ContiTech AG Spring Strut Mounts - Anti Vibration Components for the Chassis Chassis Vibration Control

Spring strut bearings provide an elastic connection on the car body between the shock absorbers and the support spring (superstructure spring) in the case of front wheel suspension. The dynamic forces of the shock absorber and the superstructure springs are isolated from the vehicle body by the spring strut mount.

As a result, the vehicle body drones less as the result of road-related excitation. As the front axle is steerable and the spring struts rotate with the wheels, there is a need for antifriction bearings that the helical springs can use for support. Decoupled spring strut mounts must be configured in such a way that they can support the helical spring and piston rod separately.

ContiTech is a recognized development partner and original equipment manufacturer for the commercial vehicle industry with air suspension systems for buses, trucks, trailers and semi trailers. With its two product brands – ContiTech and Phoenix – it also covers the spare parts needs for virtually the full range of commercial vehicle applications.

Our complete replacement range encompasses air spring systems for use throughout the commercial vehicle. These include trucks (trucks/road tractors), buses, trailers/semi trailers, cabs and driver sea

To ensure good isolation of structure-borne vibration, bushings must be designed with minimal spring stiffness. What is more, very resiliently tuned bearings require long spring travel distances or markedly progressive spring stops for high force peaks. To dampen wheel body frequencies, rubber bushings with a hydraulic damping mechanism are used nowadays.

The damping maximum of the hydraulic bushings are attuned to the wheel frequency. In terms of stiffness and damping, hydraulic bushings exhibit a marked frequency-dependency that leads to a dynamic hardening of stiffness above the wheel's natural frequency.

Brake Vibration Absorber

The brake vibration absorber shown is attached to the brake calipers and serves to reduce brake caliper vibrations, making it possible to lessen or entirely eliminate specific brake noise. The elastomer spring, with high temperature- and aging-resistance, is made of synthetic rubber (SBR/CR).

Leaf Spring Absorber

Flexural vibrations of leaf springs on small transport vehicles are reduced with the leaf spring absorber shown here. This device reduces the vibrations introduced into the body, thereby lowering noise levels and improving riding comfort. The rubber spring is made of natural rubber and is characterized by low stiffness, high load capacity and long service life.
