The invention relates to a braking system (16) for a vehicle (10), particularly a commercial vehicle, having an operating brake device for providing an operating brake function for braking the vehicle, and a parking brake device (92) for providing a parking brake function independently of the operating brake system. In order to improve the functionality of the braking system in case of a fault, the vehicle can be braked automatically by means of the other braking device if one of the two braking devices partially or completely fails. The invention further relates to a brake pedal device for such a braking system.

Brake equipment for holding and braking an elevator car in an elevator installation, which is arranged to be movable along a brake track in two directions of travel, includes a mount with a brake lining which automatically adjusts under friction couple with the brake track on movement of the elevator car relative to the rail and in that case tightens a first tightening means, which can be released by an actuator. The first tightening means tightens the mount together with the brake lining against the brake track by a biasing force. The brake equipment produces, with unmoved brake equipment and an unreleased state of the actuator, a holding force acting in both directions of travel. The holding force is determined substantially by the biasing force acting on the mount.

The invention relates to a braking system comprising: a master cylinder (1) and a master cylinder housing (20), to which wheel-brake cylinders can be connected; a first piston (2), which is coupled to a brake pedal (3) via a pressure rod (34) that transmits actuating forces; a second piston (4), which is used to actuate the master cylinder (1); a third piston (5), which can be hydraulically actuated by the first piston (2); at least one elastic element (6, 7), which forms a pedal travel simulator and which during the brake-by-wire mode gives the vehicle driver a comforting pedal sensitivity; elements for coupling the displacement of the first (2) and the third piston (5); an intermediate chamber (11) that can be subjected to a hydraulic pressure, the influence of the latter causing a hydraulic force to act on the second (4) and third piston (5); and an electrically controlled pressure-provision module (9), which permits the intermediate chamber (11) to be filled with hydraulic fluid and to be evacuated. The aim of the invention is to assist the actuating force even when the electronic controller or the electric energy supply fails. To achieve this, the system is equipped with a fourth piston (8), which can be subjected to two opposing forces by means of the elastic element (6, 7) on the input side and the hydraulic pressure in the intermediate chamber (11) on the output side, and elements (14,19,15) that allow the pressure-provision module (9), in addition to being electrically controlled, to be controlled in accordance with the position of the fourth piston (8), obtained by the aforementioned exertion of forces.

The present invention provides a method and a system for controlling a braking equipment of a motor vehicle in order to activate the braking equipment at a standstill of the motor vehicle such that braking forces are built up which are necessary to keep the motor vehicle in a state of standstill. To this end it is established on the basis of vehicle movements whether the vehicle is at a standstill. If vehicle movements are detected that cannot occur during driving modes of the motor vehicle, the motor vehicle is in a state of standstill. Subsequently, the braking equipment, and in particular a holding brake mechanism included in the braking equipment, are activated. In order to provide braking forces keeping the motor vehicle at a standstill also when it is on a slope, the braking equipment, and in particular the holding brake mechanism, are controlled in response of the vehicle inclination present in the state of standstill.

The present invention relates to a method and a device for controlling braking equipment of a motor vehicle. Here, an operating state of a motor vehicle is determined, in which the motor vehicle is to be brought from a state, in which its speed is not zero, into a state, in which the vehicle no longer moves. If such a transition from a traveling state into a state of standstill is determined, braking equipment of the motor vehicle is controlled such that braking forces are produced, which are capable of bringing the motor vehicle into the state of standstill and / or assisting a vehicle driver in doing this. It is also possible to produce braking forces in the state of standstill, which are capable of holding the motor vehicle in the state of standstill. The present invention additionally enables to assist a vehicle driver when starting a motor vehicle. In this case, an operating state of the motor vehicle is detected in which the motor vehicle is to be brought from a state of standstill into a traveling state. If such an operating state is present, the braking equipment of the motor vehicle is controlled such that the braking forces produced by the braking equipment in the state of standstill are reduced in such a way as to allow a transition into the traveling state and / or to assist the vehicle driver in this respect.

The invention relates to a system (1) having at least one valve device (4, 4', 4'', 4''') for a pneumatically operated brake system (90, 90') of a vehicle, wherein the brake system (90, 90') has the valve device (4, 4', 4'', 4''') and at least one brake (92, 94, 98, 100). By means of the valve device (4, 4', 4'', 4''') a pneumatic brake pressure which can be fed to the brake is adjusted in a controlled manner. According to the invention, the system has at least two variants (12, 14) of the valve device (4, 4', 4'', 4''') which can be used alternatively in the brake system (90, 90'). Here, a first variant (12) is configured as a modulator for use in an electronically regulated embodiment of the brake system (90), and a second variant (14) is configured for use in a pneumatically controlled embodiment of the brake system (90'). However, both variants (12, 14) of the valve device (4, 4', 4'', 4''') have pneumatic interfaces (24, 26, 28, 30) and mechanical fastening points (16, 18, 20, 22) which are configured identically with respect to one another. Furthermore, the invention relates to the valve device (4, 4', 4'', 4''') for the system (1), and a brake actuation device (6, 6', 6'''), a trailer control valve device (8, 8') and a device for controlling (10, 10') in each case for this system (1). Moreover, the invention relates to a brake system (90, 90') for a vehicle with at least one replacement component (2) of the system (1), to the vehicle, the use of a component of a brake system as component (2) of the system (1), and a method for retrofitting a brake system, in which method a component of the brake system is replaced by a component (2) of the system (1) according to the invention.

This invention relates to a double-sided equipment for a braking system, comprising a first braking pad, a second braking pad, a braking component, a fixing spring component, a compression spring, and an electromagnet, wherein the braking component located between the first braking pad and the second braking pad is movable along the axle of the door operator but is unrotatable with respect to the door operator axle. As a result of the compression spring, the first braking pad and the braking component will be pushed together towards the second braking pad, thereby the braking component is clamped from its two sides by the two braking pads. When the first braking pad is retracted by the electromagnet, the fixing spring enables the braking component to separate from the second braking pad, causing the braking component to be fully separated from the first and second braking pads.
