Overload protection for Dumper

News of  WEGU GMBH SCHWINGUNGSDÄMPFUNG

Many innovative products in the chassis

After us to continuously expand our market position in the field of exhaust technology in recent years, also we succeeded, to successfully acquire too many projects in the area of the chassis.

In particular, it is tuned mass dampers installed in the Audi, VW, Porsche, Skoda, and BMW. The most Fahrwerkstilger are bolted to the rear axle drive. The tuned mass dampers for the Skoda, however, is used directly in the drive shaft, there effectively to combat vibration problems.

With the dumper another precision component arrives at WEGU which makes highest demands on the responsible employees in manufacturing, the purchase of materials and the entire machine concept, as it was not yet known so far for WEGU.

The concept includes latest machine and tool technologies, a high degree of accuracy when passing the preheated Tilgermassen complex Formgeometrien a careful pretreatment of the individual components, and balancing out at 4,500 rpm in a clean cell. All of these features are required for the reliable production of this challenging article.

 

 

Tuned mass damper used, to reduce vibration tips that cause strength or acoustic problems. Vibrational energy is absorbed in the area of the Tilgereigenfrequenz of the tuned mass damper. This is removed by the absorbing properties of the rubber spring vibration energy the vibration-protected object. This minimizes the peak amplitudes occurring.

To accomplish this task during the entire lifetime of the vehicle, an overload protection has developed WEGU for Takahashi. This protection device is located in the Interior of the Tilgermasse as elastic buffers and guaranteed that the consistency of the Tilgereigenschaften be affected by shocks of the elastic structure to which it is attached to the tuned mass damper, neither short nor long term. Only at high temperatures. Tilgen heritage somewhat conditions, which can occur, for example, when entering a bad route, nestles the elastic stop at the cylindrical shaft of the fixing bolt and prevents excessive acceleration, which could lead to the failure of the TMD in this way.

Relative motion of the Tilgermasse over the bolts, that exceed a maximum amplitude, are slowed down by the elastic stop not only due to the structure of elastic forces, but also shares of the kinetic energy is converted into heat.

Under normal driving conditions, there will be no contact of elastic stop buffer with the fastening bolt. In these cases, the buffer then only within the space allocated to him moving.
