Abstract (en)
[origin: WO2013029842A1] The invention relates to an electromechanical brake booster (10) with a hollow spindle (16) and a hollow screw (19). The invention proposes producing threads (17, 21) by working metal and encapsulating them in tubular supporting parts (22, 23) injection moulded from plastic. The invention makes it possible to produce the hollow spindle (16) and the hollow screw (19) as composite parts.
