Embodiment Construction

[0026] figure 1is a schematic illustration of the torsional vibration damper 1 according to the first exemplary embodiment. The torsional damper 1 is arranged inside a wheel housing (not shown) of a motor vehicle and comprises a damper element 2 for a first mass arranged on the wheel suspension side and a second mass arranged on the body side. Relative motion between masses is attenuated. For example, the damper element 2 can be designed as an electrical damper.

[0027] The damper element 2 has a fixed (not shown) first damper part and a second damper part (not shown) inside the hollow cylindrical housing 3, the second damper part being able to form The damping force is supported in a rotational manner relative to the first damping part. The second damping part is connected via the deflection bearing 4 to a rod 5 (articulated rod), which can move or pivot under the action of the mass movement (see double arrow 5 ′) and is connected to the first mass. The rod 5 transmits a...

Abstract

The present invention relates to a rotating shock absorber (1) for motor vehicles, comprising at least one shock absorber element (2), the shock absorber element for attenuate the relative movement between the first mass of the wheel suspension side arrangement and the second mass of the body side arrangement. The shock absorber element (2) has at least one rotating damping portion, through a member (5) can make the vibration damping portion of the rotational movement, the member is mechanically coupled with the vibration damping portion and can be moved due to mass motion, wherein the member (5) and the rotating vibration damping portion between the mechanical motion coupling structure is built in at least one spring damping member (6).

Description

technical field [0001] The invention relates to a torsional vibration damper for a motor vehicle comprising at least one damper element for damping a relative movement between a first mass arranged on the wheel suspension side and a second mass arranged on the body side / damping unit. Background technique [0002] Damping the relative motion between two parts of a vibrating mechanical system is required in many technical fields. An example is a shock absorber on a motor vehicle body in the region of the suspension of the body on the chassis. For example, hydraulic linear dampers are used for this purpose. In corresponding linear shock absorbers, the connection points in the direction of force on the bodywork or on the wheel suspension are provided with elastomer bearings, so that vibration decoupling and thus, during operation of the motor vehicle, eg Vibrations due to the rolling of the wheels on the road are reduced. [0003] Rotational vibration dampers are an altern...
