Patent number: 6672606Abstract: An improved suspension system is disclosed for a personal mobility vehicle comprising an arm assembly pivotably mounted to a fame section. A wheel assembly is connected to the arm assembly. A spring is interposed between the arm assembly and the second frame section for resiliently suspending the wheel assembly relative to the frame section. In one example of the invention, the frame section comprises a rigid frame section of the personal mobility vehicle. In another example of the invention, the frame section comprises a resilient leaf spring resiliently suspending the assembly of the personal mobility vehicle. In another example of the invention, a resilient coil spring interposed between the arm assembly the resilient leaf spring for providing a multiple resilient suspension for the wheel assembly.Type: GrantFiled: October 4, 2001Date of Patent: January 6, 2004Assignee: Electric Mobility CorporationInventors: Edward Joseph Dwyer, Jr., Stephen John Jarema

Publication number: 20030230866Abstract: A compact shock absorption, vibration, isolation, and/or suspension device is provided having long life and increased performance in a compact design. The device of the present disclosure is both less expensive and simpler to manufacture. In addition to being able to be used as a shock absorber in the hub of a wheel of an in-line skate, scooter or other small wheeled vehicle, the device of the present disclosure may be used in locations outside a wheel hub as well as in non-wheel devices where there is a need to isolate, damp, and absorb shock and/or vibrations experienced by a component of the device in order to minimize their effect on the entirety of the device.Type: ApplicationFiled: March 31, 2003Publication date: December 18, 2003Inventor: Elmer Lee

Publication number: 20030038445Abstract: A mobile vehicle suspension containing a leaf spring or set of leaf springs engaged between a forward frame bracket and a rear frame bracket; the frame brackets being engaged to face of the frame rail for each frame rail. The leaf spring is engaged to an axle through a pair of U-bolts. There is a U-bolt seat with a widened rubber spring engagement face; the U-bolt seat is sandwiched between the curved portion of the U-bolts and the steel spring. There is also a rubber spring bracket engaged to each frame rail. Each rubber spring bracket has a rubber spring that is aligned to make contact with the U-bolt seat upon a modest increase in chassis load beyond a very lightly loaded condition. Thereafter the rubber spring remains in contact with the widened rubber spring engagement face.Type: ApplicationFiled: July 31, 2002Publication date: February 27, 2003Inventors: Anthony D. Sutton, Michael P. Bires, James J. Korson, Joseph M. Smith, Christian W. Bultemeier, Jeffrey T. Henry, Brian M. Millard, Ryan S. Rochester, Derek K. Warinner, Robert W. Pope, Paul L.

Patent number: 6499754Abstract: A suspension system for a vehicle includes two laterally spaced front and rear wheel assemblies, each assembly including a wheel and a wheel mounting, permitting movement of the wheel in a generally vertical direction, bounce support devices supporting the vehicle body, and roll control devices controlling roll attitude. The roll control devices include respective second coupling devices interconnecting the longitudinally adjacent wheel assemblies, and further include transfer devices interconnecting the second coupling devices of each pair of longitudinally adjacent wheel assemblies.Type: GrantFiled: December 20, 1999Date of Patent: December 31, 2002Assignee: Kinetic LimitedInventors: Christopher Brian Heyring, Alexander John Robertson

Patent number: 6454283Abstract: The present invention provides a suspension system for a light duty trailer which includes a pair of modules. Each module is provided on an end of the axle and includes a spring member, a tower for connecting a front end of the spring member to an underside of the light duty trailer, an air spring connected between the underside of the light duty trailer and the spring member, and a limiting assembly for connecting a rear end of the spring member to the underside of the light duty trailer. In operation, if no bumps or ruts are encountered, the spring member remains generally horizontal relative to the underside of the light duty trailer. If a bump is encountered, the rear end of the spring member moves upwardly relative to the underside of the light duty trailer and the air spring compresses. If a rut is encountered, the rear end of the spring member moves downwardly relative to the underside of the light duty trailer and the air spring expands.Type: GrantFiled: November 14, 2000Date of Patent: September 24, 2002Assignee: Trailair, Inc.Inventor: E.

Publication number: 20020113399Abstract: The S.S. Suspension is a pro-active progressive shocking system. The system consists of a front and rear mounted shocking system. The shock mounts adjust to compensate for the external forces on the vehicle. The shock absorbers are mounted to this mounting system in coil over fashion. The S.S. Suspension allows the tires on a vehicle to keep a more consistent and aggressive grip on the contact surface. The suspension allows the chassis to float between the front and rear shocking systems which creates nearly zero chassis roll and an extremely low center of gravity. The suspension system also allows for more controllable vehicle handling over unlevel terrain. This innovative design allows the vehicle to react separately from the suspension system.Type: ApplicationFiled: February 16, 2001Publication date: August 22, 2002Inventors: Marcus Shawn Fehler, Gregory Scott Bush

Patent number: 6386565Abstract: A traction device is provided that includes a rigid front mount assembly that may be clamped to or around the vehicle's leaf spring, thereby creating a positive displacement point for torque transmitted from the rear axle through a telescoping linkage. An advantageous shock absorption element associated with the telescoping linkage cushions forces transmitted therethrough. Free travel and pre-load adjustments are made quick and easy through a readily accessible adjustment mechanism. A preferred bracket design is also provided which ensures optimal force transmission and enhanced system strength and reliability. The traction device of the present disclosure may be included in original vehicle fabrication and assembly, or may be readily installed on existing vehicles without the need for welding or modifications to the chassis or rear axle housing.Type: GrantFiled: July 28, 2000Date of Patent: May 14, 2002Assignee: Moroso PerformanceInventor: Michael W.
