Lightweight Front Axle Plastic Top Mounts

Reduce weight and provide high frequency isolation

Optimizes load transfers between the suspension and the car body

Allows to integrate more features directly in the mount

Top mount modules combine the top mount, bearing, spring seat, dust boot and jounce bumper in one module

Lightweight plastic component suitable for high frequency isolation

Top mounts connect wheel suspensions with the chassis and, together with coil or air springs, minimize a large part of road surface excitation so that unwanted chassis vibrations do not reach the passengers. The plastic top mounts offer significant weight reduction compared to conventional top mounts without compromising performance and additionally providing high frequency isolation.

Front axle top mounts also perform a damping function and are responsible for direct and precise handling and steering feel which are essential for the vehicle stability. The structural strength and robustness are also critical factors for the top mount as the part can experience peak loads of a couple of tons, for example, by driving through a pothole. The design of the part and its materials assure its robustness and stiffness and optimizes the load transfers between the suspension and the car body.

The plastic components offer an improved high frequency isolation performance which is also a relevant factor for electric vehicles. The weight reduction contributes to the reduction of the overall vehicle weight and helps reduce CO2 emissions or increase range in electric vehicles, whereas the compact design offers more flexibility and design space.

Integrated top mount modules

Vibracoustic also offers integrated top mount modules for light vehicles. These combine five separate parts – the plastic top mount and integrated bearing, spring seat, dust boot and jounce bumper – in one module. Therewith, the top mount module provides light vehicle manufacturers with space, weight and cost savings while consolidating the full strut function within a single solution.
