Electronically Switchable Engine Mounts
Intelligent Active Engine Damping

The requirements for engine mounts are becoming more demanding. Modern engines work with cylinder shutdown, higher compression and speed reduction. They are designed to save fuel, keep up with the latest driving dynamics and to offer maximum comfort in the passenger compartment. This means minimal noise and vibration. With the self-developed 'active engine mount system', LEMFÖRDER exceeds these requirements. Electronically switchable engine mounts by LEMFÖRDER convince in every situation.

Electronically switchable engine mounts by LEMFÖRDER increase the possibilities of conventional hydraulic bearings. If you extend a hydromount with an actuator, equip it with sensors and a control unit, it can be actively controlled - according to the current requirements - and can adapt to any situation. Depending on the motor excitation frequency, the motor mount dampens either hydraulically, passively or actively. The isolation characteristic is calculated by the control unit and converted by the actuator so that no vibration is transmitted to the subframe of the car.

Electronically switchable engine mounts by LEMFÖRDER: this is intelligently designed engine suspension for today's and tomorrow's generation of engines.

Functionality of the switchable engine mount

Re. A: In the comfort position, the valve (2) is open and, as a result, permits the motion of the air suspension (3). The result is a soft range of spring (1).

Re. B: In the driving dynamic position, the valve (2) is closed and, as a result, permits the motion of the hydraulic area (4). The result is a dynamically hard range of spring(1).

Advantages of intelligent damping

The electronically switchable engine mount combines hard and soft suspension.

  • It improves vibrational comfort.
  • It improves the high frequency behavior.
  • The set-up of the mounts in terms of rigidity, damping positions, and neutral position behavior is customizable.

Conventional mounts: compromises in comfort

An engine never vibrates evenly; when the vehicle is moving, completely different vibrations and noises are generated compared to when the engine is idling.This imposes different requirements on the engine mount. Therefore, conventional engine mounts always represent a compromise: either ideal damping in the neutral position or an ideal damping when the vehicle is in motion.

Switchable mounts: customizable mount harmonization

The electronically controlled engine mount by LEMFÖRDER meets both requirements: a quiet neutral position and engaged driving dynamics. The switching function causes the air suspension to be utilized in the neutral position: the mount provides soft suspension. When the vehicle is in motion, the mount switches to hydraulic suspension with a greater freedom of movement for the connected components: the mount provides a harder suspension.
