摘要： An actuator unit for an electro-hydraulic brake system of the ‘brake-by-wire’ type, the first and second pistons thereof being preloaded by a resetting spring each in opposition to the actuating direction. The first pressure chamber of the tandem master cylinder is connected to a hydraulic chamber limited by a simulator element. On the other hand, the simulator element defines a simulator chamber that accommodates a simulator spring and is connected to a pressure fluid reservoir. A valve device is provided to open or close the hydraulic connection between simulator chamber and pressure fluid reservoir. To increase the reliability in operation of a hydraulic fallback mode, at least one channel portion through the pressure chamber, closed at the edge at least in areas, is provided for the purposeful removal of pressure fluid contaminants by means of a compulsory pressure fluid scavenging operation.

摘要： The present invention relates to an operating unit for an electrohydraulic braking system of the ‘brake-by-wire’ type, which is designed as a tandem master cylinder having a first and a second piston biased by each one resetting spring in opposition to the actuating direction. The first pressure chamber of the tandem master cylinder is connected to a hydraulic chamber defined by a simulator element. The simulator element also defines a simulator chamber accommodating a simulator spring and connected to a pressure fluid supply reservoir. A valve device is provided which closes or opens the hydraulic connection between the simulator chamber and the pressure fluid supply reservoir. To disclose an operating unit that permits being manufactured at low costs and allows easy bleeding, according to the present invention, the simulator element is formed of a hydraulic simulator piston and the valve device is provided by a seal arranged at the second piston and by the mouth area of a channel designed in the range of movement of the seal, the said channel forming the hydraulic connection.

摘要： The present invention relates to an actuation device for an electrohydraulic brake system of the ‘brake-by-wire’ type which is configured as a tandem master cylinder with a first and a second piston that are respectively biased by a resetting spring in opposition to the actuating direction. The resetting spring associated with the first piston is additionally used as a travel simulator spring which determines the pedal characteristics, and a valve device is provided which closes or opens a hydraulic connection between a pressure chamber accommodating the travel simulator spring and a pressure fluid supply reservoir. To ensure that only a small lost travel must be covered in the event of failure of the independent brake force, the present invention discloses that the valve device is adapted to be closed by the movement of the second piston in relation to the housing of the tandem master cylinder, and is formed by a sealing sleeve arranged at the second piston and a channel that is designed in the area of movement of the sealing sleeve and connected to the pressure fluid supply reservoir.

摘要： The present invention relates to a vehicle brake system with a pneumatic brake booster which includes an input member being actuated by a vehicle operator and an output member as well as a control housing that carries a movable wall and accommodates a reaction plate at least in part, wherein there is further provision of means for detecting the point of maximum boosting of the pneumatic brake booster that can be used for the actuation of another brake force boosting device. The core of the present invention lies in that a switching or sensor means is provided with senses the maximum boosting force on the basis of a maximum deformation of a reaction element that is indirectly arranged between an output element and a movable wall in that the maximum approach between the output member representative of the output force and the movable wall representative of the booster force is sensed. Further, appropriate means sense the hold time during which the mentioned signal is applied. Only when the signal is applied during the total hold time, a signal reporting the point of maximum boosting is output.
