Abstract: A transmission apparatus is disclosed which can improve the locking response speed of a lockup clutch when an engine is driven by the output side, without largely changing the structure of the lockup clutch or the like. In the lockup clutch of this transmission apparatus, fixing portions (21a) for a support member (24) of a damper spring (23) are fixed to a plurality of portions on a predetermined circumference of a piston (21) which are inside a friction member (22). Projections (21b) extending in the radial direction are formed, at those positions of the lockup piston (21) which are inside the friction member (22) and sandwiched by the fixing portions (21a) for the support member (24) of the damper spring (23), to project toward a front cover.

Abstract: Eine Kopplungsvorrichtung weist eine axial schwimmende Lagerung eines Leitrades (128) eines hydrodynamischen Drehmomentwandlers mit einer Überbrückungskupplung (84) auf. Die schwimmende Bewegung des Leitrades (128) ist zu einer abtriebsseitigen Gehäusewandung durch einen Anschlag [170] einer Leitrad-Stütznabe (154) an einem gehäusefesten Radialstützelement (46) begrenzt, d.h. die beiden Anschlagflächen weisen gleiche Drehzahl "null" auf. Eine Wälz- oder Gleitlagerung zwischen Leitrad-Stütznabe und abtriebsseitiger Gehäusewandung ist dadurch entbehrlich. Zur antriebsseitigen Gehäusewandung ist die schwimmende Bewegung durch die Einrückbewegung der Überbrückungskupplung begrenzt.
