Abstract: The invention concerns a hydraulic actuating system for a parking brake of a motor vehicle, with which the parking brake is hydraulically set by means of a setting mechanism through the use of the pressure stored in a pressure accumulator and is mechanically locked in the braking position by a triggering device.

Abstract: 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.

Abstract: In order to provide a mounting element for a foot-operated parking brake in a motor vehicle, the said mounting element being fastened in the driver-side foot space in the region of connection of an end wall to an end-wall column by means of screw connections and having components of the foot-operated parking brake connected to it, in order to arrange these for use in the vehicle, the said mounting element being light and at the same time being cost-effective to produce, it is proposed to have a mounting element made of plastic, in which the connection points between the mounting element and components of the foot-operated parking brake which are fastened to it are designed as metal inlay parts injection-molded around with the plastic of the mounting element, and in which these metal inlay parts are arranged in the region of the screw connections which serve for fastening the mounting element to the body.

Abstract: In a parking brake for a motor vehicle, an operating lever is mounted pivotally on a console and an operating-lever locking pawl is mounted pivotally on the operating lever and has a second row of teeth which can be engaged in the first row of teeth for locking the parking brake. A cable-tensioning disc is rotatably mounted on a support arm which is pivotally supported on the console. An operating cable is fastened to the cable-tensioning disc such that it can be wound up by a cable-tensioning spring on the cable-tensioning disc, which is provided with a third row of teeth.

Abstract: 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.
