Adjustable steering column assembly having self-de-lashing power-rake mechanism

摘要

A self-de-lashing power-rake mechanism of an adjustable steering column assembly of a vehicle is provided. The power-rake mechanism includes a jacket, rake bracket coupled to the jacket, and rake bolt extending through the jacket and bracket. At least one pivot bushing is disposed between the jacket and bracket and configured to receive and radially constrict around the bolt. A fastener is configured to be positioned onto the bolt, tightened, and seated on the bracket. The bolt is forced through the fastener, bracket, bushing, and jacket. The bolt is seated on the bracket as the fastener is tightened and draws the bolt, fastener, bracket, bushing, and jacket together as the fastener is being seated on the bracket, thereby de-lashing respective interfaces defined between and among the bolt, fastener, bracket, bushing, and jacket. A steering column assembly including the mechanism is also provided.
