Abstract: The present invention relates to a motor-driven unit for an automotive vehicle brake system comprising a housing body for magnetic valves and a cover located on one side, especially for electrical structural elements used to control the magnetic valves. An attachment means is interposed between the cover and the motor housing in such a manner that the latter structural elements can be attached to the housing body with the same contact force. These features permit rendering the sealing effect more uniform in the area of the electronic unit and in the area of the motor housing. In addition, the result of the arrangement of the attachment means is material economy and a reduced assembly effort.

Abstract: A disc brake caliper including a brake piston movably arranged therein. The brake piston is sealed in relation to the brake cylinder by a sealing ring, which is arranged in a circumferential annular groove of the brake cylinder. The sealing ring functions to retract the brake piston in the brake cylinder after a braking operation in order to provide a clearance between a brake shoe and a brake disc. According to the present invention, the annular groove includes a recess, which is arranged in the area of transition between a groove wall and the cylinder surface . The contour line, which defines the cross-section of the recess, starting from the groove wall of the annular groove, passes from a convexly curved portion over into a concavely curved portion. This permits ensuring an unchangingly constant clearance between the brake shoe and the brake disc roughly irrespective of the hydraulic pressure.

Abstract: To improve the steerability and the driving stability of a vehicle during cornering, the standard control mode is replaced by a special or curve control mode in such a situation in an anti-lock system. This special control mode reduces the brake pressure on the wheel at the inner side of the curve. When, during a braking operation and with the special control mode activated, there is a transition from cornering to straight travel, the pressure deficit on the wheel at the inner side of the curve which is caused by the special control mode is compensated by a special pressure increase mode, for example, by compressing the pressure increase pulse row.

Abstract: A fail-safe system 2, in which the position of an actuating device 4 is measured by three sensors 8, 10 and 12 that operate independently of one another. The sensor 8 is directly supplied with energy by a first energy source 20, and the sensor 12 is directly supplied with energy by the second energy source 22 of the system 2. The sensor 10 is supplied with energy by the first energy source 20 or by the second energy source 22 via a diode circuit 14, 16 such that, if one of the energy sources 20 or 22 fails, two of the three sensors 8, 10 and 12 are still supplied with energy. A majority decision can be carried out in the microprocessors 32 or 34 if the signal of one sensor is lacking, wherein it can also be determined which of the energy sources 20 or 22 has failed.

Abstract: An improved reverse rupture disc for use as a safety pressure relief device is provided. The disc is defined by an annular flat flange region, a concave-convex disc dome region and a transition region that joins the disc-shaped flat flange region to the concave-convex disc dome region. One or more deformations may be formed at or near the apex of the disc dome region for weakening the disc to the point that incidental damage to the disc will not weaken the disc any further, thereby ensuring that the disc will reverse at a certain pressure, and no lower. The disc may also formed with one or more irregular transition regions at the base of the disc and a partial circular groove in the transition region. The irregular transition region of the disc cooperates with a shear enhancing means such as a protrusion or notch formed in a support ring or disc holder disposed downstream of the disc to sever the disc dome from the annular flat flange region along the groove in the transition region.

Abstract: The invention relates to a method for determining the rotational speed of a motor vehicle wheel (4), which rotates about a rotational axis (2), by an acceleration sensor (10). The acceleration sensor (10) is mounted on the motor vehicle wheel (4) at a spacing (r) to the rotational axis (2) in such a manner that the force-sensitive axis of the acceleration sensor (10) is perpendicular to the rotational axis and is perpendicular to the centrifugal force which acts on the acceleration sensor (10) with a rotation of the motor vehicle wheel (4) about the rotational axis (2). The rotational speed of the motor vehicle wheel (4) is measured in that the rotational axis (2) is aligned horizontally so that a periodic measurement signal is generated in the acceleration sensor (10) by the gravitational force. The frequency of the measurement signal corresponds to the rotational speed of the motor vehicle wheel (4) about the rotational axis (2).

Abstract: The present invention discloses a method for use in automotive vehicles with an electronically controlled brake system (for example, ABS), wherein for controlling the braking pressure (re)increase during a control operation the rotational behavior of the individual wheels is measured and evaluated to determine braking pressure control signals, and wherein during a braking pressure control operation the braking pressure reduction in the previous cycle (26) is taken into account for the control of the braking pressure reincrease (27).

Abstract: Process and drum for constructing a green tire on a radially expandable drum having a substantially horizontal axis of rotation. The process includes collapsing the radially expandable drum at a minimum first diameter, and positioning a casing on the radially expandable drum to form a drum periphery being composed of an elastic material, and having an inner diameter at least as great as the first diameter, and including a plurality of voids coupled to an evacuating pump. The radially expandable drum is radially expanded from the first diameter to a second diameter greater than the first diameter to expand the casing, and producing a carcass, having at least one carcass ply with at least one of sidewalls and an air-tight inner layer, on the drum. A vacuum is produced in the voids to suction the carcass onto the drum periphery and at least axial end areas of the expandable drum are radially compressed to a third diameter to enable bead cores to traverse the drum periphery without touching the drum periphery.

Abstract: A method for manufacturing a pneumatic vehicle tire includes the step of folding the carcass ply in the overlap zone of the leading and trailing ends into at least one fold to form an overlength of the reinforcement elements in the overlap zone for preventing the constriction in the overlap zone within the vulcanized, inflated tire. Subsequently, in both methods, the green tire is completed on the building drum and the green tire is then vulcanized to produce the finished tire.

Abstract: In order to adapt a simplified vehicle model to the driving behavior of a real automotive vehicle, it is possible to modify the slip rigidity values assumed to be constant in a linear model. After departure from the linear range of the lateral-force/slip-angle characteristic, a lower value can be assumed for the slip rigidities. However, this will involve the risk that the wheels of the rear axle are already in a slip angle range to which the lower slip rigidity is associated whereas the front wheels are still in the linear range of the lateral-force/slip-angle characteristic. This would impart to the vehicle model an oversteering behavior which should the more so be avoided if such a vehicle model is used for presetting the nominal value. This problem is solved, in the practice of the invention, by suggesting to modify only the slip rigidity values of the front axle while the ones of the rear axle are assumed to be constant.

Abstract: The present invention discloses an electromechanically operable disc brake for automotive vehicles which comprises a floating caliper as well as an actuating unit arranged on the caliper. The actuating unit includes an electric motor which, by the intermediary of a reduction gear, readjusts an actuating element which is used to move one of two friction linings that are slidable in the brake caliper into engagement with a brake disc. To permit an individual adjustment of the desired brake force, especially for use of the disc brake in an automotive vehicle, according to the present invention, a force-measuring device (23) is interposed in the flux of force between the caliper (1) and the actuating unit (2), and the output signals of device (23) are adapted to be sent to a control circuit (26) that influences the current supplied to the electric motor (6), and/or the voltage.
