  • Patent number: 9764724
    Abstract: A valve device for a pneumatically-operated vehicle brake system can adjust the pneumatic brake pressure that can be fed to a brake in a controlled manner. A first variant of the valve device is configured as a modulator for use in an electronically regulated embodiment of the brake system; and a second variant is configured for use in a pneumatically controlled embodiment of the brake system. However, both variants have pneumatic interfaces and mechanical fastening points that are configured substantially identically with respect to one another to facilitate conversion of the brake system from one such embodiment to another.

  • Patent number: 9676378
    Abstract: A valve device for brake control of a different pressure medium-operated vehicle brake systems comprises a housing that has pressure medium ducts. A relay valve provides a pneumatic control pressure, which is fed to the relay valve via at least one of the pressure medium ducts at a higher flow rate. At least one insert is pneumatically connected to at least two of the pressure medium ducts, which can be pneumatically connected to each other by the insert. The two pressure medium ducts define a pressure medium path, the profile of which differs based on the housing that is in each case selected and/or switched based on the selected insert. The housing is selected from a set of housings having different pressure medium ducts, in particular bores, but which are otherwise essentially similar. The insert is selected from a set of different inserts.

    Abstract: A pneumatically-operated vehicle brake system has a first compressed air line in which compressed air at a controllable service brake pressure can be provided. Membrane parts of brake cylinders can be ventilated by the service brake pressure for a service brake function. A parking brake device includes a second compressed air line in which compressed air can be provided at a parking brake pressure electro-pneumatically. Brake cylinder spring brake parts can be ventilated by compressed air at the service brake pressure to provide a parking brake function. The parking brake device also has a ventilation inlet by which the second compressed air line can be ventilated to increase the parking brake pressure, and a first ventilation outlet by which the second compressed air line can be ventilated to reduce the parking brake pressure. The second compressed air line can be pneumatically connected to the first via the first ventilation outlet.

  • Patent number: 8795136
    Abstract: An actuating device includes a vehicle operating brake and parking brake. A first braking effect is generated by the parking brake independently of a braking procedure for the operating brake. The actuating device comprises a first switched state, wherein the first braking effect of the parking brake cannot be provided, and a second switched state, wherein the first (full) braking effect of the parking brake is provided. The actuating device further comprises a manually actuatable operating element for actuating the parking brake that comprises travel positions. The actuating device is switched to the second switched state in a first travel position when the parking brake is released, and to the first switched state when the parking brake is applied. Also, the actuating device is switchable to a further switched state. In an actuating method, the actuating device is switched to the further switched state in response to an actuation.

  • Patent number: 8770674
    Abstract: A modulator for a vehicle brake system connected to a central module via a data bus, includes at least one input for capturing measured values and at least one output for controlling at least one electromagnetic valve. A control circuit for actuating the valve is connected by the bus such that the measured values are transmitted to the central module. Control commands for actuating the valve are calculated from the measured values in the central module, and are transmitted via the data bus to the modulator so that the it selects the valve as a function of the commands. A vehicle system has at least two modulators and a central module integrated in a modulator. The modulator can be used as a pressure modulator in an air suspension system or in an electronic braking system or in a conventional braking system with an anti-lock braking system or an electronic stability program.

  • Patent number: 8708430
    Abstract: A pneumatic vehicle brake system includes first and second groups of wheel brakes belonging, respectively, to first and second brake circuits having first and second compressed air storage tanks for providing first and second stored pressures. At least one first circuit brake cylinder is a combined spring-store/diaphragm cylinder with a spring store part for providing a parking brake and a diaphragm part for providing a service brake. If the first circuit fails, the spring store part is deaerated to engage the parking brake. A pressure sensor for measuring the first stored pressure is connected to a control unit that controls a modulator for aerating and deaerating the spring store part. The control unit generates a signal for an electrically actuatable modulator solenoid valve if the value measured by the sensor falls below a minimum value, such that the spring store part can be aerated and deaerated via the valve.

  • Patent number: 8702179
    Abstract: A brake system for a vehicle includes brake cylinders operated by pressurized fluid for actuation of brakes by means of pressurized fluid on at least one first axle of the vehicle. The brakes on at least one other, second, axle can be actuated exclusively electromechanically in response to an electrical braking request signal. The pressure of the pressurized fluid can be modulated indirectly or directly and the electrical braking request signal can be generated indirectly or directly in response to actuation of a brake pedal of a brake pedal device. A service brake function is provided by means of hybrid use of the brakes on the first axle(s) together with the brakes on the second axle(s). The brake cylinders operated by pressurized fluid are pneumatically operated brake cylinders. The pressure modulated by the brake pedal device is a pneumatic pressure, and the pressurized fluid is compressed air.

  • Patent number: 8651588
    Abstract: An electro-pneumatic brake control device is provided for controlling the parking brake of a vehicle having compressed-air-actuated brake cylinders, at least one of which is a spring brake cylinder with a spring store part. Valve devices place the brake control device into various operating states. In a first operating state, the valve devices are at least partially supplied with current and switched such that a compressed air line to the spring store part of the spring brake cylinder is aerated. In a second state, the valve devices are at least partially supplied with current and switched such that the compressed air line is deaerated. In a third state, which can be activated in the event of failure of the electrical energy supply of the brake control device, the valve devices are switched to a currentless state such that the compressed air line is automatically deaerated in throttled manner.
