Patent ID: 7338036

Claim:
A switchable assembly bearing with hydraulic damping, particularly for supporting drive assemblies and/or gearbox assemblies in motor vehicles, comprising: at least one working chamber and one compensation chamber that are separated from one another by a dividing wall, said working chamber and said compensation chamber being hydraulically interconnected through a damping channel and at least one additional damping channel that are formed in said dividing wall, said additional damping channel being arcuately formed in said dividing wall and hydraulically interconnecting said working chamber and said compensation chamber through a connecting chamber, said connecting chamber housing a shut-off body separate and apart from said dividing wall that is displaceable from a first position that enables fluid communication through said connecting chamber and a second position that closes said additional damping channel to disable fluid communication through said connecting chamber, wherein said additional damping channel is configured and disposed relative to a symmetry axis of the bearing so that forces acting on said shut-off body through a hydraulic liquid counterbalance each other.
