Abstract
A ball screw drive which has a ball nut arranged on a spindle. The ball nut has a nut element and a deflecting element that deflects balls out of one end of an endless ball channel defined by the ball nut and the spindle to a beginning of the ball channel. The deflecting element is retained on the nut element through a clip. At least one clip leg of the clip has a first, resiliently biased section and a second section separated from the first section by a slit. The first section resiliently suspends the deflecting element on the nut element and the second section retains the clip inseparably on the deflecting element.
Claims15
A ball screw drive, comprising:
- a ball nut arranged on a spindle, said ball nut comprising a nut element and at least one deflecting element for deflecting balls out of one end of an endless ball channel defined by the ball nut and the spindle to a beginning of the ball channel;
- and
- at least one clip having at least one clip leg, the at least one clip leg comprises a first, resiliently biased section and a second section that is separated from the first section by a slit, said first section resiliently suspends the deflecting element on the nut element and the second section retains the at least one clip inseparably on the deflecting element.
A ball screw drive, comprising:
- a ball nut arranged on a spindle, said ball nut comprising a nut element and two deflecting elements for deflecting balls out of one end of an endless ball channel defined by the ball nut and the spindle to a beginning of the ball channel, the two deflecting elements are arranged behind each other on a periphery of the nut element and comprise on opposing ends engaging elements;
- and
- clips, which retain the deflecting elements on the nut element, having first clip legs and second clip legs spaced apart from one another and arranged on a periphery of the ball nut, the clips engage, via the first clip legs, the engaging elements of one of the two deflecting elements and the clips engage, via the second clip legs, the engaging elements of the other of the two deflecting elements.
