Title: Dean C. Karnopp: Inventor in Vehicle Suspension Technology.

Introduction

Dean C. Karnopp is an inventor associated with Davis, California. His patent work includes motor vehicle suspension technologies designed to improve vehicle-height control and manage the relationship between wheel and body motion. He holds 17 patents.

Latest Patents

Motor Vehicle Suspension System. This invention describes a suspension system in which each wheel has a spring and a hydraulic unit arranged in series. The system can adjust the vehicle body’s ground clearance at each wheel. A hydraulic feed system moves fluid between units to help counteract pitching and rolling.

Apparatus for Active Motor Vehicle Suspensions. This invention combines a fast-acting load leveler with active or semi-active dampers and passive suspension components. The arrangement aims to separate wheel motion from vehicle-body motion, damp wheel movement, and maintain an adjustable vehicle height.

Career Highlights

Karnopp’s professional associations include Robert Bosch and Aisin Seiki Kabushiki Kaisha. His patent work reflects an interest in vehicle suspension systems, hydraulic control, and ride-height management.

Collaborations

Karnopp’s listed coworkers include Yoshiyuki Yasui and Dietrich Sahm.

Conclusion

Dean C. Karnopp’s patents address practical challenges in motor vehicle suspension design, including adjustable ground clearance, load leveling, and control of vehicle motion.
