The MC Pierson strut with integrated wheel carrier is made of fiberglass and weighs only half as much as conventional steel struts. The design concept is based on use in mini and micro cars with a curb weight of less than one ton. The lightweight damper is in sync the overall concept of small cars: low weight, less fuel consumption and CO2 emissions, improved comfort, and noise reduction. In terms of durability, ZF engineers have broken new ground with the upside-down design of the cylinder tube, which offsets high bending stress.
Despite its considerable weight savings, the lightweight suspension strut has all the features of a modern damper – it is realistic in meeting market demands. In a further step, ZF is now working on transferring this lightweight technology to larger vehicles.
