Abstract
The performance and cost gap between conventional rubber mountings and hydraulic damped mountings will be closed by a Pneumatic Damped Rubber Mount. Mainly for small size vehicles this concept offers a suitable compromise for shake and acoustics. Conventional hydrobushes for engine mounting systems have some general problems such as poor endurance life and acoustic performance. A new Hydrobush Design overcomes these difficulties by a multi material design. Certainly, more complex systems require switchable hydraulic damped mounts. In particular, Diesel Engines often need better isolation at idle operation. An Electronic Switchable Hydromount has been developed and checked successfully in different vehicles. Finally, active technology offers a huge potential to influence vehicle NVH performance. To substitute balance shafts or improve non-balanced engines a simple electronic Controlled Mount System cancels relevant shaking forces and even has the option to apply or cancel additional excitation orders to improve interior sound quality.
