Modular Motor Mount Bracket with TPE Bushing

The compact polymer beam structure and the integrated thermoplastic elastomer bushings allow full integration, weight reduction and simplified assembly. The modular mounting solution is available with different levels of integration - raging from bushing to more complex beam structures which can be finetuned to specific stiffnesses and isolation requirements. The modular motor mount bracket and a highly-integrated beam mounting structure was specifically developed for BEVs to meet the requirements for EDU mounting.

TPE Bushing
The thermoplastic elastomer (TPE) bushing provides double isolation for improved efficiency, with the entire part acting as a damper. This mount offers cost savings through dual injection production technique and can be tailored to the desired stiffness by simply changing the geometry. The use of TPE in NVH applications is an innovative alternative to natural rubber.

Compact beam structure with integrated bushings
Our patented lightweight, compact composite or polymer ‘beam’ structure combines the same TPE bushings and double isolation technology while further optimizing NVH management. It provides significant weight savings of up to 25%, is smaller than comparable alternatives and simple to assemble which leads to reduced cost. Additionally, its plastic-based construction offers better isolation of higher frequencies, like those associated with EDU operation, when compared to a steel or aluminum solution. Our engineering team also integrated a damper mass into the beam’s construction which further optimizes NVH performance without compromising packaging.

About Motor Mounts

Motor mounts carry the static and dynamic loads of the motor throughout its entire service life and are also an important factor for isolating low to high frequency vibrations. Downsized and turbocharged motors are state-of-the-art to reduce fuel consumption but lead to high vibration levels.


Motor and transmission mounts consist of a motor or gearbox support arm, an isolation element and a body-side connecting element. The critical element is the rubber spring that dampens vibrations, supports drive torques and isolates noise during start-up. The motor mount prevents booming noises and load-change shocks. Vibrations of the body and drive train are improved by using a hydraulic damping system. Motor mounts effectively isolate motor vibrations and dampen road excitations to ensure a comfortable driving experience.

The product portfolio ranges from conventional rubber mounts and hydro motor mounts, through electrically or pneumatically switchable motor mounts, to gearbox mounts and torque rods.
