摘要： Fail-safe brake valve driver (10) is provided for controlling a dual coil (A,B) brake valve. A pair of identical circuits (12, 14) are each uniquely associated with one of the brake valve coils. By means of control of an operational amplifier (16) and dual-stage current driver (18), the circuits (12, 14) each provide one-half of the current necessary for achieving brake valve control under normal operations. In the event that one of the coils (A, B) or circuits (12,14) fails, relays (56, 156) are provided for removing the failed circuit or coil from operation and allowing the remaining coil and circuit to carry the full operational load.

摘要： The servo automodulator is intended for connection to the brake system of the tractor vehicle through a power pipeline, called the automatic pipeline, and a control pipeline called the variable pipeline. This device comprises a body with first and second inlet connectors for connection to the variable pipeline and to the automatic pipeline respectively, an inlet/outlet connector and an outlet connector for connection to a pressure reservoir and to the brake members of the trailer. A non-return valve allows air to flow from the second inlet connector to the inlet/outlet connector to supply compressed air to the reservoir. The body houses a valve system for putting the inlet/outlet connector in communication with the outlet connector when the first inlet connector is supplied with a brake-actuation pressure, and a brake-pressure modulator device which controls the opening of the valve assembly, and hence the brake pressure, in dependence on the load bearing on the trailer. The body also houses a distributor control member which assumes a normal working position, in which it allows communication between the first inlet connector and a control chamber of the brake pressure modulator when the second inlet connector is supplied with pressurized air. The distributor member can move to an emergency position, in which it cuts off communication between the first inlet connector and the said chamber and in which it puts this chamber in communication with the inlet/outlet connector, when the pressure upstream of the non-return valve falls below a predetermined value, for example as a result of rupture of the automatic pipeline.

摘要： A preselected parameter of the wheel brakes of a motor vehicle, to be equalized with respect to their braking force, is sensed. Such parameter is correlated with the amount of braking force being applied. A signal is generated by the preselected sensor, which is then used to control supplemental pressure-regulating valves, positioned in the brake pressure feed line to the respective wheel brakes. The parameter selected to be sensed can be, among other things, either the braking force or torque being applied or the wheel brake temperature.

摘要： A fluid pressure control system engages the power take-off of a tractor-trailer combination vehicle equipped with air brakes while simultaneously applying the parking brakes of both the tractor and the trailer. However, when the vehicle is to be moved and the power take-off disengaged, the vehicle operator must, in addition to moving the power take-off control to the position disengaging the power take-off, must also operate the parking control valves which release the parking brakes on both the tractor and the trailer. Accordingly, the parking brakes cannot be inadvertently released by merely disengaging the power take-off control, although engagement of the power take-off control automatically sets or applies the parking brakes on both the tractor and the trailer.

摘要： A method and a multi-circuit brake booster for feeding back disruptions of any arbitrary kind, even of an associated anti-skid brake system, to a then-changed brake pedal characteristic, the influence on the brake valve triggering being effected via a travel simulator device. The transmitting member in the travel simulator device is a travel simulator spring enabling a predetermined idle pedal travel, and this spring responds whenever, in response to an arbitrarily generated disruption signal, a lockable storage element assumes its other position and mechanically engages a transmitting member in the chain from brake pedal actuation to brake valve slide actuation in an arresting manner. Upon reaching a predetermined amount of biasing, as a result of the further compression of the travel simulator spring, the opening of the brake valve then takes place abruptly, with a corresponding increase in brake pressure and a corresponding increase in vehicle deceleration.

摘要： A dual-circuit pressure medium brake system is equipped with relay valves disposed ahead of the brake cylinders. Each brake circuit is equipped with a control also acting in the other circuit and overlapping each other, and a primary brake circuit is designed in such a way that it contains all control elements necessary for optimal brake pressure adaptation, while a secondary brake circuit is merely an auxiliary brake circuit without control elements. In this manner each brake pressure metering can be simultaneously adjusted. During the loss of the primary brake circuit, the secondary brake circuit guarantees a minimal brake pressure. Such a pressure medium brake system is preferably used in air brake systems of motor vehicles.

摘要： A pressure-medium brake system, which comprises multiple circuits and has associated with each brake cylinder or group of brake cylinders relay valves which are controllable by a control medium. Depending on the number of brake circuits and the kind of the respective control medium, the relay valves are provided with several, possibly different, control chambers. This results in an overlapping control which insures that each relay valve can even be controlled in the event that a control circuit has been lost. The brake system is preferably used in utility vehicles equipped with air brakes.

摘要： In a hydraulic motor vehicle servo brake comprising a tandem master cylinder (11), a brake valve (17) is provided which upon actuation through the brake pedal (16) applies, in controlled manner, pressure medium supplied by a hydraulic pump (18) connected to an intake reservoir (27) to the first master piston (24) and to a brake circuit (III) directly, to provide there a controlled pressure. A wheel slip brake control system at an initial slip of one or more motor vehicle wheels, will reduce automatically the brake force on the motor vehicle wheels to a value just sufficient to turn the wheels. Two switch valves (21, 21') to which the controlled pressure is applied are normally closed and open upon a beginning slip of one or several motor vehicle wheels to apply the controlled pressure to the master cylinder (11) from where the pressure medium is passed by way of two check valves (23, 123) to the pressure chambers located behind the master pistons (24, 80). The switch valves are actuated by way of a differential pressure control circuit (148) in response to exceeding a predetermined pressure difference in the two pressure chambers (76, 176) such that the switch valve connected to a defective brake circuit will be closed.

摘要： An automobile hydraulic braking circuit comprises two reservoirs in addition to the main hydraulic fluid reservoir. One additional reservoir can replenish the other which in turn can replenish the main hydraulic reservoir. A peristaltic pump controls fluid flow to the main reservoir from the adjacent additional reservoir. Probes in the additional reservoirs operate in conjunction with control circuitry to inhibit operation of the pump to prevent contaminated fluid from being supplied to the main reservoir.
