Abstract: This invention relates to a fastening device for a vehicle battery having a shell fixedly received in the vehicle for placing the battery and having a clamping bow which clamps the battery to the shell and extends in a U-shape over the battery. For reducing the manufacturing costs while the mounting times are shorter, the clamping bow is constructed as a one-piece U-shaped tension band made of spring steel with suspension hooks formed at the leg ends and a protuberance shaped out in the band web and pointing away from the battery top side. By pressing the protuberance flat, the suspension hooks can be hooked into corresponding suspension members on the shell, and after the release of the protuberance, the battery is force-lockingly fixed on the shell by means of the tension band.

Abstract: A seat testing punch is provided with an upholstered pressure element that can be used as a suitable aid in comfort comparison testing of different test seats to be performed according to strict test criteria, with which seat testing punch various test seats can be loaded in a realistic and reproducible manner as often or for as long as desired. For this purpose, the shape of the pressure element is made to simulate the pelvis and thighs, including the hip joints, of a human skeleton, at least as regards the underside. The upholstery of the pressure element likewise simulates anthropomorphically the soft parts in the area of the buttocks in terms of local distribution of thickness and softness. In particular, the two sitting pressure points of human buttocks and their immediate environment are simulated as naturally as possible in terms of shape, position, hardness, and local hardness distribution.

Abstract: Process and arrangement for controlling a motor vehicle diesel engine in which the fuel injection is limited as a function of a characteristic power limitation diagram and of a characteristic smoke diagram. As a function of the engaged transmission shifting position and/or of the vehicle speed, either a characteristic normal-operation smoke diagram or a correspondingly different characteristic starting-operation smoke diagram which, at a given rotational engine speed, permits larger injection quantity, are used as the injection-quantity-limiting characteristic smoke diagram. As a result, a favorable acceleration performance is achieved, particularly during the start of engines with a relatively small displacement.

Abstract: A fan-type manifold for multi-cylinder internal-combustion engines has several first individual pipe sections which are connected in pairs to respective ones of second pipe sections. The first individual pipe sections are undeformed on the end and are cut off at a specific angle. The second pipe sections are produced by an internal high pressure deforming process. The first pipe sections are plugged into the second pipe sections at respective Y-type combining points to form Y-shaped connections and are sealingly welded to each other via surrounding fillet welds. One of the second pipe sections has an additional Y-type combining point for the lateral connection of the other second pipe sections, which are sealingly welded thereto via surrounding fillet welds.

Abstract: A brake system is provided in which, in the normal operation, the brake pressure in the wheel brake cylinders is generated in a power-assisted manner and the master brake lines are closed by change-over valves. During a functional disturbance, the brake pressure in the wheel brake cylinders is built up by way of a master brake cylinder, such that, when the brake pressure control device operates normally also when the switching valves are closed the brake pedal can carry out a pedal travel and, on the other hand, when there are functional disturbances of the brake pressure control device, at most with a slight idling path of the brake pedal, by the operation of the brake pedal in the master brake cylinder and the wheel brake cylinders, a brake pressure can be generated in a conventional manner.

Abstract: A hydraulic feedback control for hydraulic power steering systems having first and second shaft sections rotatable relative to one another within limits, and whose relative rotation controls a servo valve system. At least one compressor working chamber is provided in the form of a piston working chamber. A piston is arranged in the piston working chamber, and is displaceable therein and separate from the first shaft section. The piston is tensioned by a pressure in a piston working chamber against a spring engaged with the first shaft section. A maximum possible displacement travel of the piston relative to the second shaft section is limited by a stop mounted thereon. The feedback control is designed so that with limited frictional losses, controllable torques can be produced which counteract the relative rotation between the shaft sections.

The discharge blower power is adjusted according to a curve as a function of this outlet temperature.

Abstract: In a shift device for a change speed gearbox, a shift shaft is kinematically connected to a selector sleeve which can be optionally braked tight, in such a way that when the selector sleeve is braked tight, axial movements of the shift shaft lead to superimposed rotational movements of the shift shaft, whereas when the selector sleeve is not braked, they lead to rotational movements of the selector sleeve.

Abstract: A method and an apparatus for testing the electrical connection of electrically controlled, electromagnetically operated injection valves of an internal-combustion engine which are equipped with solenoid coils. The cabling of such injection valves is tested in a non-contact manner by positioning a respective magnetic field sensor close to a respective injection valve within a magnetic stray field vicinity of the injection valves. A voltage is applied to the electric connection intended for the respective injection valve, and it is determined whether a magnetic stray field in the vicinity of the corresponding injection valve resulting from this voltage is detected by the assigned magnetic field sensor. The method and apparatus can be used to test whether the injection valves are correctly connected with the connection individually intended for them. The method and apparatus may be used in a bench test for an internal combustion engine.
