    摘要: The brake system includes a first and a second diagonal brake circuit distribution. A first 2/2-way valve is located in a first line between a master cylinder and a wheel brake cylinder of the front axle. On the wheel brake side, a second line, in which a second 2/2-way valve is disposed, branches off from the first line, leading to a wheel brake cylinder of the rear axle. A third line originates between the second multiposition valve and the wheel brake cylinder and has a pump, with which pressure fluid can be fed from the wheel brake cylinders to the master cylinder. Brake force distribution that is dependent on the dynamic axle load shifting, and within limits, individual-wheel brake pressure control if wheel locking threatens, are thus made possible.

    摘要: A hydraulic brake system for a vehicle with an anti-lock arrangement operable by wheel brake pressures are individually variable in front wheel brakes and rear wheel brakes, connected to diagonal brake circuits, of a four-wheeled vehicle, in order to reduce or eliminate a threat of wheel locking. The anti-lock arrangement has at least one return pump per brake circuit. The anti-lock arrangement is equipped with a total of four electrically controllable valves. In each of the brake circuits I, II there is one first valve between the master cylinder and a front wheel brake and one second valve between the master cylinder and the rear wheel brake. All the valves are embodied as normally open valves and are electrically closable. Inlets of each of the return pumps communicate directly with the respective front wheel brakes and indirectly with the rear wheel brakes through throttles. Check valves that open toward the inlets of the return pumps are provided in series with the throttles. The anti-lock arrangement creates the possibility that in the anti-lock mode, for instance in travel on an icy road, rear wheel brake pressures may be higher than front wheel brake pressures, to improve the braking action.

    摘要: The invention relates to a hydraulic brake system of a vehicle comprising one wheel brake valve preceding each wheel brake cylinder and one return feed pump connected parallel to each of the wheel brake valves and connected to the suction sides of the wheel brake cylinders. For anti-lock control, the return feed pump is put into operation, and by clocked triggering of a wheel brake valve of a vehicle wheel that is tending to lock, the brake fluid pressure in the wheel brake cylinder of this vehicle wheel is modulated. To realize a traction control device, the invention sets forth a switchover valve in a brake line from the master brake cylinder to the wheel brake cylinder of a driven vehicle wheel. By closing the switchover valves and driving the return feed pump brake fluid can be aspirated from the master brake cylinder by the wheel brake valve of the non-driven vehicle wheel and pumped into the wheel brake cylinder of the driven vehicle wheel, and by this feed pump a brake force can be generated in order to avert spinning of the vehicle wheel.

    摘要: The invention is based on a dual-circuit anti-lock vehicle brake system (10) with a tandem master cylinder (12), a switchover valve (14) following the latter, a brake pressure modulation valve assembly (18, 20) that has a brake pressure buildup valve (18) and a brake pressure reduction valve (20) for each wheel brake cylinder (16), and a return pump (24). To enable building up brake pressure rapidly for vehicle dynamics control, the invention proposes one additional pump (28) in each brake circuit (I, II), whose intake side is connected directly to the master cylinder (12) and which feeds in the direction of the wheel brake cylinders (16) connected to to this brake circuit (I, II). As a result, a brake pressure buildup is possible in each wheel brake cylinder (16), even when the master cylinder (12) is not actuated, which buildup can be modulated for individual wheels in a manner known per se.

    摘要: In a method and network component of a communications network for switching connections of low bit rate between input modules and output modules, the input modules and the output modules form a first switching level, and an ATM switching stage arranged between the input modules and the output modules forms a second switching level. In the first switching level, a number of low bit rate connections at the input module, which are to be transmitted to the same output module, are respectively merged by the input module into at least one ATM connection. In the second switching level, the switching through of the ATM connections for transmitting data in ATM cells ensues by the ATM switching stage. Subsequently, in the first switching level, the ATM connections which have been switched through are converted by the output module into the low bit rate connections. The combined switching in two switching levels represents an especially economical solution for functions specific to mobile radio and switching applications dealing with low bitrate traffic, by simultaneously assuring an acceptable speech quality with good exploitation of the ATM bandwidth.
