<p>PURPOSE:To carry out the fine torque control by installing an electromagnet for tightening a frictional clutch by transferring an armature by the magnetic force of a plurality of electromagnetic coils and a selecting means for selecting the connection of electromagnetic coils. CONSTITUTION:A clutch drum 41 is installed integrally on a connecting shaft 31, and a main damping clutch 59 is installed between a hub 43. A frictional clutch (pilot clutch) 69 is installed between a cam ring 63 and the clutch drum 41. An electromagnet consisting of a yoke 75 and electromagnetic coils 77 and 79 is arranged, and the lines 87 of magnetic force are led to an armature 71. When the armature 71 is attracted by the electric magnet, the pilot clutch 69 is tightened, and the connecting shaft 31 side and a drive pinion shaft 51 side are connected. The connection of the electromagnetic coil is selected by a selecting means (controller) 101. Accordingly, fine torque control is carried out by adjusting the electric current.</p> |
