A piston-rod assembly with a piston rod having at least one attachment at one end. The piston rod is fabricated of fiber reinforced composite. The piston rod has a body of fiber-reinforced ceramic with a basic matrix of carbon fibers or ceramic fibers or both wherein at least silicon carbide is embedded and with an open porosity, at least at the surface layer, of no more than 3% of the volume of that layer admitting lubricants into the pores. The at least one attachment (or) includes at least one component of a non-ceramic material that fits into and/or interlocks with the piston rod.

Piston-rod assembly

A resilient leg as part of an attachment for the wheel of a motor vehicle. The leg is provided with a piston rod ( ) that has a piston ( ) attached to it, that travels into and out of a housing ( ), that is attached at its outer end to the vehicle's chassis, and that is maintained in radial alignment by two separated bearings. The piston divides the interior of the housing into two fluid-charged chambers ( & ). The object is to ensure satisfactory transmission of moments of force from the piston rod to the housing in a leg that is light in weight. The piston rod accordingly extends through, and is maintained in radial alignment at, both ends of the leg.
