Abstract
Die Erfindung geht aus von einer Rohrplatine (10) fuer eine Wischeranlage als Traeger eines Wischerantriebs (18, 20) und mindestens eines Wischerlagers (36), das in einem Rohrstutzen (14, 68) am Ende eines Platinenrohrs (12) quer zu diesem angeordnet ist. Es wird vorgeschlagen, dass das Platinenrohr (12) und der Rohrstutzen (14, 68) einstueckig hergestellt sind und der Rohrstutzen (14, 68) eine Lagerbuchse (40, 42, 44, 46, 48) spielfrei haelt, die aus setzfreiem Metall besteht und mit Uebermass in den Rohrstutzen (14, 68) eingepresst ist.
DE 19833159 A UPAB: 20000323 NOVELTY - The bar tube (12) and tube support (14) are manufactured in one piece, and the bar support accommodates with no clearance a bearing bush (40) which consists of a set-free material and is pressed into tube support with interference. The bearing bush has a circumferential toothing extending in the axial direction. A bush of sintered material or plastic may be pressed into the bearing bush, and a coating of plastic may be injected into the bearing bush. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a procedure for the manufactured of a tubular bar in which the tube support manufactured closed by an internal high pressure process is centrally slotted on the end face sides and the resulting lobes bent over inwards at least on one side. USE - The tubular bar is for the support of a windscreen wiper drive on a motor vehicle. ADVANTAGE - The bearing bush and tube support deform in an elastic range to such a degree that during the whole service life a clearance-free frictional connection is maintained.
