摘要:
A compressed-air system for supplying a compress-air injection module of a turbocharged internal combustion engine and the pneumatic systems of the vehicle comprises a compressor is provided. The compressor is connected via a line to a pressure accumulator for the supply of a compressed-air injection module and to a device for compressed-air preparation having an air dryer and a pressure regulator for supplying pressure circuits for compressed-air-actuated consumers. The line for supplying the compressed-air injection module branches off upstream of the device for compressed-air preparation.

A method is provided for controlling an output torque of an automated transmission coupled to an internal combustion engine and having a transmission controller. The internal combustion engine includes an exhaust gas turbocharger and an injection air device for injecting air into an intake line. The method receives a torque requirement by the transmission controller, generates an injection air signal by the transmission controller based on the torque requirement and current operating parameters of the internal combustion engine and the automated transmission, and controls the output torque by activating the injection air device based on the injection air signal for injecting air into the intake line of the internal combustion engine for a duration to be determined. A corresponding device is provided for carrying out the method.

A parking brake for a commercial vehicle equipped with an air-operated service brake is configured in such a way that the actuating energy for the brake is reduced in comparison to a configuration with a spring brake cylinder, while the installation space in the wheel area is minimized. Primary functional parts of the parking brake include an inner race and an outer race, which delimit an annular gap. Displaceable tapered-roller bearings are located in the annular gap. To adopt a release position in opposition to the action of a compression spring, the tapered roller bearings are disengaged from the conical surfaces of the inner race and the outer race.

A clamp device inserted between two parts can prevent a relative movement between a brake disc and a brake caliper of a vehicle brake. The device includes two plates, with adjustable separation by way of at least two rollers running against each other and rolling on roller surfaces on facing inner sides of the plates. When the rollers are located in the region of a first section of the roller surfaces, the separation of the plates for bringing about clamping in an extended state is greater than the separation adopted by the plates to generate clamping in a withdrawn state when the rollers are located in the region of a second section of the roller surfaces. The position of the rollers relative to the roller surfaces may be altered by an actuator.

A method and system for automatic braking is described. A service brake which can be operated electrically with a compressed air pressure and a parking brake which can be operated electrically are provided. When the vehicle stops due to the service brake being applied, the service brake is released and the parking brake is applied as a function of a release criterion. The release criterion includes the parking brake not being applicable manually because of a defect, and the operation of a control element for application of the parking brake.

A method is provided for brake pressure distribution between the axles of a vehicle with a pressure medium brake, which vehicle includes rotational speed sensors, which rotational speed sensors are assigned to wheels which can be braked and which rotational speed sensors serve as actual value sensors. The brake pressure distribution between axles is regulated as a function of a difference in wheel rotational speeds between axles or wheel slip values between axles at the axles, and the exceedance of a predefined limit value by the difference in the wheel rotational speed between axles or the wheel slip values between axles during a braking process serves for the regulation of the brake pressure distribution (differential slip regulation). On the basis of the dependency between at least the brake pressure (p) at the rear axle (HA) and the deceleration (z) of the vehicle after at least two preceding service braking operations, a critical deceleration value (Zabheb) is determined by interpolation or extrapolation, in which at least the brake pressure at the rear axle (HA) is less than a predefined brake pressure limit value.

A utility vehicle having several electric devices is described. The vehicle includes an electric steering device and/or an electric braking device, which are controlled by at least one electronic control device, in addition to a pedal unit having pedals, such as a gas pedal, a brake pedal and/or a clutch pedal, which are mounted on a pedal support. The at least one control device and the pedal unit may be incorporated in order to form an integrated component or module.
