engage member provided on a support bearing to be engaged with the electromagnet to prevent rotation of the electromagnet with the first and second rotating members.
