Abstract:
A part-lining disk brake is described, having an electromechanical actuator, a self-energizing application device with a wedge arrangement designed to press a brake lining against a disk brake, and at least two wedge elements of the wedge arrangement moveable relative to one another, arranged on one of a brake caliper frame and an auxiliary frame. The wedge elements are used to apply the brake lining, and act on the brake lining via a trapezoidal pressure plate.
Abstract:
A temporary voltage supply for a consumer includes a switching device with an auxiliary power supply; a control device supplied by the auxiliary power supply if an operating power supply fails; and a switching device which is activated by the control device and actuates the consumer via auxiliary power from the auxiliary power supply. The auxiliary power supply is configured in such a manner that, upon request, by actuation of a switch, the control device is provided with a sufficient amount of power for a final operating sequence after the operating power supply fails.

Abstract:
A disc brake is provided with an actuator acting on a brake application device, which brake application device is used for applying at least one brake pad to a brake disc. The brake application device has a brake-internal hydraulic arrangement and is configured in a self-energizing mode. The brake pad is supported on the brake application device at a wedge angle and the wedge angle of the brake pad is adjusted by the hydraulic arrangement of the brake application device.
Abstract:
A circuit configuration for inductive displacement measurement using a sensor whose inductance changes as a function of the displacement to be measured, and having an evaluation circuit to which the sensor is connected. The sensor is connected between a first operational amplifier and a series connection of a second operational amplifier and a resistor. The first operational amplifier is switchable over between two specified voltages and the second operational amplifier is operable to adjust a specified constant voltage at the connecting point between the resistor and the sensor, and the output of the second operational amplifier is connected to an input of a comparator whose other input is switchable over between two specified voltages. The output signal of the comparator effecting the switchover of these voltages and the voltages of the first operational amplifier, and is the measuring output signal of the circuit configuration at the same time.
Abstract:
Control of a microcomputer performing a wide variety of functions in a motor vehicle in which the sequences of input and output signals intersect in time, instead of being performed by an elaborate input/output unit, is performed in the microcomputer itself with the help of a timing signal generator operating at a sub-multiple of the microcomputer clock frequency and producing a sequence of timing signals, each of which serve as an interrupt signal to the microprocessor of the microcomputer to initiate an interrupt program for scanning inputs and preparing outputs. After this short interrupt program, the main program is resumed. In the interrupt program each of a number of registers, respectively serving separate inputs or outputs, are decremented or incremented, having been set at particular values at the beginning of each interrupt program. Some registers are set at two different values in alternation in succeeding interrupt intervals. Engine speed determination is produced by counting the number of interrupt signals during the passage of a prolonged signal representing a certain angle of shaft rotation. The frequency of timing signals is varied in steps in accordance with engine speed.
Abstract:
A method and device for correcting an error caused by electromagnetic interference, in a signal of an inductive displacement sensor or angle sensor, in that when known activation of at least one component which causes electromagnetic interference occurs and there is a known error resulting therefrom in the sensor signal of the inductive displacement sensor or angle sensor the error in the measured sensor signal is corrected.
Abstract:
A clutch actuator is provided for operating a clutch between a drive motor and a gearbox on a motor vehicle, in particular a commercial vehicle, including a linearly operating pin, acting on a release mechanism which is coaxial to a mid-axis of the clutch. The pin is arranged in a plane essentially perpendicular to the mid-axis of the clutch and coupled eccentrically to a rotating body of a gear mechanism, converting the rotating movement thereof into a linear movement of the release mechanism.

Abstract:
To provide for adaptive change of the operating characteristics of an engine, so that it will operate at its optimum effectiveness, just below the knocking limit, while reliably preventing knocking thereof, a computer receives engine data from respective sensors and a knock sensor (5), from which the computer calculates, based on data stored in a memory (3), operating parameters for the engine (1). The engine is, for example, an Otto-type internal combustion engine (ICE) or a Diesel engine. The operating characteristics, as computer-modified based on sensed knocking, and the modification data, are then placed into the memory to modify the basic memory content. Preferably, the memory has a basic memory content section and a programmable differential or modification section, in which algebraic constants or modifying factors are stored, based on actual experience of operation of the engine, just under the knocking limit. Thus, the stored data on which the engine operation is controlled is continuously up-dated based on actual engine operating conditions, and thereby compensating for ageing, wear and tear of parts, different fuels, or environmental conditions or the like. The computer can likewise recognize substantial deviation of the modified characteristics from the basic characteristics and, if the modifications exceed a certain limit, provide an error or malfunction output signal to an error or malfunction output indicator (9, 4) and go into a fail-safe mode.
