TORSIONAL DAMPER FOR AN AUTO TRANSMISSION, CAPABLE OF IMPROVING THE DURABILITY OR A RIDE COMPORT OF A VEHICLE BY CONTROLLING GENERATIONS OF NOISES OR VIBRATIONS

摘要

PURPOSE: A torsional damper for an auto transmission is provided to enhance a diminution capability of a torsional damper with respect to an impact generated by a rotation driving force transferred from a crank shaft because the self-weight of the torsional damper or an inertia moment is increased.;CONSTITUTION: A torsional damper for an auto transmission comprises a disk plate(3), a hub assembly(5), and a torsion spring(7). The disk plate is connected to the crank shaft's opposite side of a flywheel(11) installed in an endmost of a hybrid vehicle's crank shaft. The disk plate is synchronously rotate with the flywheel rotating by a rotation driving force of an engine. The hub assembly is joined to a spline in an end part of a transmission intermediate shaft(13) to be faced to the disk plate. The hub assembly buffers the rotation driving force transferred from the disk plate. The torsion spring is arranged between the disk plate and hub assembly. The torsion spring outputs the rotation driving force input from the disk plate to the hub assembly.;COPYRIGHT KIPO 2012
