Abstract

The disclosure concerns a multiple-spline hub that is particularly useful for a telescopic shaft for transmitting torque. There is a thin-walled tube section which is developed as a toothed profile tube having teeth of trapezoidal cross-section. There is a thicker-walled tube to which the connecting element of the telescopic shaft, such as a joint fork, is attached. The toothed tube section is inserted in the bore of the thicker-walled tube and the crests of the teeth of the tube section engage the interior surface of the bore of the tube. The crests of the teeth are bonded by brazing to the bore of the thicker-walled tube.
