ContiTech has expanded its product range for industrial customers. The mounting specialist now also offers product solutions that offer a high level of protection against corrosion and more driving comfort thanks to hydraulic resistance. This makes them suitable for challenging applications as well.

Moisture, high humidity or an increased salt content in the air can lead to premature corrosion damage in metal components. For this reason, ContiTech Vibration Control has now developed new surface coatings for bearing elements. They protect Schwingmetall and Megi rubber-metal parts, which are used, for instance, as vibration elements in construction machinery and rolling stock, in applications that impose particularly high demands on corrosion protection.

ContiTech offers the industry particularly durable products with the new coatings: “The components were used in over 1,000 test hours of standardised salt spray testing without red rust appearing,” reports Dr Stefan Narberhaus, head of Industrial Development at ContiTech Vibration Control.

The engineers achieved this result with different variants of the optimised electroplated coatings. Metal ions settle on the vibration elements in this process and thus prevent the corrosion process. The rubber-metal element can then be given an additional protective coat. The type and thickness of the coats are optimised for every application.

The coated rubber-metal components are available as special designs for the complete Schwingmetall product range and Megi brand portfolio.

Hydraulic resistance increases the vibration damping effect of suspension components. ContiTech knows how to use this effect. Its products include bushings and mounts that have an integrated fluid system. Compared to conventional mounts, they calm vibrations even more reliably, because the hydraulic medium creates an additional damping effect.

Hydro bushings can be used as engine and cab mounts in industrial vehicles, for example. Their special construction makes for optimal vibration damping and excellent driving comfort. The hydraulic medium moves within the rubber element with complete freedom. If the hydro bushing is stressed, the hydraulic medium flows through the narrow channels inside the bushing. The resulting flow resistance creates a counterforce to the externally generated shift. Thanks to this hydraulic damping, vibrations are mitigated and the comfort enhanced for the driver.

The ContiTech hydro bushing handles loads of 1,230 N to 3,000N and has impressive durability. Another advantage of the bushing is that it can be rotated along its centre axis. This simplifies maintenance work on vehicles on which the driver cab is tilted. 

Hydromounts with integrated absorbers also have an integrated fluid system. They reduce vibration in a targeted manner and improve comfort and user-friendliness in industrial vehicles. The special advantage is that suspension spring characteristics, damping behaviour and absorbing effects can be separately optimised for these elements.
