  • Patent number: 4824185
    Abstract: A hydraulic dual-circuit braking system comprising two main cylinders combined in twin-type construction which is actuated via a torque-equalized rocker operated by an actuating force proportional to brake pedal force, and wherein the main cylinders have position transmitters to detect piston positions, which are indirectly a measure of the brake pressure, and wherein an anti-blocking system enables the front wheel brakes to be blocked off from their main cylinders. The position signals are used by an electronic processing unit to determine the instantaneous front axle/rear axle braking force distribution, and compares this with a value which is ideal in accordance with the vehicle data, and when this comparison shows that the rear axle braking force component is too low, the front-wheel brakes are blocked off from their main cylinders until the rear axle braking force component is increased to such an extent that the ideal braking force distribution has been almost achieved.

  • Patent number: 4823645
    Abstract: An arrangement for adjusting the torque of an internal combustion engine which drives a change-speed gear box and automatic gear changing device in dependence on stored characteristics with specified variation of required torque value as a function of power demand in which at least two different gears are each associated with an individual stored characteristic. Switch-in signals, derived from the gear changing device and which initiate switching of a stored characteristic into an adjustment element which influences the torque, contain information on a gear to be selected. Engine power is at least approximately constant for each engine operating point in engine characteristic field when changing between two associated stored characteristics for the required torque value. An adjustment element is controlled by the switch-in stored characteristic until the gear changing device switches to the gear having a different associated stored characteristic.

  • Patent number: 4824363
    Abstract: A process and equipment for removing toxic and malodorous gases from the fresh air for vehicle cabins by catalytic oxidation, the process being based on passing the fresh air over a heating-system heat exchanger, the heat-emitting surfaces of which form the support for an oxidation catalyst. The heat exchanger used is the heating-system heat exchanger which is present in virtually all motor vehicles. In contrast to known solutions for purifying the fresh air, for example by means of activated carbon, the process is maintenance-free and does not require any additional constructional volume.

  • Patent number: 4822228
    Abstract: In a quick-action connection for retaining an insertion part in an orifice of a carrier, for example a holding nipple in a body wall, there is, in a peripheral groove of a tenon-shaped extension piece of the insertion part, a retaining ring resiliently flexible in the radial direction, which has its largest diameter in the inserted state of the insertion part. The retaining ring partially projects beyond the periphery of the extension piece and is supported on the carrier by means of one of its end faces. So that the retaining ring is capable of guaranteeing a reliable mutual connection of the two parts, even when bending moments are exerted on the insertion part inserted into the carrier orifice with a clearance fit, its annular shell is closed in the peripheral direction and extends in the form of a meander. As a result of this ring design, the retaining ring can be compressed radially in order to introduce the insertion part into the carrier orifice, and after insertion it automatically springs open again.

  • Patent number: 4821018
    Abstract: In a direction indicator and hazard warning device for motor vehicles, a time sequence control is provided, which, during hazard warning operation with a closed driving/ignition switch, allows direction indicator signals to be superimposed and, when the direction indicator signals are switched on, the hazard warning signal to be superimposed. The signal first selected is automatically generated once again after the added signal has been switched off. If, however, the driving/ignition switch is closed with the hazard warning switch and the direction indicator switch closed, the device causes the hazard warning signal to continue to be generated.

  • Patent number: 4815792
    Abstract: In an anti-blocking system for a road vehicle with statically pressure-actuatable brake circuits, a pressure modulator with an outlet pressure connected with the wheel brake cylinder is coordinated to each wheel brake, whereby pressure reduction-, pressure build-up and pressure-maintaining-phases of the anti-blocking regulation are attainable by its controllable volume change respectively maintaining constant of its volume. The pressure modulators are constructed as stepped cylinders with bore steps of different diameters passing over one into the other, in which a smaller and a larger control pressure space is movably delimited by piston steps of corresponding different diameters of a stepped piston, as well as the outlet pressure space, which is formed by an annular space remaining between the piston steps. The larger control pressure space is permanently connected with the main brake line of the respective brake circuit.

  • Patent number: 4813601
    Abstract: A piezoelectric control valve, for motor fuel injection via an injection valve, includes a hydraulic play-compensation element inside the control valve on the one side, which automatically compensates for possible changes in length of the reference system as a result of piezoceramic setting actions in the piezoelectric actuator so that, at the same working stroke of the piezoelectric actuator, an identical stroke at the valve is also always ensured. A hydraulic stroke transmission inside the control valve on the other side, provide a valve stroke corresponding to a multiple of the working stroke.

  • Patent number: 4811700
    Abstract: A drive unit comprising a reciprocating-piston type internal combustion engine and a transmission and output shaft is disclosed in which the sound-generating parts of the internal combustion engine are combined to form one driving mechanism body which is supported via an element which transmits power and isolates structure-borne sound, at the engine casing constructed as a noise capsule. To prevent sound from being radiated from the transmission casing towards the outside and structure-borne sound from being transmitted to the noise capsule, the transmission casing is rigidly connected to the driving mechanism carrier and the noise capsule also encloses the entire transmission casing.
