The invention relates to a method and a device for manufacturing T-pieces from an unbranched starting piece of pipe by means of internal high-pressure forming (IHF). For this purpose, the starting piece of pipe is placed in a two-part forming tool which gives the shape, can be opened and closed, surrounds the starting piece of pipe, and has a cutout corresponding to the desired shape of the T-shaped pipe branch. Placed in a sealing manner against the two open end faces of the inserted starting piece of pipe in each case is a plunger which is movable in the forming tool and can be pushed axially into the forming took in each case by a pressure cylinder. The interior of the starting piece of pipe is filled with pressure fluid by means of an opening in at least one of the plungers, prior to being placed on the plungers in a sealing manner. A fluid high-pressure is built up by pushing the plungers axially into the forming tool with high force and, thus initiated, by pushing pipe wall material axially towards the forming point, the pipe wall material is pressed into the cutout in the forming tool and the T-shaped branch is thus shaped. In order to be able to manufacture T-pieces with a curved branch, the end face of the T-shaped cutout for the pipe branch is supported with controllable force by means of a flexible mandrel.

In a method and apparatus for producing a composite component comprising a hollow profile and at least one injection-molded element, a hollow profile (3) is formed by means of internal high pressure fluid forming and is encapsulated with an injection molding material to form the injection-molded element. The hollow profile is expanded by means of internal high pressure in a closed combination tool comprising an internal high pressure forming tool element and an injection molding tool element, before it is encapsulated. The hollow profile is pressed on the tool engraving only locally in the region of the location to be encapsulated, keeping the outlet of the injection molding channel opening into the tool engraving clear.

The invention relates to a pedal bearing block for receiving a pedal. The pedal bearing block has a basic body, a connecting point for fastening the pedal bearing block to a front wall, and a bearing point 13 for receiving a pedal bearing. In order to produce the pedal bearing block compactly and favorably, the basic body of the pedal bearing block has a shell 1 and a reinforcing element 11 assigned to the shell 1.

An exterior module of a motor vehicle has an exterior panelling for a modularly constructed housing component. The exterior module has a multilayer construction, which includes an inner surface layer and an outer surface layer with an exterior skin arranged thereon, which forms the exterior panelling. At least the inner surface layer is a thermoplastic FRP surface layer having stiffening elements on the side facing away from the outer surface layer.

In a parking brake mechanism and installation method of the mechanism in a vehicle, the mechanism includes a wind-up device for tightening a brake cable which wind-up device can be locked by a locking member to prevent tightening during installation. The brake cable comprises two sections, which are joined outside the vehicle by a coupling member, which is installed while the windup device is locked. The locking member includes a break-structure so that, upon installation of the coupling member, the locking member can be broken by pulling on the brake cable to permit the brake cable to be tightened thereby rendering the parking brake mechanism operational.

A control housing module (1) for a combustion engine, with integrating and/or connecting and/or receiving structures for auxiliary components (2,3,4,5,6,7,8) and a rib structure. The control housing module (1) consists of a fibre-plastic composite, which has at least one insert (10) made from a flat fibre textile in a thermoplastic matrix. The rib structure made from injected reinforcing ribs (11,11a) is formed of a thermoplastic, which has short fibres made of a reinforcing material with a proportion by volume of at least 30%. The ribbing (11,11a) includes rib structures (11a) arranged according to the direction of force and regularly formed longitudinal, transverse and/or diagonal reinforcing ribs (11) that cross one another. A foam material is arranged in the spaces (13) between the ribs, the spaces being bordered by the ribs (11,11a).
