Stanyl PA 46 Resin from DSM: Cooperation between Bozzio, DSM, Bern University and Dynamic Test Center Brings Safer Mobility for People with Disability

The joysteer X-by-wire system with precision gears made of Stanyl PA 46 resin from DSM Engineering Plastics is now in commercial production for the handicapped market and available from car modification companies in Switzerland, Germany and the Benelux. This rapid development from prototype to successful commercialization was achieved by the Swiss company Bozzio within record time of just three years. In this period, Bozzio obtained the strictest level of safety approvals for the European market (TÜV approval according to ECE-R 13H braking system and ECE-R 79 steering system), making joysteerx-by-wire commercially available to provide people with a disability a user-friendly solution to drive a car with safety and confidence. This is the first system with such a high safety level.

Matthias Hell, Bozzio CEO, explains “We are proud to have brought to commercial production this important advance for people with a handicap offering them greater mobility. Our patented joysteer X-by-wire system is the end result of intensive cooperation by material supplier DSM Engineering Plastics, Bern University for Applied Sciences, Dynamic Test Center (crash test) and many others.”

Bozzio now foresees a host of potential applications for their patented X-by-wire system in special-purpose vehicles, such as municipal and agricultural vehicles, unmanned vehicles, areas requiring a high degree of reliability and safety. As Hans Wennekes DSM, Business Development Manager Stanyl, states “This patented technology made available by Bozzio opens new opportunities for Stanyl polyamide 46 (PA46) resin in wide scope of special purpose vehicles.”

The joysteer system
The gears sets made from Stanyl polyamide 46 (PA46) resin in joysteer X-by-wire system translate the driver’s steering movements into vehicle control. Two joysticks are mounted and coupled electronically to the vehicles steering mechanism. The driver’s movement of the joysticks is computed by joysteer and the data sent to the control module that turns the steering column and thus steers the car. The Stanyl gears are part of the steering actuator module. Stanyl polyamide 46 (PA46) resin fulfils the essential requirements for dimensional stability, low wear and the ability to absorb vibration and noise. Stanyl polyamide 46 (PA46) resin has an extra strong crystalline structure which makes it highly suitable for demanding automotive and electronic applications.
