    Abstract: An anti-skid brake system has a first brake circuit (I) terminating at two wheel brakes and connected to a dual-circuit master cylinder, a brake pressure modulation valve assembly and a recirculating pump. In an anti-skid situation, in order to reduce brake pressure, fluid is withdrawn from the two wheel brakes by the brake pressure modulation valve assembly and then returned to the master cylinder by the recirculating pump. Associated with a second brake circuit (I), which is likewise connected to the master cylinder and which terminates at two other wheel brakes, is a floating piston assembly connected to the first brake circuit (I). In an anti-skid situation, a pressure reduction, which is performed in the first brake circuit (I) by the brake pressure modulation valve assembly brings about a pressure reduction in the second brake circuit (II), via the floating piston assembly.

    Abstract: The anti-wheel-lock control system has a wheel speed transducer (1), an evaluation circuit (3), and a braking pressure control device (4, 5).Particularly in commercial vehicles and at low speed, the vehicle wheel may exhibit frictional oscillations; these frictional oscillations appear as rapidly changing speed signals when sensed by the value transducer (1), which simulate sudden high wheel speed. The invention addresses the problem of eliminating these disturbances. The changes in the speed signals are physically impossible, and the disturbances are eliminated by a circuit (15, 16, 27, 28, 29) which recognizes physically impossible changes in the wheel speed by comparing the actual speed signals with a simulation threshold at which changes in speed are physically impossible. This recognition circuit triggers an auxiliary device (18, 24) upon the occurrence of the disturbance, and the auxiliary device provides an auxiliary wheel speed signal for the control device based on wheel speed measured most recently prior to the disturbance.

    Abstract: 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.

    Abstract: To provide an unambiguously representative signal responsive to the speed of a vehicle wheel, an inductive pick-up (1a. . . . 1n) is coupled to a suitable star wheel or the like of each one of the wheels, the pick-ups then providing their signals to amplifiers (3a. . . . . 3n) having hysteresis characteristics. At low speeds, an offset signal is superimposed on the voltage from the inductive pick-ups so that the amplifiers respond and provide output signals only at higher amplitudes of the pick-up signals, thereby eliminating inaccuracies or disturbances occurring in the sensor which might simulate changes in speed of the respective wheel.
