Abstract

The invention relates to camshafts. Known camshafts are produced predominantly from solid castings on which selective hardening treatments are applied to produce the desired qualities at the bearing and cam surfaces. As this surface quality must be high, the manufacturing processes are expensive and time consuming. According to the present invention, a camshaft comprises a carrier tube (4) and separate cam-forming elements and/or bearing surfaces in the form of tube portions (5) secured thereto. Securement of the tube portions (5) to the carrier tube (4) may be by soldering or welding; shrink-fitting; mechanical or hydromechanical expansion of the carrier tube (4); or hydromechanical pressing of the tube portions (5) onto the carrier tube. The invention enables the individual parts of the camshaft to be produced separately, and in different materials, reduces the subsequent treatment required to the camshaft; and results in a cost and weight saving. <IMAGE>
