摘要： The invention relates to an electrically controllable pressure provision device (5, 5'), particularly for a hydraulic motor-vehicle brake system, comprising a stepped bore (54), which is arranged in a housing (53, 21), and a piston (51), which can be actuated by an electromechanical actuator (35, 36). The piston (51), together with the housing (53, 21), delimits a pressure chamber (50). The piston (51) is constructed as a stepped piston, the smaller-diameter piston step (51') of which enters the smaller-diameter step (54') of the stepped bore after a specified actuation of the stepped piston, such that the pressure chamber (50) is subdivided into a first pressure chamber (55) and a second pressure chamber (56). The invention further relates to a brake system for motor vehicles having such a pressure provision device.

摘要： The invention relates to a "brake-by-wire" type braking system for a motor vehicle, comprising a brake pressure transducer which can be actuated by means of a brake pedal of a pedal unit and can be connected to wheel brakes of the vehicle outside of the "brake-by-wire" operating mode, comprising a pressure source which can be controlled by means of an electronic control unit and can be connected to the wheel brakes of the vehicle in the "brake-by-wire" operating mode, comprising means for detecting a deceleration request of a driver, and further comprising a pedal travel simulator which interacts with the brake pedal and is formed by at least one simulator element and by means of which a restoring force acting on the brake pedal in the "brake-by-wire" operating mode can be simulated independently of the control of the pressure source. In order to provide a simpler and more cost-effective "brake-by-wire" type braking system, according to the invention a force-distance characteristic of the pedal travel simulator 2 is controllable.

摘要： The invention relates to a master cylinder (1), especially for a regulated brake system. Said master cylinder comprises at least one piston (3,4;53,54) that can be displaced in a housing (2) and is sealed, by means of a sealing element (5,6) arranged in an annular groove (23,24) of the housing (2), from a pressurised region (7,8) that can be connected to a pressureless wake region (11,12) by means of transversal boreholes (9,10;50,51) in the piston (3,4;53,54). The invention is based on the fact that the inner side (13,14;59,60) of the piston (3,4; 53,54) is provided with recesses (15,16,17) in which the transversal boreholes (9,10;50,51) end.

摘要： The invention relates to an electrohydraulic brake system for motor vehicles that can be controlled in a brake-by-wire mode both from the driver as well as independently of the driver. The brake system is preferably operated in the brake-by-wire mode and can also be operated in a fallback mode in which it can only be operated by the driver. The aim of the invention is to increase the operating reliability of the brake system and/or to provide a brake system which is capable of supplying sufficient hydraulic volume in all driving situations. To this end, the system has means (5,16,16',17,17',40;5,30,29,33,34;47;52,53,54,55,110) for providing a hydraulic volume flow that ensures in the fallback mode at least the hydraulic volume required for the respective delay.
