Electronically switchable engine mount

The intelligent engine damping

Soft absorption in the neutral position – dynamic suspension when driving. The LEMFÖRDER hydro bearings provide ideal damping in every situation.

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 suspension travel (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 suspension travel (1).

The advantages

The electronically switchable engine mount combines hard and soft suspension.

  • It improves vibrational comfort.
  • It improves the high frequency behavior.
  • The harmonization of the mount in terms of rigidity, damping positions, and neutral position behavior is customizable.

Conventional bearings: compromises in comfort

An engine does not vibrate in a uniform manner; when the vehicle is moving, completely different vibrations and noises are generated compared to when the vehicle is stationary. This places different demands 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

Switchable mounts: customizable mount harmonization

The electronically controlled engine mount from LEMFÖRDER satisfies 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.
