摘要:
An internal-to-vehicle mechanism for monitoring the air pressure of a tire of a vehicle includes a sensor, detecting the tire pressure, which rotates, together with an electrotechnical first device, synchronously with the wheel and which, as a function of the tire air pressure that is determined, modifies parameters of the first device, namely the energy uptake of the first device. A stationary electrotechnical second device radiates an electric and/or magnetic, in particular electromagnetic, field through which the first device passes at, preferably, each wheel rotation with an uptake of energy from the field. A monitoring device detects the energy uptake and/or energy release of the second device.

The brake system having an electrically controllable brake apparatus of a trailer, the brake apparatus includes a control unit which is connected via electrical lines to an electrical energy source of a tractor. In braking, electrical currents are brought about of such a magnitude as to cause severe voltage drops in long lines that the functional safety of the brake apparatus may be threatened. The brake apparatus therefore has an electrical energy storage device disposed on the trailer, which can be charged by an energy source of the tractor and can be discharged upon triggering of the brake apparatus of the trailer. Voltage drops in the relatively short lines between the energy storage device and the control unit are therefore minimum. The lines between the electrical energy source of the tractor and the energy storage device of the trailer are charged by only low charging currents. The voltage drop is therefore low despite the long line length.
摘要:
A brake regulating system particularly suitable for stabilizing the motion of a commercial vehicle is described, in which a control unit outputs, as a function of a number of input variables, a predefined manipulated variable for the brake pressure of each wheel of a commercial vehicle and/or a predefined manipulated variable for an output variable of the drive engine. For detecting the input variables, the input of the control unit is connected to a steering angle sensor for detecting a steering angle predetermined by the driver, to a sensor system for determining the yaw rate of the commercial vehicle, and to a first acceleration sensor for detecting the transverse acceleration of the commercial vehicle.

A method and an apparatus relate to the detection of a tilt tendency of a vehicle about a vehicle axis oriented in the longitudinal direction of the vehicle. For this purpose, for at least one wheel, a variable describing the wheel rotation speed and at least one variable representing the transverse dynamics of the vehicle are ascertained. As a function of one of the variables representing the transverse dynamics of the vehicle, braking torques and/or drive torques are briefly generated and/or modified at at least one wheel. While the braking torques and/or drive torques at the at least one wheel are being briefly generated and/or modified, and/or after they have been briefly generated and/or modified, a variable which quantitatively describes the wheel behavior is determined for that at least one wheel, as a function of the variable describing the wheel rotation speed of that wheel. As a function of that variable quantitatively describing the wheel behavior of that wheel, a determination is made as to whether there is a tilt tendency of the vehicle about a vehicle axis oriented in the longitudinal direction of the vehicle.
摘要:
A nuclear reactor plant includes a reactor pressure vessel having a core barrel supported on a cylindrical holding structure fixed in the reactor pressure vessel. The core barrel has a lower part with at least one elastically resilient segment. A projection disposed on the segment engages under the holding structure in such a way that a wedge-like gap is formed between a lower surface of the holding structure and the projection. A wedge is braced in the gap. A method is also provided for mounting the core barrel.

A core barrel for a reactor pressure vessel of a nuclear reactor plant has a carrying structure that is supported on an inner surface of the shroud of the barrel. The carrying structure receives a tension rod that extends parallel to the longitudinal axis of the barrel and braces the shroud in the axial direction.

A supporting arm of a passenger door of an aircraft, has a curved structure which forms hollow chambers and movably connects the passenger door to a frame on the fuselage. Receiving means one for the supporting arm for receiving connecting means which enable a movable connection on the one hand to the passenger door and a pivoting drive and on the other hand to the frame on the fuselage, so that the door is movable by means of the supporting arm on a linear-displacement path and a pivoting path. The structure of the supporting arm is formed from fiber composite, the structure-forming fiber composite being formed from individual structural elements. This fiber composite structure further improves the thermal insulation of the supporting arm and nevertheless achieves a further weight reduction of the supporting arm, while maintaining exacting structural safety requirements for the latter.

A method for stabilizing a vehicle in particular to prevent overturning, in which a strategy is selected from at least two different strategies as a function of a quantity describing or corresponding to whether an overturn tendency about a vehicle axis oriented in the longitudinal direction of the vehicle exists, and which may be determined at least as a function of a quantity describing or corresponding to the wheel behavior of at least one wheel, and which may also be determined a function of a comparison which is carried out as a function of a quantity describing or corresponding to the lateral dynamics of the vehicle and of a characteristic value that is determined as a function of a quantity describing or corresponding to the instantaneous friction conditions.
摘要:
A knocking sensor provides output signals which are compared in a comparator (14) with a reference (16), knocking signals (FIG. 3: U17) exceeding the reference (U16); during predetermined cyclically recurring test intervals (FIG. 2: 19), for example after each 1000 ignition events, a test signal is generated at a terminal (15) of a microprocessor (12) and applied to the comparator (14) to lower the reference level (16), so that noise signals will cause a simulated, or pseudo knocking signal to be generated. Simultaneous occurrence of the simulated, or pseudo knocking signal and test signals indicates appropriate function of the knocking system; failure of the pseudo knocking signal to occur with the lowered reference generates control output from the microprocessor, for example by retarding ignition of an ignition system (13).
