Patent number: 8882116Abstract: The present invention provides a passive vehicle suspension system providing optimal camber gain and avoiding the “bump camber” problem. This vehicle suspension system utilizes a conventional sway bar and a kinematic system to rotate the tire(s) of a vehicle in a direction opposite the roll of the vehicle during turning or cornering, for example. The kinematic design allows for adjustability and optimization, providing optimal camber gain. Although an automotive vehicle suspension system is illustrated and described, and, specifically, a racing or everyday automotive vehicle suspension system, the concepts of the present invention are capable of much broader applicability.Type: GrantFiled: February 28, 2011Date of Patent: November 11, 2014Assignee: University of North Carolina at CharlotteInventors: James Franklin Cuttino, John Stewart Shepherd

Patent number: 8870206Abstract: Disclosed herein is a novel suspension concept specifically designed for handling quality as well as travel and articulation. The foundation for this concept can be viewed as the integration of two different types of independent suspension systems—the double wishbone independent suspension system and Ford's twin I-beam front suspension system. Included in this concept is a novel configuration of two pairs of links per wheel whereby the length of each link in one of the two pairs pair is analogous to the vehicle's track width. Both spring and damping functions for the suspension system are provided by the novel segmented air shock absorber, this shock absorber being disclosed in U.S. patent application Ser. No. 13/854,055. This concept discussed herein is suitable for use on either the front or rear of a vehicle, that uniquely offers the handling quality like an independent suspension system and the travel and articulation capabilities potentially superior to that of a solid axle.Type: GrantFiled: October 21, 2013Date of Patent: October 28, 2014Inventor: Ronald Scott Bandy

Patent number: 8764040Abstract: A quadricycle includes a four-wheel suspension system that is structured to maintain contact between the ground and the wheels when traversing uneven terrain, as well as to permit a rider to lean into a curve in order to facilitate steering the vehicle. The suspension assemblies are relatively wide to resist rollover accidents. Shock absorbers within the suspension assemblies are angled from vertical to provide both a vertical force component and a horizontal force component in order to permit leaning into a curve while resisting excessive leaning. The quadricycle's drivetrain is structured to increase clearance between the ground and many drivetrain components. Smaller components of the spindle and wheel hub assembly are protected by larger components of the suspension assembly.Type: GrantFiled: February 28, 2012Date of Patent: July 1, 2014Inventor: Dennis DeLauter
