摘要： A pneumatic brake booster for a motor vehicle having a booster housing, the interior space of which is divided by at least one axially movable wall loadable with a pneumatic differential pressure into at least one working chamber and at least one vacuum chamber. The movable wall includes a diaphragm plate and a rolling diaphragm which is arranged sealingly between the booster housing and the control housing, having a control valve which controls the differential pressure, is arranged in the control housing, and which controls a connection of the working chamber to the vacuum chamber or atmosphere, having at least one extraction duct which is integrated into the control housing for connection of the vacuum chamber to the working chamber, wherein the extraction duct can be blocked by the control valve. A device is also provided between the vacuum chamber and working chamber to improve the noise behavior.

摘要： A pneumatic brake booster for a hydraulic motor-vehicle brake system, including a booster housing, having a front and a rear housing shell, and at least one connecting pin, which is arranged in the booster housing such that the at least one connecting pin extends axially parallel to the center axis and which supports the booster housing from the inside by two supporting formations and which protrudes through the booster housing from the inside to the outside on at least one side by an end segment. In order to ensure simple intermediate handling of the brake booster before and during the assembly of the brake system and to improve the durability and corrosion resistance, the housing shells are arranged in such a way that the housing shells are each connected to the connecting pin such that the housing shells are secured against being axially moved apart from each other.

摘要： A pneumatic brake booster including a booster housing having at least one housing shell. The housing shell is designed to be substantially pot-shaped with a center axis, a base portion and a lateral portion, and the base portion has a curved or conical wall region. In order to offer a brake booster by which it is possible to cost-effectively realize improved adaptability to customer- and application-specific requirements with respect to the spatial connection arrangement, at least one flattened surface area is formed in a radial outer region of the base portion, is designed to be elongate in the circumferential direction and has, at its radial outer edge, at least two notches which are arranged with respect to one another in a defined grid pattern with a circle angle.

摘要： A braking device, for a motor vehicle brake system. The braking device has at least one movable activation element, at least one device for monitoring the position and movement of at least one activation element, and at least one compressible, electrically conductive device spring which is elastically prestressed between two abutments, wherein at least one of the abutments is of movable design, and the movement of the abutment is coupled at least partially to a movement of at least one activation element. The device spring is provided for moving at least one of the abutments into its unactivated release position. The invention proposes that the device spring be assigned a sensing function for monitoring the position and movement of at least one activation element. A degree of compression of the device spring can be sensed, and the device spring is arranged in an electrically insulated fashion between the two abutments.

摘要： A pneumatic brake booster having a booster housing. The booster housing has at least two thin-walled shell elements and an elastomer sealing element. The sealing element has a sealing bead, which is of encircling form radially at the outside, and at least one rolling diaphragm portion which adjoins the sealing bead. The sealing bead is sealingly clamped in a clamping space between the shell elements. The clamping space is formed by walls which are generated in the shell elements by deformation, its radial inner wall formed by a tubular, axially forwardly extending projection, which is folded at its front edge, of the second shell element. It is proposed that a bead-side rear wall of the clamping space is formed by an encircling, radially outwardly projecting collar which is formed on the second shell element.

摘要： In order to minimize spreading, without additional parts, of connecting bolts of a pneumatic brake booster in a manner which is brought about by the deformation of a bearing surface on a booster housing before and during its assembly on a provided vehicle body part, it is proposed that the bearing surface is assigned a planar surface section in an immediately adjacent manner which is configured so as to be plane-parallel with respect to the bearing surface and so as to be axially inwardly recessed on the booster housing with a circumferential step.

摘要： A pneumatic brake booster having a vacuum chamber and a working chamber in a booster housing separated from one another by an elastic diaphragm. The diaphragm bears in regions against a diaphragm plate axially displaceable between a zero position and a maximum stroke. An axial spacing between the zero position and the maximum stroke defines a stroke range of the brake booster. The diaphragm has a rolling fold which, during the displacement of the diaphragm plate, rolls on a rolling region on an inner wall of the booster housing. In order to offer a solution in which it is the intention for a modular system for different stroke ranges to be formed more efficiently and for the efficiency loss to be minimized or avoided, the booster housing has, in the rolling region, a tapered, conical portion with a cone angle ≥8° and an axial extent >⅓*stroke range.
