    摘要: A method and device are disclosed for determining and checking a state or condition of a hydraulic fluid contained in a brake system, including a state of hydration and/or age such that the fluid boiling point is reduced. The boiling point or a characteristic value of the fluid which depends on the boiling point, on the one hand, and the instantaneous temperature value of the fluid, on the other hand, are measured by means of sensor elements. These two values represent a range of permissible comparative temperature values, including a thermal reserve which is within that same range and is determined for further permissible heating of the fluid. A warning signal is released when a predetermined minimum value of the thermal reserve is reached. The sensor elements have hollow spaces with open walls permitting fluid flow-through and have such a design as to ensure that, after heating-up, there comes about a stable cellular convection in a temperature range lying below the boiling temperature. The cellular convection is used as an indication of the condition or the state of the fluid.

    摘要: A brake unit for automotive vehicles with electric drive is configured in the shape of a multiple-circuit compound system consisting of hydraulic friction brakes of brake circuits (I, I', I", III, III', III") and of an electroregenerative brake system (circuit II, II', II"). In a vehicle with a driven and a non-driven axle, three brake circuits exist, one brake circuit of which (I, I', I") is comprised of a pedal-actuated hydraulic brake pressure master unit (2) and of friction brakes (3, 4) acting upon the non-driven wheels. The second brake circuit (II, II', II") which represents an electroregenerative brake system is directly or indirectly coupled to the brake pedal and acts upon the driven wheels. The third brake circuit (III, III', III") which is comprised of friction brakes (10, 11) also acts upon the driven wheels. The actuation of the wheel brakes (10, 11) is connected to the second and third brake circuits. The distribution of the brake power to the front axle (VA) and to the rear axle (HA) is controlled with the aid of an electronic controller (7, 7',7").

The sensor element is in the form of a linear conductor (13', 20, 21) clamped on either end. The sensor element also may comprise a plurality of linear conductors (13', 20, 21) of this type connected in parallel or in series.

    摘要: A brake system for automotive vehicles is equipped with devices for the electric control of the brake force distribution and/or for the control of slip. The front wheels are connected to a pedal-actuated braking-pressure generator (1). In contrast thereto, the rear wheels (HR, HL) are acted upon with braking pressure by virtue of a braking pressure generator unit (5) which is composed of a vacuum servo unit (6) and a master cylinder (7) and which is actuated by a multidirectional control valve (4), such as a three-way/three-position rotary spool valve. The switch position of the valve (4) is responsive to the electric output signals of an electronic combining circuit (17, 17') which is, by way of wheel sensors, furnished with information about the rotational behavior of the wheels and the output of which circuit is electrically connected to the drive (19) of the three-way/three-position rotary spool valve (4). The brake energy for the rear-wheel brakes and the auxiliary energy for boosting the brake pedal force are taken from a vacuum source (Vac).

    摘要: A brake pressure modulator for a brake skid-controlled brake system for automotive vehicles is disclosed including a volume take-up device including a plunger disposed in a cylindrical chamber and preloaded by a spring into the cylindrical chamber. The plunger is closely guided out of the cylindrical chamber to the outside and is connected to a driving mechanism which upon occurrence of a brake skid signal at least in part pulls the plunger out of the cylindrical chamber to expand the volume thereof and to thereby decrease the brake pressure. Provided between the driving mechanism and the plunger is a gear of a transmission ratio variable depending on the plunger position.

    摘要: In a piston-cylinder assembly for hydraulic brake systems of automotive vehicles, the piston is at least partially composed of ceramics. A hydraulic seal is interposed between the piston and the cylinder. To simplify the assembly while allowing comparatively great tolerances, the seal is fitted at the end of the piston that is adapted to be mounted close to a pressure chamber within the system. The seal is provided with radially-extending projections which cause the piston to spring back by a roll-back effect.

    摘要: This brake system contains a braking pressure generator aggregate which influences the rear axle braking pressure so as to control the braking force distribution between front and rear axles in dependence on the static and dynamic axle load distribution and on other parameters resulting from the braking behavior. The braking pressure generator aggregate is connected to a tandem master brake cylinder and pressurized by an operating pressure, the braking pressure generator aggregate reduces in a ratio corresponding to a basic rating of the braking force distribution and makes available for basic rear axle braking pressure. The tandem master brake cylinder thus performs the major part of the braking operation at the rear axle. A vacuum servo drive is a part of the braking pressure generator aggregate and is activated in order to raise or lower the braking pressure at the rear axle above or below the basic braking pressure. In doing so, the vacuum servo drive performs but a small part of the braking operation at the rear axle.
