Abstract
A ball screw drive having a threaded spindle and a spindle nut enclosing the spindle coaxially. At least two radially outwardly open channels are oriented axially in parallel and are simultaneously pressed into the lateral surface, the channels open toward a common front face of the spindle nut. Balls circulate in a helical ball race in the space between the spindle and the nut. A ball return guide has two ball deflectors and a transfer channel running therebetween. A drive element is operatively connected coaxially to the spindle nut and applies a torque onto the spindle nut. The operative connection between the drive element and the spindle nut is formed by a contact surface with a connecting contour and a catch element (designed such that in the assembled state it engages in one of the channels. The ball screw drive can be used as an actuating element.
