Abstract
The disclosure relates to a threaded shaft for a roller screw drive, for example for an electromechanical brake booster or an electromechanical power steering system. According to the disclosure, a helical coil with a flat, square-threaded annular cross-section is arranged on a thin-walled pipe, the pipe being formed onto a root region of the helical coil by the application of high pressure from the inside of the pipe.
