Abstract:
A front region of a motor vehicle has two front headlight groups and air inlet openings for the engine compartment, as well as a movable cover for both the front headlight groups and the air inlet openings. The air inlet openings are arranged above and/or below each front headlight group. At least one movable cover is provided for each arrangement consisting of a front headlight group and air inlet openings.
Abstract:
Brake-force control system (ABS) for vehicles, in particular motor vehicles, with separate control of the front wheel brakes and with joint or separate rear wheel brakes which can be switched over to "select high" control or individual control and/or with a limited-slip differential at the rear axle, the switchover of the rear wheel brakes and/or of the limited-slip differential being effected at different coefficients of friction (.mu.-split) with a specifiable rate of rise dependent on the travelling speed, and in which, in order to increase directional stability during a braking procedure, a switching device is provided which blocks a switchover of the rear wheel brakes and/or of the limited-slip differential until the travelling speed from the time of the detection of different coefficients of friction has decreased to a specified value, the rate of rise of the switchover being dependent at least one the duration of the reduction of the vehicle speed to the specified value.
Abstract:
A transverse guide roller for track-guidable buses effectively prevents the access water to the rotational bearing of such rollers housed rotatably in a horizontal plane. To this end, the rotational bearing is accommodated in a bearing bell which covers the rolling bearing arrangement in a protective and sealing manner. The wheel body has essentially the shape of a cup with an upwardly pointing opening and with a bearing journal projecting from the cup bottom. The rolling bearing is fixed on the bearing journal with the inner ring as a rotating rolling bearing ring. The cup bottom has, at its lowest point, several discharge orifices for the unhindered discharge of water which may have penetrated.
Abstract:
The invention relates to a sloping-edge-controlled fuel injection pump for internal combustion engines, in particular as a direct injector for commercial vehicles. A cam-operated pump plunger, defining the pump working chamber and having an upper control edge effecting the start of delivery and a lower sloping control edge effecting the end of delivery, is guided axially and in a rotationally movable manner in the pump cylinder and has two peripheral grooves which, with two bypasses in the pump cylinder, interrupt the delivery, each bypass, in the projection perpendicular to the axis of the pump cylinder, partly overlapping feed bores arranged in the pump cylinder.
Abstract:
A soot burn-off filter including a monolithic filter block made of porous ceramic with a multiplicity of channels which extend in the direction of flow of the exhaust gases of a combustion engine. The channels are sealed alternately at the ends by plugs and are separated from one another by porous partition walls. The partition walls are provided with a catalytic coating and have an increased flow resistance in a region at the downstream end of the filter, the partition walls in this region being of gastight design and the catalytic coating of the partition walls ending in a region upstream of the gastight region of the partition walls.
Abstract:
The present invention relates to an end connector for coupling at least two shielded cables having a plurality of cores, i.e., insulated wires, in such a way that the cables and the cores of the cables are insulated from one another at the connection point. An insulating body defines one or more insulating chambers into which the cables are guided. Desired cores of the cables are electrically coupled at end connection points of the insulating chambers. A cap is coupled to the insulating body to cover the coupled cores. The cap has a metallic outer surface and a hole. The shields of the cables are guided through the hole and electrically coupled to the outer surface.
Abstract:
An adjustment for vehicle shock absorbers provides for a variable difference between a damping coefficient for the tension stroke and the damping coefficient for the compression stroke. In response to constant short-stroke oscillations of the wheels caused by unevenness of the road, a particular shock absorber generates a force on the vehicle body, the amount of which depends on the difference. By an appropriate control of the forces from the shock absorbers, pitching and rolling movements of the body can be counteracted.
Abstract:
In a filter insert which is received exchangeably in a shaft along a channel and which can be fixed sealingly relative to frame shaped shaft walls via at least one gasket preferably continuous on a flow-off side of the filter, it becomes possible to change the filter easily, without the danger of damaging the gasket, if there is at least one pressing element which can be connected to a pressure reducing device. When the pressing element is in the contracted pressure reduced position, a continuous gap forms between the gasket and associated shaft wall during a shift of the filter, this gap being cancelled when the pressure reducing device is disconnected.
Abstract:
A motor vehicle with four driving wheels and driven differential gearing for the drive, where (in the case of rotational-speed differences occurring between the wheels) a control device intervenes to distribute the drive power of an engine to the permanently driven wheels and/or the other driven wheels. This intervention occurs for a particular holding time which is progressively extended if a new intervention by the control becomes necessary after a test disconnection of the respective intervention. In addition, or alternatively, the control device can respond more sensitively and thus more quickly to rotational-speed differences of the wheels which may later occur during, or after, a test disconnection.
Abstract:
A hydrodynamic torque converter has a bridging coupling. An axial piston arranged in the converter housing is subjected to a working pressure for engagement of the bridging coupling and to an internal housing pressure acting in the opposite direction. A sensor operative relative to a reference control pressure controls working pressure. To obtain an analogous dependence on the internal housing pressure otherwise measurable only with special measures, the reference control pressure is set by means of a pressure-regulating valve working as a function both of the inflow pressure and of the flow-off pressure of the hydrodynamic working circuit.
