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 vacuum operated brake booster, comprises a casing including a base defining at least one hole, and at least one tube extending through the casing and configured to receive a screw for fastening the brake booster to a wall of a passenger compartment of a vehicle. The tube defines a rear end with a peripheral fold forming a rear groove, and an extension extending beyond the rear groove, the extension defining a first outer edge and being configured to be folded toward an outer side of the tube to form a crimping lip. The at least one hole is bordered by a recessed ring having a form complementary to that of the rear groove of the rear end of the at least one tube. The extension is configured to be folded above a second outer edge of the recessed ring and blocked in the groove.

摘要： A brake actuation sensor device is described for a brake system of a vehicle having a strain and/or compression gage which is reversibly variable in its extension, whereby at least one electrical property is able to be changed, and an evaluation device, by which at least one electrical variable is able to be ascertained with respect to the changeable electrical property, and, taking into account the at least one ascertained electrical variable, an evaluation variable is able to be determined with respect to a brake actuating force, the strain and/or compression gage being additionally developed so that the strain and/or compression gage is able to be situated in direct or indirect contact with a brake booster housing device in such a way that a force exerted on the brake booster housing device causes a mechanical stress in the strain and/or compression gage. Furthermore, a method is described for mounting a brake actuation sensor device of a brake system of a vehicle.

摘要： The present invention addresses the problem of standardizing a front shell of a booster shell of a negative pressure-type booster device by modifying the shape of a reinforcement rib provided to the front shell so as to satisfy the demand for varying the installation pitch and installation angle of tie-rod holes with one and the same front shell. A front shell configuring a booster shell of a negative pressure-type booster device in combination with a rear shell includes a reinforcement rib formed by bending the shells, wherein the reinforcement rib is formed along a virtual ellipse of which the center is located at the center of the front shell, with the major axes of the ellipse disposed on a line connecting the centers of two tie-rod holes provided in the front shell.

摘要： Provided is a negative pressure type booster device, in which a diaphragm of a movable partition wall has, in a penetration portion through which a tie rod bolt hermetically penetrates, a tubular guide portion that abuts against an annular flange portion provided on the tie rod bolt during forward movement of a power piston, and an annular sealing portion that is provided in the rear of the guide portion to block communication between a negative pressure chamber and a variable pressure chamber. The guide portion is provided with a communication portion through which a negative pressure chamber side space exposed by the front surface of the sealing portion communicates with the negative pressure chamber, even in a state in which the guide portion abuts against the annular flange portion.

摘要： A vacuum-operated brake booster includes a housing which consists of a bottom and a cover having an intermediate piston through which tubes, through which attachment screws are to pass, extend. The front end of the tube is threaded, and a peripheral groove is provided behind the thread, a flange being crimped in the groove behind the cover in the housing. The master cylinder is attached via the lugs thereof, which are fitted into the front end of the tube against the front surface of the cover and locked by the nut screwed onto the thread. The front end of the tube has a peripheral groove receiving the flange that consists of a ring and a sleeve, the lip of which penetrates into the groove by crimping. A gasket completes the seal.

摘要： A spacer for positioned a boost unit in an engine compartment of a vehicle. The spacer is defined by a wall located between a front face and a rear face, bearing surfaces, an axial opening with a flange thereon, ribs that extend from the flange to define a plurality of radial slots, an axial slot that extends from the front face toward the rear face and a peripheral slot that connects the axial slot with the engine compartment. A base of a boot that surrounds a hub on the boost unit engages the front face to define a flow path from the engine compartment to the hub. Tabs on the spacer assure that the front face is aligned with the base while the radial ribs prevent the base from engaging the wall to assure that the size of flow path remains constant during the communication of air to the hub.
