  • Publication number: 20120180200
    Abstract: A force limiting device comprises a housing defining an axially extending chamber containing a working fluid. A force transmitting member may be mounted for linear reciprocable movement inside the chamber under the action of external loads. An axial array of plates is floatingly disposed in the chamber between the force transmitting member and an end wall of the chamber. At rest, each plate is spaced from an adjacent plate by a gap occupied by the working fluid. When the force transmitting member is displaced towards the array of plates, the fluid in the chamber causes the plates to be successively pushed against each other, thereby causing some of the fluid to be squeezed out from between the plates.

  • Patent number: 8113322
    Abstract: Air suspension systems, devices, apparatus, and methods for allowing motorcycle drivers to increase and decrease compressed air supplies in air suspension devices. Deflating interior air springs/airbags (bladders) inside the devices allows for springs and pistons on shock absorbers in the devices to expand outward separating lower front and rear frame portions which effectively lowers the motorcycle to the ground surface and for the driver to have a firmer ride. Inflating the air springs/airbags (bladders) allows for the springs and the pistons on the shock absorbers in the devices to retract into the devices so that the devices have a more shock absorbing effect giving the rider a smoother ride, which also raises the motorcycles above the ground surface.

  • Patent number: 7958981
    Abstract: A shock absorber interposed in parallel with a suspension spring between a vehicle wheel and a vehicle body of a vehicle comprises a main piston (2) partitioning a cylinder (1) into a first operating chamber (R1) and a second operating chamber (R2), and connected to a piston rod (8). The first operating chamber (R1) and the second operating chamber (R2) are connected by a laminated leaf valve (V1, V2) under a first flow resistance. A passage (4a) connects one of the pressure chambers (R3A, R3B) partitioned by a free piston (5) and the first operating chamber (R1) under a second flow resistance. A passage (4b) connects the other of the pressure chambers (R3A, R3B) and the second operating chamber (R2) under a third flow resistance. The shock absorber displays stable damping force characteristics as a result of a spring (S) supporting the free piston (5) in a predetermined neutral position.

  • Patent number: 7950674
    Abstract: An air suspension system is configured to adjust and maintain a desired vehicle ride height and spring rate. The air suspension system includes a plurality of air spring assemblies that each include a piston airbag and a primary airbag mounted around the piston airbag. A controller receives ride height input data and adjusts pressures within the primary and piston airbags until the desired ride height and spring rate is achieved. The controller accommodates for system hardware differences by varying flow rates into and out of the primary and piston airbags relative to each other.

The second amplification stage is disposed in series with the first amplification stage and is adapted to increase the input stroke from the first magnitude to a second magnitude that is greater than the first magnitude to yield an amplified input stroke. The rod extends through the second amplification stage and is coupled thereto to transmit the amplified input stroke having the second magnitude.
