Abstract
A drive shaft for motor vehicles has a tubular shaft portion of synthetic plastic resin in which fibers are embedded. Metallic end pieces are in part received in and bonded to the shaft portion; connecting elements can be connected to the parts which project outwardly from the shaft portion. A method of making this shaft is also disclosed.
Claims10
Drive shaft, particularly for motor vehicles, comprising a tubular shaft composed of fiber-reinforced synthetic plastic resin and including a plurality of wound layers of resin-impregnated fibers, with the windings of the inner and outer layers being helical and having a low pitch, but for intermediate layers with a pitch angle of about 30.degree.-60.degree. and with the windings of successive layers crossing one another;
- a metallic end pieces at each axial end of said tubular shaft and having a smaller-diameter inner anchoring portion received in the respective axial end and bonded thereto, and a larger-diameter outer ring portion of one piece with the anchoring portion, said ring portion having an axial end face facing toward and bonded to the adjacent end faces of said tubular shaft so as to protect the same against ambient influences.
