摘要： The present invention relates to a linear unit for applying an axial force, made of a rotation-translation gearbox (2) comprising a threaded spindle (18) and a threaded nut (19) disposed in a gearbox housing (22), and of an electric motor (1) having a rotor (12) and a stator (12) disposed in an electric motor housing (10). In order to simplify the construction of the linear unit while simultaneously reducing the required installation space, the threaded spindle (18) is axially fixedly and rotatably mounted in the interior of the gearbox housing (22), and is connected to the rotor (12) outside of the gearbox housing (22).

摘要： The invention relates to a method for operating a brake system for motor vehicles, which can be actuated in a "Brake-by-Wire" operating mode both by the vehicle driver and also independent of the vehicle driver, preferably operated in the "Brake-by-Wire" operating mode, and which can be operated in at least one fall-back operating mode, in which only operation by the vehicle driver is possible. The brake system has,
inter alia , an electrohydraulic pressure and volume setting device (5), which electronically emits a brake system pressure under control, and a pressure modulation unit having, for each wheel brake (8, 9, 10, 11), an inlet valve (6a-6d) and an outlet valve (7a-7d) for setting wheel-specific brake pressures. For setting wheel-specific brake pressures, the inlet and outlet valves (6a-6d; 7a-7d) are actuated analogously by being energised by different electrical currents, in order to assign a pressurising agent volume flow already provided by the pressure and volume setting device (5) to the wheel brakes (8-11) that have a pressure change requirement. The invention further relates to a brake system.-

摘要： The invention relates to a method for operating a brake system for motor vehicles, comprising a master brake cylinder (12) that can be acuated by means of a brake pedal (1) and is separably (14a, 14b) connected to at least one hydraulically acutuatable wheel brake (6) by means of at least one brake circuit (I, II), a hydraulically operable pedal travel simulator (19) that is or can be connected to the master brake cylinder (12), an electrically controllable pressure provision apparatus (4) that is separably (27a, 27b) connected to the brake circuit (I, II), and an electronic open-loop and closed-loop control unit (7), wherein when the brake pedal (1) is actuated, a pressure (P
target ) of the pressure provision apparatus (4) is applied to the brake circuit (I, II) in a first operating mode (Z
A ) and the pressure (P
THZ ) of the master brake cylinder (12) is applied to the brake circuit (I, II) in a second operating mode (Z
P ), and wherein in the event of a transition from the second operating mode (Z
P ) to the first operating mode (Z
A ) while the brake pedal (1) is actuated, the actuation travel (S
Pedal ) of the brake pedal (1) is adjusted by means of electronic open-loop or closed-loop control. The invention further relates to a brake system.-

摘要： The invention relates to a method for monitoring a brake system for motor vehicles, which can be actuated both by a vehicle driver and independently of the vehicle driver in what is known as a "brake-by-wire" mode, comprising a hydraulic actuation device (2) which can be actuated by means of a brake pedal (34) and has a main brake cylinder, to which wheel brakes (6) are connected, in particular in at least two brake circuits (12, 13), a simulation device (40), which comprises at least one elastic element (30) and gives the vehicle driver a comfortable pedal feeling, an electrically controllable pressure-providing device (3), which is formed by a cylinder/piston assembly, the piston (46) of which can be actuated by an electromagnetic actuator (47), wherein a first measurement variable (P
DBE ) characterising the pressure of the pressure-providing device (3) is detected, and an electronic control unit (5), wherein a second measurement variable (S
DBE ) characterising a position of the piston (46) is detected, and wherein the detected measurement values of the first and second measurement variables (S
DBE , P
DBE ) are compared (30) to a predetermined characteristic map (31) of the first and second measurement variables in order to monitor a functional status of the brake system. The invention further relates to a brake system.-

摘要： The invention relates to a brake system for motor vehicles that can be actuated in a "brake-by-wire" operating mode both by the vehicle driver and independently of the vehicle driver, and that is operated preferably in the "brake-by-wire" operating mode, and that can be operated in at least one fallback operating mode wherein only operation by the vehicle driver is possible. The brake system comprises an electrohydraulic pressure generating device (5) outputting a brake system pressure, and a pressure modulation unit comprising one inlet value (6a - 6d) and one outlet valve (7a - 7d) per wheel brake (8, 9, 10, 11), tapped from the brake system pressure, wherein the inlet and outlet valves (6a - 6d, 7a - 7d) output or pass along the brake system pressure in the non-actuated state. In order to prevent irritations to the driver of the vehicle, particularly if the electrical on-board network of the motor vehicle fails, according to the invention, circular electrically actuated switching valves (37, 47) are connected between the pressure generating device (5) and the pressure modulation unit, said valve producing a hydraulic connection between the pressure generating device (5) and the pressure modulation unit in an actuated state.
