Hydraulic engine mounts carry static and dynamic loads that are introduced into the vehicle by the power unit.

In low and high frequency ranges, hydraulic engine mounts provide a high degree of vibration isolation and at the same time maximum damping.

Conventional engine mounts can have a wide variety of designs. In addition to static loads, they also absorb dynamic loads. In low and high frequency ranges, conventional elastomeric motor mounts provide a high degree of vibration isolation. In addition to the design, the material properties of the elastomer material are an important design criterion.

Bush bearings are a separate form of both hydraulic and conventional design. Depending on customer requirements, bush bearings are mainly used in the chassis area or as engine bearing systems for electric vehicles.

Tuned Mass Dampers are used to reduce vibrations in a wide variety of vehicle areas. Used as tailgate absorbers, they reduce rattling or droning noises from the tailgate. Steering wheel absorbers also optimize the comfort behavior in the vehicle interior.

Torque struts are used to support the torque input of a power unit. They absorb torques from the drive train during acceleration or braking. Torque supports thus limit engine rolling motions.

It contributes to the overall rigidity of the vehicle and absorbs the forces and torque of the engine-transmission unit.

By using glass fiber-reinforced polyamide instead of aluminum, the weight of the part was reduced by 50 percent. As the central component of the rear axle, the transmission cross member made of glass fiber-reinforced polyamide is about 25 percent lighter than die-cast aluminum versions.

Exhaust isolators must perform in extreme temperature environments and meet NVH requirements as well as durability and strength specifications. Our high-temperature elastomers with silicone content and our EPDM-based compounds are designed and engineered to meet the specific requirements of each application.

The additional cost of dual compound technology is limited primarily to the additional cost of the additional waste from the second mold feed system and a minor increase in tooling to accommodate the dual compound design. The technology was developed in large part to bridge the cost and functionality of conventional and hydraulic bushings.

The technology can be used in a wide variety of components, such as.

• Twist-axle bushing
• Compound control arm axle bushings
• Trailing arm bushing
• Wishbone bushing
• Subframe bearings
• Torque arm
• Power unit bearing

Limiting driveline movement while isolating the high-frequency vibrations typically generated by transmission gears is achieved through component design and advanced compound development to lower dynamic hardening.

Chassis bushings, whether single, double or triple bound, are designed to provide the necessary mobility while guiding in multi-link suspensions while meeting NVH, strength and durability requirements.

Top mounts, whether for shock absorbers, spring-damper struts or McPherson struts, must work seamlessly with the suspension system in the chassis and also absorb the maximum loads that occur in rough road conditions. Elastomeric compounds are available to minimize noise transmission from the road surface while being designed to withstand the harshest loads from the chassis.

For the front engine mount, the subframe mounts must work in conjunction with the engine mounts and driveline suspension to isolate engine noise and road excitation. In today's situation, where weight is crucial for fuel economy, high-tech lightweight plastics and the use of lightweight aluminum can play a decisive role in reducing fuel consumption.
