Abstract: A torsional vibration absorber comprising a hub for attachment to a shaft and an oscillating ring. The oscillating ring is disposed concentrically with the hub and, together with the hub, delimits an annular gap. The hub and the oscillating ring are connected via connecting members made from an elastomeric material. The connecting members are offset in a circumferential direction and disposed in the annular gap. The connecting members include a bead-shaped middle portion, which is connected to the oscillating ring and to the hub via thin webs.

Abstract: A vibration absorber for damping vibrations of motor vehicle components. The vibration absorber comprises an absorber mass including a passage, and an elastomeric spring member inserted in the passage of the absorber mass. The elastomeric spring member comprises an outer sleeve connecting the elastomeric spring member to the absorber mass, and an inner sleeve for attachment to the motor vehicle component to undergo vibration absorption. An elastomer body interconnects the inner sleeve and the outer sleeve. The elastomeric spring member also includes a securing element. The vibration absorber includes stops that are spaced apart in an axial direction and that cooperate with the securing element to secure the absorber mass in the axial direction.

Abstract: A hydromount comprising a carrying mount and a support mount connected to each other by an elastomeric suspension spring. The hydromount includes a working chamber and a compensation chamber that are filled with a fluid and separated by a partition, and connected to each other via a damping channel inserted into the partition. The hydromount includes an absorber channel that is switchable via an actuating device. The absorber channel is inactive in a first switching position of the actuating device and active in a second switching position of the actuating device. The actuating device has an electrically drivable electromagnet and an armature suspended via an elastic membrane so as to allow the armature to vibrate. The membrane is surrounded by a limiting member such that the membrane abuts against the limiting member in the first switching position and is spaced from the limiting member in the second switching position.
