Do you know the California Freeway Hop? No, it is not the latest trendy dance move from the kids. It is what happens when body-on-frame vehicles have soft mounts at the C pillar and the high energy of the frame leads the cab to literally bounce when excited by road inputs. The reason is simple: The frame comes with a natural beaming frequency of 7 to 14 Hz. Unless dampened at four times the rate of a typical hydro engine mount, this effect can cause significant discomfort for both passengers and load.
The hydraulic technology with its cycling fluids reduces the measured vibration by up to 50% and more and is typically used in
- Light trucks,
- Pickup trucks and
- Potentially vans, RVs and other small commercial vehicles.
