Component assembly comprising a component and an element having a head part and a collar arranged at one side of the head part as well as manufacturing methods

Abstract

A component assembly is described which consists of a component and an element attached to the component and formed as an alignment element. The element has a head part, a component contact surface provided at an end face of the head part and a collar arranged inside the component contact surface and projecting away from it. The collar has a cross-sectional shape which is non-circular. The collar is inserted with clearance into an aperture of the component formed complimentary to the cross-sectional shape of the collar and has outer surfaces which converge in the direction of the said end face of the head part and with respect to the central longitudinal axis of the element and form an acute angle with the latter. The marginal region of the aperture of the component adjacent to the component contact surface extends into recesses formed between the collar and the end face of the head part but does not reach the base of the recesses, with a free space arising which ensures a lateral alignment movement of the element relative to the component. An axial separation of the element from the component is prevented as a result of material overlap of the component material with the collar within the recesses. Elements and methods for manufacture of the component assembly are also claimed.
