Air Suspension System

About

Background Suspension systems are used to reduce vibrations/shocks transmitted to the vehicle body from the road/terrain being travelled in order to enhance driver/passenger comfort and protect cargo and chassis. Typical designs are a compromise between performance measures such as vehicle ride, handling, load capacity, size constraints and energy consumption. The University of Waterloo is actively seeking automotive suppliers and manufacturers interested in commercializing an innovative, highly tunable air suspension system. Description of the invention The new technology developed by University of Waterloo researchers provides for a new class of road-adaptive suspension systems capable of independently tuning suspension stiffness and vehicle ride height corresponding to road conditions. Utilizing two pressurized chambers and a unique pneumatic control design, easy modification of suspension stiffness and ride height is made possible. Advantages Highly flexible system allowing for: Independent tuning of stiffness and ride height Large static load variations Large dynamic loads Ride handling and comfort High durability, low weight, complexity, and maintenance costs Stiffness and damping control Enables real time tuning to suit road surface Potential applications On/off-road vehicles Passenger cars, trucks, buses Military vehicles Stationary equipment Reference 8810-7287 Patent status Issued U.S. patent, Canadian, and PCT patent applications
