Patent number: 8573616Abstract: A suspension system with inclination stabilization, in particular for use on heavy work vehicles, such as a dumper, where the front pair of wheels is mounted on a transverse rigid axle, has an axle (5) firmly connected with a Y-shaped frame (1) extending in the longitudinal direction along the central line (M) of the vehicle. The frame is suspended from the chassis of the vehicle, partly from a spherical bearing (4) disposed in the central line of the vehicle, partly via two spring units (2, 3) arranged symmetrically around the central line and a rod connection (7). The frame is additionally equipped with one or more laterally directed stabilization arms (6) which are confined by the chassis. This provides a suspension system which contains a very small number of components, which is stable, sturdy and resistant to wear, and which contains both springing, level adjustment and inclination stabilization.Type: GrantFiled: May 12, 2010Date of Patent: November 5, 2013Assignee: Hydema Produktion A/SInventor: Thorkil K Iversen

Patent number: 8544863Abstract: A damping and stiffness system for a vehicle suspension system including at least two forward and two rearward wheel assemblies each associated with vehicle resilient support means (27-30) between a vehicle body and the wheel assemblies. The damping and stiffness system including: a wheel ram (11-14) with at least a compression chamber (45-48) between each wheel assembly and the vehicle body and a load distribution unit (76). The load distribution unit (76) includes two pairs of chambers (77-80), each chamber (77-80) being divided into front (89, 90) and back (91, 92) system chambers (which vary in volume proportionally and in opposite senses therein with piston motion) and the remaining pitch chambers (93-96) by interconnected pistons (81-84) supported therein. The compression chamber (45-48) of each wheel ram (11-14) is in fluid communication with a respective system chamber (89-92) wherein the vehicle is primarily supported by the vehicle resilient support means (27-30).Type: GrantFiled: December 8, 2003Date of Patent: October 1, 2013Assignee: Kinetic Pty Ltd.Inventors: Christopher Paul Revill, Raymond Andrew Munday

Patent number: 8540257Abstract: A steering stabilizer includes a device connecting a fixed part of a vehicle to a steering mechanism of the vehicle, a control mechanism, and a centering mechanism. The control mechanism, which normally maintains an equilibrium configuration, includes a first member connected to a cylinder portion of a gas spring and a second member secured to a rod portion of the gas spring. A centering mechanism maintains alignment of the gas spring with the device. When the stabilizer is extended from the equilibrium configuration, the gas spring is activated to responsively and automatically return the stabilizer to the equilibrium configuration; and when the device is compressed from the equilibrium configuration, the gas spring is activated to responsively and automatically return the stabilizer to the equilibrium configuration.Type: GrantFiled: November 1, 2012Date of Patent: September 24, 2013Inventors: David Merchant, Tyler Swartz

Patent number: 8534433Abstract: An elastic connection element with variable rigidity for coupling together components that are spaced from each other. The connection element is a tubular component with coupling points which fix the components to the element. The rigidity of the element, in the state of maximum rigidity, is determined substantially by the coupling points. These are formed by a receiving eyelet and an elastomeric bush bearing press-fit therein. The region located between the coupling points forms a piston/cylinder unit, the interior of which comprises at least two chambers that are separated by the piston and which receive a hydraulic or a pneumatic medium. The chambers are interconnected with one another by a connection line containing a controllable valve. By at least partially opening the valve, the rigidity of the connection element can be reduced in relation to the state of maximum rigidity.Type: GrantFiled: April 6, 2009Date of Patent: September 17, 2013Assignee: ZF Friedrichshafen AGInventor: Klaus Kramer
