New Products Developed to Improve the Isolation Qualities of Automobile Suspension Systems: “Torsidyne” and “Atadyne” 851651
Vehicle front suspension systems are designed to achieve the best possible compromise between comfort and handling. Some inputs into the system are isolated by parts that link the suspension components to the frame. This presentation addresses two of these connector applications. They are the suspension arm bushings and the upper strut cushion. Conventional products as well as new innovative C.P.I.O. approaches are discussed.
The TORSIDYNE slip bushing concept is applied to suspension arms. This approach replaces torsional rubber return with easy rotation while offering flexibility in the areas of radial, axial and conical rate.
The ATADYNE principle is discussed for usage in upper strut mount applications. In addition to other features, it maintains a variable variable vertical rate regardless of the mount operating position.
