Abstract
A suspension system for a vehicle includes a dynamic absorber mass having a mass smaller than the sprung mass of the vehicle and a spring system supporting the dynamic absorber mass for out-of-phase coaxial motion with the vehicle and tuned to the ride frequency of the vehicle for damping ride frequency perturbations from the vehicle.
Claims15
A suspension system for a vehicle comprising:
- a dynamic absorber mass including the drive system of the vehicle, said dynamic absorber mass having a mass smaller than the sprung mass of the vehicle;
- and
- a spring system connecting the dynamic absorber mass to the vehicle and supporting said dynamic absorber mass for out-of-phase coaxial motion with the vehicle and tuned to the ride frequency of the vehicle for damping ride frequency perturbations from the vehicle, wherein said dynamic absorber mass has a frequency which is substantially the same as the ride frequency of the vehicle.
A vertical suspension system for a vehicle comprising:
- a dynamic absorber mass including the drive system of the vehicle, said dynamic absorber mass having a mass smaller than the sprung mass of the vehicle;
- a spring system connecting said dynamic absorber mass to the vehicle and supporting said dynamic absorber mass for out-of-phase coaxial motion with the vehicle and tuned to the ride frequency of the vehicle for damping ride frequency perturbations from the vehicle, wherein said dynamic absorber mass has a frequency which is substantially the same as the ride frequency of the vehicle;
- and
- two pairs of wheels, an axle interconnecting each pair of wheels, two pairs of suspension arms connected to said axles, one proximate each wheel, each suspension arm including two spaced links and four pairs of compliant members for interconnecting each of said links of each suspension arm to the vehicle for maintaining traction between the wheels and road and accommodating for uneven surfaces of the road.

A suspension system for a vehicle comprising:
- a dynamic absorber mass including the drive system of the vehicle, said dynamic absorber mass having a mass smaller than the sprung mass of the vehicle;
- and
- a spring system connecting the dynamic absorber mass to the vehicle and supporting said dynamic absorber mass for out-of-phase coaxial motion with the vehicle and tuned to the ride frequency of the vehicle for damping ride frequency perturbations from the vehicle, wherein the ride frequency is about 3.9 Hz and the dynamic absorber mass has a frequency which is the same as the ride frequency.
