From the Porsche link that Guenter provided,
"The gearbox is bolted to the body by two mounts. Like any mass, it obeys the law of inertia. This means that it will continue moving in a uniformly straight line unless some force causes it to change direction. Put more simply: when you are driving into a bend, the vehicle will follow your steering but, at first, the mass of the drive train will not. This means that the rear of the vehicle will ultimately be pushed outwards as a result of the drive train’s force of inertia. Dynamic gearbox mounts minimise this effect."
LIke any mass, it obeys the laws of inertia, but the DGM somehow changes (minimizes) those laws? How is that?

From a Porsche link on the dynamic engine mounts; I'd guess the tranny mounts use the same technology:
www.porscheengineering.com/.../Porsche-Download.pdf?...
"This is the result of a change in the hardness of the mount caused by a magnetizable (magneto -rheological) liquid and an electrically gen -
erated magnetic field."
That should clarify it; a fellow by the name of Tom Swift has the patent on it.

They stiffen with relatively steady-state forces, but are otherwise soft to absorb high frequencies. Laz - Saturday, 7 July, 2012, at 2:04:58 pm |
Lotus started experimenting with this about 20 years ago. *NM* Laz - Sunday, 8 July, 2012, at 9:57:18 am |
